Implant Retained Dentures
-
Bridging is type of fixed dental restoration which is done to replace the missing teeth by joining an artificial tooth definitely with neighboring teeth or dental implants.
-
Westcoast dental clinic in Surat specializes in all types of bridging.
Conventional bridge
- Conventional bridging is built using high translucent zirconium with VM9 vita porcelain and stained with luster paste. Here the upper first premolar is considered the pontic and the teeth prepared are abutments.
- Full coverage crowns, three-quarter crowns, post-retained crowns, onlays and inlays on the abutment teeth support the conventional bridges.
- For supporting the prosthesis, the abutment teeth require preparation and reduction.
- Conventional bridges are named depending on the way the pontic (false teeth) is attached to the retainer.
-
Fixed-fixed bridges
- It refers to the false tooth which is attached to a retainer at both the sides of the space with only one path of insertion. Here the design has a connector at both the ends which is fixed and which connects the abutment to the false tooth (pontic).
- Because the abutments are connected together tightly it is crucial that during preparation of the tooth the nearest surfaces of the abutment teeth must be prepared such that they stand parallel to each other.
-
Cantilever
- In a cantilever bridge, a pontic is attached to a retainer at only one side. The abutment tooth may be mesial or distal to the pontic.
- A cantilever is a bridge where a pontic is attached to a retainer only at one side. The abutment tooth may be nearer or farther to the pontic.
-
Spring cantilever
- The Spring Cantilevel bridge has the pontic and retainer remote from each other connected through a metal bar. Usually, a posterior tooth supports and replaces a missing anterior tooth. This bridge’s design supersedes the other.
-
Fixed-movable
- In fixed movable bridge, the pontic is firmly attached to a retainer at one end of the major retainer and attached to a movable joint at the other end of minor retainer.
- A major advantage of this bridge is that the movable joint can accommodate the angulation differences in the abutment teeth in long axis, which enables the path of insertion to be irrespective of the alignment of the abutment tooth. This enables a more conservative method as the abutments do not need to be prepared so that they are parallel to one and other. Ideally the fixed connector should attach the pontic to the farther abutment. The movable connector attaches the pontic to the near abutment, enabling this abutment tooth to make limited movement in vertical direction.
