dc.description.abstractObjectives: To evaluate the positional accuracy of implant analogs in biobased model resin by comparing them to that of implant analogs in model resin casts and conventional analogs in dental stone casts. Methods: Polyvinylsiloxane impressions of a partially edentulous mandibular model with a single implant were made and poured in type IV dental stone. The same model was also digitized with an intraoral scanner and additively manufactured implant casts were fabricated in biobased model resin (FotoDent biobased model) and model resin (FotoDent model 2 beige -opaque) ( n = 8). All casts and the model were digitized with a laboratory scanner, and the scan files were imported into a 3 -dimensional analysis software (Geomagic Control X). The linear deviations of 2 standardized points on the scan body used during digitization were automatically calculated on x-, y-, and z-axes. Average deviations were used to define precision, and 1 -way analysis of variance and Tukey HSD tests were used for statistical analyses ( alpha = 0.05). Results: Biobased model resin led to higher deviations than dental stone (all axes, P <= 0.031) and model resin (yaxis, P = 0.015). Biobased model resin resulted in the lowest precision of implant analog position ( P <= 0.049). The difference in the positional accuracy of implant analogs of model resin and stone casts was nonsignificant ( P >= 0.196). Conclusions: Implant analogs in biobased model resin casts mostly had lower positional accuracy, whereas those in model resin and stone casts had similar positional accuracy. Regardless of the material, analogs deviated more towards mesial, while buccal deviations in additively manufactured casts and lingual deviations in stone casts were more prominent.
