The current methods of dental prosthesis include fixed bridge, removable denture (movable denture) and dental implant.

The common problem of the elderly is that the missing teeth are not repaired in time, resulting in the tilting of the adjacent teeth, resulting in the loosening of the adjacent teeth, which may eventually lead to the loss of the remaining teeth, affecting eating and oral health. The elderly must consult a doctor before dental prosthesis, and wear a dental crown in time for restoration.

Fixed bridge

The fixed bridge belongs to a fixed denture, the basic principle is to use one end of the missing tooth or one end of the natural tooth as the abutment, prepare a fixed body on it, make it form a body with the tooth, and then use a cement to combine it with the abutment, the patient can not take it off.

Merits and demerits

The main advantages are good retention and stability, when the chewing function is performed, the fixed denture and the abutment form a new functional whole, which is relatively stable and does not shift, and the chewing efficiency is very high. The fixed bridge support function is good, and its combined force is all borne by the abutment and the periodontal tissues below it, and the supporting force is relatively large, and its combined force conduction mode is similar to that of natural teeth. High comfort, the volume of fixed dentures and natural teeth are similar, there is no particularly obvious foreign body sensation, more easy to adapt; The fixed denture does not need to be removed after wearing, which is convenient to use, will not affect the patient's language function, and will not produce nausea and other feelings; The color of fixed dentures is close to that of natural teeth and meets aesthetic standards.

The main disadvantages are the large amount of tooth grinding of fixed abutment teeth; The manufacture of fixed Bridges is difficult; On the other hand, fixed Bridges have a more stringent range of adaptation, and not every patient with missing teeth can accept it, so a corresponding diagnosis and treatment plan must be developed.

indication

(1) The number of missing teeth: usually 1 to 2, if more than 2 missing teeth, the interval missing teeth is better.

(2) The location of the missing tooth: there are natural teeth in the missing tooth area, and there is normal periodontal tissue.

(3) Good abutment condition: the crown height is moderate, the root is thick and stable, the periodontal tissue is healthy, there is no excessive distortion and displacement, and the injured teeth need adequate root canal repair.

(4) Occlusal relationship: there is a large distance between the alveolar crest of the missing tooth area and the opposite jaw teeth, the opposite jaw teeth have no extension, and the adjacent teeth have no inclination.

(5) Dental groove repair in the missing tooth area: usually after 3 months of removal, the alveolar ridge in the front tooth area should not absorb too much, so as to avoid adverse consequences, and a health bridge can be set up in the rear tooth area.

(6) Age: The age of the patient does not have much impact on the structure of the fixed bridge denture, but if the patient is too young, it is likely to cause pulp damage when the abutment is prepared. If you are too old, the abutment will become loose due to too much force due to the contraction of the periodontal tissue.

Removable denture

Removable partial dentures are supported by natural teeth, mucous membrane and bone tissue under the base, and are fixed by the fixation between the fixator and the base. The alveolar ridge, jaw bone and surrounding soft tissue are repaired by artificial teeth, which can be removed by the user independently. The application range is extremely wide, from individual tooth loss to complete tooth loss can be used.

The main advantages are wide application range and less tooth tissue. Patients can remove and wear themselves, easy to clean; Simple production, the treatment process is painless; Low cost, easy to repair. The main disadvantages are large size, strong foreign body sensation, sometimes even affect pronunciation, cause nausea, its stability and chewing efficiency are not as good as fixed denture, if there is an unreasonable design of denture, poor production quality or poor oral hygiene habits of patients, it may also bring abutment damage, mucosal ulcer, dental caries, periodontitis, alveolar bone accelerated absorption and other adverse consequences.

If you want to do removable dentures, you should choose the brand, type and production method suitable for your dentures under the guidance of a doctor, and you can not decide at will. Before the denture restoration, the necessary examination should be carried out to ensure the function and quality of the denture.

The elderly will feel some discomfort when they first wear dentures, such as strong foreign body sensation, affecting pronunciation, increased saliva, nausea and retching, mucosal tenderness, etc., but don't be too nervous, you can adapt slowly, please seek medical attention in time if necessary.

Dental implant

Dental implants are made of pure titanium materials with good bone compatibility, which are made into cylindrical or other shapes that are highly compatible with human bones, and placed into the alveolar bone in the missing tooth area through a small operation, which makes it closely combined with the alveolar ridge in about 3 months, and then the crown bridge is prepared on it, providing a new way for the clinical treatment of missing teeth. Dental implants have strong support and can perform chewing functions for patients just like natural teeth.

Merits and demerits

Dental implants have the advantages of high comfort, strong aesthetics, durability, no need to grind teeth, etc., and have become the first choice for more and more patients with missing teeth. The disadvantage of dental implants is that the repair cycle is long, usually 4 to 6 months; Compared with removable denture, the cost is higher and the recovery period is longer. It requires patients to avoid diseases such as hypertension, heart disease, diabetes and blood clotting disorders.

indication

Patients with one or more missing teeth who are not suitable for or unwilling to undergo traditional denture restoration; The alveolar ridge is severely absorbed so that it is too flat or blade-like, the muscle attachment position is too high, and the tongue is too large or too mobile, which affects the retention of patients with removable dentures. People who are not used to wearing removable dentures for psychological or physiological reasons or have nausea or vomiting reactions due to base stimulation.

Precautions for dental prostheses

(1) The elderly must go to the regular hospital when dental prostheses, because there are many small clinics under the guise of low prices, often there will be technical irregularities, poor quality and so on.

(2) The elderly must be carried out under the guidance of a doctor, because some elderly people do not understand the principle and blindly carry out dental prosthesis, which will not only cause damage to the teeth, but even cause certain harm to the body.

(3) The elderly need regular check-up after dental prosthesis, usually half a year or once a year, to prevent the acceleration of jaw resorption caused by residual dental caries, periodontitis and occlusal abnormalities.

(4) The elderly should pay attention to dietary problems after dental prostheses, and can not eat too hard food and spicy and irritating food. Because older people's chewing ability is weakened, poor eating habits can lead to residual dental trauma, accelerated resorption of alveolar bone, and loss of dentures.

(5) The elderly should pay attention to oral hygiene and cleaning after dental prostheses. The elderly generally have gingival atrophy, dental calculus, bad breath and other problems, if you do not pay attention to oral health problems, it is easy to lead to gingivitis, periodontitis and other diseases, accelerate the loosening and loss of remaining teeth.

(6) The elderly should pay attention to maintaining a good emotional state after dental prostheses, because emotions have a very large impact on human health.

(7) Elderly people suffering from chronic diseases such as high blood pressure, heart disease, diabetes should be careful to choose dental prosthetics.
