🗑

🗑
|
||||

🗑
|
||||

🗑
|
||||
| Pt can't have different occlusion on opposite sides of the mouth | False. Pt can have different occlusions on opposite sides of the mouth;
🗑
|
||||
| Types of Crossbites | Anterior and Posterior
🗑
|
||||
| Anterior Crossbite | Maxillary Incisors are lingual to mandibular incisors
🗑
|
||||
| Posterior Crossbite | Maxillary or mandibular posterior teeth that are lingual or facial to their normal position
🗑
|
||||
| Malrelations of teeth: edge to edge | Incisal surfaces of maxillary anterior teeth occlude with the incisal surfaces of the mandibular anterior teeth, instead of overlapping
🗑
|
||||
| Malrelations of teeth: end to end | Molars and premolars occlude cusp to cusp;
🗑
|
||||
| Open Bite | Lack of occlusal or incisal contact between maxillary and mandibular teeth
🗑
|
||||
| Overjet | Mandibular anterior teeth are lingual to the maxillary anterior teeth; Horizontal measurement between maxillary and mandibular teeth;
🗑
|
||||
| Underjet | Maxillary anterior teeth are lingual to the mandibular anterior teeth; Horizontal measurement between maxillary and mandibular teeth
🗑
|
||||
| Overbite can be: | Normal, Moderate, Severe
🗑
|
||||
| Normal overbite | incisal edge of maxillary incisors within the incisal third of the mandibular incisors
🗑
|
||||
| Moderate overbite | incisal edge of maxillary incisors within the middle third of the mandibular incisors
🗑
|
||||
| Severe overbite | incisal edge of maxillary incisors within the cervical third of the mandibular incisors;
