Loma Linda Transverse lecture April 2016


Presenter:  Dr. Grummons                       Lecture Date: Monday, April 25, 2016

Lecture Topic/Title:  Transverse Analysis and Expansion Appliances Therapies

Utilizing frontal facial information, therapeutic approaches are more specific and effective, while directed toward particular etiology.  Occlusal plane, midline, chin location, and smile esthetics are primarily addressed.  Beautiful facial proportions and smile harmony can be developed despite initial facial dysmorphosis and disproportions.  Asymmetry of the facial parts is the rule, rather than the exception.

Patients view themselves from the frontal perspective, so this carries priority in assessing problems and treatment outcomes.  It is important to know the etiology of asymmetry to assist others with genetic counseling.  In orthodontics, we are essentially a generation of profiles, looking at the lateral cephalometric image.  Facial harmony and smile beauty are optimal when facial and dental midlines are aligned.  The occlusal plane should be level, or nearly so.  The chin should be centered, or nearly so.  The maxillary width should be sufficiently wide to be in harmony with the individual patient facial type and morphology.  Best facial development and proportionality exist when the transverse skeletal and dental components are optimized transversely and are symmetric.

Lecture Goal(s):

Many clinicians have not employed the frontal perspective.  Therefore, the purposes of this lecture are to: (1) update the findings in the morphology and growth in the transverse dimension; (2) simplify evaluation of facial asymmetry using the Ricketts and Grummons frontal analyses; (3) describe practical clinical applications of anteroposterior images and analysis; and (4) demonstrate the needs and benefits of three-dimensional diagnostic and treatment applications.
