“…Despite the high success rates, 1,2 dental implant failure may occur and is defined as the inadequacy of the tissues to establish or maintain the osseointegration. 3,4 Bacterial-associated peri-implant infection is considered an inflammatory process affecting the tissues around the implant in function, resulting in loss of supporting bone, and is reported to be one of most important reasons causing dental implant failure. 5 The oral cavity is a complex microecological environment, and 6 after implantation, the bacteria can invade the peri-implant soft tissue and may potentially progress deeper into the bone and undermine the osseointegration process.…”

To prevent peri-implant infection, a new antibacterial coating containing a halogenated furanone compound, ( Z -)-4-bromo-5-(bromomethylene)-2(5 H )-furanone-loaded poly( l -lactic acid) nanoparticles, has been fabricated. The current study was designed to evaluate the preventive effect of the antibacterial coating under a simulated environment of peri-implant infection in vivo. Microarc-oxidized titanium implants treated with minocycline hydrochloride ointment were used as positive control group, and microarc-oxidized titanium implants without any treatment were used as blank control group. Three kinds of implants were implanted in dogs’ mandibles, and the peri-implant infection was simulated by silk ligation and feeding high sugar diet. After 2-month implantation, the results showed that no significant differences were detected between the experimental and positive control groups ( P >0.05), but the data of clinical measurements of the blank control group were significantly higher than those of the other two groups ( P <0.05), and the bone–implant contact rate and ultimate interfacial strength were significantly lower than those of the other two groups ( P <0.05). Scanning electron microscope observation and histological examination showed that more new bone was formed on the surface of the experimental and positive control groups. It can be concluded that the antibacterial coating fabricated on implants has remarkable preventive effect on peri-implant infection at the early stage.

“…Reported success rates for oral implants are high; however, there is a lack of longitudinal data with at least 5 years of follow-up [2]. It has been suggested that several risk factors may impair long-term implant survival including jaw location (anterior vs. posterior region and maxilla vs. mandible) [3], implant dimensions (length, diameter, and implant design) [4], simultaneous or staged bone augmentation procedures [5], local bone density at the implant site [6], and patient-related risk factors such as age, smoking, history of periodontal disease, diabetes mellitus, and osteoporosis [7,8]. …”

PurposeRehabilitation of the incomplete dentition by means of osseointegrated dental implants represents a highly predictable and widespread therapy; however, little is known about potential risk factors that may impair long-term implant success.MethodsFrom 2004 to 2012, a total of 13,147 implants were placed in 4,316 patients at the Academy for Oral Implantology in Vienna. The survival rates after 8 years of follow-up were computed using the Kaplan-Meier method, and the impact of patient- and implant-related risk factors was assessed.ResultsOverall implant survival was 97% and was not associated with implant length (P=0.930), implant diameter (P=0.704), jaw location (P=0.545), implant position (P=0.450), local bone quality (P=0.398), previous bone augmentation surgery (P=0.617), or patient-related factors including osteoporosis (P=0.661), age (P=0.575), or diabetes mellitus (P=0.928). However, smoking increased the risk of implant failure by 3 folds (P<0.001) and a positive history of periodontal disease doubled the failure risk (P=0.001).ConclusionsSumming up the long-term results of well over 10,000 implants at the Academy for Oral Implantology in Vienna it can be concluded that there is only a limited number of patients that do not qualify for implant therapy and may thus not benefit from improved quality of life associated with fixed implant-retained prostheses.Graphical Abstract

“…The literature is divided as to whether advancing age is truly a risk factor for failure. 12,13 It has been suggested that with advancing age, there are changes in bone and collagen that may result in longer healing periods. An important note to make is that older patients may also have more alveolar bone atrophy, resulting in reduced bone volume and increasing the rate of failure.…”

Aim:The aim of this research is to determine which risk factors are associated with dental implant failure and survival. Materials and methods:Data pertaining to patients who received one or more dental implants from 2011 to 2013 in a regional center were retrospectively reviewed. This included a total of 302 Biomet 3i NanoTite Tapered Certain implants placed in 177 patients. All patients were followed up until the end of 2015.Results: This study found an overall success rate of 95%. Statistically significant factors that were found to affect implant survival were implant length, surgical technique, and presence of diabetes mellitus DM. Age, gender, body mass index (BMI), implant site, smoking, and variable operators were not found to have any significant implant on implant survival. Conclusion:This study has demonstrated that the incidence of implant failure and its complications is affected by a number of important factors that clinicians should consider when assessing patients. A follow-up study with a larger sample size, longer follow-up period, and details of the type of prosthetic rehabilitation would be beneficial in producing more definitive conclusions which may improve clinical practice.Clinical significance: Dental implants play an important role in modern-day dental rehabilitation. It is vital that clinicians understand the impact of variable risk factors on implant survival. This study will add to the growing literature on the subject.
