When the best orthodontics?

Now, irregular teeth, people will choose to use orthodontics to make their own teeth become beautiful, then the appropriate time for orthodontic what is it? The following experts under orthodontic appropriate time to introduce, I hope for your help.

Dental Hospital experts believe: orthodontics, although there is no specific age limit, but generally speaking, the 12-year-old orthodontist's the right time, mainly because:

It turned out that from birth to the end of adolescence, people's teeth are always in the growth and development and replacement process, especially at the primary stage of deciduous teeth fall eruption of permanent teeth, the second stage and final with the teeth. After the eruption of the permanent teeth, the arrangement of the teeth of the mouth to dental equipment determine the basic down, this time will show whether orthodontics.

So why not choose the best orthodontic age adult, adult alveolar been completely grown, not easy to change the arrangement of the braces, the teeth of 12-year-old juvenile also relatively easy to correct.

Orthodontic braces and porcelain teeth of these two. Braces suitable for teeth in order to change the most suitable orthodontic age of The role of deciduous permanent tooth germ secondary stage; porcelain teeth used in a wider range of adults can also use porcelain teeth play a very good oral cosmetic effect, not only allow dental tidier, you can also whiten teeth, so that has a pale translucent beauty of healthy teeth.

Tooth to be careful that can affect memory

Many people have had the experience of tooth extraction, but now you have to pay attention to, except as a last resort, otherwise do not easily pulled out your teeth! According to U.S. media reported on December 17, Swedish scientists published study shows, tooth extraction part of the memory of when people will disappear.

I Umea University, Sweden researchers from 1988 to 1962 volunteers aged between 35 years old -90 years old 15 years of follow-up survey. In the memory of the teeth sound and dental equipment extraction were compared, the researchers found that, in the case of exclusion of factors such as education, age, medical history, teeth and improve memory significantly better than pulling teeth.

I Umea University Dental Associate Professor Jan Bergdahl said: "Research shows that tooth can cut the nerve of the tooth leading to the brain, thus affecting the memory. This is a breakthrough for the elderly dental status and amnesia, he also pointed out that such a large-scale studies have not previously been human. Previously, the Japanese scientists Crossbite orthodontic treatment of anterior teeth and root on the relationship between rat teeth and memory research found that mice after tooth was pulled out the memory were not as good as those teeth healthy mice.

Why so expensive dental implant?

When it comes to dental implant the majority of patients will find how expensive dental implant? Expensive dental implant, but its effects can not be compared in the way of any oral health care repair, because of the dental implant is expensive, so promoting it is very difficult.

The dental implant comfort, aesthetics, already accepted by patients with tooth loss and recognition, expensive dental implant is also well known things. The dental implant prices are more expensive reasons:

1. Expensive dental implant materials: the high cost of dental implant materials of the craft techniques, dental implant prices can not reduce.

2. The dental implant devices: In addition to the material outside of the dental implant process also need to X-ray examination, clinical treatment, mechanic equipment, and dental equipment so the cost is quite high, is another reason for the high price of dental implants. Recommended reading: dental implant hazards that you know what

3. Affect the price of dental implant dental implant expert resource scarcity: whether to study or to the final clinical use of the dental implant technology have invested considerable human resources, Dental Implant and Gingival color porcelain former the use of dental porcelain restoration our professional staff is very scarce, so the high prices of dental implants also appear to be normal.

Anterior teeth scattered gap porcelain repair

Treatment: Patient’s front teeth scattered in the gap in the number of Teratology Hospital Advisory, the answer is given maxillary doing eight porcelain teeth, and dental equipment shall kill the nerve, in order to solve the problem of scattered gap.

Patients to hospital consultation, after detailed examination, only four porcelain teeth, no need to kill the nerve by the inclination to solve the teeth to reduce the effect of powder in the gap. Using this method, not only retained in patients with healthy teeth, but also saves the cost of treatment, and Early childhood prone to dental caries patients restored the effect is also very satisfied.

Dentition defect fixed partial denture

Fixed partial denture repair dentition in one or several missing teeth, anatomy and physiological function of a prosthesis, also known as a fixed bridge. Usually based on a fixed partial denture structure is divided into a double-ended fixed partial dentures, semi-fixed partial dentures, fixed cantilever prostheses. Clinically used materials are divided into casting fixed dentures, the swaged fixed partial dentures and metal ceramic fixed partial dentures.

One. Indications

1. Is generally believed that the 20-55 year-old who can be the most appropriate age is 20-45 years old, less than 17 years of age are generally not considered.

Two. The number of missing teeth should not be too much, generally assume a missing teeth than the two abutments.

3. Lack of alveolar ridge fullness or fullness.

4. Abutment teeth, crowns, large, straight root, thick, long, tooth position.

Two. Production steps

1. Cast fixed partial dentures and metal ceramic fixed partial dentures.

(1). the abutments Select: periodontal health, supporting role; form tall crown root solid retention role; the location of the abutments is, in place.

(2). the decision of the number of abutments: In general, choose a double-ended on both sides of the missing teeth do abutments, special circumstances can be dental equipment used single-ended fixed.

(3). Tooth preparation: ask the same casting crowns and metal-ceramic crowns.

(4). take an impression of the irrigation model: Preparation of abutment teeth after gingival retraction cord compression, dentition impression silicone impression material to take, anhydrite irrigation model.

(5). Wax pattern production: in the model of the prepared teeth coated with a separating agent, wax-type placement sprue.

(6). Embedding, casting: Casting phosphate-bonded material embedded, high-frequency centrifugal casting machine.

(7). Bridge test together: casting the completed bridge sandblasting, cleaned, polished after the trial together.

(8). Non-metallic part of the production: The production of plastic bridge is the bridge self-curing or heat curing resin system. Burn attached to Fixed partial denture maxillary full dentition porcelain production, the use of painted porcelain, burn attached to the method of making a fixed bridge.

(9). Test together, cements.

2. The swaged fixed denture.

(1). Tooth preparation: with swaged to metal crowns.

(2). take an impression of irrigation model: to use seaweed sodium impression paste to take an impression of ordinary gypsum filling mode.

(3). the retainer’s production: swaged crown.

(4). Retention test together: the swaged crown clean abutments after the trial co-

(5). take a collection mode: all solid bit body after the trial co satisfied modulo.

(6). Bridge and connecting body production: including the hammer made the metal forworn panel, welding the bridge, the formation of the plastic part of the bridge.

(7). Test together, cements.

The periodontal fixed partial denture

Periodontal disease associated with dentition defect of the fixed partial denture long-term results were satisfactory, but need to pay attention to adapt to the levy choices and regular observation.

Periodontal disease is an infection of the disease, that is, bacteria play a decisive role in the occurrence of periodontal disease, the development of

Journal of Clinical Stomatology June 6 published a study, researchers from 1997 to 2004, 325 cases of periodontal disease with dentition defect cases, the use of metal ceramic crown and bridge or metal casting crown and bridge repair, repair after 1 year 2 years and 5 years of follow-up, fixed partial dentures, chewing performance and dental health status to dental equipment assess its long-term effects. Periodontal disease associated with dentition defect long-term efficacy of the fixed partial denture cases were followed up to investigate the clinical factors related to long-term effects.

Therefore, periodontal disease can be seen with the fixed partial denture repair defective dentition long-term effects satisfaction, but require attention to Dental orthodontic tooth more than 60% meet the levy choices and regular observation.

Deep caries of deciduous teeth root canal bacteriological analysis

The purpose of this study is to analyze with deep caries of primary teeth root canal bacteria. Methods 12 deep caries of deciduous teeth, of which three have hot and cold to stimulate the pain, the remaining nine had no clinical symptoms in the micro-aerobic and anaerobic under the risk of root canal bacteria isolation and identification. results show symptoms of teeth colony forming units higher than the asymptomatic teeth, but no significant differences between the two in both groups, the similar composition of the root canal bacteria and of deep caries bacteria Streptococcus mutans and Lactobacillus accounted for the proportion of culturable bacteria than other bacteria, the difference was significant, and Streptococcus mutans and Lactobacillus detection rate is dental equipment higher than other bacteria, the difference was also significant obligate anaerobes, such as digestive the Streptococcus, Wearing Shi bacteria, Fusobacterium and Prevotella has also been detected, but its detection rate and accounted for the percentage of cultures were very low. Conclusion microaerophilic cariogenic the bacteria of milk Keywords: deciduous teeth with deep caries root canal bacteria

Is generally believed that deciduous dentine is thin, the poor degree of mineralization, deep caries infection can easily spread to the pulp, the clinical treatment of deep caries often to save the teeth for the purpose of the preservation of life pulp not pay enough attention to. Save the vital pulp of deciduous and permanent teeth induction of great significance, the pulp is closely related to Correction extraction of six problems some extent, and it’s within the number and types of microorganisms. Looking reported in the literature, few studies on deciduous teeth with deep caries microbiology, this study attempts to learn deciduous teeth with deep caries pulp microbial analysis for clinical treatment, bacteriology reference.
