Patent number: 9333054Abstract: The invention is for the repair of a traditional implant previously installed, the implant being of the kind currently manufactured by many implant companies. The invention includes a method and apparatus used to repair a diseased tooth implant having peri-implantitis. A soft thin titanium alloy sleeve having an exterior treated surface for enhancing osseo-integration is used for implant surface restoration. The sleeve is initially installed on a dowel. The dowel is necessary to support the thin soft deformable sleeve at all times to prevent its collapse or being crushed. The dowel is also necessary to accomplish the transfer of the sleeve onto the implant surface. The diseased implant is restored by a new surface that enhances osseo-integration provided by the surface restoration sleeve.Type: GrantFiled: January 23, 2014Date of Patent: May 10, 2016Inventor: Leonard M.

The denture base has an oversize cutout and a corresponding cavity and the support bar has a plurality of reference posts which mechanically interface with the corresponding cavity so that the support bar is connected to the artificial denture base and provides reinforcement and stability to the denture system. The shape and position of the reference posts fully constrains the support bar in a fixed position with reference to the denture base. In one embodiment, the denture base snap-fits onto the support bar.Type: GrantFiled: August 29, 2013Date of Patent: June 16, 2015Assignee: Global Dental Science LLCInventors: Johannes Petrus Michael Grobbee, Jerry Gaubert

Publication number: 20150147720Abstract: The present invention relates to a tooth-replacement implant, comprising: a main body portion and a root cervical portion, wherein the root body portion has a plurality of lateral pores and a hollow thorough hole at the bottom. Further, a collagen coating layer and an anti-bacterial coating layer are formed on the surface of the body portion root. Therefore, the present invention may increase bone contact area and enhance stability, and thereby avoiding compressing nerve to cause paralysis of perception through the implant and avoiding the sinus perforation.Type: ApplicationFiled: June 30, 2014Publication date: May 28, 2015Inventors: Wen-Fu LAI, Chien-Chou LIN, Mao-Suan HUANG, Wu-Hsiung LIN

Patent number: 9039415Abstract: Connecting screw (22) for a dental implant (18) can be screwed securely by means of a commercially available rotary tool (24), even if the central longitudinal axis C of the connecting screw (22) and the longitudinal axis D of the rotary tool (24) are arranged at an acute angle to one another. For this purpose, the connecting screw (22) has a shaft portion (32) having an outer thread (48) for connection to the dental implant (18), and a head portion (34) having a blind-bore-shaped recess (36), which is open toward the upper screw end (46) and in which an engagement means (50) for the rotary tool (24) is formed integrally.Type: GrantFiled: November 26, 2012Date of Patent: May 26, 2015Assignee: Straumann Holding AGInventors: Patrick Streff, Edmund Suter

Publication number: 20150140509Abstract: There is provided a dental implant which can prevent peri-implantitis and in which an affinity of a jawbone embedded portion embedded into the jawbone with the jawbone is not degraded. In a dental implant, at least a region of a gingiva contacting portion which is in contact with gingiva, is antibacterially treated, and an arithmetic average roughness Ra of an outer surface of the region is set to 2 ?m or less. At least the region of the gingiva contacting portion has antibacterial properties, and becomes such a surface texture that bacteria are less prone to attach to and stay in the region, and the region is prone to be in close contact with the gingiva.Type: ApplicationFiled: May 30, 2013Publication date: May 21, 2015Applicant: KYOCERA Medical CorporationInventors: Yuji Nakano, Noriyuki Ishida

Publication number: 20150140507Abstract: Drilling of an implant shaft is carried out with a handpiece tool whose location and angular orientation with respect to a radiographic working guide is updated in real time with respect to the radiographic working guide and anatomical structures of the patient, free of viewing obstructions. Prior to the drilling, the radiographic working guide is fitted to a particular patient. Real-time imaging support is provided on a display of a computer, wherein the radiographic workpiece guide includes a plurality of fiducial markers that define a substantially planar reference surface of the radiographic workpiece guide. The radiographic workpiece guide also includes an alignment structure located a predetermined distance from a pilot hole proximate the work site. The image is updated based on an initial radiographic scan and updated position information from the handpiece tool as to location and angular orientation of the handpiece tool relative to the workpiece guide.Type: ApplicationFiled: November 20, 2014Publication date: May 21, 2015Inventors: Allen M. Moffson, Majid Azmoon

Patent number: 9033709Abstract: A dental attachment assembly and method anchors a dental appliance with an implant and has an abutment member attached to the implant, a retention member in releasable snap engagement with the abutment member, and a cap secured in a recess of the dental appliance and in releasable swivel engagement with the retention member to position and secure the dental appliance onto the implant. The cap includes a cavity with a rounded, concave inner surface which engages with the retention member, an interior top surface of the cavity with a concave recess extending radially along an outer periphery of the interior top surface of the cavity to allow for rotation of the retention member within the cap. A central portion of the interior top surface of the cavity surrounded by the concave recess therefore protrudes vertically into the cavity to minimize vertical displacement of the retention member as it rotates.Type: GrantFiled: June 6, 2014Date of Patent: May 19, 2015Assignee: ZEST IP HOLDINGS, LLCInventors: Richard Robert Allen, Christopher Michael Gervais

Patent number: 9034201Abstract: A method of forming an implant to be implanted into living bone is disclosed. The method comprises the act of roughening at least a portion of the implant surface to produce a microscale roughened surface. The method further comprises the act of immersing the microscale roughened surface into a solution containing hydrogen peroxide and a basic solution to produce a nanoscale roughened surface consisting of nanopitting superimposed on the microscale roughened surface. The nanoscale roughened surface has a property that promotes osseointegration.Type: GrantFiled: October 9, 2013Date of Patent: May 19, 2015Assignee: Biomet 3i, LLCInventors: Robert L. Mayfield, Ross W. Towse

Patent number: 9033708Abstract: A dental bridge armature designed to be screw-fastened onto dental implants, the dental bridge armature having reinforcing elements formed by long fibers pre-impregnated with photo-polymerizable resin which are either woven or in bundles. The reinforcing elements are in the form of a fibrous framework including a main brace and base reinforcing elements wound around a series of implant abutments screwed onto the implants. Secondary braces are also wound around the main brace and the base reinforcing elements. The braces form an angle between 15° and 85° with the base reinforcing elements. The armature is then included in a PMMA coating resin by a pressing or injection technique.Type: GrantFiled: March 25, 2013Date of Patent: May 19, 2015Inventors: Bruno Clunet-Coste, Bernard Maneuf, Andre Collombin, Raymond Monette

Patent number: 9028253Abstract: A surgical method and tool for expanding an initial osteotomy (42) to receive a bone implant (44). An osteotome (22) having a tapered working end (28) is inserted into the initial osteotomy (42). The initial osteotomy (42) is enlarged by simultaneously rotating and pushing the working end (28) of the tapered osteotome (22) into the osteotomy (42). When rotated in one direction the burnishing edges (40) concentrate the pushing and rotational force in outward normal and tangential component forces against the interior surface of the osteotomy (42) to incrementally expand the osteotomy (42) with little to no removal of bone material (46). When rotated in the opposite direction the burnishing edges cut the interior surface of the osteotomy. Progressively larger tapered osteotomes (22) are used until an osteotomy (42) of predetermined size is achieved.Type: GrantFiled: September 10, 2012Date of Patent: May 12, 2015Assignee: Huwais IP Holding LLCInventor: Salah Huwais
