The flat and step (F and S) pontics. Novel pontic designs for periodontally reconstructed sites

OBJECTIVE: Fixed dental prostheses are a predictable treatment option to replace missing teeth. A periodontal-prosthodontic approach to rehabilitating those areas ensures a predictable way to achieve the desired esthetic and functional results. This is especially important in cases with high esthetic demand. An ideal esthetic result can be achieved by soft tissue overcorrection through periodontal procedures, which reduce the number of conditioning appointments of the pontic sites. Many pontic designs have been described to enhance the appearance of the restored sites. The flat (F) and step (S) pontic designs are a modification of classic pontic approaches. These designs contact the mucosa in a wide area of a previously reconstructed ridge without exerting excessive pressure, reducing the possibility of inflammation, ulceration, and facilitating cleaning. This periodontal-prosthodontic procedure aims to achieve functional and esthetic prosthodontic results in a predictable manner. CLINICAL CONSIDERATIONS: Understanding which pontic design is recommended in different clinical situations is key for a successful outcome. The F and S pontic designs are recommended to be used in a ridge with optimal soft tissue volume after periodontal reconstruction. The suggested designs provide the clinician with a solution to different clinical scenarios after the periodontal augmentation of the pontic site has been done. CONCLUSIONS: The presented pontic designs are indicated in ridges where a previous soft tissue preservation or reconstruction procedure has been done to achieve an optimal soft tissue volume. Modifications to the designs can be done in the interim stage which is later replicated into the final restoration. CLINICAL SIGNIFICANCE: The combination of periodontal and prosthodontic techniques help to predictably achieve a natural looking pontic emergence profile.
