The aim of this study was to evaluate the 1-year success rate and marginal bone loss for dental implants placed simultaneously with bone grafts.
The study sample comprised 37 patients treated with dental implants placed simultaneous with intraoral block bone grafts. The block grafts were harvested from the chin, retromolar area, or maxillary tuberosity. Complications with the bone grafts were categorized as minor or major and, for the graft success rate, the Barone and Covani criteria were used. The definition of implant success was based on the clinical and radiographic criteria of Albrektsson et al. Peri-implant bone loss was measured after 1 year of prosthetic loading.
The study involved 39 bone grafts (17 maxillary and 22 mandibular) and 129 implants (73 implants in grafted areas) in 37 patients. No complications were observed at the donor sites. A part of the onlay bone graft was exposed in eight sites; six sites showed spontaneous reepithelialization following chlorhexidine application, but two grafts became infected and had to be removed. Three implants were lost in the grafted areas; the success rate for implants with simultaneous bone grafting was therefore 95.9%. No complications were found at 12 months after prosthesis placement. The mean overall bone loss after 1 year of loading was 0.64 mm.
In patients meeting the inclusion criteria, simultaneous placement of bone grafts and implants shortens treatment time without increasing complications or reducing the success rate.
本研究旨在评估同期骨移植与种植体的 1 年成功率和边缘骨丧失。
研究样本包括 37 例同期接受口腔内块状骨移植与种植体治疗的患者。块状移植物取自颏部、磨牙后区或上颌结节。将骨移植并发症分为轻度和重度，并用 Barone 和 Covani 标准评估移植体的成功率。根据 Albrektsson 等人的临床和影像学标准，将种植体成功定义为基于临床和影像学标准。在修复体负重 1 年后测量种植体周围骨丧失。
本研究涉及 37 例患者的 39 个骨移植（17 个上颌骨和 22 个下颌骨）和 129 个种植体（73 个种植于移植区）。供区无并发症。8 个部位的覆盖式骨移植部分暴露；6 个部位在应用洗必泰后自发上皮化，但 2 个移植物感染，必须取出。在移植区有 3 个种植体丢失；因此，同期骨移植种植体的成功率为 95.9%。在修复体放置 12 个月后未发现并发症。负荷 1 年后总骨丢失的平均值为 0.64mm。
在符合纳入标准的患者中，同期放置骨移植和种植体可缩短治疗时间，而不会增加并发症或降低成功率。
