摘　　要：目的:探讨简便可行、微创的下颌磨牙区中重度牙槽骨萎缩牙种植修复的新方法。方法:5例下颌磨牙区牙槽骨中重度萎缩,牙槽骨高度明显不足的病例,种植术前螺旋CT测量下颌神经管的位置,制作种植模板,手术中种植体颊舌向倾斜一定的角度以避开下颌神经,达到种植体的有效种植高度。共种植10mmITI种植体11个,然后择期冠修复。结果:1例因倾斜角度过大而放弃修复,其余10个种植体进行冠修复或桥体修复,其中联冠或单冠修复6个,桥体修复4个。种植修复后观察1-3年,种植体修复均获得成功。结论:下颌磨牙区中重度牙槽骨萎缩牙槽骨高度明显不足的病例,倾斜植入种植体可避免损伤下牙槽神经,达到种植体植入的有效高度,是一种可行、微创、新的种植修复方式。Objection： To report a new simplify implant treatment for severly atrophied posterior mandible. Method： The pilot study included 5 patients,The patients presenting severe atrophy in the posterior mandible （Lekholm 和 Zarb classification VI or V ） were rehabilitated by using implants （10 mm in length; ITI ）. Perioperation the relationship between implant area and mandible nerve was measured with spiral CT. Inclining implant avoided to injure mandible nerve. The criteria used to evaluate implant outcome were： implants function as support for reconstruction; implants stable when individually and manually tested; no signs of infection observed; and good esthetic outcome of the rehabilitation. To evaluate the secondary objective of assessing the stability and health of the soft tissue covering the implants. Result： The cumulative implant survival rate and prosthetic survival rate at 1 year were 100% except a case inclining larger angle was not rehabilitated. Conclusion： The procedure in atrophic posterior mandible, associated with spiral CT measure , may be considered an effective, minimally invasive and well-tolerated procedure for implant prosthetic rehabilitation.
