Tomographic Planning of Dental Implants Using a Smartphone: Linear Measurements and Implant Selection-A Cross-Sectional Study.

Abstract

This study assessed the accuracy of linear measurements and dental implant selection performed in a smartphone application compared to a computer software. Forty-four DICOM files from partially edentulous patients in the posterior region of the mandible were evaluated by three trained and calibrated examiners. Images were analyzed using three visualization methods: cross-sectional view (CScr) and coronal (CSco) plane using the CS 3D Imaging software, and coronal (DRco) plane using the DroidRender smartphone application. For the purpose of standardization, measurements of bone width and height were taken in the edentulous posterior region of the mandible, 10 mm posterior to the mental foramen. Dental implant selection was made according to Straumann® Standard implant catalog 2022/2023. Linear measurements were compared using the ANOVA test for repeated measurements and implant selection was compared using the Friedman test. Statistical analysis was performed using the SPSS software, considering a significance level of 5%. Linear measurements showed a statistically significant difference for bone width (p = 0.030), but not for height (p = 0.685). The choice of implant was not influenced by the visualization method (p = 0.614). It is possible to suggest the use of smartphone applications as an additional diagnostic tool for DICOM evaluation and dental implant planning in the posterior region of the mandible. Smartphone applications allow an assessment not limited to 2D images or to static environments. Therefore, information exchange and diagnostic opinion in emergency situations may be facilitated.
