20080241793 | Dental Implant With Improved Osseointegration Features - Dental implants made at least in part of a highly porous biomaterial such as porous tantalum for enhancing the osseointegration of the dental implant into surrounding bone. For example, there is provided a dental implant which includes a core formed of with a head portion having an abutment interface and a stem portion extending from the head portion. A porous tantalum sleeve is disposed about the stem portion and occupies a substantial portion of the implant/bone interface of the implant. After implantation of the implant, bone tissue may osseointegrate into the porous tantalum sleeve to anchor the implant in position within the surrounding bone. Other embodiments of implants are provided, each implant including at least a portion thereof formed of porous tantalum for improved osseointegration. | 10-02-2008 |
20090011384 | DENTAL IMPLANT FOR A JAW WITH REDUCED BONE VOLUME AND IMPROVED OSSEOINTEGRATION FEATURES - A dental implant has a body with a porous metal portion for engaging bone. The porous metal portion has an outer coronal to apical height and an outer diameter. Both the height and diameter are about 4 mm to about 6 mm. This permits the implant to be placed on a jaw with a reduced bone volume. | 01-08-2009 |
20090061388 | DENTAL PROSTHETIC DEVICE WITH SOFT TISSUE BARRIER PROMOTION MATERIAL - A dental prosthetic device has a body with a soft tissue engagement region formed of porous metal and that defines pores for the ingrowth of soft tissue into the pores. In one form, the porous metal includes tantalum. The porous metal may be partially filled with a resorbable material. The body may have a coronal end portion with an esthetic material. | 03-05-2009 |
20100003638 | MODULAR IMPLANT WITH SECURED POROUS PORTION - A modular implant includes a head, an intermediate part configured to engage bone, and an initially separate anchor configured to engage the head so that at least the head and the anchor cooperatively secure the intermediate part on the implant to form the modular implant. At least one of the head, the intermediate part, and the anchor has a plurality of forms, and each form is configured to be assembled on at least one form of the other two of the head, intermediate part, and anchor. The intermediate part may include a porous metal such as tantalum. | 01-07-2010 |
20100311028 | Dental Implant Surgical Training Simulation System - 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. | 12-09-2010 |
20110008754 | Patient-Specific Implants With Improved Osseointegration - A patient-specific bone implant has a porous body with a core material covered with tantalum. It is made with unique outer dimensions selected to match a specific patient. | 01-13-2011 |
20120214128 | Porous Implant Device for Supporting a Denture - A dental implant device has an implant portion for being placed in a bore in bone. The implant portion has a coronal end portion and a porous metal portion. A metal coupling has a coronal end configured for connection to a denture support piece. The coupling also has an apical end integrally formed with the coronal end and engaging the porous metal portion. In one form, the coupling is attached to the porous metal portion in a threaded connection so that the coupling is removable from the porous portion without significantly damaging the porous metal portion sufficiently to re-engage another metal coupling. | 08-23-2012 |
20120251980 | Method of Forming Patient Specific Implants with Improved Osseointegration - A patient-specific bone implant has a porous body with a core material covered with tantalum. It is made with unique outer dimensions selected to match a specific patient. | 10-04-2012 |
