High score for help: the problem of installing dentures in the elderly

An old man who is adjusting new dentures said that he used to use them after installing dentures. I didn't expect it to be more comfortable to adjust every few days.

The old man told reporters that his surname is Chen, 7 1 year old, and he lives in zhoushan road. In 2002, he went to the hospital to install false teeth because many teeth were decayed. At that time, the newly installed dentures were very uncomfortable, and they felt pain from time to time and could not make them work. But Mr. Chen doesn't want to bother going to the hospital, so he will make do with it, and eating at ordinary times is also very affected. Later, false teeth often fell out. At the beginning of this year, Mr. Chen reinstalled his dentures. Xin 'an's dentures are more comfortable after being adjusted by doctors, and Mr. Chen is more satisfied.

Xu Gui, an attending physician in the dental clinic of Luoyang Hospital, said that the elderly are afraid of trouble and can tolerate it. Even if it is inappropriate, most of them will use dentures. In fact, from a professional point of view, the installation of dentures has an adaptation period, which needs to be constantly adjusted according to the situation. Under normal circumstances, it is normal to install a pair of dentures and go to the hospital for adjustment three to five times within six months. It's good to get used to it after wearing it for a year. If you ignore the adjustment after installing dentures, it is likely that the teeth will be unevenly stressed during chewing, and symptoms such as bleeding and toothache may occur, and tooth blockage may occur, which will accelerate the decay of real teeth.

Dentures should be replaced every five years.

Dr. Xu said that dental implants for elderly friends often do not require appearance, but pay more attention to economy and practicality. However, many elderly people often expect "once and for all" and hope that "a pair of dentures will be worn to the end". This concept and practice is incorrect.

Take the patient Mr. Chen, whom the reporter met, as an example. According to the doctor, when he visited the doctor this time, his upper dentures and gums were not tightly closed, the original dentures had worn about 1/3, and the alveolar ridge was seriously damaged. The false teeth of the lower teeth are loose, and the real teeth wear more. Dr. Xu said that this has a lot to do with Mr. Chen Lao wearing a pair of false teeth for too long.

Dr. Xu said that under normal circumstances, a pair of dentures needs to be replaced in time after about 5 years of use, but many elderly friends hope that "a pair of dentures will stick to the end", and some elderly patients even wear a pair of dentures for more than ten years.

In fact, wearing a pair of dentures for a long time will accelerate the absorption of alveolar ridges in the mouth, and the gums will become lower at an accelerated rate. As a result, the denture has no fixed position and it is very difficult to install the denture. Therefore, it is very important for elderly patients to consider replacing a new tooth every five years according to the examination.

Don't wait until all your teeth fall out.

Dr. Xu said that in 2002, before Mr. Chen went to the hospital to install false teeth, all his upper teeth had fallen out. His practice is very representative in the elderly patients with dental diseases, but it is also very wrong.

Dentists say that even the most advanced dentures can't compete with people's own real teeth. When the teeth of the elderly are decayed and fall off, don't "wait for the loose teeth next to them to fall off before installing false teeth." Because when the teeth fall off, the oral tissue will be unevenly compressed when chewing, which will increase the gap between the teeth and accelerate the decay and fall off of the real teeth. The more real teeth, the shorter the adaptation period after denture installation, and vice versa.

Therefore, repairing the lost teeth in time is helpful to prevent the teeth of elderly patients from falling off in advance, reduce the burden of gastrointestinal tract, keep the pronunciation clear, and is more conducive to beauty and health.

What do I need to prepare for denture fitting?

Many people think that dentures can be installed at any time when teeth are lost, but experts remind that to install dentures, we must first be prepared.

It turns out that the restoration of dentures requires that the bone and soft tissue bearing the denture base or containing artificial roots must have good conditions, so that patients can wear dentures effectively for a long time. Some alveolar problems will affect the function of denture and the success rate of dental implant, such as low alveolar stenosis, alveolar bone defect, alveolar bone lesion caused by some chronic inflammation of root, alveolar bone absorption caused by periodontitis and periodontal bone defect.

If the above problems are not solved, the patient's oral cavity will be painful, or the denture will loosen or fall off due to insufficient contact area, which requires oral surgery before denture repair, including alveolar bone trimming, bone carina trimming, correction of too short lacing, deepening of labial and buccal groove, elevation or widening of alveolar ridge, etc.

What conditions do the elderly need to install dentures?

Denture is called denture in medicine. There are two traditional methods of denture implantation: fixed and movable.

Fixed denture is to use good teeth adjacent to missing teeth to fix denture, and patients do not have to bear it themselves. When extracting teeth, the adjacent good teeth with missing teeth should be ground off, replaced with abutment teeth, then put on braces, then connect the two ends, insert dentures in the middle and fix them. Fixed dentures are small in size, have no foreign body sensation, and are easy to get used to after being put in the mouth. And its chewing function has recovered well, like a real tooth.

The condition of fixed denture is high. The age is generally 25-55 years old and one or two teeth are missing. The adjacent true teeth are high enough, the root is stable, the tooth tissue is healthy, the tooth position is normal, and there is no inclination and torsion. You can consider installing fixed dentures. However, children, people with atrophic periodontal tissue, loose teeth and oblique dislocation cannot install it. Your gums are not suitable for atrophy.

The removable denture is composed of denture on the base and elastic metal hook, which can be freely taken and worn. It has a wide application range and can be considered by most patients. From missing teeth to full-mouth teeth, even if the adjacent teeth at both ends are not strong, they can be installed. Its advantages are less grinding teeth, removable dentures, cleanliness and good oral hygiene. Its disadvantages are that the adaptation time after inlay is a little longer, the removable denture is bulky, foreign body sensation, some of which will affect pronunciation, poor stability, and the recovery of chewing function is worse than that of fixed denture.

Method and price of installing dentures

At present, the new methods of installing dentures can be summarized as veneer, precision attachment denture, telescopic denture, magnetic retainer denture and implant denture. Various dentures have different indications, which are briefly introduced below.

Veneer repair

Veneering is to cover the lip surface of the front teeth with non-metallic materials, so that the color and shape of the original teeth are improved. Veneering can be divided into light-cured resin veneer (not a new method) and porcelain veneer according to the different materials used. Light-cured resin veneer has a good shading effect and a certain hardness, and it is simple to operate, moderate in price and easy to popularize, but the color is not natural enough, the long-term effect is not good, and it is easy to change color and fall off. Porcelain veneer has good gloss, vivid color, wear resistance and corrosion resistance. However, due to improper design and operation, it is easy to fall off and needs to polish a certain amount of tooth tissue, which is only compared with light-cured resin veneer, while porcelain crown needs to polish more teeth. Porcelain veneers are complex and expensive, each piece is about 1500 yuan.

Generally used for anterior teeth, such as enamel hypoplasia, dental fluorosis, tetracycline teeth, discolored teeth, oversized teeth, etc. Such patients can also be restored with porcelain crowns.

Precision attachment denture

Usually, the attachment is composed of yin and yang. One part is fixed on the fixed tooth or implant in the oral cavity, and the other part is connected with the prosthesis to form a whole. The retention is generated through the high embedding and friction between them. It is one of the repair methods of fixed-movable joints.

Advantages of attachment denture:

1. Beautiful, avoiding the exposure of metal clasp of traditional removable denture.

2. Good retention and stability. The retention force is greater than that of the clasp.

3. Protect the abutment to avoid the lateral pressure of the snap ring on the abutment. Generally speaking, two or more abutments are combined to place attachments. Therefore, the chewing pressure on abutment is dispersed and more balanced.

4. Protect the health of periodontal tissue. Attachment denture can keep residual roots and crowns in the mouth as abutment teeth, exert its physiological potential and slow down the absorption of alveolar bone.

But the attachment must have sufficient crown height and good oral hygiene environment. If the crown height is low and the occlusion is tight, it is impossible to place the attachment yin and yang. At the same time, the manufacturing process of accessories is complex, difficult, high in precision and expensive, and the single jaw costs 3 000 ~ 65 438+00 000 yuan. Patients should choose carefully according to their own situation and the guidance of doctors.

1. Repair all kinds of dentition defects that do not want to expose metal clasp, especially repair unilateral and bilateral posterior tooth free loss.

2. Patients with complete dentition loss and obvious alveolar ridge absorption.

Telescopic crown denture

Telescopic crown denture refers to removable denture with telescopic crown as retention device, also known as double crown. As the name implies, this kind of tooth retention device consists of two crowns, namely the inner crown and the outer crown. The inner crown is firmly bonded to the abutment (natural tooth), and the outer crown is integrated with other components of the removable denture. Denture produces retention force through the inlay between the inner crown and the outer crown, which makes the denture achieve good retention and stability. Telescopic crown denture has the following advantages.

1. Protection of residual teeth.

The application of telescopic crown restoration can maximize the retention and utilization of residual roots, crowns and even teeth with severe periodontal disease. For the loose teeth with periodontal disease, the crown of the overgrown teeth is cut off by telescopic crown restoration, and the clinical crown-root ratio is improved, so as to keep the loose teeth. This not only eliminates the pain of the patient's tooth extraction, but also retains the feeling of the tooth itself, and the denture is realistic. At the same time, this kind of denture can evenly distribute chewing pressure, reasonably adjust the load of periodontal tissue, and it can be removed, which is very easy to clean teeth and gingival tissue and meets the health requirements of teeth and periodontal tissue.

2. The retention force is durable and the damage to abutment is small.

For ordinary removable dentures, the retention of clasp will gradually decrease with the increase of tooth extraction times. The sleeve crown is obtained by the close embedding between the inner crown and the outer crown, and its retention force can be maintained for a long time as long as the tightness is not reduced. At the same time, the abutment is balanced, which can avoid the lateral force caused by the removal of the clasp. Therefore, there is little damage to the adjacent teeth.

3. Comfortable and easy to maintain.

Telescopic crown denture can greatly reduce the area of the base, make the denture smaller, feel less foreign body, and make the patient feel comfortable and easy to adapt.

However, the disadvantage of this kind of restoration is that it needs to polish a lot of tooth tissue, and the remaining teeth need root canal treatment. External crowns are generally restored by baking plastic, which is not as natural as porcelain teeth. Moreover, there are metal wires exposed in the neck of the teeth, which is not conducive to aesthetics. Dentures are expensive, ranging from 5000- 1 10,000 yuan per jaw. Therefore, when choosing telescopic denture, we must combine our own economic conditions and oral conditions, refer to the doctor's advice and choose carefully.

1. Some patients who are not suitable for fixed denture restoration and are unwilling to design clasp denture;

2. Patients with periodontal disease with dentition defect and severe alveolar bone absorption;

3. Restoration of dentition defect of a few teeth.

Magnetic retained denture

Magnetic retainer denture consists of a pair of heteropolar magnets. One pole is fixed on the tissue surface of denture base, which is called retainer, and the other pole is fixed on the root, which is called armature. When the denture enters and exits the cavity, the two poles attract each other to produce magnetic attraction, thus realizing retention.

Characteristics of magnetic attachment denture;

1. Its holding power is very strong, the holding power of a pair of magnets is about 600g, and the holding power is lasting.

2. The contact surface between the two poles of the magnet is smooth and can move relatively freely, which can minimize the lateral force on the abutment and protect the abutment.

3. Use the attraction of the magnet to replace the retaining ring, and no metal is exposed. It is not only beautiful, but also makes up for the bad influence of clasp on abutment.

4. The use of magnetic retainer can reduce the base area and reduce the foreign body sensation.

5. Prosthesis with magnetic device is very convenient to put in and take out, and is not limited by any direction.

6. Compared with other special retainers, the magnetic retainer denture is simple to make and easy to clean.

indicate

1. Complete dentition loss

Using a small number of residual teeth to place magnetic retainers to make complete overdentures can enhance the retention and stability of maxillary and mandibular dentures, which is difficult for traditional complete dentures to achieve. Usually, two kinds of magnetic retention systems are used in single-jaw overdentures, and the more dispersed the position on the dental arch, the better.

2. Partial dentition loss, especially distal or proximal free loss.

The use of magnetic retainer can eliminate or reduce the large torque produced by clasp on abutment.

In a word, the magnetic retainer system provides another effective restoration method for patients with dentition defect and loss, and the price is about 4000 yuan.

Implant denture

Implant denture is to implant titanium artificial root (implant) into the alveolar bone in the edentulous area, and install porcelain crown or metal crown on the artificial root to repair the edentulous tooth (8 000 ~ 65 438+00 000 yuan each).

The conventional restoration method of missing teeth is: the fixed denture needs to polish the natural teeth at the adjacent two ends and fix the denture on the adjacent teeth. Removable dentures need to remove several teeth to put the brackets together to bear the missing force, and they need to be removed every day to feel foreign bodies. Implant denture does not need to polish adjacent teeth, so it has no damage to adjacent teeth, and it is fixed and does not need to be pulled out every day. When the implant denture performs chewing function, the pressure is directly transmitted to the alveolar bone through the artificial tooth root, and its supporting function is similar to that of natural teeth, so patients will not feel strange. In addition, for patients with complete tooth loss, the retention of complete denture depends entirely on the soft tissue adsorption between denture and alveolar bone surface and the action of atmospheric pressure. However, some patients have severe alveolar bone atrophy, poor retention of dentures and easy to fall off when talking and chewing food. If conditions permit, complete dentures can be fixed with implants by implanting in alveolar bone.

indicate

Theoretically speaking, implant denture can be applied to the restoration of various tooth defects. But not all missing teeth are suitable for dental implants. First of all, dental implants need surgery, and people who have systemic diseases such as heart disease, diabetes, hematological diseases, hypertension (uncontrolled), kidney disease and so on should not do it. Osteoporosis of alveolar bone or excessive absorption of alveolar bone due to periodontitis and tooth loss for a long time, and insufficient residual alveolar bone can not support artificial root, which will lead to implant failure. In addition, the gap between missing teeth is small and it is not suitable for implant restoration.

{According to the dentures you choose to install, it is only credible to ask the local dentist about the specific charges. }
