Abstract

Purpose: To compare the 3D accuracy of copy dentures fabricated using an IOS (IOS copy denture) to that of copy dentures fabricated using the conventional method (conventional copy denture).

Materials and methods: Maxillary and mandibular complete dentures were fabricated and scanned using a high-precision dental laboratory scanner to obtain data (basic data). Optical impressions of the dentures were recorded with the IOS to obtain data (IOS reference dentures). The IOS copy denture was fabricated using a 3D printer after configuring the data using the software. The conventional copy dentures were fabricated by making impressions of the complete dentures and pouring the room-temperature curing resin into them. The IOS copy dentures and conventional copy dentures were scanned using a high-precision dental laboratory scanner to obtain data. The data obtained were imported into 3D analysis software, and the IOS reference denture, IOS copy denture, and conventional copy denture data were each superimposed on the basic data for 3D evaluation by color mapping and calculation of the concordance rate.

Results: Statistically significant differences in the concordance rates were observed between the IOS reference dentures and IOS copy dentures and between IOS copy dentures and conventional copy dentures (P < .05), but not between maxillary and mandibular complete dentures (P > .05).

Conclusion: The IOS copy dentures demonstrated greater accuracy than the conventional copy dentures.

使用口腔内扫描和3D打印机与传统复制义齿技术制作种植支持复制覆盖义齿的准确性:比较研究。

目的:比较使用IOS (IOS复制义齿)制作的复制义齿与使用常规方法制作的复制义齿的3D精度。材料与方法:制作上颌、下颌全口义齿，使用高精度口腔实验室扫描仪进行扫描，获取数据(基础数据)。用IOS记录义齿的光学印象，获得数据(IOS参考义齿)。使用软件配置数据后，使用3D打印机制作IOS复制义齿。传统的复制义齿是将全口义齿印模后注入室温固化树脂制备的。采用高精度口腔实验室扫描仪对IOS复制义齿和常规复制义齿进行扫描，获取数据。将获得的数据导入三维分析软件，将IOS参考义齿、IOS复制义齿和常规复制义齿数据分别叠加在基础数据上，通过颜色映射和计算一致性率进行三维评价。结果:IOS参考义齿与IOS复制义齿、IOS复制义齿与常规复制义齿的吻合率差异有统计学意义(P < 0.05)，上颌与下颌全口义齿的吻合率差异无统计学意义(P > 0.05)。结论:IOS仿造义齿比传统仿造义齿具有更高的准确性。

期刊介绍： Edited by Steven E. Eckert, DDS, MS ISSN (Print): 0882-2786 ISSN (Online): 1942-4434 This highly regarded, often-cited journal integrates clinical and scientific data to improve methods and results of oral and maxillofacial implant therapy. It presents pioneering research, technology, clinical applications, reviews of the literature, seminal studies, emerging technology, position papers, and consensus studies, as well as the many clinical and therapeutic innovations that ensue as a result of these efforts. The editorial board is composed of recognized opinion leaders in their respective areas of expertise and reflects the international reach of the journal. Under their leadership, JOMI maintains its strong scientific integrity while expanding its influence within the field of implant dentistry. JOMI’s popular regular feature "Thematic Abstract Review" presents a review of abstracts of recently published articles on a specific topical area of interest each issue.
