What is a protrusive Interocclusal record?
a record of the positional relationship of the teeth or jaws to each other, recorded by placing a plastic material that hardens (such as plaster of Paris or wax) between the occlusal surfaces of the rims or teeth; the hardened material serves as the record; it may be registered in centric or eccentric positions, as …
What is an Interocclusal record?
Interocclusal records are the maxilla mandibular records that are used to transfer interarch relationships from the mouth to an articulator. An accurate interocclusal record minimizes the need for intraoral adjustments during prosthesis insertion.
How do you record a protrusive bite?
Once the wax is warmed, take it to the patient’s mouth and cover the edge of the upper incisor teeth. Instruct your patient to push their mandible forward, hold it forward, and bite down. The patient’s lower teeth are now ahead of their upper teeth – otherwise known as a protrusive position.
What is the purpose of a protrusive record?
Purpose of the protrusive record The protrusive record allows a clinician to extrapolate all mandibular movements: maximum intercuspal position (MIP), protrusive end to end, lateral excursive, and the pathways to them.
What is the purpose of making a record of protrusive relation and what function does it serve after it is made?
What do you mean by interocclusal record?
interocclusal record. [-əklo̅o̅′səl] an imprint of the positional relation of opposing teeth or jaws to each other, made of the surfaces of occlusal rims or teeth with a material such as plaster of paris, wax, zinc oxide-eugenol paste, an elastomeric material or acrylic resin.
What kind of wax is a protrusive record made of?
From this record, along with a sound facebow, centric record and accurate casts, the articulator is now a jaw simulator for that patient. Historically, the protrusive is made with Master wax from Great Lakes Orthodontics, a rigid wax made malleable when needed.
What can be extrapolated from the protrusive record?
The protrusive record allows a clinician to extrapolate all mandibular movements: maximum intercuspal position (MIP), protrusive end to end, lateral excursive, and the pathways to them. Of course I mean all mandibular movements but the seated condylar position as well as how the mandible works against the maxilla.
How is the protrusive record used in surgery?
For those of you new to using this record, you will soon find that even condylar settings on a single patient may vary dramatically, from left to right. The protrusive record allows a clinician to extrapolate all mandibular movements: maximum intercuspal position (MIP), protrusive end to end, lateral excursive, and the pathways to them.
