Description

interdental cleaning stick

technical field

The utility model relates to the field of tooth cleaning products, in particular to a tool for cleaning food impaction on the adjacent surfaces of teeth and the gingival ends of implanted dentures.

Background technique

With the progress of periodontal atrophy and periodontal disease, adjacent spaces appear between teeth, the abutment is not close, and even gaps appear. The immediate consequence is food impaction after eating. Food impaction can lead to gingival pain, inflammation, swelling, and papillitis of the gums. If the food impaction is not resolved for a long time and the patient develops tolerance to this impaction state, neglecting to clean it can lead to dental caries in the neck of the tooth, and then the pulp Inflammation, apexitis, apical abscess and a series of periodontal diseases. Therefore, people are badly in need of a kind of daily tool that cleans teeth.

The promotion and application of implant dentures in clinical work is becoming more and more extensive. Around the abutment of the implant denture, the artificial crown is usually in contact with the gums, and food retention and impaction will inevitably occur. A cleaning tool for cleaning the gingival end of the implant crown is also needed.

The most familiar tool for solving food impaction in daily life is the toothpick. But dentists do not recommend using toothpicks. Because the toothpick is linear and cannot match the radian of the teeth, forcibly using the toothpick will damage the gums and cause further shrinkage of the gums (defect one). For the gingival end of the implant crown, the toothpick is helpless, and cannot be inserted between the gum and the implant crown (defect 2). Another tool for tackling food impactions in teeth is flossing. People can freely cut the floss length according to the length of use. Floss works well in the anterior area but not in the posterior area. Because the dental floss is wound around the fingertips to clean the teeth, the size of the oral cavity is limited, and the fingers of both hands are inconvenient to be stretched into the oral cavity, which also does not meet the hygienic norms (defect three). There are also various brands of dental floss picks on the market, but they are all linear, which is very inconvenient for cleaning the posterior teeth. Especially for right-handers or left-handers, the use of straight-line dental floss picks can only be limited to facilitate the cleaning of one side of the back teeth (defect four).

According to page 517 of the sixth edition of "Prosthodontics" published by People's Health Publishing House, food impaction can be divided into vertical type, horizontal type, and a mixture of both. The horizontal type and the mixed type are mostly due to physiological gingival recession, interdental papilla destruction or disappearance, resulting in interdental space exposure. These two types of food impaction often cannot be cleaned out by dental floss alone, and need to be cleaned with a probe-like cleaning tool (defect five).

Chinese Invention Patent Publication CN104013474A (announcement date: 2014.09.03, invention name: dental floss stick for dental care), utility model patent CN201420300487 (announcement date: 2014.11.05, invention name: dental floss stick for dental care) and appearance design CN303022187S (announcement date: 2014.12.03, invention name: dental floss stick) discloses that the front end of the dental floss stick is dental floss, and the rear end is a handle, but they are all linear, which is very inconvenient for cleaning the back teeth. Defects 3, 4, and 5 cannot be resolved by design. The latter design can solve defect five, but cannot solve defect three and defect four equally.

Visible, existing tooth cleaning tool still can't effectively solve five big defects of cleaning teeth simultaneously.

Contents of the invention

Aiming at the above-mentioned defects that cannot be solved at the same time, the purpose of the invention of the utility model is to produce a tooth cleaning tool that can simultaneously clean up vertical food impaction, horizontal food impaction and mixed food impaction.

In order to realize this object of the invention, the utility model has adopted following technical scheme:

An everyday tool for cleaning the adjacent surfaces of teeth and the gingival end of implants. It includes a U-shaped dental floss holder, dental floss near the bottom ends of the two feet of the dental floss holder, a middle rod connected to the dental floss holder in a T shape, and a semicircular probe at the end of the middle rod. The four-part structure is integrally formed.

Preferably, the effective height between the top of the dental floss holder and the dental floss is 12-14 mm, which is convenient for cleaning the gingival end of the implant crown.

Preferably, the width between the two feet of the dental floss holder is 16-18mm, which is convenient for pulling back and forth to clean the crown, buccal and lingual.

Preferably, the dental floss holder is connected to the middle rod in a T shape, and can be inserted from the front of the oral cavity, so that the left and right rear teeth can be cleaned conveniently. And the connection angle is 100°-110°, which is convenient for dental floss to be pressed into the interdental space between teeth, which is in line with artificial mechanics.

As a preference, the length of the middle rod is 50-55mm, which is convenient for use without extending the hand into the oral cavity, but can clean the teeth to the end. The shape of the middle rod is flat, and the grips at both ends have a textured design, which is good for gripping without slipping.

As a preference, the semicircular probe at the end of the middle rod has a span of 15-17mm, a semicircular height of 10mm, a straighter 8mm at the front end, a circular cross-section that becomes thinner as it gets closer to the tip, and a cross-sectional diameter at 8mm from the tip of about 1.5mm. Gradually migrate to a sharp tip, which is beneficial to clean horizontal food impaction and mixed food impaction.

Preferably, the dental floss holder, the middle rod and the semicircular probe are all plastic products, which are convenient for overall molding and low in price, and are conducive to popularization.

The interdental space cleaning stick of the above technical solution adopts the design that the dental floss holder and the middle rod are connected in a T shape, and the end of the middle rod is formed into a semicircular probe. Compared with the existing technology, the user can hold the interdental cleaning stick and operate it outside the mouth to clean the food impaction in the molar area on the left and right sides smoothly. Whether it is right-handed or left-handed, it can be operated smoothly without handles into the mouth. If the gap between the teeth is tight, use the dental floss device at one end; if there is a lot of food impaction, and the food is embedded in the gum between the two teeth, you can use the probe at the other end. The probe can also clean the soft dirt on the buccal and lingual sides of the teeth without depositing and forming dental calculus. This interdental space cleaning stick can basically solve all types of food impaction.
