Filter by:Implant supported superstructure is necessary for long term success and durability of the implant itself in terms of stresses distribution and fracture strength capability.1 Stresses falling on an implant are too much greater than those applied on a tooth structure with a periodontal ligament offering a degree of elasticity. The important mechanical and physical properties of materials used for the fabrication of dental prostheses include adequate flexural and tensile strength and modulus of elasticity, maximum fracture resistance, optimal bond strength and adequate polishability.
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 .

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.
Subperiosteal implants were first introduced in 1940 and then used worldwide for the treatment of edentulous maxilla or mandible with advanced bone atrophy.
Background : Type 1 diabetes (T1D) is associated with an increased risk of fractures. The mechanisms accounting for this bone fragility are not yet fully understood. As T1D is often diagnosed in childhood or early adulthood, the lower bone mineral density (BMD) and deteriorated bone microarchitecture observed in T1D may reflect changes in the bone that occurred before or at the time of peak bone mass achievement. There is a lack of high-quality prospective studies to determine whether adults with T1D continue to lose BMD or deteriorate bone quality compared with controls. Moreover, while chronic hyperglycemia is a risk factor for fracture in T1D, it is unknown if better glycemic control affects bone outcomes. This prospective multicenter cohort study aims: (1) To compare the changes in the following outcomes over 4 years in adults with T1D and controls without diabetes of similar age, sex and body-mass index distribution: BMD by dual-energy X-ray absorptiometry (DXA) at the femoral neck, hip, spine, and radius, trabecular bone score (TBS) by DXA, and serum biochemical markers of bone turnover (BTMs); (2) To evaluate whether long-term glycemic control or the presence of a microvascular complication are independent predictors of the changes in BMD and TBS in people with T1D.
The clinical study aims to assess the osteogenic effects of Galibone+ in bone regeneration post-extraction of impacted mandibular third molars.
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.
This study evaluated the clinical and biochemical aspects of flap design in dental implant applications regarding implantation success and patient comfort. In this split-mouth randomized controlled clinical trial, a vertical releasing incision was made at the distal end of the crestal incision on the test side, and the control side received a crestal incision alone. Sixty-eight implants were placed in 17 patients. Peri-implant groove fluid was collected on postsurgical days 3, 7, 30, and 90; OPG and RANKL levels were assessed to determine bone formation and resorption around the implants. Cortisol levels were assessed in peri-implant groove fluid at postsurgical days 3, 7, and 14. Visual analog scale (VAS), and swelling measurements were taken postoperatively. Panoramic and periapical X-rays were obtained immediately post-surgery and at 3 months. No significant marginal bone loss difference was observed between the test and control sides at 3 months. The RANKL/OPG ratio, cortisol levels, VAS scores, and swelling scores were higher in the test vs. control sides. Overall, while the use of a vertical incision has advantages, such as increasing the visual field of the surgeon and improving the ease of the operation, this approach should be used only when necessary, given the disadvantages of increased bone resorption mediators in the peri-implant tissue and reduced postoperative patient comfort.
Bone mineral density is an important measurement to detect osteoporosis. The goal of this clinical trial is to compare bone mineral density measurements in CT examinations and DXA scans. The main question it aims to answer is: - How good is the measurement of bone mineral density in the new photon-counting CT in comparison to DXA - How can we optimize the CT scan for bone mineral density Participants will undergo: - Clinically indicated CT scan on day of inclusion - Study related DXA scan on a separate appointment
