Abstract

<P>PROBLEM TO BE SOLVED: To provide a tooth protector with which a laryngoscope can be inserted into an oral cavity without giving a pain to a patient and which protects teeth of the patient from a shock of the laryngoscope. <P>SOLUTION: Using material having elasticity after shaping, the tooth protector (10) is produced to have a thickness according to the strength of an alveolar bone assumed about a part where the alveolar bone is weak in the oral cavity. The gum (23) at the part where the alveolar bone is weak and teeth (20, 21 and 22) kept by the alveolar bone are crowned with the protector to protect the teeth from the shock of the laryngoscope. The material having elasticity can be elastic impression material of a dental rubber quality. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a tooth protector, and more particularly to a protector in which a laryngoscope or the like can be inserted into the oral cavity without causing pain to the patient, and the patient's teeth can be protected from the impact of the laryngoscope.

  For example, when operating a patient with general anesthesia, a return tube is inserted into the trachea and anesthetic gas is administered, but when the return tube is inserted into the trachea, a laryngoscope needs to be inserted into the patient's mouth. Sometimes. In that case, there is a concern about a medical accident in which the laryngoscope accidentally hits the patient's tooth due to an emergency of surgery and the tooth is damaged.

On the other hand, mouthguards such as rugby, which are worn in the oral cavity during intense exercise and prevent teeth from being broken or damaged by impact or the like have been proposed (Patent Document 1, Patent Document 2, Patent Document 3). In such a mouth guard, an impression of the entire jaw and teeth in the oral cavity is collected, a mold is formed from the impression, and a mouth guard is manufactured using this mold and a thermoplastic material.

  The mouth guard described above is designed to protect the entire jaw and teeth, so when used for the purpose of protecting the teeth during surgery, the mouth becomes narrower and the laryngoscope is smoothly placed in the patient's mouth. It is difficult to insert and can be painful for the patient.

  In view of such problems, the present invention provides a tooth protector that can insert a laryngoscope into the oral cavity without causing pain to the patient, and that can protect the patient's teeth from the impact of the laryngoscope. The issue is to provide.

  Therefore, the tooth protector according to the present invention is manufactured in a thickness according to the strength of the alveolar bone assumed for the weak part of the alveolar bone in the oral cavity using a material having elasticity in the tooth protector for protecting the tooth, It is covered with the gum of the weak part of the alveolar bone and the tooth maintained by the alveolar bone, and the tooth is protected from the impact of the laryngoscope.

  A feature of the present invention is that the tooth protector is manufactured to have a thickness corresponding to the strength of the alveolar bone assumed for the weak part of the alveolar bone using a material having elasticity, and this tooth protector is used for the gum and the alveoli of the weak part of the alveolar bone. It is in the point that it was made to cover the tooth maintained by the bone.

  As a result, when the laryngoscope is inserted into the oral cavity, if the laryngoscope hits the tooth protector, the tooth protector will elastically deform and relieve the impact, so that the impact of the laryngoscope will be mistakenly applied to the tooth with weak alveolar bone That's not to say, and medical accidents such as tooth damage can be avoided.

  In addition, since the tooth protector covers the necessary part with the necessary thickness, the inside of the oral cavity is hardly narrowed, and the patient is not painful when the laryngoscope is inserted.

  The material having elasticity may be any material as long as it is made of a tooth protector and has elasticity when covered with teeth and alveolar bone, and is harmless to the human body, but considering the protection of the teeth, It is preferable to use a dental rubber elastic impression material, for example, an addition polymerization type vinyl silicon impression material.

  This tooth protector may collect the weak part of the alveolar bone and the impression of the tooth in advance of surgery and shape it using an elastic material. It may be applied directly to produce the required thickness.

  In the case of manufacturing at the time of surgery, it is preferable to use a dental rubber elastic impression material composed of a main agent and an auxiliary agent and used by mixing them.

  Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 and 2 show a preferred embodiment of a tooth protector according to the present invention. In the figure, the tooth protector 10 is placed on, for example, the middle incisor 20, the side incisor 21 and the canine 22 of the lower teeth whose alveolar bone has weakened, and the gums 23 of the respective teeth 20-22.

  The tooth protector 10 is manufactured using a dental rubber elastic impression material, for example, an addition polymerization type vinyl silicon impression material. The addition polymerization type vinyl silicon impression material is, for example, a base agent mainly composed of vinyl polysiloxane and silicon dioxide ( Main agent) and a catalyst agent (adjuvant) mainly composed of vinyl polysiloxane, silicon dioxide and platinum catalyst are used.

  Further, the tooth protector 10 is manufactured to have a thickness corresponding to the strength of the alveolar bone assumed for the alveolar bone of the lower incisor 20, the side incisor 21, and the canine 22 in the oral cavity.

  For example, the alveolar bone of the lower incisor 20 and the side incisor 21 is weak, and when manufacturing the tooth protector 10 that protects these teeth, a predetermined amount of a rubber elastic elastic impression material, for example, addition polymerization An equal amount of base agent and catalyst agent of the type vinyl silicon impression material are taken, mixed and kneaded (step S10).

  The impression material that has been kneaded within 1 minute 20 seconds after kneading, for example, the inner incisor 20 and the side incisor 21, and further the canine 22 and the gums 23 of each tooth 20-22. Next, it applies to the thickness according to the strength of the alveolar bone of the assumed central incisor 20 and side incisor 21 (step S11).

  When a predetermined curing completion time, for example, 3 minutes elapses after application (step S12), the tooth protector 10 shown in FIG. 2 is obtained.

  Since the tooth protector 10 can be manufactured on the spot in this way, for example, when a patient needs to insert a laryngoscope into the oral cavity during surgery, the lower incisor 20 and the side incisor with weak alveolar bone are cut off. The tooth protector 10 can be covered with the tooth 21 and the canine 22 and the gingiva 23, and even if the laryngoscope is mistakenly directed toward the middle incisor 20 and the side incisor 21 of the lower tooth, the tooth protector 10 receives the impact. By receiving and elastically deforming, the impact is reduced, the lower central incisor 20 and the side incisor 21 are protected from the impact of the laryngoscope, and the lower incisor middle incisor 20 and side incisor 21 are weakened by the alveolar bone. There will be no medical accidents that will break.

  In addition, there is almost no narrowing of the oral cavity, and no pain is given to the patient when the laryngoscope is inserted into the oral cavity.

  In the above example, the tooth protector 10 is manufactured at the operation site during the operation. However, the impression in the oral cavity of the patient undergoing the operation is collected, and the central incisor 20 and the side of the lower tooth whose alveolar bone is weakened. The incisor 21 and the canine 22 and the gingiva 23 may be formed, and the tooth protector 10 may be manufactured using the impression material described above.

  Moreover, although the tooth protector 10 which covers the middle incisor 20 and the side incisor 21 and the canine 22 and the gingiva 23 of the lower tooth has been described as an example, the same applies to the tooth protector which protects other lower teeth or upper teeth. Applicable to.

It is a figure which shows the manufacturing method of preferable embodiment of the tooth protector which concerns on this invention. It is a figure which shows the lower tooth equipped with the tooth protector of the said embodiment.
