The so-called minimally invasive, relative to the traditional surgery, in order to achieve the therapeutic purpose at the same time has the characteristics of fast recovery, small incision, less trauma, less pain. These four points must be available at the same time, and does not have a negative impact on the patient’s psychology. Because any surgery will cause a sense of fear on the patient’s spirit, as a doctor should show a humanistic care. There are many friends have a tooth extraction or watch the experience of tooth extraction, looking at the doctor holding a similar chisel, pliers, hammer tools, in the patient’s mouth, knocking, shocked the mind numbness, two ears buzzing, not like a doctor in the treatment, like craftsmen in the repair of the machine. It really gives a feeling of execution, and even the strongest people are afraid to break out in a sweat. Even the toughest person will break out in a sweat. People who have experienced this kind of tooth extraction will inevitably have a fear of it. Let’s compare minimally invasive tooth extraction with traditional tooth extraction to see the difference. The extraction technique is already considered a “minimally invasive” treatment compared to major surgery, but due to the special nature of the surgical site, it is actually no less frightening to the patient than other surgical procedures. Traditional extractions are performed using dental tines and Omei chisels, which inevitably use hammering to increase the gap, which is the main cause of discomfort for patients. In addition, extractions using traditional dental tines are performed using leverage, axle and wedge forces, with leverage being the main force used. The use of leverage force often results in the occurrence of gingival tearing and fracture of the alveolar bone. The use of minimally invasive extraction tools does not require the operation of hammering to increase the gap, and in the way of applying the force is mainly based on the axial force and wedge force, which avoids the corresponding adverse reactions by not using the lever force, so minimally invasive extraction is a revolutionary method of extracting teeth at this level. Minimally invasive tooth extraction system consists of: 1. minimally invasive concept 2. painless technology 3. minimally invasive equipment Minimally invasive concept: familiar with the anatomy of the dentition and periodontium, the design of the surgical program before the extraction of the tooth, taking into account the dislocation of the tooth and the surrounding hard and soft resistance, controlling the size and direction of the force, to avoid the surrounding tissues as well as the damage to the tooth. In short, we should consider how to use the smallest force, the smallest extraction trauma, the shortest time to remove the affected teeth according to the plan. Minimally invasive equipment: Including minimally invasive dental tines, fit extraction forceps, ultrasonic bone cutters, 45-degree contra-angle turbine handpieces, elongated dental impaction pins, periodontal membrane separators (self-initiated), and even maxillofacial surgical pneumatic bone cutters, bone files, and so on. The better and more precise the material of the instrument, the less damage it will cause. Painless technology: Currently, the mainstream painless technology adopts the painless injection instrument and “Bilan Ma” produced by French Bilan Company. Surface anesthetics are first applied at the injection point and then injected with a very fine special syringe, which is basically painless. Minimally invasive tooth extraction process: first, local tissue anesthesia with painless technology, under sterile conditions using imported, special dental drills, the teeth will be divided, and then minimally invasive tooth extraction instruments inserted into the periodontal membrane and the alveolar bone between the separation of the teeth can be effortlessly from the teeth from the sockets “raised”. The blade of the minimally invasive extraction instrument is very thin and sharp, which can quickly and accurately cut off the periodontium and protect the integrity of the alveolar bone, resulting in minimal surgical damage, less post-operative pain, and faster healing of the wound than after a traditional tooth extraction. In general, minimally invasive tooth extraction has the following advantages over traditional tooth extraction: 1. No chisel and hammer are used in the extraction surgery, which reduces the patient’s fear. 2. 2.The instruments used in the surgery are all fine instruments with accurate operation and stable pivot point, which can minimize the patient’s injury. 3. There is almost no pain during the operation. 4.Significantly reduce the complications of tooth extraction during and after surgery. 5. The chance of wound infection after surgery is greatly reduced, postoperative pain is lighter and wound healing is faster. With the progress and development of the society, patients will have higher and higher requirements for doctors. Minimally invasive medical technology is a clinical technology that realizes the most perfect diagnosis and treatment effect on diseases through the smallest damage to human body. Minimally invasive technology is an important contribution of medical science to human civilization in the 21st century. Minimally invasive dental treatment technology is an important part of minimally invasive medical technology. We hope that our colleagues will give more humanistic care to patients and promote minimally invasive tooth extraction technology to avoid causing more pain to patients.
