Abstract

Objectives The purpose of this within-patient study was to compare two implant-assisted overdentures (IAOs) reinforced either with polyether-ether ketone (PEEK) or cobaltchromium (CO-CR) regarding the percentage of occlusal contact using a digital occlusion analysis system (Occlusense) and to assess patient satisfaction and Oral Health–Related Quality of Life (OHRQoL). Subjects and methods Ten complete edentulous subjects were eligible. All patients were delivered two mandibular implant-assisted overdentures with two reinforcement materials, CO-CR (group I) and PEEK (group II).The mandibular overdentures were retained to the underlying implant fixtures by ball and socket attachments. Patients were evaluated three months after each overdenture use. For groups, the percentage of occlusal contact, the VAS, and the OHIP-14 questions were evaluated. Results There was a significant difference in the evenness of occlusal force distribution between different areas in both groups, with a higher percentage of occlusal force distribution in group II than group I in the premolar area. Regarding satisfaction of the patient and OHRQoL, no significant difference between the two groups was revealed. Conclusion Mandibular implant overdentures reinforced with PEEK offer promising results compared to mandibular overdentures reinforced with CO-CR regarding occlusal force distribution in the premolar region. Whilst, patient satisfaction and Oral Health–Related Quality of Life (OHRQoL) seem equal for both groups.
