Abstract

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.

生物功能修复系统设计的下颌全口义齿模型修正区分析。

目的：利用数字扫描技术，分析生物功能修复系统（BPS）设计的下颌全口义齿模型与初始模型相比的修复区域和程度。方法：选取20例需要使用BPS进行下颌修复的无牙患者作为研究对象。获得了无牙下颌骨的初始和最终石膏模型的数字扫描。利用Geomagic Warp软件对模型进行了校正、配准和修正区分析。结果：下颌舌骨后窝、颌下腺区、唇前庭三个特定区域差异有统计学意义（p < 0.05）。相比之下，后磨牙垫面积差异极小（p < 0.05）。总的来说，最终模型与初始模型有显著差异（p < 0.05），下颌舌骨后窝的差异最大，后磨牙垫区域的差异最小。结论：与初始模型相比，使用BPS构建的最终下颌全口义齿模型在咬合压力下表现粘膜运动、形状和定位的准确性更高。下颌舌骨后窝、下颌下腺区和唇前庭对粘膜运动边界的描绘增强，有助于更精确的功能表征。

期刊介绍： Therapeutics and Clinical Risk Management is an international, peer-reviewed journal of clinical therapeutics and risk management, focusing on concise rapid reporting of clinical studies in all therapeutic areas, outcomes, safety, and programs for the effective, safe, and sustained use of medicines, therapeutic and surgical interventions in all clinical areas. The journal welcomes submissions covering original research, clinical and epidemiological studies, reviews, guidelines, expert opinion and commentary. The journal will consider case reports but only if they make a valuable and original contribution to the literature. As of 18th March 2019, Therapeutics and Clinical Risk Management will no longer consider meta-analyses for publication. The journal does not accept study protocols, animal-based or cell line-based studies.
