“…The implant position in posterior was identified as the risk indicator, with the RR value of 10.91 for risk of peri‐implantitis. Han and colleagues reported a survival rate of 95.8% in posterior region for 3‐year follow‐up . Douglas reported a high rate of implant failure of 6% with 2 years' function in posterior region with advanced alveolar ridge height resorption in treated periodontitis patients.…”

Background No nomogram of peri‐implantitis was reported before which is valuable for risk‐estimating, clinical decision‐making, and better‐patients‐communicating. Purpose To identify the risk indicators and develop a nomogram prediction model of peri‐implantitis in treated severe periodontitis patients. Materials and Methods A prospective study was conducted on 100 patients with 214 implants. Periodontal and peri‐implant parameters were evaluated at implant surgery procedure (T1), and at follow‐up (T2). Risk factors were analyzed by logistic regression analyses with generalized estimating equations. Nomogram was developed and the discriminatory ability of the model was analyzed. Results The incidence of peri‐implantitis at patient‐level and implant level were 16% and 11.2% respectively, with no implant lost. The variables associated with peri‐implantitis were the PDT1 ≥ 6 mm (%) > 10%, the implant position, length, and diameter after adjusting for covariates. A nomogram prediction model of peri‐implantitis were developed with factors of PD T1 ≥ 6 mm (%) > 10% and implant placed in posterior. The area under the ROC curves of stepwise model was 0.794. Conclusions The residual pockets and implants position were identified as predictors for the peri‐implantitis. The nomogram can be used to estimate the risk of peri‐implantitis in treated severe periodontitis patients.

Purpose To analyse randomised controlled clinical trials (RCTs) and prospective cohort studies reporting on the survival and failure rates of functionally loaded short implants (SI) based on the actual length of time in function. Materials and methods This meta‐analysis was conducted according to PRISMA guidelines for systematic reviews. Electronic and manual searches were conducted to identify RCTs and prospective cohort studies reporting survival and complication rates of short dental implants (≤6 mm) based on the time in function. Secondary outcomes included the location (maxilla or mandible), type of restoration (single crown [SC] versus fixed dental prosthesis [FDP]) and marginal bone loss (MBL). Results A total of 20 studies (11 RCTs and 9 prospective) fulfilled the inclusion criteria and featured a total of 1238 SI placed in 747 patients. The overall (early and late) mean percentage of short implant failure was 4%. SI with up to 1‐year follow‐up presented failure rate of 2%, while SI followed up for >3 years showed a failure rate of 10%. SI restored with SC presented a late failure rate of 4% while SI restored with FPD 2%. The late failure rate did not differ in terms of location (maxilla or mandible) both with 3%. Conclusion Short implants in function for more than 3 years presented higher failure rates compared to SI in function for <3 years. Splinting crowns supported by SIs in the posterior area should be considered. However, SI is a valid option for selected cases given their relatively high long‐term survival rates.

“…Bone loss less than 1.0 mm was shown in 12.7% implants, and bone gain as much as 1.9 mm was shown in 22.5% implants. No change in bone level was shown in 62.0% implants (Han, Tang, Zhang, & Meng, ). In the current study, the proportion of implants showing bone gain was 61.4%, which was even higher than that reported by Han et al…”

Objective: To evaluate the clinical outcomes of an early loading protocol of splinted implants with a fluoride-modified nanostructure surface and a tapered apex design for the therapy of posterior partial edentulism of mandible. Materials and Methods:One hundred and seven implants were placed in the mandible of 45 subjects at three centres in China. A minimum of two and a maximum of three implants were placed in an edentulous region using a one-stage protocol.Each subject received a screw-retained, splinted and fixed permanent prosthesis 6-8 weeks after surgery. Marginal bone level (MBL) change, implant survival and soft tissue health were assessed at 6, 12, 24 and 36 months after loading. A total of 92 implants from 40 subjects were recalled and investigated in this clinical trial. Results: After three-year loading, the survival rate of implant was 100%. On a subject level, there was a mean (±SD) marginal bone gain of 0.23 ± 0.48 mm at 36-month recall and the change in MBL was statistically significant (p = .00061) compared with time of loading. On an implant level, the change in MBL was statistically significant (p = .03914, p = .01494, p = .00000) at 12, 24 and 36 months of loading compared with time of loading. Conclusion:Three-year data indicate that early loading protocol of splinted implants with a fluoride-modified nanostructure surface and a tapered apex design is feasible and safe for the therapy of partial edentulism in posterior mandible, which may contribute to bone gain when the suitable occlusal load and oral hygiene maintenance are kept.
