Summary
This study presents a digital workflow for establishing jaw relationships in patients with terminal dentition. This method simplifies treatment by enabling simultaneous extraction and implant surgery, reducing costs and chair time.
Area of Science:
- Dentistry
- Digital Dentistry
- Oral Implantology
Background:
- Establishing a reliable jaw relationship is difficult for patients with terminal dentition and occlusal interference.
- Long-term partial edentulism complicates pre-extraction jaw relation determination.
Purpose of the Study:
- To introduce a digital workflow for establishing and transferring jaw relationships in patients with terminal dentition.
- To streamline the treatment process for full-mouth rehabilitation with dental implants.
Main Methods:
- Utilized a 3D-printed custom gothic arch tracer for centric relation registration.
- Integrated facial scans for virtual mandibular rotation to determine vertical dimension.
- Transferred the pre-operative jaw relationship postoperatively using bone fiducials.
Main Results:
- Eliminated the need for complete denture fabrication to establish jaw relationships.
- Enabled simultaneous extraction and implant surgery.
- Significantly reduced overall treatment cost and chairside time.
Conclusions:
- The digital workflow effectively establishes and transfers jaw relationships for full-mouth rehabilitation.
- This technique offers a more efficient and cost-effective approach for patients requiring dental implants after extractions.
