Abstract: An obturation apparatus for prepared root canals incorporates the functionality of an endodontic spreader but with a circular disk located at a fixed distance from a distal tip of the apparatus and regulates the length of bioceramic putty inserted into the prepared root canal. The instrument comes in various sizes to cater to prepared root canals of differing dimensions such that the apparatus must be prefit before the application of the bioceramic putty to the apparatus tip before extending the bioceramic putty to the distal side of the circular disk. The apparatus is then inserted to a desired depth with application of apical pressure leaving the bioceramic putty in place as an apical plug when the apparatus is removed.

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: An endodontic handpiece comprises a handle assembly and an endodontic tool. The handle assembly comprises a handle housing, a chuck assembly, a bearing system for supporting the chuck assembly for rotation relative to the handle housing, a first drive system for rotating the chuck assembly, and first and second drive systems. The endodontic tool defines a support portion and a working portion. The chuck assembly transfers movement of the chuck assembly to the endodontic tool. The endodontic handpiece operates in at least one of first, second, and third modes in which the first drive system causes rotation of the endodontic tool through the chuck assembly, the second drive system causes vibration of the endodontic tool, and/or the first drive system causes rotation of the endodontic tool through the chuck assembly.
