The present disclosure features adhesive compositions and methods of use thereof related to the medical, veterinary, and dental fields.

An intraoral scanning system for scanning an intraoral dental structure of a patient in a dental procedure may include an intraoral scanner and one or more processors coupled to the intraoral scanner and programmed with instructions that when executed by the one or more processors cause the intraoral scanning system to build a 3D model of the intraoral dental structure of the patient based on scan data acquired via the intraoral scanner and output feedback on a display. The feedback may include highlighting a portion of the 3D model that includes scan data that includes a finish line of the intraoral dental structure, wherein the scan indicates that the finish line is not suitable for receiving a prosthetic.

Feedback data useful in prosthodontic procedures associated with the intra oral cavity is provided. First, a 3D numerical model of the target zone in the intra oral cavity is provided, and this is manipulated so as to extract particular data that may be useful in a particular procedure, for example data relating to the finish line or to the shape and size of a preparation. The relationship between this data and the procedure is then determined, for example the clearance between the preparation and the intended crown. Feedback data, indicative of this relationship, is then generated, for example whether the preparation geometry is adequate for the particular type of prosthesis.

Radically polymerizable dental material, which includes a combination of a hydroperoxide and a thiourea derivative according to the following Formula (I) as initiator system for the radical polymerization:

##STR00001##

in which R is absent or is an (n+1)-valent, aromatic, aliphatic, linear or branched C.sub.1-C.sub.50 hydrocarbon radical, which can be interrupted by one or more ether, thioether, ester, amide or urethane groups; PG is a radically polymerizable (meth)acrylate, (meth)acrylamide or vinyl group; and n is 1, 2 or 3.

Embodiments of the present invention provide devices (tags), systems, and methods to determine structural integrity and other states of materials-of-interest, such as dental fillings, implants, and root canal posts, to name a few, in a non-invasive and contactless way; and using comparatively safe and/or low energy electromagnetic radiation, such as radio waves. Negligible-sized backscatter-tags with sensors are implanted in such materials-of-interest. Using backscatter imaging technology, the structural integrity and other states of the materials-of-interest may be monitored; which may allow non-invasive and contactless detection of problems such as cracking, bending, excessive pressure, improper temperature, and/or the like. Additionally, initially unknown locations of the implanted negligible-sized backscatter-tags with sensors may be readily determined upon a given scanning (reading) session; and thus mapped to provide an effective image of the material-of-interest.
