Comparison of precision of implant placement between two different guided systems for static computer-assisted implant surgery: A simulation-based experimental study

Abstract

Background/purpose: Many designs of static computer-assisted implant surgery (sCAIS) are available for clinician to achieve proper implant position. However, there were not any studies that approached the design alone to evaluate whether sleeve-in-sleeve or sleeve-on-drill design provided most accuracy implant position. The purpose of this study was to investigate the precision of implant placement with sleeve-in-sleeve and sleeve-on-drill static computer assisted implant surgery (sCAIS) designs. Materials and methods: Thirty-two models were fabricated simulating a patient with bilateral missing first premolar. Eight models (sixteen implants) were assigned in each group: Group A, B and C represented sleeve-in-sleeve design with 2, 4 and 6 mm sleeve height respectively. Group D represented integrated sleeve-on-drill design with 4 mm sleeve height. 3D deviation at implant platform, apex and angular deviation were measured. Data were analyzed using one way ANOVA (P 0.05). Conclusion: Sleeve-in-sleeve sCAIS demonstrated higher precision than sleeve-on-drill sCAIS.
