Background: Edentulous mandible rehabilitation via single implant mandibular overdenture (SIMO) became mundane as a facile therapy averred promising results. SIMO was reported to prone to fracture thus, represented a concern for the clinicians.
Objectives: This study targeted at assessing Satisfaction of the Patient and Oral Health–Related Quality of Life OHRQoL referring to (SIMO) reinforced by metal or PEEK frameworks in comparison to conventional complete denture CD.
Materials and Methods: Eighteen complete dentures were delivered for the eligible participants (group I). Three months later, they were evaluated for Satisfaction of patient and OHRQoL. Patient satisfaction was performed employing the visual analog scale (VAS). Assessment of OHRQoL by oral health impact profile (OHIP-14) was accomplished. Through pursuing the delayed loading protocol, in the midline region of the mandible, single implant was inserted. Each patient received two overdentures utilizing a crossover design; metal reinforced (Group II) and PEEK reinforced overdentures (Group III). Patient Satisfaction and OHRQoL for groups (II and III) were carried out following three months of using each overdenture. Questions of VAS and OHIP-14 were evaluated for both overdentures.
Results: SIMOs revealed statistically significant improvement compared to traditional dentures. Non-significant difference between SIMOs reinforced with metal or PEEK was demonstrated except for denture stability and retention in favor of PEEK reinforced SIMOs.
Conclusion: SIMOs ameliorated patient satisfaction together with OHRQoL when compared with CDs no matter the involved reinforcement material was. SIMOs reinforced with PEEK are deemed advantageous over the metal ones in terms of denture stability and retention.
