摘要
Purpose: To evaluate the influence of implant scanbody (ISB) material, position and operator on the accuracy of a confocal microscopy intraoral scanning (IOS) for complete-arch implant impression. Methods: An edentulous maxillary model with 6 internal hexagonal connection analogues was scanned with an extraoral optical scanner to achieve a reference file. Three ISBs made of different materials (polyetheretherketone (Pk), titanium (T) and Pk with a titanium base (Pkt)) were scanned with IOS by 3 operators. The resulting 45 test files were aligned to the reference file with a best fit algorithm. Linear (Delta X, Delta Y and Delta Z-axis) and angular deviations (Delta ANGLE) were assessed. Absolute values of the linear discrepancies were summed up to obtain a global measure of linear absolute error (Delta ASS). Influence of ISB material, position and operator was statistically assessed using the mixed general linear model. Results: At multivariate analysis, when Delta ASS was considered as response variable, it was identified a significant influence of material (p <0.0001) and position (p= 0.0009) while no significant operator effect was detected. When Delta ANGLE was considered as response variable, material and position significantly influenced the expected Delta ANGLE (p =0.0232 and p <0.0001) and no operator effect was identified. Conclusions: The investigated IOS for complete-arch digital impression was influenced by the ISB material with peek reporting the best results on both linear and angular measurements followed by titanium, peek-titanium resulting as the less accurate. Implant angulation affected significantly the linear deviations while implant position the angular deviations. Operator did not show any significant effect on the IOS accuracy.
