Summary
A new laser scanner and software enable accurate computer-aided design and manufacturing of titanium dental frameworks. This technology shows high implant and prosthesis survival rates for restoring edentulous arches.
Area of Science:
- Biomaterials Engineering
- Dental Implantology
- Computer-Aided Technology
Background:
- Restoring edentulous arches with dental implants requires precise fabrication of prosthetics.
- Computer-aided design and computer-aided manufacturing (CAD/CAM) have advanced prosthetic fabrication.
Purpose of the Study:
- To introduce a novel noncontact laser probe scanner and associated software.
- To evaluate the outcomes of CAD/CAM titanium frameworks fabricated using this new system.
Main Methods:
- Forty implants were placed in seven patients using a 1-stage protocol and implant planning software.
- Complete-arch, implant-supported titanium frameworks were milled using the new CAD/CAM software and scanner.
- Patients were followed for 18 months to assess implant survival, prosthesis success, framework fit, and marginal bone levels.
Main Results:
- The implant survival rate was 97.5% with 0.4 mm marginal bone loss after 18 months.
- The prosthesis success rate was 100%, with no replacements needed.
- Titanium frameworks demonstrated accurate fit.
Conclusions:
- Titanium frameworks fabricated with the novel software and laser scanner system exhibit accurate fit.
- This CAD/CAM approach presents a viable option for restoring edentulous arches with dental implants.
