Speaker: Sal Ruggiero, DMD, MD

Osteonecrosis of the jaw associated with antiresorptive medications and certain targeted cancer therapies has received a considerable amount of attention in the scientific and lay community since it was first described over 15 years ago. Since that time there has there been significant progress toward understanding the pathogenesis of (MRONJ) and the multiple variables associated with its clinical presentation. This lecture will provide a review of the evolving theories on pathogenesis and also provide an update of the recent clinical aspects related to defining, treating and preventing MRONJ.


Course Objectives:

  • Review of the clinical signs and symptoms of MRONJ

  • Review of the risk factors and prevention strategies related to MRONJ

  • Review of pathophysiology and treatment strategies

“Achieving Optimal Implant Esthetics Using a Team Approach”

Speaker: Ana Becil Giglio, DDS & Graziano Giglio, DDS

The presentation will focus on optimizing the esthetic results of dental implant therapy by using a collaborative approach between the surgeon, the restorative dentist, and the laboratory technician. The three principal factors to consider in implant therapy are:

1. Surgical parameters which include hard and soft tissue requirements, three-dimensional implant
position, and implant size.

2. Restorative parameters comprised of screw access angle, abutment dis/re-connection, restorative contours, restorative materials, screw vs cement retention, and occlusion.

3. Implant collar features including the collar surface and abutment-implant connection.


Treatment options, planning, and sequencing of care to reduce the number of visits, will be presented in detail. The surgical and restorative therapies will range from single implant solutions to complete arch rehabilitations. Topics that will be discussed: immediate implant placement and provisionalization; peri-implant complex considerations; esthetic restorative implant components; and the use of digital
technology in implant therapy.

Course Objectives:


At the end of the lecture the participant will be able to:

  • Evaluate the patient’s esthetic and functional needs

  • Formulate a suitable treatment plan, sequence, and coordinate treatment effectively

  • Understand the peri-implant process as it relates to implant health and esthetics

  • Improve patient comfort and care by using digital technology in an interdisciplinary approach

"Dentistry’s New Role in the Future of Optimizing Healthspan"

Speaker: William Hang, DMD

In 2017 the ADA mandated that dentists screen all patients for airway problems. But what is screening without the knowledge to address problems that are found? What does that mean for restorative dentists? What does that mean for orthodontists?

This presentation will identify how the orthodontist and restorative dentist can collaborate in treatments which optimize facial balance and airway for patients from age 3 to 103.

Course Objectives:

After the presentation all will know:

  • Why the goal of ALL orthodontic treatment should be optimizing facial balance and airway

  • Why orthodontic treatment in the primary dentition should become the standard of care

  • That restorative dentistry is often not only desirable but necessary in reversing previous orthodontic retraction and alleviating pain patterns


About the Speaker:
Dr William Hang graduated from the University of Illinois College of Dentistry and the University of Minnesota Orthodontic program where he briefly taught orthodontics. He was in practice for 47 years. Having been traditionally trained, he extracted teeth for crowding and often retracted the teeth. For the last 40 years, however, he has been a pioneer in non-retractive treatments to improve the airway in patients of all ages. He received a Lifetime Achievement Award from the American Academy of Physiological Medicine and Dentistry for his work.

Dr Hang recently founded OrthO2Health™ to teach and mentor doctors about airway healthy orthodontic treatments for all ages. His Early Childhood Health-Centered Orthodontic Mentorship™ (E.C.H.O.) focuses on treatments for children approximately age 10 and under with an emphasis on treating in the primary dentition. The Hang E.R.R.S.™ (Extraction Retraction Regret Syndrome™) Orthodontic Mentorship addresses treatments for teens and adults to optimize facial balance and airway. Reversing previous orthodontic traction including re-opening previous bicuspid extraction spaces or missing lateral incisor spaces and surgery are also integral parts of this mentorship.




“Full Arch Digital Workflows"

Speaker: Justin J. McElroy, BS

The presentation will review what’s current in digital design and treatment planning. The lecture will demonstrate the streamlined workflow using digital planning and diagnostic records for full arch implant restorations. Mr. McElroy will share his experiences using  photogrammetry and intraoral scanners in the full arch modeless workflow.

“XTX Talk: An Interactive Session”

with Richard B. Smith, DDS, Moderator

With the evolution of the NGS AMD to a true multidisciplinary organization, a new perk of memberhsip is access to XTX, or Cross-Treatment Talks. XTX Talks are treatment planning style seminars conducted several times per year in a virtual format and are intended to reflect the current trend of cross-discipline education and team dentistry. Patient treatments are presented and attending members from various specialties are invited to collaborate on how they would treatment plan and execute the cases

The program will be devoted to giving members and guests a look into a live XTX-style treatment planning seminar. In addition to hearing the speaker give his scheduled preesntation, everyone can participate with the speaker as he presents and reviews patient treatment. With Dr. Richard Smith, we’ll get insight into how this highly skilled and knowledgeable dentist approaches a comples, mutiisciplinary treatment with his own specialist perspective. After the case has been discussed by him we will open up the floor to questions.

Audience participation will be encouraged. The objective of the presentation is the same as that of the NGS AMD a a whole: high-quality educational content in a supportive and collaborative environment.
