Survival Rate of All Ceramic Restorations Treated With Air-Water-Blasting Protocol
SurvivalProsthesisThis study evaluates retrospectively the survival rate of all-ceramic restorations, cemented using AWB technique (test) compared to those cemented with conventional technique (control)
Osteopontin in Metastatic Breast Cancer Patients
SurvivalProsthesisOPN plays an important role in various aspects of malignancy, particularly those involved in tissue invasion and metastasis, and OPN levels have been associated with aggressive¬ness in several cancer types, including breast cancer. Tumor response to treatment is a predictor of prognosis and overall survival for cancer patient population the investigators assigned osteopontin as potential contributors in breast cancer.

Digital Technique to Analyze the Wear of Implants and Natural Tooth as Antagonist.
Dental Prosthesis FailureThe aim of this study was to describe a novel digital technique to analyze the wear of screw-retained implant-supported metal-ceramic dental prostheses and natural tooth as antagonist. Materials and methods: Ten patients were consecutively included to rehabilitate partial edentulism by dental implants. Both the screw-retained implant-supported metal-ceramic dental prostheses and the natural tooth as antagonist were submitted to a digital impression through an intraoral scan to generate a Standard Tessellation Language digital file preoperatively (STL1), at 3 months (STL2), and 6 months (STL3) follow-up. Afterwards, an alignment procedure of the digital files (STL1-STL3) was performed on a reverse engineering morphometric software and volume changes at the screw-retained implant-supported metal-ceramic dental prostheses and the natural tooth as antagonist were analyzed using Student's t-test. Moreover, Gage R&R statistical analysis was conducted to analyze the repeatability and reproducibility of the digital technique.

15 Years Outcomes Following Bioprosthetic vs Mechanical Aortic Valve Replacement Between 50-65 Years...
SurgerySurvival2 moreCurrently there is an increase in the use of bioprosthesis worldwide (> 70% according to national data of the Spanish Society of Thoracic and Cardiovascular Surgery). There is conflicting evidence regarding the long-term survival of patients aged 50-65 years with mechanical (M) or biological (B) aortic prostheses. General consensus of greater complications associated with the use of long-life anticoagulation in M and of reoperation in B. Similar survival with lower MACCE complications in bioprosthesis could reconsider their choice in patients aged 50-65 years, specially in the current TAVI era. The investigators are going to perform a multicentric retrospective observational study (Registry) about 15 year-outcomes Following Bioprosthetic vs Mechanical Isolated Aortic Valve Replacement for Aortic Stenosis in Patients Aged 50 to 65 Years in 5 Cardiovascular Surgery Centers in Andalousia (south Spain)
Study of Periodontal Tissues in Fixed Prostheses on Natural Teeth
Prosthetic Tissue DefectDental Prosthesis Complication2 moreWhen the tooth is severely compromised, it needs a prosthetic crown. The tooth is prepared to allow the housing of the prosthetic crown without difficulty. This study aims to compare two different types of preparations to see with which of the two the gingival tissue reacts best.
Customized Oral and Maxillofacial Reconstruction
Prosthesis FailureDental1 moreRegional oral and maxillofacial defects secondary to ablative tissue resection can contribute to severe aesthetic and functional loss, which influences patients' regular life and may cause psychological problems. Microvascular free flaps are considered the gold standard for reconstructing large oral and maxillofacial defects. In the past decade, with the help of computer-aided design (CAD)/ computer-aided manufacturing (CAM) customized implants and prosthesis (CIP) have led to a significant improvement of the operative accuracy, improve the flap survival rate and enhance the patients' quality of life. Concerning the increased overall survival rate of the patients, people pay more attention to the quality of life and aesthetic appearance which are influenced by the fitness and compatibility of the CIP. However, from literature reviews, the evaluation was various to be concluded in some certain conditions from pooled studies.
