Unlabelled: AIM. Identify the relationship between specific factors (age, sex, smoking, time of prosthesis in function, implant location, and width of peri-implant keratinized mucosa) and peri-implant diseases in patients from the Center of Research and Continuing Education in Implant Dentistry (CEPID) at the Federal University of Santa Catarina (UFSC), Brazil.
Materials And Methods: A cross-sectional study was conducted in 193 patients that had received 725 external-hexed cylindrical implants supporting functional prosthesis for at least 1 year (range from 1-9 years). Clinical examination included probing depths, bleeding on probing and/or suppuration. Radiographic exam was conducted to measure peri-implant bone levels.
Results: There was no statistically significance in the association between prevalence of peri-implant diseases and age, sex, time with prostheses in function and implant location variables independently. There was a statistically significant association between the independent variables of smoking and the width of keratinized peri-implant mucosa less than 2mm, and the presence of peri-implant diseases. When all the categories were evaluated together in relation with the peri-implant diseases, the prostheses in function for 5 years and more had association with presence of both, peri-implant mucositis an peri-implantitis. Peri-implantitis prevalence was higher for males with the prostheses in use for 5 years or more. Peri-implant mucositis was more associated with the participants over 57 years of age, with systemic disease and with the prostheses in function for more than 5 years.
Conclusions: Smoking habits and the width of peri-implant keratinized mucosa as independent variables were associated with the prevalence of peri-implant diseases.

Clin Oral Implants Res

Research Centre for the Study of Periodontal and Peri-Implant Diseases, University of Ferrara, Ferrara, Italy.
Objective: To evaluate the effectiveness of Sub-periosteal Peri-implant Augmented Layer (SPAL) technique performed with deproteinized bovine bone mineral (DBBM), delivered either as particulate (pDBBM) or block (bDBBM), in correcting a peri implant bone dehiscence (PIBD). Implants showing a thick (≥ 2 mm) peri-implant buccal bone plate (PBBP) at placement were also examined.
Material And Methods: Patients with a PIBD ≥ 1 mm, treated with SPAL with either pDBBM (SPAL) or bDBBM (SPAL), and patients with an implant showing a PBBP ≥ 2 mm at insertion (CONTROL) were included.
Outcomes of Surgical Treatment of Peri-Implantitis: A Retrospective Cohort Study.
Int J Oral Maxillofac Implants
January 2025
Purpose: The available scientific evidence on the effectiveness of the surgical treatment of peri-implantitis is limited. The aim of this study was to assess the risk of recurrence or disease progression in patients with peri-implantitis that underwent surgical treatment.
Materials And Methods: A retrospective cohort study was carried out in patients subjected to peri-implant surgery between 2015 and 2021, and with a minimum follow-up of 12 months.

Objective: To evaluate the effects of tinidazole (TNZ) combined with minocycline (MINO) on therapeutic effectiveness, bone resorption, and inflammation in peri-implantitis (PI).
Methods: This retrospective study included 96 PI patients admitted between January 2023 and February 2024. Patients were divided into a control group (n = 46) treated with MINO and a research group (n = 50) treated with TNZ plus MINO.

Aim: To propose a modified method for establishing a peri-implantitis murine model, assess the gene expression profile and immune cell infiltration of the gingiva and alveolar bone, and evaluate the transcriptomic similarity between patients with peri-implantitis and the corresponding murine model.
Materials And Methods: A ligature-induced peri-implantitis murine model was established using an immediate implant placement approach. RNA sequencing was performed to determine the transcriptomic profiles of peri-implant tissues from mice, patients with peri-implantitis and healthy individuals.

Background: Crown cementation is a common technique for implant-supported prosthodontics. However, for possible slipping of the cement below the mucosal margin, its thorough removal poses some issues. The objective of this study was to evaluate the presence of submucosal cement residues in patients with peri-implant disease by endoscopic visualization and to investigate the potential correlation between the pathological scenario and the spatial position of cement residues.
