Background Implant‐simulation software can now be used to improve treatment planning, guide surgery, and ensure more accurate implant placement. Purpose The aim of this study was to evaluate the outcome of a guided surgery protocol versus a conventional protocol. Materials and Methods Twenty‐six patients were randomly assigned to Guided Surgery or Conventional Surgery. In test group implants were placed in the maxilla using a tooth supported model‐based surgical guide with a minimally invasive flap and immediately loaded. In control group implants were inserted with an open flap surgery following a prosthetic stent and immediately loaded. Results A total of 70 implants were placed (36 test and 34 control). Statistically significant differences were found between the test group and the control group for patient opinion about self‐confidence, assumption of analgesic tablets and perceived pain. The test group registered a statistically significant reduction ( p < .05) as regards time of surgery and time of provisional insertion with respect to the control group. Conclusions Implants can successfully integrate in the posterior maxilla using a guided surgery approach with immediate loading. The use of guided surgery helped to reduce the surgery duration, pain intensity, related analgesic consumption, and a more predictable provisional installation.
