Abstract
Abstract An intramucosal insert and method of retaining a denture utilizing the same. The intramucosal insert comprises a metallic projection having a dome-shaped head adapted to be seated within the mucosal tissue surrounding the jawbone of a patient, a planar base having top and bottom surfaces and contiguous side edges and an elongated neck having a cross section narrower than the cross section of the head connecting the head and the base. In utilizing the intramucosal insert, the base is secured in position in the denture, with the neck and head portions projecting outward therefrom. An elongated bore is formed in a mucosal tissue having a diameter proximate the cross-section of the neck of the insert. An enlarged cavity is formed at the interior end of the bore in the mucosal tissue having a shape proximate the shape of the head of the insert with a bottom surface extending outward from the sides of the bore to define a seat for the bottom surface of the head of the insert.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
85 words
An intramucosal insert for securing a denture in the mucosal tissue surrounding the jawbone of a patient comprising: a dome-shaped head adapted to be seated within the mucosal tissue; a planar base having top and bottom surfaces and contiguous side edges; a plurality of grooves formed in the side edges of the base extending between the top and bottom surfaces of the base; and an elongated neck having a cross section narrower than the cross section of the head connecting the head and the base.
Claim 2
Dependent Claim
85 words
An intramucosal insert for securing a denture in the mucosal tissue surrounding the jawbone of a patient comprising: a dome-shaped head adapted to be seated within the mucosal tissue; a planar base having top and bottom surfaces and contiguous side edges; a plurality of grooves formed in the side edges of the base extending between the top and bottom surfaces of the base; and an elongated neck having a cross section narrower than the cross section of the head connecting the head and the base.
Claim 3
Independent Claim
196 words
A method for securing a denture in the mucosal tissue surrounding the jawbone of a patient comprising the steps of: forming a cavity in the denture; depositing an ethyl cyanoacrylate cement in the cavity; securing an instramucosal insert having a dome-shaped head, a planar base having top and bottom surfaces and contiguous side edges and an elongated neck having a cross section narrower than the cross section of the head connecting the head and the base in the denture in the cavity formed in the denture; forming a first, elongated bore in the mucosal tissue having a diameter proximate the diameter of the neck of the insert; forming an enlarged cavity at the interior end of the first bore in the mucosal tissue having a shape proximate the shape of the head of the insert with a bottom surface of the cavity extending outward from the side edges of the first bore to define a seat for the bottom surface of the head of the insert; and inserting the head and neck of the insert into the first bore and cavity until the head seats within the cavity to secure the denture in the mucosal tissue.
Claim 4
Independent Claim
196 words
A method for securing a denture in the mucosal tissue surrounding the jawbone of a patient comprising the steps of: forming a cavity in the denture; depositing an ethyl cyanoacrylate cement in the cavity; securing an instramucosal insert having a dome-shaped head, a planar base having top and bottom surfaces and contiguous side edges and an elongated neck having a cross section narrower than the cross section of the head connecting the head and the base in the denture in the cavity formed in the denture; forming a first, elongated bore in the mucosal tissue having a diameter proximate the diameter of the neck of the insert; forming an enlarged cavity at the interior end of the first bore in the mucosal tissue having a shape proximate the shape of the head of the insert with a bottom surface of the cavity extending outward from the side edges of the first bore to define a seat for the bottom surface of the head of the insert; and inserting the head and neck of the insert into the first bore and cavity until the head seats within the cavity to secure the denture in the mucosal tissue.
Claim 5
Dependent Claim
68 words
The method of claim 2 further including: disposing a transferrable indicia means around the cavity forming in the denture prior to emplacement of the insert therein; placing the denture in position on the mucosal tissue such that the indicia means is transferred to the mucosal tissue to indicate the proper location of the first bore; and forming the first bore at the indicated position in the mucosal tissue.
