Mini-implants supported kennedy class I removable partial dentures - a 3-year follow-up outcomes.

Purpose/Aim: Clinical outcomes, marginal bone loss (MBL) and Patient Reported Outcome Measures (PROMs) in Kennedy Class I patients without posterior teeth, rehabilitated with mini-dental implants (MDIs) in canine/first premolar sites supporting removable partial denture (RPD) have not been documented. The purpose was to assess radiographic and clinical outcomes and PROMs of MDIs supporting Kennedy class I free-end saddle RPDs in a controlled prospective study. Materials and Methods: Ninety patients received MDI-retained RPDs. Patients were recalled on 12, 24 and 36 months. Marginal bone loss (MBL), Modified Plaque (MPI) and Bleeding (MBI) Indices were assessed. MDI and prosthodontic complications were recorded, as well as PROMs using OES, CFQ and OHIP14 questionnaires. Results: The 1-year success rate was 97.6% in 86 responding patients (4 MDIs were lost soon after loading, 2 in the mandible and 2 in the maxilla). Mean 1-year MBL was 0.24 ± 0.36mm, and 0.32 ± 0.49 mm after two years in 61 patients who responded. Mean MBL was 0.40± 0.51 in 56 respondents after 3 years. No MDIs were lost after the first year. The success rate was 96% and the survival with good prognosis 0.8% after 2 years ; it was 95.2% and 1.6% after 3 years, respectively. A bit higher MBL was recorded in females and younger patients, without significant differences in any observation stages (P>.05). All questionnaires showed high treatment effects which remained unchanged throughout the 3-year observation period. Conclusions: Two MDIs in previous canine/first premolar sites supporting free-end saddle RPDs is a successful treatment option according to our 3-year results.
