“…After scrutinizing its properties, use of PEEK in fixed dental prosthesis is gaining popularity. Majority of the studies conducted till date are in vitro ,[ 3 4 5 6 7 8 9 ] and very few clinical studies[ 10 11 12 ] document the longevity of the restoration and its clinical performances. Although taking into consideration the favorable mechanical properties of PEEK, there is lack of acceptance.…”

Aim: The aim of this study was to evaluate the clinical performance and patient satisfaction of PEEK Crowns. Setting and Design: In-vivo longitudinal pilot study. Materials and Method: 20 PEEK crowns were placed in 20 patients. 11 were placed in the maxilla and 9 were placed in the mandible. All procedural steps were performed by the same operator. The teeth were prepared with a chamfer finish line of 0.8 to 1 mm. The crowns fabricated were luted using resin cement. Using Modified Ryge's Criteria, the crowns were examined for anatomic form, marginal integrity, surface roughness, restoration staining, marginal discoloration and color match at a time interval of 1 week, 1 month, 3 months, 6 months, one year. Patient satisfaction was also evaluated at the same interval using a questionnaire. Statistical Analysis Used: The data collected was evaluated using fisher's exact test. Results: Based on modified Ryge's criteria, almost 90% of the crowns were rated satisfactory. Fracture was registered in only one crown. Slight chipping off was seen in two crowns. No significant difference was seen in any other factors assessed. Slight variation was seen in the periodontal status of 3 patients. Conclusion: Within the limitations of this study the following conclusions were drawn that the PEEK crowns demonstrated by the use of Modified Ryge's Criteria, its capability to produce quality prostheses that were rated satisfactory with a relatively low rate of fracture over the relative mean period of one year.

“…In a Finite Element Analysis (FEA) study, the biomechanical behavior of an implant system utilizing the All-on-Four technique with nickel-chromium and PEEK bars was examined. This study revealed that PEEK bars exhibited the highest peak stresses [81] . Despite the limitations of clinical studies, it has been proposed that hybrid PEEK-acrylic resin prostheses supported by implants for full arch rehabilitation could be a feasible treatment option.…”

“…A recent advancement in the field of PEEK involves the creation of hybrid PEEK-acrylic resin prostheses. These are being used in various dental restorative applications, including full arch implant-supported removable prostheses (with the female part of bars milled from PEEK), full arch implant-supported fixed prostheses, and the all-on-four concept [79][80][81] . In a Finite Element Analysis (FEA) study, the biomechanical behavior of an implant system utilizing the All-on-Four technique with nickel-chromium and PEEK bars was examined.…”

Polyetheretherketone (PEEK) is a thermoplastic polymer that has many potential uses in dentistry. This review aims to summarize the reported applications of PEEK as a prosthetic material, the research conducted in regard to its properties concerning prosthetic applications and the future prospects of PEEK as a provisional or permanent prosthetic material. Original scientific articles published in Medline-Pubmed database were electronically searched. Articles published in English were identified, regardless of the year of publication, using a variety of keywords in combination. The studies relevant to our review were critically analysed and summarized. As a result it was found that due to the favorable mechanical and physical properties of PEEK, it can serve as an appropriate alternative material for various uses in dentistry. However, for further dental applications extensive research and clinical trials are required.

“…In this work, the definitive CAD/CAM bars have been milled in PEEK. This choice is perfectly in tune with the metal-free philosophy, which is growing in digital dentistry; however, clinical studies are still needed to assess the performance and reliability of this material over the medium and long term [41]. In fact, although in this study all implants survived for one year, for a 100% survival rate, it should be noted that complications that were recorded during this study (two fixtures with peri-implantitis in the same patient and two repaired overdentures because of tooth fracture in two different patients) determined a success rate for the implant-prosthetic rehabilitation with overdenture of 80%, at 1 year.…”

Purpose. To present a digital method that combines intraoral and face scanning for the computer-assisted design/computer-assisted manufacturing (CAD/CAM) fabrication of implant-supported bars for maxillary overdentures. Methods. Over a 2-year period, all patients presenting to a private dental clinic with a removable complete denture in the maxilla, seeking rehabilitation with implants, were considered for inclusion in this study. Inclusion criteria were fully edentulous maxilla, functional problems with the preexisting denture, opposing dentition, and sufficient bone volume to insert four implants. Exclusion criteria were age<55 years, need for bone augmentation, uncompensated diabetes mellitus, immunocompromised status, radio- and/or chemotherapy, and previous treatment with oral and/or intravenous aminobisphosphonates. All patients were rehabilitated with a maxillary overdenture supported by a CAD/CAM polyether-ether-ketone (PEEK) implant-supported bar. The outcomes of the study were the passive fit/adaptation of the bar, the 1-year implant survival, and the success rates of the implant-supported overdentures. Results. 15 patients (6 males, 9 females; mean age 68.8±4.7 years) received 60 implants and were rehabilitated with a maxillary overdenture supported by a PEEK bar, designed and milled from an intraoral digital impression. The intraoral scans were integrated with face scans, in order to design each bar with all available patient data (soft tissues, prosthesis, implants, and face) in the correct spatial position. When testing the 3D-printed resin bar, 12 bars out of 15 (80%) had a perfect passive adaptation and fit; in contrast, 3 out of 15 (20%) did not have a sufficient passive fit or adaptation. No implants were lost, for a 1-year survival of 100% (60/60 surviving implants). However, some complications (two fixtures with peri-implantitis in the same patient and two repaired overdentures in two different patients) occurred. This determined a 1-year success rate of 80% for the implant-supported overdenture. Conclusions. In this study, the combination of intraoral and face scans allowed to successfully restore fully edentulous patients with maxillary overdentures supported by 4 implants and a CAD/CAM PEEK bar. Further studies are needed to confirm these outcomes.
