研究概览
简要总结
the relative accuracy of different intraoral scanner types specifically for capturing the complex morphology of edentulous arches, including peripheral borders and mobile tissues, remains an area of investigation, with conflicting reports in the literature.
The purpose of this study is to compare the accuracy of different intraoral scanners with a laboratory scanner for digitizing impressions of edentulous mandible.
Completely edentulous patients will be gathered; final impressions will be taken for them using zinc oxide & eugenol impression material then they will be scanned with intra oral and extra oral scanners for indirect digitalization.
Scans will be superimposed and compared using a software program for analysis for accuracy in the form of trueness
详细描述
completely edentulous patients will be recruited.
Study procedures:
Custom trays will be fabricated and checked for extension, and then definitive impressions will be made with type-1 low fusing impression compound (Tracing sticks; Kemdent, UK) for border molding and zinc oxide eugenol impression paste (Cavex Holland B.N) for the impression. Reference markers will be placed on the impressions in anterior and posterior ridge areas.
The indirect digitalization of impressions will be made with two different Intraoral scanning devices and a laboratory scanner.

研究组 & 干预措施
Digital impression of the mandibular edentulous arch
Digital impression of the mandibular edentulous arch will be made by MEDIT i600 scanner (Medit Corp. Seoul, South Korea) followed by another digital impression of the same arch using Aoralscan scanner (Shining 3D Tech. Co., Ltd. Hangzhou, China). Both impressions will be compared to each other in terms of trueness.
干预措施: Digital impression of the mandibular edentulous arch (Other)
结局指标
主要结局
trueness assessment of impression techniques for mandibular edentulous arches
时间窗: 3 months
Assessment of trueness of Digital impression of the mandibular edentulous arch using intra oral scanner will be made by MEDIT i600 scanner (Medit Corp. Seoul, South Korea) followed by another digital impression of the same arch using Aoralscan scanner (Shining 3D Tech. Co., Ltd. Hangzhou, China). Both impressions will be compared to each other in terms of trueness in relation to desktop scanner. Root mean square of trueness in m.m will be reported.
