Objective: This study aimed to analyze the regions and extent of modifications made to the final mandibular complete denture model designed using the bio-functional prosthetic system (BPS), compared to the initial model, utilizing digital scanning technology.
Methods: Twenty individuals with edentulism requiring mandibular restoration using BPS were included in the study. Digital scans of the initial and final gypsum models of the edentulous mandible were obtained. The models were aligned, registered, and analyzed for modification zones using Geomagic Warp software.
Results: Statistically significant differences were observed in three specific regions: the posterior fossa of the mylohyoid, the submandibular gland region, and the labial vestibule (p < 0.05). In contrast, differences in the posterior molar pad area were minimal (p > 0.05). Overall, the final model exhibited significant deviations from the initial model (p < 0.05), with the greatest variation observed in the posterior fossa of the mylohyoid and the least variation in the posterior molar pad area.
Conclusion: The final mandibular complete denture model, constructed using BPS, demonstrates improved accuracy in representing mucosal movement, shape, and positioning under occlusal pressure compared to the initial model. The posterior fossa of the mylohyoid, submandibular gland region, and labial vestibule exhibited enhanced delineation of mucosal movement boundaries, contributing to a more precise functional representation.
