PURPOSE This systematic review aimed to assess the available literature for regenerative treatment of peri-implantitis using bone graft substitutes and membranes. METHODS A search in electronic databases was conducted to assess all types of clinical studies treating bone defects derived from peri-implantitis using guided bone regeneration (GBR) techniques. RESULTS During the first screening...

This study is to investigate the subgingival bacterial diversity and community structure in the Uygur subjects with peri-implantitis.Totally 40 cases of gingival crevicular fluid were collected from Uygur subjects and divided into the Control group (healthy implants) and Case group (peri-implantitis), respectively. DNA was extracted, and the sequencing in the 16SrRNA V4-V5 region was conducted ...

AIM To monitor over 12 months clinical and radiographic changes occurring after adjunctive local delivery of minocycline microspheres for the treatment of peri-implantitis. MATERIAL AND METHODS In 25 partially edentulous subjects, 31 implants diagnosed with peri-implantitis were treated. Three weeks after oral hygiene instruction, mechanical debridement and local antiseptic cleansing using 0....

OBJECTIVE The aim of this in vivo study was to evaluate two different types of implant-abutment connections: screwed connection and cemented connection, analyzing peri-implant bacteria microflora as well as other clinical parameters. PATIENTS AND METHODS Twenty implants were selected, inserted in 20 patients, 10 with a screwed implant-abutment connection (Group 1) and 10 with a cemented impla...

OBJECTIVE Periodontal pathogens in dental plaque are the main causative agents of periodontitis and peri-implantitis. Detection of the presence of such periodontal pathogens early would serve as a useful tool in the diagnosis and treatment of this disease. Therefore, the purpose of this study was to investigate whether the periodontal pathogen levels in saliva were correlated with the periodont...

The purposes of this study is to evaluate the prevalence of peri-implant diseases; mucositis and periimplantitis of patients received dental implant at Riyadh city, KSA. In addition to the assessment of the relationship between peri-implant diseases and other related risk factors such as plaque accumulation, smoking, diabetes, and overall periodontal condition. A cross-sectional study was carri...

RESULTS: At 6 and 12 months, Class Ie defects tended to reveal higher changes in the mean probing depth (PD) and clinical attachment level (CAL) values when compared with Class Ib and Class Ic groups. However, significant differences were only observed at 6 months (PD: 2.9 +/0.3 versus 1.4 +/0.5 versus 1.3 +/0.7 mm; CAL: 2.5 +/0.5 versus 0.9 +/0.8 versus 0.9 +/0.7 mm). Site-level analysis has p...

Introduction: The aim of this study was a retrospective clinical evaluation of the long-term prevalence of peri-implant diseases associated with a modern rough-surface dental implant system. Materials and methods: A total of 237 implants were inserted in 47 patients between 1994 and 2005. Peri-implant parameters (sulcus bleeding, pocket depth and bone loss) were evaluated at a mean of 9.1 years...

objectives: this study aimed to compare the diagnostic accuracy of inverted and unprocessed digitized periapical radiographs for detection of peri-implant defects. materials and methods: a total of 30 osteotomy sites were prepared in three groups of control, study group 1 with 0.425 mm defects and study group 2 with 0.725 mm defects using the sic and astra tech drill systems with 4.25mm and 4.8...
