Abstract
Description
Technical Field
[0001] This invention belongs to the field of medical devices, specifically a multifunctional device for repairing soft and hard tissue defects in the oral cavity. Background Technology
[0002] The soft tissues of the oral and maxillofacial region include the tongue, gums, lips, mucous membranes, skin, fat, and muscles. Due to their soft texture, they are also the most vulnerable to injury. The hard tissues of the oral cavity refer to hard tissues and organs such as teeth and jawbones, which can resist certain external forces, but can still be damaged by bacteria or violence, such as tooth decay, tooth fractures, and other defects.
[0003] In daily life, one of the most easily damaged soft tissues of the oral and maxillofacial region is the mucosa. When eating cold or hot foods, the oral mucosa is prone to damage. Common defects in oral hard tissues include dental caries and occlusal surface wear. Dental caries is caused by bacteria that demineralize the hard tissues of the teeth and decompose organic matter, resulting in discoloration, decalcification and softening of the hard tissues of the teeth, and the formation of cavities. Occlusal surface wear is often caused by poor chewing habits such as eating hard foods or bruxism.
[0004] Currently, patients with cavities or occlusal wear undergo dental fillings. However, if unhealthy lifestyle habits are not effectively changed after fillings, cavities and occlusal wear may still occur. Therefore, it is necessary to propose a multifunctional device for repairing oral soft and hard tissue defects. By constructing a caries inhibition model, an occlusal wear inhibition model, and a maxillofacial skin defect repair model, patients can use it daily to prevent and repair oral soft and hard tissue defects to a certain extent. Summary of the Invention
[0005] The purpose of this invention is to propose a multifunctional device for repairing oral soft and hard tissue defects. By constructing a caries inhibition model, an occlusal surface wear inhibition model, and a maxillofacial skin defect repair model, patients can use it daily to prevent oral soft and hard tissue defects and achieve multifunctional repair effects.
[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a multifunctional device for repairing defects in oral soft and hard tissues, comprising a hollow gingival sleeve, on which a plurality of hollow tooth sleeves are integrally formed.
[0007] The dental crown contains several fragmented balls, which are filled with casein phosphopeptide calcium phosphorus complex; the dental crown has through holes for the casein phosphopeptide calcium phosphorus complex to flow out.
[0008] The dental brace is integrally molded with several occlusal parts, and the wear resistance of different occlusal parts is different.
[0009] The sidewall of the dental brace has an integrally formed elastic skeleton, which is composed of several hollow and interconnected parallelogram supports; the elastic skeleton has several small holes; the center of the elastic skeleton has an integrally formed storage part, which is connected to the elastic skeleton and is filled with anti-inflammatory drugs.
[0010] Furthermore, the wear resistance of the interlocking parts depends on the density of their building materials.
[0011] Furthermore, the method for constructing a multifunctional device for repairing soft and hard tissue defects in the oral cavity includes the following steps:
[0012] Step 1: Construct a dental brace model; Create a 3D model of the patient's teeth using an oral scanner, and then construct a dental brace model adapted to the patient. The dental brace model includes the gum line and the tooth line.
[0013] Step Two: Assess the condition of tooth and facial skin defects; By taking pictures of the patient's oral cavity, the doctor can assess the condition of the patient's tooth and facial skin defects; The criteria for assessing tooth defects are: the location of the cavities and the degree of wear on the occlusal surface; The criteria for assessing facial skin defects are: the degree of facial skin damage.
[0014] Step 3: Construct a caries suppression model: Based on the dental brace model, construct a caries suppression model according to the location of the caries. Specifically, construct a fragmented sphere inside the dental brace where caries are present. The fragmented sphere is filled with casein phosphopeptide calcium phosphorus complex. Make an opening on the side wall of the dental brace near the caries defect.
[0015] Step 4: Construct an occlusal surface wear inhibition model; Based on the braces model, construct an occlusal surface wear inhibition model according to the degree of occlusal surface wear. Specifically, construct multiple occlusal parts on the braces, with different occlusal parts having different wear resistance.
[0016] Step 5: Construct a maxillofacial skin defect repair model; Based on the braces model, construct a maxillofacial skin defect repair model according to the degree of maxillofacial skin damage. Specifically, construct an elastic skeleton and storage compartment on the braces model corresponding to the maxillofacial injury site, and fill the storage compartment with anti-inflammatory drugs.
[0017] Furthermore, in step three, the method of using the caries inhibition model is as follows: guide the patient to bite down on the upper and lower teeth to break the broken ball. The casein phosphopeptide calcium phosphate complex inside the broken ball flows out through the pore and adheres to the caries tooth to inhibit the adhesion and growth of cariogenic bacteria.
[0018] Furthermore, in step four, the occlusal portion includes a low-density occlusal portion, a medium-density occlusal portion, and a high-density occlusal portion.
[0019] Furthermore, in step four, the method of using the occlusal surface wear inhibition model is as follows: when the patient grinds their teeth at night, different occlusal parts are subjected to the grinding of the patient's teeth. According to the patient's grinding force, the low-density occlusal part, medium-density occlusal part, and high-density occlusal part are subjected to biting treatment; according to the biting condition of the low-density occlusal part, medium-density occlusal part, and high-density occlusal part, the appropriate dental model material for constructing the patient is selected.
[0020] Furthermore, in step five, the method of using the maxillofacial skin defect repair model is as follows: when the patient's maxillofacial area is injured, the patient's maxillofacial skin is guided to tighten and exert force, so that the elastic skeleton and storage part are deformed under pressure. The anti-inflammatory drug in the storage part is squeezed out from the small hole and attached to the maxillofacial skin injury site to perform anti-inflammatory treatment on the injury site.
[0021] Furthermore, the dental braces model, caries suppression model, occlusal surface wear suppression model, and maxillofacial skin defect repair model were cross-combined to construct the model.
[0022] Beneficial effects:
[0023] (1) Based on the patient's 3D tooth model, a dental brace model adapted to the patient is constructed; based on the dental brace model, a caries inhibition model is constructed, using casein phosphopeptide calcium phosphate complex attached to the caries to inhibit the adhesion and growth of cariogenic bacteria; based on the dental brace model, an occlusal surface wear inhibition model is constructed, and materials suitable for constructing the dental brace model are selected according to the patient's bite damage to low-density, medium-density, and high-density occlusal areas; this facilitates the patient wearing the dental brace model at night, reducing the patient's tooth occlusal surface defects and affecting chewing efficiency; based on the dental brace model, a maxillofacial skin defect repair model is constructed, guiding the patient's maxillofacial skin to tighten and exert force, so that the anti-inflammatory drug in the storage part is squeezed out from the small hole and attached to the maxillofacial skin injury site for anti-inflammatory treatment; by constructing the caries inhibition model, the occlusal surface wear inhibition model, and the maxillofacial skin defect repair model, a multifunctional repair function can be achieved for oral soft and hard tissue defects.
[0024] (5) Based on the patient’s actual situation, the dental braces model, caries suppression model, occlusal surface wear suppression model and maxillofacial skin defect repair model can be cross-combined to construct the model. If the patient has caries and occlusal surface wear, the caries suppression model and occlusal surface wear suppression model can be combined to construct the model. Two or three models can be combined to adapt to the patient’s actual situation. Attached Figure Description

[0029] The following detailed description illustrates the specific implementation method:
[0030] The reference numerals in the accompanying drawings include: 1. Gingival sleeve; 2. Tooth sleeve; 3. Through hole; 4. Breaking ball; 5. Elastic skeleton; 6. Occlusal part.
[0031] The basic implementation examples are as follows: Figure 1-4 As shown:
[0032] A multifunctional device for repairing defects in oral soft and hard tissues includes a hollow gingival sleeve 1, on which several hollow dental sleeves 2 are integrally formed.
[0033] like Figure 2 As shown, several fragmented balls 4 are placed inside the dental crown 2, and the fragmented balls 4 are filled with casein phosphopeptide calcium phosphate complex; as shown Figure 1 As shown, the dental sleeve 2 has a through hole 3 for the outflow of casein phosphopeptide calcium phosphate complex.
[0034] like Figure 4 As shown, the dental crown 2 has several occlusal parts 6 integrally formed on it, and the wear resistance of different occlusal parts 6 is different; the wear resistance of the occlusal part 6 depends on the density of its building material.
[0035] The braces have a one-piece molded elastic skeleton on the side wall 2, such as... Figure 3 As shown, the elastic skeleton 5 is composed of several hollow parallelogram supports that are interconnected; the elastic skeleton 5 has several small holes; the elastic skeleton 5 has an integrally formed storage part in the middle, which is connected to the elastic skeleton 5 and is filled with anti-inflammatory drugs.
[0036] The construction method of a multifunctional device for repairing soft and hard tissue defects in the oral cavity includes the following steps:
[0037] Step 1: Constructing a dental brace model; A 3D model of the patient's teeth is created using an oral scanner, and a dental brace model adapted to the patient is constructed. The dental brace model includes gum line 1 and tooth line 2, as shown below. Figure 1 As shown.
[0038] Step Two: Assess the condition of tooth and facial skin defects; By taking pictures of the patient's oral cavity, the doctor can assess the condition of the patient's tooth and facial skin defects; The criteria for assessing tooth defects are: the location of the cavities and the degree of wear on the occlusal surface; The criteria for assessing facial skin defects are: the degree of facial skin damage.
[0039] Step 3: Constructing a caries suppression model: Based on the brace model, a caries suppression model is constructed according to the location of the caries. Specifically, a fragmented sphere 4 is constructed inside the brace 2 for teeth with caries, such as... Figure 2 As shown, the broken ball 4 is filled with casein phosphopeptide calcium phosphorus complex, and an opening 3 is made on the side wall of the tooth sleeve 2 near the carious tooth defect.
[0040] Step 4: Construct an occlusal surface wear inhibition model; Based on the braces model, construct an occlusal surface wear inhibition model according to the degree of occlusal surface wear, specifically as follows: Figure 4 As shown, multiple occlusal portions 6 are constructed on the dental crown 2, and the wear resistance of different occlusal portions 6 is different.
[0041] Step 5: Construct a maxillofacial skin defect repair model; Based on the braces model, construct a maxillofacial skin defect repair model according to the degree of maxillofacial skin damage. Specifically, construct an elastic skeleton 5 and a storage part on the braces model corresponding to the maxillofacial injury site, and fill the storage part with anti-inflammatory drugs.
[0042] In step three, the caries inhibition model is used as follows: the patient is guided to bite down on their upper and lower teeth to break the broken ball 4. The casein phosphopeptide calcium phosphate complex inside the broken ball 4 flows out through the through hole 3 and adheres to the caries tooth to inhibit the adhesion and growth of cariogenic bacteria.
[0043] In step four, the occlusal portion 6 includes a low-density occlusal portion, a medium-density occlusal portion, and a high-density occlusal portion.
[0044] In step four, the method of using the occlusal surface wear inhibition model is as follows: when the patient grinds their teeth at night, the low-density occlusal, medium-density occlusal and high-density occlusal parts are treated by biting according to the patient's grinding force; based on the biting condition of the low-density occlusal, medium-density occlusal and high-density occlusal parts, the appropriate dental model material for constructing the patient is selected.
[0045] In step five, the method of using the maxillofacial skin defect repair model is as follows: when the patient's maxillofacial area is injured, guide the patient's maxillofacial skin to tighten and exert force, so that the elastic skeleton 5 and the storage part are deformed under pressure. The anti-inflammatory drug in the storage part is squeezed out from the small hole and attached to the maxillofacial skin injury site to perform anti-inflammatory treatment on the injury site.
[0046] The model was constructed by cross-combining the braces model, the caries suppression model, the occlusal surface wear suppression model, and the maxillofacial skin defect repair model.
[0047] The specific implementation process is as follows:
[0048] 1. Construct a caries suppression model
[0049] The first step is to create a 3D model of the patient's teeth using an oral scanner, and then build a braces model that is adapted to the patient.
[0050] The second step involves taking pictures of the inside of the patient's mouth so that the doctor can determine the location of the cavities.
[0051] The third step is to construct a caries inhibition model based on the dental brace model and the location of the caries. Specifically, a fragmented sphere 4 is constructed inside the dental brace 2 where there is caries. The fragmented sphere 4 is filled with a casein phosphopeptide calcium phosphate complex. An opening 3 is made on the side wall of the dental brace 2 near the caries defect.
[0052] The fourth step involves guiding the patient to bite down on their upper and lower teeth to break the broken ball 4. The casein phosphopeptide calcium phosphate complex inside the broken ball 4 flows out through the through hole 3 and adheres to the carious tooth to inhibit the adhesion and growth of cariogenic bacteria.
[0053] 2. Construct a model for inhibiting wear on the occlusal surface.
[0054] The first step is to create a 3D model of the patient's teeth using an oral scanner, and then build a braces model that is adapted to the patient.
[0055] The second step involves taking pictures of the patient's oral cavity to allow the doctor to assess the degree of wear on the occlusal surfaces.
[0056] The third step is to construct an occlusal surface wear inhibition model based on the dental brace model and the degree of wear on the occlusal surface. Specifically, multiple occlusal parts 6 are constructed on the dental brace 2, and the wear resistance of different occlusal parts 6 is different.
[0057] The fourth step involves treating the low-density, medium-density, and high-density occlusal surfaces based on the patient's grinding force during nighttime bruxism. When the grinding force is relatively small, only the low-density occlusal surface is damaged; when the grinding force is moderate, both the low-density and medium-density occlusal surfaces are damaged; and when the grinding force is large, all three occlusal surfaces are damaged. Based on the extent of damage to the low-density, medium-density, and high-density occlusal surfaces, suitable materials are selected for constructing the dental model for the patient. This facilitates nighttime wearing of the dental model, minimizing occlusal surface defects and reducing chewing efficiency.
[0058] 3. Constructing a model for repairing skin defects in the maxillofacial region
[0059] The first step is to create a 3D model of the patient's teeth using an oral scanner, and then build a braces model that is adapted to the patient.
[0060] The second step involves taking pictures of the inside of the patient's mouth so that the doctor can assess the extent of skin damage to the maxillofacial region.
[0061] The third step involves constructing a maxillofacial skin defect repair model based on the braces model and the degree of maxillofacial skin damage. Specifically, an elastic skeleton 5 and a storage compartment are constructed on the braces model corresponding to the maxillofacial injury site, and anti-inflammatory drugs are filled into the storage compartment.
[0062] The fourth step involves guiding the patient's facial skin to tighten and exert force when the patient's facial skin is injured. Since the elastic skeleton 5 and the storage part are located between the dental model and the patient's facial skin, when the patient's facial skin tightens and exerts force, the elastic skeleton 5 and the storage part are deformed under pressure. The anti-inflammatory drug in the storage part is squeezed out from the small hole and adheres to the injured area of the facial skin to treat the injury.
[0063] 4. Based on the patient's actual condition, the braces model, caries suppression model, occlusal surface wear suppression model, and maxillofacial skin defect repair model can be cross-combined to construct the model. If the patient has caries and occlusal surface wear, the caries suppression model and the occlusal surface wear suppression model can be combined to construct the model. Two or three models can be combined to adapt to the patient's actual condition.
