OBJECTIVES:
The aim of this study was to evaluate the 5-year clinical and radiographic outcomes following reconstructive therapy of peri-implantitis lesions using mineralized dehydrated bone allograft and resorbable membrane in the nonsubmerged mode of wound healing.

Objectives To compare, using an ex vivo model, the biofilm removal of three surface decontamination methods following
surgical exposure of implants failed for severe peri-implantitis.
Materials and methods The study design was a single-blind, randomized, controlled, ex vivo investigation with intra-subject
control. Study participants were 20 consecutive patients with at least 4 hopeless implants, in function for >12 months and with
progressive bone loss exceeding 50%, which had to be explanted. Implants of each patient were randomly assigned to the

OBJECTIVE:
Metabolic syndrome (MetS) is defined as a spectrum of conditions associated with an increased risk of developing CVD and type 2 diabetes. MetS include: hyperglycemia, hypertension, visceral obesity, dyslipidemia with elevated values of triglycerides (TG) and low levels of HDL. The aim of this review is to provide current knowledge of the relationship between MetS, its components and peri-implant diseases.

Over the years, only few authors have studied the association of systemic conditions with peri-implantitis. The aim of this study is to detect frequency and severity of peri-implant diseases among an Italian population of patients affected by metabolic syndrome (MetS).METHODS:

Abstract
Background: Retrograde peri-implantitis (RPI) is a pathological entity with an unclear etiology (e.g., overheating during implant insertion, residual infection of the tooth replaced by the implant or the endodontic lesion of neighboring teeth) and an extremely low prevalence and has been scarcely investigated. Therefore, the aim of this cross-sectional survey was to evaluate the knowledge and attitude of Italian implantologists regarding RPI.

Background: Peri-implantitis is an inflammatory disease with an increasing diffusion rate which can affect the long-term survival of a prosthetic rehabilitation. The present study focused on the decontaminating efficacy of chlorhexidine and air polishing system with sodium bicarbonate powder against Candida albicans, a microorganism which seems to have a superinfecting opportunistic role in the pathology. The aim of the authors was to investigate and compare the effectiveness of these treatments, commonly used in clinical practice.

Objectives: The aims of this retrospective study were to report data on the prevalence of retrograde peri-implantitis (RPI) in a single-center in a 20-year observation period and to evaluate implant survival after surgical treatment. Materials and methods: A retrospective cohort study was conducted screening all patients who underwent implant treatment in a private practice. Patients were enrolled if they had one or more implants showing a radiolucency around the implant apex, without implant mobility.

Aim: To comparatively evaluate the outcomes of professionally administered plaque removal (PAPR) and photodynamic therapy (PDT) in the treatment for experimentally induced gingivitis (G) and peri-implant mucositis (p-iM). Materials and methods: Twenty systemically healthy patients, each contributing a single implant-supported unit in a posterior sextant and a tooth within the same quadrant, were selected. Patients underwent an experimental G and p-iM trial consisting of a 2-week period of undisturbed plaque accumulation and a 6-week resolution phase following treatment administration.

Several antiseptic agents have been proposed for the treatment of peri-implantitis as a complementary therapeutic strategy in addition to mechanical devices. The aim of this study was to compare six different antiseptics, as well as alternative formulations of the same chemical agent, with respect to their decontamination efficacy and impact on chemical properties of the implant surface.

Background: Prevalence of peri-implantitis is directly proportional to the time of
functional loading.
The aim of this retrospective study was to assess the survival and success rates as well
as the incidence of peri-implantitis among patients with a history of periodontitis and
among implants.
Material and Methods: We evaluated clinical records of periodontally compromised
patients treated between January 1998 and July 2002, with implants enrolled in a
supportive periodontal and peri-implant treatment (SPT) follow-up programme. The
