Morning speaker for Doctors

Root resorption, Class II correctors, and lingual orthodontics – updates for the clinician with Glenn T. Sameshima, DDS, PhD

Orthodontic root resorption – an update for the clinician.  The most commonly asked questions about this topic will be addressed based on current evidence and thirty years of clinical experience.  Who are the patients most at risk and how to manage them? Are there any new ways to detect root resorption early? How does the clinician manage root resorption at progress? Or at the end of treatment?  What is the long term morbidity of a short rooted tooth – should they be replace by implants before they fall out? These and other frequently asked questions about the subject will be presented in an evidence based and clinical relevant manner.

Class II correctors – do they work?  The newest flavor of corrector and growing quickly in popularity is the Carriere distalizer.  The focus of this presentation will be the findings of a study recently published in Progress in Orthodontics by a team at the University of Southern California.  The results will be compared and contrasted with another study that came out a few months after. A clinician’s viewpoint on the pros and cons will also be presented to balance the presentation.

Lingual orthodontics – it’s baaaaack!  Harry Dougherty Sr was fond of saying that if you stick around long enough in our profession, things that you get excited about then lose interest eventually make their way back again.  Lingual is the comeback kid of the ‘10s. At USC a group of ortho faculty and residents working with the materials engineers developed and brought to market a novel lingual appliance they call inBrace.  We have been using the system in the clinic at USC and an overview of how it is different from other past lingual systems will be presented with a selection of clinical cases.    

Learning objectives:

  • What patients are at greater risk for severe root resorption?
  • Is there less root resorption with certain appliances?
  • Does a tooth with severe resorption have to be extracted?
  • What do I do if I find severe resorption at progress?
  • How do interarch correctors work?
  • Are the corrections dental, skeletal, both or neither?
  • How is inBrace different from other lingual appliances?


Morning speaker for Team Members

Orthodontic Excellence: Developing a Patient Centered Practice with Andrea Cook

Simplify systems to focus on quality patient care.  This statement has become the goal for many orthodontic practices.  This is a good time for practices to look internally at their protocols, procedures and systems.  Developing smooth running, efficient, patient-based systems will allow the practice to grow.

What’s new in sterilization and instrument reprocessing for today’s orthodontic offices.

Today’s orthodontic teams are challenged with having the time, knowledge and equipment to process instruments and achieve compliance with the CDC and WAC guidelines and sterilization protocols.   We will review the current Guidelines for Infection Control in Dental Health-Care Settings, 2003 and Washington Administrative Code (WAC) as well as the recent update to these guidelines.   We will discuss tips and tricks to help make instrument reprocessing safe, fun, and effective for the orthodontic team!

Session Objectives - As a result of attending this session, you will be able to:

  • Understand the most recent updates for CDC and Washington State infection control recommendations
  • Describe the challenges bloodborne and respiratory infections present to dental healthcare workers
  • Describe recent technology advances and protocols for instrument processing and sterilization
  • Understand how to effectively monitor reprocessing and sterilization procedures
  • Describe the use of disposables and disinfectants used in environmental surface asepsis

It’s All about Timing – How to Keep Your Clinic on Time

Keeping your clinic running on schedule is an important factor in today’s' successful orthodontic practice.  A well-built schedule will allow clinician adequate time for each patient and procedure to ensure the highest quality patient care is being delivered.   Learn how the entire team can handle late and early patients, breakage, and life's challenges in the fast-paced office.

Session Objectives:  As a result of attending this session, Teams will be able to:

  • Develop schedule options and efficient templates
  • Understand clinical reports to evaluate clinical flow
  • Learn how to deal with late/early patients


Afternoon speaker for Doctors

Possibilities and Challenges with Skeletal Expansion with Tung Nguyen, DMD, MS

Deficiencies in transverse dimension for non-growing patients are usually managed with either orthognathic surgery (LeFort segmental osteotomy) or Surgically Assisted Rapid Palatal Expansion (SARPE). The recent introduction of Miniscrews Assisted Rapid Palatal Expansion (MARPE) offers a non-surgical alternative for the correction of posterior crossbites in non-growing patients. The technique has gain popularity because it is relatively easy to implement and been shown to produce orthopaedic changes. However, what does the research show in regards to the effectiveness of MARPE and what are the potential risks to our patients? This lecture will review the MARPE protocol, discuss clinical studies, and compare short-term data on MARPE and SARPE.

As a result of attending this lecture, you will be able to:

  • Obtain orthopedic expansion in non-growing patients using MARPE.
  • Compare 3D results for miniscrew assisted expansion versus surgically assisted expansion.
  • Review clinical MARPE protocol and discuss pitfalls.
  • Review different miniscrews expansion devices currently on the market


Afternoon speakers for Any Team Members

Customer Service Vs. Customer EXPERIENCE with Andrea Cook

What is the difference between these two scenarios we are all too familiar with?  Customer service is the bare bones transaction between a patient and an office.  Customer experience is when team members are there because they want to be and because they realize the importance of their position in the office.

We will discuss the differences and how each team member can make every interaction with your patients a true customer experience.  These experiences will build your reputation and a team of all stars that can deliver one at every opportunity.

As a result of attending this lecture, attendees will be able to:

  • Determine how great customer service can build your practice
  • Understand the difference between customer service and customer experience
  • Develop tools to train team members to deliver your customer experience


Afternoon speaker for Clinical Team Members
Debond!  How to safely remove brackets, bands, and bonding resin from tooth surfaces with Geoff Greenlee, DDS, MSD, MPH

This session is designed to provide the necessary background information to prepare orthodontic dental assistants to:

  • Safely remove fixed orthodontic appliances
  • Understand the evidence about patient comfort and enamel safety during bracket removal
  • Safely remove bonding composite resin and polish enamel
  • Understand and use a dental handpiece and rotary instruments
  • Recognize risks and pitfalls during appliance removal

Part of this session will be dedicated to hands-on training in safe appliance debonding and composite resin removal with a dental handpiece. Attendees will gain knowledge and skills preparing them to progress on to supervised training on patients with a licensed orthodontist at their office.

The hands-on section of this class is currently limited to 50 particpants.  A $10 registration fee is required.
