Description

{DENTAL FIXTURE FOR TOOTH HEMOSTASIS}

More particularly, the present invention relates to a hemostat for hemostasis of a tooth, which can fix a suture by covering a nearby tooth with a cotton so as not to separate the cotton for hemostasis after tooth treatment.

At the time of extraction, the blood vessels passing through the teeth rupture and bleeding occurs. In order to prevent the bleeding from being overcome and to regulate the amount of blood to be held in the mouth, the dentist bites the cotton. However, it is difficult to hemorrhage because it is easy to get rid of cotton wool, and if it is worn for a long time, the jaw joint may become unreasonable and health problems may occur.

In addition, Korean Patent Laid-Open No. 10-2012-0080700 discloses a technique related to a cotton to be fixed to an extraction site after tooth extraction. This technique includes a spring that brings the claws and the claws in close proximity to the claw to secure the crotch to the crotch region so that the crotch is fixed to the gums so that the crotch is fixed more strongly than the crotch to hold the crotch. However, this technique has a problem that teeth are deformed by applying pressure to the teeth on both sides of the extraction site by the above-mentioned clamp and the spring.

Therefore, there is a need for a fixation device for the hemostasis of the teeth, which can keep the jaw joints healthy while keeping the wool stable.

When the amount of the plant extract is less than 0.03 part by weight based on 1 part by weight of the shape memory polymer powder, the antibacterial and antifungal effect may be insufficient because the proportion of the plant extract is too low. When the amount is more than 0.03 parts by weight, The toxicity contained in the composition may cause side effects.

Hereinafter, the results of electromyographic analysis by chewing exercise after wearing the dental bleeding for dental bleeding when the dental bleeds for dental bleeding according to the present invention are used will be described in the following examples.

A. EMG analysis

The EMG analysis is a method of measuring the fatigue of the joint, and the jaw muscle fatigue when the dental bleeding for the tooth hemostasis of the present invention is used and the fatigue of the jaw muscle when the dental bleeding for a general dental bleeding are used are examined. Respectively.

The electromyogram was performed for 60 seconds while maintaining the muscular strength corresponding to 30% MVC while maintaining the jaw joint posture. Among them, 5 seconds after the start of the experiment and 5 seconds before the end of the experiment were used and 50 seconds were used. The muscle signals obtained by the measurements were calculated as MPF (mean power frequency) values through FFT (Fast Fourier Transform). 50 subjects were allowed to maintain a commonly used dental bleeding blood for hemostasis for 24 hours, and the MPF value of the jaw muscles was measured. Next day, 50 subjects of the same experiment were given dental bleeding for 24 hours The MPF values of the jaw muscles were measured after use. In order to compare the calculated MPF, normalization was performed based on the MPF value at the start of the experiment. Examples of changes in MPF value obtained through normalization over time are shown in Table 1 and FIG.

Time (hours) 4 8 12 16 20 24 Normal
Temporary teeth -8 -10 -13 -16 -21 -25 The present invention
Tooth bleeding
Zebrafish -One -One -2 -3 -3.1 -3.5

Generally, the greater the magnitude of the measured MPF absolute value, the greater the degree of muscle fatigue. In addition, when the muscle is continuously used for 1 to 2 hours at an MPF value of -20 or less, pain may occur in muscles and joints.

Specifically, when the above-mentioned experiment is performed, it can be seen that the absolute value of MPF is greater than 20 for 4 hours when using a hemocyte for general dental bleeding, and the absolute value of MPF does not exceed 3.5 when the present invention is used. It can be seen that there is no difficulty in the jaw joint.

In addition, it can be seen that the measured jaw muscle MPF initially decreases in absolute value and then gradually increases. It is considered that as the fatigue of the jaw muscles increases over time, the pressure can not be maintained constantly.

According to the solution of the above-mentioned problems, the present invention can provide a dental hemostat for dental bleeding which does not damage the jaw joints and the teeth by immobilizing a cotton to be wiped at the extraction site after extraction.

In addition, the present invention can provide a dental hemostat for a dental bleeding which is deformable according to a tooth shape.

In addition, the present invention provides a hygienic dental hemostatic composition which is composed of a non-toxic shape memory polymer, polycarbonate, silicone, silicone composite material, or polyether ether ketone (PEEK) .

In addition, the present invention can provide a universal dental bleeding device capable of daily life after extraction and being usable regardless of the extraction site.

In addition, the present invention has an effect of protecting an extraction site so that inflammation due to a foreign substance does not occur at an implant extraction site.

In addition, the present invention can produce dental bleeding for dental bleeding, which can minimize the inconvenience in life without deteriorating the beauty of the teeth due to tooth defect after extraction of the front teeth.

Further, the present invention has an effect that it is easy to adhere to the teeth at the oral temperature by using the shape memory polymer material, and the extraction site can be effectively protected.
