Abstract

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.
