摘要： Plastic orthodontic appliances having improved bonding characteristics are described. The appliances have a polymeric base with projecting structure extending outwardly therefrom and an applied coating of a chemically activatable material. The projecting structure includes a broadened outer extremity and undercuts proximate the outer extremity which form mechanical bonds with a bonding adhesive. The chemically activatable material applied to the projecting structure increases the chemical bond between the structure and the bonding adhesive and thereby enhances the overall bonding characteristics of the appliance. Another aspect of the invention concerns a method of enhancing the bond strength of plastic orthodontic appliances. The method includes applying a chemically activatable material layer by sputtering, plasma deposition, or other deposition process, to a plastic orthodontic appliance having projecting structure. In a preferred embodiment, the projecting structure is a plurality of posts, and the chemically activatable coating is SiO.sub.2. It is further contemplated that the chemically activatable coating may be activated by treatment with silane.

摘要： Corrosion resistant instruments such as those used in medicine and dentistry are efficiently made from raw materials that are difficult to machine. Round bar stock is rolled or otherwise deformed to have flat sides and rounded edges. The parts of the instrument are cut from the flattened bar, by combinations of transverse and longitudinal cuts, so that the rounded edges of the bar define the shape of convexly curved finish surfaces of the instrument. Expensive machining steps are eliminated. An orthodontic pliers is particularly disclosed, made according to the method, by making one or more Z-shaped cuts that preserve the rounded sides to define the outer surfaces of a handle and opposing jaw on each of two plier parts, pivotally joined together.

摘要： Plier-type cutters for cutting metal objects having a pair of plier halves which are each of one piece construction and made of a hardenable stainless steel. Each plier half has a cutting edge hardened to a cutting hardness suitable for cutting the metal object, such as an orthodontic metal appliance, without fracturing during normal use. Each plier half has at least one fracture sensitive portion, excluding its cutting edge, which would be susceptible to fracturing during normal use if hardened to the cutting hardness. Each fracture sensitive portion has a working hardness which is sufficiently lower than the cutting hardness to substantially limit, if not eliminate, the likelihood of fracture during normal use. The present plier-type cutters with differently hardened regions may be obtained by fully hardening each plier half to the desired cutting hardness and then selectively tempering at least the fracture sensitive portions of each while keeping at least the cutting edges relatively cool to prevent significant softening thereof.

摘要： A crystalline orthodontic bracket which has been subjected to a machining operation having improved fracture toughness and a heat treatment method for obtaining such improved fracture toughness. The method includes the steps of placing the machined orthodontic bracket in an oven and heating the bracket at an elevated temperature above normal annealing temperatures and slightly below the melting point of the brackets which is capable of healing surface microcracks. The bracket is maintained at this temperature for a predetermined period of time so as to heal microcracks on the surface. The bracket is then removed and allowed to cool to room temperature.
