Clinical Performance of All-ceramic Posterior Crowns. A Randomized, Prospective Clinical.

Dental Prosthesis Failure

This is a randomized, prospective clinical trial. The aim of the project is to assess the clinical performance of three types of tooth-supported crowns; monolithic high translucent colored zirconia, crowns of high-translucent colored zirconia with a mini-veneer buccally and crowns of lithium-disilicate glass-ceramic. Crowns will be placed on posterior teeth and evaluated from an esthetic and functional point of view, to identify if there are any differences between the materials.

A Phase III Study of Nimotuzumab Plus Concurrent Chemoradiotherapy in Loco-regional Esophageal Squamous...

Prosthesis Survival

Esophageal cancer is the sixth leading cause of cancer death in worldwide. Over the past 2 decades, well-designed clinical trials have documented the clinical benefits of combination of chemotherapy and radiation for localized esophageal cancer, either as primary therapy or in neoadjuvant setting. Paclitaxel, a radiation sensitizer, has important single-agent activity in esophageal cancer. Paclitaxel-based chemoradiation has been the framework for the recent Radiation Therapy Oncology Group (RTOG) trials of nonoperative management of esophageal cancer. Accumulating clinical evidence suggests that Epidermal Growth Factor Receptor (EGFR) represents a viable target in the treatment of esophageal cancer. EGFR expression is associated with poor prognosis. Nimotuzumab binds specifically to EGFR on both normal and tumor cells and competitively inhibits the binding of Epidermal Growth Factor (EGF) and other ligands, such as Transforming Growth Factor-α (TGF-α). Preclinical models have suggested synergy between nimotuzumab, paclitaxel, cisplatin and radiation. For our phase II study in locally advanced esophageal squamous cell carcinoma (ESCC), the combination of cetuximab and chemoradiotherapy has demonstrated both response and survival benefits. Myara et al reported that nimotuzumab plus concurrent chemoradiation therapy (CCRT) was safe and provided statistically significant objective response (47.8%) and disease control rate (60.9%) in nonresectable ESCC. With all these, the investigators plan to study phase III trial.

One-Tooth One-Time (1T1T) A Straightforward Approach to Replace Missing Teeth in the Posterior Region:...

Dental Implant FailedDental Prosthesis Failure

This study evaluates the success rate, as the biological and prosthesis complications, of posterior single-unit implants immediately loaded with a chair side Computer-Aided Design and Manufacturing (CAD-CAM) composite crown, after a follow-up period of 6 months,1,2,3,4 and 5 years. Complementary ex vivo analyses will be performed to evaluate the wear of restorations. The time and cost benefit of the presented digital workflow, as patient centered outcomes will also be evaluated.
