Peri-implant disease

Pier Paolo Poli, Marco CicciÃ, Mario Beretta, Carlo Maiorana
The clinical condition involving dental implants, characterized by soft tissue inflammation, bleeding, suppuration and rapid bone loss is widely known as peri implantitis. The main objective in the treatment of peri-implantis is to arrest the progression of the disease and at the same time to keep the dental implant in the mouth solving the inflammations signs of bleeding and pain. The aim of this paper is to highlight the effectiveness of the use of titanium brush and antimicrobial photodynamic therapy (aPDT) to decontaminate the implant surface, in association with regenerative procedures by means of autologous bone and demineralized bovine bone mineral (DBBM) in the treatment of peri-implantitis defects...

Dental implant surgery has developed to a widely used procedure for dental rehabilitation and is a secure and predictable procedure. Local and systemic risk factors can result in higher failure rates. Diabetes mellitus is a chronic disease that goes in with hyperglycemia and causes multifarious side effects. Diabetes as a relative contraindication for implant surgery is controversially discussed. Because the number of patients suffering from diabetes increases, there are more diabetic patients demanding implant procedures...

The dental implant is a predictable way of restoring fully and partially edentulous patients and has shown high success rate for managing a broad range of clinical conditions. Improving implant surfaces has revolutionized the osseointegration of implants and changed the focus of implant research from osseointegration more toward the risk factors associated with the failure of implants in the long-term.

We investigated the prevalences and risk factors for peri-implant diseases in Japanese adult dental patients attending a follow-up visit at dental hospitals or clinics as part of their maintenance program. This cross-sectional multicenter study enrolled patients with dental implants who attended regular check-ups as part of a periodontal maintenance program during the period from October 2012 through September 2013. Patients with implants with at least 3 years of loading time were included in the study. The condition of peri-implant tissue was examined and classified into the following categories: healthy, peri-implant mucositis, and peri-implantitis...

The placenta derives from one extra-embryonic lineage, the trophectoderm. In the peri-implantation murine blastocyst, mural trophectoderm cells differentiate into primary trophoblast giant cells (TGCs) while the polar trophectoderm overlying the inner cell mass continues to proliferate later differentiating into secondary TGCs. TGCs play a key role in developing placenta and are essential for a successful pregnancy. Investigation of transcriptional regulation of specific genes during post-implantation development can give insights into TGCs development...

Despite the increasingly high rate of implantation of pacemakers (PM) and cardioverter-defibrillators (ICD) in elderly patients, data supporting their clinical and cost-effectiveness in this age stratum are ambiguous and contradictory. We reviewed the data regarding the applicability, safety, and effectiveness of the conventional pacing, ICD and cardiac resynchronization therapy (CRT) in elderly patients. Although peri-procedural risk may be slightly higher in the elderly, the procedure of implantation of PMs and ICDs is still relatively safe in this age group...

BACKGROUND: Tumor necrosis factor-alpha (TNF-α) is a potent immune-inflammatory mediator involved in the regulation of bone resorption. The single nucleotide polymorphism G-308A in the TNF-α gene increases the level of this cytokine. This phenomenon is also related to several diseases. Although the association between TNF-α (G-308A) polymorphism and dental peri-implant disease has been investigated, results have remained controversial. Hence, we performed this meta-analysis to provide a comprehensive and systematic conclusion on this topic...

Peri-implant bone levels are influenced by pathologic and nonpathologic conditions. The understanding of peri-implant disease has evolved over the past several decades, and the classification of peri-implantitis has been limited to descriptions of disease progression or those involving soft and/or hard tissues (peri-implant mucositis or peri-implantitis). However, no classification system has been established based on etiology. The objective of this study was to identify various etiologies for peri-implantitis and to establish a classification system based on the pathogenesis...

OBJECTIVE: To evaluate the frequency of peri-implant diseases and factors associated with its occurrence. MATERIAL AND METHODS: One hundred and fifty-five patients with dental implants were evaluated in this cross-sectional study. Dental implants were clinically and radiographically evaluated to diagnose their peri-implant condition, according to Mombelli (Proceedings of the 3rd European Workshop on Periodontology, 1999, Quintessence, London). Associations between peri-implant diseases and independent variables (socioeconomic, demographic and periodontal characteristics) were evaluated through bivariate analysis with chi-squared and Fisher's exact tests, as well as by multiple logistic regression...

Subthalamic nucleus (STN) local field potential (LFP) recordings demonstrate beta (13-30Hz) band oscillations in Parkinson's disease (PD) defined as elevations of spectral power. The amount of attenuation of beta band power on therapeutic levels of high frequency (HF) deep brain stimulation (DBS) and/or dopaminergic medication has been correlated with the degree of improvement in bradykinesia and rigidity from the therapy, which has led to the suggestion that elevated beta band power is a marker of PD motor disability...

The biologic complication of peri-implantitis threatens the survival of dental implants that have successfully integrated and are in function. A list of seven risk factors associated with this disease was generated in 2006 at the Sixth European Workshop on Periodontology. These factors were based on the prevailing literature. Since then, modifications to this list have been considered whereby some of the original items suggested to be associated with periimplantitis would be deleted, while, in light of evidence-based information, newer, emerging risks may be included...
