The purpose of this study was to evaluate the stability of tapered resorbable blasting media surface implants in the posterior maxilla.
From September 2008 through January 2010, 20 patients (9 men, 11 women) who were treated with tapered GS III implants at Seoul National University Bundang Hospital were identified. Thirty-eight implants (14 premolar and 24 mol/L) were placed in maxillary posterior areas.
The patients' mean age was 52.1 years, and the mean follow-up period was 12.6 months after final prosthesis delivery. The implant length was 11.8 ± 1.4 mm with a diameter of 4.6 ± 0.5 mm. The 1-year survival rate was 97.4%, and the success rate was 94.7%. The implant stability quotient value at implant placement was 63.6 and 74.4 at the second surgery, which indicated a significant difference. There was no significant difference in crestal bone loss according to implant diameter or length or sinus bone graft.
This study showed the favorable clinical outcome of tapered implants that were placed in the maxillary posterior area.
本研究旨在评估锥形可吸收爆破介质表面种植体在上颌后区的稳定性。
从 2008 年 9 月至 2010 年 1 月，在首尔国立大学盆唐医院，我们确定了 20 名（9 名男性，11 名女性）接受锥形 GS III 种植体治疗的患者。在上颌后区共植入 38 枚种植体（14 颗前磨牙和 24 颗磨牙）。
患者的平均年龄为 52.1 岁，最终修复体交付后平均随访 12.6 个月。种植体长度为 11.8±1.4mm，直径为 4.6±0.5mm。1 年的存活率为 97.4%，成功率为 94.7%。种植体植入时的种植体稳定性系数值为 63.6，第二次手术时为 74.4，差异有统计学意义。种植体直径或长度或窦骨移植与颊侧骨吸收无显著差异。
本研究表明，在上颌后区植入锥形种植体具有良好的临床效果。
