Digital PEEK framework and patient satisfaction compared to conventional metal framework in removable partial dentures. A clinical trial

Abstract

Introduction: Utilization of removable partial dentures (RPD) is inevitable in some patients that are not indicated for any other treatment option, thus patient satisfaction with this line of treatment is of great importance. However, a notable need exists to advance materials and fabrication technologies due to the undesirable health outcomes linked with current RPDs. Aim: In this study patient satisfaction with conventionally manufactured metal RPD framework, was compared with their satisfaction using digitally milled PEEK (Juvora) framework. Methods: Ten patients were selected having class I partially edentulous mandibles. A conventional metal framework RPD was constructed for each patient, then another RPD with milled PEEK framework was digitally fabricated for each one of them. Each patient had the chance to use each denture for three months, then questionnaires were filled to assess their satisfaction. Results: The questionnaires were statistically analyzed and resulted in more patients' satisfaction with the digital PEEK framework RPD, than with conventional metallic RPD framework. Conclusion: PEEK material increases patients' satisfaction with RPDs than the conventional metal framework material, thus decreasing patients' complaints from removable appliances.

PEEK Versus Metallic Framework For Extracoronal Attachment Mandibular Bilateral Distally Extended Removable Dental Prosthesis (RDP) Evaluation of Abutments Bone Height Changes and Patient Satisfaction. A Randomized Clinical Trial.

“…The aim of this study was to evaluate the effect of PEEK and Co-Cr as framework material for extra coronal attachment retained RDP on bone height changes to distal abutments and patient satisfaction, as (Mohamed, and Rasha, 2019) 32 concluded that Digitally fabricated RDP frameworks made of PEEK material allows RDPs patients to be more satisfied with their prosthesis than conventional metallic frameworks, thus extending the application of RDP and decreasing patients' rejection to the removable appliances, which will serve to restore more partially edentulous cases with great satisfaction and least complaints.…”

Assessment of Acoustic Speech Signals and Patient Satisfaction With Two Partial Denture Framework Materials in Maxillary Kennedy Class Iv Cases. A Randomized Crossover Study.

“…The thickness of the denture base has a direct effect on the size of the oral cavity specially in the vertical direction as it becomes shorter so the presence of more vertical space in the Co-Cr group making more freedom and comfort for the tongue articulating position nearest to the pre-prosthesis position with the palatal tissue. (23) Regarding patient satisfaction with each prosthesis; patient comfort was higher in the PEEK group than Co-Cr group and this could be attributed to the weight of the prosthesis which usually has a major influence on the patient's comfort. (24,25) PEEK has a low specific weight thus allowing the construction of light weighed prostheses with good functionality offering high patient satisfaction and comfort through function.…”

“…This is in agreement with who stated that PEEK frameworks allowed the patients to be more satisfied with their removable prosthesis more than conventional Co-Cr RPD, which will help to rehabilitate more partially edentulous patients with high appreciation and minimum complaints. (28,29) Also, this suggests that the appearance of patients with missing anterior teeth plays a more influential role in their satisfaction with their prosthesis than their ability to speak (speech quality) with their prosthesis.…”

Clinical Applications of Polyetheretherketone in Removable Dental Prostheses: Accuracy, Characteristics, and Performance

“…Various clinical reports [ 18 , 71 , 78 ] have shown that PEEK (Bio-HPP) RPDs have a lower specific weight than CoCr RPDs, providing high patient satisfaction and comfort [ 18 ]. A randomized controlled trial [ 83 ] compared the satisfaction of 10 patients asked to wear metal and PEEK framework RPDs for 3 months. Patients were more satisfied with the milled PEEK framework RPDs than with the CoCr framework RPDs.…”
