“…On one hand these might be patient‐related issues such as smoking (Moheng & Feryn, ) or clenching (Manfredini, Bucci, Sabattini, & Lobbezoo, ) and prosthetic‐related issues on the other hand, such as the exact height of the restorations and correspondingly static and dynamic loading forces (Chang et al., )). The finding that the crown‐to‐implant ratio had no effect on the radio‐opacity of the neighbouring bone, however, is in accordance with several recent publications of finite element and clinical trials (Birdi, Schulte, Kovacs, & Chuang, ; Bulaqi, Mousavi Mashhadi, Safari, & Geramipanah, ; Mangano, Frezzato, Frezzato, & Mangano, ) that failed to show any impact of CIR on the peri‐implant bone.…”

“…Only 42 out of the 128 implants (32.8%) had a >2 CIR. Recently, Mangano et al [50], in a 5-year prospective study, followed 68 6.5 mm long implants in 51 patients. Twenty-nine out of the 65 implants (72%) were restored by means of single crowns.…”

Aim To determine cumulative success rate (CSR) of short and ultrashort implants in the posterior maxilla restored with single crowns. Patients and Methods We performed a retrospective study in 65 patients with 139 implants. 46 were ultrashort and 93 short. Implants were placed with a staged approach and restored with single crowns. Success rate, clinical and radiographic outcomes, and crown-to-implant ratio (CIR) were assessed after three years. Statistical analysis was performed by descriptive and inferential statistics. A log-binomial regression model where the main outcome was implant success was achieved. Coefficients and 95% confidence intervals were reported. Analyses were performed with Stata 13.2 for Windows. Results 61.54% of patients were female and mean overall age was 51.9 ± 11.08 years old. Overall CSR was 97.1% (95% CI: 92.4–98.9): 97.9 and 95.1% for short and ultrashort, respectively (P value: 0.33). Four implants failed. Covariates were not associated with CSR (P value > 0.05). Regression model showed coefficients correlated with implant success for ultrashort implants (0.87) and most of covariates but none were statistically significant (P values > 0.05). Conclusions Our results suggest that short and ultrashort implants may be successfully placed and restored with single crowns in the resorbed maxillary molar region.

Objectives:Risk factors in oral implantology are defined as local or systemic conditions that increase failure rates. The purpose of this paper is to evaluate the long-term survival rate of dental implants placed in patients presenting mechanical risk factors.Materials and Methods:This retrospective study was conducted only with patients presenting at least one of the following risk factors were included: Bruxism; crown-to-implant (C/I) ratio <0.8; abutment angulation. The overall implant survival was estimated using Kaplan–Meier analyses. Risk factors for implant failure were identified using the Cox proportional hazard regression models.Results:Eighty-nine eligible patients were enrolled in this study: They were both male (n = 56, 62.92%) and female (n = 33, 37.08%), with an average age of 53.24 (23–76 years), with 227 dental implants inserted. The mean follow-up was 13.6 years (range: 10–16 years). The overall 10-year Kaplan–Meier survival estimate with associated 95% confidence intervals was 86.34% (82.8, 87.1). Bruxism was the only variable that showed a statistically significant association with implant failure (P < 0.05) and a hazard ratio of 2.9, while both Crown to-implant and abutment angulations reported lower values of failure (P > 0.05).Conclusions:Within the limitations of this study, can be concluded that data suggested an evident relationship between bruxism and dental implant failure but further studies, with a larger sample and a different design are required to assess this relationship.
