Abstract
Abstract An implant designed to be mounted specifically in the ramus or retromolar portion of the mandible or jawbone, having an elongated main body carry a post extending up from the forward end of the main body and passing up through the epithelium; the main body of the implant being inserted into a partial incision made in the bone in a direction extending longitudinally and rearwardly, and driven in through and rearwardly beyond the incision and in beneath the top surface of the ramus; the main body of the implant extending rearwardly spaced a safe distance above the alvealor nerve and positioned between the signal lingual and buccal cortical plates of the ramus.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
The method of mounting an implant in the ramus portion of the mandible bone which comprises using an implant having a narrow elongated body portion with an upwardly curved bottom edge and a denture-anchoring post extending up from the forward end of said body portion, cutting a longitudinal slit in the mandible at a predetermined area at the back of the mandible, making the width of said slit corresponding to the width of the body portion of the implant, the depth of the slit not exceeding approximately 1 mm. the depth of said body portion, but the length of said slit being less than three-fourths of the length of said body portion, inserting the section of said implant body portion opposite said post-carrying end into said slit, and tapping said body portion for the remainder of its length beyond said slit into the ramus and in between the lingual and buccal cortical plates of the ramus, while maintaining the curved bottom edge of said body portion a desired distance above the alvealor nerve, until said body portion is entirely embedded in the mandible.
Claim 2
Independent Claim
183 words
The method of mounting an implant in the ramus portion of the mandible bone which comprises using an implant having a narrow elongated body portion with an upwardly curved bottom edge and a denture-anchoring post extending up from the forward end of said body portion, cutting a longitudinal slit in the mandible at a predetermined area at the back of the mandible, making the width of said slit corresponding to the width of the body portion of the implant, the depth of the slit not exceeding approximately 1 mm. the depth of said body portion, but the length of said slit being less than three-fourths of the length of said body portion, inserting the section of said implant body portion opposite said post-carrying end into said slit, and tapping said body portion for the remainder of its length beyond said slit into the ramus and in between the lingual and buccal cortical plates of the ramus, while maintaining the curved bottom edge of said body portion a desired distance above the alvealor nerve, until said body portion is entirely embedded in the mandible.
Claim 3
Independent Claim
267 words
The method of mounting an implant in the ramus portion of the mandible bone which includes using an implant having a narrow, elongated body portion with an upwardly curved bottom edge and a sharp lip protruding for a short distance from the forward end of said body portion and a denture-anchoring post extending up from the forward end of the body portion, and which method also consists in cutting a longitudinal slit in the mandible at a predetermined area in the back of the mandible, making the width of said slit corresponding to the width of the body portion of the implant, the depth of the slit not exceeding approximately 1 mm. the depth of said body portion, but the length of said slip being less than three-fourths of the length of said body portion, inserting the section of said implant body portion opposite the post-carrying end into said slit, tapping said body portion for the remainder of its length beyond said slit into the ramus and in between the lingual and buccal cortical plates of the ramus while maintaining the curved bottom edge of said body portion a desired distance above the alvealor nerve, until said body portion is entirely embedded in the mandible, and finally tapping said body portion in the reverse direction sufficiently to cause said sharp lip at the forward end of said body portion to be thrust forwardly into the cortical mesial bone structure in front of said longitudinal slit, thereby preventing any possibility of the forward end of said body portion subsequently being slightly lifted from its bed in the mandible.
Claim 4
Independent Claim
267 words
The method of mounting an implant in the ramus portion of the mandible bone which includes using an implant having a narrow, elongated body portion with an upwardly curved bottom edge and a sharp lip protruding for a short distance from the forward end of said body portion and a denture-anchoring post extending up from the forward end of the body portion, and which method also consists in cutting a longitudinal slit in the mandible at a predetermined area in the back of the mandible, making the width of said slit corresponding to the width of the body portion of the implant, the depth of the slit not exceeding approximately 1 mm. the depth of said body portion, but the length of said slip being less than three-fourths of the length of said body portion, inserting the section of said implant body portion opposite the post-carrying end into said slit, tapping said body portion for the remainder of its length beyond said slit into the ramus and in between the lingual and buccal cortical plates of the ramus while maintaining the curved bottom edge of said body portion a desired distance above the alvealor nerve, until said body portion is entirely embedded in the mandible, and finally tapping said body portion in the reverse direction sufficiently to cause said sharp lip at the forward end of said body portion to be thrust forwardly into the cortical mesial bone structure in front of said longitudinal slit, thereby preventing any possibility of the forward end of said body portion subsequently being slightly lifted from its bed in the mandible.
Claim 5
Dependent Claim
162 words
A dental implant designed specifically for insertion rearwardly into the ramus portion of the jawbone through an incision substantially along the longitudinal centerline of the bone ahead of the ramus portion, said implant having a substantially flat body portion with a width of approximately 2 mm., a depth not exceeding 6 mm. and an overall length of at least 30 mm., said body portion having an upwardly curved bottom edge, the top and bottom edges of said body poRtion converging at the rear end of said body portion to form a tip for facilitating the driving of the rear portion of said body portion rearwardly into the ramus, and an integral post extending up from the forward end of said body portion and adapted, when said body portion is implanted in the bone, to extend up through the epithelium to provide a denture anchorage, the angularity between said post and the top edge of said body portion being no greater than 90*.
Claim 6
Dependent Claim
162 words
A dental implant designed specifically for insertion rearwardly into the ramus portion of the jawbone through an incision substantially along the longitudinal centerline of the bone ahead of the ramus portion, said implant having a substantially flat body portion with a width of approximately 2 mm., a depth not exceeding 6 mm. and an overall length of at least 30 mm., said body portion having an upwardly curved bottom edge, the top and bottom edges of said body poRtion converging at the rear end of said body portion to form a tip for facilitating the driving of the rear portion of said body portion rearwardly into the ramus, and an integral post extending up from the forward end of said body portion and adapted, when said body portion is implanted in the bone, to extend up through the epithelium to provide a denture anchorage, the angularity between said post and the top edge of said body portion being no greater than 90*.
Claim 7
Dependent Claim
69 words
The ramus implant of claim 3 with said body portion formed with a plurality of holes extending laterally therethrough, and with the addition of a pointed lip extending from the front end of said body portion for a distance of approximately 3 mm., adapted to extend forwardly from the bone incision and under the cortical mesial bone structure when the implant is tapped forwardly after insertion into the ramus.
