Abstract

The fabrication of implant surgical guides through stereolithographic 3D printing has become a staple in dental implant guided surgery over the last couple decades. These surgical guides have typically utilized metal sleeves to assist in guidance of the drills during osteotome preparation. The metal sleeves can be costly and potentially cause deviations if improperly placed during post-processing of the guide. This research explored a novel method for the utilization of sleeve-free surgical guides by comparing the dimensional and angulational deviations between the implant guides with and without a metal sleeve. To achieve this goal, two separate aims were pursued. Our first aim analyzed the implant deviation differences created by a single guide with a metal sleeve and one guide without. Ten implants were placed in ten dental models per each type of surgical guide and the deviations were measured in the mesial, apical, cervical, and angulational dimensions. The second aim of this study was to analyze any angulational and positional differences produced when the sample size of the surgical guides was increased for the two different groups to produce a guide to cast ratio of 1:1. This was achieved by analyzing the same two surgical guide designs and dimensional parameters but increasing the number of surgical guides produced to yield one guide per dental model with a total of 10 pairs of guide-cast per group. The results provided no significant difference in implant deviations between the guides with and without a metal sleeve except for the mesial dimension in the second aim. This study concluded that the surgical guide without a metal sleeve demonstrates similar accuracy and precision to the surgical guide with a metal sleeve. Thus, metal sleeves may not be required for accurate implant placement.
