This study constructs a standard in vitro laser treatment platform with dental implant thread surface on bacterial adhesion for peri-implantitis at different tooth positions. The standard clinical adult tooth jaw model was scanned to construct the digital model with 6 mm bone loss depth on behalf of serious peri-implantitis at the incisor, first premolar, and first molar. A cylindrical suite co...

BACKGROUND The subcrestal placement of implant platform has been considered a key factor in the preservation of crestal bone, but the influence of implant placement depth on bone remodeling combined with peri-implantitis is not fully understood. The aim of this study was to assess the effect of the crestal or subcrestal placement of implants on peri-implant bone defects of ligature-induced peri...

Peri-implantitis is a state defined as an inflammatory reaction around osseointegrated implants, leading to progressive loss of supporting bone. Various treatment methods are suggested in the treatment of peri-implantitis and clinicians have to choose a method over a large number of treatment protocols. Lasers have shown promising therapeutic effect in treatment of peri-implantitis. However, so...

Evaluation of periodontal and peri-implant tissue condition is mainly based on clinical examination and imaging diagnostics. Some data imply that Metalloproteinase-8 (MMP-8) level examination in peri-implant sulcular fluid (PISF) might be useful for evaluating the condition of peri-implant tissues and monitoring a development of peri-implant inflammation, including both mucositis and peri-impla...

BACKGROUND The aim of this study was to evaluate the progression of experimental peri-implantitis in dogs using implants with different surface coatings. METHODS Thirty-six dental implants with four different surface coatings, commercially pure titanium (cpTi), titanium plasma sprayed (TPS), hydroxyapatite (HA), and acid-etched (AE), were placed in six mongrel dogs. Five months after implanta...

The presence of DNA of Actinobacillus actinomycetemcomitans, Porphyromonas gingivalis, and Prevotella intermedia in the peri-implant sulcus samples of 19 partially edentulous patients was analyzed by polymerase chain reaction (PCR) and related to the depth of the peri-implant sulcus, bleeding on probing, and probable risk of disease. Ten of those patients presented a history of periodontal dise...

AIM The purpose of the present study was to assess the cost-effectiveness of various alternatives of non-surgical peri-implantitis treatment. MATERIALS AND METHODS A decision analytical model was constructed and populated with parameter estimates from recent literature for reduction in pocket probing depth (PPD) in response to eight different treatment alternatives. A micro-costing approach c...

Peri-implantitis has been defined as an inflamematory condition involving dental implants, surrounding mucosa and bone, which lose supporting bone. Although high success rates for endosseous implants have been reported, failures occur, and some implants are lost or removed. At least 10% of the failures have been suggested to be the result of peri-implantitis. One of the major causes of the peri...

OBJECTIVE The aim of this case-control study was to compare patients with a healthy peri-implant environment and patients affected by peri-implantitis, evaluating the occurrence of antibodies to extracellular matrix (ECM) molecules. The authors hypothesized the presence of ECM autoantibodies in serum of peri-implantitis patients. MATERIALS AND METHODS Patients were divided into two groups: on...

At the turn of the millennium, marketing estimates indicated that over 2 million dental implants are installed annually, and this number is expected to rise further over the next few years. It is evident that the installation of oral implants is a routine procedure in the reconstruction of fully or partially edentulous individuals. Like natural teeth, the artificial abutments penetrate the oral...
