Dental implant is an artificial implant (artificial root) surgically implanted in the alveolar bone, and after it is integrated with the alveolar bone, an artificial crown is installed on the implant root to restore the maximum function of healthy teeth such as chewing, pronunciation and aesthetics. The process is not particularly complicated, but in order to ensure the reliability of the surgical effect and the safety of the surgical procedure, we hope that you will learn more about the general process and basic knowledge of the surgery, as well as some details that should be noted before and after the surgery to ensure the success rate of dental implants and fully reflect the effect of dental implants. Pre-operative preparation 1. A good oral environment is the guarantee of successful implantation Oral examination, especially periodontal examination and treatment is very important. Patients with periodontitis have a large number of bacteria on their teeth, and these bacteria may enter the wound during implant surgery, greatly increasing the chance of implant infection and leading to implant failure. In addition, there are other conditions that may bring about oral or alveolar bone infections, such as severe caries, stumpy root crowns, poorly fabricated fixed dentures, etc. All these conditions need to be treated before surgery. 2. Bone quality assessment Since the implant is to be buried in the alveolar bone, the bone quantity and quality of the alveolar bone are inevitably related to the success or failure of the implant. Therefore, bone quality assessment should be performed before implantation. Usually, the longer the tooth is missing, the more severe the bone loss will be. Therefore, implantation should be done as early as possible when teeth are missing. In addition, some systemic diseases, such as diabetes and osteoporosis, can affect bone quality. Therefore, these patients should inform the doctor before surgery to assess the risk of the procedure. 3. Prepare a transitional denture Most patients need to use temporary dentures to help get through the implant and bone healing time. If temporary teeth can be made before surgery, the patient can wear them immediately after surgery and they will not affect their normal life. Surgical procedure Implant surgery is like putting a nail in a banana. First, just like peeling the skin of the banana to expose the flesh, the surgeon has to cut the gum to expose the bone tissue, then position the implant on the alveolar bone and prepare the socket for the implant, and finally place the implant and suture the gum so that the implant will slowly heal to the bone under the gum. Usually, after three months of implant growth, a denture crown will be placed on the implant. Post-operative dental maintenance 1. Just after the crown is placed, you should follow the principle of gradual stress and eat something soft first. Because the bone of the implant is not stimulated by chewing for a long time, bone resorption is likely to occur when it is subjected to strong force at the beginning, after a period of exercise, this can be avoided. 2, should not chew too hard things. On the one hand, because there is no periodontal membrane pressure receptor around the artificial root, so the bone tissue around the implant is vulnerable to damage and resorption; on the other hand, the crown of the upper part of the dental implant is usually porcelain crown, too much force is easy to make the porcelain chipped, and it is not easy to repair after damage. 3, after the dental implant should pay more attention to the cleaning and maintenance of teeth. Although dental implant will not have caries, but if the oral hygiene is not good, it will suffer from periodontitis. Therefore, after the success of dental implant, you should brush your teeth twice a day and go to the hospital to clean your teeth regularly (every six months).
