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.

Dental implant design

Thorough system of general and local check, confirm that patients with indications for dental implants, and decide to implement the planting surgery to repair. Then the doctor to develop the implant restoration program.

1. The choice of cropping systems: the choice of cropping systems to be combined with the condition of the patient and doctor choice. Preferred implant system is reliable, whether the bulk of cases of long-term observation of clinical practice, whether there is really satisfactory results.

2. Patients with mandibular bone quantity and quality: the case of X-rays, an accurate picture of the anatomical structure of the growing areas.

3. The economic conditions of the patients: of the main factors limiting the implant restoration development is the price, the foreign implant its price is high, and it is difficult to accept as a universal.

4. Choice of planting site: from the perspective of repair, the most in the Distal implant in the alveolar and distal end to provide support; missing teeth gap is too long to implant in the middle of the missing gap, bridge base; no teeth timely, bracket fixed complete denture and dental equipment implant-supported overdenture.

5. Planting to determine the number: in the end the number of one implant, there are two factors: first, the need to support the prosthesis and the second is the possibility of anatomical conditions.

6. The choice of implant superstructure: According to the techniques mastered by the patient's specific circumstances, physicians and patients can be selected as appropriate multi-type retention device to complement each other.

The retrograde design rules can accurately complete the design, to achieve the best effect. According to the requirements of aesthetics and occlusion in the row of teeth on the model to Fixed partial denture retention of several reasons determine the type of repair, superstructure, implant planting site, planting the number of planting direction and the length of the implant. Which determine the final outcome of repair, reverse derivation Select prostheses and implants? The implementation of carrier retrograde design rule is the surgical template, and finally achieves the original design requirements can be controlled by the template.

How long can porcelain teeth in the end?

For the life of porcelain teeth, do not have an accurate figure, Changchun Dental Hospital experts say: the average life expectancy of the general porcelain teeth are more than a decade, the porcelain teeth longevity depends on the material of porcelain teeth and grilled porcelain teeth postoperative care.

Some people say that the porcelain teeth the average life expectancy is 8 years to 10 years, some 15 years. From a practical point of view, the same material of porcelain teeth, it was only three to five years dentures tend to die young, there is some 15 years, but looks good. The experts pointed out that the porcelain teeth how long can relate to many factors, the porcelain teeth of each patient's life is different.

In addition to materials, production process, not the same as the basic conditions of each human tooth is to determine the porcelain teeth can how long an important factor. If each tooth fixed root and the root is very solid, no basis of dental this case, inlaid porcelain teeth with no problem for decades. Conversely, if the patients with root damage, more missing teeth, or dental equipment often guilty periodontal disease, even if the quality is very good gold porcelain teeth, may also spend the coming year would come to an end. Want to apply the so-called average life expectancy, there is no basis. In addition, the usually careful care of dentures, real teeth and periodontal, of course, will increase the life of porcelain teeth.

The experts pointed out that: a porcelain teeth does not mean that once and for all, be careful to protect very important. Raw material reasons, most porcelain teeth to a limited extent by force, once more than this the intensity can be easily damaged teeth, and even affect its life, therefore, early wear should eat soft foods, best not to use porcelain teeth to chew on hoe, eating crabs and other foods. Porcelain teeth and abutment joints easy to assemble the plaque to form calculus, attention should be clean, available floss between the teeth and regular visits to the hospital for examination, cleaning teeth.

The dental implant is the best way to fix missing teeth

Despite the high price of dental materials, planting, but do not have to like to wear the adjacent teeth like a traditional dental expense of the life expectancy is more than twice that of the latter, so this technology in clinical practice has been a lot of edentulous patients favor.

Dental implant similar to a nail-like metal implants, teeth in the absence of the original location of this root "nail" implants alveolar act as a root, and then as a basis bordered dentures so than traditional The denture is more secure. Meanwhile, the dental implant does not involve damage adjacent teeth, which is the biggest advantage. And biomechanical principles of dental implants and natural teeth, natural teeth within the oral chewing pressure is passed through the root to the alveolar bone, dental implant chewing pressure through the implant is passed to the alveolar bone, dental implant force strength and chewing substantial increase in efficiency than conventional dentures.

Although the dental implant has many advantages, but not apply to everyone. For patients with full mouth teeth fall out or can not find healthy teeth, because they can not build a porcelain bridge, the past can only be installed dentures.

Theoretically, from teenage maxillofacial development of young people to more than 80 years old a dental implant. However, dental implants, oral inflammation, patients with mucosal disease, bleeding disorders, hypertension, heart disease, diabetes, osteoporosis, psychiatric, endocrine and dental equipment other systemic diseases, treatment in these patients are stable after you can receive dental implants.

How cosmetic discolored teeth?

Tetracycline a discolored tooth once formed is difficult to eliminate the serious harm to young people in physical and mental health, and the modern methods of treatment can be broadly divided into:

The first method is a bleaching method; it is suitable for dyeing to a lesser extent. Type of bleach, but the main ingredients of peroxide in urine, while the active ingredient is the peroxide in urine hydrogen peroxide, the bleaching effect of hydrogen peroxide oxidation, the specific use to consult a doctor.

The second method is a photosensitive resin cover, heavier staining in severe teeth. The general practice in the patients mouth, the direct use of the etching agent deal with the tooth surface will apply an adhesive composite resin covering the teeth, formed visible light curing, this method is short operating time, the price is cheaper . Asian and African Dental recently introduced a Swiss porcelain resin, which is characterized by adding 80% of the ceramic material on the basis of the composite resin in the past, so wear high polishing effect, with a similar sense of refraction with real teeth. Materials, rich colors, 15 colors, divided enamel color, transparent color of the dentin color and the cut ends. The multi-purpose adhesive used with the hydrophilic adhesive can be bonded to enamel and dentin bonding solid and durable. The introductions of porcelain resin porcelain material and greatly improve the effect of light-cured resin to repair defects in teeth, cover discolored teeth.

The third method is porcelain veneers covering method is only the labial surface of the discolored teeth grinding in addition to about 1 mm, and dental equipment then takes the model to produce a thin porcelain surface; bonding to cover part of the tooth has been rubbed off the lip surface. Such rubbed off by the overlay method of tooth structure, is produced in vitro model, color and shape than porcelain resin coverage results directly in the mouth. They use the Swiss multi-functional resin adhesive, a high degree of enamel and dentin bonding.

The fourth method is the all-ceramic crowns covering method is especially suitable for moderate to severe discoloration and arranged to disorder of teeth, patients wish to Your teeth need to be corrected correct arrangement of teeth, cover discolored teeth. This approach rubbed off the tooth structure and more, the costs are relatively high.

Braces correction does not work

Developmental stages of the main reasons caused by bad habits, for example, often a child with a pacifier to sleep, childhood biting pencil, the habit of sucking fingers, tongue, or nasal cavity long-term ventilation, frequent mouth breathing, as well as caused by maxillary malformations of the bone or the mandible. Normal tooth growth and development from infancy, the maxillary first development of the lower jaw development of the normal development of the upper jaw slightly longer than the mandible. Because of genetics or bad habits lead to development of abnormal, some excessive mandibular the upper jaw, to prevent its normal development, the formation of 'package days,' while others are contrary to the formation of 'buck teeth'. "

It is noteworthy that there are many face problems, but also because of the teeth jaw deformities, such as open lips grin, a long face, short face, or facial asymmetry, and so on.

The latest technology enables fixed facial bone

According to reports, a tooth jaw deformity due to "buck teeth", "Package Days" to orthodontic alone can not be corrected, the need for surgical reset, but the recognition of such patients is very low, only a small part of surgical correction, most of the other or dental equipment no awareness of straightening teeth laissez-faire, or be mistaken for the general dentition, adopted a simple method of orthodontic According to reports, a single from the outside and can not determine whether there is tooth jaw deformities, mainly rely on clinical inspection and shooting anteroposterior and lateral X-ray and modulo to diagnose.

It is understood that through minimally invasive surgery to correct my teeth and surgery do not need to wear braces, do not need to move to the facial supporting bone. "The principle is minimally invasive incisions to open the alveolar directly adjust the teeth and jaw, the key is to regroup in the relations and the ratio of pre-designed facial structure facial bone position." According to Five eat so that the teeth to change whitening reports, the whole operation time of about 1 hours, intraoperative outlook can be improved, after three days you can resume normal diet, the incision in the oral cavity after surgery do not see any traces.

Whitening strips VS Sandblast cleaning teeth

Whitening strips: urea class hazardous to your health

U.S. researchers found that: whitening strips sold in the market, some add the ingredients of urea, ureas stimulate the gastrointestinal tract, and there are potential hazards on the human body.

In addition, there are some whitening strips use the main ingredient hydrogen peroxide, although relatively safe, but the sensitivity to the people should pay attention to the proportion of, when the hydrogen peroxide from 15% to 35%, easily causing tooth sensitivity. Oral soft tissue and gums can also be stimulated.

Blast cleaning teeth: save time, money and health

Blast cleaning teeth, also known as scaling, using ultrasonic high frequency vibration to clean the plaque. Special salt sand and high pressure water further cleaning teeth. Ultrasonic scaling can only chunk of tartar in the mouth vibration under blasting tea can be attached to the teeth, dirt, smoke, dirt and food debris in factoring is clean, spray the teeth of the sand very smooth, and difficult to re-deposition of calculus, scaling and blasting should be combined.

And doctors at the same time scaling for you, you can timely detection of a variety of risks in your mouth and timely remedy. Some of my friends think that scaling can cause tooth pain or loose teeth, it is because of the long-term is not clean teeth lead to gum recession caused by. Dental care of the best friends in six months to wash your teeth and dental equipment do a physical exam to the teeth.

Therefore, the blast cleaning teeth as the best way to protect teeth and healthy, save time and money.

Dental expert tips:

1. If the processes of using feel dental pain, stop using them immediately.

2. The whitening strips can not increase the amount of use a day or Dental experts recommend dental Privacy Policy Manual once every three months, otherwise it will destroy the tooth structure.

3. If ordinary people want to accept the teeth whitening is best to go to the dentist, gums, unhealthy people do not blindly.

Best time of denture after tooth extraction

Denture, called in outpatient Prosthodontics, or repair activities, fixed restoration. If a person has missing teeth to eat is certainly inconvenient, not only affect the masticatory function but also affects the appearance, but also have a certain impact on health. Many people believe that teeth pulled out, as long as the wound healing that is needed. This understanding is not correct.

Dentition middle teeth pulled out, leaving the gap, and easy to impaction of food, the long period of time occurs caries and periodontal disease, while the elongation corresponding to the teeth, missing teeth and gaps, resulting in the exposure of root Ministry affect its soundness. In addition, give some teeth to bring some difficulties. Extraction in adolescence is dental equipment not yet timely teeth, may cause more teeth shift, the occurrence of teeth arranged in disorder, causing lifelong pain. Thus, missing teeth must be promptly repaired.

Under normal circumstances, about 2 to 3 months after tooth extraction, denture fit, this is because the tooth extraction wound completely healed at the need for a process.

If the wound does not have long good teeth, due to the absorption of alveolar bone, tooth extraction wound also changes, there will be gap between the denture and the gum tissue, resulting in food impaction, bad breath, dentures loose and not solid, you may want to Anti-jaw deformity re-install. Denture and do not wait too long, more than six months are not false teeth, surrounding good teeth are more or less a little tilt to the missing teeth gap will affect the future dental restorations.

How do wear braces gum pain?

Wearing braces gum pain are generally temporary, as long as good oral hygiene, gingival inflammation will disappear, and when the end of orthodontic treatment, periodontal tissue can return to normal, no permanent damage to periodontal tissues.

Wearing braces gum pain: plaque retention is the direct cause leading to periodontal tissue inflammation, wearing a ring on the mechanical stimulation of the gums, place wearing a ring of bacterial species in subgingival plaque change, too much binder dental equipment on mechanical stimulation of the gums, the trauma of tooth movement in the jaw, inappropriate tooth movement during orthodontic treatment, when the appliance close the extraction gap, the gap parts of the gums with the relationship between the gap and wrinkled and hyperplasia.

Wearing braces gum pain solution: the health problems of varying degrees of periodontal tissue to After tooth extraction must be the teeth orthodontic experts: the use of fixed appliance orthodontics, usually just some light, some a little more seriously, generally as long as good oral hygiene, inflammation will disappear.

Straightening teeth need extraction?

Generally according to the degree of crowding, pulling non-extraction also depends on the orthodontist's experience and technology. In terms of crowding, to advance understanding of straightening teeth need extraction can choose the most suitable for their own treatment programs.

Orthodontic needs extraction depends on the following factors:

The first teeth congestion level. Generally severe crowding will only consider the extraction of the solution to crowding. Mild teeth crowded and generally pull from time to dental equipment pull orthodontists experienced and technology.

Followed the doctor's experience and technology. The orthodontic experienced doctors, will eradicate the patient's teeth in order to decide whether to The denture How to protect the health of the gums adopt the tooth expand the dental arch, and the pull of which teeth, bilateral symmetry extraction or unilateral extraction.

Because the tooth's purpose is to solve the crowding, straightening teeth need extraction only crowding, other malocclusion, orthodontics does not need a tooth extraction.
