Accuracy of Fully Guided Versus Half Guided Implant

NCT06542562 | Completed DMC

• 1 other identifier: UMSA
• Study Type: interventional
• Target: 16
• Locations: 1 country
• Sites: 1

Brief Summary

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

Conditions

Complete Edentulism

Keywords

implants

Outcome Measures

Primary Outcomes (1)

• 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.

Study Arms (2)

Group 1 will undergo fully guided dental implant surgery

EXPERIMENTAL

Group 1 will undergo fully guided dental implant surgery

Procedure: guided implant placement

Group 2 will undergo half guided dental implant surgery

EXPERIMENTAL

Group 2 will undergo half guided dental implant surgery. Where the implant will be placed after removal of the guide

Procedure: guided implant placement

Interventions

guided implant placement PROCEDURE

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.

Group 1 will undergo fully guided dental implant surgery; Group 2 will undergo half guided dental implant surgery
