Patent number: 11273015Abstract: A dental implant for supporting periodontal tissue and the supporting bone is provided. The dental implant includes an implant member with inner canal for insertion into a periodontal bone socket, and an anchoring assembly. The anchoring assembly includes a first fastening element and radially equidistant cylindrical members. The first fastening element engages the implant member within the hollow axial cavity. The root section includes through-holes for radially and forcibly sliding the cylindrical members through them. When the first fastening element apically advances within the hollow axial cavity, the cylindrical members generate an anchoring force to anchor the dental implant.Type: GrantFiled: May 27, 2019Date of Patent: March 15, 2022Assignee: HANKOOKIN, INC.Inventors: James Jiwen Chun, Angela Soyoung Chun, Andrew Youngho Chun, Jennifer Miseong Chun

Patent number: 11253340Abstract: A method of monitoring the degree of fit of an aligner among a series of aligners includes the steps of selecting an aligner in the series of aligners whose fit to a patient's teeth are to be tested to determine its fit with the selected aligner; disposing a nontoxic colored plastic material into the selected aligner; setting the patient's teeth into the selected aligner containing the material; and determining the amount of material disposed onto the interior aligner's surfaces by visual inspection by assessment of the material disposed therein, a good fit being indicated by a minimum of material extruded onto almost all of the interior aligner surfaces and by a light color, and a poor fit being indicated by an excess of material extruded onto one or more locations of the aligner interior surfaces and a dark color.Type: GrantFiled: April 22, 2020Date of Patent: February 22, 2022Inventor: Marc Lemchen

Patent number: 11219510Abstract: The disclosure of the present application relates to a healing abutment system and its use. The abutment system can include a base part adapted to be coupled to a dental implant via an abutment screw and a healing cap that can be coupled to the base part by a further screw. The healing cap can include features that can be scanned by an intra-oral scanning system or transferred to a physical impression to convey information regarding the position and orientation of the base part.Type: GrantFiled: November 18, 2016Date of Patent: January 11, 2022Assignee: Nobel Biocare Services AGInventors: Piers Christiansen, Thomas Vizer, Marco Brunner

Patent number: 11207461Abstract: The present invention provides devices and methods for controlled and continuous delivery of drugs into the brain by bypassing the blood brain barrier, without the need for any surgical manipulation of the brain. The respiratory mucosa in the maxillary sinus or in the nasal region is surgically accessed from the oral or maxillofacial region through a window made on the bone overlying the mucosa. The device is used to deliver drugs in a continuous and controlled manner either beneath or above the respiratory mucosa depending on the clinical requirements, drug formulation and the volume of drug used. The drug distributes into the brain from the delivery site by bypassing the blood brain barrier without causing any significant increase of the drug in the peripheral circulation. The device can be used for continuous and controlled drug delivery into the brain by bypassing the blood brain barrier for a number of medical conditions.Type: GrantFiled: June 9, 2016Date of Patent: December 28, 2021Inventors: Anoop U. R, Kavita Verma

Patent number: 11166792Abstract: A dental implant system including an implant and an abutment is disclosed. The implant includes a generally cylindrical body, a central axis, a distal end for anchoring in a patient's bone and a proximal end opposing the distal end. The proximal end includes a roughened lateralized surface that surrounds an abutment-engaging region. The lateralized surface is disposed at a negative slope relative to the central axis. The abutment includes an upper portion for supporting a tooth-like prosthesis and a lower portion for engaging the abutment-engaging region of the dental implant. The diameter of the lower portion of the abutment is smaller than the diameter of the implant at its proximal end. The lower portion includes a first surface with a soft-tissue enhancing material. The first surface and the lateralized surface defining a circumferentially extending recess having a V-shaped cross-section for receiving and attachment to the soft tissue.Type: GrantFiled: October 9, 2015Date of Patent: November 9, 2021Assignee: Biomet 3I, LLCInventors: Ross W. Towse, Michael D. Scalise, Zachary B. Suttin
