Abstract: In an arrangement for obtaining reliable anchoring of a threaded implant (3) in dentine, a hole (2) is made in the bone substance. In the side wall (2b) of the hole it is possible to establish an internal threading which can cooperate with an external threading (3d) on the implant. The implant threading is arranged to force the bone substance out in essentially radial directions as a function of the extent to which the implant is screwed into the hole. The threading is arranged to effect greater forcing out of the bone substance at the outer parts of the hole than at the inner parts of the hole. The degree of forcing out is adapted in relation to the softness of the bone in order to achieve the reliable anchoring. Along at least part of the longitudinal direction of the implant, the implant threading can be given a non-circular configuration for the purpose of obtaining improved rotational stability in soft/weak bone.

Abstract: A surface structure is produced on an outer surface of an implant or a fixture and forms a base structure in a range of implants related to different types and qualities of jaw bone. During production of the surface, parts of a turning tool are placed against the implant or against a blank which is intended to form the implant. The parts and/or the implant are assigned controls which give rise to mutual displacements between the parts and the implant so that the parts follow a substantially spiral trajectory along the outer surface. By means of said controls, a long wave pattern is formed with successive peaks and with through lying between these. In this connection, a through can be arranged adjacent to the outer parts of an existing thread. The controls are chosen so as to produce through depths in the range of 25 to 250 ?m, preferably 50 to 200 ?m. The invention also relates to an implant which bas the same character as the implant produced by the method.

Abstract: The current disclosure is directed to a dental implant system and method that modifies the screw access channel of an implant-supported abutment in order to improve cement retention within the abutment chamber and to improve retention strength of prosthesis. The cement-retaining system comprises an abutment screw and a longitudinal extension of the abutment screw that channels excess cement into the chamber.

In one implementation, the extension is affixed at the head of an abutment screw. In other implementations, the extension and the abutment screw are a continuous unit. Experiments demonstrate that the extension increases the volume of cement within the abutment chamber and improves the retention ability of the abutment-restoration complex.

Abstract: An endosseous dental implant for guided regeneration of gingival tissue onto the implant and method of producing the same is prepared by coating a region of the implant with biocompatible, random or aligned microfibers or nanofibers to which gingival epithelial and connective tissue cells may become attached. The fibers may be degradable or nondegradable. The extracellular matrix of new connective tissue forms and connects to the implant surface, guided by the nanofibers or microfibers. The coated implant prevents bacterial biofilm formation, which can cause detrimental resorption of crestal bone and lead to implant failure. The implant surface supports improved tissue bonding and provides a cost-effective approach to coating the dental implant surface with biomimetic fibers to enhance gingival or other tissue regeneration directly onto the implant surface.

In one exemplary embodiment, the drive tool includes an elongate body having an opening at its proximal end which is sized to receive the head portions of at least two different dental implants, the head portions of the dental implants being oriented at different angles with respect to the implant body portions. When the head portion of an implant is received within the opening, the drive tool is rotationally locked with respect to the implant. In this position, the body of the drive tool remains oriented so that same is substantially colinear with the body portion of the implant. Although the invention is described in the context of a drive tool used with a dental implant having a body portion and a head portion or abutment portion, the invention is more broadly applicable to drive tools which may be used with other types of orthopedic screws.

Abstract: The invention provides a dental implant including a neck portion, a bottom portion and a body portion. The body portion connects the neck portion and the bottom portion.

Along a long axial direction and a direction from the first end to the second end, the cusp widths of the threads gradually increase, or heights from the cusp to the root of the threads gradually decrease. Therefore, the dental implant can be used to gradually squeeze and expand the alveolar bone and meanwhile improve the density of the alveolar bone, so that the dental implant has desirable initial-stage stability after the dental implant surgery, thereby solving the micromotion phenomenon after the instant dental implant surgery, and facilitating subsequent osseointegration.
