Impact of Antihypertensive Drugs on Implant Osseointegration

Dr. Faleh Tamimi, Assistant Professor in the Faculty of Dentistry at McGill University, spoke with Dr. Chiraz Guessaier about the research he conducted and the articles he co-authored on the impact of proton pump inhibitors on implant osseointegration. Highlights Propranolol enhances bone healing and implant osseointegration in rats’ tibiae Propranolol, a non-selective b-blocker widely used to treat cardiovascular conditions, favours bone accrual. Accordingly, we hypothesized that propranolol could be useful for improving bone healing and osseointegration. This in vivo study was designed to investigate the effect of propranolol on bone healing and osseointegration in rats’ tibiae. On 24 Sprague–Dawley rats, a unicortical defect was ...

A Paradigm Shift in Periodontal Disease

Drs. Ian Needleman and Adam Roberts spoke with Dr. Suham Alexander about a new paradigm shift in periodontal disease.  Highlights Periodontal disease is a progressive condition associated with bacteria. There has been little in terms of innovation with respect to periodontal disease. Traditional approaches have focused on eliminating bacteria; however, there may be alternative or adjunct treatments which can influence the ecology of the oral cavity. It is impossible to “sterilize” the oral cavity. This has led to new thinking about the use of probiotics as an adjunct to periodontal disease treatment. Various diseases are linked to dysbiosis in the ...

What is the Impact of Using Antimicrobials on the Development of Bacterial Resistance in Periodontal Disease?

Drs. Ian Needleman and Adam Roberts spoke with Dr. Suham Alexander about the impact of antimicrobials on bacterial resistance in periodontal disease.  Highlights Antimicrobial resistance is a newsworthy item in healthcare. This is a global dilemma as bacteria are able to proliferate in the presence of antibiotics which are meant to eliminate them. Overuse, misuse and inappropriate use in farming, agriculture and healthcare has led to this phenomenon. Every single use of antibiotics increases the selective pressure wherever they are to develop resistance which can happen in an instant. Resistant phenotypes can occur whether or not an antibiotic has been ...

New Implant Navigation System with Dr. Eszter Somogyi Ganss

Dr. Eszter Somogyi Ganss spoke about the new implant navigation system that she helped develop and test at the University of Toronto.  Highlights The new implant system aids in the safe and accurate placement of dental implant surgery. This tool involves a paradigm shift as one does not look at the patient but at the screen during implant placement surgery. Computer navigation is essentially a “GPS” system which allows the clinician to implement a virtual treatment plan in real time while visualizing the CBCT image as well as the position of the drill on the CBCT. This gives the dentist direction, ...

CDA Oasis Webinar: Managing Patients with Enamel Defects

On September 29th, Dr. John O’Keefe held a live webinar on managing patients with enamel defects. His guests were Drs. Nancy Vertel and Melanie Mattson.  Highlights Dr. Nancy Vertel, certified pediatric dentist and Dr. Melanie Mattson, certified orthodontist both from the Vancouver area speak to a live audience about enamel defects in children. Molar incisor hypomineralization issues are more common than practitioners may realize. Enamel defects are important to recognize and effectively manage as they can cause pain due to sensitivity in children. Factors predisposing children to MIH are unclear although different systemic conditions, environmental insults, prenatal and postnatal experiences ...

What Factors Should You Consider When Restoring Primary Teeth?

Dr. Reza Nouri, Certified Specialist in Pediatric Dentistry in the greater Vancouver area, gives the audience information on restoring primary molars. Highlights Understanding the anatomical differences between permanent and primary molars makes a difference in understanding how to restore the teeth including the type of preparation required as well as the behaviour of the restorative material that will be used to treat the teeth. Dr. Nouri also discusses the indications for unilateral and bilateral space maintainers as well as different types available for use.

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 ...
