Active clinical trials for "Peri-Implantitis"

Patients included in the study will be recruited after arriving at the Faculty of Dentistry of the University of Zagreb. During the clinical examination, the patient's periodontal status (bleeding during probing, and the depth of the pockets around the implant) and a control x-ray will be taken to check bone loss. Saliva sampling will occur at 3-time points, when establishing the diagnosis of periimplantitis, before the start of therapy, and at the first control after treatment.

In the present study, investigators, aimed to evaluate the effect of erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser application combined with mechanical debridement (MD) on clinical parameters and biochemical parameters such as receptor activator of nuclear factor-kappa B ligand (RANKL) and osteoprotegerin (OPG) in patients with peri-implant diseases.

The objective of this randomized controlled clinical trial is to evaluate the outcome of treatment of peri-implantitis with or without systemic antibiotics. Specific aims are to analyze (i) the effect of systemic antibiotics and local antiseptics on the healing process, and (ii) the risk for recurrence of disease following surgical treatment of peri-implantitis.

The aim of this study was to evaluate the influence of a triclosan-containing toothpaste in the profile of osteo-immunoinflammatory mediators in the peri-implant crevicular fluid (PICF) and in the clinical parameters during the progression of experimental peri-implant mucositis.

The aim of this study was to evaluate the effect of using a synthetic bone substitute with or without simvastatin on regenerative surgical treatment of bone defects associated with peri-implantitis in a 6- months randomized controlled clinical trial. A total of 30 patients diagnosed with peri-implantitis were randomly assigned to one of two surgical treatment groups (group I: synthetic bone substitute (NanoBone), group II: NanoBone with simvastatin). Clinical measurements included probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), modified sulcus bleeding index (mSBI) and mucosal recession (MR). Radiographic bone fill was evaluated at baseline and after 6- months.

Implant placement in the posterior maxilla is compromised due to atrophy of the alveolar process and maxillary sinus pneumatisation. Bone augmentation is frequently necessary before or in conjunction with implant placement. The most commonly used method to augment the posterior maxillary involves maxillary sinus floor augmentation (MSFA) with autogenous bone graft or bone substitute. Autogenous bone graft harvesting is associated with risk of donor site morbidity and unpredictable resorption of graft. Thus, bone substitutes alone or in combination with autogenous bone are used increasingly to simplify the surgical procedure. Symbios biphasic biomaterial is a resorbable inorganic bone forming material derived from red algae consisting of 20% hydroxylapatite and 80% β-tricalciumphosphate with osteoconductive properties. Histologic and radiographic examinations indicate that β-tricalciumphosphate is slowly resorbed and replaced with bone. MSFA with β-tricalciumphosphate alone or in combination with autogenous bone or other bone substitutes have demonstrated high implant survival and new bone. Symbios xenograft granules is a porcine bone mineral with osteoconductive properties. Histologic and radiographic examinations indicate that xenograft is a non-resorbable graft material. MSFA with xenograft alone or in combination with autogenous bone have shown high implant survival and new bone. The objective is to test the H0-hypothesis of no difference in implant outcome after MSFA with autogenous bone graft or in combination with Symbios biphasic biomaterial or Symbios xenograft. 60 consecutively healthy patients with a missing posterior maxillary tooth/teeth will be randomly allocated to: 1) MSFA with autogenous bone graft, 2) MSFA with mixture of 50% autogenous bone graft and 50% Symbios biphasic biomaterial 3) MSFA with mixture of 50% autogenous bone graft and 50% Symbios xenograft. Implants will be inserted simultaneously with MSFA. Clinical and/or radiographical evaluation using periapical radiographs and Cone Beam Computer Tomography will be performed preoperatively, immediate postoperatively, before abutment connection, after prosthetic rehabilitation, and after one year to assess the treatment outcome and volumetric changes of the augmented area. Outcome include survival of suprastructures and implants, volumetric stability of graft, peri-implant marginal bone level, oral health related quality of life, and complications.

the aim of the study is to compare between two non-surgical methods of treatment of peri-implantitis by using debridement and placing an healing abutment with electomagnetic field (MED-Magdent Miniaturized Device) in the test group and Sham healing abutment in the control group ( Sham MED).

In this study, the effect of photodynamic therapy (indocyanine green mediated) on the clinical, biological and inflammatory aspects was assessed in diabetic patients having peri-implantitis

In this study, 940 nm diode laser and 2780 nm erbium, chromium doped: yttrium, scandium, gallium, garnet (Er, Cr: YSGG) laser were used in the non-surgical treatment of peri-implant diseases in addition to mechanical treatment. And the effects of dental lasers on clinical parameters and matrix metalloproteinase 9 (MMP-9) and tissue inhibitors of matrix metalloproteinases-1 (TIMP-1) levels in peri-implant crevicular fluid were evaluated.

The current study aimed to investigate the effect of the combined Nd-Er: YAG laser on the surgical treatment of peri-implantitis by evaluating clinical markers and biomarkers of bone loss (RANKL/OPG). Twenty (20) patients having at least 1 implant diagnosed with peri-implantitis were randomly assigned to two groups for surgical treatment. In the test group (n=10), Er: YAG laser was used for granulation tissue removal and implant surface decontamination, while Nd: YAG laser was employed for deep tissue decontamination and biomodulation. In the control group (n=10), an access flap was applied, and mechanical instrumentation of the implant surface was performed by using titanium curettes. The following clinical parameters were evaluated at baseline and six months after treatment: Full-mouth Plaque Score (FMPS), Probing Pocket Depth (PPD), Probing Attachment Levels (PAL), recession (REC), and Bleeding on probing (BoP). Peri-implant crevicular fluid (PICF) was collected at baseline and six months for the evaluation of soluble RANKL and OPG utilizing enzyme-linked immunosorbent assay (ELISA).
