Introduction
Occlusion is a broad subject, intimately interconnected with other disciplines of the degree in which students must gradually acquire a set of theoretical knowledge, practical skills and experience sufficient to make them effective. The main purpose of the course is to provide occlusion of the student sufficient knowledge to preserve the masticatory system. This is only achievable through a proper understanding of its various components and their function.
Pre-course requirements
Knowledge of the anatomy and physiology of the masticatory system.
Objectives
To expose and capacity students to carry out activities related to the diagnosis and treatment in occlusion.
Competences/Learning outcomes of the degree programme
- 33 - Knowing the morphology and function of the stomatognathic apparatus, including material on embriology, anatomy, histology and specific physiology

Evaluation systems and criteria
In person
1) - EVALUATION OF THEORY
- FINAL EXAMINATION
Multiple choice test of 50 questions with 4 answers, with only one correct answer. Each correct answer will add 0,2 points, the incorrect answers will subtract 0.066 points and the non-answer will not count.
It will be valued with a grade range from 0 to 10.
2) -EVALUATION OF CLINICAL PRACTICES:
The evaluation of the practices will be carried out continuously through different evaluations.
- PRE-PRACTICE TESTS
In each practical session (except for the 4 dedicated to review-recapitulation) an evaluation will be carried out by means of a test of 5 questions with 4 answers on the content of the explanatory video of the practice to be carried out and that have been done in previous seminars. Each correct answer will count 2 points, the incorrect answer will subtract 0.66 and the no answer will not count.
This evaluation will be face-to-face and will be carried out prior to the practice.
It will not be repeated, nor recoverable. Its non-performance will be counted as 0, in the event that there is no justification for force majeure.
-EVALUATIONS OF THE WORK PERFORMED
There will be 4 evaluations of the work done during the semester.
The assessment will consist of several items (variable according to assessment). The assessment will be made with a grade range from 0 to 10.
The FINAL NOTE will be according to the following percentages:
- Theoric exam ............................................... 45%
- Clinical practices .......................................... 55% (10% Pre-practice tests, 45% evaluations of the work done).
To pass the subject it is necessary to have passed the theory and the practices separately. Once passed individually, the percentages mentioned will apply.
