31 terms
Terms | Definitions |
|---|---|
 Primary function | prepare the food for swallowing and to facilitate digestion |
| Omnivorous dentition | joints muscles, proper alignment, dentition, muscles and alignment to chew both animal and vegetable type food |
| Static occlusion | the relationship of the jaws when they are brought together in centric occlusion |
| Centric occlusion | maximum amount of contact that the teeth have, how you normally bite down |
| Functional occlusion | occlusion seen when the teeth are brought together during chewing or mastication |
| Ideal occlusion | what we like to see ideally, when the upper teeth over lap the lower teeth slightly |
| Mal occlusion | when there are deviations from the 'ideal occlusion' |
| Occlusion | refers to the relationship of the teeth in the maxillary arch, when they are brought together in occlusion of the teeth with the mandibular arch |
| Prognathic | concave profile, prominent mandible, maxilla is normal size |
| Retrognathic | prominent maxilla, maxilla appears bigger in size, so that the lower arch is small, convex type profile |
| Mesognathic | straight profile, jaws are slightly protruded |
| Crossbite | maxillary and mandibular posterior teeth are either facial or lingual to their normal position |
| Unilateral crossbite | one side of the patients mouth |
| Bilateral crossbite | on both sides of the patients mouth |
| Open Bite | front teeth don't meet |
| Overjet | horizontal distance between the labial incisal surfaces of the mandibular incisors and the lingual incisor surfaces of the maxillary incisors |
| Underjet | aka cross bite. Horizontal distance between the labial incisal surfaces of the maxillary incisors and the lingual incisal surface of the mandibular incisors |
| Over bite | vertical distance which the maxillary incisors over lap the mandibular incisors |
| Normal Overbite | incisal edges of the maxillary teeth are within the incisal 3rd of the facial surfaces of the mandibular teeth |
| Moderate overbite | incisal edges of the maxillary teeth are within the middle 3rd of the mandibular teeth |
| Severe overbite | incisal edges of the maxillary teeth are within the cervical 3rd of the mandibular teeth |
| CLASS 1 occlusion: nuetroclusion: molar relation | The molar relationship: Mesial Buccal cusp of the maxillary first permanent molar occluse with the buccal groove of the first mandibular first permanent molar. (The mesial Buccal cusp of the maxillary first molar occluses with the Buccal groove of the mandibular first molar) |
| CLASS 1 occlusion canine relation: nuetroclusion | The canine relationship: The maxillary canine cusp falls distal to the mandibular canine |
| CLASS 2: distoclusion: molar relation | The molar relationship: the buccal groove of the mandibular first molar is distal to the mesial buccal cusp of the maxillary first permanent molar by at least the width of a premolar cusp. (the buccal groove on the mandibular first molar is distal to the mesial buccal cusp of the maxillary first molar) |
| CLASS 2: distoclusion The canine relationship | The maxillary canine cusp is anterior to the mandibular canine |
| Class 2 Division 1 | The mandibular is retruded(goes in), and one or more of the maxillary incisors are protruded (sticking up) |
| class 2 Division 2 | The mandible to retruded and one or maxillary incisors are retruded |
| CLASS 3: Mesioclusion: molar relation | The molar relationship: The buccal groove of the mandibular first molar is mesial to the mesial buccal cusp of the maxillary first permanent molar, by at least the width of a premolar |
| Class 3 canine relation | The canine relationship: the maxillary canine cusp is distal to the mandibular canine by the width of a premolar |
| Curve of Spee | curve that the teeth make that you see from a lateral aspect |
| Curve of Wilson | the curve that we see from behind the patient, inside the skull makes a W. |
