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.
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 ( < 0.05).
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 ( < 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 ( > 0.05).
Sleeve-in-sleeve sCAIS demonstrated higher precision than sleeve-on-drill sCAIS.
背景/目的：有多种静态计算机辅助种植手术（sCAIS）设计可供临床医生使用，以实现种植体的正确植入位置。然而，尚无任何研究单独探讨这些设计，以评估套筒内套筒或套筒在钻头上的设计是否能提供最精确的种植体位置。本研究的目的是调查采用套筒内套筒和套筒在钻头上的静态计算机辅助种植手术（sCAIS）设计进行种植体植入的精度。
制作了32个模拟双侧第一前磨牙缺失患者的模型。每组分配8个模型（16颗种植体）：A组、B组和C组分别代表套筒高度为2mm、4mm和6mm的套筒内套筒设计。D组代表套筒高度为4mm的一体化套筒在钻头上的设计。测量种植体平台、根尖处的三维偏差和角度偏差。使用单因素方差分析对数据进行分析（P<0.05）。
平台处的总体偏差范围为0.40±0.14mm（A组）至0.73±1.54mm（C组），根尖处为0.46±0.16mm（A组）至1.07±0.37mm（C组），角度偏差范围为0.86±0.89°（A组）至3.40±1.29°（C组）。A组和B组的偏差明显小于C组和D组（P<0.05）。A组和B组之间以及C组和D组之间在所有测量参数上均无统计学显著差异（P>0.05）。
套筒内套筒sCAIS比套筒在钻头上的sCAIS具有更高的精度。
