PURPOSE Tissue reactions to 4 different implant surfaces were evaluated in regard to the development and progression of ligature-induced peri-implantitis. MATERIALS AND METHODS In 6 male mongrel dogs, a total of 36 dental implants with different surfaces (9 titanium plasma-sprayed, 9 hydroxyapatite-coated, 9 acid-etched, and 9 commercially pure titanium) were placed 3 months after mandibular ...

BACKGROUND The purpose of this pilot study was to evaluate the healing potential and reosseointegration in ligature-induced peri-implantitis defects adjacent to various dental implant surfaces following lethal photosensitization. METHODS A total of 36 dental implants with 4 different surface coatings (9 commercially pure titanium surface [CPTi]; 9 titanium plasma-sprayed [TPS]; 9 hydroxyapati...

OBJECTIVES The aim of this sub-analysis of two prospective studies was to assess the incidence of peri-implant mucositis and peri-implantitis in fully edentulous patients with an implant-retained mandibular overdenture during a 10-year follow-up period. MATERIAL AND METHODS One hundred and fifty edentulous patients with two endosseous implants to support a mandibular overdenture were availabl...

BACKGROUND Progressive peri-implant bone losses, which are accompanied by inflammatory lesions in the soft tissues, are referred to as peri-implantitis. The aim of this study was to compare the effects of photodynamic therapy (PDT) and conventional technique on microbial reduction in ligature-induced peri-implantitis in dogs. METHODS Eighteen third premolars from nine Labrador retriever dogs ...

Osseointegrated implants provide predictable restorative support for crowns, restorations, prosthesis abutments, and removable dentures. Their widespread use in recent years has produced different types of complications. Retrograde peri-implantitis, a lesion occurring at the periapical area of an osseointegrated implant, has recently been described. This paper presents a series of reports descr...

The purpose of this study is to evaluate the outcome regenerative therapy peri-implantitis. 32 patients involved in with inflammatorydestructive processes field peri-implant tissues osseointegrated implants. diagnostic parameters used for assessing peri-implantitis include clinical indices, Probing Pocket Depth (PPD), Bleeding On (BOP), periimplant radiography. 16 implants mucositis, 8 early an...

in inflammatory diseases such as peri-implantitis (pi) and chronic periodontitis (cp) both adaptive and innate immunity play a part. natural resistance associated macrophage protein 1 ( nramp1 ) has considerable effects on macrophage function (phagocytosis) and host innate immune response against infections. the present study was to investigate the relationship of nramp1 gene polymorphisms with...

background. orthodontic mini-implants provide skeletal anchorage for tooth movement. there are two designs of mini-implants, tapered and cylindrical, which exhibit different clinical characteristics, including possible micro-damage to cor-tical bone. complications such as peri-implantitis and pain after mini-implant placement are common. the aim of this study was to evaluate the effect of mini-...

Inflammatory infiltrate may be important in the evolution of inflammatory processes involving peri-implant tissues. Angiogenesis is an important feature of inflammation and healing, but its role in the development and progression or in the healing of periodontal lesions has not been elucidated. Vascular endothelial growth factor (VEGF) is a potent inducer of endothelial cell proliferation. The ...
