Abstract
Because of minimal trauma and shorter treatment durations, immediate implant has becoming prevalent. Immediately placed implant after teeth extraction is an efficient technique for preserving bone while, also restoring function and aesthetics. To provide enough proper implant-bone contact and stability of the immediate implant, the inter-radicular bone must be preserved during extraction. This will prevent the implants from sliding into the empty sockets. Our study’s goal was to assess the accuracy of root-guided and computer-guided techniques.
Objectives: Investigation of accuracy and stability of immediately placed implant utilizing two techniques (Root-Guided versus Computer-Guided Techniques).
Materials and Methods: this study was a randomized control clinical trial (RCT). Twenty-four patients were randomly allocated into two groups: group I twelve immediate implants were placed by (Root-Guided Technique) and group II twelve immediate implants were placed by (Computer-Guided Technique). Osstell was used to determine the primary stability intra-operative. After 3 months the secondary stability was assessed again by Osstell. Post-operative Cone Beam Computer Tomography was done immediately after surgery for both groups evaluating the implant accuracy.
Results: Throughout the study, 24 implants were effectively operating, in both groups. The accuracy of implants was significantly higher in (group II) in comparison with (group I). Three months postoperative ISQ values for all implants increased with (group II) having significantly higher increase.
Conclusion: The computer-guided technique showed more accuracy and stability when compared with root-guided technique.
Keywords: Immediate implant placement, Root-guided technique, Computer-guided technique.
