Autogenous grafting of gingival or bone tissue is often indicated to obtain optimal esthetics and function in periodontal and implant therapy. In the present study, 32 maxillary teeth were extracted, and the postextraction defects were treated with 32 autogenous cylindric free gingival-bone grafts retrieved with trephine burs from intraoral donor sites. Free gingival-bone grafts were also used to obtain root coverage and papilla reconstruction in three patients who required esthetic enhancement. Twelve to 16 weeks after the graft procedure, biopsies were retrieved and processed for histologic evaluation to verify integration of the grafts. The implants placed in the treated sites healed without complications and were functionally loaded after healing. The clinical and histologic results of this study suggest that the free gingival-bone graft technique may favor hard and soft tissue reconstruction of the sites treated, with esthetic and functional advantages.
在牙周治疗和种植治疗中,为获得最佳的美学效果和功能,常采用自体牙龈或骨组织移植。在本研究中,拔除了32颗上颌牙,拔牙后的缺损用32块从口腔供区用环钻获取的自体圆柱形游离牙龈-骨移植物进行治疗。游离牙龈-骨移植物还用于3例需要美学改善的患者的牙根覆盖和乳头重建。移植手术后12至16周,取出活检组织进行组织学评估,以验证移植物的整合情况。植入治疗部位的种植体愈合良好,无并发症,愈合后进行功能加载。本研究的临床和组织学结果表明,游离牙龈-骨移植技术可能有利于治疗部位的软硬组织重建,具有美学和功能优势。
