Dental isolator for protecting the tongue and cheek during dental treatment

Abstract

An isolating retractor instrument to protect a tongue and a cheek of a patient during a dental treatment. The isolating instrument includes a first isolating pad (A) for the tongue, and a second isolating pad (B) for the cheek. Each of the first isolating pad and the second isolating pad having a first (1) layer contacting and adhering to oral tissue, the first layer including an absorbing material for absorbing liquids, a second layer (2) including a fast-absorbing material which absorbs the liquids and holds the liquids, a third layer (3) adjacent the second layer, the third layer (3) including a reinforced, flexible material for supporting and stabilizing a respective isolating pad, and a fourth layer (4) including a reflective, smooth, flexible, and liquid-isolating material positionable to face a plurality of teeth of the patient. A flexible tape connects the first isolating pad and the second isolating pad.

2. The isolating instrument according to claim 1, wherein the rounded edge comprises the first layer (1) adherable to the soft tissue and configured to absorb the liquids, the first layer at least partially surrounding an inner layer (5) comprising a material unable to absorb the liquids, the inner layer providing support and smoothness for the rounded edge.

3. The isolating instrument according to claim 2, wherein the inner layer (5) comprises a sponge silicon.

4. The isolating instrument according to claim 1, wherein the first isolating pad (A) comprises a convex tip configured to follow a profile of an internal oral cavity of the patient for providing protection to the tongue.

5. The isolating instrument according to claim 1, wherein the second isolating pad (B) comprises a convex internal tip and a concave external tip opposite the convex internal tip configured to follow a profile of an internal lip border of the patient.

THE DETAILED DESCRIPTION

(8) The idea of this invention lies in a simple and creative instrument with two flexible isolating pads connected with a flexible and folding tape. The two isolating pads entered inside the mouth in the place that should be treated, it allows the patient to close and open his mouth easily, and it uses for both sides of the mouth the right and left.

(9) FIGS. 1 through 6 illustrate a retractor for protecting the tongue and cheeks during dental treatment. The first pad is adapted as an isolating covering for protecting the tongue (A), and the other pad is adapted as an isolating covering for protecting the cheek (B). Both isolating pads (A) and (B) have rounded edges (FIG. 2 and FIG. 4) to provide the protection for the mouth membrane from bruises and injuries.

(10) In FIG. 1, the isolating pad (A) characterized in that has convex tips as shaped the internal oral cavity for giving full protection to the tongue, while the isolating pad (B) characterized in that has a convex internal tip and a concave external tip shapes at the internal lip border. As illustrated in FIG. 2 and FIG. 4, both isolating pads (A) and (B) characterized by having two sides. The internal side (1) adapted to adhere to the oral tissue, it is made of a material (such as cotton tissue) allows to adhere to oral tissue and helps to absorb the saliva or water from the oral cavity so it can stabilize the instrument and prevent it from moving. The other side (4) external at the dental operating area which is front of the teeth, is made of a smooth cardboard and has a reflected color (like white) to helps for reflecting the light, and gives protection to the area from sharp dental instruments.

(11) FIG. 4 shows both isolating pads comprise of four layers. A first layer (1) which faces the mouth tissue is a thin layer of an absorbing material (like cotton) helps to adhere to the tissue and absorbs the saliva or liquids. A second layer (2) is a fast-absorbing material, it absorbs the saliva or liquids and can hold the fluids in a long time like the one used in diapers. Beside the second layer is a supportive layer (3) made of a reinforced flexible material (such as plastic) to support and stabilize the pad. Then a last layer (4) is a cardboard, which faces the teeth, is a smooth, a flexible, an isolating of the liquids and has a reflected color (like white). Each edge of the isolating pads is adapted to prevent the injuries of mouth tissue; it is a rounded and derive the supporting and stability from the extension of cardboard layer (4). These edges includes two layers; the first layer (1) is a thin absorbing material (such cotton) helps to adhere to the tissue and absorb the saliva or liquids, and the second layer (5) is a material which is unable to absorb the liquids or saliva (like a sponge silicon) to give the protection and stabilization for the isolating pad, smoothness for its borders.

(12) FIG. 3 and FIG. 6, the tape (c), connected the two isolating pads (A) and (B), is a flexible foldable extending from the inside of the first isolating pad (A) and connects the other one (B) to provide the supporting and stability for both. It characterized by smooth convex edges to prevent any bruises or injures to the oral soft tissue as shown in FIGS. 2 and 5. Its width characterized by suiting the internal jaw's width to ease opening and closing the mouth while dental treatment as shown in FIGS. 3 and 6.

(13) This instrument will have several sizes to suit the mouth of the children and adults. It is worth mentioning that everything similar either to explained here by figures or by description is meant to be under the invention.

(14) The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The described embodiments are to be considered in all respects as illustrative and not restrictive. Accordingly, the scope of the invention is indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalents of the claims are to be embraced within their scope.
