What's the difference between false teeth and dental implants?

Dentures Dentures are what people often call "dentures". Just as "artificial legs" and "artificial limbs" are called "artificial limbs", "dentures" are teeth that do their duty for human beings. Medically, it is a general term for prostheses made after partial or all teeth of upper and lower teeth are missing. Dentures can be divided into movable dentures and fixed dentures. Fixed dentures (commonly known as "fixed dentures") cannot be taken and worn by patients themselves, while removable dentures (commonly known as "removable dentures") can be taken and worn by patients conveniently.

material

(1) plastic teeth. Chemical connection with denture base, mostly using finished teeth, can also be customized. Plastic teeth are not easy to fall off and break, and can be polished at will to adapt to different gaps in patients' missing teeth. But the hardness is poor, easy to wear, and the chewing efficiency is also poor. Hard plastic teeth, which have been widely used in clinic, have better wear resistance than ordinary plastic teeth.

(2) porcelain teeth. It is connected with the base through nails or holes on the tooth surface, which are all finished products. Porcelain teeth are hard, dense in texture, not easy to wear, high in chewing efficiency, good in luster and not easy to pollute and change color. But it is brittle, easy to crack, and can't be polished at will or over-polished. Therefore, it is suitable for people with large gap, continuous loss of multiple posterior teeth, large gingival distance (distance from occlusal surface to gingiva), full alveolar ridge in the missing area and healthy periodontal condition.

(3) Metal (lingual) facial teeth. Refers to the lingual surfaces of the posterior teeth and anterior teeth of artificial teeth, which are made of different metals by casting or hammering, and connected with plastic teeth by metal retention devices. Because of the high hardness of metal, it can bear a large bite force and is not easy to break and wear, but it is difficult to grind and dress. Metal-faced teeth are suitable for those whose teeth are elongated or whose adjacent teeth are inclined or displaced to the edentulous area, resulting in too small edentulous space and too low gingival distance. In addition, various methods are used to improve the performance of dentures, such as embedding metal parts in plastic teeth to increase the wear resistance of dentures. In addition, cast metal mesh steel bars can be embedded in plastic teeth to prevent biting.

(4) metal teeth. In order to prevent the longitudinal fracture of artificial teeth, if the gap between missing teeth is too small or the gingival distance is too low, metal teeth or metal teeth and brackets and clasps can be integrally cast to achieve the purpose of beauty and durability.

Advantages?

1, fixed denture? Comfortable and high chewing efficiency?

2. Beautiful and durable, with a general life span of several decades?

3, does not hinder the movement of the tongue, does not affect the identification of food taste.

4. removable dentures? Strong self-cleaning ability, which is beneficial to the cleaning of residual teeth?

5. The clinical operation is simple, and the patient has no discomfort during the operation?

6, the cost is low, even if the complete plastic denture does not exceed 1000 yuan?

disadvantaged

1, too many teeth need grinding.

2, the cost is high, which is several times that of general removable dentures.

3, poor self-purification ability (not picking by yourself, easy to miss food.

4. If there are many missing teeth, it can be seen that the metal clasp is not beautiful.

5, foreign body feeling is very strong, many people can't stand it.

6, need to take it off every day, the process is cumbersome, which is not conducive to social activities. Movable dentures are generally not counted by the number of teeth.

Dental implant is a kind of restoration method of missing teeth, which supports and retains the upper teeth by implanting the lower structure of bone tissue. It consists of two parts: a lower supporting implant and an upper denture. It uses artificial materials (such as metals, ceramics, etc.). ) make implants (generally similar to the shape of root), implant tissues (usually maxilla and mandible) through surgery and obtain firm retention support from bone tissues, and connect and support upper tooth restorations through special devices and methods. Dental implants can achieve the same restoration effect as natural teeth in function, structure and aesthetic effect, and have become the first choice for more and more patients with missing teeth.

material

The material of dental implant is divided into two parts: root material and crown material. Dental crown materials can be handled flexibly according to patients' wishes, while root materials are strictly regulated. In the long historical exploration of human stomatology, many materials have been used for root implantation, such as gold, precious stones, lead, iron, iridium, platinum and silver, as well as porcelain, rubber and ivory. With the development of modern industry, many metal materials with high strength and good corrosion resistance have appeared, such as cobalt-chromium alloy, titanium and tantalum.

superiority

1, its chewing function is much better than many traditional dentures.

2. It has strong retention and stability and is rooted in the patient's mouth like a real tooth.

3, there is no damage to the natural teeth on both sides.

4. There is no need for the necessary base and clasp of removable denture, and there is no dull feeling and discomfort caused by large-area plastic base;

5, small size, no metal exposure, beautiful appearance, which is conducive to keeping the oral cavity clean and hygienic. ?

disadvantaged

1, the course of treatment is longer than that of traditional prosthodontics, generally 3 months.

2, the cost is high, about 1w each.

3, the patient's bone requirements are high.
