Patent number: 11571282Abstract: A pontic device for preserving soft tissue in a tooth-extraction site includes a generally curved apical end. The apical end has a first perimeter and is configured to rest in a tooth extraction socket and substantially conform to soft tissue of a tooth-extraction site immediately after a tooth has been extracted. The pontic device further includes an opposing, generally concave coronal end. The coronal end has a second perimeter that is configured to substantially correspond to and form a seal with gingival tissue surrounding the tooth-extraction site. The coronal end is configured to receive a tooth-shaped coronal pontic portion to form a final restoration.Type: GrantFiled: October 18, 2019Date of Patent: February 7, 2023Assignee: Keystone Dental, Inc.Inventors: Stephen J.

Patent number: 7887325Abstract: Disclosed are an implant-driver assembly and an associated method. Generally, the implant-driver assembly includes a driver, an implant and a coupler that affixes the implant to the driver during transport and during insertion of the implant into the jaw of a patient. As shipped, the assembly may take the form of a superassembly with a vial insert that impedes axial movement of the driver, coupler, and implant. Via manual action or assisted with a suitable tool, the coupler may be disengaged to thereby decouple the implant and driver once the implant has been properly positioned. Also disclosed is a method for inserting an implant, the method comprising applying torque to the driver of an implant-driver assembly as disclosed herein.Type: GrantFiled: April 4, 2008Date of Patent: February 15, 2011Assignee: Keystone Dental, Inc.Inventor: Dale Whipple

Publication number: 20100086900Abstract: Disclosed is a kit useful in connection with the preparation of dental prostheses and including an implant-abutment analogue and a burnout coping. The analogue generally corresponds to an implant and abutment in the jaw of a patient. A burnout coping is secured to the analogue for the preparation of the dental prosthetic. In one embodiment, the analogue includes a connection feature and the coping includes a mating connection feature, the connection feature on the coping positioned to provide a remnant on the dental prosthetic prepared thereform that does not interfere with the placement of the prosthetic onto an implant and abutment in the jaw of a patient. In another embodiment, not mutually exclusive with respect to the first embodiment, the coping comprises first and second portions that are movable with respect to one another and sized respectively to engage first and second portions of an analogue.Type: ApplicationFiled: May 6, 2009Publication date: April 8, 2010Applicant: Keystone Dental, Inc.Inventor: Dale Whipple
