Under what circumstances can dental implants be done?

Q: Under what circumstances can I have a dental implant?

In the past, the limitations of implant denture restoration were relatively large. With the continuous development of implant denture technology, its superiority and its success in long-term clinical practice have continuously broadened the indications for implant denture. In the early days, implant dentures were mainly used for edentulous patients, and now any tooth loss can be repaired with implants. At the same time, it is suitable for those who have difficulties in denture retention due to various reasons, or those who cannot be repaired by traditional methods due to dysfunction caused by psychological factors.

In addition to patients with normal oral conditions who can choose to have implant dentures, implant dentures can also be used in the following situations: the ①Insufficient alveolar bone volume can be solved by bone grafting. ② For the problems of maxillary sinus and mandibular canal, implantation can be guided by X-ray film and CT, and spiral CT can guide the direction more accurately. Choose the appropriate implant length and accurate implantation angle. ③ implant immediately after tooth extraction. ④ For patients with insufficient economic conditions, the method of overdenture restoration can be used. ⑤ Defects of the jaw, facial tissue and organs can also be repaired by implantation. However, artificial dental implant restoration still has a certain scope of application. Oral examination, panoramic X-ray film and blood routine examination should be performed by a professional physician before determining whether the patient is suitable for surgery.

What are the advantages of dental implants?

Dental implants have many advantages over traditional dentures. Its shape is realistic and beautiful; it has good stability, and its chewing function is much better than that of traditional movable dentures; it does not need to grind the good teeth next to the missing teeth, which protects the patient's healthy teeth to the greatest extent; it is small in size and minimizes the impact of dentures on pronunciation. impact; comfortable and hygienic; neither afraid of cold nor acid; easy to use. Whether the tooth decay is too deep, or the tooth needs to be extracted due to trauma, dental implants are the most comfortable and beautiful choice at present, so that you no longer need to wear dentures that "look fake, and wear fake". the The upstart of dental implants: If there are teeth that need to be extracted, the conventional repair method is to extract the teeth first, and start to install the teeth after the extraction socket heals 2 to 3 months later. If it is the front teeth, it goes without saying that they are ugly during this period. Even if you make a plastic temporary denture, it will not look good, and the foreign body sensation is obvious, and it is very uncomfortable to wear.

The next step is to choose between removable or fixed dentures. Removable dentures have to be removed and worn every day, which is really troublesome! It is uncomfortable to wear, and the clasp (metal hook) will be exposed, which affects the appearance. Fixed dentures, while much more aesthetically pleasing and comfortable, require grinding of the teeth on either side of the missing tooth. the Dental implants are as beautiful and comfortable as fixed dentures, and at the same time do not need to grind adjacent healthy teeth, so it is a good choice. Sometimes it is also possible to perform implants at the same time as tooth extraction, so that there is no time for missing teeth and basically does not affect social activities. Whether it is suitable for immediate planting depends on the specific situation.

How long do implants last?

Depending on the clinical situation, the success rate of implant treatment is about 90%. It is also possible to keep it for life. Implant dentures can be considered to a certain extent like natural teeth and function in a similar way. Excessive force can lead to denture damage and implant loosening, and poor oral hygiene risks infection of the peri-implant tissue. Regular oral examinations after surgery are mandatory. In addition, there are a large number of implant systems now, and choosing a reliable implant system is the key.

How long does implant treatment take?

Implant treatment can generally be divided into three stages: preoperative preparation, implant placement surgery and implant denture restoration. In the preparation stage before implantation treatment, systematic specialist examinations should be carried out, such as: X-ray films, blood tests, etc. In addition, the formulation of implant treatment plan and series of preparations are also carried out. The time will take days. Implant surgery is usually performed under local anesthesia. The operation usually takes 1 to several hours. On the day of the operation, the patient should eat normally before the operation, and eat soft food, liquid, etc. after the operation. After the operation, you should take medicine according to the doctor's requirements, return to the clinic, and pay attention to keeping your mouth clean, and take out the stitches in 7-10 days. Repairs are usually performed three to six months after surgery. First, the second-stage surgery is required, followed by model taking, denture production, and dental work. Treatment usually takes 2-3 weeks.

What problems might arise with dental implants?

In rare cases, poor healing between the implant and the bone may occur, causing the implant to loosen and fall out. If an infection occurs in the implant area, it may spread to other parts such as the maxillary sinus. Nerve damage is possible when implants are placed behind the mandible. Different degrees of pain, edema or bruising may occur after implantation.

What is Dental Implant Success Criteria?

1. Gingivitis is under control and there are no implant-related infections.

2. No damage to the supporting tissues of adjacent teeth.

3. The implant has no clinical mobility under the condition of supporting and retaining the denture function. Good function. The chewing efficiency is over 70%.

4. The appearance is beautiful, and there is almost no difference in color from the adjacent teeth.

5. No persistent and/or irreversible mandibular canal, maxillary sinus, nasal floor tissue damage, pain, numbness, paresthesia and other symptoms after implantation, and feel good about themselves.

6. Bone resorption in the vertical direction does not exceed 1/3 of the length of the part implanted in the bone when the implant operation is completed (displayed by X-ray films using standard projection methods). The transverse bone resorption does not exceed 1/3, and the implant does not loosen.

7. In radiological examination, there is no radiolucent area at the bone interface around the implant. Failure to meet any of the above criteria will not be considered a success.
