Ridge Expansion and Immediate Placement With Piezosurgery and Screw Expanders in Atrophic Maxillary Sites: Two Case Reports

摘要: Endosseous dental implants may require bone augmentation before implant placement. Herein is described an approach to edentulous ridge expansion with the use of piezosurgery and immediate placement implants. This allow for a shortened treatment time elimination donor-site morbidity. Two cases are reported. technique uses piezoelectric device cut crestal proximal facial cortices. Space then created motorized osteotomes widen split ridge. allows narrow, anatomically limiting, atrophic ridges, creating space The lingual cortices provide support vital osteocytes osteogenesis. 2 patients presented had adequate height but narrow ridges. In patient 1 at site #11, crest was 3.12 mm thick expanded accept 4.3 × 13 implant. resulting width 8.88 mm, which verified using cone beam computerized tom...
