Denture: Overdenture and Bar Connectors
Overdentures have significant advantages compared with complete dentures. Some of these are:
1. Greater functional stability due to preservation of residual ridge contours
2. Better retention
3. Chewing efficiency
4. Less pressure on the mucosa
5. Reduced extension of denture base in the maxilla
Overdentures are complete dentures that are partially supported by natural teeth or implants. Overdentures are superior to conventional complete dentures in biting force, chewing efficiency and force discrimination.
Classification of Overdenturess based on how long the denture is expected to be worn.
- Immediate Overdenture
- Transiotional Overdenture
- Definitive Overdenture
Overdenture Abutments Connected by a Bar
Bar connectors have the following indications
- Periodontally weakened abutment teeth where direct splinting by a bar is needed
- Roots that will accommodate only short dowels
- Bar connector offers grater mechanical stability
