“…The current evidence recommends clinicians to use MOs retained by two implants, both with conventional and immediate loading (IML) protocols . When using CL, MOs retained by NDI show a high predictability, are cost‐effective, and capable of significantly improving users’ quality of life by promoting a high level of patient satisfaction in a short period . The IML protocol also presents adequate predictability but is more dependent on intrinsic factors that are mainly related to the bone site characteristics .…”

Background Biological responses to different loading protocols during the bone healing phase in subjects with long time since edentulism, rehabilitated with narrow diameter implants (NDIs) to retain mandibular overdentures (MOs), are still unavailable. Objective This randomized clinical trial compared the peri‐implant health, implant stability, and concentrations of pro‐ and anti‐inflammatory cytokines in the peri‐implant crevicular fluid (PICF) in mandibular edentulous patients under conventional (CL) and immediate loading (IML) during healing. Methodology Twenty totally edentulous patients received two NDIs (2.9 × 10 mm, Facility NeoPoros) placed in mandible anterior region and were randomly assigned to two loading protocols: CL (n = 10) and IML (n = 10). The following clinical outcomes were evaluated 1, 2, 4, 8, and 12 weeks after surgery: (a) peri‐implant tissue health (gingival index‐GI, plaque index‐PI, calculus‐presence CP, probing depth‐PD, and bleeding on probing‐BOP); (b) implant stability quotient (ISQ); and (c) IL‐1β, IL‐6, IL‐10, and TNF‐α levels in the PICF analyzed by ELISA. Results The CL group showed significantly higher CP scores at weeks 8 and 12. The IML group showed significantly higher GI from the first week onwards. The IML group presented significantly lower PD at all follow‐up times, and higher BOP rates than CL at week 12. The ISQ values of the CL group were higher than those of the IML group, except at week 4. The IML group released significantly more TNF‐α between weeks 1 and 4 and more IL‐1β during week 4‐12, while releasing less IL‐6 until week 8, mainly at week 2 (−47.6%). The release of IL‐10 was similar for both groups and increased progressively over time. At week 12, the IML group released 45.74% more IL‐10 than the CL group. The survival rates were 95% and 90% for CL and IML, respectively. Conclusion The IML group presented more favorable PD at all evaluation times; the differences between the other clinical parameters were less systematic. The implant stability and the inflammatory marker concentrations were more stable in the CL group.

“…Studies that evaluated patient satisfaction after treatment with NDI or MI implant‐retained MO reported a direct positive impact on the patients’ quality of life in terms of satisfaction, comfort and masticatory ability . These improvements can already be perceived 3 months after conversion to implant‐retained MO . The latter is mainly due to the increased comfort and high satisfaction with the prosthesis’ improved retention and stability.…”

“…[21][22][23][24][25] These improvements can already be perceived 3 months after conversion to implant-retained MO. 26 The latter is mainly due to the increased comfort and high satisfaction with the prosthesis' improved retention and stability. Moreover, the reported success and survival rates, peri-implant health and marginal bone loss outcomes associated with MI and NDI are similar as those of SDI.…”

This study reviews the clinical and radiographic outcomes of Mini-implants (MI) and Narrow Diameter Implants (NDI) as mandibular overdenture (MO) retainers. Six databases were consulted for clinical studies that evaluated implants with diameter ≤3.5 mm. Data on the MI and NDI for survival and success rate and peri-implant bone loss and were collected and submitted to meta-analysis. Thirty-six studies were included, 24 reporting MI performance and 12 describing NDI results. The MI group comprised data from 1 cross-sectional clinical study, 3 retrospective longitudinal (RL) clinical studies, 13 prospective longitudinal (PL) clinical studies and 7 randomised clinical trials (RCT) with follow-up periods ranging from 1 day to 7 years. Eight studies used conventional loading, thirteen used immediate loading, two studies used both loading types, and one study did not report. The NDI group comprised data from 3 RL clinical studies, 6 PL clinical studies and 3 RCT with follow-up ranging from 6 months to 10 years. Ten studies used conventional loading, 1 study used immediate loading, and 1 study did not report. The average survival rates of MI and NDI studies were 98% and 98%, respectively, while the average success rates were 93% and 96%, respectively. The average peri-implant bone loss after 12, 24 and 36 months was 0.89, 1.18 and 1.02 mm for MI and 0.18, 0.12 and -0.32 mm for NDI. Both MI and NDI showed adequate clinical behaviour as overdenture retainers. The NDI showed a better long-term predictability to retain OM with most studies adopting conventional loading.

“…Advanced alveolar bone resorption, however, frequently impairs the stability of the denture, particularly in the mandible, preventing the complete success of the treatment . Associating dental implants to this therapeutic approach can improve the treatment success rate significantly by increasing denture stability, a result that can only be achieved through a mechanism that reliably connects prosthesis and implants: the attachment system. Attachments are, therefore, at the heart of this treatment approach and may draw the line between success and failure.…”

Background Clinical success with mandibular implant overdentures is highly dependent on a reliable attachment system connecting prosthesis and implants. Purpose To compare the levels of retention and patient‐based outcomes on implant overdentures retained/supported by cylindrical (LA) and ball (RA) attachment systems overtime and investigate their relationship. Materials and Methods Attachment retention (Newtons), and patient satisfaction with the treatment, prosthesis stability, and ability to chew (VAS, 100 mm) were assessed in a crossover trial for both attachment systems at baseline, 1 week, 3, 6, and 12 months and compared to preintervention values. Patients' preference was also recorded. Results Mean retention of worn attachments and patient satisfaction with denture retention assessed in the preintervention phase were 3.2 N (SD 4.9) and 23.5 mm (IQR 6.5‐65.5), respectively. Overall mean retention along the study was higher for RA than LA (difference of 5.0 N, 95%CI: 2.5‐7.6; P = 0.0005), declining significantly overtime (P < 0.0001), more steeply for the cylindrical attachment. Differences in VAS ratings between attachments were nonsignificant in the crossover phase (P > 0.05), but general satisfaction, satisfaction with retention, and comfort were significantly higher when compared with preintervention scores (P < 0.05). Ratings of retention decreased significantly overtime for both systems and earlier for LA than RA. Satisfaction was lower when retention was either too low or too high, although there was large variation in this association. At the end of the study, all participants chose to remain with the attachment system that they had received last. Conclusions Attachment selection should be based on patients' individual characteristics and expectations as satisfaction with the attachment retention and denture stability vary largely among patients.
