EXPERIENCE OF USING PHOTOGRAMMETRY METHOD IN MODERN IMPLANTOLOGICAL PRACTICE (LITERATURE REVIEW)

Abstract

Introduction. Analysis of the current evidence base would be useful regarding the accuracy (trueness and precision) of digital impressions obtained with the photogrammetry method for the dental implants position registration, while also it is well reasoned to provide an assessment of the results presented at the clinical studies, in vitro studies, systematic reviews and consensus reports regarding the significance and feasibility of implementing such approach into the comprehensive digital protocol of complex dental rehabilitation of edentulous jaws with full-arch implant-supported fixed dentures. Objective. To analyze the data on the effectiveness and accuracy of the photogrammetry method within dental practice with the aim to register the positions of multiple dental implants during the rehabilitation of patients with complete aedentia. Methods. Literature sources related to the research objective were searched within the PubMed Central database (https://www. ncbi.nlm.nih.gov/pmc/) using the following search query: "("photogrammetry"[MeSH Terms] OR "photogrammetry"[All Fields]) AND ("dental implants"[MeSH Terms] OR ("dental"[All Fields] AND "implants"[All Fields]) OR "dental implants"[All Fields])", as well as using the Google Scholar service and the keywords "photogrammetry" and "dental implants" while taking into account features of advanced search. Only scientific articles published in English were considered for the analysis, while the depth of the search was 5 years (2018–2023). Results. Out of the 20 publications selected for detailed analysis, 4 were presented in the form of systematic reviews, 2 in the form of comparative clinical studies, 2 in the form of clinical reports, 1 in the form of technical report, 10 in the form of laboratory studies, and 1 in the form of prospective study. According to the data obtained after literature review, it can be summarized that the photogrammetry method provides clinically acceptable results of digital registration for dental implants’ position, however, the comparative accuracy of the method, represented in the form of trueness and precision regarding the ground truth position of intraosseous fixtures, differs according to the various studies’ data. Parameters of trueness and precision of the photogrammetry method used for digital registration of dental implants’ position are higher due to the results of laboratory studies compare to the results of clinical studies. Conclusions. Taking into account the conclusions of the available systematic reviews it may be resumed that accuracy of the photogrammetry method is, at least, comparable to the accuracy of the intraoral scanning method, and in some clinical cases it exceeds the efficiency of the latter for registering the position of implants during the rehabilitation of edentulous jaws with fullarch implant-supported fixed dentures. The photogrammetry method does not exclude the need to use an intraoral scanner during the implementation of digital protocol for the edentulous patients’ rehabilitation with full-arch implant-supported fixed dentures, since it does not provide opportunities for registering the condition of soft tissues in the peri-implant area, but it is characterized by pronounced advantages in cases of edentulous jaws’ rehabilitation with prosthetically compromised positions of placed implants.
