简要总结
Conventional alginate impressions are still a burden to both the patient and the operator especially in extraoral maxillofacial rehabilitations cases. Nowadays face scanners are becoming more popular with their increased accuracy in taking facial scans, facilitating the digital workflow.
This study will be done to investigate the accuracy of three different face scanning techniques; stationary, handheld and mobile application techniques.
A number of sixty volunteers will be recruited. Conventional facial impressions will be made for each participant and the resulting casts will be desktop scanned to act as the control group. Three face scanning techniques will be used for each participant; stationary (Ray face scanner), handheld (Shining 3d face scanner) and mobile phone applications (Heges; Maerk Simonik). The STL files will be compared to that of the control group for comparison of accuracy in the terms of Trueness and Precision.
详细描述
• Study Setting: The study will be conducted in the Oral and Maxillofacial Prosthodontics Department.
• Sample Size Calculation: Sixty participants will be selected to share in this study from the outpatient clinic of Prosthodontics Department, Faculty of Dentistry, Ain-Shams University. G power program (3. 1) was used for calculations of sample size. Statistical calculator was based on 95% confidence interval and power of the study 80% with α error 5%.
According to a previous study done by Nuytens et al. " Trueness and precision of a handheld, a desktop and a mobile 3D face scanning system: An in vitro study"
• Eligibility criteria: Inclusion Criteria Those who completed growth. Exclusion Criteria
1- Men with beards. 2- Those with maxillofacial deformity Justification for Exclusions (Those will interfere with the scan)
