Study Details

Study Description

Brief Summary

The main objective of this prospective, controlled, and randomized clinical study is to evaluate the peri-implant bone loss of immediately loaded versus conventionally loaded implants with a single prosthesis. A split-mouth experimental design will be used, and the success rate of the installed implants will be determined. Twelve selected patients (corresponding to a minimum of 24 surgical implant sites) will receive endosseous Ti dental implants. The protocol for preparing the surgical sites will be based on the manufacturer's recommendations and bone density. Patients with an initial torque less than 30 N·cm and an implant stability quotient (ISQ) less than 60 will be excluded from the research. Envelopes, indicating which site is the test site, will be opened after the implants are installed. Transfer impressions of the implants receiving immediate loading will be produced so that temporary crowns can be made. Temporary crowns will be installed a maximum of 24 hours after the surgery, by using the torque recommended by the manufacturer. Appropriate occlusal adjustment will be made to ensure minimal contact at maximum intercuspation and absence of contacts during protrusive and lateral excursive movements of the jaw. At baseline (time of implant installation) and 3, 6, 9, and 12 months after implant installation, the following aspects will be evaluated: the initial torque at the moment of implant insertion, Osstell ISQ, pain in the implant when subjected to vertical and horizontal forces, clinical mobility of the implant, crestal bone loss around the implant (as determined by x-ray evaluation), probing depth around the implant, and periodontal pain.

  • Outcome Measures

    Primary Outcome Measures

    1. Bone Loss of Immediate Versus Conventional Implants as determined by x-ray evaluation [12 months]
