Abstract:
Certain configurations of methods which can be used to produce removable oral devices are described. In some instances, the removable oral devices can be produced using molding, digital scanning, on demand printing and/or other processes. In certain examples, the produced removable oral device can be used in weight management, athletic performance or in other applications.
Abstract:
The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment placement structure. One dental attachment placement apparatus includes a body having an attachment placement surface that is to be placed on an attachment affixing surface of a tooth and wherein the attachment placement surface includes a portion that is shaped to allow placement of an attachment at a particular position on the affixing surface of the tooth and a portion of the body having a contour that is shaped to correspond with a contour of an alignment surface of a tooth and when the contour of the body and the corresponding contour is aligned, the attachment is located at the particular position and can be secured to the affixing surface of the tooth.
Abstract:
A method of building up a dental object includes steps of (i) determining the three-dimensional shape of the object; (ii) mixing at least a first and a second component to form a hardenable composition; (iii) depositing the hardenable composition through a nozzle; (iv) performing steps (ii) and (iii) in combination with moving the nozzle by computer control based on said data. The invention helps providing an object like a dental restoration at maximized geometric and optical quality.
Abstract:
Method of identification of the positioning of references in the construction of orthodontic appliances; it contemplates the use of a single positioning body both for positioning the analogs and for guiding the fitting of miniscrews in the patient's mouth. The use of the positioning body as a positioning means of the analogs on the initial plaster mold is prior to the use as a reference guide for fitting the miniscrews in the patient's mouth. The positioning element is implemented starting from a virtual image obtained by digital scanning of a model of the arch or oral imprint and software overlapping of one or more CAT images (CBCT); said virtual image also containing one or more references for positioning virtual miniscrews, and wherein said virtual miniscrews also identify the position of the reference analogs on which the orthodontic appliance should be constructed.
Abstract:
Systems, methods, and devices for producing appliances for expansion of the arch or palate of a patient are provided. In one aspect, a palate expanding orthodontic appliance comprises a teeth engagement portion comprising a plurality of teeth engagement structures and a force generating portion coupled to the teeth engagement portion and configured to apply force to cause the patient's palate to expand. In another embodiment, an arch expanding appliance comprises a force generating portion to apply an arch expansion force and a retention portion to hold the force generating portion on the teeth. The force generating portion is stiffer than the retention portion. The orthodontic appliances can be designed according to the specifications provided herein and manufactured using direct fabrication methods.
Abstract:
본 발명은 기준 플레이트를 이용하여 CT 데이터와 STL 데이터를 결합함으로써 치아 구조 및 잇몸 구조에 대한 하이브리드 영상을 획득하는 임플란트 영상 생성 방법을 제안한다. 이를 위해 본 발명은 임플란트 영상을 생성하고 디스플레이장치에 재생하는 임플란트 영상 생성 시스템에 의해 수행되며, 환자의 구강에 기준 플레이트를 구비하는 바이트가 삽입되었을 때 획득되는 CT(Computed Tomography) 데이터 및 치아 석고 본(Plaster Patterns of Teeth)을 참조하여 폴리곤으로 입체를 표현하는 STL(STereo Lithography) 데이터를 획득하는 단계, CT 데이터의 기준 플레이트와 STL 데이터의 기준 플레이트 좌표를 일치시킨 후, STL 데이터를 기준으로 CT 데이터를 보정하는 단계 및 보정된 CT 데이터는 제1밀도의 영역을 표현하도록 하고, STL 데이터는 제2밀도의 영역을 표현하도록 하는 하이브리드 영상을 생성하는 단계로 구성될 수 있다.
Abstract:
A method of making a customized dental blank comprises the steps of providing individual tooth color information, forming an open-celled dental blank precursor, providing the open-celled dental blank precursor with color in accordance with the individual tooth color information, and compressing the dental blank precursor. The method helps maximizing the optical quality of dental restoration at minimized costs.
