ABSTRACT
OBJECTIVES:
Longitudinal evaluation of Oral Health-Related Quality of Life (OHRQoL) during treatment of flaplessly placed, one-piece mini-dental-implants (MDIs) for maxillary overdentures is rarely investigated, nor is the impact of MDI failures. MATERIAL ANDMETHODS:
This multicenter prospective cohort study evaluated the 3-year outcome of 5-6 MDIs in the edentulous maxilla in patients above 50 years with dentate mandible. Provisional dentures were provided before final prosthetic connection was established at 6 months. Postoperative discomfort was assessed using a visual analogue score (VAS). OHRQoL was investigated using the Oral Health Impact Profile (OHIP)-14 at baseline (preoperatively), postoperatively, post-prosthetic connection and after 3 years in function.RESULTS:
164 (78.4%) of the 204 placed MDIs were still in situ after 3 years, in 29/31 patients. Two patients lost 5/6 MDIs resulting in two prosthetic failures (6.45%). With regard to pain, a score of 4.1/10 (SD 2.8) was recorded on day 1, and 1.1/10 (SD 1.7) on day 7. A decrease in total OHIP-14 scores was observed postoperatively (15.6; SD 12.8) as compared to baseline (21.3; SD 13.1), with improvement of OHRQoL. Furthermore, this was statistically significant at connection of the final prosthesis (7.3; SD 6.7) (p = .006). The OHIP-14 improved less (p = .011) when experiencing one or more implant losses (9.5; SD 9.85), in comparison with no implant loss (20.7; SD 13.97). A failure of one MDI did not affect OHIP-14 score (p = .658); however, multiple failures did (p = .007).CONCLUSION:
Maxillary MDI overdenture treatment yields significant OHRQoL improvement when at least 5 MDIs survive, preserving functional comfort.Palavras-chave
