Abstract

Background: Prosthetically driven implant surgery provides a higher level of precision in the placement of dental implants and leads to more predictable outcomes in prosthetic results when compared to implant surgery without guidance. Aim: To evaluate and compare the accuracy of implant placement when utilizing surgical guides that are 3D printed through Stereolithography (SLA) and Digital Light Processing (DLP) techniques. Materials and Methods: Eighteen epoxy resin models with a missing mandibular first molar were prepared. The positioning of the implant was planned virtually using 3D planning software. Total of nine surgical guides were manufactured using an SLA 3D printer and another nine guides were manufactured using a DLP 3D printer. Total of 18 dental implants (5.5×11 mm) were placed using tooth supported surgical guides. Dental implants were digitally scanned using scan body and the differences between the planned and placed position of implants in terms of point of entry, apical point and angular deviation were assessed for both groups. For comparison, the Mann-Whitney U test was used (P ≤0.05). Results: Statistically significant difference was observed between SLA and DLP in relation to the deviation at entry point of the implants (P=0.021) and deviation at apical point (P
