Functional, Patient-Centered and Bone Remodeling Outcomes in Two Narrow-Diameter Implant Retained Mandibular Overdenture Wearers After 5 Years of Follow-Up: A Prospective Case Series
Objectives
This prospective longitudinal case series investigated changes in functional, radiographic, and patient-centered outcomes in users of two narrow-diameter implant-retained mandibular overdentures (IMO) over a 5-year follow-up.
Materials and Methods
Twenty-four patients from a previous 3-year study (8 man, 16 women, 71.58 ± 7.03 years, mean mandibular edentulism duration 23.9 ± 14.4 years) were invited for a 5-year follow-up evaluation of radiographic and functional parameters. Masticatory function (MF) was assessed using the Swallowing Threshold Test (ST), with X50 and B cut-off values indicating satisfactory performance. Oral health-related quality of life (OHRQoL) was evaluated using the OHIP-Edent questionnaire. The Posterior Mandibular Area Index (PAI) was analyzed using digital panoramic radiographs. Data was analyzed using multilevel mixed-effects linear regression.
Results
Twenty participants completed the 5-year follow-up evaluation. ST_X50 (4.00–3.70; p ≤ 0.01; 95% CI: 0.47–1.82) reached a significant reduction along with an increased number of masticatory cycles (59.33–65.60; p ≤ 0.01; 95% CI: 0.32–1.11) between years. The number of IMO wearers presenting satisfactory mastication increased but persisted as unsatisfactory in nine participants by year 5. Declines in the Functional Limitation and Physical Disability domains of OHRQoL were noted, with unsatisfactory mastication correlating with higher pain (coef: 2.5; p: 0.03; 95% CI: 0.25–4.74) and psychological disability scores (coef: 0.94; p ≤ 0.01; 95% CI: 0.19–1.68). PAI increased significantly (1.13–1.68; p ≤ 0.01; 95% CI: 0.24–0.56), indicating ongoing bone remodeling.
Conclusions
Although MF and bone parameters improved over 5 years, persistent unsatisfactory mastication continued to negatively affect quality of life. These findings underscore the interdependence between functional and patient-centered outcomes in IMO users.

期刊介绍：
Clinical Oral Implants Research conveys scientific progress in the field of implant dentistry and its related areas to clinicians, teachers and researchers concerned with the application of this information for the benefit of patients in need of oral implants. The journal addresses itself to clinicians, general practitioners, periodontists, oral and maxillofacial surgeons and prosthodontists, as well as to teachers, academicians and scholars involved in the education of professionals and in the scientific promotion of the field of implant dentistry.
