Abstract: The invention relates to a device intended for connecting a prosthesis to a dental implant or directly to the jawbone of a patient, of the type including a pier (1) provided with a frustoconical head (13) with a half-cone angle (A) and a linking capsule (3) provided with a frustoconical cavity (31) suitable for receiving said head. The device according to the invention is essentially characterised in that the value of the angle (A) is equal to that of the angle (B), which corresponds to the maximum angle of an implant belonging to a single jaw, such that the cone distances of the conical portions of any pair of heads (13) and capsules (3) belonging to a single prosthesis (4) are never undercut relative to the path of insertion (Z) of said prosthesis, only using a single type of capsule and not having to observe any specific location or angle for each pier or each capsule during prosthesis implantation.

Abstract: The present invention relates to a method for making metal frameworks for dental protheses:of the type comprising metallic cops, optionally coated with resin or ceramic material, designed to be anchored in the mouth directly onto the stump of the tooth or teeth to be restored, contiguous or independent,optionally coupled by also metal intermediate members;using for the embodiment of said cops directly on the master mould, generally of plaster, obtained from the patient maxilla or mandibular cast, i.e. without having to pass through a duplicate in refractory material, first a thin metal sheet forming operation on the stump model of the tooth to be restored and then wintering and/or melting operation of precious, semiprecious and non-precious metal powder, coating said metal sheet, through the effect of a suitable heat supply.

Abstract: A denture-retaining male coupling portion (5) is fixed to a tab (4) which is itself glued to an inside face of an anchor tooth (1). The denture includes a metal plate having a corresponding female coupling portion (6). There is no need to use clasps or to remove healthy tissue from the anchor teeth.
