Filter by:Although the metal-ceramic system is still widely used to fabricate crowns and fixed partial dentures and is considered as the standard treatment in dentistry, aesthetic concerns have stimulated the development of new dental tooth-colored systems as PEEK. BioHPP PEEK is 20% ceramic reinforced, semicrystalline, thermoplastic and radiolucent polymer for extreme durability especially for frameworks for fixed and removable dental prostheses. It has many advantages as low density, light weight, shock absorber, biocompatible and venerable with composite resin. The aim of this study is to evaluate the clinical performance of milled BioHPP PEEK-based single crowns and compare them to metal-based single crowns.
The purpose of the research is to study a new safety monitoring system developed by SafelyYou to help care for a loved one with dementia. The goal is to provide better support for unwitnessed falls. The SafelyYou system is based on AI-enabled cameras which detect fall related events and upload video only when these events are detected. The addition of a Human in the Loop (HIL) will alert the facility staff when an event is detected by the system.
Vertebral body fractures are a major health care problem in all countries with incidence 1.4%. They are a common cause of severe debilitating pain, with consequent deteriorated quality of life, physical function and psychosocial performance. Surgery is indicated in patients with vertebral body fracture, and concurrent spinal instability or neurologic deficit. The cornerstone of management for vertebral body fractures without neurological impairment is medical therapy, which include analgesics, bed rest, orthoses and rehabilitation. In the majority of patients such treatment modalities are effective. However, conservative management measures are not indicated for every type of fracture. For example, in older patients with vertebral fractures and cardio-respiratory disease it is not possible to prescribe bedrest for long period. Moreover, sometimes anti-inflammatory drugs are poorly tolerated by older patients, and bed rest can lead to further demineralization of the vertebrae, predisposing to future fractures. Percutaneous minimally invasive vertebral augmentation methods for cement application into the vertebral body are a useful tool for the management of symptomatic fractures without neurological impairment when conventional measures of treatment can not be adopted. Two different percutaneous minimally invasive vertebral augmentation methods for cement application into the vertebral body for the management of symptomatic vertebral body fractures without neurological impairment have been developed, namely vertebroplasty and kyphoplasty. Kyphoplasty and vertebroplasty have gained wide acceptance worldwide to manage patients without neurological impairment suffering from unmanageable pain caused by vertebral body fractures. Both procedures depend on mechanical stabilization of the fracture produced by cement injection into the fractured vertebral body. Cement augmentation of the vertebral body by vertebroplasty and kyphoplasty was originally introduced for osteoporotic compression fractures, but surgeons have now applied these techniques as a method of enhancing anterior column support while avoiding the morbidity and complications associated with anterior approaches. The mainstay of the controversy between kyphoplasty and vertebroplasty are height restoration, whether or not this height restoration is clinically significant, and the risks related to height restoration.
In recent decades, some observational studies suggest that peripheral BP measured by brachial artery may not necessarily represent BP measured in the aortic artery which is known as central BP .In addition, some clinical trials also revealed that despite with comparable peripheral BP, patients with high central BP had significantly higher cardiovascular risk compared with those with low central BP indicating that central BP might be an independent predictor for CVD
Atrophic ridge augmentation utilizing guided bone regeneration (GBR) has become a major treatment option to provide optimal bone support for osseointegrated dental implants. GBR was initially employed to treat simple defects, including dehiscence and fenestration defects. In addition, GBR has been utilized for horizontal and vertical ridge augmentations and has demonstrated reproducible outcomes, with high implant survival rates and low complication rates. The results of recent clinical and histologic studies of ridge augmentation with GBR indicated that autogenous bone graft may be a suitable material for staged localized ridge augmentation in both horizontal and vertical augmentations. The main advantages of autogenous grafts are their osteogenic, osteoinductive and osteoconductive capabilities. Because of these qualities, autogenous grafts are considered by many to be the gold standard for bone regeneration
The study will identify the epidemiological and treatment profiles of acute peritonitis in Italy
The objective of this study is to test the technical feasibility of LapAR visualization system for guiding laparoscopic surgeries and to gather clinical feedback on the use of this tool.
Immediate tooth replacement with implants into extraction sockets has become a common clinical procedure regarding implant survival, osseointegration and esthetics. Basically, when there is a labial bone plate loss after extraction 2 stage GBR procedure would be carried out to allow adequate amount of bone formation to be reconstructed and receive the dental implant. The challenge is when there is a partial or complete loss of labial plate of bone resulting from severe trauma or chronic inflammation or vertical fracture affecting the periodontal attachment
Antibiotic prescribing for childhood acute respiratory tract infections (ARTIs), including acute otitis media (AOM), pharyngitis, sinusitis, bronchitis, and upper respiratory infection (URI), is common in the United States (US). In the outpatient setting, more than 50% of children diagnosed with ARTIs receive antibiotic prescriptions. Considering that the estimated US prevalence of pediatric bacterial ARTIs is 27% (with the remainder of ARTIs caused by viruses) this represents a substantial degree of antibiotic overuse nationwide. Another troubling trend in antibiotic prescribing for ARTIs in children is the increased reliance on broad-spectrum, second-line agents for bacterial ARTIs. Unwarranted use of antibiotics, especially broad-spectrum agents, has been associated with increased resistance among several strains of bacteria that commonly cause ARTIs, posing risks to both individuals and communities.
Chemotherapy is still the standard first-line treatment option for EGFR unmutated patients. After a randomized phase Ⅲ trial, BEYOND was presented the synergistic effect of progression-free survival(PFS) could be expected when chemotherapy is combined with Antiangiogenesis agent bevacizumab in China;Therefore,in this study, The investigators will investigate the efficacy and safety of Anlotinb combined With Pemetrexed and Cisplatin as first-line therapy in patients with chemotherapy-naive, stage IIIB or IV, non-squamous NSCLC without targetable EGFR or ALK genetic aberrations.
