Study Notes
- Smile can be classified into two types: posed and spontaneous
- Posed smile is static, sustained, and fairly reproducible, while spontaneous smile is involuntary and represents enjoyment or maximal contraction
- Duchenne smile, also known as a genuine or true smile, involves the contraction of both zygomaticus major and orbicularis oculi muscles
- Researchers have used active appearance models to differentiate Duchenne smiles from non-Duchenne smiles for biometric applications
- Eight components of a balanced smile include vertical dimension, incisor display at rest and during speech and smile, philtrum and intercommissural distances, smile arc, incisor show on smile versus rest versus speaking, and upper lip curvature and length
- Interactions of hard tissues, soft tissues, and growth over time can impact orthodontic diagnosis and treatment planning
- Ideal smile should expose minimal gingiva (unless young or female), have symmetric and harmonious gingival contour, and have anterior and posterior segments in harmony with the smile arc
- Gummy smile can be classified into degrees based on the amount of gingival display, and treatment options can vary from orthodontics to orthognathic surgery
- Measurements for accurate decision making in orthodontics include clinical and anatomic crown length, width of keratinized tissue, and radiographic location of the cemento-enamel junction
- Incisor crown height increases dramatically during adolescence and tapers off in later years, and interactions of hard tissues, soft tissues, and growth over time can impact orthodontic diagnosis and treatment planning
- Short tooth syndrome can result in altered passive eruption, which can affect the smile and require treatment management.
