    摘要: A low profile orthodontic appliance and method of designing custom and standard low profile orthodontic appliances are provided. The archwire of the appliance is not parallel to the dental archform but converges toward the archform preferably in the vicinity of the incisors. Slotted brackets on either the laterals, the cuspids or the first bicuspids have mesially rotated slots to support the archwire in sloped relation to the teeth. For standardized appliances, the slot rotation may be provided only in brackets for the upper laterals and the lower cuspids. For Caucasians, the preferred rotation angles are 4.5 and 6 degrees respectively. For Asians, the rotation angles are preferably distributed over brackets for the laterals, cuspids and first bicuspids. Tooth to archwire spacing is not more than 0.05 inches for all teeth but the upper laterals. The archwire shape is designed in custom appliances by digitizing tooth shape of a patient, calculating ideal finish tooth positions and ideal bracket positioning, designing an optimally smooth archwire spaced optimally close to the teeth and manufacturing brackets with calculated slot rotations in most of the brackets. For standardized appliances, statistically average anatomy or appliance designs follow the custom appliance design method, except that only the most significant slot rotation angles are fabricated.

    摘要: Custom orthodontic brackets are provided for supporting an orthodontic archwire at custom positions and inclinations on the teeth of a patient. The preferred brackets each include a bracket base mountable on a tooth and a support extending therefrom for supporting an archwire, preferably in a slot of the custom inclination, depth and preferably curvature with respect to the mounting surface of the bracket base to the tooth. In the preferred embodiment, the brackets are formed by mounting blanks on an inclinable holder, positioning a cutter blade and inclining the holder to cut a custom slot in an archwire plane through the support on the bracket. The cutting tool and bracket holder are computer controlled and driven by signals produced from digitized data relating to the individual patient's anatomy, and preferably to tooth finish positions and bracket and archwire geometry calculated from digitized data taken from the patient's mouth or model thereof.

    摘要: A model of the teeth in a patient's mouth and a prescription of desired positionings of such teeth are provided by the patient's orthodontist. The contour of the teeth in the patient's mouth is determined, preferably digitally, from the model. Calculations, preferably digital, on the contour and the desired positionings of the patient's teeth are then made to determine the geometry (e.g. grooves) to be provided in brackets for receiving an arch wire to form an orthodontic brace. Such geometry is intended to provide for the disposition of the arched wire on the brackets in a progressive curvature in a horizontal plane and a substantially linear configuration in a vertical plane. The geometry of the brackets is altered (e.g. by cutting grooves in the brackets at individual positions and angles and with particular depths) in accordance with such calculations of the bracket geometry. The brackets may be disposed on the model of the patient's teeth at positions dependent upon such calculations. A mold may be formed of the model of the patient's teeth and the brackets on such teeth. The model and the mold may be shipped to the orthodontist with written instructions for the disposition of the brace on the patient's teeth. Alternatively, an information sheet may be prepared, after the calculation of the bracket geometry, to specify the placement of the brackets on the patient's teeth and the disposition of the arch wire on such brackets. The brackets and the information sheet are sent to the orthodontist.

    摘要: An artificial posterior denture tooth comprising a body shaped to conform generally to the shape of a natural posterior tooth and formed of a plurality of resin materials varying in hardness, wear resistance and strength. The various resins are selectively distributed throughout the body of the tooth to produce an uneven wear pattern consistent with expected changes in the patient's stomatognathic system.

    摘要: Zero-degree posterior teeth for a lower and an upper denture, wherein opposite posterior teeth interact at least substantially in line contact. The contour at the level of the active surface of the posterior teeth closely resembles the contour of natural posterior teeth. In each pair of opposite posterior teeth the lingual or palatal contour section of one posterior tooth is provided with a line shaped masticatory rim and the buccal contour section of this posterior tooth is provided with a masticatory plane, while the palatal or lingual contour section of the opposite posterior tooth is provided with a masticatory plane and the buccal contour section of this opposite posterior tooth is provided with a line shaped masticatory rim. The posterior teeth are provided with evacuation channels in their active surface, which channels originate near the line contact between opposite posterior teeth, their depth gradually increasing towards their end at the contour.

    摘要: A set of artificial molar teeth composed of two respective upper and two respective lower premolars and two respective upper and two respective lower molars, wherein at each pair of superimposed teeth the one tooth has a mastication furrow or groove and the other tooth at the side of the gum possesses a protuberance coacting with the mastication groove of the one tooth. In order to realize successive contact of the teeth of the first premolars to the second molars there is provided a stepped reduction of the tooth angle and/or a stepped reduction in the size of the friction path.
