Despite the high success and survival rates associated with dental implants, early implant failure (before loading) can occur and represents the majority of reported failure. The aim of the present study was to identify the factors associated with early failure of dental implants in patients of Dubai Health Authority (DHA), Dubai, United Arab Emirates.

Although well established in the literature, confusion may still exist among dentists regarding the indications and functions of posts. Objective: This study aims to find out, if there is any difference in the selection of post system for endodontically treated teeth, between the dentists working in the private sector and the public sector in the United Arab Emirates. Methods: A questionnaire in the English language was sent randomly to dentists working (public and private sector), in Unites Arab Emirates (Dubai, Sharjah, Ras AL Khaimah, Fujairah) through email/hardcopies/survey portal. Results: Out of all reasons cited for the selection of posts, only the fewer number of visits (public sector) and cost (private sector) showed a statistical significance at p-value 0.023 and p < 0.01 respectively; Although fibre posts were generally the most commonly used posts by both secto...

This article presents a new approach that benefits from previous bone and soft tissue protocols. It combines new surgical and insertion techniques to perform immediate loading with delayed implant placement, avoiding the problems of discomfort, inconvenience, and anxiety associated with healing periods. It maintains a similar success rate to the present common technique. After osteotomy, bone healing passes through 3 stages (i.e., inflammation, fibrous tissue, and maturation). In the new approach, implant insertion is performed 2 weeks after drilling (i.e., during the fibrous phase). The insertion timing is so selected because collagen formation and revascularization represent an acceptable implant bed configuration. Flap surgery offers the optimal osteotomy approach, but esthetic outcomes are definitely compromised. Accordingly, adopting the punch technique alleviates several postoperative problems, such as pain, tenderness, and swelling. Moreover, the punch technique avoids the sutures needed to adjust the gingiva around the abutment. It provides both cosmetic and functional properties.

EC Dental Science 17.6 (2018): 961-967. Abstract A decision to extract or to keep a tooth was always a debatable matter in dentistry. Each dental specialty has its own perspective in that regards. Although, real life in the dental clinic showed that the decision is always multi-disciplinary, and that full awareness of all aspects should be there in order to reach to a reliable outcome. This article presents a simple evidence-based clinical chart for the judgment of restorability of teeth for better treatment planning.
