| 摘要 | Magnetic dental appliances and materials therefor, magnetic denture teeth, magnetic transfer apparatus and method magnetic denture material; and particularly magnetic methods and apparatus for making full dentures and bridges providing an accurate functional balance of occlusion and centric relation for use in the full denture and bridge construction, including the use of magnetic holding means for transferring the upper baseplate and lower bite rim in proper locked relationship to an articulator. Also, a method of retention of the dentures and bridges in place in the mouth during use by magnetic means is provided, including magnetic core artificial teeth, magnetic denture base material, and magnetic alloy inserts for implanting under the soft tissue along and into the alveolar ridge. | ||||||
| 权利要求 | 1. A method of making dentures including: forming upper and lower baseplates; mounting magnetic locking means on each of said baseplates in substantial centric relation in said baseplates; inserting the baseplates separately in a patient''s mouth holding the baseplates spaced from each other and then locking them together by means of said magnetic locking means in a position of vertical, centric and equalized contact with the tissue of the patient''s ridges determined by the structure of the patient''s chewing mechanism and fitting teeth on the denture baseplates to conform to the patient''s chewing mechanism. 2. A method of making dentures including: forming upper and lower baseplates; mounting a first magnetic member on one of said baseplates at a substantially centric position; mounting a second magnetic member on the other of said baseplates at a substantial centric position to coact with said first magnetic member to positively hold said baseplates spaced from each other and locked together by means of said magnetic members in a position determined by the structure of the patient''s chewing mechanism; holding said baseplates a position spaced from each other and locked together position by means of said magnetic members; determining a plane of occlusion for the patient between the baseplates; and fitting teeth on the denture bases to conform to the plane of occlusion and the relationship of the baseplates as held by said magnetic members. 3. A method of making dentures including: forming upper and lower baseplates, forming a wax bite rim on only the lower baseplate mounting magnetic locking means on each of said baseplates in substantially centric relation in said baseplates; disposing the baseplates with the magnetic locking means thereon in the patient''s mouth and closing the patient''s chewing mechanism to the proper centric and vertical occlusal relationship determined by the structure of the patient''s chewing mechanism; and locking said baseplates in such position by means of said magnetic locking means on said baseplates. 4. The method of claim 1 wherein the molar teeth on the lower baseplate are formed of magnetic material and the molar teeth on the upper baseplate are formed of magnetic material of like polarity whereby the teeth on the respective baseplates repel each other to bias the baseplate toward their respective alveolar ridges. 5. A method of the character set forth in claim 3 including the steps of: fitting teeth on one of said denture baseplates to substantially the occlusal plane of the patient in conformity with the patient''s chewing mechanism; building a bite rim on the other of said baseplates; building a soft wax bite surface or tracing surface on the bite surface of said bite rim; covering said soft wax surface with a thin nonadhesive protective film on the exposed surface of said soft wax surface; fitting said baseplate having the teeth thereon and the baseplate having the bite rim with the soft surface thereon in the patient''s mouth and moving the patient''s jaw to define with the teeth an occlusal plane tracing in the soft wax beneath the film on the bite surface of the bite rim on the other baseplate; and then forming a hard stone mold of the tracing formed in the soft wax surface. |
