Guided vs free-hand surgery

Complications from guided and freehand surgery

A recent study from Barcelona has compared the prosthetic and biological complications of freehand and guided full-arch restorations.

The authors stated that guided surgery with a CAD/CAM template should be more precise than the freehand method, and should therefore result in fewer complications. To test this, they conducted a cross-sectional review of clinical files from Clinica Universitaria de Odontologia. Complications which were recorded as part of the study included tooth detachment, ceramic chipping and implant removal (among others).

From the files, 99 patients were selected. Eleven patients had undergone guided surgery and the remaining 88 surgeries were performed freehand. For the guided surgery group 50% of the prostheses experienced complications, the most prevalent of which was ceramic chipping. Almost two thirds of prostheses from the non-guided surgery group experienced complications. Tooth replacement accounted for over half of these complications. The authors note the small sample size of the guided surgery group means that further study is required to obtain more clinically relevant results.

This study was presented as an e-poster at the 2018 EAO Congress.

Great! Thanks for sharing this study! If I can recommend, the study I presented at the 2018 EAO also addressed guided virtual surgery.
