Abstract
This invention relates to improved methods and apparatus for recording and simulating the condylar movement of an individual. This invention also provides a dental articulator which is designed to simulate the jaw or condylar movements of a patient. This instrument enables a dentist to obtain the necessary diagnostic information for treatment of the occlusal irregularities, such as malocclusion, and the fabrication of dental cast or “dentures”.
Claims9
A method for making dental restorations using a dental articulator comprising an upper frame for simulating the upper dental arch and a lower frame for simulating the lower dental arch, a pair of condyles on the lower frame, one or more removable condylar tables received in the upper frame, an incisal pin on the upper frame, and a removable anterior guide table received in the lower frame, the pair of condyles configured to be moveable in the one or more removable condylar tables to allow movement of the upper frame and the lower frame with respect to each other, the incisal pin configured to interact with the removable anterior guide table, the method comprising:
- producing an impression of a patient's dentition;
- recording functional dynamics of occlusion to create a functionally generated path record;
- producing a model of the patient's upper dental arch and lower dental arch;
- placing the model of the upper arch and the lower arch in the dental articulator;
- placing the functionally generated path record in the dental articulator;
- filling the removable condylar tables and removable anterior guide table with a malleable material;
- and
- manipulating the model of the upper dental arch and the lower dental arch to scribe a path into the malleable material.
A method for making dentures using a dental articulator comprising an upper frame for simulating the upper dental arch and a lower frame for simulating the lower dental arch, a pair of condyles on the lower frame, one or more removable condylar tables received in the upper frame, an incisal pin on the upper frame, and a removable anterior guide table received in the lower frame, the pair of condyles configured to be moveable in the one or more removable condylar tables to allow movement of the upper frame and the lower frame with respect to each other, the incisal pin configured to interact with the removable anterior guide table, the method comprising:
- producing an impression of a patient's upper arch and lower arch;
- measuring the intraoral spacing between the upper and lower jaw and the lip line;
- placing the model of the upper arch and the lower arch in the dental articulator using the previously measured intraoral spacing;
- creating a curved transfer rim comprising a tongue and record area, the record area comprising a transfer material;
- recording, on the record area of the curved transfer rim, functional dynamics of occlusion of the patient to create a functionally generated path record;
- balancing the curved transfer rim to the patient;
- placing the curved transfer rim in the dental articulator;
- filling the removable condylar tables and removable anterior guide table with a malleable material;
- and
- manipulating the curved transfer rim within the articulator to scribe a path into the malleable material.
