The so-called Minimally Invasive Dental Implant (MIDDI) is the application of minimally invasive technology to the field of dental implants, using a special surgical method and technique (Graftless solution) to complete the implantation process based on traditional dental implants. “The implant is inserted into the mouth using a tiny incision (3-4 mm), which eliminates the need for traditional dental implant incision, suturing and suture removal, minimizes trauma, greatly reduces swelling and bleeding, significantly shortens the time required for the implantation process (only 15-30 minutes), and reduces the risk of infection. Swelling is the most widely used implant method internationally. The advantages of minimally invasive dental implants: 1, good retention: no traditional retaining rings or braces are used, the artificial tooth roots are closely integrated with the alveolar bone and rooted in the mouth like real teeth, with strong retention and stability. 2.Aesthetic: The crown can be made according to the shape of the patient’s face and the shape and color of the other teeth to achieve the best overall coordination and aesthetic effect. 3.Strong function: It can restore the function of teeth well and chewing function is much better than other traditional dentures. 4, no grinding: rely on their own artificial tooth root for restoration, without grinding the next healthy teeth, there is no harm to the teeth. If it doesn’t work, you can take it out and wait for the bone to heal before doing the implant, or use other restorative methods instead. 5.Simple operation: local anesthesia is used, which is less traumatic and can be eaten after the operation, almost painless. The general implant placement can be completed in a few minutes to a few hours. Due to the use of biomaterials with excellent compatibility with the human body, dental implants do not have any adverse side effects on the human body. If the osseointegration of the dental implant fails, it is also a dental implant. 6. Comfortable and convenient: without using the necessary abutments and movable dentures, there is no foreign body sensation, which is very comfortable and convenient, and is conducive to maintaining the cleanliness and hygiene of the mouth. Suitable for the crowd: Minimally invasive dental implants are not suitable for everyone. For example, some patients with periodontal disease have only a little bit of keratinized gums left because of the disease, which is not suitable for minimally invasive dental implant surgery, and unless the bone foundation is very wide, it is not easy to position the implant by drilling directly into the gums, and the difficulty of the surgery is also very high. Generally speaking, the suitability of a patient for minimally invasive dental implants must be carefully evaluated by a professional dentist. The most important thing is whether the bone and gums can be repaired quickly when the flesh is opened and the surrounding environment of the implant is handled well. Indications: 1. Adults who are in good general condition, physically and mentally healthy, and whose bones and teeth have already developed. 2. At least 6 months after surgery and trauma to the jaw bone and alveolar bone, and at least 3 months after tooth extraction, the bone defect has been recovered and the bone form and quality of the implant bed are good. 3. The oral soft tissues are free of obvious inflammation and lesions. 4.The patient himself has a clear request and the economic condition permits. 5. The professional physician conducts oral examination, takes panoramic X-ray and does routine blood examination, if there are bleeding disorders, hypertension, heart disease, diabetes and other systemic diseases, the patient can only receive dental implant surgery after the treatment of the disease is stabilized. Complications of minimally invasive dental implants: 1. Perforation: During the healing phase, the gingival tissue covering the implant is perforated, which may be due to excessive tension of the flap during suturing, poor suturing; or residual sutures stimulating the proliferation of granulation tissue; or the pressure of the restoration, producing a decubitus ulcer of the gums. 2, gingivitis: is due to poor oral hygiene, plaque stimulation, when the gingival tissue is not yet significantly proliferated. 3, hyperplastic gingivitis: due to the gingival tissue covering or tightly attached to the connection between the implant abutment and the bridge, resulting in poor local hygiene, resulting in hyperplastic inflammation of the gingival tissue. Proliferative gingivitis is usually treated by surgical methods. 4. Fistula formation: The fistula on the mucosa is related to the inflammation around the abutment or implant. It occurs mostly in cases where the gingival tissue covers the abutment and bridge union; it can be treated by surgical scraping. 5. Progressive marginal bone resorption: peri-implant bone resorption caused by local inflammation or implant overload and central bolt fracture. Cleansing to remove the plaque, for the etiology of treatment. 6, implant loosening, fracture. 7, other injuries: mainly poorly designed surgical preparation caused by implant penetration into the maxillary sinus, nasal floor, inferior alveolar nerve or adjacent teeth injury, and even mandibular fracture. Pre-operative preparation: 1. Pre-operative routine examination: check the site of missing teeth, gap size, width of alveolar bone, condition of alveolar ridge, condition of mucosal tissue, and choose whether to plant and plant several implants according to their size, width and height. 2. Radiological examination: mainly to understand the density and quantity of alveolar bone and the presence of disease. Dental radiographs can clearly understand the density of alveolar bone and partly understand the amount of alveolar bone. As well as the periodontal tissue, dental tissue and root tip of adjacent teeth. Maxillary surface tomographic panoramic film can understand the height of alveolar ridge, nasal floor, maxillary sinus height, inferior alveolar nerve situation, and the position of chin foramen. Spiral CT, which can accurately understand the alveolar bone height, width, accurate positioning and preoperative simulation of surgery. For implantation in the posterior region, spiral CT is necessary because of the height of the maxillary sinus and the inferior alveolar nerve. 3. Pre-implant design: Before the implant surgery, the first step is to take photos to take models and other data collection work to determine the type of restoration, the implant system, the number, location, direction and length of the implants, and then make a template for the implant surgery so that the surgery can be performed accurately and smoothly. 4. Before the operation, some antibiotics should be given so that they can better inhibit bacteria. Post-operative attention: 1. Antibiotics are routinely used after surgery. For simple implant surgery (small number of implants, short surgery time and good recovery of patient’s body), oral antibiotics are given after surgery, and complex implant surgery requires intravenous application of antibiotics to prevent infection. 2. Don’t brush your teeth and use water within 24 hours after surgery, because over-frequent rinsing may lead to tooth bleeding, but you can rinse your mouth with mouthwash after meals to prevent residual food residue in the mouth, you can eat and drink moderately 2 hours after surgery, and food should not be too cold and too hot. 3.Patients generally have only slight hidden pain or discomfort after surgery, no need to take painkillers, but if patients are sensitive or feel local pain, you can add painkillers on the day after surgery, the general normal situation is that 24 hours after surgery, patients will no longer have continuous pain sensation. 4, due to the different physical and surgical procedures of patients, there may be different degrees of surgical reactions, some patients have light reactions or no uncomfortable reactions, some will have local edema and ecchymosis, which usually lasts about 3-5 days. 5.The stitches will be removed in 7-10 days after the normal operation, and timely removal of stitches can prevent local infection.
