摘要： An apparatus includes a template which locates hole positions in a jawbone while the template is separated from the jawbone by gum tissue. The template follows a contour of the gum tissue surrounding the jawbone and has guide holes which receive a cutting tool. Anchoring elements attach the template to the jawbone. A system includes means for scanning an implantation site on a patient's jawbone, simulating the implantation site, and determining nerve-rich areas or nerve paths in the jawbone. A holed template is produced which is separated from the jawbone by at least gum tissue of the patient. Attachment hole positions in the jawbone are located so as to avoid nerve paths. A method of forming holes to attach a dental implant to a patient's jaw bone without surgical intervention in gum tissue of the patient to expose the jawbone is disclosed which avoids impingement on a nerve path.

摘要： The invention relates to components for an improved system for pick-up impression making at a dental implantation site, including an abutment, an abutment replica and an impression coping. The invention also relates to a series of abutments and to a set comprising an abutment and an impression coping. The abutment includes an implant contacting region and a component support region, the component support region has a maximum diameter and extends coronally of the maximum diameter to a coronal end. The component support region also includes a component engagement arranged for releasable engagement with the component by linear displacement of the dental component in relation to the abutment. The component engagement is located at a position closer to the maximum diameter than to the coronal end of the component support region.

摘要： A sinus bolt retention system includes a guide for precisely aligning a sinus support and an implant post for attachment through a bone. The sinus support is a bio-compatible material shaped to closely approximate the internal form of the sinus of the bone. The implant post extends from the outer surface of the bone through a bore hole to engage the sinus support. A denture may be immediately fitted to the implant post.

摘要： An extension piece (2) for a dental implant (1) has a head part (20) which serves as a basis for a retention element (7). The extension piece (2) can be screwed in the dental implant (1) with a threaded stem (29). The extension piece (2) is provided with a reference surface (24) via which the position of the extension piece (2) in the circumferential direction can be transferred to a transfer aid (4) having a transfer surface (42) shaped to complement the reference surface (24). The position of the extension piece (2) is transferred via the transfer aid (4) into an impression (93). The extension piece (2) is then provided with a manipulation implant (5) and is repositioned in the impression (93). From this, a working model (M) is formed in which the desired shape of the extension piece (2) can be defined. The extension piece (2) which has been machined to the desired shape is then screwed into the implant (1) with the same torque as is used for taking the impression.

摘要： A dental prosthesis foundation capable of being finished or adjusted or repaired and which may be assembled and adjusted to variable jaw ridge sizes, and formed with self-curing hardened resins. The foundation supports prosthetic teeth and is permanently but removably secured to the jaw by implants embedded in hard dental tissue, such as tooth stubs or bones. The dentures can be readily repaired or adjusted for changes in the jaw of the patient, by chairside techniques available to dentists. The foundation can also be adjusted to changes in size and shape of ridges in the jawbones for more comfortable use of the dentures secured on such prostheses.

摘要： The invention concerns bone-adaptive surface structures for lateral jaw implants. Micromechanical and/or macromechanical surface structures having various body forms are incorporated into selected segments of the surface of the base and of the bar that connects the threaded piece 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.

摘要： An immediate provisional implant is provided, and method of use therefor, that serves to protect permanent dental implant anchors and overlying tissue during the healing and osseointegration process. Potentially damaging forces resulting from patient use of a temporary prosthesis during the osseointegration period are carried by the immediate provisional implant, rather than impinging upon non-osseointegrated permanent implant anchors or overlying tissue. The immediate provisional implants are self-threading and are inserted in osteotomies located near permanent dental implant anchors. The temporary prosthesis is removed after a period allowed for osseointegration of the permanent implant anchors, and the provisional implants can also be removed at the same time. The immediate provisional implants are non-linearly tapered from a maximum thread diameter near the bone surface to a more narrow distal end, providing immediate stability without the benefit of osseointegration.

摘要： The position of intra-osseous implants and abutments to analogs is enabled and enhanced by using the longitudinal axial locked position of a post (12a) of an implant (12) having a locking taper in a bore (10a) of an implant (10) having a generally matching locking taper as a reference to determine the position of a stop surface (14c) on impression posts, abutment analog posts and the like received in the bore of an implant and implant analog. In another embodiment the bore (16) of an implant analog (16) is provided with a shelf (16c) located at a position determined by the axial distance of the locked position of the abutment post to prevent over-seating. Controlled retentive resistance and stability of a post is provided by using flats formed in the bore of an implant analog and by forming rings on a post receivable in the bore of an implant or implant analog. One such ring (18c) is formed with an outer periphery sized and configured to allow bending of the outer peripheral portion in a direction opposite to the direction of insertion in a bore to provide greater retentive resistance than insertion resistance.
