Description
Technical Field
The present invention relates to a technique for dental prosthesis, and more particularly to a structure of a dental prosthesis for preventing atrophy of gum and/or alveolar bone.
Background
From clinical statistics, the gingival atrophy rate is as high as 78% on average. In other words, there are 8 people with gum atrophy problems per 10 people. Slight gum atrophy, possible gum bleeding, sensitive tooth root. The severe atrophy causes the loosening of teeth and harms the health of the surrounding teeth.
However, there are many reasons for causing gingival atrophy. Generally speaking, oral hygiene is generally poor, so that dental calculus and dental plaque stimulate gums to cause swelling, inflammation and other conditions. Of course, the mild condition of gingival atrophy can be improved by the hygiene of the oral cavity. However, severe cases of atrophy must be improved by means of gum transplantation or other surgical procedures. This form of improvement is inexpensive, requires a professional physician to perform the recovery by surgery, and is very laborious or painful.
In addition, the drawback of tooth loss is usually remedied by using artificial teeth. According to the oral health survey report of 2015-2016 in Taiwan Weifu department of China, nearly six adults in Taiwan have a pair of false teeth in their mouths.
As shown in figure 5, a fixed dental prosthesis 70, consisting of two braces 71 connected to a tooth 72, is adapted to fit in a row of real teeth 92 with a missing tooth. The two braces 71 are fitted over and adhered in the direction of arrow 73 to a set of molar teeth 96, the set of molar teeth 96 being generally ground from the real teeth 92 on either side of the edentulous portion 94, bridging the support teeth 72 to the edentulous portion 94 of the gum 90. Therefore, the fixed prosthesis 70 is also called "dental bridge".
In fig. 6, a pair of removable dentures 80 form a row of composite resin or plastic-steel die-cast teeth 84 on a tooth flesh 82 made of acrylic resin. The removable denture 80 is adapted to fit a gum 90 lacking a plurality of real teeth, the gum 90 securing one or more connectors 86. The coupling 86 may be a metal clasp, hook or magnet for engaging the movable denture 80 to impart a chewing function to the upper jaw to engage the lower jaw.
In either the fixed or movable type, the top of the denture will massage the gums 90 but will not stimulate the alveolar bone. When the alveolar bone is not used for a long time, the alveolar bone is easy to shrink, and the using state of peripheral real teeth is affected.
In order to solve the above problem, taiwan patent No. M536040 discloses a gingival biting sheet, which can fill up the gap between the upper and lower rows of teeth during occlusion of the upper and lower jaws, stimulate gums to prevent atrophy or loose and soft teeth.
Secondly, taiwan patent No. M569615 discloses an oral care device, which is configured with a driving unit in a body, and the driving unit is connected with a mouthpiece brush head through a transmission rod, the mouthpiece brush head has a plurality of layers of bristles, and the bristles clean teeth in the oral cavity and massage gums or gums.
In addition, the oral cavity and gum massaging device disclosed in taiwan patent No. I546069 provides a vibrating wall for biting the upper and lower rows of teeth, and the vibrating wall is driven by a micro motor to generate a certain vibration amplitude, so as to massage gums and stimulate blood circulation, thereby achieving the purpose of maintaining the health of oral tissues.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a new construction of denture, main aim at: the single-layer structure is disposed between the denture and the gum, and has a physical massaging effect on the gum and can suppress atrophy of the gum and/or alveolar bone.
In order to achieve the above object, the dental prosthesis of the present invention comprises: one massage structure is a single-layer structure body between the false teeth and the gum, and has a physical massage effect on the gum; one release structure is a single-layer structure between the denture and the gingiva, and has an inhibitory effect on atrophy of the gingiva and/or alveolar bone.
Wherein, this massage structure lets the gum receive appropriate stimulation, drives the blood circulation and the hyperplasia of gum meat, and under the stimulation of a period of time, lets atrophic gum obtain gradually and improves. Further, the release structure controls the release of the drug having the effect of suppressing the atrophy of the gum and alveolar bone, and produces a synergistic effect with the massaging of the gum. Of course, such inhibitory drugs act on the edentulous area of the gums while protecting the surrounding teeth, ultimately promoting overall dental health.
Specifically, the massage structure is a single-layer structure body made of rigid materials, elastic materials or rigid and elastic materials mixed in proportion. The massage structure is attached to the part of the movable false teeth (or dental bridges) contacting the gingiva, and can achieve the massage effect when the patient naturally bites. The composition of the massage structure can be adjusted according to different requirements of patients, such as: the degree of alveolar bone atrophy or the density of bone mass. In addition, the massage structure can be designed to effectively massage the gum with specific structures, such as: at least one regular or irregular protrusion.
In an embodiment, the drug released by the release structure includes, but is not limited to, drugs for inhibiting gingival and/or alveolar bone atrophy, for example, drugs for promoting blood circulation, having antibacterial effect or simultaneously containing multiple effects, all of which belong to the release range of the release structure. Therefore, the releasing structure is matched with the massage structure to generate the synergistic effect of combining medicines with massage on the oral health, thereby achieving the comprehensive protection function. In addition, the release structure may control the rate of drug release through one of the following mechanisms: a microneedle type release mechanism, a material adjustment type release mechanism, a pressure or temperature control type release mechanism, an electromagnetic wave or ultrasonic wave type release mechanism.
In brief, the microneedle type release mechanism is a mature technology, is selected from one of a solid type microneedle, a coating type microneedle, a dissolving type microneedle and a hollow type microneedle, and utilizes a fine needle body with the length less than 0.1 cm to penetrate through the skin surface layer for drug release. The pressure-type release mechanism releases the drug by pressure generated by the biting action. The temperature-controlled release mechanism utilizes body temperature to control the release of the drug. As the name suggests, the material-modulated release mechanism may utilize material composition to modulate the drug release rate. The electromagnetic wave type release mechanism releases the drug by means of electromagnetic waves. For the ultrasonic release mechanism, ultrasonic waves are used to release the drug. Therefore, according to the atrophy degree of the gingiva and/or alveolar bone of a patient, the release structure can adjust the release amount of the medicament to achieve the optimal treatment effect.
To sum up, the utility model discloses a false tooth structure possesses following function or advantage:
firstly, the massage structure and the release structure are directly combined with the movable false teeth (or dental bridges), so that the treatment effect is achieved in daily life working and rest time, the appearance is not influenced, and the time is not wasted in wearing.
Secondly, the cost of the tooth reduction operation is high, and only the beauty can be maintained, but the effect of root treatment is not available. However, the dental prosthesis structure of the present invention is worn in the oral cavity, which improves the health of the gum and/or alveolar bone of the edentulous portion and protects the health of the whole teeth.
Thirdly, the artificial tooth structure of the utility model combines the dual effects of physical massage and drug therapy.
Fourth, the utility model discloses a denture structure simple to use, the product preparation is cheap, and the result is excellent moreover.
To further clarify the objects, features and advantages of the present invention, one or more preferred embodiments will be described in detail below with reference to the accompanying drawings.

Detailed Description
Figure 1 is a layout view showing a first embodiment of a dental prosthesis 10, which may be a removable dental prosthesis or a portion of a bridge, attached to the outside of the surface layer 91 of the gum 90. Defining the prosthesis 10 facing the gingiva 90 is a contact surface 12, and a massaging structure 20 and a releasing structure 30 are attached to the contact surface 12 by adhesion means.
In the figure, the massage structure 20 is a single layer structure between the dental prosthesis 10 and the gum 90, and the single layer structure is made of a rigid material, an elastic material or a mixture of rigid and elastic materials in proportion. The massaging structure 20 has a main body 22 for attaching the recess of the dental prosthesis 10. The body 22 contacts the gum 90 in cooperation with the contact surface 12 of the dental prosthesis 10 during occlusion of the upper and lower jaws, providing a physical massaging effect. The massaging structure 20 further has at least one protrusion 24, and the protrusion 24 is formed on the front surface of the main body 22 to relatively increase the massaging effect of the main body 22 on the gum 90.
In this embodiment, the releasing structure 30 is also a single-layered structure between the dental prosthesis 10 and the gingiva 90, which is independent of the single-layered structure of the massaging structure 20, for suppressing the atrophy of the gingiva 90 and/or the alveolar bone 93.
In some embodiments, it is possible that the relief structure 30 is combined with the massage structure 20 as a single layer structure.
In the figure, the release structure 30 is a dissolving type microneedle, which includes: the drug-grade micro-needle comprises a carrier 32 and more than one micro-needle 34 which are made of a medical-grade high molecular material and a plurality of low molecular additives, and a group of particles 36 contained in the micro-needles 34, wherein the group of particles 36 are powder particles for inhibiting gingival atrophy and alveolar bone atrophy, promoting blood circulation and/or antibacterial drugs.
Fig. 2 is a reference view showing that the microneedles 34 passing through the surface layer 91 are swollen or dissolved at the gum 90, gradually releasing the set of particles 36. With diffusion, the set of particles 36 enters the gingiva 90 and/or alveolar bone 93.
Figure 3 shows a second embodiment of the implant 10, which is substantially identical in construction to the first embodiment, with the difference that: the release mechanism 40 is formed by a bladder 42 enclosing a plurality of particles 44 that together form a compression-type release mechanism. In the figure, the releasing structure 40 and the massaging structure 20 are of a single-layer structure different from each other.
During occlusion, as shown in figure 4, the denture 10 exerts a pressure on the pouch 42, causing the pouch 42 to rupture. The greater the pressure, the longer the opening of the pouch 42, the faster the release rate of the set of particles 44, which diffuse through the surface layer 91 into the gums 90 and/or alveolar bone 93.
