Implant Supported Hybrid Prostheses Using a High-Performance Polymer (Pekkton) Framework: Case Report

Implant Supported Hybrid Prostheses Using a High-Performance Polymer (Pekkton) Framework: Case Report Mehmet Akça1,Stefani Eken1,Gülsüm Sayın Özel1 1-Istanbul Medipol University, Abstract Purpose: Polyetherketoneketone (PEKK), is a high-performance polymer, was recently introduced in the dental field with potentially wide-ranging applications. These case reports describe hybrid prostheses supported with tilted implants systems using a high performance and polymer (Pekkton) framework for a fully edentulous maxilla and mandible. Material methods: In these case reports 3 patients were reported for pekkton substructure hybrid prostheses. One of them pekkton framework design was different as facet design two of them were toronto design. Tilted implant systems were applied for the lower and upper jaws due to vertical and horizontal bone losses in our patients and hybrid prostheses solutions were applied with a pekkton infrastructure to provide the missing lip support and profile. Case 1(56 year old woman) and case 2(52 year old man),were rehabilitated with, maxillary and mandibular hybrid prostheses with pekkton substructure-toronto-design and zirconia crowns.Case 3 (32 year old man) was rehabilitated with, maxillary and mandibular hybrid prosthesis with pekkton substructure facet design and acrylic artificial teeth and laboratory composite. Results: Clinical and radiological findings were satisfactory for Case 1 and Case 2. After 3 years of follow-up, functional, phonetic or aesthetic problems were not detected in the restorations. In case 3, which was designed by applying different production methods, recurrent laboratory composite fractures observed after 8 months. Conclusion: Implant-supported hybrid prostheses made by pekkton substructure may be a reliable alternative treatment procedure in cases where metal-supported-porcelain or zirconia-supported- porcelain fixed restoration cannot provide the patient's aesthetic, phonetic, oral hygiene and oral comfort.
