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 μm, preferably 50 to 200 μm. The invention also relates to an implant which bas the same character as the implant produced by the method.



SCANBODY

Embodiments include a scanbody that includes a base that fits in an anti-rotation geometry of a dental implant, and a body that is set to be scanner. The body includes a lateral surface with geometrical elements that allow the identification of information regarding a position, direction and rotation of the scanbody. The body lateral surface does not include any flat portion and includes a first opposing trunconical element, base-to-base, a secondary trunconic element and concave surfaces disposed at the side, including a hole (5) that receives a fixing screw.



ORTHODONTIC BRACKET AND METHOD OF CORRECTING MALPOSITIONED TEETH

An orthodontic bracket includes a bracket body and a ligating member. The ligating member retains an archwire in an archwire slot and includes archwire control structure including projecting portions spaced apart in a mesial-distal direction with a recessed area therebetween. The recessed area and the projecting portions overlie the archwire slot. The recessed area may include a flat or a curved surface in a mesial-distal direction. The recessed area and projecting portions may define a radius of curvature that is less than the radius of curvature of the archwire seated in the slot. The archwire contacts one or both the projecting portions resulting in a larger moment arm and better rotational control of the bracket with the force applied by the archwire.



ORTHODONTIC APPLIANCE AND ORTHODONTIC TREATMENT USING THE SAME

An orthodontic appliance, includes a crimpable tubular shaped portion having at least three walls selected from the group consisting of a lingual wall, a buccal or labial wall, an occlusal wall and a gingival wall, the at least three walls defining and opening configured to receive an archwire therethrough in a mesial-distal direction. The appliance includes at least one wing joined to the tubular shaped portion, the at least one wing extending longitudinally in the mesial-distal direction. A slot is provided in the at least one wing open to an end of the wing in the mesial or distal direction and having a depth in the mesial distal direction and a height in a gingival-occlusal direction configured to receive a ligature wire or elastic.
