Abstract
Introduction: Dimensional accuracy of impressions for the fabrication of implant-supported prosthetic restorations has been a concern for clinicians. The material used for splinting of implants in the open tray technique can affect the passive fit between the abutments.
Aim of Works: This study sought to assess the dimensional accuracy of splinted open tray implant impression technique with four commonly used splinting materials.
Methods: In this in vitro, experimental study, four internal hex implants with 4mm diameter and 11.5mm length were placed in a mandibular model. Two implants were placed parallel in the right and left quadrants with 10 mm distance from the midline. The third implant was placed with 15° and the fourth with 25° angle with 10 mm distance from each other and fixed with cyanoacrylate glue. Open tray copings were splinted using Duralay (Reliance), Pattern Resin, Duralay (Ariadent) and Futar D. Special trays were fabricated for each group and impressions were taken using Monopren addition silicon. Impressions were poured with type IV dental stone. Three linear distances including the distance between the most anterior and most posterior analog (A1), distance between the internal margin of anterior analogs in the right and left quadrants (A2) and distance between the external margins of the posterior analogs in the right and left quadrants (A3) were measured on the reference model and on the final cast with eight repetitions using a coordinate measuring machine (CMM). Dimensional changes were assessed by ANOVA and post hoc Tukey’s test.
Results: The maximum dimensional change was 0.7% in A1 (P = 0.6), 0.5% in A2 (P = 0.2) and 0.8% in A3 (P = 0.8). Dimensional accuracy of impressions was not significantly different among the four materials (P > 0.05).
Conclusion: The four splinting materials used in this study for the open tray impression technique were not significantly different in terms of the accuracy of impressions. Pattern Resin showed slightly superior accuracy.
