Osteosynthesis Plate Comprising Through-Openings Which are Inclined in Relation to the Plane of the Plate
An osteosynthesis plate is described, which is suitable for treating jaw fractures. The osteosynthesis plate has a plane of the plate as well as two plate sections 12, 14 with associated longitudinal axes 16, 18 extending substantially within the plane of the plate and inclined or staggered with respect to one another. Through openings 20, 22 inclined to the plane of the plate are formed in each of the two plate sections 12, 14. The angular alignments of the through openings 20, 22 within the plane of the plate differ with respect to a longitudinal axis 16 serving as reference line from one another by less than approximately 60°. In applications in the jaw region this slight deviation of the angular alignments permits an intraoral securement of the osteosynthesis plate. A transbuccal access through the cheek can thus be dispensed with.

Dental implant system
A dental implant assembly is provided, as well as a system and method for exposing an embedded implant after osseointegration has taken place. The implant assembly comprises an implant member for embedding in the jaw and a rest factor member for securing to the implant member, the rest factor member having an upper rest surface just above the tissue level for opposing an overlying portion of a prosthesis anchored elsewhere in the jaw to form a non-retentive rest or support for accepting down pressure from the prosthesis. The implant member is relatively short and can be installed in distal jaw regions without interference with the mandibular nerve. A bore is cut out in the jaw for receiving the implant, inserting the implant and an attached healing screw in the implant. The implant site is closed and osseointegration takes place over an extended period. Subsequently, the implant site is uncovered, the healing screw is removed, and the rest factor member is secured in the implant.

Screw-in Enossal Dental Implant
InactiveUS20080145819A1Prevent penetrationEffect healing processDental implantsJaw boneMaximum depth
A screw-in enossal dental implant comprising a base body with a thread arrangement which can be multiple-threaded, and notches, in addition to an upper part and a bulged enossal part. The thread arrangement on the base body is defined by parabolic curves forming intersection points outside the area of the dental implant. The thread arrangement extends as far as the upper part. The flank angle of the thread flanks is 20 DEG. The transition between the base body and the bulged enossal part is rounded. The maximum depth of the notches is ⅓ of the diameter of the base body and the width thereof is at least as large as the width of the respectively remaining thread arrangement between the notches. The dental implant causes the compression forces acting upon the jaw bone to tend unevenly towards zero as the screw-in depth increases, enabling reliable fastening in the enossal area.

Rigid Mask for Skiing and Snowboarding
A facemask for skiing, snowboarding, and other winter sports integrates with traditional goggles by use of a temple-trough system that secures the goggle headband and places the goggle headband on top the facemask headband. Diffusing foam circumscribing voids at the cheek areas provides even ventilation and prevents over chilling of the cheeks. Foam at the perimeter of the mask and at the nose bridge area keep the mask off the user's mouth and nose tip. The design at the jaw region allows movement of the head and the use of a jacket collar or scarf. In an alternative embodiment, a bridge-flare system at the nose area allows the mask to conform to a wide variety of nose sizes and shapes.

Technique for installing dental implant assembly
A technique for installing in the maxilla of a patient a dental implant assembly having a root section, a post section and a nut or locking element section. The root section is treaded to define a self-tapping screw which at its rear end is attachable to the post section and at its front end to the locking element section. To carry out this technique, the root section is screwed into a hole bored in the maxilla, the nose at the front end of this section then projecting into tie adjacent sinus cavity. The membrane lining the sinus cavity is lifted to admit the locking element section which is then attached to the nose to lock the root section to the maxilla. Then a charge of bone particles is deposited in the cavity to cover the nut section and the surrounding maxilla region. In a time period lasting several months, the bone particles gradually fuse with and graft onto the maxilla to augment its structure and embed the locking element section therein. Concurrently in the same period, the root section proceeds to fuse with the maxilla. This period of concurrent activity represents the total time it takes to complete the dental implant installation, after which it is feasible to mount a dental bridge on the post section.

The invention relates to a method and system for determining a sharp panoramic image constructed from a group of projection images, especially the invention relates to defining a structure of the panoramic X-ray image of an area of a dentition and of jaws. The structure of a panoramic image to be generated from a group of projection images is determined by at least two crucial parameters, namely parameters of the central surface S of the sharp layer and thickness t(s) of the sharp layer, using penalty function F(S,t), which is at least a penalty function F3(S,t) of low-frequency changes in the computed panoramic image corresponding to the choices S and t(S). After computing F3(S,t) the best center surface and thickness function (in other words the sharpest layer of the panoramic image) is obtained by minimizing said penalty function F(S,t) over parameter space.
