Accuracy Of Surgical Guides For Dental Implants In Half Guided Surgery- A Metaanalysis
Keywords:

Purpose-The aim of this meta-analysis was to compare the accuracy of surgical templates in half guided approach in terms of trueness and evaluate their impact on clinical procedures, providing valuable insights for clinicians.
Materials and Methods: A systematic review was conducted following PRISMA and Cochrane Collaboration guidelines to assess the accuracy of surgical guides in half-guided dental implant procedures. A comprehensive literature search was performed using databases like PubMed, CENTRAL, and Embase, applying the PICO approach. Inclusion criteria focused on peer-reviewed studies reporting coronal and apical deviation data. Risk of bias was evaluated using the Newcastle–Ottawa Scale to ensure study reliability.
Results: The review included 11 studies assessing the accuracy of surgical guides in half-guided implant surgery. Coronal deviation ranged from 0.22 to 1.987 mm, while apical deviation varied from 0.19 to 2.24 mm. Meta-analysis showed no significant difference between anterior and posterior sites, with overall deviation being low. Statistical analysis confirmed high accuracy (p<0.00001) despite study heterogeneity.
Conclusion: This meta-analysis confirms that half-guided implant surgery using digital surgical guides yields high accuracy in both anterior and posterior sites, with no significant site-specific differences in coronal or apical deviation. These findings support the clinical versatility of half-guided protocols in implant dentistry.
