Definitions

  • Pattern framework for forming a dental prosthesis comprising pillars and method for fabricating such pattern framework
  • the present invention relates to frameworks for dental prostheses produced either by conventional dental laboratory procedures including CAD/CAM or by virtual technology. More specifically, it relates to a framework using a uniquely designed set of prosthetic teeth specific to the individual tooth position.
  • a pattern framework for a dental prosthesis is a unified metal or ceramic base structure consisting of a horizontal arch on which vertical posts, specific to the teeth they support are rigidly connected.
  • This pattern framework can be supported by dental implants, root anchors placed in the jawbone or without any support.
  • Such a framework is securely fixed to the jaw by screwing or cementing it onto the implants.
  • the framework supports the specifically designed replacement teeth which are fused to the posts of the pattern framework with a luting cement or any other processing to achieve a bond.
  • the prosthesis containing this pattern framework is patient-specific and must meet the strict requirements of accuracy to reach an optimal fit at the prosthesis/implant interface to distribute chewing and grinding forces appropriately to the underlying jawbone and avoiding high stresses to the underlying bone which could cause implants to deintegrate from the bone.
  • the fit of the pattern framework to the supporting implants should be 50 microns or less.
  • the framework is capable of replacing all the teeth in a dental arch, and because the framework connects the occlusal surfaces of the replacement teeth to the osseointegrated dental implants, the dimensions of the pattern framework are generally larger in comparison to traditional dental prostheses like crowns and tooth-supported bridges.
  • the pattern framework is designed to support not only replacement teeth but also the bone and gum tissue that previously immediately surrounded the missing teeth.
  • a conventional dental laboratory method for creating these pattern frameworks is based on the manual design of a physical model of the pattern framework in wax or resin and the production of the pattern framework by means of lost wax casting or copy milling. These previous methods of framework production can be highly precise however they require very skilled dental laboratory technicians doing time-consuming modelling of the frame, a process that is inefficient and costly.
  • the traditional lost wax process is very lengthy and highly labor intensive, consisting of many manual steps that include the design, manual contour and fabrication of the wax pattern, investing the pattern in a refractory mold, melting and evaporating the wax pattern in a high temperature burn out oven over many hours, melting the metal or similar material and casting or pressing it into the pattern mold, divesting the solidified metal framework and refining the surface of the framework to permit the next phase to begin.
  • a current alternative to the lost wax casting method of framework construction is the use of CAD/CAM technology to scan the wax or resin pattern frame and possibly design directly in the computer.
  • Pattern framework production by virtual technology is available but its ability to create tooth support mechanisms is limited.
  • the present disclosure concerns a pillar destined to be mounted on a pattern framework for forming a dental prosthesis, the pillar having a polygonal cross-section, a first end of the pillar being destined to cooperate with the pattern framework and the other end of the pillar comprising a sensibly flat surface.
  • the present disclosure further concerns a set comprising a plurality of the pillar, the set of the pillars being destined to be mounted on predetermined positions on the pattern framework; wherein a lateral size and polygonal cross-section of each pillar being determined by which predetermined positions the pillar is mounted on the pattern framework.
  • the present disclosure further concerns a duplicated set of teeth in which the pillar is destined to be mounted; each tooth comprising a crown socket, the crown socket having a polygonal cross section such that the pillar can be mounted fittingly in the corresponding crown socket.
  • the present disclosure further concerns a method for fabricating a pattern framework , comprising the steps of:
  • the denture set-up can be made by dental impression of the patient's maxillary and mandibular ridges.
  • the method can then further comprise a step of scanning the completed pattern framework to capture a digital impression of the 3D shape of it and to generate a digitalized version of the digital impression after manual adaptation since it is not possible at present to mill all the data in an accurate enough manner after scanning and capturing this data.
  • determining tooth setup positions, providing the pillars, removing the teeth, and forming the tooth supporting pattern arch can be performed numerically based on the scan capture of the denture set-up by using a computer-aided design (CAD) software.
  • the method can then further comprise a step of generating a digitalized version of the completed pattern framework.
  • the method further comprises using the digitalized version of the completed pattern framework to produce the final dental prosthesis by using a computer-aided manufacturing (CAM) technology.

  • the polygonal cross-section of the pillar 1 allows for the crown 6 to be mounted non- rotationally on the pillar 1 and such that the crown 6 can only be fitted on the pillar structure 1 in a single predetermined position. It is preferable to have no shoulder on the immediate primary structure 10, but to rather form the shoulder support from the secondary material to be added later.
  • Fig. 6 represents a front view of a conventional abutment 1 on which a crown 6 is fixed.
  • the abutment 1 is typically obtained by clinical tooth preparation such as to reduce a natural tooth into a roughly conical form. This preparation results in the formation of a shoulder 8 at the intersection between the abutment 1 and the horizontal arch 1 1.
