Abstract

Purpose: To evaluate the effects of arch size and implant angulation on the accuracy of implant impressions. Materials and Methods: Four different resin models (small and large) of edentulous maxilla were fabricated and four implants were inserted (Blossom®, O 4.75 × 10 mm) in each model. Implants were either parallel or angled 25° buccally. Forty working casts (small parallel, small angled, large parallel, and large angled) were fabricated in dental stone (n=10). For each implant, linear and angular displacements were measured using a coordinate-measuring machine (CMM) and mean values were analyzed by univariate analysis (α = 0.05). Results: Arch size did not affect the linear or angular displacement (P > .05). However, the implant angulation had a marked influence on the linear displacement (P < .05). The largest linear displacement occurred in implant no. 4 of angled small groups. Conclusion: Regardless of arch size, linear and angular accuracy of implant impression varied with the implant angulation. © 2021 by Dennis Barber Ltd. All rights reserved.
