Bite mark analysis methods have been increasingly questioned due to concerns about their scientific reliability. This study focuses on the methodological evaluation of an overlay generation protocol independently of biological trace interpretation.\n\nThirty adult participants requiring routine dental care involving intraoral scanning will be included. A digital impression of the maxillary dentition will be obtained using a standard intraoral scanner, which is a non-invasive and routine clinical procedure.\n\nDigital dental models will be anonymized and processed using dedicated software to generate overlays. Four operators with different levels of expertise will independently perform the overlay procedure at two separate time points.\n\nThe study will assess intra-operator repeatability and inter-operator reproducibility using quantitative 2D and 3D metrics. The objective is to determine the variability of the protocol and to contribute to the standardization and reliability of overlay-based analyses in forensic dentistry.",[25,26],"Forensic Dentistry","Bite Mark Analysis","RECRUITING","2026-06-23",{"date":30,"type":31},"2026-06-24","ACTUAL",{"date":33,"type":31},"2026-04-01",{"date":35,"type":21},"2027-06",{"name":37,"class":38},"Nantes University Hospital","OTHER"]
