Seven years after surgical treatment with DBBMC, patients, in an adequate SPT, maintained sufficient peri-implant conditions in many cases, particularly around SLA implants. Nevertheless, some patients required further treatment and some lost implants. The clinical decision on whether implants should be treated or removed should be based on several factors, including implant surface characteristics.

Objectives: To report the clinical outcomes for patients with implants treated for peri-implantitis who subsequently received supportive care (supportive peri-implant/ periodontal therapy) for at least 3 years. Material and methods:A systematic search of multiple electronic databases, grey literature and hand searching, without language restriction, to identify studies including ≥10 patients was constructed. Data and risk of bias were explored qualitatively. Estimated cumulative survival at the implant-and patient-level was pooled with random-effects meta-analysis and explored for publication bias (funnel plot) at different time intervals. Results:The search identified 5,761 studies. Of 83 records selected during screening, 65 were excluded through independent review (kappa = 0.94), with 18 retained for qualitative and 13 of those for quantitative assessments. On average, studies included 26 patients (median, IQR 21-32), with 36 implants (median, IQR 26-45). Study designs (case definitions of peri-implantitis, peri-implantitis treatment, supportive care) and population characteristics (patient, implant and prosthesis characteristics) varied markedly. Data extraction was affected by reduced reporting quality, but over 75% of studies had low risk of bias. Implant survival was 81.73%-100% at 3 years (seven studies), 74.09%-100% at 4 years (three studies), 76.03%-100% at 5 years (four studies) and 69.63%-98.72% at 7 years (two studies). Success and recurrence definitions were reported in five and two studies respectively, were heterogeneous, and those outcomes were unable to be explored quantitatively.Conclusion: Therapy of peri-implantitis followed by regular supportive care resulted in high patient-and implant-level survival in the medium to long term. Favourable results were reported, with clinical improvements and stable peri-implant bone levels in the majority of patients.

Within the limits of this study, the positive results suggest that the proposed technique may be a reliable option in selected cases.

Frailty is a highly prevalent condition in the elderly that has been increasingly considered as a crucial public health issue, due to the strict correlation with a higher risk of fragility fractures, hospitalization, and mortality. Among the age-related diseases, sarcopenia and dysphagia are two common pathological conditions in frail older people and could coexist leading to dehydration and malnutrition in these subjects. “Sarcopenic dysphagia” is a complex condition characterized by deglutition impairment due to the loss of mass and strength of swallowing muscles and might be also related to poor oral health status. Moreover, the aging process is strictly related to poor oral health status due to direct impairment of the immune system and wound healing and physical and cognitive impairment might indirectly influence older people’s ability to carry out adequate oral hygiene. Therefore, poor oral health might affect nutrient intake, leading to malnutrition and, consequently, to frailty. In this scenario, sarcopenia, dysphagia, and oral health are closely linked sharing common pathophysiological pathways, disabling sequelae, and frailty. Thus, the aim of the present comprehensive review is to describe the correlation among sarcopenic dysphagia, malnutrition, and oral frailty, characterizing their phenotypically overlapping features, to propose a comprehensive and effective management of elderly frail subjects.

Background: The present case series assesses the response to reconstructive therapy for the management of 2/3-wall peri-implantitis bone defects following submergedhealing guided bone regeneration. Material and Methods: Fifteen consecutive patients with 27 implants presenting periimplantitis were included. Guided bone regeneration was applied by means of autogenous bone/deproteinized bovine bone mineral grafting mixture and collagen membrane. Patients were assessed at baseline (T0) and at 6 (T1) and 12 months (T2). Clinical and radiographic variables defined the composite success criteria (probing pocket depth [PPD] ≤ 5 mm, no bleeding on probing/suppuration (SUP), no further radiographic bone loss). Patient site-specific comfort was scored using a visual analog scale (VAS). Descriptive statistics was carried out to assess the changes along the study period. Outcomes are reported in terms of mean values (5%-95% percentile values). Results: All the clinical variables substantially changed from T0 through T2. In particular, PPD decreased 3.7 mm (0.7-5.9) from T0 to T2. Likewise, the scores for the modified plaque index (mPI) and modified sulcular bleeding index (mBI) were reduced by 0.5 (−0.5-1.1) and 1.6 (0.4-2.4), respectively. SUP did not display at any implant site at T2 (59.2% implants in 29.2% patients suppurated at T0). Keratinized mucosa decreased 0.6 mm (−0.2-4.4) and while mucosal recession increased 2.5 mm (1.0-4.3). Alike, the radiographic parameters varied significantly from T0 through T2. Infrabony defects were filled by 2.2 mm (0.0-8.6) at T2 and marginal bone loss was reduced by 2.3 mm (−1.1-8.1). The mean VAS score significantly increased from T0 (56.7) through T1 to T2, reaching a score of 96 at T2. At this timepoint, 85.2% of the peri-implantitis lesions were resolved. Conclusions: The proposed surgical approach followed by submerged healing to reconstruct peri-implant bone defects may offer one therapeutic option for failing dental implants. Given the nature of the present study, its effectiveness in comparison to less invasive treatments needs investigation in randomized controlled trials.

Dental implants may be considered a reliable routine procedure in clinical practice for the replacement of missing teeth. Results from long-term studies indicate that implant-supported dental prostheses constitute a predictable treatment method for the management of fully and partially edentulous patients. Implants and their restorations, however, are not free from biological complications. In fact, peri-implantitis, defined as progressive bone loss associated to clinical inflammation, is not a rare finding nowadays. This constitutes a concern for clinicians and patients given the negative impact on the quality of life and the sequelae originated by peri-implantitis lesions. The purpose of this narrative review is to report on the prevalence of peri-implantitis and to overview the indications, contraindications, complexity, predictability and effectiveness of the different surgical therapeutic modalities to manage this disorder.
