EVALUATION OF PATIENT'S SATISFATION WEARING INNOVATIVE RHEIN83 EQUATOR IMPLANT OVD

Objectives: The purpose of this prospective clinical study was the evaluation of satisfaction of patients treated with an implant supported overdenture with the innovative Rhein83 Equator Profile Attachment. The evaluation regard: comfort, retention, stability, ability to chew(function), prosthetic complications, survival rates. Methods: The 10 participating patients (4 males, 6 females, mean age 68±10years) wearing mandibular implant overdentures retained by innovative Rhein83 Equator Profile Attachment participated in this clinical study. From 2 to 3 implants were placed in edentulous mandible. Prosthetic rehabilitation was realized 6 weeks after implantation. Patients' satisfaction was evaluated with a questionnaire regarding: comfort, ability to chew (function) with a VAS from 1 to 5. Survival rates and prosthetic maintenance procedures or complications were also recorded during the follow-up period. Results: Comfort: it passed from 1,28±0,44 before treatment to 4,37±0,51 after. Ability to chew: it passed from 2,1±0,83 before treatment to 3,78±0,74 after. During a mean observation time of 12±3 months no implant was lost and no periimplantitis occurred (100% survival rate). Maintenance: No loose abutment or fractured tooth occurred, while 1 relining was necessary. Substitution of the resilient component is made routinely every year. Conclusion: Within the limitations of this study, it can be concluded that implant retention may play a significant role on overall patient satisfaction with implant overdenture. This new type of attachment appears to be promising.
