Abstract
Bilateral distal implants to support a class I removable partial denture demonstrates the conversion of the removable partial denture from tooth-tissue supported to tooth-implant supported. Aim of the work: This study was carried out to answer the question if the endosseous implant design philosophy can be used to eliminate the deleterious effect of the intracoronal attachment removable partial denture on the abutment teeth and ridge for distal extension case, regards alveolar bone height change? Materials and methods: Eight patients of maxillary completely edentulous arches against mandibular bilateral distal extension ridges were divided into 2 equal groups. One group received mandibular intracoronal attachment removable partial overdenture which is supported by bilateral distal single implant, while the other group received conventional mandibular intracoronal attachment removable partial denture. Comparison was done between the 2 groups after 6 and 12 months regarding bone height changes of abutment teeth using periapical radiographs, and bone height changes of mandibular distal extension ridges, and the marginal bone loss related to the distal implant abutment using panoramic radiographs. Results: Along the interval period of study, significant alveolar ridge resorption was observed for both groups, abutment teeth alveolar bone resorption was significantly less in the group received bilateral distal implant. However, significant crestal implant bone loss was observed along the follow-up period. Conclusion: Single distal implant abutment may be the school of thought when mandibular distal extension intracoronal attachment removable partial denture is the treatment of choice regards preservation of natural abutment alveolar bone from loss.
