Research significance of removable partial denture

1. When the patient refuses bone augmentation surgery due to insufficient bone in the alveolar bone, is in poor economic condition, or suffers from systemic diseases that cannot withstand a wide range of surgeries, the addition of implant support to the traditional removable partial denture with clasps is a better method; compared with fixed implant restorations, it reduces the number of implants, which alleviates the patient's surgical pain and economic burden; and it is accessible for cleaning at night to avoid extra load on natural teeth and implants, while allowing the alveolar ridge to rest. nighttime to avoid additional loading of the natural teeth and implants, while allowing the alveolar ridge to rest.

2. Ohkubo et al. compared the occlusion of an implant-supported RPD and a conventional retainer-type RPD in patients with Ken's class I. The results showed that the implant-supported removable partial denture showed greater occlusal force and occlusal contact area, and that implant placement improved denture stability and masticatory function.

3. The implant-supported removable partial denture provided a more stable occlusion with reduced stress on the articular area compared to the clasped removable partial denture, and this restoration may prevent undesirable bone remodeling of the temporomandibular joint.
