Coupling device for dental prothesis

Details

Inventors: Graub, M. Walter;
Assignee: Metaux Precieux sa Metalor (Neuchatel, CH)
Primary Examiner: Wilson; John J.
Assistant Examiner:
Attorney, Agent or Firm:

A coupling for removable dental protheses comprising a male member one end of which is constituted by a fixing member, whereas the other end has the shape of a male coupling member and a female portion comprising a rigid casing fixed into the prothesis which houses a resiliently deformable mass provided with a housing intended to receive the male coupling member of the male portion. This resiliently deformable mass is maintained in the casing by a removable ring clipped on the casing so that the replacement of this mass is effected without any intervention on the prothesis. In one embodiment, the male coupling member is a cylinder connecting through a rib to a support and the female portion of the coupling comprises a cylindrical sleeve of resiliently deformable material maintained within the casing of the female portion of the coupling by a slotted ring, the ring comprising locking formations cooperating with corresponding formations of the casing and of the sleeve and fixing its angular service position with respect to these two parts. In another embodiment, the male coupling member is a sphere and the rigid casing is non-spherical, the resiliently deformable mass having a spherical cavity that receives and retains the sphere. The removable ring contacts and retains the resiliently deformable mass but is spaced from the male member.

DETAILED DESCRIPTION The present invention has for its object a coupling for removable dental prothese of the type of the one described in the patent CH 674.
926, but which, eliminates its major drawback.
The coupling for removable dental prothesis distinguishes itself by the fact that the resiliently deformable mass is maintained in the casing through a removable ring clipped or snapped onto the said casing so that the replacement of this mass is effected without any intervention on the prothesis in which the housing is fixed.
