Active clinical trials for "Peri-Implantitis"

This study focuses on evaluating the success of different treatment methods for peri-implantitis (gum disease around implants) and to understand the factors that might affect the success of the treatment provided.

The aims of the current study are 1) to assess the therapeutic resolution of the peri-implantitis after resective surgical treatment with or without implantoplasty procedure (no further radiographic bone loss, no erythema of the peri-implant mucosa, PD <6mm), and 2) to evaluate the survival rate of the peri-implantitis treated dental implants.

The objective of this prospective clinical study was to evaluate the 3-year outcomes of anti-infective surgical treatment of peri-implantitis when a regular supportive peri-implant therapy (SPIT) programme was followed.

The aim of this study was to evaluate the early and late implant loss rate in a sample of patients who had received implant-supportive restorative therapy in a university setting. Moreover, the study aimed to identify patient- and implant-related variables for implant failure

Objective: This study investigated how patients' knowledge, attitude, and perceptions influence their oral hygiene practices as well as peri-implant health. Materials and Methods: Participants with single implant crowns placed in 2007-2011 completed a questionnaire that examined their knowledge, attitude, and perceptions on oral hygiene practices and peri-implant health before receiving a periodontal examination, prophylaxis, and oral hygiene education. Clinical parameters recorded were peri-implant probing depths and plaque index, width of keratinized mucosa, implant crown characteristics, reason for tooth loss, and diagnosis of peri-implant health.

Objectives: This study aimed to assess the prevalence of peri-implantitis in human im-munodeficiency virus (HIV) -positive patients and the presence of a possible correlation between the immunological profile and serological values, of peri-implantitis, and of pos-sible differences between all-on-4 and single crown/bridge prostheses. Subjects and methods: This retrospective study included 58 adult HIV-positive patients (222 implants) with either all-in-4 prostheses or single crowns/bridges on at least one dental implant loaded for more than a year who were followed for at least one year. Data pertaining to the probing pocket depth (PPD), bleeding on probing, and immunological and systemic profile were collected. Results: Patients with single crown/bridge implant rehabilitation showed higher preva-lence of peri-implantitis (34%) than patients with all-on-4 rehabilitation (0%) (p=0.012). Patients with all-on-4 rehabilitation were significantly older than those with single crowns/bridges (p=0.004). Patients with peri-implantitis had implants for a significantly longer duration than those without (p=0.001), implying that the probability of peri-implantitis increases as the age of implant increases. Conclusions: The prevalence of peri-implantitis was 26% in HIV-positive patients and 8% in dental implants. No correlation was found between patients' immunological and se-rological factors and peri-implantitis. The most important risk factor for peri-implantitis and mucositis was implant age.

The scientific evidence available at present regarding the alterations suffered by the alveolar ridge after the explantation of implants that have been considered to be abandoned due to periimplantitis, as well as the remaining sequelae from said treatment, is scarce and inconclusive. Regarding this background, it is speculated that the different types of peri-implant defects present different bone remodeling and different sequelae after the explantation of the implants affected by peri-implantitis. Thus, it has been hypothesized that the peri-implant defect configuration has an influence on the radiographic bone alterations that occur after explantation. In order to test this hypothesis, a retrospective study has been designed as it follows: Patients who have undergone implant placement procedure and suffer from peri-implantitis will be consecutively included in the study. In addition, patients should present at least 2 CBCTs taken before and after explantation, 4-6 months apart. Linear measurements will be taken in order to assess dimensional changes of the alveolar ridge at 1, 3, 5 and 7 mm from the bone crest.

900 subjects having received dental implants 9-10 years ago are invited for a clinical and radiographic examination. The individuals were randomly selected from the National Health Insurance data register in Sweden. The clinical and radiographic examination of the 900 selected subjects will include assessments of implant loss, loss of prosthesis and technical / biological complications. Biological complications will be assessed from the findings in the clinical and radiographic examinations. Thus, signs of pathology in peri-implant tissues, probing pocket depth (PPD) and bleeding/pus on probing (BoP) will be recorded. Marginal bone loss and other findings in radiographs will also be evaluated. The prevalence, extent and severity of peri-implantitis will hereby be determined. Patient-centered outcomes will also be obtained.

Aim: A study was made of the prevalence, co-occurrence and association among caries, nutritional habits and peri-implant disease, with an analysis of the influence of other patient and implant factors upon peri-implant disease. Material and methods: The included subjects underwent a clinical examination and were asked to complete a questionnaire. Demographic data and potential lifestyle/behavioral variables were collected. Clinical and radiographic assessment allowed calculation of the decayed, missing and filled teeth (DMFT) index and peri-implant diagnosis. Uni- and multivariate logistic regression analyses were applied to identify predictors of peri-implant disease.
