Rolf G. Behrents, DDS, MS, PhD
Orthodontic Program Director

The Center for Advanced Dental Education at Saint Louis University offers a thirty month program in the specialty of Orthodontics that leads to a Master of Science in Dentistry. The program offers three basic areas of training: an extensive and comprehensive clinical experience that involves diagnosis, treatment planning, active treatment, and retention of patients representing a variety of malocclusions and craniofacial deformities; a didactic core and specialty education that encompasses biomedical sciences as well as clinical concepts; and research related to the discipline.

The program is fully accredited by the Commission on Dental Accreditation of the American Dental Association. Following completion of the program, graduates are educationally qualified for certification by the American Board of Orthodontics. Find out more information about applying to this program.

Lectures and demonstrations with a laboratory component that includes cephalometric tracing technique, visualization of treatment objectives for orthodontic and surgical orthodontic cases, analysis of growth pattern, and treatment results. (Offered every year.)

ORTH.5310 Oral Biology (1)
Attention is focused on the relationship between the observed clinical events in tooth movement and the nature of the associated physiological events. Emphasis is placed on those responses that may occur on the tissue, cell and macromolecular levels of organization. In particular, the physiology of mineralized connective tissue and the process of tooth eruption are used as models to explore the biology of orthodontic tooth movement. (Offered every year.)

ORTH.5350 Surgical Orthodontics (1)
Acquaints the graduate student with those surgical procedures that directly relate to orthodontic treatment plans. The lecture series encompasses a review of diagnostic procedures, surgical techniques for the treatment of maxillary and/or mandibular skeletal excess and deficiency as well as laterognathism, Class II malocclusion and adjunctive techniques of genioplasty for correction of microgenia and macrogenia. In addition to surgical consideration of jaw deformities, time is allocated for miscellaneous pathological conditions. (Offered every year.)

ORTH.5370 Orthodontic Problems Related to Cleft-Palate Patient (1)
A study of the various aspects of the congenital cleft-lip-and-palate condition with a consideration of the several professional areas concerned with the total habilitation of the cleft-lip-and-palate patient. Coursework includes diagnosis and treatment of patients at the Cardinal Glennon Hospital Cleft Palate Center. (Offered every year.)

ORTH.5390 Speech Problems Related to the Oral Mechanism (1)
Basic anatomy and physiology of the speech mechanism. Introduction to phonetics and speech sound production. Survey of communication disorders; significance of the disorder for the orthodontist, and orthodontic treatment plan. (Offered every Fall semester.)

ORTH.5400 History of Orthodontics (1)
Evaluating concepts in pre-specialization disciplinary organization, ethical considerations, and humanist aspects of the profession. (Offered every year.)

ORTH.5500 Diagnosis and Treatment Planning I (1)
Evaluation and treatment planning of various types of malocclusion. (Offered every year.)

ORTH.5530 Clinical Diagnosis I (1)
The clinical application of the various diagnostic procedures and philosophies of orthodontic diagnosis and a presentation of practical procedures to help in the management of unusual problems that can arise during the course of treatment. (Offered every year.)

ORTH.5540 Clinical Diagnosis II (1)
Continuation of Clinical Diagnosis I. (Offered every year.)

ORTH.5550 Orthodontic Analysis and Treatment Modalities (1)
An in-depth presentation of specific and complex problems that can and do arise in orthodontic practice. Recognition, precautions, and various treatment modalities for each problem are discussed. Advances in orthodontic technology will be presented utilizing diagrams, photographs, clinical aids, and actual demonstrations to further enhance knowledge in dealing with difficult situations. (Offered every year.)

ORTH.5560 Clinical Case Conference (0-1)
In seminar format, each class meeting features the presentation by one of the students of the work-up and diagnosis of an active orthodontic patient. The other students and faculty propose and critically evaluate possible treatment plans and modalities. The presenting student then reviews the actual treatment plan being followed and the progress in therapy to date. (Offered every year.)

ORTH.5580 Clinical Specialty Seminars (1)
Individual clinical faculty members present their personal philosophies of diagnosis, treatment planning, active therapy, and retention. These sessions serve also to introduce the students to a diversity of techniques and appliances and therapy for unusual and exceptional categories of patients and cases perhaps not routinely seen in the mainstream of orthodontic care. (Offered every year.)

ORTH.5600 Introduction to Clinical Orthodontics (2)
A didactic and laboratory introduction to basic clinical principles and techniques. Initially, instruction covers the policies and procedures of the orthodontic clinic and later, the development of a patient diagnostic data base including study casts, photographs, cephalograms, and clinical evaluation of the patient. (Offered every year.)

ORTH.5610 Introduction to Clinical Orthodontics II (1)
A continuation of ORTH.560. A concentrated, didactic course that addresses in some depth the procedures of diagnosis, treatment planning, and application of clinical therapy toward the solutions of orthodontic problems in patients of various and dental development. (Offered every year.)
