Filter by:The aim of this clinical trial is to compare serum concentration of bone intake proteins [ sex hormone-binding globulin (SHBG), cross linked C-telopeptide of type I collagen (CTX-I)] and muscle atrophy marker [creatine kinase (CK-MB)] between patients after the fracture of proximal femur and their age corresponding counterpart without the fracture. The main question it aims to answer is: • Is the higher concentration of bone intake proteins and muscle atrophy marker a predictive factor of proximal femur fracture? The part of participants (Group 1) will be hospitalized at the Department of Orthopaedics and Rehabilitation and will undergo a surgical treatment (open reduction of the fracture). The rest (Group 2) will be admitted to the Department of Internal Medicine. Participants of both Groups will have the blood sample test taken, to evaluate and compare the serum concentration of SHBG, CTX-I and CK-MB proteins.
The aim of this clinical trial is to investigate the effect of the OsteoStrong training method and the Individually Adapted and Combined Training on the bone health of older women with high fracture risk. Additionally, the aim is also to explore the participants' experiences of each training method. Participants will be randomised to either treatment arm A (OsteoStrong) or treatment arm B (Individually Adapted and Combined Training). Participants in both groups will train for nine months. Treatment arm A will train individually once a week and treatment arm B will train in a group twice a week. Both groups will have a training instructor who will supervise and give training instructions. Researchers will compare the groups to see the effects of the training methods on the participants' bone health among other outcome measures. The participants will be tested at baseline and post-intervention (9 months later).
This study aims to evaluate the relationship between the maxillary intra-osseous vascular canal thickness as measured by volumetric tomography and the amount of intra-operative bleeding during open sinus floor augmentation. A sample of patients will be selected, and their maxillary intra-osseous vascular canal thickness will be measured using volumetric tomography. Intraoperative bleeding will be recorded during open sinus floor augmentation. The data will be analyzed to determine if there is a correlation between the thickness of the maxillary intra-osseous vascular canal and intraoperative bleeding.
In this clinical trial the effect of the implant-abutment morphology (platform-switched vs platform matched) will be assessed in both soft tissue (soft tissue thickness) and hard tissue (marginal bone loss) outcomes. Several clinical predictors (initial implant position level, gingival biotype, abutment height and prosthetic emergence profile) will also be taken into account as modulating factors of the clinical outcome.
The aim of this study was to assess the efficiency of the computer-guided interpositional sandwich osteotomy for the vertical bone gain and effects on vital structures (inferior dental nerve bundle) compared to free hand interpositional osteotomies.
immediate implant placement versus socket shield approach
The aim of this study will be to compare the amount of marginal bone height changes between immediate and delayed loading for immediately inserted implants used as abutments of mandibular overdenture.
Minimally invasive procedures with the tunnel technique have been suggested to decrease patient post-operative discomfort and morbidity in oral bone regeneration. In the ridge augmentation tunnel technique, crestal incision and the release of the connective tissue are avoided in order to enhance the blood supply of the flap. This approach preserves the blood circulation and does not damage the periosteum The purpose of this study is to evaluate the clinical outcome of a minimally invasive technique for maxillofacial horizontal bone augmentation . performed by using a collagen dermal matrix, deproteinized bovine bone and hyaluronic acid. Collagen matrix is inserted into a sub-periosteal tunnel using microsurgical instruments. Deproteinized bovine bone in a hyaluronic acid carrier are placed and inserted repeatedly into the pocket and absorbable suture is used to close the vertical incision.
Occlusal prematurity leading to loss of vertical stopping points between teeth can lead to teeth over eruption creating abnormal contact area which favors food accumulation and plaque retention. All these factors can lead to gingival inflammation and bone loss which may be worsen by abnormal occlusal force. Thus, orthodontic evaluation and treatment with periodontic therapy is mandatory to achieve proper treatment. Aim of the work: To evaluate and compare clinically and radiographically between effect of guided tissue regeneration (GTR) followed by orthodontic intrusion versus orthodontic intrusion followed by GTR in treatment of over erupted tooth with angular bone loss
A randomized controlled clinical trial was conducted in the Oral Surgery Unit, Faculty of Medicine and Dentistry, University of Valencia. The research was carried out following the principles described in the Helsinki Declaration and the study was approved by the Institutional Review Board of the Ethics Committee of the University of Valencia (1937615). Fifty patients were included in the study according to the selection criteria.The osteotomies were randomized in two groups: the control group was performed under the high-speed drilling (800 rpm) with irrigation technique and the study group under the low-speed drilling without irrigation technique (50 rpm). The randomization tool was www.randomization.com.
