“…Comparing the mean difference of probing depth between both groups after all follow up periods revealed insignificant difference (P>0.05). This was in accordance with several studies which revealed insignificant differences between both groups in probing depth aspects (50)(51)(52)(53)(54)(55).…”

Purpose: To evaluate the influence of 2 different loading protocols on single implant supported overdentures, immediate and conventional protocols on the supporting structures regarding: The extent of resorption of peri-implant bone and clinical evaluation of peri-implant soft tissue. Material and Methods: ten completely edentulous patients was selected to receive single implant supported overdenture. They have been divided after the insertion of implant into two groups according to time of loading. Group I received ball and socket attachment and loaded after 3 months of surgical procedures, while Group II was loaded within 7 days from surgery. Then all patients were evaluated clinically regarding probing depth, bleeding and plaque index and radiographically at the day of loading, 3, 6 and 9 months postoperatively. Results: comparison between the two groups in marginal bone loss was insignificant except in the first two periods, while probing depth was insignificant except at (6 to 9 month). For bleeding and plaque index, it was insignificant except at time of insertion for bleeding index. Conclusions: Immediate loading of single implants supporting a ball-retained mandibular overdenture is associated with more marginal bone resorption when compared with delayed loading of implants after 9 months follow up but it still can be used with single implant supported overdenture. Clinically, immediate loading had probing depth and bleeding index higher than delayed loading, while for plaque index for both loading protocols was almost the same.

“…IODs in anterior mandible seems to reduce the treatment time and had comparable clinical results with the delay loading protocol. [16][17][18][19][20] There are different attachment systems for mandibular implant-retained overdentures to minimize movement of the denture without producing stress on the implants. 21,22 Researchers have done studies comparing different attachment systems used to retain two IODs with delayed loading protocols.…”

Purpose: There is no enough evidence present on the success of single implantretained mandibular overdentures (SIMO) with Dalla Bona and Locator attachments. This study aims to compare crestal bone loss and patient satisfaction with SIMO with Dalla Bona and Locator attachment following immediate loading protocols. Material and Methods: Twelve patients included in Group 1 received immediate SIMO with Dalla Bona attachments, and another twelve patients in Group 2 received immediate SIMO with Locator attachments in the mid symphyseal region. The follow-up was scheduled at 6 and 12 months after implant placement. The patient satisfaction with the denture was evaluated with the visual analog scale (VAS) score. The data obtained were statistically analyzed with the independent student t-test for intergroup comparison and repeated measures of ANOVA followed by Bonferroni's Post hoc analysis for intragroup comparison of mean crestal bone loss at a different time interval. Results: Ten patients each in both the groups were available for follow-up. Crestal bone loss at 6 months follow-up for Dalla Bona group was 0.42 ± 0.10 mm on the mesial side and 0.43 ± 0.14 mm on the distal side and at 1 year 1.54 ± 0.16 mm on the mesial side and 1.66 ± 0.13 mm on the distal side. The mean crestal bone loss at 6 months follow-up for Locator group was 0.48 ± 0.16 mm on the mesial side and 0.45 ± 0.11 mm on the distal side and at 1 year was 1.71 ± 0.22 mm on mesial side and 1.74 ± 0.28 mm on the distal side. There was difference in bone loss at 6 months (mesial: 0.06 mm, p = 0.327; distal:0.02 mm; p = 0.726) and at 1 year (mesial: 0.17 mm, p = 0.063; distal: 0.08 mm; p = 0.423) in between two groups but the difference was statistically insignificant. There was a significant difference found in the VAS score for patient satisfaction with SIMO with Dalla Bona attachments and Locator attachments at 6 months (54.2 vs. 51.8, p = 0.005) and 1 year (60.6 vs. 55.2, p = 0.005). Conclusions: Patient satisfaction with SIMO with Dalla Bona attachments was higher during the follow-up. SIMO with Dalla Bona attachments had less crestal bone loss and less prosthetic complications when compared to Locator attachments, although the difference in the bone loss was statistically insignificant.

ObjectivesLongitudinal 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 and methodsThis 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.Results164 (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).ConclusionMaxillary MDI overdenture treatment yields significant OHRQoL improvement when at least 5 MDIs survive, preserving functional comfort.
