Abstract: Provided herein are processes for the generation of composite polymer materials utilizing a single resin. The processes utilize diffusion between a region undergoing a polymerization reaction preferentially polymerizing one monomer component and an unreactive region. Diffusion and subsequent/concurrent polymerization results in a higher concentration of the more reactive monomer component in the reacting region and a higher concentration of the less reactive monomer components in the unreactive region. The unreactive region may be later polymerized. In embodiments, photopolymerization is used and the regions are generated by a mask or other mechanism to pattern the light.

Abstract: A shell removal device includes a platform configured to secure a mold. An untrimmed shell is formed over the mold. The shell removal device further includes a drive mechanism configured to move the platform away from the untrimmed shell responsive to sensor data indicative that the untrimmed shell has begun to separate from the mold.

Abstract: Creating a digital tooth model of a patient's tooth using interproximal information is provided. Interproximal information is received that represents a space between adjacent physical teeth of the patient. A digital teeth model of a set of physical teeth of the patient that includes the adjacent physical teeth is received. One or more digital tooth models is created that more accurately depicts one or more of the physical teeth than the corresponding digital teeth included in the digital teeth model based on the interproximal information.

Abstract: A dental template for positioning an object on teeth of a patient and method for fabricating the same. The method includes creating a digital model of the patient's teeth, creating a simplified template model based on the digital model, and fabricating the dental template based on the simplified template model. The template model is simplified by removing certain features of the patient's tooth anatomy. The dental template can be located on a patient's teeth using four or fewer positioning teeth.

Abstract: A method for preparing for and providing dental treatment may include determining, by an action management system, that 3D scan data of a patient's dentition has been received by a treatment planning system. A treatment planning system may generate a treatment plan to move the patient's teeth from an initial position towards a final position, based on the 3D scan of the patient's dentition. The treatment plan may be provided to a dental professional system. The action management system my generate an object for display on the dental professional system indicating that the treatment plan has been provided. An indication that the treatment plan is approved for fabrication may be received, and instructions to fabricate a dental appliance based on the treatment plan may be sent.

Abstract: A scanner for scanning a dental site comprises a base, a detector mounted to the base, and an optical element to redirect light reflected off of the dental site towards the detector along a detection axis in a first direction. Two or more flexures couple the optical element to the base, wherein thermal expansion or contraction of the optical element with respect to at least one of the detector or the base bends each flexure of the two or more flexures in a respective second direction without bending the flexure in a respective third direction approximately perpendicular to the first direction and the respective second direction, wherein the two or more flexures maintain an alignment of the optical element to the detector with changes in temperature.

Abstract: A method for distinguishing between types of intraoral areas of interest (AOIs) includes receiving or generating a first 3D model comprising teeth; receiving or generating a second 3D model comprising the teeth; comparing the first 3D model to the second 3D model; determining a difference between the first 3D model and the second 3D model at a dental site comprising a tooth; determining an intraoral AOI that is associated with the difference; determining whether the difference comprises a first type of change indicative of a first type of intraoral AOI or a second type of change indicative of a second type of intraoral AOI; and responsive to determining that the difference comprises the first type of change, determining that the intraoral AOI is the first type of intraoral AOI and generating an indicator of the first type of intraoral AOI for the tooth.
