CPD:  CPD  0:24   (closed)      Self assess

Feedback:  0 comments, 0 ratings


Abstract: Intrabony periodontal defects present a clinical challenge in the treatment of periodontal disease and maintenance of compromised teeth. The management of such defects ranges from non-surgical mechanical debridement to modern minimally invasive regenerative surgery. The incidence of intrabony defects is discussed along with prognosis and likely outcomes of various treatment options.

Clinical relevance: Vertical or intrabony (IB) defects are a common occurrence in patients suffering from advanced periodontal disease. Primary care practitioners must be aware of possible treatment options in order to make suitable referrals when initial phases of treatment prove unsuccessful.

During this webinar Eoin O’Sullivan will take you through his personal journey with digital scanning, explaining how he found himself in a dilemma when he had to replace his first iTero, after he had assumed that the scanner’s capabilities would transition to focus on orthodontics when it was bought out by Align Technology in March 2011. He will share his thoughts about which scanner would best suit his restorative practice, and why he opted for the next generation of iTero over all the other scanners on the market.
