The method of manual preparation for dental implantation using the manual driver has a high precision, and reduces the risk of bone cracking caused by vibration of motor-driven drilling. The manual drilling method provides better tactile sensation and drilling control to the dentist. Further, the method avoids drilling irrigation, allows collection of virgin bone tissue from the drills, and reintroduces the collected bone tissue in the receiving bore to promote bone regeneration after the implantation.Type: GrantFiled: January 25, 2007Date of Patent: November 3, 2009Inventor: German L.

Patent number: 7556500Abstract: Bone-adaptive surface structures are provided for lateral jaw implants. Micromechanical and/or macromechanical surface structures having various body forms are incorporated into selected segments of the surface of a base and of a bar that connects a shaft with the base to accelerate the healing process after the implant is inserted into the jaw bone and to make a critical improvement in holding the implant firmly in place without rotation. A process of manufacturing the surface structures includes forming a macromechanical surface on the implant to increase its surface area; and superimposing micromechanical canals on the macromechanical surface, the canals having a size smaller than the minimum size of the osteons in the bone into which the implant is to be inserted.Type: GrantFiled: December 17, 2004Date of Patent: July 7, 2009Assignee: Biomed Est.Inventor: Stefan Ihde

Patent number: 7530810Abstract: A dental implantation system is for securing a dental prosthesis in a patient's jawbone including an alveolar bone, a basal bone adjacent the alveolar bone, and a neurovascular bundle running through the jawbone. The dental implantation system may include a dental implant fixture having an elongate shape and including an upper portion to be positioned in the alveolar bone to receive the dental prosthesis and defining a first axis. The dental implant fixture may also include a lower portion to be positioned in the basal bone and defining a second axis. The dental implant fixture may further include an intermediate offset-defining portion between the upper portion and the lower portion to define an offset between the first axis and the second axis so that the lower portion avoids the neurovascular bundle.Type: GrantFiled: August 30, 2006Date of Patent: May 12, 2009Inventor: Milton A. Clement

Patent number: 7287983Abstract: The present invention relates to a polymeric implant, especially useful for dental medicine. More specifically, the present invention relates to a polymerizable device comprising an artificial tooth's root and an abutment anchored therein and to a kit comprising interalia the same. The present invention also relates to a method for implanting the implant in the alveolar bore of previously extracted tooth.Type: GrantFiled: April 21, 2002Date of Patent: October 30, 2007Assignee: Polydent Medical Devices Ltd.Inventor: Daniel Ilan

Patent number: 7214063Abstract: An implant system includes: an implant for implanting into a bone; an abutment to serve as a support for fixing a prosthesis to the bone; and a pivotal coupling between the implant and the abutment to permit, after the implant has been implanted into the bone, precise angulation in all directions of the abutment with respect to the implant before the abutment is fixed at the desired precise angulation with respect to the implant. Preferably, the pivotal coupling includes a ball-and-socket having complementary shaped contacting surfaces which are uneven to temporarily hold them in a direct pivoted position before permanently fixing them.Type: GrantFiled: July 1, 2005Date of Patent: May 8, 2007Inventor: Yechiel Cohen

Patent number: 7179089Abstract: An abutment system for a dental implant includes an abutment having a base portion that is engageable with a dental implant and a shoulder disposed about the base portion that includes a hybrid ceramic material. The hybrid ceramic material includes at least 85% porcelain. An opaque can be applied to the exterior surface of the abutment. A pigment can also be added to the hybrid ceramic material so as to match the color of the patient's gum tissue. A method of preparing an abutment system includes the steps of forming a curable hybrid ceramic material into a shoulder about the base portion of an abutment, partially curing the hybrid ceramic material so as to form an initially cured shoulder, shaping the initially cured shoulder to a desired shape so that the shoulder conforms to at least one patient specific criterion, and completely curing the shoulder. A plurality of abutment systems may be assembled into a kit.Type: GrantFiled: October 20, 2003Date of Patent: February 20, 2007Assignee: Prosthosolve, LLCInventors: Lawrence O. Sims, Brian K. Lindke, Yuichi Ikenaga

Patent number: 7090494Abstract: An implant includes an implantable body portion adapted to be at least partially recessed within a patient's alveolar bone, and which has a peripheral surface portion, which is configured to stimulate and/or facilitate the engagement of osteoblasts and other bone tissues with the implant. The implant body provides bone engaging regions along one or more of the distal and/or mesial implant surfaces, which are elongated relative to bone engaging regions on the lingual and/or buccal surfaces of the implant body. In particular, the implantable portion of the implant body includes a bone engaging surface which, when the implant body is fully seated within the patient's jaw bone, extends from a distal portion of the implant body to a remote proximal-most edge. The proximal-most edge has a contour selected to generally follow a predetermined crestal outline of the supporting bone tissue.Type: GrantFiled: January 8, 2004Date of Patent: August 15, 2006Assignee: Innova Corp.Inventors: Avi Shelemay, Mike Kehoe

Patent number: 6343931Abstract: Plugs for use in sinus lift and augmentation techniques have a mushroom-like shape and having of a substantially cone-shaped body with an integral head of enlarged diameter. The plugs are preferably formed of donor cadaver bone, osteosite or hatogens. The plugs, in one embodiment, are formed of universal sizes and are preferably “CAD CAM” cut, based on a scan of the orifice. The plugs have a fluted or corrugated-like periphery and are preferably swaged into a previously prepared cavity, the fluted configuration preventing rotation of the plug. An implant is then counter-sunk into the core plug. The core plugs, once in place, promote bone growth and integration as self to enhance and provide a bed of rich bone in compromised and deficient areas structurally and esthetically. A set of tapped drills range from 2.8 mm up to 7.5 mm in diameter and lengths of 8 mm-15 mm can be used and standard plugs can be used in place of CAD CAM (i.e., “custom”) cutting.Type: GrantFiled: September 9, 1999Date of Patent: February 5, 2002Inventor: Gerald J.
