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).
Results:
The overall deviation at platform ranged from 0.40 ± 0.14 mm (group A) to 0.73 ± 1.54 mm (group C), at apex from 0.46 ± 0.16 mm (group A) to 1.07 ± 0.37 mm (group C) and the angular deviation ranged from 0.86 ± 0.89° (group A) to 3.40 ± 1.29° (group C). Group A and B showed significantly less deviation than groups C and D (P < 0.05). There was no statistically significant difference in all parameters measured between group A and B, as well as between group C and D (P > 0.05).
Conclusion:
Sleeve-in-sleeve sCAIS demonstrated higher precision than sleeve-on-drill sCAIS.
