Filter by:The objective of this prospective clinical study was to evaluate the 3-year outcomes of anti-infective surgical treatment of peri-implantitis when a regular supportive peri-implant therapy (SPIT) programme was followed.
Photodynamic therapy (PDT), also known as photoradiation therapy, phototherapy, or photochemotherapy, involves the use of a photoactive dye (photosensitizer) that is activated by exposure to light of a specific wavelength in the presence of oxygen. In recent years, PDT has been introduced as an important novel disinfection therapy in the field of implant dentistry. The inactivation of microorganisms using PDT has been defined as antimicrobial PDT. PDT has the potential to be an alternative of antibiotics, especially for the treatment of localized infections and oral biofilm. PDT is unlikely to cause bacterial-resistance and is equally effective against antibiotic-resistance and antibiotic-susceptible bacteria. Inconsistent results have been reported regarding the potential role of PDT as an adjunct to mechanical debridement in the management of peri-implant infection. Thus, the aim of the present trial is to investigate the treatment effect of non-surgical treatment with and without photodynamic therapy on initial peri-implantitis.
In the field of periodontics, periodontal support therapy has proven to be essential in preventing the incidence or recurrence of periodontal diseases. The protocol is designed according to the risk profile of a patient. For example, in the presence of the history of periodontal therapy, subgingival microbiota containing large numbers of spirochetes and mobile rods can recolonize pockets 4-8 weeks after scaling. Similarly, routine maintenance of dental implants has been recommended to prudently avoid peri-implant inflammation, Indeed, the understanding of the nature of the tissue around the implant and its pattern of disease would be important to consider, even surpassing importance. Recently, a systematic review by our group has identified the importance of maintenance therapy around implants because it can help prevent about 3 times patient-level frequency peri-implantitis. Henceforth, our primary goal was to study the influence in a cross-sectional study of the frequency of peri-implantitis patients according to their post-implant placement and corresponding prosthesis visits supportive peri-implant maintenance. As such, it will be shown: 1. What are the local and systemic factors affecting the appearance of peri-implantitis 2. The ideal frequency of supportive peri-implant maintenance in patients who do not develop peri-implant disease 3. What is the population of patients who come to supportive peri-implant maintenance after placement of dental implants
The general aim of this project is to investigate the long-term treatment outcome after implant therapy. The patients' satisfaction with implant treatment will be studied and correlated to biological and technical problems. The survival rates of implants at patient level and the degree of bone loss of remaining teeth and implants will be calculated. The levels of cytokines and bone loss markers in peri-implantitis sites and periodontal defects and at healthy sites will be analyzed in order to study the correlation between cytokine and bone loss marker levels, and clinical conditions. Independent variables which could be regarded as significant risk factors or risk predictors on the incidence of peri-implantitis are aimed to be identified
Recent data found that peri-implantitis may differ from periodontitis at the histological level in terms of extent and composition of the cellular components. From human biopsies, it has been shown a deeper apical extension of the inflammatory cell infiltrate and a larger proportion of granulocytes and macrophages in peri-implantitis lesions compared to periodontitis lesions. Following experimental peri-implantitis, it has been observed a continuing bone loss around dental implants after ligature removal; whereas, such a progression was not observed around teeth after cessation of the experimental periodontitis. The factors influencing the recruitment and the activation of osteoclasts in both diseases have not been compared yet. Hypothesis : The more rapid and more severe alveolar bone destruction occurring in peri-implantitis compared to periodontitis is due at least in part to differences in the inflammatory process in these diseases. Aim: to study the cytokine profile produced by gingival explants from periodontitis or peri-implantitis sites and to test the consequences on alteration of bone remodelling activity using in vitro approach. Materials and methods The investigators will establish a collection of human gingival samples from patients undergoing surgical treatment of periodontitis or peri-implantitis. The investigators will test pro-inflammatory cytokines and chemokines release and consequences on osteoclast differentiation and activity.
The primary purpose of this study is to determine what effect, if any, do different dental materials used to seal the prosthetic screw channels of implant supported restorations have on dental implant health parameters and microbiology.
This study is designed to assess the safety and effectiveness of BonyPid-500TM implantation for intrabony peri-implantitis defects. BonyPid-500™ is a bone graft substitute, which contains an antibiotic drug - doxycycline, and is intended for filling and reconstruction of bone defects caused by peri-implantitis.
This studies aims to investigate the effect of a probiotics in peri-implantitis patients as an adjunct to non-surgical therapy.
The purpose of the study is to evaluate if surgical treatment of peri-implantitis with enamel matrix derivative (Emdogain®, EMD) will have an additional effect on the healing outcome, changes in the peri-implant microflora and on the inflammatory response in the periimplant pocket at 12 months.
The purpose of this randomized trial was to compare reconstructive surgery of advanced peri-implant intra-osseous defects with porous titanium granules (PTG/Test) to open flap debridement (OFD/Control) in a non-submerged technique over 6 months.
