Combination Using of Minimally Invasive Bone Splitting, Bone Condensing, Guided Bone Regenerationin Vertical Ridge Augmentation and Simultaneous Installation of Narrow-diameter Implants
摘要
Abstract
Objective: To report a clinical application of combination using of minimally invasive bone splitting, bone condensing, guided bone regeneration (GBR) and immediate planting. Methods: A 58-year-old male with an unmarkable medical history requested replacement of missing lower teeth with an implant-supported restoration. Clinical examination revealed the patient's mandibular teeth were all missing except 42,43 retained in loose condition. There were vertical and horizontal defects of the residual alveolar ridge of the mandible. Imagiology examination showed in 33 rd and 34 th tooth site area, available bone width was 4 mm, available bone height was 13-15 mm; in 43 rd and 44 th tooth sites, the width/height of alveolar were, 5 mm/12-16 mm; in 36 th and 34 th tooth site area, 8 mm/12 mm respectively. Bone density of the mandible appeared normal. Various augmentation techniques were discussed in detail with the patient and eventually the patient decided to undergo ridge augmentation with the combination using of minimally invasive bone splitting, bone con-densing, and guided bone regeneration. The procedure was carried out under local anesthesia. Then minimally invasive bone splitting and bone condensing were performed in proposed implant area of left lower mandible with simultaneous placement of titanium-zirconium narrow diameter implants. The remaining implants were placed routinely in other sites, GBR was performed around the buccal exposed implants. Results: 4 months later, multi-base abutments were used to make resin fused to titanium crown prosthesis. Finally, 12 units of permanent prosthesis supported by 6 implants were re-stored. Conclusion: Combination using of minimally invasive bone splitting, bore condeusing, and GBR, is successful in this case, bnt lorg time observation is stll necessary.关键词
