“…This literally means that the clinical absence of erythema, bleeding on probing, inflammation, and suppuration, without considering specific ranges of probing depth or clinical or radiological bone loss, is currently synonymous with peri-implant health. 29 In our opinion, this is much of a periodontal vision of the matter, which detracts from much diagnostic and therapeutic potential to this problem. For some authors, such as Papaspyridakos and colleagues, assessing success should be related to at least four levels of integration related to implant level, peri-implant soft tissue, prosthesis, and patient's subjective evaluation.…”

Purpose The aim of this study was to establish an objective criterion in terms of marginal bone level (MBL) to know the prognosis of an implant. Materials and Methods A group of 176 patients in whom 590 implants were placed were included in this retrospective study. Patients older than 18 years, presenting either Kennedy class I or II edentulous section, or totally edentulous at least in one of the dental arches were included in this study. Those with any type of disturbance able to alter bone metabolism or with nontreated periodontal disease were excluded. Data on radiographic MBL at loading, 6 and 18 months later, age, gender, smoking habits, history of periodontitis, bone substratum, implant, and prosthetic features were recorded. Nonparametric receiver operating curves (ROC) were constructed for the MBL at 18 months in order to establish a distinction among high bone loser (HBL) and low bone loser (LBL) implants. Differences as a function of main variables were also determined, particularly abutment height and periodontal disease. Results HBL implants lost at least 0.48 mm of MBL 6 months after loading; they reached at least 2 mm of MBL 18 months after loading. MBL rate followed a nonlinear trend, except in implants restored over long prosthetic abutments and in patients with history of severe periodontitis; in whom the rate of MBL over the time was nearly zero. Conclusion Implants that lose more than 0.5 mm of marginal bone 6 months after loading are at great risk of not being radiographically successful anymore. Therefore, 0.5 mm of MBL is proposed as a distinctive and objective criterion of success in Implant Dentistry within a 6‐month follow‐up period. A prosthetic abutment height ≥2 mm resulted the most protective factor in the peri‐implant bone maintenance.

“…Recent data has revealed that it presents the most common etiological factor for late implant loss [ 2 ]. Considering the increase in the number of patients undergoing restorative treatment through dental implants and accordingly the increments in the prevalence of peri-implantitis (15–57% at the patient level and 8–28% at the implant level) [ 3 ], it is imperative to apply effective treatment methods to manage these conditions. Otherwise, if peri-implantitis lesions are left untreated, they progress in a non-linear and accelerating manner [ 1 , 4 ].…”

Objectives To compare the 3-year clinical and radiographic outcomes of two different reconstructive surgical management of peri-implantitis using a bone substitute in combination with either concentrated growth factor (CGF) or collagen membrane (CM). Material and methods Fifty-one patients who had at least one implant presenting peri-implantitis with an intrabony defect were filled with a xenogenic bone grafting material and covered either CGF or CM. Clinical and radiographic assessments were carried out at baseline and postoperative years 1 and 3. Three different composite outcomes were defined to evaluate treatment success at a 3-year follow-up. The effects of possible prognostic indicators on treatment success were identified by using multilevel regression analysis. Results The changes in probing depth (PD) and radiographic vertical defect depth (VDD) between baseline and year 1 and baseline and year 3 presented significantly greater decreases for the CM group in comparison with the CGF group (p < 0.05). No significant differences between the two treatment modalities were demonstrated regarding treatment success outcomes. History of periodontitis, VDD at baseline, and the number of intrabony defect walls revealed significant impacts on treatment success (p = 0.033; OR = 3.50, p = 0.039; OR = 0.975, and p = 0.024; OR = 7.0 and p = 0.019;OR = 6.0, respectively). Conclusions CM in combination with a bone substitute seems to have slightly better outcomes compared to the CGF membranes in reconstructive surgical therapy of peri-implantitis. The history of periodontitis, baseline VDD, and peri-implant bone defect configuration could be possible predictors influencing treatment success. Trial registration ClinicalTrials.gov NCT04769609. Clinical relevance For the reconstruction of peri-implant bone defects, using a bone substitute in combination with a collagen membrane may show more favorable outcomes.

“…Early implant failure is defined as failure prior to the connection of prosthetic restoration [ 1 ] and considered to be low [ 2 ]. Early implant failure is usually attributed to biological factors, surgical trauma, and impaired healing that resulted in a failure to achieve osseointegration [ 3 ].…”

The effect of type of specialty (periodontology/oral surgery) on early implant failure: a retrospective “Big-Data” study from a nation-wide dental chain in Israel

Objectives To evaluate early implant failure rate of implants placed by maxillofacial-oral surgeons and periodontists. Material and methods A nested case-case study was performed to analyze treatment outcome of 27 oral surgeons and 30 periodontists who performed at least 100 dental implants between 2017 and 2019 in 54 clinics of “Maccabi-Dent,” a nation-wide dental chain. A total of 26,865 implants were evaluated. Results The early failure rate of 1.3% achieved by the periodontists was lower than the 1.7% early failure rate achieved by oral surgeons. Differences were not statistically different. Oral surgeons in the study cohort were insignificantly older in age, with more years of experience as dentists and as specialists. However, the only parameter found to be a predictor to early implant failure in a linear regression model was related to postgraduate training. Explicitly, the mean number of implants placed during specialty program. This number was higher for the periodontists and found to be significantly contributing predictor to early implant failure. Clinicians’ age and years of experience as dentists or as specialist were not found to be predictors to early implant failure rate. Conclusions No statistically significant differences were found in early implant failure rate between oral surgeons and periodontists. The number of implants placed during specialty program has a statistical predictive value to early implant failure rate. Clinical relevance Care and attention should be taken to re-evaluate clinical training in the field of implantology during specialty program. To optimize surgeons’ control on treatment outcome.
