Course Description:
This
lecture-prelinical laboratory course introduces first-year
dental students to the occlusion of permanent teeth. In the
didactic portion of the course, students will learn how maxillary
and mandibular teeth contact in normal and abnormal schemes,
and how the anatomy of the teeth, maxilla, and mandible interact
to dictate how teeth function together in health and disease.
In the preclinical lab, students will apply these principles
in waxing exercises that are designed to help them fully understand
occlusal concepts, refine motor skills developed in Resd 515,
and learn to candidly self-assess their work.
Educational Objectives:
The
broad objectives of this course are to:
1)
understand how teeth contact in maximum intercuspal position
and how this position differs from centric relation;
2)
understand and interpret how maxillary and mandibular teeth
move relative to one another and contact during excursive
movements of the mandible;
3)
understand how excursive movements are influenced by the morphology
of the teeth, mandibular condyles, muscles of mastication,
and temporomandibular joint anatomy;
4)
Describe and interpret the envelopes of mandibular motion
in the saggital, frontal, and occlusal planes and understand
why these envelopes have the shapes they have;
5)
Understand how articulators are used to approximate occlusal
function and the strengths and weaknesses of different types
of articulators in this regard;
6)
Develop sufficient motor skills to apply the principles of
occlusal function in constructing appropriately contoured
wax replicas of permanent teeth in appropriate occlusal function;
7)
Develop the ability to self critique and assess their work.
Course Outline:
Lecture
topics include: fabrication of master case models, articulator
use and function, contacts in centric occlusion, centric relation,
tempormandibular joint function, mandibular excursive movements,
mandibular envelopes of function, and how anatomical determinants
influence occlusal function in all anatomical planes.

Course Expectations:
Attendance
at all lectures and laboratory sessions is expected. The student
must accurately mount two sets of casts, then demonstrate
skill in waxing appropriately contoured teeth into correct
occlusal function in four separate graded waxing exercises
during normal course time. In addition, the student must pass
two waxing practical examinations by demonstrating independently
their waxing skill and ability to apply principles of occlusion.
The student must pass written midterm and practical examinations
and pass daily quizzes given in class. Finally, upon the completion
of the course, the student must visit the online course evaluation
site and complete the online evaluation or state online that
they do not choose to complete this evaluation. Throughout
all lectures and labs, professional and ethical behavior is
expected.
