前牙缺失窄间隙的种植技巧

The implant skill on the narrow clearance of up-front teeth

目的探索利用种植技术修复上前牙窄间隙缺失的方法。方法选取21例上前牙窄间隙缺失的病例，利用正畸的方法尽可能的开大间隙，必要时进行邻牙片切。将测量的数据还原，进行实际操作，术后各项数据和Anthoyr系统金标准对比。结果种植体近中骨量与金标准相比，P=0．3826，P〉0．05种植体远中骨量与金标准相比，P=0．5465，P〉0．05。种植体实际植入位置与理想位置无明显差异。结论利用平分间隙的方法可以较精确的确定种植体的种植位置。可以避免牙槽间隙的吸收和龈乳头的退缩。从而使窄间隙上前牙缺失的种植修复趋于完美。

Objective To explore the method of rehabilitating the narrow clearance of up-front teeth by implant. Methods 21 cases like that were treated by opening clearance with diorthosis. Some teeth were cut. For an example of Anthoyr to ensure the implant place by the angle deuce line between two tangents of the fang. To ensure the implant is deuce the bone in clearance. This is Golden standard. Reverting the data to operate, contrasting the data after operating with Golden standard, the results were found. Results This method can ensure the bone measures beside the implant are up of 1.5 mm. There is no evidence difference between both. Conclusion It can ensure the implant place exactly using the method of clearance deuce. It can avoid absorb of tooth bone and cower of mammilla of gum. So the implant restoration for the narrow clearance of up-front teeth goes to perfection.
