Abstract
The present invention provides a removable attachment for a partial denture with a sliding locking assembly. The locking assembly is provided with a relatively wide slot and narrower sliding slot or recess which has a major axis which is horizontal and at a right angle to the row of teeth, a locking member including a lock pin and a protruding member suitable for being retained in a recess of the denture and has a hole which may be engaged by the lock pin. The lock member is retained in position by a spring loaded pin and detent to receive the pin. The attachment may be easily operated by a fingertip without injury to the finger and no sudden separation of the partial denture is experienced. It may be used in cases where only the canine teeth of both sides exist as well as in cases where bilateral and/or unilateral teeth are missing. General dental instruments can be adapted for use with this attachment and no special instruments are necessary. The attachment can be fabricated from various standard dental materials and is reasonably economical.
