Abstract

Disclosed is a dental model articulator to connect the upper and the lower dental model casts. A mounting member is respectively mounted on each upper and lower cast, and a pair of elastic connecting members are connected to the mounting members. A vertical bar of the elastic connecting member has an S-type serpentine portion. The cast can smoothly move to the front, rear, left and right side by the S-type serpentine portion. A fastening member connects and disconnects the elastic connecting member and the mounting member by fastening a socket of the mounting member. A pivot member connects each elastic connecting member enabling to be pivoted. Whereby, the connecting ball of the elastic connecting member and the socket of the mounting member are connected by the fastening member, therefore the connecting ball can be connected to and disconnected from the socket.

Claims

1. A dental model articulator including a mounting member each connected to a upper and a lower dental model casts, a pair of U-type elastic connecting members connected to said mounting member, and a pivot member which pivotedly connects said pair of elastic connecting members, said dental model articulator comprises:

a mounting member having a mounting projection corresponding to a mounting recess formed on said cast and formed with an inserting space on the center thereof; and

an inserting member inserted into said mounting recess in a state where said inserting member is inserted into said mounting projection so that said mounting member is fixedly mounted on said cast enabling to be disconnected.

2. The dental model articulator as claimed in claim 1, wherein said inserting member is provided with a triangle projection being inserted into said mounting projection and a supporting plate supporting said triangle projection, and wherein the height h₂ of the portion, which is contacted to said supporting plate, in said triangle projection, is formed to be greater than the height h₁ of the inserting space formed on said mounting projection, so that said mounting projection is outwardly bent when said inserting projection is fully forcedly inserted into said mounting projection.

3. One of the dental model articulators as claimed in claims 1 or 2, wherein said elastic connecting member is provided with a serpentine portion on its predetermined position so that it is easily held.

4. A dental model articulator including a mounting member each connected to a upper and a lower dental model casts, a pair of U-type elastic connecting members connected to said mounting member, and a pivot member which pivotedly connects said pair of elastic connecting members, said dental model articulator comprises:

an elastic connecting member provided with plural S-type serpentine portions on a predetermined position thereof so that said cast moves to the front, rear, left and right side.

5. A dental model articulator including a mounting member each connected to a upper and a lower dental model casts, a pair of U-type elastic connecting members connected to said mounting member, and a pivot member which pivotedly connects said pair of elastic connecting members, said dental model articulator comprises:

a fastening member which is screwedly connected to the outer periphery surface of said mounting member and connects said mounting member to said elastic connecting member enabling to be disconnected;

a mounting member having a mounting projection corresponding to a mounting recess formed on said cast and formed with an inserting space on the center thereof;

an inserting member to be inserted in said mounting recess in a state where said inserting member is inserted into said mounting projection so that said mounting member is fixedly mounted on said cast enabling to be disconnected; and

an elastic connecting member provided with plural S-type serpentine portions on predetermined position so that said cast can move to the front, rear, left and right side.
