Accuracy of computer-assisted, template-guided implant placement compared with conventional implant placement by hand—An in vitro study

Abstract

Objectives: To compare free-hand to computer-assisted implant planning and placement (CAIPP) regarding planned to achieved implant position. Material and methods: Forty-eight cast/bone models were mounted in mannequin heads. On each side, a tooth gap of different sizes was created. In the test group (T), study implants were placed using a CAD-CAM guide based on virtual planning. In the control (C), free-hand implant placement was performed. After CBCT scanning, the implant position was compared with the planned position. Descriptive statistics were applied, and ANOVA was used to identify differences between groups and gaps. (p
