Summary
This study introduces a photogrammetry system for precise dental implant positioning, enabling accurate prosthetic rehabilitation for patients with missing teeth. The technique proved fast, simple, and comfortable, ensuring optimal implant fit and healthy peri-implant tissues.
Area of Science:
- Dental Implantology
- Photogrammetry
- Prosthetic Rehabilitation
Background:
- Accurate registration of multiple dental implant positions is crucial for successful prosthetic rehabilitation.
- Traditional methods can be time-consuming and may lack precision.
Observation:
- A novel photogrammetry-based system (PICcamera®) was utilized to register the positions of three dental implants.
- The system captured 150 images in under 60 seconds, generating a vector-form file of implant positions.
- Alginate impressions and subsequent scanning provided soft tissue data for CAD/CAM fabrication.
Findings:
- The photogrammetry technique facilitated the creation of a prosthesis with optimal passive fit, verified by clinical tests.
- Peri-implant tissues remained healthy with no marginal bone loss observed 12 months post-loading.
Implications:
- This photogrammetry system offers an accurate, fast, and simple method for multiple dental implant registration.
- It enhances the precision of prosthetic treatment, improving patient outcomes and comfort.
- The technique is particularly beneficial for rehabilitating complex cases like posterior maxillary edentulism.
