RU2214805C2 - Device for insulating teeth against saliva action when carrying out dental surgical interventions - Google Patents

Abstract

FIELD: medical engineering. SUBSTANCE: device has flexible plate 1 having two lateral radially divergent symmetric strips 2. Plate 1 is a circle or is shaped as shown in the application document. Lateral radially divergent symmetric strips 2 widen with the distance from the center. Strip thickness is thinned in the upper part beginning from the circle for being introducible into interdental spaces on both sides of a tooth, the rest being thickened to enable one to move and fix lip in lifted position. EFFECT: enhanced effectiveness in repairing tooth surface; high quality single use saliva protection article. 2 dwg

Description

 The invention relates to medicine, namely to the field of dentistry.

 Dental manipulations in the treatment, aesthetic restoration and prosthetics of teeth should be carried out in isolation from a humid environment.

 When restoring teeth with composite materials, fixing tabs, onlays, veneers, crowns, the patient is forced to keep his mouth open for some time. In this case, reflex closure of the mouth often occurs or the tongue accidentally touches the restored surface of the tooth, which subsequently leads to undesirable consequences (impaired fixation, chips of restoration).

 Given the above, in medical practice, a number of materials and tools are used to isolate teeth from saliva.

 The use of rubber sheets with raberdam is a reliable protection of the working surface of the restored tooth from moisture in the oral cavity and from accidental contact with the tongue (1, 2).

 A device for isolating saliva during dental interventions is known, which protects the surface of the restored tooth, made in the form of an elastic plate with two side radially diverging symmetrical strips (3).

 But due to the difficulty of fixing rhabderdam in the oral cavity and the large number of expensive tools for carrying out this procedure, raberdam is not always used in dental practice.

 The technical result - the creation of a public, disposable device that protects the restored tooth surface from moisture in the saliva when you touch it with your tongue, lips or accidentally closing your mouth.

 This goal is achieved by a device consisting of disposable plates fixed in the interdental spaces on both sides of the restored tooth and protecting the tooth from touching with the tongue, lips or accidental closing of the mouth.

 In FIG. 1, 2 presents the inventive device, consisting of two plates. FIG. 1 is an elastic celluloid plate (1), made in the form of a circle 0.2 mm thick, 30 mm in diameter with two L-shaped lateral, symmetric radially diverging strips 8 mm wide, 20 mm long (2). The section of the L-shaped strip at the point of attachment to the round plate (3) is thinned in its upper half to 0.06 mm, and its distant rectangular part (4) is thickened to 40 mm.

 FIG. 2 differs from the plate 1 in that the central part has an elongated shape (5) instead of a circle.

 The plate (Fig. 1) is used on the central teeth of the upper or lower jaw with a low alveolar ridge or a flat hard palate, as follows.

 Celluloid plates are inserted by the thinned part of the L-shaped radial plates into the interdental spaces on both sides of the tooth on which the dental intervention is performed. If the plate is not firmly fixed between the teeth, then it can be fixed using wooden or plastic wedges or used to fix adjacent teeth. The celluloid plate is made of transparent material in order to more conveniently select the color of the tooth being restored, it is located on the palatine or lingual side of the tooth being restored, reliably protects it from touching with the tongue and from accidentally closing the mouth. The thickened parts of the L-shaped radial plate push and lift the upper lip, hold it in a raised position, preventing it from touching the teeth and creating a better overview for the dentist. If the plate is used on the lower jaw, then in this case the lower lip is moved away and reliable protection is created from the lower lip touching the teeth.

 The protective plate (figure 2) is used with a high hard palate. Its application is the same as the plate (figure 1).

 The proposed device, consisting of two plates, is used in therapeutic and orthopedic dentistry to protect the dry surface of the tooth on which dental interventions are performed.

The technical advantages of the new protective device are as follows:
- allows you to easily and quickly use the device on all groups of teeth;
- It is a reliable protection against accidental contact with the tongue and lips;
- protects the dry surface of the tooth from accidentally closing the mouth during prolonged dental interventions;
- increases the review of the restored tooth.

Claims (1)

 A device for isolating teeth from saliva during dental interventions, protecting the surface of the restored tooth, made in the form of an elastic plate with two laterally radially diverging symmetrical strips, characterized in that the plate is made in the form of a circle or in the shape shown in FIG. 2 poses 5, and the lateral radial symmetrically diverging strips are made expanding as they move away from the center, while the thickness of the strips, starting from the circle, is thinned in the upper part to accommodate it in the interdental spaces on both sides of the tooth, and the remaining part is thickened to allow shifting and fixing lips in a raised position.
