“…Progression of the experimentally induced peri‐implantitis continued, however, during the 12‐month “chronic phase” period and was more pronounced around implants with an HA‐coated surface than other implants. Spontaneous progression of experimental peri‐implantitis around different types of implants was also analyzed in studies by Monje et al () and Roehling et al (). In the study by Roehling et al (), the amount of bone loss was smaller around zirconia implants than that of titanium implants and it was suggested that the implant material influenced the progression of experimental peri‐implantitis.…”

“…Zitzmann et al () coined the term “spontaneous progression,” as disease progressed in the absence of ligatures. Several experimental studies have been performed using the spontaneous progression model of experimental peri‐implantitis to mimic natural disease progression around implants with varying geometry and surface characteristics (Albouy, Abrahamsson, & Berglundh, ; Albouy, Abrahamsson, Persson, & Berglundh, , ; Berglundh, Gotfredsen, Zitzmann, Lang, & Lindhe, ; Carcuac et al, ; Madi, Zakaria, Noritake, Fuji, & Kasugai, ; Monje et al, ; Roehling et al, ).…”

Objective To examine the progression of experimental peri‐implantitis around different implants placed in augmented and pristine sites. Materials and Methods Six labrador dogs were used. Three months after tooth extraction, four implants with different surface modifications were installed on each side of the mandible. A standard osteotomy was applied on one side, while on the contralateral side the osteotomy was modified, resulting in a gap between the implant and the bone wall. The gap was filled with a bone substitute and covered by a resorbable membrane. Three months after implant installation, implants were exposed and healing abutments were connected. Two months later, oral hygiene procedures were abandoned and a cotton ligature was placed in a submarginal position around the neck of all implants and kept in place for 4 weeks. Following ligature removal, plaque formation continued for 6 months (spontaneous progression period). Radiographs were obtained throughout the experiment, and biopsies were collected and prepared for histological evaluation at the end of the spontaneous progression period. Results Differences in bone loss during the spontaneous progression period between pristine and augmented sites were small. The size and vertical dimension of the peri‐implantitis lesion were larger at augmented than at pristine sites. Implants with non‐modified surfaces exhibited smaller amounts of bone loss and smaller dimensions of peri‐implantitis lesions than implants with modified surfaces. Conclusion Small differences in spontaneous progression of peri‐implantitis were detected between pristine and augmented sites. Implants with modified surfaces exhibited more bone loss and larger lesions than implants with non‐modified surfaces, irrespective of the type of surrounding bone.

“…Hence, careful interpretation of BOP values is necessary, since it might lead to a high false-positive rate when identifying the presence of peri-implant disease. Assessment of bleeding tendency using the modified sulcus bleeding index, or mucosal inflammation using the implant mucosal index, is likely more accurate in the detection of true peri-implant breakdown (French, Cochran, & Ofec, 2016;Mombelli et al, 1987;Monje, Insua, et al, 2018b).…”

Aim To assess the impact of keratinized mucosa (KM) width around dental implants on surgical therapeutic outcomes when treating peri‐implantitis. Material and Methods Surgically treated peri‐implantitis implants were divided into two groups (KM width < 2 mm and ≥2 mm). Retrospective data were obtained after implant placement (T0) and the day of peri‐implantitis surgical treatment (T1). Patients were later recruited (≥1 year after T1) for clinical and radiographic examination (T2). Outcomes were analysed using generalized estimating equation (GEE) models. Results A total of 40 patients (68 implants) (average follow‐up: 52.4 ± 30.5 months) were included in this study. From T0 to T1, no differences were found between KM groups in terms of peri‐implant probing depths (PPD) and bleeding on probing (BOP). However, sites with <2 mm KM exhibited significantly higher suppuration (SUP) and lower marginal bone level (MBL) (p > .01). Between T1 and T2, no major differences were noted on PPD reduction, BOP and MBL changes between the two groups. GEE modelling demonstrated that MBL severity prior to surgical therapy was a better predictor for implant survival than KM width. Conclusion Surgical outcome in treating peri‐implantitis was influenced by the severity of bone loss present at the time of treatment and not by the presence of KM at the time of treatment.

“…8 Likewise, Serino et al demonstrated that 34% of the defects did not exhibit circumferential bone loss, but rather, bone breakdown in the buccal areas. 11 In fact, it has been speculated that bone architecture and the proximity of dental implants to the cortical bone might play important roles on the frequency and severity of pathogenic bone loss on the buccal sites rather than the existence of linear resorptive patterns. 10 This is consistent with a recent canine study that demonstrated that peri-implantitis evolve in a more severe and aggressive fashion in the buccal sites compared to the lingual counterparts.…”

Background: Peri-implant defect morphology has shown to potentially impact upon the reconstructive outcomes for the management of peri-implantitis. Given the role that defect morphology plays upon the decision-making in the treatment of peri-implantitis, the present study aimed at assessing the morphology and severity of peri-implantitis bone defects and to insight on the patient-, implant-and site-related variables associated to these. Material and Methods:A cone-beam computed tomography study was carried out to classify peri-implantitis defects according to the type of defect, number of remaining bony walls and severity according to the extension of vertical bone loss.Three major defect categories were proposed: class I-infraosseous; class II-horizontal;class III-combined of class I and II. These were then subclassified into: (a) dehiscence; (b) 2/3-wall; and (c) circumferential-type defect. According to the severity the defects were further subclassified into: A: advanced; M: moderate; and S: slight. In addition, 20 site-, implant-, and patient-related variables were analyzed by generalized estimating equations (GEEs) of multilevel logistic regression models.Results: Based on an a priori power calculation, 332 implants were screened in 47 peri-implantitis patients. Of these, 158 peri-implantitis implants were eligible. The most prevalent defect morphology type was class Ib (55%) followed by class Ia (16.5%), and class IIIb (13.9%). On the contrary, the less frequent defect was class II (1.9%). The most frequent degree of severity was M (50.6%) with S (10.1%) being the least prevalent. Buccal bone loss was significantly greater compared to the other bony walls in class I and class III defects. Age was associated with the type of defect.Age and smoking habit were associated with the morphology of the defects, while smoking habit, type of prosthesis and distance to adjacent implant were associated with the severity of the defects (vertical bone loss).Conclusion: Peri-implantitis defects frequently course with an infraosseous component and often with buccal bone loss. Certain patient-, implant-, and site-specific variables are related with defect morphology and severity. However, morphological patterns for periimplantitis bone defects could not be proven (NCT NCT03777449).K E Y W O R D S alveolar bone, dental implants, diagnostic, implant stability, peri-implantitis, peri-implant mucositis
