Summary
A new digital workflow enables the fabrication of polyetherketoneketone (PEKK) periodontal splints. These splints demonstrate antibacterial properties and maintain oral hygiene effectively over a 2-year period.
Area of Science:
- Biomaterials Science
- Dental Technology
- Periodontology
Background:
- Periodontal splinting is crucial for stabilizing teeth following treatment.
- Traditional splint fabrication can be time-consuming and may present challenges in achieving optimal fit.
- Advancements in digital technology offer potential for improved dental device fabrication.
Purpose of the Study:
- To describe a digital workflow for fabricating a polyetherketoneketone (PEKK) periodontal splint.
- To evaluate the clinical performance and patient outcomes of PEKK periodontal splints.
- To assess the impact of PEKK splints on oral hygiene and periodontal maintenance.
Main Methods:
- Development of a digital workflow integrating CAD/CAM for PEKK splint fabrication.
- Clinical application of the fabricated PEKK periodontal splints in patients.
- Long-term follow-up (2 years) to monitor oral hygiene, periodontal health, and adverse effects.
Main Results:
- The digital workflow successfully produced precise PEKK periodontal splints.
- PEKK material exhibited favorable antibacterial properties in the oral environment.
- Patients maintained good oral hygiene and periodontal health throughout the 2-year follow-up.
- No adverse effects related to the splints were reported.
Conclusions:
- A digital fabrication workflow for PEKK periodontal splints is feasible and efficient.
- PEKK splints offer a promising solution for periodontal stabilization due to their material properties.
- Digital technology enhances the precision and clinical outcomes of periodontal splinting.
