Clinical accuracy between planned and placed posterior implant position of two static implant planning software programs in inexperienced operators 

Objective: This study aimed to evaluate and examine the difference in posterior implant positioning between the planned and placed positions when inexperienced operators used two static implant planning software packages following a fully guided implant surgery protocol in the clinical field. Materials and methods: Twenty-four patients who needed single posterior implant placement were randomly divided into two groups based on the used implant planning software (group 1, coDiagnostiX, n=12; group 2, Implant Studio, n=12). The dataset of the placed implant position, generated from digitizing the implant impression, was superimposed on the planned implant position. The number of horizontal, angular, and vertical deviations of the placed implants were measured for each software package and statistically analyzed. Results: Group 1 (coDiagnostiX) presented with a mean horizontal deviation at the entry point (DE) of 1.07 ± 0.36 mm, mean angular deviation (DA) of 3.52 ± 1.64, and mean depth deviation (DD) of −0.71 ± 0.29 mm, while the mean DE, mean DA, and mean DD in group 2 (Implant Studio) were 0.97 ± 0.33 mm, 3.77 ± 2.16, and −0.84 ± 0.30 mm respectively. Statistically, no significant differences were found between groups 1 and 2 for all results reported above (P>0.05) Conclusions: No significant differences were found in the accuracy of implant position between coDiagnostiX and Implant Studio programs following posterior implant placement performed by inexperienced operators.
