| 101 | Manipulable dental model system for fabrication of a dental appliance | US09454786 | 1999-12-03 | US06227851B1 | 2001-05-08 | Muhammad Chishti; Loc X. Phan |
| The present invention provides a manipulable or reconfigurable dental model system and methods for its use to model a series of tooth configurations corresponding to sequential tooth movements during an orthodontic treatment. When a patient undergoes orthodontic treatment, teeth and bite configurations are realigned in a series of stages. Each stage represents a new pattern or dental configuration that will eventually lead to a proper final positioning of the entire dentition. Progress from the initial configuration, through the intermediate stages and finally to the final configuration may be accomplished using any one or a combination of different dental appliances. Of particular interest to the present invention, many of these appliances may be made using a dental mold representing the patient's dental configuration. In particular, thermoformable plastic positioning appliances which fit over the patient's teeth may be formed over a three-dimensional mold of the patient's dentition. When successive appliances are used throughout treatment to reposition the teeth from initial to final configuration, a new mold has typically been produced to fabricate the appliance for each stage. The present invention provides an apparatus and methods which employ a manipulable or reconfigurable mold to model patient dentition and gingiva at each stage of treatment. | ||||||

| 106 | Dental articulator and method | US582387 | 1996-01-03 | US5672055A | 1997-09-30 | Ioannis Koutavas |
| A method of determining the position of an upper jaw cast and a lower jaw cast using a dental articulator provides a disposable plastic holder in the lower jaw cast and mounts it in a metal bracket bar fitted to the base of the articulator whose telescoping post allows adjustment of the height of the head above the base. A bracket bar mounted on the head and spring biased so that this bracket bar can move in a plane and can pivot about a horizontal axis receives another plastic disposable holder which can fit into a cavity in the upper casting. Once the castings are properly positioned, a hardenable composition can be cast into the recess to embed the holder in the upper casting. | ||||||
| 107 | Pin stabilizer for dental model | US406164 | 1995-03-17 | US5611686A | 1997-03-18 | Tyrone A. Silva |
| A pin stabilizer fir dental models (14) has a plurality of positioning pins (1) extended from an articulator base plate (2) for insertion into positioning sleeves (3) that are cast in a dental model while the positioning pins are in the positioning sleeves. Quickly and easily then, the dental model can be attached repeatedly to and detached repeatedly from a dental articulator (15) to which the articulator base plate is affixed for work on a dental model. The positioning pins and the positioning sleeves can be made of materials which do not deform from repeated use.

| 108 | Method for creating a dental model | US144558 | 1993-11-02 | US5466152A | 1995-11-14 | Jose Walter |
| A dental articulation apparatus for creating a pinned model of a patient's mandibular and maxillary dental arches. The apparatus permits the simultaneous relation and construction of pinned, segmental models of the maxillary and mandibular dental arches and allows the model, die, and articulation to be accomplished in a single pouring. The articulator includes recessed maxillary and mandibular tray support members each containing a plurality of indexing holes into which indexing pins can be inserted. A negative dental impression is then filled with a casting material, or alternatively, the support members are filled with a casting material, and the support members and negative impression material are then joined together such that the indexing pins protrude through and into the casting material. Once hardened, the casting material can be removed from the articulating device; the positioning pins allow then sectioned portions of the model to be replaced in the exact position that they were before the model was sectioned. Antirotation devices found on each tray support member prevent the model from turning on its pin axis thereby increasing stability and holding the model accurately in place. | ||||||

Each slide member has retaining flanges and positioning means engageable with an articulation tongue member for insuring that the slide member is always accurately positioned in a single unchanging position on the tongue member; each slide also has anchor means engageable with a connecting mass of self-setting hardenable material in which the gum portion of a dental model is embedded so that upon hardening of the connecting mass the model supporting slide, the connecting mass and the model constitute a unitary structure which can be removed from the articulation tongue but can be returned to its original position on the articulation tongue. | ||||||
| 115 | Dental model articulator | US953442 | 1978-10-23 | US4207677A | 1980-06-17 | Barry Lampert |
| The upper and lower jaw members and intermediate connecting member of a dental model articulator are molded from suitable plastic as an integral unitary whole; with the jaw members spaced from each other, by the intermediate connecting member, a distance comensurate with the dental models to be mounted on the articulator, and so that the upper jaw member articulates with respect to the intermediate member and lower jaw member to facilitate relative positioning of, and the performing of work on, the dental models. An over-center toggle-type-hinge is integrally molded between the upper jaw member and the intermediate connecting member to provide for articulation of the upper jaw member. Each jaw member has formed therein a centrally disposed slot with shoulders extending from each wall thereof so as to leave a narrow passage or slit formed to receive a rib of a dental model mounting plate and thus to facilitate positioning of the plate, and a dental model when carried thereby on its respective jaw member of the articulator. The rib of the dental model mounting plate is formed in a modified "T" shaped configuration to enter into the slit between the shoulders while at the same time snugly positioning such shoulders between the arm of the "T" and the corresponding surface of the mounting plate. Suitable apertures and ribs are formed in the jaw and connecting members to facilitate its production while at the same time providing a required degree of flexible rigidity. | ||||||

A lower jaw member is also mounted on the support frame and is adapted to receive a lower dental arch cast. Movement of the lower jaw member in protrusive and retrusive directions and in a lateral direction is controlled by a ball and slot hinge arrangement in combination with a movable anterior platform mounted on the support frame and a forward pin connected to the lower jaw member and which engages and is movable relative to the anterior platform. The anterior platform is provided with sloping planes on which the forward pin moves to guide the lower jaw member in order to duplicate the dropping of the lower human jaw during lateral movement. | ||||||

| A novel articulating apparatus, a novel bite registration guide, and a new procedure for diagnosis and study are used for the mounting preparation and arrangement of my stereodont Orthodontic Study Model of U.S. Pat. No. 3,787,979, granted on Jan. 29, 1973. In the form of my guide and my new articulator and my Orthodontic Study Model, there is reproduced very accurately the orthodontic parameters of the patient's dentition. The Orthodontist with this new articulator, bite registration guide, and my study model has a new and powerful tool which he can utilize in diagnosis and in treatment planning to shorten the treatment time and have better control of the desired tooth measurements.The novel procedure comprises sequential stages as follows:Stage A: The coronal assemblies of the Orthodontic Study Model are provided with the stone models of the crowns of the upper and lower teeth of the patient;Stage B: The completed coronal assemblies of Stage A are coupled to my new bite registration guide in the Orthodontic Study Model to form a triad of upper and lower models with the bite registration guide; and,Stage C: The triad obtained in Stage B, consisting of coronal assemblies coupled to a bite registration and mounted on the Orthodontic Study Model, is now mounted in my new geared articulator. In the mounted position the triad assembly is an accurate reproduction of the orthodontic parameters of the patient's dentition and serves as a basis for charting future movements of each of the teeth in x, y and z directions to provide reproduceable and highly accurate monitoring of orthodontic treatment. | ||||||
