“…Early implant failure was defined as loss of the implant due to a lack of osseointegration or periimplantitis during 12 months after surgery. Late implant failure was defined as implant loss at > 12 months but within 10 years following implant surgery 37 . Prosthesis survival rate was defined as a prosthesis with a stable location and in good function 38 …”

BackgroundThe survival rate, marginal bone loss and soft tissue health of the Ankylos implants and the balanced base abutments in all‐on‐four or six implant restoration of edentulous or terminal dentition patients has not been reported in the clinical research.PurposeThis retrospective study aimed to evaluate the Ankylos implants and the balanced base abutments in all‐on‐four or six implant restoration of edentulous or terminal dentition patients after 1–8 years of follow‐up.Materials and MethodsA retrospective study was conducted based on the medical records of 33 patients who received all‐on‐four or six treatments from April 2014 to May 2020. Four radiographic examinations [immediate postoperative (T0), definitive restorations (T1), 1–3 years after prosthetic restorations (T2), and more than 3 years after prosthetic restorations (T3)] were obtained to evaluate vertical bone height (VBH). We also calculated the survival rate and examined the condition of soft tissue with this implant system in edentulous or terminal dentition patients. Three‐level linear model analyses were used to explore potential risk factors for VBH changes on the mesial and distal sides. The generalized linear model was used to analyze the influencing factors of BOP and plaque.ResultsA total of 218 implants were included in this study. The cumulative survival rate of the implants was 97.25% before the definitive prosthesis, 96.33% within 3 years of follow‐up and 95.32% after more than 3 years of follow‐up. The mean ± standard deviation (SD) bone losses of the VBH were 0.27 ± 0.05 mm (T1‐T3) on the mesial side and 0.49 ± 0.06 mm (T1‐T3) on the distal side. During 1–8 years of follow‐up, the height and angle of the abutment (p < 0.001), the mandible implant site (p < 0.001), the length of the implant (p = 0.014 < 0.05) and age (p = 0.029 < 0.05) showed statistically significant effects on vertical mesial bone height (VMBH) and vertical distal bone height (VDBH). The risk of BOP among participants who brushed three times a day was lower than those who brushed less than three times. The plaque risk of short abutment height was higher than the long abutment.ConclusionThe current study showed that the Ankylos implants with the balanced base abutments in all‐on‐four or six implants treatment is a viable and predictable option with a high survival rate and low marginal bone loss in edentulous or terminal dentition patients. VBH around the implants was strongly associated with the mandible implant site, abutment height and angle, the length of the implant and age. Moreover, teeth‐brushing times and abutment height significantly affect soft tissue health.

“…18 Within the literature, previous studies have identified some longterm risk factors of DIF, explicitly smoking, periodontal disease, medication-related DIF, and type 2 diabetes. [19][20][21][22][23][24][25] It has been reported that the adjusted odds ratio for implant failure for current smokers compared with non-smokers was 2.07 (95% confidence interval [CI] 1.19-3.62), 26 indicating a relative 2-fold increased odds for implant failures. 20 Although heterogeneity exists within the reports, weighted mean implant-level peri-implantitis prevalence was reported to be as high as 9.25%-22.7%.…”

IntroductionApproximately, 5.5 million dental implants are estimated to be surgically placed in the United States yearly, with an anticipated long‐term failure rate ranging from 3% to 10%. At the Salt Lake City Dental Clinic within the Department of Veterans Affairs (VHA), specific protocols have been established to mandate that clinicians present every dental implant case for review by a committee. To understand the effectiveness of this approach, a comparative data analysis was undertaken to compare local dental implant failure data against national VHA data.MethodsLeveraging electronic health records of veterans spanning from 2000 to 2021, we gathered procedural records related to dental implant placement or failure, demographic information, and medical history for individuals who received dental care at various dental clinics within the nationwide VHA network. Subsequently, statistical analyses were conducted using mixed‐effects Poisson regression models with cluster‐robust standard errors. Incident rate ratios (IRRs) for Utah‐specific and nationwide cohorts were ascertained.ResultsThe Utah VHA dental clinical data showed that there was a slightly lower prevalence of implant failure at 6.7% compared to the national cohort, which had a rate of 6.9%. The implant level failure rates were also low, with 4.20 (confidence interval [CI]: 3.68, 4.81) per 1000 implant placements per year for Utah cohorts. The adjusted IRR indicated a relative 16% reduction in risk among Utah Veterans (IRR 0.84, 95% CI [0.76–0.92]; p < 0.001).ConclusionsThe stringent protocols in place at Salt Lake City, which integrate evidence‐based practices and expert opinion for evaluating patient suitability for dental implant placement and subsequent care, contributed to the reduced risk among Utah Dental Clinic veterans pool compared to veterans of other states.
