摘要：

目的　探讨利用数控机床（computer numerical control, CNC）制造个性化下颌无牙颌金属种植导板的新方法。方法　8具下颌无牙颌标本随机分为两组，分别运用CNC技术加工出金属导板、运用快速成型（rapid prototyping, RP）技术加工出树脂导板并测量其在体外实验中辅助置钉的精确性。结果　CNC与RP导板在下颌骨中部水平面上的绝对偏差分别为(0.23±0.14) mm、(1.01±0.27) mm，差异有统计学意义（P=0.000）；在矢状面上分别为(0.30±0.24) mm、(0.95±0.24) mm，差异有统计学意义（P=0.000）。结论　在体外实验中，CNC金属下颌无牙颌种植导板辅助种植精确性高于RP树脂导板。

Abstract:

Objective　To explore a new method for manufacturing customized edentulous mandible metal implant surgical guides using computernumerical control (CNC) machines.　Methods　Eight corpse edentulous mandibles were randomly divided into two groups, CNC metal guides and rapid prototyping (RP) resin guides were manufactured respectively. All guides were used to assist edentulous mandible implantations to analyze the accuracy in vitro.　Results　The absolute deviation on horizontal plane was (0.23±0.14) mm in the CNC group and (1.01±0.27) mm in the RP group, respectively, between which the difference was significant (P=0.000). The absolute deviation on sagittal plane was (0.30±0.24) mm in the CNC group and (0.95±0.24) mm in the RP group, respectively, between which the difference was significant (P=0.000).　Conclusions　In vitro implantations, CNC surgical guides assisted implantations have higher accuracy than RP guides.
