Patent number: 10159547Abstract: Apparatus for three-dimensionally measuring a row of teeth, having, on a shaft, an autonomously movable measuring head including a central measuring member and at least two lateral measuring members movably interconnected and defining a variable measurement space. The head, placed on a row of teeth, is guided therealong using guiding elements. Measuring units in the measuring members measure structures in the measurement space. Measurements are taken from multiple solid angle positions of the measuring units, the positions being preset in the measuring members, being adjusted by moving the measuring members, being taken by having mirrors move, in a controlled manner, the beam path generated by the measuring units, or being aligned by changing the angular position of the head relative to the shaft in an automatically controlled manner.Type: GrantFiled: June 8, 2015Date of Patent: December 25, 2018Assignee: Quarz Partners AGInventors: Werner Mörmann, Albert Mehl

Patent number: 9672444Abstract: A method and apparatus related to forming prosthetic dental items or tooth restorations. A defective tooth, prosthetic dental item, or a dentition is scanned. A first electronic data set from a three-dimensional scan of a defective tooth, defective prosthetic dental item, or the dentition is generated, and one or more correspondence points or structure in the first electronic data set are assigned to one or more corresponding points or structures in a second electronic data set. The second electronic data set represents a tooth model. To generate a patient specific tooth model, the tooth model is adjusted such that a function which describes one or more distances between the one or more correspondence points or structures in the first electronic data set and the one or more corresponding points or structures in the second electronic data set is minimized.Type: GrantFiled: December 15, 2011Date of Patent: June 6, 2017Assignee: Dentsply International Inc.Inventor: Albert Mehl

Publication number: 20170119505Abstract: Disclosed is a measuring apparatus for three-dimensionally measuring a row of teeth, the rows of teeth of the maxilla and mandible, buccally, during articulation and during terminal occlusion, an alveolar ridge or the palate in the oral cavity, the measuring apparatus comprising an autonomously movable measuring head (1) on a shaft (4), said measuring head (1) consisting of a central measuring member (1.1) and at least two lateral measuring members (1.2, 1.3) which are movably interconnected and define a variable measurement space (6). The measuring head (1) can be placed on the row of teeth and is be guided therealong using guiding elements (1.1.1, 2.1, 2.2, 5); contact sensors (13) and angle sensors (16) ensure that the lateral measuring members are laterally guided and the angles thereof are adjusted to the topology of the alveolar ridge while the central guiding element (1.1.1) and/or a support (5) of the shaft (4) can rest on the row of teeth.Type: ApplicationFiled: June 8, 2015Publication date: May 4, 2017Applicant: Quarz Partners AGInventors: Werner MÖRMANN, Albert MEHL

Patent number: 8727776Abstract: The invention relates to a method for producing denture parts or for tooth restoration. According to said method, to reconstruct a tooth requiring repair or a defective condition, at least some of the missing exterior surfaces of denture parts or tooth restorations are adapted to the existing residual tooth material and/or the opposing teeth and/or the position of the neighbouring tooth and/or the occlusion position, by means of the optimisation of a generic dental-model data record of the desired tooth type, thus varying the linear factors of at least the most important components, (determined from the electronic data records of a larger number of measured tooth surfaces by primary axis analysis methods), in such a way that the selected optimisation criteria are fulfilled by the minimisation of an error function.Type: GrantFiled: November 10, 2003Date of Patent: May 20, 2014Assignee: Sirona Dental Systems GmbHInventor: Albert Mehl
