摘要： The dental locking clasp member comprises a U-shaped piece having twin arms with substantially flat parallel opposing inner surfaces connected to an anchor portion having a plurality of anchor grooves. The twin arms have twin opposing locking recesses adjacent the free ends. Additional auxiliary parts may be part of the locking clasp member and include a bar portion with a curved spur, a receptacle portion which has locking projections which engage in the locking recesses in the case of a labial locking clasp and a clasp stem also with locking projections with a stop in the case of a buccal locking clasp. When the additional auxiliary parts are made of wax the entire locking clasp member may be used with a wax pattern to produce a completed partial casting with the appropriate locking clasp in a single casting operation which does not require reworking.

摘要： A distal extension hinged stress breaker for a dental appliance which prevents lateral movement of the hinge. A shank portion is pivotally coupled to a head portion at one end thereof and a rear portion covers the opposite end thereof. The head portion is adapted to be coupled to an attachment for existing teeth, while the rear portion is adapted to be coupled to a case which fits over the mouth ridges and supports artificial teeth. The head portion includes free ends which can be distorted to provide a tight fit against the shank portion and prevent lateral movement of the shank portion with respect to the head portion.
