Comparative evaluation of the accuracy of implant position reproduction obtained using analog and digital impression methods an in vitro study
Journal Title: BOHR International Journal of Current Research in Dentistry - Year 2024, Vol 3, Issue 1
Abstract
Purpose of the study: To compare the accuracy of implant location reproduction utilizing digital and analog impression techniques. Materials and methods: Two implant analogs were positioned bilaterally in the 2nd premolar area at the crestal and 3 mm below the crestal level (subcrestal) to create a Maxillary Dentulous Master model. From the master model, ten analog implant impressions were created, and working castings with crestal (GROUP IA) and subcrestal (GROUP IB) implant analogs were produced. Using an intraoral scanner and STL files created, ten digital implant impressions were created from the master model with crestal (GROUP IIA) and subcrestal (GROUP IIB) implant analogs. The master model, or control, and the 10 working castings were digitalized and exported as STL files. By superimposing the STL files from each and every group onto the master model STL file, accuracy was evaluated. Using a gradient that was color-coded, the 3D deviations have been calculated at 10 different sites. The Mann– Whitney U test has been utilized statistically to assess the study’s outcomes. Results: There were no discernible variations in 3D deviations among GROUPS IA and IB, GROUPS IIA and IIB, and GROUPS IB and IIB. Only the distal contact area of the crestally implanted implant in the digital impressions showed statistically significant variations among GROUPS IA and IIA (P = 0.026), and this difference was judged to be within a threshold level that is clinically acceptable. Conclusion: Both digital and analog implant impression techniques can be used for single-tooth implant impression making.
