Lip support
Study Notes
- Tooth shade and incisal edge position are important factors in dental esthetics.
- Occlusal plane and Vertical Dimension of Occlusion (VDO) verification are crucial for dental function and patient comfort.
- Occlusal cant and gingival display should also be considered in dental esthetics.
- Lip support and contour play a role in the harmony of the lower third of the face.
- Phonetics, specifically the closest speaking space and the sibilant sounds (f, v, s, z, zh, j), are essential for evaluating the esthetic plane and OVD.
- Centric relation is a maxillomandibular relationship where the condyles articulate in the anterior-superior position against the posterior slopes of the articular eminences.
- Methods to record centric relation include anterior jig, leaf gauge, chin point guidance, bilateral manipulation, and muscle seated centric registration.
- Centric occlusion is the occlusion of opposing teeth when the mandible is in centric relation.
- Patient acceptance is a priority in dental treatment, especially for tooth shade and esthetics.
- A posterior palatal seal (PPS) area must be identified intraorally and transferred onto the master cast.
- The lab will score the marked PPS area on the cast by scraping a groove 1.5-2 mm wide and deep in a tapering manner.
