Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
A denture frame comprising a pair of posterior endosseous blade type implants inserted directly into the bone of the ascending ramus and body of the mandible, the implants being of malleable material and shaped to conform to the angle of the mandible, slots cut in the outer end of each posterior implant, an anterior endosseous blade implant shaped to conform to the curvature of the mandible, slots cut in each end of the anterior implant, a pair of support bars for supporting a denture, the bars being oppositely curved so that each bar will conform to the shape of one side of the mandible, and spring clip locking means cooperating with the slots on both ends of the anterior implant and on the ends of both posterior implants to lock the support bars in place when the support bars are inserted in the slots and therefore extend from the anterior implant to the posterior implant.

Claim 3
Dependent Claim

A denture frame comprising a pair of blade type posterior implants with recesses cut in their outer ends, an anterior blade type implant with a recess cut in each end thereof, a pair of support bars for the denture extending between the posterior and anterior implants and curved to fit the mouth of a wearer, the ends of said support bars resting in the recesses cut in the ends of the posterior and the anterior implants, a groove in each end of the support bars where they fit into the implant recesses, and locking devices to hold each support bar in each implant recess, each locking device being an inverted U-shaped spring steel clip to rest in the groove in the support bar and to encompass the support bar and the implant, the locking device having transversely extending projections on the ends of its legs to lock under the bottom of the implant.
