Abstract: Provided herein are methods of obtaining good photocured-ink adhesion to low surface energy materials. The methods have greatly improved adhesion of photocured ink on low surface energy materials, including those that are subjected to high humidity or wet environments. The methods take into account the glass transition temperature (Tg) of the materials and the onset for the glass transition temperature, including ink applied to an exposed surface of the material at an elevated temperature that is close to the Tg of the material. The ink is allowed to sit briefly or soak, such as for more than 1 second, before the ink is cured. The ink may be photocured. Furthermore, the methods do not require solvents or surface treatment, including plasma or corona treatments, to obtain good ink adhesion.

Abstract: A mandibular repositioning apparatus may include anchoring devices shaped for positioning in an intraoral cavity of a patient. Each of the anchoring devices may be configured to be positioned in a respective bone of a respective jaw of the patients. The mandibular repositioning apparatus may include one or more connecting structures configured to displace a lower jaw in an anterior-posterior direction relative to an upper jaw. The one or more connecting structures and the anchoring devices may be configured to be arranged to produce an anterior-posterior force component to move the lower jaw that is greater than a vertical force component.

Abstract: The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include identifying a misaligned jaw of a patient from a virtual image of the patient's jaw, providing a treatment plan for the patient including a virtual model of a dental appliance having a first shell and a second shell configured to reposition at least one tooth of the patient, and adjusting the position of the repositioning jaw elements on the first shell and the second shell to comply with a number of constraints. The virtual model of the dental appliance including repositioning jaw elements on the first shell and the second shell configured to move a position of the misaligned jaw of the patient.

Abstract: The present invention provides orthodontic appliances and systems, and related methods, for applying a force to a target tooth as an appliance is worn by the patient. One positioning appliance includes a tooth positioning appliance having teeth receiving cavities shaped to apply a positioning force to the patient's teeth. The appliance includes a spring-loaded tooth movement device disposed in the appliance so as to engage an attachment mounted on a surface of a patient's tooth and apply a force to the tooth.

Abstract: Embodiments are provided for using an individualized orthodontic treatment index. One method embodiment includes receiving an initial virtual dental model from a first scan of a patient's dentition, modifying the initial virtual dental model to create a target virtual dental model according to a treatment goal, assigning a number of dental references to the target virtual dental model, receiving a treatment outcome virtual dental model from a second scan of the patient's dentition, mapping the number of dental references from the target virtual dental model to a treatment outcome virtual dental model, and calculating an individualized treatment index score for the treatment outcome virtual dental model according to one or more differences between the target virtual dental model and the treatment outcome virtual dental model based on the number of dental references.

Abstract: A dental articulator includes a first arm hingedly joined to a second arm about a pivot axis, where each one of the first arm and the second arm are configured to mount a dental model comprising at least one measurement element, and an inspection tool capable of checking the at least one measurable element against allowable tolerances. Each arm includes a mounting bracket having a distal portion adapted to mount the respective dental model and having a proximal portion. Each arm further has a base member having a distal portion adapted to hingedly join the first arm and the second arm about the pivot axis. The inspection tool comprises a first measurement device and a second measurement device. The first measurement device is coupled to the first arm or second arm and the second measurement device is coupled to the first arm or second arm.

Abstract: Intraoral systems and methods including aligners having soft tissue sensors. The soft tissue sensors may detect protein biomarkers to determine effectiveness of the aligners for causing tooth movement according to a treatment plan. One or more microneedles may be configured to pass the protein biomarker to the soft tissue sensor. A processor may be configured to compare a detected level of the protein biomarker to an expected lever of the protein biomarker, and determine whether an aligner should be replaced. A bias may be configured to apply continuous force to hold the microneedle(s) against a patient's soft tissue. A controller may be configured to apply a biasing force to move the microneedles(s) from a retracted position to an extended position to penetrate the patient's soft tissue.

Abstract: The disclosed computer-implemented method for selecting locations of mandibular relocation features (MRFs) on oral appliances may include determining candidate locations for placing an MRF on a first oral appliance for a first stage of mandibular relocation (MR) treatment and determining candidate locations for placing an MRF on a second oral appliance for a second stage. The method may include selecting from the candidate locations for the first stage and the second stage based on decreasing a distance between the selected pair of candidate locations. The method may further include processing multiple MRFs in parallel. The method may also include increasing a number of initial candidate locations. Locations for intermediate stages may be selected based on interpolating between the first and second stages or based on decreasing a distance between the selected pair if the interpolation fails. The intermediate stages may be processed using a binary search or a linear search.
