Background and Aim: It has been shown that anaerobic and capnophilic bacteria play an important role in implant failure and loss. The present study is an in vitro research aimed to investigate the antibiotic resistance of Aggregatibacter actinomycetemcomi-tans (Aa) and Porphyromonas gingivalis (Pg) in peri-implantitis lesions of Iranian pa-tients and to find laboratory efficiency of some antibi...

AIMS Over the past decades, the placement of dental implants has become a routine procedure in the oral rehabilitation of fully and partially edentulous patients. However, the number of patients/implants affected by peri-implant diseases is increasing. As there are--in contrast to periodontitis--at present no established and predictable concepts for the treatment of peri-implantitis, primary pr...

OBJECTIVE To compare the adjunctive clinical effects in the non-surgical treatment of peri-implantitis with either local drug delivery (LDD) or photodynamic therapy (PDT). MATERIAL AND METHODS Forty subjects with initial peri-implantitis, i.e. pocket probing depths (PPD) 4-6 mm with concomitant bleeding on probing (BoP) and marginal bone loss ranging from 0.5 to 2 mm between delivery of the r...

Dental implants are the most common therapeutic approach for resolving tooth loss and damage. Despite technical advances in treatment, implant failure rates can be as high 23% with major cause of peri-implantitis: a multi-species bacterial infection. With an annual growth rate placements 8.78% per annum, caused by infection is significant oral general health issue. The rise antibiotic resistanc...

A lot of effort has been directed towards developing dental implant surfaces which in turn have seen the increased success rate of osseointegration. Peri-implantitis and peri-implant mucositis are inflammatory conditions of implants that can lead to implant failure. Monitoring and maintaining implant restorations is aimed at preventing these complications.

BACKGROUND The pathophysiology and pathology of peri-implantitis remain unclear; however, its similarity to periodontitis has been described. The evaluation of peri-implant tissue and the diagnostic criteria of peri-implant disease are not currently standardized as they are for periodontitis. In this study, we evaluated clinical parameters during the implant maintenance period to determine sign...

Peri-implantitis remains the major impediment to the long-term use of dental implants. With increasing concern over the growth in antibiotic resistance, there is considerable interest in the preparation of antimicrobial dental implant coatings that also induce osseointegration. One such potential coating material is fluorapatite (FA). The aim of this study was to relate the antibacterial effect...

Dental implants play an important role in restorative dentistry. However, the long term implant’s stability is subject on the integration between fixtures and the surrounding tissues. Microbia presented in the oral cavity seems to have a substantial impact on biofilm formation on newly placed implants (1). The natural flora of the mouth is composed of black-pigmented anaerobic bacteria includin...

The microbiome of peri-implantitis sites and healthy dental sites was determined in subjects with a history of periodontitis. Ten systemically healthy non-smokers received periodontal treatment before implant placement. Plaque samples were collected from four sites of one implant with peri-implantitis (bone loss ≥2mm; PPD ≥6mm; BOP/suppuration; >1year loading) and from one dental site per quadr...

PURPOSE This retrospective study evaluated the outcome of implant-retained overdentures (IODs) after 5-19 years of clinical function. MATERIALS AND METHODS A retrospective analysis of patient files was performed referring to 27 patients who received 36 IODs with 3 different bar designs (group A=prefabricated round bars, n=7; group B=one-piece anterior milled bars, n=20; and group C=two bilate...
