Radiographic dental implants recognition for geographic evaluation in human identification

Area of Science:

• Forensic Odontology
• Prosthodontics
• Radiology

Background:

• Dental implants are common for prosthetic rehabilitation in Italy.
• A wide variety of implant systems exist, complicating identification.
• Forensic casework requires methods to identify implants in unidentified individuals.

Purpose of the Study:

• To create a catalogue of digital radiographic images of dental implants available in Italy.
• To establish identification criteria for dental implants using radiography.
• To aid forensic odontologists and prosthodontists in implant recognition.

Main Methods:

• Italian dental implant manufacturers provided specimen implants.
• Digital radiographs were taken at various horizontal and vertical angulations.
• 15 images per implant were analyzed for unique identification features.

Main Results:

• Specific radiographic features were identified for implant recognition.
• Radiographs taken between -10º and +10º vertical inclination are most useful for definite identification.
• The study provides a survey of commercially distributed dental implants in Italy via digital radiography.

Conclusions:

• This radiographic image catalogue serves as a valuable tool for forensic identification.
• The methodology can be expanded for evaluating international dental implant manufacturers.
• Accurate implant identification supports forensic investigations and prosthodontic treatment planning.
