Accuracy of chairside-milled CAD/CAM drill guides for dental implants.

Purpose: To describe a chairside method for producing implant guides based solely on digital data and present a first assessment of in vitro accuracy on plaster models.

Material And Methods: Twenty-four implants were planned and pilot drillings were performed according to a new protocol, which is based on the registration of CBCT and CAD/CAM data. Chairside-milled one-piece drill guides were used to transfer the virtual plan into reality.
