目的:评价前牙区行微创骨劈开术并同期植入种植体的临床疗效。方法:前牙缺失患者15名,植入种植体21颗。缺牙区牙槽嵴呈薄刃状,宽度约2～4mm,平均为3.3mm。局部浸润麻醉下行嵴顶小切口,微翻瓣,仅暴露嵴顶部分,先锋钻定位,刃状骨凿将颊舌侧骨板分开并将颊侧骨板向外移位,基底部仍与基底骨相连,形成青枝骨折,相应扩孔钻行种植窝的精确预备并收集自体骨屑,同期植入种植体,两侧的骨沟隙内填入自体骨屑或自体骨与人工骨混合物,严密缝合创口,术后6个月行二期手术。结果:术后CBCT影像未见唇侧骨板折断、游离,患者术后疼痛、肿胀等不良反应轻微,二期手术时可见种植体周围骨成形理想,修复完成后种植体行使功能良好。讨论:微创骨劈开术可以减小创伤,保留骨组织并提高种植体周围骨密度,同期植入种植体缩短了患者就诊疗程,保存牙槽嵴劈开后的骨宽度,该技术应用于前牙区能取得良好的临床效果。结论:微创骨劈开术是解决前牙区水平骨量不足的一种可预测的有效的骨增量方法。
Objective: To evaluate the clinical effect of minimally invasive bone dissection in the anterior region and simultaneous implantation of implants. Methods: There were 15 patients with anterior teeth missing and 21 implants. Edentulous alveolar ridge was thin blade, the width of about 2 ~ 4mm, an average of 3.3mm. Local infiltration of anesthesia down the crest of a small incision, flap slightly, only the crest exposed part of the vanguard drilling positioning, osteotomy osteotomy buccal and lateral separation of the buccal plate, the basal part is still with the base Bone formation, the formation of green branch fractures, the corresponding reaming drilling row planting nest accurate preparation and collection of autologous bone chips, implantation of implants at the same time, both sides of the bone gap filled with autologous bone chips or autologous bone and artificial bone mixture, Suture the wound tight, six months after surgery line two. Results: There was no fracture of the labial plate in CBCT images after operation, and the pain, swelling and other adverse reactions were slight after operation. The second stage of operation showed that the peri-implant bone was ideal, and the implants had good function after repair. Discussion: Minimally invasive osteotomy can reduce the trauma, retain the bone tissue and improve the bone density around the implant, the same period implant implants shorten the patient treatment, preservation of the alveolar ridge cleft bone width, the technology used in Anterior teeth area can achieve good clinical results. Conclusions: Minimally invasive osteotomy is a predictable and effective method of bone augmentation to solve the problem of insufficient bone mass in the anterior tooth area.
