  • Patent number: 10085819
    Abstract: A dental drill system is provided, comprising a drill having a drilling part with a first end configured for drilling a hole in a jaw bone and a shank part with a second end configured for connection to a drill-rotating device and a guiding sleeve for guiding the drill. The guiding sleeve has a first side facing the drill-rotating device and a second side intended to face the jaw bone during a drilling operation. A guiding through-hole extends from the first side to the second side. A rim also extends at least partly around the circumference of the drill, and the system comprises a drill stop sleeve provided with a recess extending circumferentially around an inner side of the drill stop sleeve, allowing the drill stop sleeve to be snap-locked onto the drill. The guiding sleeve also comprises a flange that defines an end position for the drill stop sleeve.

  • Patent number: 10022206
    Abstract: A method, system, and dental prosthesis are provided to facilitate simulation of the natural appearance of teeth. The prosthesis can be formed to include a component to which an aesthetic coating, such as a coloring or tint, can be applied. Further, the prosthesis can include a porcelain coating disposed on the outer surface thereof, and on top of the aesthetic coating, such that the aesthetic coating can be visible through the porcelain coating of the prosthesis. During production, the crown can be coated with a metal and/or ceramic powder by means of a powder printer that can be controlled by computer equipment. A practical and rapid application function can be obtained to produce an extremely natural-looking result.

  • Patent number: 8500448
    Abstract: A model of at least a part of a dental structure, an articulator, and methods of manufacturing such devices are provided. The model and the articulator can be used to approximate the natural movements of a jaw of a patient to facilitate preparation of a dental restoration. The model can include the dental structure, an interface, and at least one void extending from a reference surface of the interface inwardly toward the void. The articulator can include upper and lower portions on which models of upper and lower dental structures can be held. The upper and lower portions of the articulator can be configured to generally maintain a vertical alignment while at least one gap formed between respective first and second alignment components thereof allows horizontal movability of the upper and lower portions relative to each other to test the interfit of the models therebetween.

  • Patent number: 8457772
    Abstract: Presented herein are methods and devices for designing dental components, such as physical models of a patient's anatomy, crowns and bridges. An operator of a prosthetic designing system can receive information, such as from a scanner, which provides information on the topology of the patient's dentition. The operator can use this information to design a custom prosthetic to fit the patient. Part of the designing process involves using a finish line defined for a preparation as a segmentation line for a physical die corresponding to the preparation, and using a path of draw line as an insertion axis line for a dental prosthetic.

  • Patent number: 7925374
    Abstract: A system for production of a dental crown (23, 24) includes identification equipment (2), modeling equipment (9), ordering equipment (6), and an automated production arrangement (16). The latter, as a function of one or more first information items, is arranged to effect production, by means of pressing or pressure-casting, of an integrated dental crown which is made up of two layers. The first layer comprises or consists of porcelain material, and the second layer consists of aluminum oxide, zirconium oxide, etc. The second layer forms a cap, via which the dental crown can be applied to a tooth stump (28) of a patient (1). The invention also relates to a dental replacement component consisting of the dental crown.
