    摘要: An intraoral scanning system comprises an intraoral scanner and a computing device. The intraoral scanner is to configured to generate intraoral scan data of a bite of a patient. The computing device is configured to receive the intraoral scan data of the bite of the patient during scanning of the bite of the patient, wherein each datum of the intraoral scan data shows a portion of a lower dental arch and a portion of an upper dental arch of the patient. The computing device determines a difference in a relative position of the lower dental arch to the upper dental arch between at least a first datum of the intraoral scan data and a second datum of the intraoral scan data and performs a remedial action responsive to determining that the difference in the relative position of the lower dental arch to the upper dental arch exceeds a difference threshold.

    摘要: A system determines the optimal vertical and horizontal position of a patient's mandible for properly fitting an oral appliance for the treatment of obstructive sleep apnea or other conditions. Existing systems are difficult to use and result in inaccurate measurements. The present invention includes a double-sided vertical gauge for determining vertical adjustment, a set of progressively-sized keys for determining horizontal adjustment, and an arch fork. The unique designs of the vertical gauge and the keys facilitate easier and more accurate measurements.

    摘要: A detection apparatus includes input interface circuitry to which upper jaw tooth row data, lower-jaw tooth row data and occlusion data are to be input, and processing circuitry configured to detect a premature contact position by generating synthetic data indicating a synthetic three-dimensional shape of upper and lower rows of teeth in the occlusal state by synthesizing the upper-jaw tooth row data and the lower-jaw tooth row data using the occlusion data as a reference and updating at least one tooth row data of the upper-jaw tooth row data and the lower-jaw tooth row data included in the synthetic data so that a state of the upper and lower rows of teeth is displaced from the occlusal state to the open state.

    摘要: A bone foundation guide system has a bone foundation guide including a body that is contoured to reversibly affix to a bone segment of a dental implant surgical site. The body is further contoured to guide the cutting of a portion of the bone segment from a dental implant surgical site and alternatively support a dental implant surgical guide. The body is further contoured to support a bone foundation guide prosthesis as an alternative to the dental implant surgical guide. The bone foundation guide prosthesis combines with the body to accommodate the bone segment portion as placed through the body prior to the bone segment portion being removed from the dental implant site through the use of the body.

    摘要: Disclosed is a computer-implemented method of using a dynamic virtual articulator for simulating occlusion of teeth, when performing computer-aided designing of one or more dental restorations for a patient, where the method includes the steps of: providing the virtual articulator including a virtual three-dimensional model of the upper jaw and a virtual three-dimensional model of the lower jaw resembling the upper jaw and lower jaw, respectively, of the patient's mouth; providing movement of the virtual upper jaw and the virtual lower jaw relative to each other for simulating dynamic occlusion, whereby collisions between teeth in the virtual upper and virtual lower jaw occur; wherein the method further includes: providing that the teeth in the virtual upper jaw and virtual lower jaw are blocked from penetrating each other's virtual surfaces in the collisions.

    摘要: An intraoral scanner includes an image capturing device and a processor. A method of operating the intraoral scanner includes the image capturing device sequentially capturing M images of a buccal bite, the processor generating M sets of buccal bite point clouds according to the M images, the processor matching the M sets of buccal bite point clouds to generate a bite model, when the number of data points of the bite model exceeds a first threshold, the processor computing P sets of bite feature descriptors of the bite model, when a predetermined quantity of bite feature descriptors in a set of bite feature descriptors of the P sets of bite feature descriptors exceeds a second threshold, the processor performing a registration on an upper arch model and a lower arch model to the buccal bite mode to generate a full mouth model.
