Design and Development of a Transillumination-based Intraoral Imaging Probe for Dental Implant Localization

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Dental Technology

Background:

• Conventional dental imaging like CT scans and X-rays pose risks due to ionizing radiation exposure.
• Accurate visualization of dental implants post-healing, especially when covered by gums, is crucial for assessment.

Purpose of the Study:

• To design and develop a novel transillumination-based intraoral imaging probe.
• To provide a radiation-free alternative for visualizing dental implants after gum healing.

Main Methods:

• Development of a transillumination-based intraoral imaging probe.
• Testing the probe on Polydimethylsiloxane (PDMS) phantoms with embedded metallic screws simulating dental implants.
• Quantitative analysis of intensity profiles for accuracy validation.

Main Results:

• The imaging probe successfully visualized key features of the simulated dental implant.
• Accuracy in predicting implant diameter was validated with a low error rate of 5.29%.

Conclusions:

• The transillumination imaging probe presents a promising radiation-free method for dental implant visualization.
• This technology offers a safer approach for post-healing dental implant assessment, reducing patient exposure to ionizing radiation.
