A case report of occlusal reconstruction for a generalized severe chronic periodontal disease with recovery anterior guidance by strategic anterior teeth extractions and implant prosthetics

Abstract

In occlusal reconstruction, it is often the case that horizontal overlap of the anterior teeth is excessive in Angle II and insufficient in Angle III, which makes it difficult to obtain anterior guidance. Considering the occlusal function, it is important whether the anterior guidance mechanism works properly and allows disocclusion to the molars during lateral movement. Inadequate anterior guidance is likely to cause tooth wear and excessive load on the TMJ, and long-term stability of the dentition would be a bleak picture1) . In this study, we report a case of a Class II skeletal patient with generalized severe chronic periodontitis, in which strategic tooth extraction and prosthodontic treatment were combined to achieve sound anterior guidance.
