Accelerated Osteogenic Orthodontic Tooth Movement: The Evidence

Accelerated Osteogenic Orthodontic Tooth Movement: The Evidence

May 6, 2018 3:25pm ‐ May 6, 2018 3:55pm

Surgically or periodontally assisted osteogenic orthodontics (SAOO or PAOO) involves bone perforations adjacent to the teeth to be moved. The purpose of perforations is to create trauma resulting in the regional acceleratory phenomenon (RAP) to produce an increase in the speed of tooth movement, shortening treatment times. There are numerous reported methods for inducing the RAP to affect the speed, amount and extent of tooth movement; however, many reports are anecdotal, or commercially promoted. This presentation will include the current evidence related to both invasive and minimally invasive techniques, as well as the use of bone grafting as an adjunct procedure.

Learning Objectives:

  • Discuss the evidence related to the various PAOO procedures reported to stimulate the RAP. 
  •  Discuss the efficacy of the various PAOO procedures and their limitations.
  • Determine those cases where PAOO may be beneficial.


Prevention of White Spot Lesion Development During Orthodontic Treatment

Prevention of White Spot Lesion Development During Orthodontic Treatment

May 6, 2018 3:45pm ‐ May 6, 2018 4:30pm

Orthodontic treatment success is jeopardized by the risk of development of white spot lesions (WSLs) around orthodontic brackets. Unfortunately, the formation of WSLs still remains a common complication during treatment in patients with poor oral hygiene. Nearly 75% of orthodontic patients are reported to develop enamel decalcification because of prolonged plaque retention around brackets. It is the orthodontist’s responsibility to minimize the risk of patients having enamel decalcifications as a consequence of fixed-appliance orthodontic treatment. This can be achieved by using fluoride-releasing, resin-modified glass ionomer cement (RMGIC) to bond brackets, with deproteinization of the enamel surface prior to phosphoric acid etching.

Learning Objectives:

  • Discuss the incidence of new WSLs at the completion of orthodontic treatment.
  • Explain why the enamel surfaces surrounding the bracket bases are protected from WSLs when brackets are bonded with RMGICs.
  • Detail why enamel deproteinization with Clorox (5.25% Sodium Hypochlorite), prior to etching, increases bracket SBS, diminishing bracket bond failure incidence, both with composite resin and with RMGIC (Justus et al, Seminars in Orthodontics, March 2010).

Thomas M. Graber Award of Special Merit Lecture: The Effect of Supplemental Vibration on Orthodontic Treatment with Aligners: A Randomized Trial

Thomas M. Graber Award of Special Merit Lecture: The Effect of Supplemental Vibration on Orthodontic Treatment with Aligners: A Randomized Trial

May 6, 2018 3:45pm ‐ May 6, 2018 4:05pm

Currently, one of the more popular methods to accelerate tooth movement is the application of vibrational forces to the dentition. The AcceleDent® device was introduced to the specialty of orthodontics to reduce treatment time. The purpose of this presentation is to answer these questions: Does the AcceleDent® device enables faster orthodontic treatment by allowing patients to change aligners every week, instead of every two weeks? Does the use of AcceleDent® result in better final alignment? Does the AcceleDent® reduce orthodontic pain and improve oral health related quality of life?

Learning Objectives:

  • Recognize the impact of supplemental vibration on ability to complete the aligner series when changed every week and the degree of alignment achieved.
  • Identify the impact of supplemental vibration on the orthodontic pain level the overall quality of life when used in conjunction with aligners.

Deciduous Teeth with Hypoplasia of the Permanent Successors and Autotransplantation of Premolars

May 6, 2018 3:55pm ‐ May 6, 2018 4:25pm

The presentation is based on materials of a long-term survival study of 132 deciduous molars with hypodontia of permanent successors of 87 patients and will describe and compare changes of deciduous molars with hypodontia of permanent successors in a long-term study and evaluate etiological theories of different development of successors.

Learning Objectives:

  • Select between different diagnosis of hypodontia of permanent successors: Agenesi: no treatment; Aplasia: close space, autotransplantation or implant). 
  • Observe that about 50% do not need any treatment (Agenesi).
  • Manage orthodontic treatment or rotation of transplanted teeth in due time.

Thomas M. Graber Award of Special Merit Lecture: Mesenchymal Stem Cell (MSC) Spheroid Constructs Containing Microfluidic BMP2-PLGA Microcapsules in Bone Tissue Engineering

Thomas M. Graber Award of Special Merit Lecture: Mesenchymal Stem Cell (MSC) Spheroid Constructs Containing Microfluidic BMP2-PLGA Microcapsules in Bone Tissue Engineering

May 6, 2018 4:10pm ‐ May 6, 2018 4:30pm

Recombinant human bone morphogenetic protein-2 (rhBMP-2) is a clinically available osteogenic growth factor. In its current form, approved for clinical use, however, the growth factor is delivered in excessively high doses, resulting in unpredictable bone growth and unwanted clinical side effects. In this study, we evaluated a novel system, slow-release hybrid delivery system for PLGA- rhBMP-2 microcapusles in combination with BM MSC spheroids, and assess if it can lead to improved BMP-derived bone formation.

Learning Objectives:

  • Recognize the challenges of growth factor delivery for bone tissue engineering.
  • Discuss the role of mesenchymal stem cells (MSCs) and recombinant human bone morphogenetic protein-2 (rhBMP-2) for future growth factor delivery systems.
  • Discuss the advantages and applications of culturing MSCs in 3D Spheroids.

Connecting the Past, Present and Future with Fundamentals that do not Change with Time

Connecting the Past, Present and Future with Fundamentals that do not Change with Time

May 7, 2018 8:00am ‐ May 7, 2018 8:45am

As time progresses in any scientific field, it is too often assumed that what is “new” is better than what is “old.” However, in orthodontics there are Laws of Equilibrium that will be trustworthy forever, as LAWS that govern orthodontic tooth movement do not change with time. Understanding and applying these LAWS in everyday orthodontics will clearly show that many so-called advances are nothing more than a failure to recognize that such “advances” were never required in the first place. This lecture will show that much of what has been taught mechanically is the cause of undesirable tooth movements while what we have been taught to avoid in many cases is the solution to avoiding such undesirable movements.

Learning Objectives:

  • Avoid the use of loops in orthodontic treatment. 
  • Essentially eliminate patient cooperation except for 1) Brush your teeth and 2) Keep your appointments. 
  • Discover that Round Wire has many advantages over Rectangular Wire and Partial Appliances have many advantages over Full Appliances.
