Tooth impaction is a common but challenging problem in our clinical practice. However, it can be easily treated with temporary anchorage devices (TADs) and 3-D lever arms. In addition, TADs have been proven to be extremely reliable and effective in many other skeletal malocclusions, such as Class II correction with infrazygomatic crest (IZC) screws; camouflage treatment of severe Class III with buccal shelf (BS) screws and treatment of lower molar impaction with ramus screws.

This course begins with the basic skeletal anatomy of the bone structure that helps clinicians identify various screw insertion sites. Then participants will then be guided by Dr. Chang, in a step-by-step fashion, to learn how to place screws. The third part is to learn to perform the vertical incision subperiosteal tunnel access (VISTA) technique which, when combined with TADs and 3D lever-arm, can create access to the impacted tooth and later move it into the arch. Complete treatment of canine and molar impaction cases, from diagnoses to screw placement with or without surgical interventions will be thoroughly analyzed. Detailed and precise video demonstration on the world 1st impaction BoneModels® will be featured in this course.

Learning objectives

  • Properly diagnose and treat upper and lower impacted canines and molars.
  • Identify the insertion sites for IZC, BS and ramus screws in children and adults.
  • Describe the surgical procedures of the VISTA technique.
  • Create a 3-D lever arm and activate it together with the connected screw.

Why should I take this course?

Skill Development: Online courses with hands-on components provide an excellent opportunity to develop practical skills. Learning how to use TADs effectively in impaction treatment requires hands-on experience, and this course will allow participants to gain valuable proficiency in applying TADs in real clinical scenarios.

Enhanced Clinical Competence: TADs are an essential tool in orthodontic and oral surgery practices. By taking this course, participants can enhance their clinical competence, ensuring they are well-prepared to tackle complex impaction cases with confidence. This can lead to better patient outcomes and satisfaction.

Flexibility: Online courses offer flexibility in terms of when and where you can study. Participants can access course materials and practice sessions at their convenience, allowing them to balance their professional commitments and education effectively.

Expert Instruction: By having Dr. Chang as an instructor, participants will benefit from the knowledge, guidance, and insights, gaining access to the latest research, techniques, and best practices in TAD application for impaction treatment.

Networking Opportunities: Online courses often bring together participants from diverse geographical locations. This creates a unique networking opportunity where professionals can connect, share experiences, and learn from each other. Building a network of colleagues with similar interests can be valuable for future collaboration and support.
