摘要:
The invention provides a method for creating a physical teeth model comprising providing a virtual three dimensional (3D) image of a patient's dentition or part of it; and preparing a physical model of the jaws, based on information from said virtual 3D image, wherein said physical model is a positive model or a negative model from which a positive working model can be produced, said model comprising two members, one representing the upper jaw and the other the lower jaw, and both members are produced with markings or an alignment arrangement to permit proper occlusion alignment of the two members of said positive working model.

An indirect bonding tray places orthodontic appliances in precise, predetermined positions on the teeth of a patient. The indirect bonding tray includes a first matrix material that extends over a set of appliances and a second matrix material that extends over the first matrix material. The indirect bonding tray also includes at least one occlusal stop member that is connected to the second matrix material for firm, relatively hard contact with the occlusal tips of the patient's teeth when the tray is received in place over the patient's dental arch.
摘要:
A computer-implemented method for generating a digital model of an individual intraoral component from a digital model of a patient's dentition obtains a 3-D digital mesh model of the patient's dentition and performs automatic tooth component segmentation operation on the obtained mesh model. Automated segmentation results display. Interactive segmentation of the automated segmentation results is performed according to an operator instruction. Segmentation results are displayed and stored.
摘要:
Compositions comprising one or more chelating agents and optionally zinc ion salts are used to inhibit the growth or biofilm formation in bacteria associated with personal care products such as ophthalmic, pedicure, manicure or podiatric solutions. The compositions of the present application can also comprise gelling agents, antimicrobials, antibiotic or a pH adjuster. The compositions may be in the form of a solution, a gel, a cream, a jelly, a powder, a paste, a lotion, soap and a cleaner.
摘要:
Disclosed is a method for scanning an edentulous patent who has a denture, where an impression material arranged at the gum-facing surfaces of the dentures is shaped by the patient's gums and both the teeth side and the gum-facing surface of the denture is scanned and the obtained digital 3D representations are used to determine the relative arrangement of the patient's edentulous jaws in a bite determined by the dentures.
摘要:
Articulator—semiadjustable, arcon with lower and upper parts that could be detached from one another or interconnected, with two mechanical joints. An upper horizontal shoulder (5) is fixed to an elevator (4), said elevator (4) is connected to an upper vertical body (11) and can move vertically to adjust the vertical position. A lower vertical body (10) is fixed to the base (1) and holds an axis with two joint heads (14). The upper vertical body (11) is pivotably connected to the lower vertical body (10) through the two joint heads (14), the distance between the joint heads can vary due to an elastic element (18), thus reproducing the lateral shift. The articulation between the vertical bodies (11 and 10) can be locked and unlocked via an elbow shaped piece (13). The articulator lower part has an incisive platform (8) with a position angle that could be adapted.
摘要:
Disclosed is a method for determining the relative arrangement of patient's jaws in a bite position when the patient's occlusion is not defined by natural teeth alone, where the method comprises a step of obtaining a digital 3D representation comprising both surface data relating to dental tissue in one of the patient's jaws and surface data relating to a scan appliance arranged in relation to the jaw, where the scan appliance is configured for at least partly defining the patient's occlusion.
摘要:
An apparatus for implanting a tooth implant in a patient, comprising an attachment element (200) that comprises a precise-tooth-shape-retaining material (234), the precise-tooth-shape-retaining material (234) suitable for molding and hardening into a rigid state and useful for exclusively chair-side configuring of at least a portion of the attachment element to match said patient's teeth, the attachment element (200) also configured for coupling to a patient tracking device (270) and for receipt of either at least one fiducial marker (206) or a fiducial carrier (202) that carries the at least one fiducial marker (206), wherein said attachment element (200) is configured to be removably and replaceably attachable to said patient's teeth at a precisely repeatable position with respect to said patient's teeth such that whenever said attachment element (200) is remounted onto said teeth, the fiducial carrier (202) or at least one fiducial marker (206) regains a same spatial position relative to the patient's teeth or jaw bone.
