Study Notes
Occlusion
- Occlusion is influenced by eruption patterns, facial development, and mesial drift.
- Muscle forces affecting teeth alignment include tongue pressure pushing teeth out, and cheeks and lips holding teeth in place.
- Curve of Spee is a slight curve in normal occlusions, higher at anterior and posterior teeth, dipping in the middle.
- A flat-plane occlusion does not have the same space for tooth eruption as a curve of Spee occlusion.
- Open bite occurs when anterior teeth do not touch in centric occlusion.
- Overbite is the extension of the maxillary anterior incisors below the mandibular ones; average in children is 2.5 mm.
- Overjet is the facial horizontal overlap of the maxillary teeth over the mandibular teeth; average in children is 3 mm.
- Class 2 canine relationship is characterized by the mandibular canine's distal position being distal to the maxillary canine by one premolar width.
- Mesial step describes a common primary occlusion relationship where the distal surface of the mandibular second primary molar is more mesial than the maxillary one.
- Factors impacting occlusion include hereditary, unrestored baby teeth, decayed molars, impacted teeth, missing teeth, growth of condyles, and leeway and primate spaces.
- Ideal occlusion involves a flat occlusal plane with a slight curve of Spee, tight proximal contacts, symmetrical upper and lower arches with no rotated teeth, correctly tipped teeth, and appropriate incisor and molar relationships.
- Factors affecting occlusal relationships include the relationship of the primary molars, early mandible growth, and relationship between the permanent molars.
- Tooth movement in the alveolar bone can occur, causing protrusion.
Primary Occlusion
- The vertical height of primary occlusion is established by primary molars.
- Intercuspation refers to how the maxillary teeth touch, contact, and interlock with the mandibular teeth.
- Flush terminal plane is more common in children than distal step.
- Mesial step describes an occlusion where the distal surface of the mandibular primary second molar is mesial to the maxillary one.
- A distal step occurs when the second mandibular molar is distal to the second maxillary molar.
- Primary spaces are diastemas and primate spaces that can occur when the arches grow but the teeth don't.
- Leeway space is the difference in size between primary molars and premolars.
- Deep bite occurs when posterior teeth do not erupt far enough while the mandible grows, resulting in a smaller occlusal plane.
- Thumb sucking and tongue thrusting can affect permanent incisor positioning
Occlusion Development
- Occlusion development begins with primary teeth eruption, first with central incisors and continuing with lateral incisors, and then molars.
- At 16 months, primary molars erupt, establishing the vertical height of primary occlusion.
- By 2.5 years of age, primary dentition is complete.
- Tongue and lip pressure affect facial tooth movement.
- Intercuspation is crucial for proper teeth positioning and chewing function.
Additional Notes
- Skeletal Class 1 is considered normal; Class 2 is retrognathic and Class 3 is prognathic.
- Canines and first molars assist in classifying occlusion.
- Common classifications of occlusion include Class 1, Class 2, and Class 3.
- Lateral excursion involves the jaw moving to the side.
- Group function occurs when premolars meet; canine rise happens when only canines meet.
- Premature contact occurs when a tooth touches beforehand, disrupting rest of the occlusal sequence.
- Protrusion occurs when teeth are pushed anterior.
- Occlusion is affected by factors like disease or acromegaly.
- Classification can relate to jaw structure (skeletal classfication) in addition to teeth relationships
