Patent number: 8858228Abstract: Method and kit for producing implant drilling guides positioned at the proper orientation to avoid inadvertent damage to critical regions of the patient's jaw when drilling to place dental implant screws. The method works by placing a small post device with x-ray visible depth markers in the root socket of the patient's tooth immediately after tooth extraction. The post device may additionally be configured to guide the drill at a position and angle that is different from that of the original tooth socket. This post device is used to construct a removable guide that anchors to the patient's adjacent teeth, and preserves the location and orientation of the extracted tooth root. Once the root socket is filled in with new bone, the guide, in conjunction with the X-ray post depth information, can be used to direct drilling along the same route as the old tooth root, thus avoiding critical structures.Type: GrantFiled: March 14, 2012Date of Patent: October 14, 2014Inventor: Howard Ian Katz

Publication number: 20140205965Abstract: Systems and methods are provided for performing a disinfecting treatment. A fluid is placed within a volume, where the fluid absorbs radiation of a first wavelength, and where the fluid is transparent to radiation of a second wavelength. Radiation of the first wavelength is applied near or inside the volume to generate shockwaves or pressure waves in the fluid. Radiation of the second wavelength is applied near or inside the volume to cause thermal disinfection.Type: ApplicationFiled: January 22, 2014Publication date: July 24, 2014Applicant: BIOLASE, Inc.Inventors: Dmitri Boutoussov, Alina Sivriver, Vladimir Netchitailo

Publication number: 20140205968Abstract: A dental cutting system for cutting a patient's tooth comprises a cutting guide with a slot to guide a cutting tool. Opposing channels are formed in opposing walls of the slot. A sleeve is slidably disposed in the slot and has an enlarged collar slidably disposed in the opposing channels. The enlarged collar retains the sleeve in the slot with respect to an in-and-out direction and limits the sleeve to movement within and along the slot. The sleeve has a bore removably receiving the cutting tool, with the cutting tool being rotatable in the bore and slidable through the bore in the in-and-out direction, and into and out of the sleeve. The cutting tool has two transverse degrees of freedom, including laterally along the slot, and in and out of the slot and the sleeve.Type: ApplicationFiled: January 17, 2014Publication date: July 24, 2014Applicant: DigitalPrep Technologies, Inc.Inventors: Daniel Yonil Jung, Yunoh Jung

Patent number: 8784106Abstract: A dental preparation delivery system includes a soft malleable wax sealing strip bonded to a wax base strip. The peripheral outline of a model dentition extends into the thickness of the sealing strip to form a receptacle. A border of the sealing strip completely surrounds the outline. The receptacle is filled with a dental preparation to be administered and the sealing strip is overlaid with a film. In use, the film is removed, the system is bent to an arch shape and the outline is registered with the user's buccal dentition. Lateral force is applied in a lingual direction against the base strip to reshape the sealing strip for sealing contact of the border against the periphery of the user's buccal dentition, while leaving the preparation in contact with remaining buccal surfaces.Type: GrantFiled: August 26, 2013Date of Patent: July 22, 2014Inventor: Eugene C. Wagner

Publication number: 20140199653Abstract: In an exemplary embodiment, a method of creating an impression of structures of the human oral cavity comprises: preparing impression trays; creating a first, or base, impression; grinding out portions of the base impression; and using the void(s) in the ground out base impression to take a second, or wash, impression. The base impression is taken with an excess of a high-density impression material which is positioned to extend beyond the structures of interest (of which the impression is being taken). The base impression is removed and all fine structure surrounding the structure(s) of interest is ground out. A wash impression is then taken using a low-density impression material. The base impression creates a seal around the structure(s) of interest (a closed system), thereby producing omnidirectional hydraulic pressure on the low-density material. Such omnidirectional hydraulic pressure produces a highly detailed final impression from which a high-quality model (e.g., cast) can be made.Type: ApplicationFiled: January 15, 2014Publication date: July 17, 2014Applicant: Evolve Dental Technologies, Inc.Inventor: Rodger Kurthy
