DENTAL FACE BOW.
Application filed December Heretofore' face bows have been provided which permit of a certain adjustment ofthe matrix-holding plate relatively to the pivot blocks locating such plate in the articulating machine and adjusting such blocks to correspond with the temple mandibular joint. Such bows, however, have not been so provided as to permit of adjustmentv to all variations of the relation between the plane of the maxillary fridge and consequent ly have notaflorded in the articulator a possibility of the same relation oil condyle movement as occurs in the mandible of the patient. The present invention permits of a complete adjustment of thepivotal blocks of the bow so as to make it possible to control the relation between the matrix holding plate and the matrix thereon sothat the condylc action of thepatients mandible may be with approximate accuracy duplicated in the articulator. Features and details of the inventionwill appear from the specification and claims.
The invention is illustrated in the accompanying drawings as follows Fig. 1 shows a side elevation of the bow in position for measurement and a skull indicating its general location relatively to the mandible.
Fig. 2 a plan view of the bow.
Fig. 3 a side elevation of an articulator with the bow in place therein, the bow being broken away to better show construction.
Fig. 1 a plan view of a portion of the articulator with a part of the bow in place.

1 and 2 mark the matrix-holding plates. These are adjustably mounted on the U-har of the how 3. Each plate is provided with a block 4 having an opening therethrough through which the bar extends to permit the sliding movement of the plate on the bar, each block having a slot 41- and a clamping screw 5 so that the block may be clamped to the U-bar and thus the plates adjusted relatively thereto. A scale 6 is arranged on the U-bar so that a reading may be taken as to the position of the plates both for centering and for repeating adjustments. The rearward branches 7 of the U-bar extend through openings 9 in the block 8 and set screws 10 are provided in the blocks 8 by means of which they may be locked in any adjustment along the bar. Upright pins 11 are arranged in vertical openings, 12

in the blocks 8. These are slidingly mounted in the openings and are clamped by clamping pins 13 arranged in openings 1 1 so that as the set screws 10- are set to clamp the blocks on the branches the same clamping action,
operating through the bar 7 against the pins 13, clamps theverticalpins 11 in their de sired adjustment in the block so that there is a single locking. of both adjustments. Heads 15 are arranged on the tops of the pins 11 and the pivotal rods 16extend through cross openings 17 in the heads 15. The rods 16. are provided with pivotal blocks 18 at their ends, these being each provided with a trunnion-receiving socket l8. Scales 19 are provided onthe U-bars indicating a reading as to the position of the blocks 8 longitudinally of the plates 1 and 2. Scales 20 are provided on the vertical rods by means of which the vertical ad justments of the pivots relatively to the plane of the plates 1 and 2 maybe indicated and scales 21 are provided on the rods 16 by means of which the axial positionof these rods may be indicated. After the matrix is formed and the plates 1 and 2 adjusted to the plane of the maxillary ridge the pivotal blocks 18 are each independently adjusted to the focal point of the mandibular joint and this adjustment read and recorded. In Fig. 1 the skull A with an occlusal plane B along the maxillary ridge is clearly indicated and a matrix is indicated in place therein. After the removal ofthe how it is placed, as usual, in the art-iculator but in at;
complishing this a post or stop is adjusted relatively to the vertical adjustment of the vertical rods 11. This is accomplished in the present structure as follows: The plate 1 has a slot 22 and a mounting 28 has a screw threaded extension extending through this slot. A nut 24 is arranged on the upper end of the extension by means of which the mounting may be clamped on the plate 1 as adjusted along the slot 22. A stop rod 25 is slidingly mounted in an opening 23 in the mounting 28 and is locked in ad ustment relatively to the plate 1 by a set screw 26. A scale 25 is provided and this scale corresponds with the scale on the vertlcal rod 11 so that the plate when placed in the articulator will have the same angular relation llU later, the articulator being one of common from and has a base 27 with two upright posts 28 at its rear end. Thee carry the ring bearings 29 at their upper ends in which rotative blocks 30 having the condyle slots 31 are arrangeth the blocks being locked in adjustment to vary the inclination of the slot 31 by screws 32 extending through slots 29. The articulator is provided with trunnion extensions Sat which correspond to the axes ot the mandibular joint and the sockets 18 in the pivot blocks 18 are adjusted on these extensions 34;, the scales on the rods 16 being utilized to center the plates 1 in the articulator. The stop rod 525 is adjusted with its scale corresponding to the adjustment of the vertical rod; 11 so that the plate assumes a parallel position relatively to the base and consequently is in the same relation tothe pivotal point of the articulator as in the patientumler all condi tions, it being lmderstood that the posts 28 are rotatable so that-the blocks 30 not. only are swung to vary the inclination of the slot 31 but a re also swung-to incline thesevblocks to a central vertical plane.
\Vith this adjustmentof the pivotal-point of the bow vertically and longitmlinally, each adjustment being possible indepeiulently of the other itis;possible to get anepcact relation inthe articulator between the plate mounted therein and the pivoted mountings for the plate as is the mandible inthe patient from which the matrix istakenand consequently a movement approximating exactly the condyle path-x ot the mandible is made possible and an adjustment of the dental structures corresponding thereto is also made possible.
that I claim as new is: I
1. In a dental t'ace how. the combination of a matrix-carrying plate; a U'har on which the plate is mounted: pivotal blocks on each branch of the U-bar adjustable vertically and longitudinally relatively to the plate: and a vertically adjustable stop connected with theplate.
2. In a dental 'tace how. the conibiiuit-ion of a matrix-carrying plate; a U-bar on which the plate is mounted; vertical rods mounted on each branch oF the .U-bar and adjustable vertically relatively to the U-bar; pivot blocks carried by the vertical rods; and a vertically adjustable stop connected with the plate.
3. In a dental taco how, the combination ot a matrixaiarrying plate; a *U-bar on which the plate is mounted; vertical rods mounted on each branch of the U-har and adjustable verticallyrelatively to the U-har; pivot blocks carried bythe vertical rods: a vertically adjustable stop connected with the plate; and corresponding scales on the rods and stop.
Intestimony whereof I have hereunto set my hand.
