Accuracy of Fully Guided Versus Half Guided Implant

October University for Modern Sciences and Arts16 enrolled

Overview

six implants will be placed in edentulous maxilla to rehabilitate patients with implant prosthesis.The primary outcome measure will be the accuracy of implant placement, which will be evaluated using cone-beam computed tomography (CBCT) scans

Study Design: This will be a Split mouth randomized controlled trial (RCT) study. 16 patients missing teeth in the maxillary (upper) jaw and eligible for dental implant treatment will be recruited. Interventions will be randomly assigned to the right or the left side of the arch : Group 1 will undergo fully guided dental implant surgery. Group 2 will undergo partially guided dental implant surgery. Study Duration: The total duration of the study is estimated to be 5 months. Recruitment and enrollment of patients: 1 months Dental implant surgery : 3 months Data analysis and manuscript preparation: 1 months The key steps are: Recruit 16 eligible patients missing teeth in the maxillary jaw. Randomly assign right or left side of the maxillary arch of patients to either the fully guided or partially guided implant surgery group. Perform CBCT (cone-beam computed tomography) scans before and after the implant surgery for both groups. Assess the accuracy of implant placement in both groups using the CBCT data. Conduct statistical analysis to determine if there are any statistically significant differences in implant placement accuracy between the two groups. Interpret the results and develop recommendations on the optimal guided surgery technique for rehabilitating the edentulous maxilla using dental implants. The study aims to provide scientific evidence to guide clinicians in selecting the most appropriate guided surgery approach for maxillary implant rehabilitation

The key difference is that in Group 1, the guide is only used for the drilling sequence, while in Group 2 the guide is used for both the drilling and the actual implant placement.

Outcomes

Primary Outcomes

Rate of Angle Deviation in Implant Placement: Fully Guided vs. Half-Guided Approaches

Post-surgery, 16 patients will be scanned using the same CBCT machine and exposure settings. Preoperative and postoperative CBCT scans will be imported into the In2Guide™ software, where an overlay of the preoperative plane onto the postoperative scan allowed for precise evaluation of implant positioning. Implant deviations will be measured in three directions: angular deviation, deviation at the coronal platform (entry deviation), and deviation at the apical portion (Figure 2). The software generated coordinates for the necessary calculations, with coronal and apical deviations reported in millimeters and angular deviation in degrees.
