Abstract

Abstract An incisor block for mounting on the lingual surface of an incisor to produce separation between the upper and lower posterior teeth in deep bite patients. The incisor block has a block body and a positioning cap. The block body has a mounting surface designed to closely abut the lingual surface of the incisor, a biting surface and a thickness. Proximate to the incisor and extending toward the incisal surface when the block is mounted on the incisor is a positioning cap having a notch and a facial extension. Ferromagnetic recovery fragments may be positioned within the block body and positioning cap. The block is installed on the incisor by the method of first etching the tooth before placing an adhesive bonding agent on the etched tooth surface and the mounting surface of the incisor block. The incisor block is placed into position by placing the positioning cap against the incisal edge and pressing the mounting surface against the incisor's lingual surface. Positive placement is facilitated by engagement of the notch with the incisal edge. Once the adhesive is cured, the positioning cap of the incisor block may be fractured off with pliers and then trimmed to remove any rough material from the block body.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 100 words
An incisor block to aid posterior tooth eruption to a desired occlusal plane by mounting on the lingual surface of an incisor, said incisor block comprising: a. a block body defined by a mounting surface, a thickness, and a biting surface, said biting surface defining a plane substantially parallel to said occlusal plane when said mounting surface is proximately attached to said lingual surface; b. a positioning cap attached to said block body, said positioning cap being attached to said block body at a notch; and c. a block recovery fragment embedded wholly within the interior of said block body.
Claim 2
Dependent Claim 100 words
An incisor block to aid posterior tooth eruption to a desired occlusal plane by mounting on the lingual surface of an incisor, said incisor block comprising: a. a block body defined by a mounting surface, a thickness, and a biting surface, said biting surface defining a plane substantially parallel to said occlusal plane when said mounting surface is proximately attached to said lingual surface; b. a positioning cap attached to said block body, said positioning cap being attached to said block body at a notch; and c. a block recovery fragment embedded wholly within the interior of said block body.
Claim 3
Dependent Claim 17 words
The incisor block of claim 1 further comprising a cap recovery fragment embedded within said positioning cap.
Claim 4
Independent Claim 106 words
The method of installing an incisor block on an incisor having an incisal edge and a lingual surface, said incisor block comprising a block body and a positioning cap, said block body having a mounting surface, thickness and a biting surface, said positioning cap having a notch, said method comprising: a. etching said lingual surface of said incisor; b. applying adhesive to said mounting surface while leaving said positioning cap free of adhesive; c. positioning said notch against said incisal edge; d. pressing said incisor block against said lingual surface; e. allowing said adhesive to cure; and f. removing said positioning cap from said block body.
Claim 5
Independent Claim 106 words
The method of installing an incisor block on an incisor having an incisal edge and a lingual surface, said incisor block comprising a block body and a positioning cap, said block body having a mounting surface, thickness and a biting surface, said positioning cap having a notch, said method comprising: a. etching said lingual surface of said incisor; b. applying adhesive to said mounting surface while leaving said positioning cap free of adhesive; c. positioning said notch against said incisal edge; d. pressing said incisor block against said lingual surface; e. allowing said adhesive to cure; and f. removing said positioning cap from said block body.
Claim 6
Dependent Claim 30 words
The method of installing an incisor block of claim 3, further comprising the step of embedding a block recovery fragment wholly within said block body before etching said lingual surface.
Claim 7
Dependent Claim 29 words
The method of installing an incisor block of claim 3, further comprising the step of mounting a cap recovery fragment within said positioning cap before etching said lingual surface.
Claim 8
Dependent Claim 51 words
An incisor block comprising: a. a block body defined by a mounting surface, a thickness, and a biting surface; b. a positioning cap attached to said block body, said positioning cap being attached to said block body at a notch; and c. a block recovery fragment embedded within said positioning cap.
Claim 9
Dependent Claim 51 words
An incisor block comprising: a. a block body defined by a mounting surface, a thickness, and a biting surface; b. a positioning cap attached to said block body, said positioning cap being attached to said block body at a notch; and c. a block recovery fragment embedded within said positioning cap.
Claim 10
Dependent Claim 17 words
The incisor block of claim 6 further comprising a block recovery fragment embedded within said block body.
