Fixed partial denture abutment preparation

Members may have such a concept, or subgingival three shoulder the way, are advantages and disadvantages, for anterior teeth, conventional or subgingival shoulder, where I talk about the gingival shoulder preparation depth.

Subgingival the aesthetic effect of the shoulder is very good, but if improper because the production lead to periodontal disease, destruction of health Taibuyinggai In fact dentists in China, there may be a large part on this issue did not attract enough attention.

Crowns on the abutment in three aspects: First, the crown edge position depth; two crowns of abutment shoulder suitability of adaptation, now the requirement is 0.1mm error; three crowns contour.

Of course, on gingival sulcus depth shown in the patient population will be very different from the depth varies, especially the presence of gingival or periodontal disease patients, the gingival sulcus more than 2mm depth, the vast majority of people will less than 1mm. Crowns not to damage the epithelial attachment, this can cause gingivitis. Gingival should be used about 10g of force should not be excessive oppression of the gums in order to dental equipment emphasize the clarity of the gingival margin.

Also to be noted that the prepared tooth epithelial attachment in different aspects of the dental arc of the same shoulder prepared as flat, with the arc of the cemento-enamel junction.

The only strict compliance with it to avoid destruction of epithelial attachment and lead to gum inflammation, and then gingival recession. The shape of the shoulder should be compatible with the cemento-enamel junction.

For the right shoulder, porcelain crowns requirement is not 90 degrees, it should be 135 degrees bevel concave. The experimental results show that the What type of bad breath marginal fit of metal bladed for the best. This can be seen in many books, and specialized bur can prepare to come out.

What foods can I remove mouth odor?

In general, oral odor there is basically two reasons: 1. Oral unsanitary; 2. gastrointestinal dysfunction. And no matter what the reason, the culprit is the bacteria. If you go to the dentist to see a doctor, he may make two suggestions: First. Eat well, that is, pay attention to a balanced diet, adequate intake of protein and carbohydrates, and vitamin-rich vegetables and fruit. Second. And postprandial best brushing or flossing. Fact, there is a way to have the kinds of food is to remove bad breath expert, and prevent bad breath once again produce. They are:

Parsley this herb helps eliminate the smell of the mouth, especially cigarette smoke. If the hand is unable to find the parsley, coriander, mint can also play the role to remove mouth odor. In order to achieve better results, these things chewing the longer the good, or to tea drinking. In addition, several herbs mentioned above are also good for digestion.

Yoghurt latest research shows that, every day, yogurt can reduce the hydrogen sulfide content in the oral cavity, because this substance is the culprit of bad breath -. Time, the yogurt also can prevent the generation of harmful bacteria dental equipment in the mouth, these bacteria can cause gum disease or plaque. However, only natural yogurt has this effect, sugary yogurt not has this effect.

Fruits and vegetables rich in fiber include apples, carrots and celery. These vegetables and fruits help to secrete large amounts of saliva. Saliva not only moist mouth, but also to remove food residue attached to the tooth above or plug in the teeth. This food residue is one of the causes of mouth odor.

Containing a large number of vitamin C in food berries, citrus, watermelon and other foods rich in vitamin C can make the mouth to the formation of an unfavorable environment for bacterial growth. Regular intake of vitamin C is also very useful to the health of the Whitening toothpaste is long-term use can damage teeth gums. But we know that vitamin C from natural foods, rather than the intake of food additives because the additives may cause digestive function disorders.

Healthy teeth without porcelain

People often use "white" to describe the beauty of a person, but when expand the smiles on their faces, exposing the black and yellow missing teeth, no doubt a serious impact on personal image. Ever since, the older the more people on the requirements of the teeth not only stay in the absence of dental problems, neat, bright, white teeth have a common pursuit for many people.

Porcelain teeth, also called porcelain crown, the high temperature and pressure in the vacuum porcelain furnace made. The main principle is the mix of metal and porcelain, which is a metal, the outside porcelain real tooth surfaces will be rubbed off of 1.5 mm thickness of porcelain crowns outside in the real teeth. It is understood that this repair method, if the production well can be maintained at least a decade or even longer. Pursuit of reason: a short period of time has straight teeth.

Porcelain teeth a short period of time to save the teeth. Missing teeth and adjacent teeth healthy; abnormal dentition shape and not to do orthodontic treatment; dental caries or tooth defects, discoloration of the teeth were gray or brown. So, many people in droves, and dental equipment even a lot of people with healthy teeth pursuit of porcelain teeth.

Natural is the best, even if the technology no matter how good, porcelain teeth can not be comparable to natural healthy teeth. Inlaid porcelain teeth will not be able to eat excellent food, the teeth if there is no disease, and do not Cookin idea.

Not everyone can do porcelain teeth. If you have severe periodontal disease, loose teeth, bad, unfit for porcelain teeth. Teeth a lot of money, a lot of people to save money and pick the cheapest and profitable, some hospitals and Requirements of fixed partial denture dental clinics in an irresponsible manner as not eligible patients to install porcelain teeth, resulting in many patients the deterioration of the situation.

Second, is action? Regular visits to the scaling this is the most basic step to protect the teeth, it can protect the teeth from bacterial infections and remove dental plaster, it is recommended to go on.

Abutments conditions on the fixed partial denture

1. Crown: clinical crown should grow up as a fixed partial denture abutments, tilt, normal morphology and structure. After treatment does not affect the retainer retention and solid preparation, and can still be as the abutments, if caries or irregular shape. If the shorter the clinical crown of the abutment retainer retention and retention requirements but by the method of preparation of secondary solid shape (needle holes, box-shaped, canal or root canal retention of shape) or to increase the number of abutments can also be fixed partial denture abutments.

2. The root of the root: the fixed partial denture abutments should grow up thick or multi-root teeth; root should be solid, periodontal lesions. Alveolar bone loss does not exceed 1/3 of the root length by increasing the abutments to support and retention requirements, and still can be used as fixed partial denture abutments.

3. Pulp: pulp of the fixed partial denture abutments should be no lesions. If lesions after a thorough treatment, the side can be used as abutments.

4. Periodontal tissue: the periodontal tissue of the abutment teeth should be healthy and free from disease, have the enough periodontal reserves power to support the force of missing teeth. From the exterior view of the gums swelling, apical lesions, normal periodontal ligament, alveolar bone absorption or dental equipment absorption of not more than 1/3 of the root length on the X-ray film.

5. Abutments location: the location of the abutment should be normal, in order to enable the retainer to achieve a common place Road. Otherwise, the abutments twist or tilt the large cutting tooth structure during preparation of more, it is easy to hurt the pulp, and Do you think of straightening teeth can really change a person's appearance the force along the long axis of the tooth conduction could easily lead to periodontal tissue injury.

Electric toothbrush can not replace the scaling

Allegedly it combines the functions of electric toothbrushes and ultrasonic, brushes your teeth through ultrasonic vibration to remove tartar, plaque, and even propaganda can therefore reduce the frequency of scaling. The ultrasonic toothbrush is difficult to clean plaque, not a substitute for scaling.

Ultrasonic toothbrush can not replace the scaling

Oral dirt, there are three: one is the soft dirt, daily mouthwash can be removed; Yet another plaque, brush your teeth will be able to get rid of; a calculus must go through the manual scaling or scaling can get rid of. The ultrasonic toothbrush instead of scaling is unlikely. Inhuman color, the cleaning effect of ultrasonic toothbrushes may be superior to the general electric toothbrushes and toothbrush, to get rid of the plaque a bit role. Long-term attention to clean plaque and to prevent and reduce plaque formation. Ultrasonic toothbrush issued in the frequency, intensity, with the ultrasonic toothbrush in the hospital match can not be a substitute for professional scaling. Tartar has formed a hard, tightly attached to the teeth; ultrasonic toothbrush can get rid of. Teeth have been surrounded by saliva, you can not 24 hours of brushing your teeth, so the prevention of tartar is relative, not absolute prevention, ultrasonic brush your teeth and can not absolutely prevent plaque formation, annual or scaling once the.

Special populations should not use the electric toothbrush

Since the ultrasonic toothbrush no more than a magical effect, that toothbrushes how to choose? The most commonly used as an ordinary manual toothbrush, the purchase should be from three standard screening: 1. Brush head is not too much, and 2.54 ~ 3.18 cm length, width 0.79 to 0.95 cm for children's toothbrush to be smaller, in order to ensure that the flexibility in the oral cavity rotation. Two. Bristles after sanding treatment, to prevent the bristles are too sharp to damage the gums. 3. Bristles moderate hardness bristles strong will hurt your teeth and dental equipment gums, too soft brush does not clean. Certain special populations, you should use a special toothbrush. Orthodontic people in particular should pay attention to teeth cleaning, application of single beam toothbrush dolphin teeth to scrub; the non-carious defects and dental "soft" Dental erosion, soft bristles toothbrush, delay of tooth damage.

He also said that ordinary manual toothbrushes and electric toothbrush can clean teeth, the effect is much difference between the electric toothbrushes to clean more efficient, more suited to the need to increase the brushing interest of children, the pursuit of convenient white-collar workers, as well as the activities of the hand difficulties or people with disabilities. In addition, the larger the intensity of electric toothbrushes and the extent of tooth wear than ordinary toothbrush, dental defect of non-caries, abrasion, acid etching the disease, it is recommended not to use electric toothbrushes, including electric toothbrush with ultrasound.

Cultivation of the aesthetic elements of the treatment

At present, the implant treatment has been extensively carried out in the world, we implant treatment success criteria is no longer a simple combination of bone, dental implant can be so simple, but also implant denture with good aesthetic results. The aesthetic effect of the implant denture has become a key measure of planting success or failure factors. The aesthetic effects of planting treatment-related factors include the following:

1. Bone level: tooth loss in patients with or without obvious bone defects, and if so, to consider the bone graft in order to achieve good aesthetic results. Shortage of the west side of the adjacent teeth, bone height is the key to determine the papilla height.

2. Patients with the gums of biological type and amount of soft tissue around the implant: before treatment to determine the gums is a thin biotype thick biotype, is critical for the aesthetic effect of the late. When the need for soft tissue transplantation of soft tissue texture, the color with the original consensus also focus consideration.

3. Laugh line: when the patient smiles gums exposed, the aesthetic at higher risk.

4. The original dentition and missing teeth the size of the gap: the case of the original dentition, lack of clearance is too large or too small repair effect.

5. The choice of implant type and implantation of the number of explants: in aesthetics region, the implant types related to the effect of implantation. Some cropping systems used dental equipment in the aesthetic region, the three-dimensional position of the implant is very critical, if handled badly; the aesthetic effect will be very bad. Some system tolerance to some of the design to improve by late repair. Implant between the distance between the implant and natural teeth are the key factors related to the cultivation of long-term aesthetic results.

6. Three-dimensional position of the implant: implant a lot of explaining to the near and far to the location and crown and Understand the advantages and disadvantages of porcelain teeth root to the post-restoration effect is critical.

What are the hazards of resolve nickel-chromium porcelain teeth?

A porcelain tooth is a popular cosmetic dental way, while the Ni-Cr porcelain teeth in porcelain teeth, inexpensive and durable as porcelain teeth do.

Ni-Cr porcelain teeth are real non-precious metal ceramic crowns, has good biocompatibility, and now has a wide range of applications in the field of prosthodontics.

Used in dental Ni-Cr porcelain teeth as early as 1929, because the higher cobalt content, good corrosion resistance, and porcelain bond, contain more chromium, its high melting point alloy and package there is a certain reaction in the buried material. Harm the human body is non-existent, and the safe, reliable and reasonably priced, stable performance.

Advantage of the Ni-Cr porcelain teeth with excellent value for money, with the best biocompatibility, excellent marginal degree, unique and beautiful charm, and good transparency, excellent color, shape and more realistic. And dental equipment hard to not collapse porcelain, became the new darling of the consumers. Severe tetracycline dental fluorosis, abnormal teeth, discolored teeth can be repaired by this method.

However, due to the nickel-metal elements in the Ni-Cr porcelain teeth in the oral environment, due to the instability of the nickel-metal elements, the time has become easy freed, causing the gums gray line, some of their patients allergic to nickel metal elements in patients with a friend anaphylaxis have been reported in the installation of the Ni-Cr porcelain teeth.

But overall, the hazards of the Ni-Cr porcelain teeth or Deciduous teeth root canal gutta percha use plombage not. As long as it is produced in the oral hospital after formal professional sophisticated Ni-Cr porcelain teeth or can be assured that use.

Maxillary third molar root canal morphology: Maxillary Third Molar

Loss of the maxillary first and second molars is often the reason for considering the third molar as a strategic abutment. The other indication for endodontic treatment and full coverage is a fully functioning mandibular third molar. Careful examination of root morphology is important before recommending treatment. Many third molars present adequate root formation, and given reasonable accessibility, there is no reason why they cannot remain as functioning dentition after endodontic therapy. The Radicular anatomy of the third molar is completely unpredictable, and it may be advisable to explore the root canal morphology before promising success.

As an alternative to conventional hand instrumentation, the use of engine-mounted files in reciprocating hand pieces may simplify the problem of accessibility. Preserving instruments helps guide them through tortuous canals. For visual and dental equipment mechanical convenience the access may be overextended slightly with the knowledge that full coverage is the mandatory.

All caries, leaking restorations, and pulpal calcifications must be removed prior to instituting treatment. Some third molars will have only a single canal, some two, and Men whitening teeth Raiders most three. The orifice openings may be made in either a triangular arrangement or a nearly straight-line.

Inspection and methods of correction needs to be done

Correction normally takes to do the following checks:

(1). Teeth India: diagnosis and design for a doctor right or wrong situation, and in the subsequent course of treatment for comparison checks.

(2). Photo: Before treatment, the doctor to be routine for patients according to facial pictures and photos for comparison later with the end of treatment.

(3). X-ray examination: patients with conventional shooting cephalograms and panoramic radiographs.

(4). The development of treatment programs: doctor according to the models, photographs and X-ray, Medical - education network collected after the measurement, calculation, diagnosis, type of malocclusion, and to develop a detailed treatment plan. The doctor then explained to the patients and family members of patients to treatment programs, to seek the views of patients and their families. Treatment program is determined, patients or family members to dental equipment sign a consent form.

(5). Specific course of treatment.

(6). after treatment, remove the appliance, wear a retainer.

Correction:

Appliance activities: general commonly used in the deciduous dentition of simple malocclusion correction, or with fixed orthodontic appliances for correction. Patients that they can pick wear.

Fixed sedan governance: the most commonly used appliances. Patients themselves can not pick to wear.

Functions sedan governance: mainly used in the mixed dentition or just for the finished tooth is still in the peak period of growth and Comprehensive oral health knowledge development of Children's Hospital - education network collected using a functional appliance can correct malocclusion bone.

Orthognathic Surgery: severe maxillofacial deformities, such as maxillary protrusion, maxillary retrusion, mandibular protrusion, mandibular retrusion, a simple correction can not solve, you need surgery and orthodontic Joint Correction.

Children teens start brushing teeth?

We can usually three phases brushing training for young children.

Phase I: When the baby began when the first tooth, which is about six months necessary to give the baby brush your teeth.
