Mini Dental Implant-Retained Removable Partial Dentures: Treatment Effect Size and 6-Months Follow-up
Objective: The aim was to compare esthetic outcomes, masticatory performance and a comfort of removable partial denture (RPD) wearing after receiving: clasp-retained RPD (C-RPD) or mini dental implant- retained RPD (MDI-RPD) in the mandible. Materials and Methods: A sample of 88 patients (Kennedy...

| Summary: | Objective: The aim was to compare esthetic outcomes, masticatory performance and a comfort of removable
partial denture (RPD) wearing after receiving: clasp-retained RPD (C-RPD) or mini dental implant-
retained RPD (MDI-RPD) in the mandible. Materials and Methods: A sample of 88 patients (Kennedy
Class I) with all posterior teeth missing and a linear support for a RPD participated. A total of 52
patients (36 females, 16 males; 56 to 84 years old) participated in the C-RPD group and 36 patients
(26 females, 10 males; 43 to 81 years old) in the MDI-RPD group. All MDIs were placed adjacent to
the last remaining mandibular anterior tooth or one tooth length posteriorly. The new RPDs had Co-
Cr frameworks with lingual plate major connectors; the MDI-RPDs were retained by O-ball matrices
and the C-RPDs with clasps. Patients answered questions at pre-treatment and post-treatment stages
and after 6-months follow-up: how satisfied they had been with esthetic appearance, how confident
they were while chewing hard food, how satisfied they were with food comminution and they
also evaluated a comfort of RPD wearing. The 0-10 visual-analogue scale was used. Statistics included
descriptive methods, t-tests and the standardized effect-size calculation. Results: The MDI-RPD
wearers were more satisfied with their post-treatment esthetics, food comminution, a comfort with
RPDs and had better confidence while chewing than the C-RPD wearers. The MDI-RPD wearers reported
larger positive effect of the treatment. The results were consistent throughout the first 6-months
period. Conclusion: The MDI-RPD patients showed superior outcomes than the C-RPD patients after
the treatment and over the 6-month period. |
