1. What is dental implant?

A dental implant is a prosthesis for replacing missing teeth. The natural tooth crown and root, crown is covered with white enamel visible inside the mouth part. The root part of the crown is to support and further jaw part. The root is a part of the tooth, the implant is an effective substitute for natural root. The implant usually consists of three parts: one is the implant itself, is directly into the part of the jaw; two is the base station, is a device connected with implant crown; three clinical crowns or dentures. Nowadays, the implant material is mainly titanium, which has good biocompatibility, ductility and durability, and is the only metal that can be combined with bone tissue. The way it is connected with the bone is "bone union".

2, what is bone union?

The working principle of the implant is called osseointegration". Bone cells and implant surface titanium contact, and will eventually implant embedded in the jaw, this process is the earliest by the Swedish researcher Per-Ingvar Branemark, discovered in 1960, through the surgical operation, the implants in the maxilla, so as to achieve the purpose of "bone integration". The implant and the upper part of the crown, can satisfy the design and function of different. That can be used for repairing missing single tooth missing, even can also repair the whole arch. The restoration of the denture is usually matched with the natural enamel color to provide a perfect natural appearance and a beautiful smile.

3, the implant for me?

For most people, when you start reading this article, you have a missing tooth. Dental implant is an ideal material for the repair of the missing teeth caused by trauma or caries. Dental implant for:

Single tooth loss - can avoid doing a fixed bridge

A few missing teeth can be prevented from fixed or partial denture repair

And lack of full dentition denture, can avoid doing

A dental implant, you can eat any food to eat, because the implant denture can withstand strong bite force but also stable enough and beautiful approximate natural teeth, can restore the maximum beautiful smile.

4, how can I know if I am suitable for planting repair?

If you think the dental implant for you, then contact your dentist, make a comprehensive evaluation for you, but if the planting area with untreated teeth, gums or jaw disease, is not suitable for planting, planting will reduce the success rate of the operation, at the same time will affect the implant's binding force and stability.

Therefore, the need for a thorough examination of the full dentition (including teeth and jaw), but also need to evaluate the condition of occlusion.

5, early inspection

What kind of situation is better in the inspection process?

A dentist or implant doctor will be exposed to X-rays, with a focus on the area to be grown. In general, clinicians by X-ray carefully check the remaining teeth and jaws of the area to be treated. Many dentists have taken a curved surface to better show all the teeth and jaws of the upper jaw, as well as the diagnosis of some pathological diseases. Surface radiographs can also be used to assess the relationship between available jaw height and other anatomical structures, all of which provide a complete assessment of the next planting.

CT scan

At this stage, the most accurate imaging analysis is CT scanning, also called CAT scanning. Dentists take CT films to diagnose, analyze, and guide treatment plans for implant surgery. You may be more likely to become a radiologist in the process of understanding the diagnosis.

There is also a CT scanning technique called cone beam CT (CBCT). Able to provide similar images, and can easily be transformed by software and used by clinical dentists. CBCT can produce fewer doses of radiation, and it is easy to watch in radiology or even in the undergraduate class. Various types of CT can provide detailed, three-dimensional images, and precise anatomical structure can be used to measure the height and width of jaw and adjacent surgeons must be particularly careful (such as the maxillary sinus and inferior alveolar nerve).

Because the radiation dose is all additive, excessive radiation generated by the potential hazards have been reported in the literature, so as to improve the accuracy of image diagnosis, must take control of radiation dose in dangerous range at the same time as much as possible to reduce the number of exposures.

Additional inspection

Other diagnostic studies are also necessary for implant surgery. A good periodontal examination, need to observe the presence of gum disease, if there is a gum disease, should develop an effective treatment plan. Similarly, each tooth is as important as the treatment of caries and other dental diseases.

All aspects of dental impression in planting treatment is necessary, and can evaluate the state of occlusal position between the implant and Yu Liuya and dental arch, photo is also the auxiliary treatment and record the whole plant in each stage must.

6, how to place the implant?

Most dental implant surgery is performed in a dental clinic or a hospital clinic. Most have local anesthesia, but now there is another form of anesthesia, known as sedation anesthesia or intravenous anesthesia. A number of additional operations, such as bone grafting, can be performed in two phases, or at the same time as implants. Each implant surgery is not the same, it is closely related to the clinical environment, the patient's own situation and the technical level of the surgeon.

7, why is the surgical procedure to be divided into three steps?

At present, the most widely used operation is staged surgery. The first stage involves the surgical implantation of the implant (instead of the root) into the jaw, which can effectively protect the implant during healing. At the end of the treatment, surgical removal of the implant surface is required.

In the second phase, the surgeon first examined the bone healing of the implant, and then connected some form of pile through the gum to the mouth. Can also be used for lathe processing can also be formed in the traditional laboratory processing. Gingival healing around the abutment and the formation of dentin sleeve or dentin collar, in order to facilitate the dentist's final denture repair.

It has been proved that it is feasible to implant abutment at the same time. Although there are some limitations, there is no need for a two stage operation, thereby reducing the risk of excessive exposure to the implant. But it still takes a long time for bone healing.

At the stage of perfect bone healing, the healing abutment needs to be able to support enough bite force. Once the implant is well healed and bone formation has been formed, the healing abutment will be replaced in the final repair. The final repair process is the use of the final denture with the implant that has been formed.

8. What is the total success rate of dental implant?

Although there are a number of clinical and laboratory studies, dental implant technology does not have a 100% success rate. However, since the beginning of the use of planting technology, the success rate has increased significantly, and now can be proud of the success rate of more than 90%. Long term success rate of more than 90%, or even higher. When an implant is not successful, it is necessary to remove the implant, indicating that the implant is not easy to achieve osseointegration. At this point, your oral surgeon will give you the following advice: to implant a new implant, but the healing time is longer, and may need to repair bone graft.

The first patient in the world has been in use since 1965, more than 40 years. Second patients were close to the last 50 years, and were still in use because they had not died and were still in use. In general, the effect of the implant depends mainly on the level of technology and the quality of the implant, with the extension of the use of time, the patient how to use, maintain and clean, increasingly important.

9, how long does it take to heal?

Healing time varies from person to person. There was a close correlation between the quality of the jaw and the additional surgery. Overall, however, the healing of the implant requires 2-4 months (without the premise of an additional bite force). Recent studies have shown that a good combination of bone and titanium promotes healing, and that all implant manufacturers shorten the healing time (which is not up to standard). In recent years, studies have confirmed that in the same period or in the short term after implantation of dental implants can be loaded with dentures. Although this is common now, the healing time of 2-4 months is still the time needed to be repaired.

10, how to carry out routine maintenance?

Oral hygiene

Daily maintenance of implant is the key to normal oral function. Although it is not as easy as natural teeth, but it is prone to gum inflammation around the implant. Infection and bone loss. The infection and inflammation around the natural tooth is called periodontal disease. Similarly, inflammation around the implant is called peri implant inflammation. Your dentist will use appropriate methods to keep the body clean and healthy. But their regular brushing and flossing is essential. Dentists or dental health care providers will provide other tools to keep the surrounding clean and healthy.

Oral examination

New dentures should be regularly checked to ensure the health of the surrounding gums and bones. Therefore, we need to take X-ray to evaluate the bone mass around the implant. The attachment of the denture and implant should also be checked to ensure functional stability.

Loosening of the screws between dentures and implants is rare. If you need to remove loose denture, clean up and re placed new screws. If the denture is bonded to the implant, the same can be loosened. If you remove loose denture, clean, can ensure the retention and re adhesion after re. Although the probability of these cases is very low, but once it appears, it will be a very tricky thing, it is not to be ignored. There will be more problems if the denture is not attached to the implant without treatment.

11, the common cause of tooth loss

If there is one or more missing teeth, dental implants are an excellent choice.

Causes of tooth loss in many aspects of congenital missing teeth, trauma, oral disease (caries and periodontal disease) and some mechanical damage.

Congenital missing teeth

Congenital missing tooth or teeth is rare. In most cases is retained deciduous teeth, but not a permanent adorable. Missing teeth usually occur in the teeth fall out. If you find no following permanent teeth, so teeth usually keep to exercise the normal function, if appear teeth root resorption or other diseases, should be removed.

In the molar region of implants, oral cavity doctor will confirm the planting area has no permanent tooth germ. The most common areas of missing teeth were maxillary lateral incisors and premolars.

And trauma

Trauma caused by lack of teeth is multifaceted. Because children are caused by falls face hit the ground lead to tooth impact. Children affected by trauma will appear in months or years. For root fracture, unless secondary infection, usually do not have obvious symptoms. Sometimes the teeth after trauma, the treatment is very perfect, but still inevitably appear after the root absorption. This is due to the body's defense response to its own inflammation leading to autophagy in root surface cells. Trauma can also cause partial resorption of bone in the edentulous area.

Severe injury caused by trauma, which may affect the morphology of dentition. In addition to tooth loss caused by jaw defects, trauma, another major factor. Surgical removal of an oral cavity or a mass in the jaw may result in secondary defects such as blunt trauma or ballistic injury. This defect is often associated with a reduction in bone mass or interruption of bone continuity, requiring surgical repair of the missing bone and repair of the denture.

Oral diseases

The most common causes of tooth loss is gingivitis or periodontal disease. It is usually associated with a secondary infection of the root of the gum and bone that results in bone loss. Teeth often fail to function properly. Some even loose will fall off. Dental caries often results in the loss of dental function. The teeth are usually removed to prevent infection from affecting the jaw.

If the tooth coronal fracture or root fracture and cannot be retained when needed removal may be due to bruxism or clenching or something caused by mechanical damage resulting from the bite force and tooth loss function.

12, the cultivation of some problems

Single tooth missing fixed bridge can be made or implant

The fixed bridge restoration is very convenient to grind except adjacent two teeth gap or more teeth to produce denture. The repair of fixed bridge excessive force and regular flossing is difficult. If the abutment tooth is decayed or periodontal, removal of the fixed bridge. In order to prevent the occurrence of this kind of thing, it is usually necessary to kill the dental pulp nerve before removing the adjacent teeth, and root canal therapy to eliminate the infection of the pulp nerve.

Implant restoration is to avoid the adjacent teeth and replace the missing teeth

The simulation of the implant is higher, and can be portable floss. When the implant implant is stable and can bear the bite force, you can repair the healing abutments and crowns. The impression can record the base station form, then the crown can finish retention or screw retention. Although the implant is not easy to occur, but if the oral hygiene is not clean, it will cause some complications. Therefore, patients with implant repair should be regularly reviewed to ensure long-term stability of the implant.

Implants are generally made of titanium implants, implant into the mandible by surgical methods, and get the solid support of bone tissue, through the special devices and methods to support the upper dental restoration. Dental implants can be used to repair the teeth with the similar function, structure and aesthetic effect, which has become the first choice for more and more patients.

There are five procedures for dental implants:

1 preoperative examination, the development of treatment plans, the necessary periodontal treatment, and health education. Preoperative examination mainly includes oral examination and imaging examination, local beat dental CT clear bone condition. Perfect preparation, healthy periodontal condition and good living habits are essential to ensure the success of dental implants and long-term use.

2: the implant surgery is through the operation of the titanium implant alveolar bone, to become the new root, the next step to facilitate a. However, if the alveolar bone mass is insufficient, the need for bone grafting. The general process of implant surgery is relatively simple, does not cause pain, do not have to worry about.

3 connect the implant superstructure: through some special instruments to implant and bone healing has been connected to the mouth, for a.

4: artificial denture wearing crowns, or for denture repair.

Maintenance and regular visits for 5 dental implants.

Cost: hospitals and local governments in accordance with the level of local economy and level, the difference between the larger costs. Our hospital according to whether need bone graft cost differences, generally each tooth is about 20 thousand, the low cost without bone graft, bone graft need according to the difficulty will be higher.
