Clinical Trial Summary

The objective of this randomized and longitudinal clinical study is to compare the installation of immediate implants in the esthetic zone through computer-guided-surgery and conventional surgery. To this end, 22 patients who need implant-supported replacement on the anterior region of the maxilla will be selected and after extraction will receive: Guided surgery (GS): installation of dental implant with the aid of the virtually planned guide by means of specific software; Conventional surgery (CS): installation of dental implant performed freehand using a conventional surgical guide made by study models.


Clinical Trial Description

The objective of this randomized and longitudinal clinical study is to compare the installation of immediate implants in the esthetic zone through computer-guided-surgery and conventional surgery. To this end, 22 patients who need implant-supported replacement on the anterior region of the maxilla will be selected and after extraction will receive: Guided surgery (GS): installation of dental implant with the aid of the virtually planned guide by means of specific software; Conventional surgery (CS): installation of dental implant performed freehand using a conventional surgical guide made by study models. Tomographies will be performed 10 days after the surgery for the measurement of both linear and angular shifts between the installed implants and the virtual planning. All the clinical and radiographic assessments (Plaque and Bleeding Index, Drilling Depth, Relative Clinical Insertion Level and the Margin Position of Peri-Implant Mucosa) will be carried out after the surgery and within 6 and 12 months of post-operative. Assesments of the esthetic success (pink/white score) and survival and success of the implant will also be carried out. In the prosthetic part, it will be assessed the abutment mobility; corrective measures for the prothesis; repair on prothesis or abutment. The success and survival assessments of crowns will be done through structure fracture, occlusal roughness, marginal integrity and contour of the restoration. It will also be assessed the procedural impact in quality of life by applying a 36-closed-question-survey focused on appearence, pain, oral comfort, general performance, feeding and chewing. Subsequently, the data will be tabulated, and according to their distribution, the appropriate statistical tests will be applied, considering a 5% index of significance to all the analyses. ;
