Incorporating Irrigation Channels in Sleeved Surgical Guides.

A critical stage in dental implant procedures involves preparing the implant site via surgical drilling. Adequate irrigation during this process is crucial to prevent thermal damage to the surrounding bone tissue. While surgical guides significantly improve the accuracy of implant site preparation by directing drill movement, they can also obscure the operative field and impede effective coolant delivery. This report presents design modifications to surgical guides compatible with the Straumann® system (Institut Straumann AG, Switzerland) to enhance coolant access and optimize temperature control during drilling. Three types of surgical guides were developed using specialized computer-aided design software. The first design is a conventional guide without irrigation channels. The second incorporates a single irrigation channel, while the third-an innovative prototype-features a dual-channel irrigation system. In both modified designs, the irrigation outlets are strategically positioned below the lower edge of the guiding sleeve to improve coolant delivery to the drilling site. The results confirm the feasibility of producing this new dual-channel surgical guide. Implantology professionals can replicate and evaluate this design by following the outlined modifications, thereby enhancing both safety and efficacy in guided implant surgery.
