  • Publication number: 20240252281
    Abstract: The invention relates to a computer-implemented method for determining parameters of one or more ortho-restorative measures to be applied to a tooth. The one or more ortho-restorative measures comprise an orthodontic adjustment of a position of the tooth within a dentition. The method comprises a receiving of a three-dimensional digital tooth model, a receiving of a three-dimensional digital restorative tooth model, a determining of a three-dimensional digital reduced restorative tooth model a determining of a core section of the three-dimensional digital tooth model to be excluded from preparation, a determining of one or more orthodontic parameters descriptive of the orthodontic adjustment of the position of the three-dimensional digital tooth model with at least a part of the core section of the orthodontically adjusted three-dimensional digital tooth model fitting into the three-dimensional digital reduced restorative tooth model, an outputting of the one or more orthodontic parameters.

  • Publication number: 20240252282
    Abstract: Methods and systems for determining a dental treatment difficulty in digital treatment planning. The methods may include determining changes in position of first and second teeth between initial and target dental models relative to an arch line of the initial dental model of a patient's dentition. The changes in position may be determined by projecting first and second distances between initial and subsequent positions of the teeth onto the arch line. A treatment difficulty of anterior-posterior correction may be determined by comparing a calculated average change in position to one or more threshold changes in position. The digital treatment plan may be adjusted when the average change in position is greater than at least one of the one or more threshold changes in position.

  • Publication number: 20240252283
    Abstract: A retainer for orthodontic treatment comprises one or more double wings, each double wings consisting of a center piece and two wings adjoining the center piece laterally, the wings are formed areally and each have a front side and a rear side, the front side being formed for surface bonding to the lateral surface of a tooth and the center piece firmly connecting the wings adjoining it to one another. The retainer allows for individualized adaptation without detaching the entire retainer for bonding renewal or in case of damage or loss of a double wing. An electronic image of the tooth row contour is utilized for customized producing the retainer by using 3D printing or milling.

  • Publication number: 20240252284
    Abstract: Disclosed are apparatuses and techniques for distalizing, mesializing and/or expanding teeth in the upper or lower dental arch of a patient's mouth to make room for crowded or protruded teeth located in the anterior arch region to distally/mesially and/or laterally shift into. In some aspects, an apparatus includes a body; a first arm coupled to an adjustment mechanism of the body and attachable to a molar; a second arm coupled to the apparatus body and attachable to a non-molar tooth; and an anchorage device attachable to a bone in the mouth, which the first arm is configured to transfer a force onto the molar when the adjustment mechanism is actuated to cause movement of the molar in the dental arch, and which the anchorage device is operable to positionally stabilize the body and the second arm to prevent movement of the non-molar tooth in the dental arch.

  • Publication number: 20240252287
    Abstract: An improved preparation method uses an additional preparation tray as part of a multi-step tray alignment system which achieves orthodontic tooth movement. The preparation tray incorporates openings in the tray for the application of a bonding preparation fluid, such as an etching agent, or alternately, an etching and bonding agent, in the correct location and amount. The openings are at least the size and shape of the tooth attachments and greatly reduce the tooth surface area accessible to the clinician. This confines the bonding preparation fluid to an area equal to, or slightly larger than, the attachment contact area. The method and apparatus provide faster application, vastly reduced cleanup, less tooth enamel damage, and less chair time for the patient.
