Brief Summary:
Thirty-six completely edentulous healthy patients received four mandibular implants and were randomly divided into the following groups: (A) The implants were installed by fully guided stereolithographic stent (n = 18), and (B) The implants were installed by semi-guided stereolithographic stent. (n = 18). The accuracy analysis was performed by one experienced process engineer (DB). Cone beam computed tomography was performed before and after the surgical procedure to plan the virtual implant position and fabricate the surgical guide, as well as to determine implant position deviations. Both CBCT scans were superimposed, and the software compared preoperative linear and angular virtual measurements of planned implants with real measurements of the placed implants.
Detailed Description:
Objectives: Current study aimed to assess the accuracy of fully- guided implant placement in completely lower edentulous patients compared to the semi-guided protocol.
Materials and Methods: Thirty-six completely edentulous healthy patients received four mandibular implants and were randomly divided into the following groups: (A) The implants were installed by fully guided stereolithographic stent (n = 18), and (B) The implants were installed by semi-guided stereolithographic stent. (n = 18). The accuracy analysis was performed by one experienced process engineer (DB). Cone beam computed tomography was performed before and after the surgical procedure to plan the virtual implant position and fabricate the surgical guide, as well as to determine implant position deviations. Both CBCT scans were superimposed, and the software compared preoperative linear and angular virtual measurements of planned implants with real measurements of the placed implants. Measurements and analysis of results were performed by means of a software tool used during virtual planning (P3Dental; Protótipos).
