Abstract
Creating a denture by using the patient's mouth as an intra-oral articulator by use of an upper and/or lower dental impression tray for creating the impression of the edentulous mouth, the trays having platforms or support surfaces which magnetically hold a main frame therebetween. The orientation of the main frame is adjustable and lockable with respect to the lower tray all while within the mouth. Once the main frame is located and locked in place, artificial teeth formed with holding wax and a rearwardly extending fork are slid into a slot of the main frame and also locked. The wax holding the artificial teeth is then melted to integrate the teeth with formed respective upper and lower custom trays.
Claims7
A set of dental devices for use in creating artificial dentures using the patient's mouth as an intra-oral articulation mechanism comprising a) a palatal member shaped to the general shape of the palatal arch of the mouth of a patient b) a lower tray having an arcuate and inverted trough for use in creating a negative impression of the lower gums of the mouth of the patient, said lower tray comprising at least three inwardly directed and horizontally arranged, magnetic-attracting holding platforms and c) a mechanical frame which arcuately extends from a first side, across the front and then to the other side of the patient's mouth, said frame further comprising at least three vertically telescopic supports with magnetic ends, said supports being spaced apart as said holding platforms are spaced and a horizontal slit in said frame for accepting the adjustable placement of a rearward mechanical extension of a set of artificial teeth therein, said frame adapted to fit within the patient's mouth and said magnetic ends of said supports being magnetically supportable upon said holding platforms of said lower tray, said palatal member, lower tray and said frame having magnetic and mechanical connections for removably securing said palatal member to said frame and said lower tray to said frame and wherein said supports are adjustable in three dimensions, yet having a support locking mechanism holding the relative location of said magnetic ends of said supports with respect to said holding platforms of said lower tray and with respect to said palatal member.
A system for creating artificial teeth for a patient using the patient's mouth as an intra-oral articulator comprising:
- a lower dental tray for creating a dental impression of the lower gum ridge of the patient's mouth;
- an upper dental tray for creating a dental impression of at least a portion of the patient's upper mouth portion including the palatal arch;
- and
- an artificial-tooth holding device in contact with said lower dental tray and having selective adjustment about multiple degrees of movement and then fixed securement with respect to said lower dental tray while within the patient's mouth, said artificial tooth holding device further comprising a tooth holding, horizontal slit wherein one or more artificial teeth provided with a rearwardly projecting tine can slide into and are movable within said slit for initial adjustably holding and then securing artificial teeth thereon.
