Dentistry Today, a Multi-Disciplinary Approach

Saturday, September 16th – 18 Minute Presentations

8:30 am – 8:50 am – Dr. Peter Walford, Hornby Island, BC

Title: Failed or impossible implants? A sound and attractive cast metal solution from the adhesive world.

Synopsis: Root proximity, inadequate bone, insufficient length, integrative failure or restricted budgets are common reasons for implant contraindication which can leave us stumped for fixed options. This presentation shows an innovative adhesive retainer design that enables an esthetic prosthesis, on single or multiple abutments, with 400 cases over 12 years to establish effectiveness.


  1. Typical indications, applications and esthetic outcomes
  2. Elements of the retainer design that insure success
  3. Method of preparation to ensure conservative predictability
  4. Importance of an opaque and hydrophobic cement to longevity and esthetics

Bio:  BC Dentist Dr. Peter Walford McGill 1975, FCARDP, mentors study groups, publishes in Oral Health Journal, presents nationally at dental meetings, was the first online mentor for BCDA, and frequently demonstrates at PDC Live Stage.    He counts Raymond Bertolotti and Richard V. Tucker as his biggest influences, combining innovation with reliability. He runs an organic farm on a BC Gulf Island, is a grandfather, triathlete, and builds high-performance boats for salt water as recreation.

8:50 am – 9:10 am – Dr. Dimitrios Karastathis, Vancouver, BC

Title: Everything you wanted to know about Peri-implantitis

Synopsis: As the number of implants being placed in patients has grown exponentially over the years, so too has the number of implant complications.  One of the most severe complications that affect the long-term prognosis of an implant is peri-implantitis.  This lecture will cover many aspects of this condition including diagnosis, etiology, anatomy of the disease, prevalence, management and prevention.  By the end of the presentation, the audience will have a clear understanding of this disease and be prepared to inform their patients with relevant and up to date information.


  1. Understand the causes of peri-implantitis
  2. Understand how to monitor and diagnose peri-implantitis
  3. Understand treatment options for peri-implantitis

9:10 am – 9:30 am – Dr. Ron Zokol, Vancouver, BC

Title: Introduction into Dynamic Surgical Navigation

Synopsis: Dynamic surgical navigation is now the leading edge of accuracy in providing implant surgery.  While introduced approximately 14 years ago by Robodent in Germany, other companies seeing the marketing benefits of this technology have entered into the field.  The Inliant Clinical Navigation System revolutionary marker and tracker design provides comfort, convenience and accuracy for implant placement surgery.  This presentation will demonstrate the clinical procedures in using the Inliant product and the quality of the end result.


  1. To provide an understanding of the concept of Dynamic Surgical Navigation
  2. To demonstrate the criteria required to perform these procedures
  3. To effectively show how Dynamic Surgical Navigation is used in surgery

9:30 am – 9:50 am – Dr. Ira Sy, Richmond, BC

Title: Guided Tissue Profiling in the Esthetic Zone Around Natural Teeth and Endosseous Implant

 Synopsis:  The management of the soft tissue aesthetic zone with oral implants and natural teeth have shown to be challenging. Often times, the end result can be affected by the choice of the treatment planning, sequence, and surgical technique. As implant replacement continues to be a viable option in the esthetic zone, more emphasis has been placed on the result of the soft tissue interface with the endosseous implant and the prosthetic suprastructure. This program will illustrate some of the current trends in implementing soft and hard tissue augmentation in the esthetic zone in conjunction with immediate implantation and natural provisionalization.

Additionally, an interdisciplinary approach will be presented in the management of the esthetic zone encompassing various treatment strategies with provisionalization techniques and minimal invasive surgical techniques will be shown.


  1. Be able to understand the comprehensive treatment planning process with soft tissue profiling to enhance the aesthetic result.
  2. To understand the importance of utilizing minimally invasive approaches to enhance and maintain the soft tissue result.
  3. To have a three dimensional and biological approach in planning implant treatment in the aesthetic zone.
  4. Be able to create a blue print and plan in order to envision the aesthetic and functional result prior to initiating treatment.

9:50 am – 10:10 am – Dr. David MacDonald, Vancouver, BC

Title: Cone-beam computed tomography and the restorative dentist

Synopsis: Cone-beam computed tomography (CBCT) assists the prosthodontist not only to place the implant in sites which allow optimum restoration, but also minimize complications, such as permanent nerve injury, excessive bleeding in the floor of the mouth and mandibular fracture. CBCT also assists in the identification of those teeth which are likely to be successfully treated or retreated by the endodontist. Since modern prosthodontics is applicable to patients of all ages, the prosthodontist needs to be aware of the most frequent and important lesions that may present. CBCT is shown itself to be a valuable diagnostic tool for such lesions.


  1. Identify and describe of the components of CBCT and understand their importance.
  2. Determine when CBCT should be prescribed for the restorative patient.
  3. Understand the range of pathology that may present on a CBCT dataset of a restorative patient
  4. Determine when a CBCT dataset should be referred.
