Total Claims: 13
Claim 1
Independent Claim
166 words
Means facilitating the securement and location of an orthodontic attachment on a tooth, said means comprising in combination with an orthodontic attachment: a generally U-shaped securing device having a first leg, dimensioned to lie over one face of a tooth and releasably engaging the attachment to be secured in a desired location on the tooth face; a second leg spaced from said first leg and dimensioned to lie over a face of the tooth opposed to said one face, and a base connecting said first and second legs, said base dimensioned to extend over the biting surface of the tooth and biasing said legs toward said tooth faces to maintain said attachment in pressing contact with the faces of the tooth over which it has been selectively positioned, whereby the orthodontic attachment may be selectively held at a desired position on a tooth by engagement with one of said legs, with said device subject to selective removal after said attachment has become affixed to the tooth.
