Abstract

An adapter device for extension of miniplates used in orthodontic treatments, which provides for the extension of the plate for the most anterior or posterior and superior or inferior positions, and also the fixation of orthodontic accessories, which can be used for various skeletal anchorage systems available on the market, pliers for the attachment of the device, and a method for extension and attachment of miniplates by use of the adapter devices of the present invention.

Claims

1. An adapter device for the extension of the miniplates, comprising:

i) a base for compression; and

ii) a master cylinder with an end thinner than the body,

wherein the master cylinder has an outer diameter that is smaller than a diameter of a hole of the miniplate and the base for compression has an outer diameter that is greater than the diameter of the miniplate hole.

2. The device according to claim 1, wherein the base for compression has a surface comprising a concavity.

3. The device according to claim 2, wherein the concavity is of conical shape.

4. Orthodontic pliers for fixing an adapter device for the extension of miniplates, the pliers having side, wherein each side of the pliers comprises a curved tip out of a plane of the side, the curved tips having an identical format to each other, wherein ends of each of the tips have projections which are embedded in the adapter device, the adapter comprising:

i) a base for compression; and

ii) a master cylinder with an end thinner than the body,

wherein the master cylinder has an outer diameter that is smaller than a diameter of a hole of the miniplate and the base for compression has an outer diameter that is greater than the diameter of the miniplate hole.

5. The pliers according to claim 4, wherein the projections have a base and an apex, and the base is wider than the apex.

6. The pliers according to claim 5, wherein the apexes touch each other when the pliers close.

7. A method for the extension and fixation of miniplates using an adapter device for the extension of the miniplates, the method comprising:

providing an adapter comprising;

i) a base for compression; and

ii) a master cylinder with an end thinner than the body,

wherein the master cylinder has an outer diameter that is smaller than a diameter of a hole of the miniplate and the base for compression has an outer diameter that is greater than the diameter of the miniplate hole, and

comprising the steps of;

a) positioning two of the miniplates so that the holes in the miniplates remain concentric;

b) inserting the adapter device in the holes in the miniplates, fixing both miniplates; and

c) compressing the base of the adapter device until a thinner end of the master cylinder is deformed to a diameter greater than the diameter of the miniplates.

8. The method according to claim 7, further comprising using at least two adapter devices for the miniplate.

9. The method according to claim 8, further comprising a step of fixing an orthodontic accessory before positioning the miniplates of step a).
