Dental implants have advantages that are unmatched by other methods of dental placement. Dental implants are usually performed 3 to 6 months after the tooth is extracted, which takes a long time. With immediate implants, dental implants are placed in the original location of the tooth root while the tooth is extracted, allowing the implant to heal simultaneously with the extraction wound. The immediate implantation saves 3 to 6 months of time, avoids the pain of the second-stage surgery, saves some of the surgical costs, and allows the implant to be placed more precisely according to the space and angle of the original root. The immediate implantation of single-rooted teeth is more effective, but the results of multi-rooted teeth are not yet very certain due to the special anatomical structure. What are the dangers of dental implants? 1, gingival hyperplasia This is a complication caused by the implant “root” penetrating the gingiva too little, or the “root” is not connected well with the bridge. It will cause poor local hygiene and long-term chronic inflammatory stimulation, and the final result is gingival hyperplasia. 2. Wound fracture occurs when the suture is too tight or too loose during the dental implant process. Especially if the dental implant is not cleaned properly and infection is induced, it is more likely to cause local wound cracking. The way to solve the hazard is to clean the wound in time and suture it again in order to avoid the implant exposure. 3, lower lip numbness The technique of dental implant is in place, it will not damage the nerve, because underneath the alveolar bone is the nerve, called the inferior alveolar nerve, if the implant is put to the back, it will destroy that nerve, so in order to protect the nerve, it will be planted in front of the nerve. However, if the dentist damages the chin nerve during intraoperative stripping or directly traumatizes the inferior alveolar nerve during implant placement, then the patient will experience numbness of the lower lip. Damage to the chin nerve is mostly recoverable, but if the lower alveolar nerve is damaged, the implant should be removed and repositioned to avoid the nerve. 4. Infection If the patient does not choose a regular hospital for the operation of dental implants, then there may be the danger of infection. This is mostly due to the lack of sterilization or contamination of surgical instruments during the surgery. 5. Bleeding Dental implants are a minimally invasive procedure and there should be no bleeding after the implantation. Why would dental implants cause “bleeding”? This is due to the poor technique of dental implantation, because dental implants still have some damage to the periodontal tissues. If the dentist does a lot of damage to the mucoperiosteal stripping or extensive submucosal stripping, especially if the postoperative pressure is poor, submucosal or subcutaneous bleeding is likely to occur. There is also a case of bleeding from dental implants when the implant penetrates the lower edge of the jaw during the first-stage surgical implantation of the “nail”, which can also cause subchin bruising. The local bruising is usually absorbed after a few days and can be applied with cold compresses in the early postoperative period and hot compresses in the late postoperative period. However, if the patient receiving the dental implant has a tendency to bleed due to systemic factors, it should be treated symptomatically. How to avoid the hazards of dental implants? 1, should be the correct choice of hospital and specialist for treatment, first of all, to choose a formal, technically strong hospital; to carry out the artificial dental implant surgery physician must go through formal training. 2, should learn from the doctor about the knowledge and precautions of dental implants, clear dental implants for their own specific loss of teeth when the effect can be obtained, and good cooperation with the doctor. 3. You should ask the doctor whether the dental implant you are using is in accordance with international standards or licensed by the national legal authorities. In China, in addition to the production license from the State Administration of Medicine, regular dental implants must also be approved for clinical use by the Ministry of Health. It is important for patients to know the dental implant products they are using in order to protect their legal rights and to prevent a few doctors from violating the regulations and losing their medical ethics by using counterfeit and shoddy products to cause harm to patients.
