Filter by:This case series study aims to evaluate the local effects of Atorvastatin (which belongs to the family of lipid-lowering drugs, known as statins) combined with β-TCP (which is a synthetic osteoconductive bone graft), on the volume of the residual bone defects and on hastening the bone regeneration after radicular jaw cyst enucleation using CBCT-based volumetric analysis to calculate the shrinkage rate of these defects.
The Cohort on Plant-based Diets (COPLANT) study is a multi-centre cohort study that starts baseline recruitment from 2024 to 2027 with approximately 6,000 participants in Germany and Austria. The COPLANT study focuses on vegan (no animal products), vegetarian (no meat and fish, but dairy products and eggs), pescetarian (no meat, but fish) and omnivorous (mixed diet including all possible animal products) diets. The aim of the COPLANT study is to gain new insights on health benefits and risks as well as social, ecological and economic effects of different plant-based diets in comparison to a mixed diet. In addition to a detailed dietary survey using an app adapted to the needs of this study, the baseline examination includes measurements of body composition, bone health, cardiovascular risk factors, diabetes risk, contaminants and lifestyle. For the basic laboratory program, fasting blood, 24-hour urine collection and a stool sample are taken from all study participants. Furthermore, specific aspects of dietary behavior, physical activity and other lifestyle factors are collected via questionnaires. Follow-up studies are planned at intervals of 5, 10 and 20 years after the baseline visit.
Nutrients important to bones. Because bones undergo continuous remodeling, an adequate supply of nutrient substrate is needed to support the formation phase of bone remodeling. In addition to their passive roles as substrate for bone formation, dietary calcium and protein play active roles in bone metabolism, as well as phosphorus and vitamin D. Other vitamins and minerals are also needed for metabolic processes related to bone, directly or indirectly.
Clinical and Radiographic Evaluation of the Effect of Hyaluronic Acid Surface Treatment Versus Sandblasted Acid Etched on Stability of Delayed Dental Implant in Posterior Maxilla.
Evaluation of the effect of hyaluronic acid with hydroxyapatite versus hydroxyapatite alone on bone regeneration following enucleation of mandibular odontogenic cyst.
comparing socket shield technique with early implant placement with contour augmentation in preserving the bone contour
The aim of the study is to evaluate the crestal bone loss developed around short dental implants after using screw retained Hybrid ceramic crowns when compare to screw retained Lithium Di silicate based ceramic crowns.
When a dental extraction is performed, sequential cascade of events happens that lead to a modeling and remodeling of the area. This phenomenon leads to bone resorption and consequential volume loss atrophy. In literature several biomaterials (Autogenous, alloplastic, allografts and xenografts) were tested as alveolar fillers with the aim of controlling this physiologic event. Socket preservation is today a very widely spread dental technic to preserve the alveolar dimensions, that uses a wide range of biomaterials. Alloplastic materials have a fair evidence to work in several regenerative procedures in the oral and maxillofacial region. This pilot trial aims to characterize Histologic bone healing pattern in a human socket preservation model of 2/3 biphasic calcium sulfate cement matrix's and Hydroxyapatite (HA granules). Alterations in Volumetric alveolar socket changes in a socket preservation clinical model will also be studied.
This study is seeking to evaluate the binding of a commercially-available, recombinant human osteoinductive growth factor, rhBMP-2, to a human blood derived product scaffold, enhanced Platelet-rich fibrin (E-PRF), and the release of such a growth factor over time in an in vitro (laboratory) environment. The investigators will compare these release kinetics to those of the FDA approved carrier for rhBMP-2, an absorbable collagen sponge (ACS), a combination of E-PRF and ACS, and E-PRF alone.
To compare between bifocal and trifocal external bone transport by ilizarov ring external fixator as a treatment method for posttraumatic bone defects more than 5cm in lower extremities regarding: - External fixation index . - The need of any further surgical procedures as debridement at docking site , the need of cancellous bone graft or the use of internal fixation. - Functional outcome, complication rate as well as limb length discrepancy.
