Abstract: A 3D virtual model of an intra oral cavity in which at least a part of a finish line of a preparation is obscured is manipulated in virtual space by means of a computer or the like to create, recreate or reconstruct finish line data and other geometrical corresponding to the obscured part. Trimmed virtual models, and trimmed physical models, can then be created utilizing data thus created. The virtual models and/or the physical models may be used in the design and manufacture of copings or of prostheses.

Abstract: Methods and apparatuses for 3D imaging to measure the shape of orthodontic aligners, teeth, and other oral structures simultaneously, in-vivo or in-vitro. These methods and apparatuses may be used to determine contact locations of aligners with teeth and/or teeth with other teeth with very high precision, including determining the size of gaps where they are not in contact. These measurements may be used design, modify or replace an aligner and/or to verify aligner fit. 3D models of the whole aligner and teeth may be generated.

Abstract: Method and Apparatuses for monitoring progress of an orthodontic treatment plan and automatically or semi-automatically modifying the orthodontic treatment plan. The orthodontic treatment plan may be monitored by sensors on one or more appliance in the treatment plan, and may be monitored if the sensed data deviates from the expected treatment plan.

Abstract: Soft tissue (e.g., gingival) sensors for sensing one or more analytes from the soft tissue while being stably held in position against hard tissue, such as the teeth. Described herein are methods and apparatuses for stably holding a soft tissue sensor relative to the teeth so that the soft tissue sensor can sample, including continuously sample. In particular, described herein are methods and apparatuses for holding a sensor having one or more microneedles in position for sampling from the gingiva.

Abstract: A method and system are provided for manufacturing a physical dental model. A virtual model is provided representative of at least a portion of the intra-oral cavity including at least one dental implant implanted therein, and the virtual model includes a virtual portion representative of each dental implant. The virtual spatial disposition of each such virtual portion is determined with respect to the virtual model, corresponding to a real spatial disposition of the respective implant with respect to the intra oral cavity. A physical model is then manufactured based on the virtual model, the physical model including a physical analog corresponding to each implant at a respective physical spatial disposition with respect to the physical model corresponding to the respective virtual spatial disposition of the respective virtual portion with respect to the first virtual model as already determined. In some embodiments, a jig is provided configured for maintaining a desired physical spatial disposition between the physical analog and a cavity of the physical dental model at least until the physical analog is affixed in the cavity.
