Patent number: 8682043Abstract: A method of obtaining and merging volumetric data and surface data of a patient's dentition for use in designing and/or manufacturing a prosthodontic component, such as a drill guide, an implant, or other prosthodontic appliance, for example. A plurality of radio-opaque markers are temporarily secured directly to a patient's dentition. Surface data is then obtained, such as by scanning the patient's dentition with the markers or alternatively, by taking an impression of the patient's dentition with the markers, forming a physical model that includes analogs of the markers, and scanning the physical model. Either before or after the surface data is obtained, an anatomical, volumetric image data set of the patient's dentition is obtained via a volumetric scan of the patient's dentition with the markers appearing in the image data set.Type: GrantFiled: February 26, 2009Date of Patent: March 25, 2014Assignee: Zimmer Dental, Inc.Inventors: Sean B. Cahill, Shaun (Shahram) Zamani, Suneel Ranga Sai Battula, Steve T. Pelote

Patent number: 8662900Abstract: A bone implant surgery system is used for simulating a dental surgical procedure having a display that shows placing a simulated bone implant at a simulated implant site on a living body by using a simulated surgical tool holding the simulated bone implant. At least one hand-held haptic device is used to control the surgical tool and at least one controller is specifically configured to cause movement of the surgical tool on the display based on motions of the haptic device and to cause haptic feedback to a user holding the haptic device depending on the position of the surgical tool on the display. A user may then review and evaluate the results of the surgical simulation.Type: GrantFiled: May 28, 2010Date of Patent: March 4, 2014Assignee: Zimmer Dental Inc.Inventors: Fred Albert Bell, III, Jeffrey A. Bassett, Michael Collins

Publication number: 20130224683Abstract: A dental drill is disclosed which allows for an osteotomy to be formed in a shape which closely matches the cylindrical shape of many dental implants. In so doing, the implant engages more tissue of the resulting osteotomy, thus resulting in greater ability for the tissue to penetrate and fuse with the implant while also reducing the chances of infection and reducing the overall recovery time. In addition, by forming the dental drill with a relatively obtuse angulation between the termini of the drill flutes, the cutting forces are spread across a larger cutting area thus reducing wear on the drill itself. Moreover, by spreading the cutting force over a larger area, the heat generated by the drill is reduced and thus the discomfort afforded to the patient is reduced.Type: ApplicationFiled: February 23, 2012Publication date: August 29, 2013Applicant: ZIMMER DENTAL, INC.Inventors: John R. Zacharia, Kim Nguyen

Publication number: 20130209957Abstract: A ceramic and metallic dental abutment for use with a dental implant is disclosed. The abutment can generally include a body having a base region, a coronal region, and a transgingival region disposed between the base and coronal regions. The body regions can define a longitudinal axis. The base region can include an anti-rotational feature such that, when engaged with the dental implant, an anti-rotational connection exists. The coronal and transgingival regions can include a ceramic exterior surface. The abutment can further include a metal contact portion having an annular shape and positioned to engage the dental implant. The metal contact portion can include a conical outer contact surface, disposed at an oblique angle with respect to the longitudinal axis, to match an angle of a chamfer of the dental implant.Type: ApplicationFiled: March 26, 2013Publication date: August 15, 2013Applicant: Zimmer Dental, Inc.Inventor: Zimmer Dental, Inc.
