no brackets invisible braces

Missing teeth bite can be used without brackets invisible corrective surgery to repair without brackets invisible surgery allows patients in the beautiful and comfortable succeed in straightening teeth. No brackets invisible braces are innovative stereoscopic 3D computer technology, tailored to a range of nearly imperceptible transparent denture to complete the entire orthodontic treatment. No invisible orthodontic bracket orthodontic parts that require applying a corresponding pressure on dental needle the site of deformity under pressure in a long time slowly move to the correct position. Various malformations, different expected results, correct the installation to be used in different ways. Whether due to crowded teeth, there is a gap, or displaced teeth after conventional treatment, absolutely can regain smile. [1]
No bracket has two straightening teeth surgery advantages:
1, convenient: dental panoramic head measuring instrument accurately measured and calculated data misplaced teeth, one-time modeling, invisible braces can bring their own use at home, eliminating the pain of frequent referral.
2, invisible braces: braces are transparent, direct stuck deformity teeth, misaligned teeth quietly changed.

missing teeth bite

Generally missing teeth bite mainly refers to the remaining maxillary dental midline midline is not aligned with the teeth, jaw teeth down side to the inside, which not only affects the appearance of the teeth, but also for the normal functioning of oral and periodontal health and Oral health has a great impact. By U.S. dental correction to achieve good results. Reason

(1) early loss of teeth: there will be lack of space, resulting in crowded dislocation.
(2) bad habits: habitual thumb sucking, licking tongue. Jiao lips, bite things, stretching the lower jaw and the bad habit of swallowing, unilateral chewing habits, etc., can cause a variety of malocclusion.
(3) more teeth: teeth can cause multiple teeth, jaw morphology system dysfunction.
(4) Congenital missing dental needle teeth: more development and embryo reasons, mostly for lack of third molars phylogenetic degradation.
(5) deciduous teeth: Individual Dental shedding of deciduous teeth are not overdue, for following the eruption of permanent teeth can lead to the obstruction was an ambush, or misplaced eruption.
(6) Rujian tooth wear inadequate: because children eat too soft, so some nipples more teeth than other tooth wear, and thus higher arch occlusal surface, resulting in premature contact, causing the front or side movement, the formation of crossbite.
Missing teeth bite correction method can be used to solve, but very safe, according to each person's Gutta Percha Points situation to determine the correction techniques and methods, it is best to a regular hospital for consultation.

dental instruments and medical personnel microbial contamination status of iatrogenic infection

 1.1 Microbial contamination of dental instruments dental instruments in addition to being the patient's blood, saliva and other oral secretions pollution, the environment may be dental, medical staff hand contamination. HBV, HCV, HIV and other viruses is not only present in the blood, which can be discharged from the saliva contaminated dental instruments. Our hospital dental equipment HBsAg contamination rate fluctuations on 5% to 30%, urban individual dental clinic equipment on HBsAg positive rate of 37%, rural clinics dental equipment on HBsAg positive rate of 62%. dental Vacuum Former handpiece contamination of up to 5 × 10 4 ~ 5 × 10 6 cfu/cm2. The findings microbial contamination of dental instruments three major categories namely oral colonization flora, gastrointestinal pathogens such as Salmonella bacteria group, Escherichia coli group, Shigella dysentery bacteria, Pseudomonas group and fungi, times but also have paid close attention to blood-borne disease pathogens.

    1.2 medical personnel iatrogenic infection status dental instruments serious pollution not only endanger the patient, it also endangers the medical staff. Dental Clinic medical staff is one of many facing the unknown HBV, HCV, HIV infection or pathogen carriers come to treatment, their blood, saliva may contain pathogenic factor, so that dental burs patients and medical staff have the chance of infection. According to the medical staff of cold Taijun population survey found that hospital medical staff serum HBsAg positive rate of the general population is 3 to 6 times, and dental medical staff serum HBsAg positive rate is four times the other department staff. Foreign existing clinical data show that dentists HBV, HCV, HIV infection problems are present occupation. According to Japanese scholars Mochizuki widely reported that the Japanese dental practitioner HBV infection rate was 35.9%. Practicing dentist in the United States are also infected with HIV was reported.

dental instruments sterilization problems

 Dental instruments effective disinfection and sterilization for the prevention and control of nosocomial infections is a very important part in controlling HBV, HCV, HIV blood-borne diseases is particularly important and urgent. At present, China's current situation is not satisfactory disinfection of dental instruments, dental instruments dental chair sterilization, there are some noteworthy issues: (1) understanding the inconsistencies, preventive medicine specialists and clinical staff recognize there are differences. Because there are still re-treatment of light on defense issues, clinical staff rarely treatment of oral diseases and prevent other communicable diseases linked to rational and effective disinfection is also easy to be overlooked. (2) clinical staff, lack of sterilization of technical knowledge to grasp, not rational selection and use of existing disinfection technology. With traditional dental instruments sterilized in situ in situ use of the phenomenon. Such as dental handpiece with povidone-iodine, iodine, alcohol wipe or natural evaporation of formalin fumigation, so that part of the equipment can not reach through the mucous membrane thoroughly sterilized. After disinfection resulting viable bacteria may be detectable on the instrument, occult blood and HBsAg positive. (3) hospital leaders lack of knowledge on the disinfection of dental instruments, dental instruments sterilization equipment dental Vacuum Former configuration is not yet universal. (4) the lack of sterilization of dental instruments and regulations on the supervision mechanism. A wide range of commonly used dental equipment must be selected according to the situation of different disinfection methods and time. If you select the method of disinfection equipment improper or inadequate sterilization time can lead to cross-infection.

ultrasonic scaler Application Experience

 Ultrasonic Scaler is the use of a frequency of 20Hz or more ultrasonic vibration for scaling and scaling tartar, plaque dental medical instruments, and compared to traditional manual cleaning teeth, with high efficiency, speed, trauma, less bleeding , saving time, effort, etc.. Also its simple, does not require rigorous training, and good economic benefits, has been widely used oral clinical. I applied for many years, we found that the use of ultrasonic scaler there are many problems, are summarized below.

A disinfection problem

Clinically now mostly for dental instruments cleaning teeth dental care, teeth cleaning when infection if other diseases, is worth the candle. It is suggested that a conditional selection handles medical units, working head can temperature, high pressure sterilization scaler to ensure that no cross-infection between patients.

Two did not conduct systematic training

Use Scaler, should carefully read the instructions, in strict accordance with the user guide for installation, operation. According to the author of 30 dentists survey, only eight simple read instructions, they think scaler simple operation, without read the instructions, and in most cases by the nurse or advanced students, interns to do this work. Because of the scaler operating environment, operating conventional understanding is unclear, easy to damage the machine, but also easy injury patients teeth.

Three operations are not standardized

In clinical work, often encounter patients questioned ultrasonic scaler, ultrasonic scaler they believe will damage teeth, because they are direct or indirect information is ultrasonic scaler pain, sore teeth, some people will last a long time, In addition to the patient's own reasons, but also with doctors improper operation, such as the output power is too large, the working head too much pressure and so on. Correct operation should be: in the Scaler work before lowering power transfer large amount of water; water ejected from the working head, according to the dental hand piece working head using different transfer power to an appropriate value. Average output power should not exceed half of its maximum power, special circumstances need to increase the power, try to shorten the operation time, otherwise easily damage the teeth, but also easy to damage the work tool and transducer. Regulation of water right after the output power should be carefully adjusted so that the mist reaches 35ml/min so. At this point, you can begin work, the working head on the tooth surface, tooth angle of 15 ° or so, to light, steady, clean teeth do not stop slight head movement, so that the working head stones in layers under the rapid vibrations exfoliation. Note that the operation fulcrum Qingwo equipment, appropriate force. If the contact with the tooth surface is easy to produce heat too tight, feeling sore tooth discomfort, general pressure to 700dyne appropriate.

How to buy and replace Dental Equipment

  Oral treatment equipment used at work is very much needed new equipment are endless. In China, the dental equipment information is increasing year by year, dental equipment manufacturers and distribution companies, continued to provide dazzling advertising and promotions. For a dentist, how to buy and replace dental equipment really is not an easy thing. Now, many doctors opened his own clinic, buy dental equipment (including dental equipment replacement) is that they simply do not understand before, and now we must face the problem.
    In State Hospital (especially teaching and research institutions) jobs, buy new equipment, the standard is often convenient, efficient, equipment usage, price, reliability is often not the main criteria. But profit medical institutions in the purchase of equipment should first put "Do the best for me?" The problem first, and should be repeated to ask: how to use and maintenance of these products? Whether these products will make patients feel even more good? These products are better, dental hand piece more efficient, easier to use? Of course, these products must also consider the relationship between the cost and recovery. Any equipment manufacturers and distributors will use all means of promotion to open the market for their products, as the purchaser, must remain sober-minded, not to pretty pictures and favorable conditions impressed.
    Optional Equipment This work is not taught in school, the school provides only a single product for educational use. Dental dentists are direct users of the product, use of the product should be a comprehensive and in-depth knowledge and understanding. Many doctors in their experiences when they mentioned that they are mainly to understand the product by reading the advertisements found interesting product for samples after a test. If you feel good after use, they will find in the magazine relevant clinical reports and studies to further enhance understanding of the product, to the author and ask other doctors, acquire more information. Before deciding whether to buy products, they will work according to their own situation, after purchase for an assessment of the economic benefits. Familiar with product specifications provided by the manufacturer, through magazines and fellow deepen understanding of the product, if necessary, to participate in a hands-on learning classes, almost all experienced doctors are mentioned in the preparation.
Many doctors say that they are only being used when the products are not satisfied with the purchase and will consider the replacement product. Therefore, in the selection of products, their attention focused on the quality of some of the technical indicators, such as the impression material is much shorter fixed time, curing light illumination intensity value is more high, filling material is more small steps and so on.
    Some doctors for dental equipment always have great interest and high enthusiasm, so they tend to pick the product when positive, the product of the inadequacies of the more lenient. These doctors purchase and replacement of the product The bottom line is better than the present use of the product.
    In the market, dental equipment can be divided into mature, stage of development and new inventions three. The purchase and replacement of the product, it should not be too conservative. If the product has been known only in the time before going to buy and use, it is possible to miss a further explore the market, to attract more patients, enhance patient awareness of the opportunity.
    Dental equipment is dental instruments not household goods, their use object is the patient, their use and maintenance have a high technical content. This is why some manufacturers refuse to sell the product did not participate in specialized training to doctors causes. Now, more and more manufacturers and distributors are invited to hold classes, and some experts with hands-on training courses, introduce their technologies and products, which is a very good extension form. On the sponsor (or sponsor) who will have to completely get rid of economic benefits is unrealistic. But accountable to their fellow doctors introduce a technology and products, it does not talk about its advantages and benefits of trying to evade its shortcomings and precautions.
