Accuracy in the Plaster Model of Total Prosthetic Plates in Three Different Manufacturing Methods: In Vitro Study
Year: 2025
Type: article
Abstract: Background: Technological progress in the field of prosthetic dentistry has changed the workflow, optimizing times and increasing the possible choices of prosthetic rehabilitation. Methods: The adaptability of three resin plates to the plaster model was evaluated by visual evaluation and by filling out a questionnaire in which two areas present in three silicone impressions obtained with three different construction methods were selected, including the traditional method, CAD/CAM method for milling, and CAD/CAM method for addition. Results: The results showed that although silicone 3 obtained with the additive method had better performances in the selected areas, the p-value of 0.735 was >0.05, and therefore there are no statistically significant differences between the different silicone impressions. Furthermore, a poor agreement between the evaluators was found (k 0.184). Conclusions: This work conducted in vitro highlights an important aspect of the choice of material used for impressions in cases of prosthetic relining. More in-depth studies with larger samples and objective measurement methods will be needed to compare fit data across different prosthetic construction modalities.
