What is the number of early childhood tooth decay?

Caries a strange polarization: The crowd parts of the people who have no dental caries, some people have a lot of dental caries. Often up to more than 70 percent of tooth decay is concentrated in 30% of oral.

The study found that the main factors of children suffering from dental caries daily brushing less than twice the plaque eat sweets more than twice, enamel developmental defects.

Brushing can effectively remove plaque, brushing your teeth at least twice, and effective measures to maintain oral health. At the same time emphasize the number of children brushing, but also focus on the effect of supervision of children brush their teeth.

Prevention of dental caries and the basis of knowledge

1. Enhance the anti-caries of the teeth

Increase by fluorination of fluorine in the teeth, especially to change the structure of the enamel surface, in order to enhance the anti-caries of the teeth. Is now considered better method of fluoride: tap water fluoride, school water fluoridation, dental topcoat fluoride, fluoride toothpaste, fluoride solution mouthwash.

Any fluoride anticaries methods are only used for the fluorine-free water or low-fluoride area, you can not use in high fluoride areas. In addition, children with dental fluorosis should not be using the fluoride method. This method does not adapt to young children.

2. Reduce or control the sugar content in the diet

Parents should educate our children develop the habit of eating snacks and sweets, especially before going to bed, pay attention to the children three meals a day with a reasonable habit of children to eat more vegetables, fruits, and dental instruments rich in calcium, phosphorus, vitamin food. In addition, we should pay attention to the baby's breastfeeding.

3. Reduce or eliminate pathogenic irritants

The most practical and effective way to brush your teeth and mouth as possible after each meal should gargle, sooner or later, brush your teeth once. Scrub the teeth of children by parents with a soft towel or flannel. After each suck cleaned once.

This would increase the gum tissue blood circulation and make the gums to become firm, but also helps the eruption of the teeth, but also helping to Five common misunderstanding of the orthodontic train a refreshed feeling and habit to clean the mouth. Children over the age of 3, you can try to brush your teeth.

Why do teeth missing?

There are many reasons, including genetic and environmental factors. Environmental factors, including congenital and acquired factors. Birth trauma caused by innate factors affecting the growth and development of the fetus in the mother's womb by the mother or the fetus nutritional and metabolic disorders, mothers suffering from rubella or virus infection during pregnancy by trauma or dental instruments childbirth.

Acquired factors is pointed out that students are in the process of growth and development. (1). Diseases: some acute infectious diseases, some chronic wasting disease that may affect the development of teeth and jaw. Endocrine dysfunction, or malnutrition, especially vitamin deficiency may affect the development of the teeth and jaw. (2). Breathing and swallowing dysfunction may affect the development of the teeth and jaw. (3). Bad habits such as biting, bite the upper lip or Oral microbiology and dental implants the Yaoxia Chun habits, Shenshe the tongue habits. (4). of deciduous or mixed dentition. Including deciduous premature loss of deciduous teeth can not afford to delay, the permanent teeth of premature loss of permanent teeth eruption order of disorder can cause teeth missing.

Porcelain dental care measures?

Many patients feel that porcelain teeth only good materials, its life will last long. However, it is just one impact. Because, even if the material of porcelain teeth, no matter how good, also requires the meticulous care of the patient's own, in order to better play the role of porcelain teeth. What the finished porcelain dental restoration, you need to pay attention to what care?

The experts pointed out that: care for porcelain teeth, no doubt from the two aspects of protection.

One. Diet: do a good job of porcelain teeth, restored teeth chewing function, therefore, and is often used in life. In terms of diet, mainly on these two aspects of attention:

1. Try not to eat excellent food, after the repair of porcelain teeth, take some time to adapt, not adapted, excellent bite of food, is likely to stimulate the porcelain teeth oppression of the gums and other organizations, such as gingivitis inflammation. Fully adapt the oral environment in porcelain teeth, try not to chew hard objects to avoid too much pressure to porcelain teeth, leading to the phenomenon of deformation or collapse porcelain teeth are more likely to occur porcelain teeth off the case.

2. Spicy food try not to eat, because the metal of the porcelain teeth crown some unstable chemical properties, may be vulnerable to chemical reaction, such as: lead acid food spicy food and life. Certain ions in the metal material will be in the Free State, easy to stimulate the gums and other parts, resulting in human allergic phenomenon.

Two. Clean areas: at the finish of porcelain teeth, the patient should always concern about the cleanliness of porcelain teeth, good oral hygiene habits. In this case, to maximize the improvement of the service life of porcelain teeth. For example: If the patient does not develop a good habit of cleaning the oral cavity, food residues accumulate around the porcelain teeth organizations, the growth of bacteria, the occurrence of tooth decay and other oral diseases, and dental instruments ultimately may remove the porcelain teeth to re-create the situation. Therefore, patients should always pay attention to oral hygiene, to develop a habit of gargling after a meal brush your teeth.

Therefore, porcelain teeth care, patients and friends should cause great concern is the Do care, at the same time, because porcelain teeth can not only extend the life of porcelain teeth, and more effective protection of the oral health. Because, during the porcelain dental care, also the maximum extent possible to reduce the incidence of oral diseases.

These are the People's Armed Police Corps Hospital of Pregnant women's oral health affects fetal development Province oral treatment centers experts for your introduction; I believe will bring you help. If you are in need of treatment, must be a regular hospital treatment, do not miss the best time for treatment.

Implant fixed complete denture how to repair?

As long as a sufficient number of good healing of the implant can be supported fixed complete denture. In many cropping systems, bran mark system is relatively complete set of fixed full mouth implant denture repair of clinical procedures.

1. The number of implants required and site: bran mark, system implants need four to six implants in order to provide adequate support to complete denture, conventional single jaw implants six implants. The site of the planting should be near the lateral wall of the maxillary sinus nearly or mandibular mental foramen, which is equivalent to the area between the first premolars. In order to force a better distribution, in the end determine the maxillary sinus and dental instruments the location of the inferior alveolar nerve after planting to the molar area. Mandibular implant after three months and maxillary implant six months to fix.

2. Take an impression.

3. Transfer of jaw relations and on occlusal rack.

4. Row of teeth: the planting of denture tooth arrangement still follow the usual principles.

5. Production of the bracket: with bolts pre superstructure and abutment connection, connect the pre-casting wax or self-curing resin into the upper structure, the formation of the prototype stent.

6. Due to test stand: metal stent trial together, into the mouth tried on patients, such as can not be successfully in place will be Alice moving, and Fusion-style planting the production of full-mouth fixed denture cut off welding, or otherwise dealt with, the main reasons for the casting shrinkage.

7. Transfer row of teeth: the formation of wax care with metal stents, and adjust its beautiful shape.

8. Appropriate test row of teeth after the completion of the restoration.

9. Tried on: the production after the completion of the fixation of denture try them, should first check the insertion of artificial teeth bit with or without changes, wearing a fashionable check denture bracket with each base station passive suitability, and then bolted.

Fixed partial denture missing teeth

The bridge is an important part of the fixed partial denture missing tooth morphology and function. The designs of the bridge directly affect the repair effects and oral health. The bridge should have the following conditions:

(1). Able to restore form and function of the missing teeth.

(2). the role of self-cleaning, to meet the oral health requirements.

(3). Have sufficient mechanical strength, chemical stability and good Histocompatibility.

(4). Beautiful and comfortable.

In the bridge design should consider the following questions:

(1). the occlusal surface of the bridge: First occlusal morphology better, sharp clear pit and fissure ridge, is conducive to chew. Second, the size of the occlusal surface than dental instruments normal teeth small, in order to reduce the occlusal force.

(2). gingival surface of the bridge: one to keep clean; second, good-looking; the Mihashi abutment height smooth to prevent inflammation.

(3). The axial plane of the bridge: In addition to the resume form, to meet the aesthetic requirements, but also pay attention to food row overflow, to restore the correct shape and protrusion

(4). Bridge's strength: the strength of the bridge refers to the Implant plaque control and removal bending strength of the bridge. To occur when the bridge to withstand the occlusal scratch, abutments will produce the response of the flexor moment when the flexor moment stress is greater than the retention force of the retainer, make the retention of cortical from the abutment.

Planting bridge repair design

Planting bridge repair is the repair of fixed partial denture implant two or dentition defect caused by more than two missing teeth, implants, generally planted more than two implants.

China used two planting two missing tooth implant or repair the same number of more than one missing tooth implant-supported joint bracket, and some referred to Crown. More than one missing tooth, the number of implants is less than the number of missing teeth, so that manufacturing fixed implant planting bridge. Actual production and non-discriminatory, just as the implant's ability to support. Bran mark system according to different sets of classification for part of the implant restoration: standard base station, beautiful base station, small base station, the angle from base stations can also be dental instruments made from base stations. Design implant to support, a single implant can support 400 Newton; two implant repair support the 1300 Newton. Two implants can support three to four teeth, 5 to 6 implants to support a fixed denture.

The implant system design:

(1). Planting of a single system, such as a single system implantation of cylindrical implants, screw implants, leaf-shaped planting.

(2). Combination of planting, such as front teeth with a cone-shaped implant, posterior leaf-shaped implant.

(3). the surgery can use the planting of the first surgery, second surgery planted.

Implant design:

(1). Divided into a retention Cementation type and bolt retainer type.

(2). Use is divided into a temporary repair and permanent restoration.

(3). the structure can sometimes be divided into the joint crown and fixed bridges.

(4). Material into a plastic prosthesis, porcelain restorations, glass-ceramic restorations.

(5). Abutment type is divided into a beautiful type and standard.

The physiological basis of fixed partial dentures

Fixed partial denture suffered together to completely rely on the abutments to bear. Fixed partial denture has been able to withstand the force of the missing teeth, because it has compensatory missing teeth. Dentition defect cosmetic restoration treatment, according to the retention mode is divided into removable partial denture, fixed denture implant denture. Removable partial dentures supported by natural teeth and mucous membranes, through the retainer and dental instruments the base plate denture assembly in the dentition, patients can choose their own wear. Fixed partial dentures missing teeth across the gap or the end of the natural teeth for support, connected through the retention of artificial teeth, and with the cements denture luting natural teeth, the patient can not choose their own to wear. Implant denture implant implanted within the jaw, and then exposed on the mouth planting pile fitted dentures, like natural tooth morphology and function.

Carrying out a number of diseases of the mouth before the first denture treatment, such as dental caries, endodontics, root disease, periodontal disease and root. Disease to be more than a thorough treatment after tooth preparation or Implant plaque control and eliminate way implantation of artificial root, modulo, and finally complete denture making.
