UDLT 102 - Dental Morphology, Occlusion & Articulation


Students will develop an overarching knowledge of human dental morphology to include anatomical landmarks, terminology, tooth numbering systems and tooth development, introduction to human mandibular movement through the examination of the interrelation of skeletal and muscular systems, tooth surfaces and the temporomandibular joints. Also includes types of cusps with their interrelation to the opposing dentition, examination of the centric relation and vertical dimension in edentulous patients, types of dental articulator and comparisons of normal occlusion and various malocclusions i.e. Angle’s Classification.

  2. Identify and explain basic terminology.
  3. Locate, identify, and describe basic anatomical landmarks of the teeth, permanent dentition, and deciduous (primary) dentition.
  4. Detail the location and function of head and neck skeletal structures and musculature.
  5. Enumerate oral structures and related physiology.
  6. Sculpt teeth #3-8 maxillary and #19-22 mandibular in soap, wax, or gypsum.
  7. Describe dental anatomy and morphology as it relates to occlusion and mastication.
  8. Describe elements Angle’s Classification of occlusion
