COMBINATION DENTAL APILIANCE Application filed March 9, 1929. Serial No. 345,708.

This invention relates to the class of apparatus employed in the performance of dental and surgical operations in the. mouth, and more particularly to a combination dental 5 appliance for facilitating and simplifying the work of the operator.

It has been the object of my invention to provide a combination dental appliance of the character set forth, combining into a compact and efficient arrangement the essential appliances, i. e., the saliva ejector, the cotton roll holder and tongue retractor, as'are at present utilized while operating in the mouth- A further prime object of this invention has been the provision of an electric lighting means, incorporated in the appliance, that would permit the operator to dispense with the elaborate lighting means now used at the dental chair. Furthermore, the employment of my combination appliance eliminates entirely the need for dental rubber dam.

With the use of the saliva ejector, cotton roll holder, tongue retractor, etc., as is the case at present, it is a requisite that the dental op-' erator has the aid of an assistant in'the manipulation of these appliances. With the use of my combination appliance the services of this assistant may be dispensed with.

An important feature of my invention resides in the provision of a means for applying a cotton roll in the bucco maxillary section of the mouth, to; absorb the saliva from the parotid glands exuded through Stensons duct, in addition to the cotton rollsprovided 55 for the lingual and labial portion ofthe 40 plicity of construction of my mandible. p

While the functions of the aforesaid separate appliances have been combined-into this improved combination appliance, the s1mappliance compares most favorably with that of any of the individual appliances it supplants. Moreover, the construction and arrangement of the members of this combination appliance perin mits a readible sterilization of any of the inrangement and combination of'parts, the estion appliance in perspective.

Figure 4 is an elevational fragmentary View of the right mouth member of the appliance partly in section.

Figure 5 is a View of the central mouth member of the appliance in perspective;

Referring to the drawing, more particularly Fig. 1, I have shown the chin-plate 1 as the means for supporting my appliance to the head. This chin-plate ,1 is shaped to conform to the contour of theunder portion of the chin, and made preferably of a thin stiff metal. In the drawingothe chin-plate 1 has been shown rectangular in form for simplicity, but may be extended to conform to any portion of the head. The chin-plate is provided with the openings 2, for insertion of the conventional head straps, when itis desired to support the appliance more positively under the chin.

g The under side of the'chin-plate 1 termithe arm 3 with arotatable movementto accommodate either the right, central or left mouth member in the mouth. Thepart1cular mouth member utilized lslield injposition,

against horizontal movement, by tightening of the clamping nut 5 againstthe arm 4. V

This combination appliance 7 has been shown in the drawing provided with three individual. mouth members, i. e.,' a right mouth member, illustrated in. Fig. 3, to be used when operating on" the right side of the mouth posteriorly, a central mouth member, illustrated in Fig. 5, to be used when operating in the anterior section of the mouth, and

a left mouth member, illustrated in Fig. 1, to be used when operating on the left side of the mouth posteriorly. Each of the three month members comprises a double tubular limb construction, the two lengths of tubing, or limbs, being rigidly joined for a section of their length by solder, or any oth r suitable means. One limb of each mouth memher is composed of a length of tubing shaped to conform to that section of the mouth with which it cooperates, and is adapted to convey the saliva from the mouth to the saliva outlet hose 6. The other limb of this mouth member comprises a second length of tub ng, correspondingly shaped to suit that section of the mouth wherein it is disposed, and provides the electric lighting means at the desired location in the mouth.

Referring to Fig. 1, the saliva ejecting limb 7 of the left mouth member has been shown formed of a vertical section, bent over substantially horizontal at the top where itenters the mouca, and terminating into a U shaped sector closed at the end. The ll shaped portion of this limb 7 is fo med to lay POSlLlOllGCl on the ling al mandible. In this pos ion the sa" lecting in this part of the month is era through the openings 8, three suca openings being illustrated reference bein iad to Fig. 2, situated in the under portion of the ll sector near its extremity. It has been the object in terminating the upper extremity of the right and left mouth members in form of U sectors, to provide for the insertion of one or more cotton rolls, of the variety ordinarily used in mouth operations, to be disposed and retained between the arms forming the U shaped sector.

The limb 9 providing the electric lighting facilities, reference being had to Figures 1 and 4:, extends likewise vertically for a portion of its length, and at the top, where it enters the mouth. is bent substantially horizontal. The vertical portion of the limb 9 is rigidly joined. by solder or any other suitable means, to the vertical portion of the limb 7, forming therewith a single unit. The horizontal portion of the limb 9, where it enters the mouth. forks away from the hori zontal portion of the limb 7, so that it is disposed along the labial portion of the mandible. Ateach extremity of the limb 9 is permanently mounted an electrical receptacle, or rather the base part thereof. with the wires extending through the hollow of the tubing limb. Both ends of the limb 9 are sealed water-tight.

In the upper receptacle 10 is plugged the electric light 11 furnishing: the illumination and directed in the mouth as required. To the receptacle 12, mounted at the lower e tremity of the limb 9, is plugged in the elec tric connection leading to the source of electric current. Should it prove desirable a rheostat may be readily connected between the receptacle 12 and the source of electric supply.

In addition 10 supporting the electric lighting means for the illumination of the mouth, the limb 9 also acts as the means for retaining cotton rolls, one or more as required, on the labial portion of the mandible. The adaptability of the limbs 7 and 9 to function as retainers of cotton rolls in the mouth, dispenses with the necessity for use of the cotton roll holder. as is ordinarily employed for operations in this portion of the mouth.

In the general class of cotton roll holders at present in use, there is no provision made for damming and absorbing the saliva issuing from the parotid salivary glands through Stensons duct. In my combination appliance l have provided the arm 13, rem0vably mounted to the upper extremity of the limb 9, and the shelf 1 1 rigidly joined thereto. This shelf 1% is fitted to support one or more cotton rolls in the area of the mouth surrounding the outlet of Stensons duct, to dam and absorb the saliva discharged therefrom.

The arm 13, referring to Fig. 4, has been here shown comprised of a tubing element, fixedly held in a sliding lit connection with an extension of the upper extremity of the limb 9. To remove this cotton roll arrangement it is merely necessary to slidably disengage the arm 13 from the extension of the limb 9.

The right mouth member, illustrated in F 3, is similar in construction and functionability of the parts, to the left mouth member as described hereinbefore. The salira. ejector limb and the limb 9 providing the electric lighting for the right mouth member, are siiaped to be disposed in their rcspective locations on the right side in the mouth, corresponding to the similar parts of the left mouth member.

In the central mouth member. reference being had to Fig. 5, the saliva ejector limb 15 comprises a. vertical length of tubing bent ver substantially horizontal where it enthe mouth, and there branching oil into a right and left sector, each sector terminating in a closed end. Each of ti sectors of the limb 15 is shaped to conform to the structure of the mouth it traverses, with the ends bent downwards to form a cradle for the tongue. Towards "he cxtremity of each sector are positioned the openings 8 in the tubing. to drain the saliva collecting in this part of the mouth. The sectors of the limb 15 too act as the means for retaining; cotton rolls, both lingually and labially, in this portion of the mouth.

The limb 16, referring to Fig. 5, furnishing the electric lighting means in the month, an-

teriorly, comprises a vertical length of tubing bent over substantially horizontal where it enters the mouth, "and from there on following in shape the left sector of the limb 15. The limb 16 has been here indicated as fixedly joined to the limb 15, by solder or any other suitable means, throughout the length of this sector of the limb 15. This limb 16 containing the electric lighting wires is sealed watertight at both extremities, and has mounted thereon the base part of the light receptacle at the upper end, and the base plate of the receptacle receiving the electric source connections at the lower end. Should it prove desirable the upper portion of the limb 16 may be shaped to just as readily follow the shape of the right sector of the saliva ejector limb 15. v

In each instance, the vertical length of saliva ejector limb has been shown greater in length than that of the limb supplying the electric lighting means. That portion of the vertical length of the saliva ejector limb extending down beyond the other limb, is adapted to be supported in a cooperatively positioned opening in the arm 4:, in a slidable fit, reference being had to Figures 1 and 2. By this arrangement the limbs 7 and 9, also 15 and 16, may be moved up or down, or rotated, to readily insert any of the mouth members in the mouth, or remove them from the mouth. To hold the particular mouth member utilized, in a desired fixed position in the mouth, the set screw 17 is employed locking the mouth member in the required position. I

he preferred material for the construction of the mouth members of my combination appliance would be brass, but hard rubber or a composition material may be substituted therefor, in whole or in parts.

While I have described and illustrated a preferred embodiment of my invention hereinbefore, I would have it understood that I do not limit myself to the details of construction and arrangement of parts set forth and shown, but reserve the privilege to make modifications and changes within the spirit and scope of the claims appending.
