Mini Dental Implants (MDI) For The Retention of Mandibular Overdentures - A Two-Year Report
Objectives: To evaluate the success rate of using 2 MDI's to retain mandibular overdentures over a 2-year period
Methods: 2 MDI (2.1mmx10mm) were placed in the mandible of 31 fully edentulous participants at the canine regions using a flapless surgical procedure. Soft liner was added to the denture at the sites of the implants to obtain temporary retention. 2 months after surgery, the soft liner was replaced by O-ring attachments to achieve retention from the implants.Implant success rates, plaque index (PI), probing depths (PD), bone loss around implants (from radiographs), mechanical and prosthetic complications of the dentures and patients' satisfaction levels using visual analog scores (VAS) during function and social interaction were evaluated at 3, 12 and 24 months.
Results: Of the initial 31 participants, only 25 completed this 24-month trial. The 2-year success rate was 93.8 %. PI, GI and vertical marginal bone loss increased significantly (p<0.05) across the 3 observation periods. PD and horizontal bone loss were significant only ant 3 and 12 months. The median VAS for function increased from 2.00 (control) to 10.00 (3-month), 9.50 (12-month) and 10.00 (24-month at p<0.05. Median VAS for comfort increased from 2.5 (control) to 9.00 (3-month), 9.500 (12-month) and 10.00 (24-month) at p<0.05.Incidence of mechanical and prosthetic complications were also noted.
Conclusions: Within the limitations of this study, the results indicated that placement of 2 MDI's as retentive elements for mandibular complete dentures can improve the participants-centred outcomes of satisfaction with their dentures with regards to function and comfort, thereby improve the quality of life of patients
