Abstract

Impression techniques are continuously evolving. New technologies such as photogrammetry impression techniques have long been considered a viable alternative to conventional impressions. The aim of this study was to compare the level of passive fit obtained with photogrammetry with the level achieved using conventional interventions relying on addition silicone open trays and splinting impression techniques. A randomized, controlled, single-center trial was conducted which included patients who were prescribed 5 or more implants. The PICDental® system was used to determine the spatially implant positions in the photogrammetry group. The primary outcome of the study was the accuracy of the methods. The secondary outcome was the precision of the two types of interventions, as defined by number of implants, intervention times, number of healing cap or attachment connections/disconnections, and radiation exposure times. Twenty-two patients who fulfilled the inclusion criteria were enrolled in the study. These represented 24 clinical cases. There was a strongly significant difference in mean fit between the two study groups (conventional vs photogrammetry) in favor of photogrammetry (p < 0.01). In cases of more than 6 implants, passive fits were not achieved in any of the cases. There was a mean intervention time of 36.66 minutes in conventional cases in contrast a mean value of 13.23 min for the photogrammetry group, a significant difference (p < 0.001). A mean radiation time of 40.54 s was observed in the group who underwent conventional impressions, and a mean value of 13.20s in all cases where photogrammetry was used, a significant difference (p < 0.001). In summary, the results of this study have demonstrated the superiority of photogrammetric impression techniques over conventional ones, in terms of passive fit, radiation exposure times, intervention times, and the number of connections and disconnections required per implant.
