  • System and method for mass custom manufacturing of dental crowns and crown components
    Patent number: 8751031
    Abstract: A Mass Custom Manufacturing System and methods are provided. A single master file is created for a restoration (or multiple restorations for a single patient) from a scan. Copings/cores, abutments and other companion pieces are designed using the master file through a deconstruction method allowing for simultaneous CAM of those pieces. A centralized system controls design and manufacturing, allowing the system to “learn” from feedback from the CAM operations of prior pieces and incorporate such feedback into the design phase.
    Type: Grant

  • High strength substructure reinforcement for crowns and bridges
    Patent number: 7690920
    Abstract: A reinforcement for a dental restoration substructure is provided. The reinforcement is a generally annular structure that protrudes from the body of the substructure generally near an occlusal portion of the restoration. The annular structure provides a support for veneering porcelain at the location of the greatest thickness of the porcelain and at the location where occlusal stress is applied, and fractures of veneering porcelain are commonly experienced.
