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.

Knowledge of the anatomy and physiology of the masticatory system.

To expose and capacity students to carry out activities related to the diagnosis and treatment  in occlusion.

• 33 - Knowing the morphology and function of the stomatognathic apparatus, including material on embriology, anatomy, histology and specific physiology
• 65 - Diagnosing, planning and undertaking, at a general level, multidisciplinary, sequential and integrated treatment of limited complexity for patients of all ages and conditions and patients with special needs (diabetes, hypertension, oncological diseases, transplants, immune-depression, anti-clotting, etc.) or disabilities. Specifically the dentist should be competent in establishing a diagnosis, a prognosis and developing a suitable treatment plan, particularly in terms of orofacial pain, temporo-mandibular disorders, bruxism and other parafunctions; dental and periapical pathology; oral and dental trauma; periodontal and peri-implanted tissue pathologies; pathology of the mandibular bone, of soft oral tissue and annex glands; states of partial or total edentation and planning rehabilitation treatment via dento-muco supported prostheses, or dental impants, dental malpositions or malocculusions and other anatomical or functional alterations of the face or the stomatognathic system and their potential orthodontic, orthopaedic or surgical corrections
• 67 - Creating diagnostic models, setting them up and taking inter-occlusal registrations
• 70 - Evaluating motor and sensory oral, mandibular and annex function
• 88 - To undertake non-surgical treatment for temporo-mandibular disorders and oro-facial pain
• 90 - To identify and correct oral habits that are susceptible to causing or exacerbating malocclusions
