Adhesive residue on the CAD-CAM surgical guide sleeve: A technical report

A Novel Method for Precise Guided Hole Fabrication of Dental Implant Surgical Guide Fabricated with 3D Printing Technology

“…The spread of dental 3D printers is increasing, and the use of guides during implant surgery is being made and applied at the dental chairside environment [1][2][3][4][5][6][7][8][9]. The method presented in this technique is proposed to fabricate a surgical guide with minimum tolerance without the use of a metal drill key or a separate metal sleeve with the equipment (implant planning software and 3D printer) and printing materials readily available to clinicians.…”

“…Numerous studies have evaluated the accuracy of the surgical guides [2][3][4][5][6]. Previous studies reported that the inaccuracies in the guided hole of the surgical guide can affect the accuracy of implant positioning [3,7,8]. Previously, a metal drill key was placed on the guided hole of the surgical guide to prevent inaccuracies [7].…”

“…Previously, a metal drill key was placed on the guided hole of the surgical guide to prevent inaccuracies [7]. Alternatively, the inaccuracy of the guided hole was resolved by fastening a separate metal sleeve to the prepared surgical guide using an adhesive [8]. However, these methods can lead to another inaccuracy [3,8].…”

“…An important factor for accurate implant positioning is the tolerance of the guide holes in the surgical guide [3][4][5][6][7][8][9]. Although it would be ideal for the drill and guide hole of the surgical guide to be precisely matched, it is impossible to insert the drill into the guide hole without tolerance.…”
