    Abstract: An orthodontic bracket comprises a bracket body with a mesial distal extending arch wire slot and a ligating latch spring member having the form of a thin flat metal strip. The spring member comprises along its length, in the order stated, an anchor portion anchored in the bracket body, a flexing portion in which the majority of the flexing takes place, a ligating portion that closes the slot mouth and engages any arch wire therein, and a latching portion by which the spring member is latched to the bracket body. The spring member may comprise a biasing portion between the flexing and ligating portions at the slot occlusal surface, or between the ligating and latching portions at the slot gingival surface, this biasing portion being convex toward the slot lingual wall and protruding into the slot to press the arch wire into the respective slot wall junction for more precise control. The bracket body may be made as two mirror image parts which are laser welded together and between which the spring member is mounted. The latches between the spring member and the bracket body may comprise notches in the spring edges that are engaged by latch sears on the body, and two labially lingually spaced sears may be provided. Preferably the spring member is made of a nickel titanium shape memory alloy. The bracket body may have two pairs of tie wings for reception of an external ligature between which the spring member is disposed.

    Abstract: A device for obtaining the fitting of a matrix to a tooth to be filled comprises matrix (5) and wedge (4) or its attachment part (7) made of resin "with memory that is deformable by illumination". The device is made such that when it is illuminated it deforms and pushes matrix (5) to precisely occupy the radicular recess of the tooth to be filled, while when it is not illuminated it again assumes its normal shape. Thus, one obtains a perfect filling that perfectly fits the shape of the tooth.

    Abstract: An artificial dental root having the function of a natural dental root is characterized in that the artificial dental root is made a shape-memorizing alloy capable of changing the apex morphology of the artificial dental root after implantation so as to stay in the jawbone. The artificial dental root is implanted in an alveolus and the apexes thereof then closely contact the inner surface of the alveolus owing to the shape-memorizing effect thereof to fix the dental root firmly in the alveolus.

    Abstract: A process for straightening teeth using super-elastic NiTi arch wires of the same diameter but having different recovery forces is carried out by using NiTi wires that have a transition temperature below body temperature with brackets on the teeth. The different recovery force is set for each wire by heat treating the wires at different temperatures and/or for different periods of time. In this manner the forces applied to the teeth can be changed while still using arch wires of the same diameter.

    Abstract translation: 使用具有相同直径但具有不同恢复力的超弹性NiTi拱形线矫直牙齿的方法是通过使用具有低于体温的转变温度的尼钛线，并且在牙齿上具有托架来进行。 通过在不同温度和/或不同的时间段内热处理电线，为每根导线设定不同的恢复力。 以这种方式，可以改变施加到牙齿上的力，同时仍然使用相同直径的弓丝。
