Guided implant surgery in the edentulous maxilla: A systematic review

Abstract

© 2016 by Quintessence Publishing Co Inc.Purpose: This systematic review verified the usefulness/limitations of static surgical guides during implant surgery in the edentulous maxilla. The PICO question was: "Does the use of digitally generated surgical guides vs conventional techniques affect the following outcomes: surgical complications, implant complications, prosthesis complications, implant survival, prosthesis survival, economics, patient satisfaction, and maintenance intervention?" Materials and Methods: The electronic searches retrieved 2,588 unique articles from which eventually 36 full-text articles were read for eligibility. Because no randomized controlled clinical trials could be found, the PICO question had to be reformulated, now only looking to the outcome of digitally generated surgical guides without comparison with conventional techniques. Results: Although long-term data are lacking, the outcome of implants placed with a static guide and of the prosthetic reconstruction seems similar to that expected from conventional techniques. The number of surgical complications with guided surgery is negligible. Guided flapless implant surgery offers slightly more comfort for the patient; however, the economic benefits are unclear. Conclusion: Implant therapy via static surgical guides in the maxilla is predictable, with slightly more comfort for the patient but with only minor economic advantages.
