Abstract: A method of whitening teeth that decreases the amount of time that the whitening composition is in contact with the teeth. Specifically, by pretreating the whitening composition with light before contacting the teeth with the whitening composition, the amount of time that the whitening composition needs to be in contact with the teeth can be reduced. In one aspect, the method may include dispensing a tooth whitening composition from a reservoir device into a channel of a mouth tray; activating an electromagnetic radiation source to emit light onto the tooth whitening composition in the channel of the mouth tray for a first period of time to pretreat the tooth whitening composition; and inserting the mouth tray into the oral cavity of the user so that the user's teeth are in contact with the tooth whitening composition in the channel for a second period of time to whiten the teeth.

Abstract: An intraosseous dental implant for the application of biologically active agents directly to the surrounding soft tissues and bone tissue, and their substitutes, is described. The implant enables the measurement of the newly formed or lost bone tissue volume immediately adjacent to the implant. Increasing the dynamics of osseointegration growth directly results in the possibility of reducing the duration of the entire treatment protocol. To increase dynamics of the osseointegration process, the type of material from which the implant is made, its design features, surface topography, as well as the formation of layered structures and coating applications, are described. The implant introduces growth factors and other biologically active factors that affect an increase in the dynamics of osseointegration strength.

Abstract: An elongated member is used to create tension to move teeth en masse to correct Class II and Class III malocclusions. The elongated member has a constant force spring that, when stretched, provides tension along the elongated member. A mesial end of the elongated member is attached to a bridge assembly which is attached to a row of teeth, and a distal end of the elongated member is attached to an anchor. The spring member provides a constant tension which moves the bridge assembly, and hence the row of teeth, a precalibrated distance.

Abstract: Systems and methods for monitoring a patient's teeth during orthodontic treatment, which may include the use of a series of appliances according to a corresponding series of treatment stages. The system may include a device in communication with one or more sensors of a first appliance implementing a particular treatment stage. The device may be configured to receive monitoring data corresponding to sensor data captured at the one or more sensors, where the sensor data is associated with at least one parameter related to a change in position or movement of the teeth. The device may further be configured to predict tooth positions or movements based on the sensor data, and compare the predicted tooth positions or movements to expected tooth positions or movements. The device may additionally be configured to determine that the first appliance should be replaced with a second appliance based on the comparison.

Abstract: Orthodontic aligners can be used to help shape a patient's teeth, jaw, and gums. Aligners are designed to move teeth into a desired position. Prior to the treatment, a dental professional will prepare a treatment plan (e.g., a set of aligners, etc.) Each aligner in the set may perform a different action on different subsets of teeth. Many dental professionals use animation software to show the patient an animation/video of the changes that are going to occur to the patient's teeth/jaw over time as a result of the treatment plan. While the animation may visually depict how the teeth and mouth are going to change, it does not tell the patient what is being performed (i.e., the actions that are being taken to move the teeth). As a result, the patient often has a significant number of questions because they are not properly educated on the treatment.
