The aim of this study was to evaluate the split-crest technique with ultrasonic bone surgery for implant placement in patients with narrow ridges, focusing on the status of soft and hard tissues and on implant success rate, at least 6 months after implant loading.
During September 2007 and November 2008, 15 patients received 37 implants (BTI implants) with split-crest surgical procedure using ultrasonic bone surgery. Plasma rich in growth factors (PRGF®) was applied during split crest procedure to promote tissue regeneration. Implant surfaces were humidified with PRGF to accelerate osseointegration. Patients were recalled for a final clinical evaluation at least 6 months after implant loading. Clinical assessment included the status of soft and hard tissues around implants, and implants' success rate.
Thirty-seven implants in 15 patients were evaluated between July 2009 and January 2010. The status of soft tissues was very good, showing adequate plaque index, bleeding index, and probing depth values. Success rate of implants at the end of follow-up (between 11 and 28 months after insertion) was 100%. Bone ridge was measured and compared at final examination showing a mean ridge expansion of 3.35 mm (SD: 0.34).
Split-crest with ultrasonic bone surgery can be considered an effective and safe procedure for narrow ridge expansion.
本研究旨在评估超声骨手术在牙槽嵴狭窄患者中进行种植体植入的分瓣技术，重点关注软硬组织状况和种植体成功率，至少在种植体负荷后 6 个月。
2007 年 9 月至 2008 年 11 月，15 名患者接受了 37 枚 BTI 种植体（使用超声骨手术进行分瓣手术）。在分瓣过程中应用富含生长因子的血浆（PRGF®）以促进组织再生。将 PRGF 湿润种植体表面以加速骨整合。在种植体负荷后至少 6 个月，患者进行最终临床评估。临床评估包括种植体周围软硬组织的状况和种植体的成功率。
2009 年 7 月至 2010 年 1 月对 15 名患者的 37 枚种植体进行了评估。软组织状况非常好，显示出适当的菌斑指数、出血指数和探诊深度值。在随访结束时（插入后 11 至 28 个月），种植体的成功率为 100%。最终检查中测量并比较了牙槽嵴，显示平均牙槽嵴扩张 3.35 毫米（标准差：0.34）。
超声骨手术的分瓣技术可被视为一种用于牙槽嵴扩展的有效且安全的方法。
