Assessment of Polyetheretherketone Crown in Patients: An Original Research

Polyetheretherketone (PEEK) has a long history of usage in implant abutments, but it has not seen much applications in tooth-supported prosthetics. The purpose of this research was to examine the clinical performance of PEEK crowns as well as the level of patient satisfaction with them. The pilot study was designed as an in vivo longitudinal examination.

Twenty patients each received a PEEK crown during the procedure. In total, 22 implants were inserted, with 11 going into the maxilla and 9 into the mandible. One operator was responsible for carrying out each phase of the procedure. The resin cement was used to lute the crowns that were produced. Baseline, 3 months, 6 months, and 1 year after the crowns were placed, they were evaluated for various parameters using Modified Ryge's Criteria. These evaluations were performed at intervals of 3 months, 6 months, and 1 year. In addition, a questionnaire was used at the same time to assess the level of satisfaction felt by patients. Fisher's exact test was utilized in the process of analyzing the data that were gathered.

According to the findings, 92.5% of the crowns met the modified version of Ryge's criterion for a satisfactory rating. Three crowns had a fracture recorded. There was some chipping off observed in five of the crowns. There was not any significant difference in the other factors that were examined. The periodontal health of these three patients showed a slight degree of variance (P = 0.02).

The capacity of PEEK crowns to create high-quality prostheses that were deemed satisfactory with a reasonably low rate of fracture during the relative mean duration of 1 year was established by the application of Modified Ryge's Criteria. The PEEK crowns demonstrated their ability to produce quality prostheses.
