Fixed Dental Prosthesis in Rangsit

Fixed dental prostheses are restorations that are attached to natural teeth or dental implants and are not normally removed by the patient.

They may be used to restore a damaged tooth, protect weakened tooth structure, replace one or more missing teeth, improve chewing function or support a broader dental rehabilitation plan.

Common fixed restorations include dental crowns, bridges, inlays, onlays and implant-supported crowns or bridges.

At SWC Dental in Rangsit, the suitable restoration is selected after examining the remaining tooth structure, gums, bite, supporting bone, neighbouring teeth and existing dental work. Not every damaged or missing tooth requires the same type of fixed prosthesis.

What Is a Fixed Dental Prosthesis?

A fixed dental prosthesis is a dental restoration that is cemented, bonded or screwed into position and cannot normally be removed by the patient.

Depending on the clinical situation, a fixed prosthesis may be supported by:

• A natural tooth
• Several natural teeth
• One or more dental implants
• A combination of suitable supporting structures

Fixed prosthetic treatment may include:

• Dental crowns
• Dental bridges
• Implant-supported crowns
• Implant-supported bridges
• Inlays
• Onlays
• Selected fixed full-arch restorations
• Veneers in appropriate cases

The term describes a group of treatments rather than one standard procedure.

The dentist must determine whether the supporting tooth or implant is healthy enough to carry the proposed restoration and whether the design can be cleaned and maintained appropriately.

What Problems Can Fixed Dental Restorations Address?

Fixed prosthetic treatment may be considered for several dental concerns.

A tooth with extensive structural damage

A tooth affected by a large cavity, fracture, wear or a large existing filling may not have enough structure for a direct filling alone.

Depending on the amount of healthy tooth remaining, the dentist may recommend:

• An inlay
• An onlay
• A partial-coverage restoration
• A dental crown
• Another suitable restorative option

The most extensive restoration is not automatically the best choice. Whenever appropriate, treatment planning should consider preserving healthy tooth structure.

A tooth after root canal treatment

A tooth that has received root canal treatment may require a suitable final restoration.

The need for a crown, onlay or filling depends on:

• Which tooth was treated
• How much natural tooth structure remains
• Existing cracks
• Size of previous restorations
• Biting forces
• Location in the mouth
• The dentist’s assessment of fracture risk

Root canal treatment addresses the tissue inside the tooth but does not replace the missing outer tooth structure.

One or more missing teeth

A fixed dental bridge may replace a missing tooth by using suitable neighbouring teeth or dental implants for support.

A missing tooth may also be replaced with:

• A dental implant and crown
• A tooth-supported bridge
• An implant-supported bridge
• A removable denture
• No immediate replacement in selected situations

The appropriate choice depends on the location of the gap, supporting teeth, available bone, gum health, bite and patient preferences.

Worn or shortened teeth

Teeth may become worn from grinding, clenching, erosion, an unstable bite or a combination of factors.

Selected teeth may be rebuilt with onlays, crowns or other restorations, but the cause of the wear should be assessed before definitive treatment.

Restoring worn teeth without considering the contributing factors may increase the risk of future fracture or restoration failure.

Failing existing restorations

An older crown, bridge, filling or onlay may require assessment if it becomes:

• Loose
• Fractured
• Chipped
• Difficult to clean
• Painful during biting
• Associated with new decay
• Associated with gum inflammation
• Visibly different from neighbouring teeth

A restoration should not automatically be replaced based on age alone. The dentist should examine its fit, function, surrounding tooth structure and current symptoms.

Types of Fixed Dental Prostheses

Dental crowns

A crown is a restoration that covers most or all of the visible part of a prepared tooth.

A dental crown may be considered when a tooth:

• Has lost substantial structure
• Contains a very large filling
• Is cracked or fractured
• Has severe wear
• Requires protection after selected root canal treatment
• Needs alteration of shape or function
• Supports part of a dental bridge

A crown requires preparation of the tooth. The amount of tooth reduction depends on the material, design and clinical condition.

Not every tooth with a filling or root canal treatment requires a full crown.

Dental bridges

A dental bridge replaces one or more missing teeth with an artificial tooth connected to supporting crowns, implants or another suitable fixed design.

A conventional tooth-supported dental bridge typically involves:

• An artificial replacement tooth called a pontic
• One or more supporting teeth called abutments
• Fixed retainers placed on the supporting teeth

The supporting teeth must be carefully assessed because they carry additional load and may need preparation.

Implant-supported crowns

An implant-supported crown replaces a missing tooth without relying on neighbouring natural teeth for direct support.

Treatment normally involves:

1. Assessment of the missing-tooth area
2. Placement of a dental implant when suitable
3. Healing and integration with the surrounding bone
4. Connection of an abutment
5. Placement of the final crown

Implant suitability depends on the available bone, gum health, medical history, oral hygiene and other individual factors.

Implant-supported bridges

An implant-supported bridge may replace several missing teeth using fewer implants than the number of replacement teeth in selected cases.

The design depends on:

• Number and location of missing teeth
• Available bone
• Position of the implants
• Bite forces
• Space for the restoration
• Ability to clean beneath the bridge
• Long-term maintenance requirements

An implant-supported bridge remains fixed for the patient, although a dentist may be able to remove selected screw-retained restorations for maintenance or repair.

Inlays

An inlay is an indirect restoration that fits within the prepared cavity of a tooth without covering the main chewing cusps.

It may be considered when a tooth requires more substantial restoration than a small direct filling but still has sufficient healthy structure.

Onlays

An onlay is an indirect restoration that covers and protects one or more cusps of a tooth.

An onlay may provide cuspal protection while preserving more tooth structure than a full crown in suitable cases.

The choice between a filling, inlay, onlay and crown depends on the extent of damage, remaining tooth structure, tooth position and biting forces.

Veneers

A veneer is a thin restoration bonded to the front surface of a tooth.

Veneers primarily address selected concerns involving colour, shape, proportion or limited surface damage.

They are not intended to replace missing teeth or restore every severely damaged tooth.

Fixed Prosthesis Compared with a Removable Denture

A fixed prosthesis and a removable denture differ in how they are supported and maintained.

Topic	Fixed dental prosthesis	Removable denture
Removal by patient	Normally cannot be removed	Removed by the patient
Support	Teeth, implants or both	Teeth, implants, gums or a combination
Cleaning	Cleaned in the mouth	Removed for cleaning
Tooth preparation	May be required	Depends on the design
Replacement of multiple teeth	Possible in suitable cases	Often suitable for larger spaces
Bone requirements	Important for implant-supported treatment	May be possible without implant placement
Adjustment and repair	May require professional removal or replacement	Can often be adjusted outside the mouth
Suitability	Depends on support and span	Depends on remaining teeth and oral anatomy

A fixed option is not automatically appropriate for every patient. A removable prosthesis may be more suitable when several teeth are missing, support is limited, surgery is not appropriate or the patient prefers a removable solution.

Crown, Bridge or Dental Implant: How Are They Different?

Treatment	Main purpose	Support
Crown	Restore or protect one damaged tooth	Existing natural tooth or implant
Tooth-supported bridge	Replace one or more missing teeth	Neighbouring natural teeth
Implant crown	Replace one missing tooth	Dental implant
Implant-supported bridge	Replace several missing teeth	Multiple dental implants
Removable denture	Replace several or all missing teeth	Teeth, gums, implants or a combination

The choice should consider more than appearance alone. The dentist assesses biological health, remaining structure, maintenance, treatment complexity and long-term risks.

Who May Be Suitable for Fixed Prosthetic Treatment?

A patient may be considered for fixed dental treatment when:

• The supporting tooth can be restored
• The gums are sufficiently healthy
• Tooth decay is controlled
• There is adequate tooth or implant support
• The bite allows a suitable restoration
• The patient can maintain daily oral hygiene
• The treatment area can be kept clean
• The patient understands the limitations and maintenance needs
• The selected treatment aligns with the broader dental plan

Suitability can only be confirmed after examination.

When May Fixed Treatment Need to Be Delayed?

Definitive fixed restorations may need to be delayed when there is:

• Active tooth decay
• Untreated gum disease
• Dental infection
• Inadequate oral hygiene
• An unstable bite
• Insufficient healthy tooth structure
• A tooth with an uncertain prognosis
• Uncontrolled grinding or clenching
• Gum or bone healing after extraction
• Ongoing implant healing
• A need for orthodontic movement
• Medical factors affecting treatment or healing

Temporary restorations may be used while the underlying condition is treated or monitored.

Assessment for a Fixed Dental Prosthesis at SWC Dental

1. Discussion of concerns and goals

The dentist asks about the patient’s main concern, which may include:

• A damaged tooth
• A missing tooth
• Difficulty chewing
• A loose restoration
• Repeated fracture of a filling
• Appearance
• Food trapping
• Sensitivity
• Problems with an existing crown or bridge

2. Examination of the teeth and gums

The clinical examination may assess:

• Tooth decay
• Cracks or fractures
• Existing fillings and crowns
• Gum inflammation
• Gum recession
• Tooth mobility
• Remaining tooth structure
• Supporting teeth
• Available restorative space
• Ability to clean the proposed restoration

3. Dental imaging

Dental X-rays may be recommended to assess:

• Tooth roots
• Bone support
• Decay beneath restorations
• Previous root canal treatment
• Infection near the root
• Supporting teeth
• Implant sites

A CBCT scan may be considered for selected implant or complex cases but is not automatically required for every crown or bridge.

4. Bite assessment

The dentist evaluates how the upper and lower teeth meet.

Excessive or uneven forces may affect restoration design and the risk of chipping, loosening or fracture.

5. Digital scans or impressions

Records of the teeth may be obtained using:

• An intraoral scanner
• Conventional impressions
• Photographs
• Bite records
• Study models

The available workflow depends on the clinical situation and equipment.

6. Treatment options and consent

The dentist explains:

• Restorable and non-restorable teeth
• Fixed and removable options
• Need for root canal or gum treatment
• Proposed materials
• Tooth preparation
• Temporary restorations
• Number of appointments
• Risks and limitations
• Maintenance requirements
• Estimated fees

Fixed Prosthesis Treatment Process

The exact process depends on whether the restoration is a crown, bridge, inlay, onlay or implant-supported prosthesis.

1. Stabilising oral health

Active decay, gum disease or infection should be managed before definitive restorative work.

Treatment may include:

• Professional teeth cleaning
• Gum treatment
• Dental fillings
• Root canal treatment
• Extraction of a non-restorable tooth
• Temporary repair

2. Tooth preparation or implant assessment

For a tooth-supported restoration, the dentist prepares the tooth to create space and a suitable shape for the restoration.

For an implant-supported restoration, the implant position, gum contour and available restorative space are evaluated.

3. Digital scan or impression

A detailed record of the prepared teeth, neighbouring teeth and bite is taken.

This information is used to design and manufacture the restoration.

4. Temporary restoration

A temporary crown or bridge may be placed while the final restoration is being produced.

Temporary restorations help:

• Protect prepared teeth
• Reduce sensitivity
• Maintain tooth position
• Support appearance
• Provide limited chewing function
• Allow evaluation of shape and bite

Temporary restorations are not intended to have the same strength or fit as the definitive restoration.

5. Laboratory or digital fabrication

The restoration may be produced through a dental laboratory, a digital CAD/CAM workflow or a combination of techniques.

The dentist selects the approach according to the material, restoration type, clinical requirements and available system.

6. Trial and evaluation

Before final placement, the dentist may evaluate:

• Fit
• Contact with neighbouring teeth
• Bite
• Shape
• Colour
• Gum relationship
• Ability to clean the restoration

Adjustments may be required before cementation or screw retention.

7. Final placement

The restoration is bonded, cemented or screwed into position according to its design.

The dentist checks the bite and provides cleaning instructions.

8. Review and maintenance

Follow-up may be recommended to evaluate comfort, bite, gum response and cleaning.

What Materials Are Used?

Fixed dental restorations may be made from materials such as:

• Ceramic
• Zirconia
• Porcelain fused to metal
• Metal alloys
• Composite resin
• Hybrid restorative materials

The most suitable material depends on:

• Tooth location
• Biting forces
• Available tooth reduction
• Appearance
• Restoration thickness
• Opposing teeth
• Existing restorations
• Gum position
• Implant design
• Clinical requirements

No single material is universally best for every tooth or patient.

Does Fixed Prosthetic Treatment Hurt?

Local anaesthesia may be used when preparing natural teeth.

Patients may experience temporary:

• Tooth sensitivity
• Gum tenderness
• Jaw fatigue
• Pressure during impressions
• Awareness of a temporary restoration
• Mild discomfort after bite adjustment

Tell the dentist if the restoration feels high, painful, loose or difficult to bite on.

A fixed prosthesis should not be described as completely painless because treatment experience varies.

How Many Appointments Are Required?

The number of visits depends on:

• Type of restoration
• Number of teeth involved
• Need for gum or root canal treatment
• Whether an implant is involved
• Healing requirements
• Material and production method
• Need for temporary restorations
• Complexity of the bite
• Adjustments required

Some indirect restorations may be completed in a limited number of appointments, while complex bridges or implant-supported restorations require a longer treatment sequence.

How Long Does a Crown or Bridge Last?

There is no fixed lifespan that applies to every restoration.

Longevity depends on:

• Condition of the supporting teeth
• Gum and bone health
• Restoration design
• Material
• Fit and bite
• Oral hygiene
• New tooth decay
• Grinding or clenching
• Diet and habits
• Maintenance
• Accidental damage

A crown or bridge may function for many years when appropriately planned and maintained, but no restoration should be presented as permanent for every patient.

Risks and Limitations

Possible risks and limitations may include:

• Temporary or persistent sensitivity
• Need for root canal treatment
• Tooth fracture
• New decay at the restoration margin
• Gum inflammation
• Porcelain chipping
• Restoration fracture
• Loss of cement retention
• Screw loosening in implant restorations
• Food trapping
• Difficulty cleaning
• Changes in the bite
• Damage to a supporting tooth
• Need for repair or replacement
• Implant-related complications
• Aesthetic differences from natural teeth

The dentist should discuss the risks relevant to the proposed restoration.

Caring for Crowns and Bridges

Fixed restorations require daily cleaning.

Recommended care may include:

• Brushing twice daily with fluoride toothpaste
• Cleaning between the teeth
• Using floss threaders beneath bridges
• Using interdental brushes where suitable
• Cleaning around implant crowns
• Attending professional cleaning appointments
• Avoiding chewing ice or very hard objects
• Reporting looseness or fracture
• Managing grinding when indicated
• Following the recommended review schedule

A crowned tooth can still develop decay at the edge of the restoration.

Cleaning Under a Dental Bridge

The artificial tooth in a bridge does not develop decay, but plaque and food can collect beneath it and around the supporting teeth.

Cleaning aids may include:

• Floss threaders
• Super floss
• Interdental brushes
• Water irrigation where appropriate
• Other tools recommended by the dental team

The design of the bridge affects which cleaning method is suitable.

When Should You Contact the Dentist?

Arrange an assessment if you notice:

• A loose crown or bridge
• Pain when biting
• A fractured restoration
• New sensitivity
• Gum swelling or bleeding
• Food trapping that persists
• A bad taste or discharge
• Difficulty cleaning
• Movement around an implant restoration
• A change in the bite
• A temporary crown that has fallen out

Increasing swelling, severe pain, fever or difficulty swallowing requires prompt assessment.

Frequently Asked Questions About Fixed Dental Prostheses

What does fixed prosthesis mean?

It means a dental restoration that is attached to teeth or dental implants and is not normally removed by the patient. Examples include crowns and bridges.

Is a crown a fixed prosthesis?

Yes. A crown is a fixed restoration placed over a prepared natural tooth or connected to a dental implant.

Is a dental bridge removable?

A conventional fixed bridge is not removed by the patient. It is cemented or otherwise attached to its supporting teeth or implants.

Is an implant crown the same as a dental implant?

No. The implant is the component placed in the jawbone. The crown is the visible replacement tooth connected to the implant through an abutment.

What is the difference between an onlay and a crown?

An onlay covers selected damaged areas and one or more cusps, while a crown generally covers most of the visible tooth. The choice depends on the remaining healthy structure and treatment needs.

Does every root canal-treated tooth need a crown?

Not automatically. The appropriate restoration depends on the tooth location, amount of remaining structure, cracks and biting forces.

Can a bridge replace several teeth?

A bridge may replace one or more teeth in suitable cases. The possible span depends on the number and strength of supporting teeth or implants, bite and design.

Can fixed restorations develop cavities?

The restorative material itself does not develop decay, but the natural tooth at the edge of a crown or bridge can still develop a cavity.

Can a fixed bridge be repaired?

Some complications can be adjusted or repaired, while others require removal or replacement of the bridge. The options depend on the material and type of damage.

Which material is best for a dental crown?

No material is best for every case. Selection depends on tooth position, biting forces, available space, appearance and the clinical condition.

What is a crown?

A crown is a cover or “cap” your dentist can put on a tooth. The crown restores the tooth to its normal shape, size and function. The purpose of a crown is to make the tooth stronger or improve the way it looks.

The difference between crown and veneer – Veneer cover only frontal surface of the tooth while crown is placed around tooth.

Benefit of crown

You may need a crown if you:

• have a cavity that is too large for a filling
• have a missing tooth and need a bridge
• need to cover a dental implant
• have a tooth that is cracked, worn down or otherwise weakened
• have had root canal treatment—the crown will protect the restored tooth
• Want to cover a discolored or badly shaped tooth and improve your smile!

 

What is it made from?

Porcelain-fused to metal	Ceramic	Base metal alloys

Crowns are made from several types of materials. Metal alloys, ceramics, porcelain, or combinations of these materials may be used.

• Ceramic — These are used for restoring front teeth, and are popular in this area for their ability to blend with your natural tooth color.
• Porcelain-fused to metal – This crown provides a stronger bond than regular porcelain because it is connected to a metal structure. It’s also extremely durable.
• Base metal alloys – This crown is made up of non-noble metals that are highly resistant to corrosion, and make for a very strong crown. It also requires the least amount of healthy tooth to be removed prior to fitting.

Caring for your teeth

To prevent damage to a crown, there are a few things you can do:

1. Brush twice a day and floss once a day to remove plaque, a sticky film of bacteria.
2. Avoid chewing hard foods, ice or other hard objects, such as pencils. This is especially important for tooth-colored crowns.
3. Be sure to see your dentist every 6 monthsfor regular exams and professional teeth cleanings.

What is a bridge?

A bridge, also known as a fixed removable denture, is made to replace one or more missing teeth. A bridge is made up of two or more crowns for the teeth on either side of the gap — these two or more anchoring teeth are called abutment teeth — and a false tooth/teeth in between.  Bridges can be supported in any of three ways:

• By natural teeth
• By implants
• By a combination of teeth and implants

A traditional bridge is made by creating a crown for the teeth on either side of the space and placing a false tooth or teeth between the crowns. The crowns, sometimes called caps, can be supported by natural teeth or by implants. The false tooth or teeth are attached to the crowns and fill the empty space.

What Are the Benefits of Dental Bridges?

Bridges can:

• Restore your smile
• Restore the ability to properly chew and speak
• Maintain the shape of your face
• Distribute the forces in your bite properly by replacing missing teeth
• Prevent remaining teeth from drifting out of position

Disadvantage

1. There is possibility of caries on dental abutment.
2. The glue or cement used to fix crown might be loose.
3. Regular check-up is needed.
4. Abutment teeth has to be grinded.

How Do I Care for a Bridge?

It is important to keep remaining teeth healthy and strong as the success of the bridge depends on the solid foundation offered by the surrounding teeth. Brushing twice a day and flossing and using an antiseptic mouthwash daily help prevent tooth decay and gum disease that can lead to tooth loss. Keeping a regular cleaning schedule will help diagnose problems at an early stage when treatment has a better prognosis. Selecting a balanced diet for proper nutrition is also important.
