Objectives:

The growing interest in minimally invasive surgery, together with the possibility of fitting prostheseswith immediate function, have led to the development of software capable of planning and manufacturing a surgicalguide and prosthesis that can be placed upon conclusion of the implant surgery step.The present study evaluates the surgical and prosthetic complications of implant treatment with the guided surgerytechnique, together with patient comfort during and after treatment.Patients and

methods:

A retrospective observational study was made of 19 patients with partially or totally edentulousupper and/or lower maxillae, involving the placement of a total of 122 implants. All cases were planned andoperated upon with the guided surgery technique.

Results:

A total of 122 implants were placed in 14 males and 5 females. The intraoperative surgical complicationscomprised a lack of primary stability, while the postoperative complications consisted of infections and a lack ofimplant osteointegration. Ten implants failed. The prosthetic complications in turn comprised loosening of theprovisional prosthesis screws, prosthesis tooth fracture, and a lack of passive fit of the immediate prosthesis. Thedegree of patient satisfaction was evaluated using a verbal scale.

Conclusions:

Implant restoration with the guided surgery technique and immediate functional loading is a predictableprocedure, provided patient selection and the surgical technique are adequate, affording lesser postoperativemorbidity and increased patient satisfaction thanks to the immediate restoration of esthetics and function (AU)
