Abstract: An orthodontic separator, dimensioned such that it can be inserted between adjacent teeth. The separator is characterized in that it exhibits an increase in compressive force after insertion between adjacent teeth in the oral environment. The separator, after insertion, exerts sufficient force on the adjacent teeth to push the teeth apart.

Abstract: An orthodontic appliance such as a bracket or buccal tube has a latch for retaining an archwire in an archwire slot. The latch releases the archwire from the archwire slot whenever the archwire exerts a force in a generally buccolabial direction on the appliance that exceeds a certain minimum value. The minimum value is less than about one-half of the force required in the same direction to debond the appliance from the tooth, and thus reduces the likelihood that the appliance will unintentionally debond from the tooth during the course of orthodontic treatment.

Abstract translation: 诸如支架或口腔管的矫正器具具有用于将弓丝保持在弓丝槽中的闩锁。 每当弓丝在器具上大体上积分方向施加超过一定最小值的力时，闩锁将从弓丝插槽释放弓丝。 最小值小于同一方向从牙齿脱离器具所需的力的大约一半，从而降低了矫正治疗过程中器具将无意中脱离牙齿的可能性。

Abstract: The present invention provides a Ni--Ti--Pd superelastic alloy material of a composition consisting of, by atomic percent, 34 to 49% nickel, 48 to 52% titanium and 3 to 14% palladium. Optionally, in a part of nickel and/or titanium of this alloy is replaced with one or more elements selected from a group of Cr, Fe, Co, V, Mn, B, Cu, Al, Nb, W and Zr such that these elements to be replaced amount to 2% or less in total (by atomic percent), wherein a stress hysteresis between the loading and unloading stresses in the stress-strain curve at temperatures between Af and Af+5.degree. is as small as 50 to 150 MPa. Since the Ni--Ti--Pd superelastic alloy material having the above composition is excellent in hot workability, it can be hot-worked into a wire having a diameter up to the range from 1 to 5 mm and manufactured at a low cost. Then, a final heat-treatment is given to the hot-worked material at a temperature in the range from 300 to 700.degree. C. through a step of final cold-drawing at a reduction ratio in a cross section area of not less than 20%, whereby an excellent superelastic material is obtained, with a stress hysteresis in the range from 50 to 150 MPa, and a residual strain of 0% or close to 0% after unloading, and which can be suitably used for an orthodontic archwire.

Abstract: A torqued archwire for use in an edgewise orthodontic bracket system. The archwire is substantially rectangular in cross-section, is made of titanium-based alloy and has a plurality of segments, including an anterior segment which is sized to cooperate with brackets attached to a person's central and lateral teeth. Torque is built into this anterior segment, being maximized at the centerpoint and adjacent the central teeth brackets and then decreasing continuously along the remaining length of the segment. Extending from the respective ends of the anterior segment are a pair of transition segments, in which the torque built into the archwire diminishes to zero. The lengths of the transition segments are such that these "zero" points occur, in use, between the corresponding adjacent lateral and cuspid brackets. Posterior segments of the archwire, which extend distally from the transition segments, generally include no built-in torque. For ease of reference by an orthodontist, the "active" anterior and transition segments of the archwire are colored with non-toxic ink.

Abstract translation: 用于沿边正畸托架系统的扭曲弓丝。 弓丝的横截面基本上是矩形的，由钛基合金制成并且具有多个段，包括前段，其大小适合与附接到人的中央和外侧齿的托架配合。 这个前段内置有扭矩，在中心点处最大化，并与中心齿支架相邻，然后沿着该段的剩余长度连续减小。 从前段的相应端部延伸的是一对过渡段，其中内置于弓丝中的扭矩减小到零。 过渡段的长度使得这些“零”点在使用中在相应的相邻的侧向和尖括号之间出现。 从过渡段向远端延伸的弓丝的后段通常不包括内置扭矩。 为了方便由正牙医生参考，弓丝的“活动”前部和过渡段用无毒墨水着色。

Abstract: An orthodontic bracket comprises a bracket body with a mesial distal extending arch wire slot and a two-armed ligating latch spring member mounted thereon. The two arms comprise a ligating inner portion and a latching outer portion joined by a connecting portion and the spring member is movable between an unlatched slot open position and a latched slot closed position in which the slot is closed by the ligating portion and the spring member is latched to the bracket body by the latching portion. The bracket body may be made as two mirror image parts between which the spring member is mounted, the two body parts thereafter being fastened together. Each body part may carry a cylindrical mesial distal extending pivot post, the spring member being mounted on the posts for pivoting movement relative to the bracket body, the posts and spring member being frictionally engaged as it moves between slot open and closed positions for frictional damping of the pivoting movement. 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 preferably the latch sears have cam acting labial faces producing gingival movement until the latches are engaged. Preferably the spring member is made of a nickel titanium shape memory alloy. The bracket body may have one or two hook members for attachment of a traction spring member. It may instead have two pairs of tie wings for reception of an external ligature between which the spring member is disposed.

Abstract: Orthodontic archwires and methods of making such archwires. The archwire includes a shape memory alloy having a preset shape for exerting forces on teeth during orthodontic treatment. The alloy, which preferably is comprised of at least three elements (e.g., Ni, Ti and Cu), has a transformation temperature (A.sub.f) greater than about 25.degree. C., whereby the orthodontic archwire produces forces at normal mouth temperature which are greater than the forces produced at normal room temperature. The orthodontic archwire also preferably has a variable modulus of elasticity.
