View clinical trials related to Alveolar Bone Loss.
Filter by:The purpose of this clinical and radiographic study will be to determine what influence on marginal bone loss has the thickness of soft tissues and the height of the prosthetic abutment and eventually determine which of the two factors is the most important.This research was designed as a multicentre cohort study. Two clinical centers will treat patients through the placement of a single dental implant. The implants will be prosthetically loaded about 4 months after placement and periapical radiographs will be acquired at each time-point.
The present study is an effort to investigate the hypothesis that Platelet Rich Fibrin/Biphasic Calcium Phosphate may play a role in inhibiting osteoclasts differentiation and in bone loss.
Aim: dis double-blind split-mouth clinical trial study was performed to evaluate teh clinical and radiographic effect of local delivery of lovastatin gel as an adjunct to scaling and root planning (SRP) in teh treatment of chronic periodontitis. Method and Materials: 15 patients with two mandibular molar teeth with probing depth (PD)≥3 mm, clinical attachment level (CAL)≥3 mm and bone loss more than 3 mm according to parallel periapical x-ray and distance from CEJ to alveolar crest, were selected.Totally 24 mandibular molars were selected for teh study. Clinical periodontal parameters included PD, CAL, bleeding index(BI), plaque index(PI) were recorded for teh selected teeth at baseline and at 1,3 and 6 months. Radiographic assessments were performed at baseline and after 6 months. At one side teh pockets around randomly selected molar were injected with a blunt syringe filled with lovastatin gel 1.2%( case group=B), and on teh other side, teh pockets were filled with a placebo gel by a blunt syringe ( control group=A).Two-way repeated measure ANOVA test and T-test were used for statistic analysis Spss 23.( P<0.05) was considered significant.
A prospective randomized controlled trial of 30 patients from the Faculty of Dentistry of the UFJF was conducted. It was included patients who presented indication of extraction of premolars, canines or incisors. All the thirty patients underwent dental extraction and were randomly divided into three groups according to the study methodology. Plaster casts and Cone-Beam Computed Tomography (CBCT) exams were performed for comparative analysis between sample groups and between study times ( imediate postoperative and four months later).
The purpose of this pilot study is to conduct a interventional prospective clinical trial to evaluate the efficacy of three different xenografts for ridge preservation by comparing the quality of newly formed bone using histomorphometric and micro CT analysis.The three xenograft materials under investigation are Bio-Oss® (bovine derived xenograft), Equimatrix® (equine derived xenograft), and Endobon® (bovine derived xenograft). There are no prospective studies comparing the effectiveness of these three materials, Bio-Oss®, Endobon® and Equimatrix®, when placed in extraction sockets. Participants will be recruited from patients in the TUSDM clinics that require extraction of single rooted non-molar tooth and are treatment planned to receive dental implants in the future. Participants will be randomized to receive one of the three xenograft materials after tooth extraction. The percentage of newly formed bone and bone density will be compared between the three materials 4-6 months after ridge preservation.
Vitamin D has become important for periodontal disease due to play a role in autoimmunity, bone mineral metabolism and inflammation. Our aim was to investigate the relation between serum 25-hydroxy vitamin D levels, clinical periodontal parameters and blood serum biomarkers. The subjects were evaluated in 2 groups as chronic periodontitis (n= 30) and periodontally healthy subjects (n= 30). Periodontal parameters and fasting venous blood samples were taken from the subjects to assess each patient's periodontal status and for biochemical analyses (25-hydroxy vitamin D (25-OH vit D), osteoprotegerin (OPG), receptor activator of nuclear kappa B ligand (RANKL), C-telopeptide (CTx), tumor necrosis factor-α (TNF-α)).
The aim of this observational study is the evaluation of marginal bone remodeling after surgical implant placement, correlating the gingival thickness with the bone resorption rate.
This is set as prospective clinical trial to correlate histologically and radiologically the performance of four different bone grafts (synthetic hydroxyapatite alone, synthetic hydroxyapatite mixed with polylactic-polyglycolic acid, synthetic hydroxyapatite with i-PRF and inorganic bone graft) in the sinus floor elevation technique with lateral approach for the treatment of atrophic crests.
The present study was compared the level of alveolar bone loss, clinical parameters and IL-1β in PICF in one- or two-stage surgical procedures. Half of the patients were performed tissue level implant while other half were performed bone level implant.
The purpose of the study is to determine the effect of enamel matrix protein derivative on an inflamed, periodontal-involved tooth. The hypothesis to be studied is that enamel matrix derivative protein with increase the clinical attachment level is localized sites of advanced periodontal disease.
