Brief summary
This study was conducted to evaluate and compare the effect of acetal resin versus Polyether ether ketone (PEEK) partial dentures on abutment teeth supporting structures in Kennedy class I mandibular partial denture cases. Clinical assessments were conducted by assessing the pocket depth (PD), plaque index (PI), and gingival index (GI). Cone beam computed tomography (CBCT) was used to assess abutment alveolar bone height change.
Detailed description
This study was a parallel, two-group, double-blinded, randomized clinical trial. The proposal and consents were approved by the Research Ethics Committee. (REC) approval (P-PD-14-14). The Helsinki Declaration's guiding principles were followed when conducting the study. The Comprehensive Standards of Reporting Trials Statement (CONSORT) checklist's structure is followed in the study's presentation. The study was carried out at the Outpatient Clinic of the Removable Prosthodontic Department within the Faculty of Dental Medicine for Girls at Al-Azhar University. In this study, fifty patients were initially evaluated. After conducting clinical and radiographic assessments, twenty patients who satisfied the inclusion criteria were selected in accordance with the sample size calculation. Each patient received an explanation of every procedure, and informed consent was obtained. These twenty individuals were subsequently divided randomly into two distinct groups (ten in each): Group I: Ten patients received polyoxymethylene (acetal resin) partial dentures designed and fabricated using CAD/CAM technology. Group II: Ten patients received polyether ether ketone (PEEK) partial dentures designed and fabricated using CAD/CAM technology. All patients were evaluated clinically and radiographically. Clinical assessments were conducted by assessing the pocket depth (PD), plaque index (PI), and gingival index (GI) at denture insertion, three months later and six months later. Cone beam computed tomography (CBCT) was used to assess abutment alveolar bone height change at the time of denture placement, after three months, and after six months.
