Material and Methods Electronic health record data from a university center were analyzed. Forty patient‐, implant/site‐, biologic‐, and prosthesis‐related variables were evaluated in relation to early failure, late failure, and peri‐implantitis. Bivariate and survival analyses were performed, followed by mixed‐effects regression models appropriate to each outcome. Robustness was assessed via clustered bootstrap resampling, penalized regression, and sensitivity analyses. Results A total of 264 patients and 554 implants were assessed. Cumulative implant failure was 6.8% (3.4% early; 3.4% late), and peri‐implantitis incidence was 7.6%. In multivariable analyses, self‐reported penicillin allergy (OR = 7.9; 95% CI: 2.7–23.7) and anterior implant location (OR = 5.4; 95% CI: 2.0–14.0) were associated with higher odds of early implant failure, whereas antihypertensive medication use (OR = 0.26; 95% CI:0.08–0.91) was associated with lower odds ( <jats:italic>p</jats:italic> &lt; 0.05). Late implant failure was associated with hypertension (HR = 2.1; 95% CI: 1.3–3.3), previously grafted sites (HR = 1.4; 95% CI:1.0–1.9), and bone‐level implants (HR = 10.4; 95% CI: 5.5–19.5). In cluster‐robust sensitivity analysis, the association between bone‐level implants and late implant failure was attenuated but remained significant (HR = 3.38; 95% CI: 1.96–5.84).

Materials and Methods Twenty‐four Ti and twenty‐four Zr abutments were divided by marginal grooves into 36 test and 12 control surfaces per material. Test abutments were mounted in a custom peri‐implant mucositis model and treated in triplicate with twelve modalities: glycine (GPAP) and erythritol (EPAP‐5 s and 20 s) air‐polishing; prophylaxis cup with paste; plastic, titanium and stainless‐steel (SS) curettes; and titanium, polyether‐ether‐ketone (PEEK) sonic, PEEK ultrasonic, SS sonic and SS ultrasonic tips. Post‐treatment analyses included stereomicroscopy, vertical scanning interferometry (VSI), scanning electron microscopy (SEM) and energy‐dispersive X‐ray spectroscopy (EDS). Results Air‐polishing was associated with a favourable combination of high cleaning efficacy and preserved native surface morphology. SEM and VSI analyses revealed scratching, gouging and material loss on titanium abutments following instrumentation with metallic devices, whereas EPAP preserved surface morphology. Zirconia abutments demonstrated minimal topographical disruption across most modalities; however, surface residues and material smearing were detected following nearly all treatments except EPAP.

This study evaluated real‐world implant survival in the anterior maxilla and examined whether risk patterns differ between early and late failure phases. Materials and Methods This retrospective study used electronic health record data from a nationwide dental network. A total of 14,079 implants placed in 8234 patients between 2014 and 2023 were analyzed. Implant failure was defined as removal or spontaneous exfoliation. Survival was assessed using Kaplan–Meier analysis and Cox proportional hazards models with patient‐level clustering. A 6‐month timing‐specific approach distinguished early from late failures, with restoration modeled as a time‐varying covariate. Results During a mean follow‐up of 6.0 ± 2.9 years, 358 implants failed, yielding a failure rate of 2.5% and an incidence rate of 0.43 failures per 100 implant‐years. Early failures accounted for 43.6% of failures.

Methods Clinical and radiographic data from 456 subjects with single implants were analyzed. Complication rates (caries, new restorations, tooth loss) of adjacent teeth were compared against three intra‐patient control groups (other quadrants) using data at restoration delivery as the baseline. Multivariate models assessed risk over short‐term (1–5 years) and long‐term (5–15 years) periods. Results Mean follow‐ups were 3.88 ± 1.75 years for the short‐term ( <jats:italic>n</jats:italic> = 456) and 8.90 ± 2.10 years for the long‐term ( <jats:italic>n</jats:italic> = 180) cohorts. Adjacent teeth showed significantly higher overall complication rates compared to all control groups in both the short‐term (8.0% vs. 2.2%–2.7%; ORs: 2.92–3.65) and long‐term follow‐ups (15.0% vs. 6.4%–7.8%; ORs: 2.16–2.57). A clear positional dichotomy emerged: mesial teeth showed pronounced short‐term caries susceptibility, while distal teeth drove a short‐term risk of tooth loss. Restoration needs remained consistently elevated. Bone‐level implants (short‐term OR: 0.44; long‐term OR: 0.38), narrow‐diameter implants (OR: 0.23), and pre‐existing orthodontic alignment (OR: 0.20) were associated with a lower incidence of complications, whereas patient‐level factors such as bruxism (OR: 5.78) and male gender (OR: 10.88) correlated with increased complication rates.
