Abstract
Statement of Problem
Conventional freehand implant placement protocols relied on the pre-operative radiographs for planning of implant placement. The need for a more predictable and planned approach led to the advent of computer-assisted implant placement protocols.
Purpose
A prosthetically driven implant placed according to the planned implant position helps the surgeon avoid complications like inadvertent damage to surrounding vital structures, undesired implant angulation, bone loss or inadvertent perforation. Surgical guides serve as a template to transfer the planned implant position to the actual anatomic site with improved predictability and accuracy.
Materials and Methods
Six electronic databases were thoroughly searched with specific MeSH terms for randomized control trials, non-randomized control trials, prospective studies and in vitro studies in last ten years till 2023 for the evaluation of accuracy between freehand and fully guided implant placement protocols following the PRISMA 2020 guidelines for this systematic review and meta-analysis.
Results
The initial search revealed 2202 articles from which 10 articles were selected. A fully guided technique uses surgical guide for placement of both the drills and the implant, whereas the conventional freehand approach relies only upon the pre-operative radiographs and the surgeon’s expertise for implant placement. Angular deviation and apical deviation are the most vulnerable parameters susceptible to error without the use of a surgical guide.
Conclusion
Accuracy of fully guided implant surgery is better than freehand implant surgery in all the parameters mentioned above. Significant improvement was noticed for angular deviation, apical deviation, 3D deviation (base) and 3D deviation (apex). This is the first systematic review to include the comparison of linear and 3D spatial deviation and compare the six deviation parameters together.
