Fixed Dental Bridge
A fixed
dental bridge is a restorative dental procedure used to replace one or more
missing teeth. It is "fixed" because it is permanently anchored to
natural teeth or implants and cannot be removed by the patient. Below is a
detailed overview of the procedure:
1. Purpose of a Fixed Bridge
- Replace Missing Teeth: Restore function (chewing,
     speaking) and aesthetics.
- Prevent Shifting: Avoid neighbouring teeth
     from drifting into the gap, which can cause misalignment.
- Support Facial Structure: Maintain the shape of the
     face and prevent sagging.
- Improve Oral Health: Ensure even bite pressure
     and prevent undue stress on remaining teeth.
2. Types of Fixed Bridges
- Traditional Bridge:
- Most common type.
- Consists of one or more
      false teeth (pontics) held in place by dental crowns on adjacent natural
      teeth.
- Cantilever Bridge:
- Used when there’s only one
      adjacent supporting tooth.
- Not ideal for areas with
      significant bite pressure.
- Maryland Bonded Bridge:
- Uses a framework of metal
      or porcelain bonded to the back of adjacent teeth.
- Less invasive, as it
      doesn’t require crowns.
- Implant-Supported Bridge:
- Anchored to dental implants
      instead of natural teeth.
- Ideal for multiple missing
      teeth and offers superior stability.
3. Fixed Bridge Procedure Steps
Step 1: Consultation and Diagnosis
- Examination: Dentist evaluates oral
     health, checks for gum disease, and assesses adjacent teeth.
- Imaging: X-rays or 3D scans to
     analyze bone structure and identify underlying issues.
- Treatment Plan: Dentist determines the
     appropriate type of bridge based on the patient’s needs.
Step 2: Tooth Preparation
- For Traditional and
     Cantilever Bridges:
- The abutment teeth (teeth
      adjacent to the gap) are reshaped to accommodate dental crowns.
- The dentist removes a
      portion of enamel and dentin for the crown to fit properly.
- For Implant-Supported
     Bridges:
- Dental implants are
      surgically placed into the jawbone to serve as artificial tooth roots.
- Healing time (3-6 months)
      may be needed for osseointegration (fusion of implants with bone).
Step 3: Impressions
- The dentist takes
     impressions or digital scans of the prepared area.
- These are sent to a dental
     lab to fabricate a custom bridge.
- Temporary Bridge: A temporary bridge may be
     placed to protect the prepared teeth and maintain functionality.
Step 4: Fabrication
- The dental lab creates the
     bridge using materials like porcelain, zirconia, or metal-fused porcelain.
- The final bridge is
     customized for fit, bite alignment, and color matching.
Step 5: Fitting the Bridge
- The dentist removes the
     temporary bridge and tests the fit and bite of the permanent bridge.
- Adjustments are made to
     ensure proper alignment and comfort.
Step 6: Cementation
- The permanent bridge is
     cemented onto the abutment teeth or attached to implants.
- Excess cement is cleaned
     off, and the bite is rechecked.
