Implant- and Tooth-Supported Fixed Prostheses Using a High-Performance Polymer (Pekkton) Framework.

Area of Science:

• Dental materials science
• Biomaterials engineering
• Prosthodontics

Background:

• Implant-supported prostheses are crucial for restoring masticatory function and quality of life.
• Traditional frameworks utilize metal casting or milling of titanium or zirconia.
• Nonmetal polymer materials are emerging as potential alternatives for prosthesis frameworks.

Observation:

• Polyetherketoneketone (PEKK) is a high-performance polymer recently introduced to dentistry.
• This case report details the fabrication of implant- and tooth-supported fixed prostheses using a PEKK framework (Pekkton).
• The prostheses were designed for a fully edentulous maxilla and a partially edentulous mandible.

Findings:

• The study successfully utilized a novel high-performance polymer framework for complex dental restorations.
• The PEKK material demonstrated potential for creating durable and functional implant-supported prostheses.
• This approach offers a nonmetal framework option for both fully and partially edentulous patients.

Implications:

• PEKK frameworks may provide a viable alternative to traditional metal or ceramic materials in implant dentistry.
• The use of such polymers could expand treatment options and potentially improve patient outcomes.
• Further research into the long-term performance and clinical efficacy of PEKK in prosthodontics is warranted.
