Item Effect of Implant Position on Clinical and Radiographic Outcomes of Locator-Retained Mandibular Overdentures: A 1-Year Prospective Study(Blackwell Publishing Inc., 2019) ELsyad M.A.; Maryod W.H.; Mostafa A.Z.; Department of Removable Prosthodontics; Faculty of Dentistry; University of Mansoura; Eldakahlia; Egypt; Department of Removable Prosthodontics; Faculty of Dentistry; University of Modern Science and Arts; Cairo; Egypt; Department of Removable Prosthodontics; Faculty of Dentistry; University of Hail; Hail; Saudi ArabiaPurpose: To evaluate the influence of implant position on clinical and radiographic outcomes of Locator-retained mandibular overdentures. Materials and Methods: Fifteen edentulous participants with compromised bone at canine regions of the mandible were given 2 implants in the premolar areas (study group, PM). The control group (CA) consisted of 15 participants who received 2 implants in the canine regions, matched to PM and assigned as historical control. For study and control groups, mandibular dentures were constructed and attached to the fixtures with Locator attachments using the delayed loading protocol. Clinical (plaque scores, gingival scores, pocket depth, and implant stability) and radiographic (marginal bone loss) outcomes were assessed after denture delivery (T0), 6 months (T6), and 12 months (T12) later. Results: The survival rate was 100% in both groups. All clinical and radiographic parameters increased significantly with time. No significant difference in plaque scores, gingival scores, or implant stability between groups was observed. PM group recorded significantly higher pocket depth and marginal bone loss than CA group at T6 and T12. Conclusions: Within the limits of this short-term clinical study, canine position for implants retaining mandibular overdentures with Locator attachments is preferred over the first premolar position, as it was associated with reduced peri-implant pocket depth and marginal bone loss after 1 year. � 2018 by the American College of ProsthodontistsItem Immediate versus early loading of mini-implants supporting mandibular overdentures: A preliminary 3-year clinical outcome report(Quintessence Publishing Co. Inc., 2014) Maryod W.H.; Ali S.M.; Shawky A.F.; Modern Science and Arts University; Cairo; Egypt; Faculty of Dentistry; 6 October University; Cairo; EgyptPurpose: The aim of this preliminary clinical report was to evaluate and compare the clinical outcomes of immediate and early loaded mini-implants (MIs) supporting mandibular overdentures. Materials and Methods: Thirty-six completely edentulous patients (20 men and 16 women) complaining of insufficient retention of their mandibular dentures were randomly assigned to two groups. Each patient received four MIs in the interforaminal area of the mandible using the nonsubmerged flapless surgical approach. In group 1 (G1), MIs were loaded with mandibular overdentures using the immediate loading protocol, while in group 2 (G2), MIs were loaded with overdentures using the early loading protocol. The cumulative survival rate was calculated using Kaplan-Meier analysis. Peri-implant health indices (Plaque Index/Bleeding Index), probing depths, and marginal bone levels were recorded for both groups after MI insertions and 6, 12, 24, and 36 months thereafter. Results: The cumulative implant survival rates were 91.7% and 96.7% for G1 and G2, respectively. G1 recorded significantly higher Plaque Index, Bleeding Index, and probing depths than G2 after 12 months, while other observation times demonstrated no significant difference between groups. Most of the recorded marginal bone loss occurred in the first year, and no significant bone loss was noted in subsequent years. After 6 months, marginal bone loss was significantly higher in G1 compared to G2, but no significant differences between groups were noted thereafter. Conclusions: Within the limitations of this study's research design and duration of follow-up outcome analyses, immediate and early loading protocols showed good clinical results with favorable peri-implant tissue response 3 years after implant insertion. Early loading of MIs supporting a mandibular overdenture appears to be preferable to immediate loading. � 2014 by Quintessence Publishing Co Inc.
