Guided Surgery for Implants with Dr. Izchak Barzilay

Dr. Barzilay discusses guided surgery with respect to implant surgery.  Highlights Implant surgery has always been guided. We used to guide surgeons as to where we wanted implants placed and they would try their best to place them in those exact positions or as close to them as possible. Nowadays, “guided surgery” has become more exact with the use of information from CBCTs and digital software systems. As a result, currently, CAD/CAM guided surgeries involve very precise implant placement not possible just a short time ago. Key messages CBCT radiography should be considered the gold standard now in implant dentistry ...

Peri-Implant Diseases with Dr. Mehdi Noroozi

Dr. Mehdi Noroozi comes back to speak to us about peri-implant diseases through the presentation of few cases. Highlights In this presentation, Dr. Noroozi talks about peri-implant disease which is often a result of improper diagnosis and treatment planning. It is important to educate our patients about the risk of peri-implant diseases. Currently, there are a significant number of implants that have inflammation or infection in practice. However, not all bone loss around implants is attributable to peri-implantitis. Bone loss could result from biologic width establishment, bone remodelling and early implant failure. Peri-implantitis is an inflammatory reaction around the tissues of ...

Digital versus conventional impressions for fixed prosthodontics: A systematic review and meta-analysis

This summary is based on the article published in The Journal of Prosthetic Dentistry: Digital versus conventional impressions for fixed prosthodontics: A systematic review and meta-analysis (August 2016) Context  In the fabrication of fixed multi- or single unit dental restorations, the accuracy of marginal and internal fit are integral to the long-term success of the crowns. Discrepancies in the internal fit can adversely affect the seating of the crown as well as the marginal fit. Typically, an impression captures the restorations’ margins and their internal aspects. Nowadays, impressions can be made using conventional impression materials such as polyether or polyvinyl siloxane or ...

Distinct Oral Neutrophil Subsets Define Health and Periodontal Disease States

Dr. Michael Glogauer, from the Faculty of Dentistry at the University of Toronto, recently published an article in the Journal of Dental Research titled: Distinct Oral Neutrophil Subsets Define Health and Periodontal Disease States. In this interview Dr. Glaogauer gives further details about this research and its significance for dentistry.  Highlights Neutrophils exit the vasculature and swarm to sites of inflammation and infection. However, these cells are abundant in the healthy, inflammation-free human oral environment, suggesting a unique immune surveillance role within the periodontium. We hypothesize that neutrophils in the healthy oral cavity occur in an intermediary parainflammatory state that allows them to interact ...

Boyce, DDS, FICD; Gary Klemons, DDS Context Nerve injuries in the maxillofacial region may happen as a result of trauma, neoplasms, infections, or secondary to a surgical procedure. Because of the limitations of such investigations there is a large range in the rates of injury reported from study to study.1 To complicate the issue further, the data are usually stratified, separating transient impairment from permanent loss of function, and only occasionally is the presence or absence of painful neuralgias ...
