Can difficult tooth extraction be corrected without implant nails?
Half a year ago, at the 20th National Orthodontics Academic Conference, Dr. Shu Guang, chief orthodontist in Peking University, lecturer in Invisalign Asia-Pacific region and orthodontist in Hesheng, gave a lecture in Invisalign on so-called anchorage in tooth extraction treatment, giving a deep explanation on anchorage relationship, anchorage design, anchorage control and management in tooth extraction treatment. It also explains a difficult case of tooth extraction without using implant to control tooth movement.
In this case, the maxillary anterior teeth need to be repaired more than the mandible during the treatment. A large number of posterior teeth move forward is a very difficult technical activity. Director Shu Guang showed orthodontists efficient orthodontic treatment through accurate diagnosis, scientific and reasonable fine design and strict follow-up monitoring.
For such a difficult case, the implant anchorage was not used, and the correction was completed only by the strength of invisible braces for two years, which made the patient experience a more comfortable and relaxed correction experience and won unanimous praise from professional doctors in the industry, calling it a "groundbreaking" case.
Through clinical practice, Dr. Shu Guang demonstrated that only by using the flexibility of the appliance can moderate anchorage be controlled to a great extent, and also showed his pursuit of "making full use of the performance of the appliance and striving to achieve the correction goal". This can not only reduce the use of implant nails, improve the comfort of correction, but also save treatment costs.
Generally speaking, this kind of tooth extraction correction needs some clinical auxiliary operations to achieve the therapeutic purpose more easily. In this case, Director Shu Guang did not use intermaxillary traction, implant anchorage or segmental arch, but only achieved the purpose of correction through reasonable and scientific scheme design and strong anchorage control, and the patient completed the correction in a more relaxed and comfortable feeling.
If you can't escape the use of implant nails in clinic, don't be afraid and worried. Here is a brief introduction to implant nails.
What is an implant nail? What is the function of planting nails?
Implant nail, also known as anchorage nail, is a tool to assist tooth movement. Implant nails are implanted in bone and bone is used as anchorage, which can meet the demand of anchorage in orthodontic treatment.
What is Anchorage? ? In the process of orthodontic treatment, any force applied to the teeth to move the teeth will inevitably produce a force in the opposite direction and the same size, and the situation of supporting this movement to correct the reaction force generated by the teeth is called "anchorage". Simply put, anchorage is to resist unnecessary tooth movement. However, the implant implanted in the bone will not move because of stress while pulling the teeth to move, so it is called strong anchorage.
02? Do I need to implant my nails to correct my teeth?
Implanting nails is just a form of anchoring? There are many common anchorage devices. One or a group of teeth are often used as anchorage devices in orthodontics to meet the needs of orthodontics through "tooth extraction".
Whether it is necessary to make implant nails to correct teeth depends on the severity of malocclusion. Generally, serious problems such as buck teeth, open jaw, deep overbite jaw, reverse jaw, gingival smile, etc. are easier to be corrected with implant nails.
Special circumstances need to see the appliance selection and correction scheme? For example, if you don't want to extract teeth, invisible braces generally doesn't need implants, because invisible braces is good at "pushing" the force; If the bracket is selected for orthodontic treatment, the soft wire should be aligned in the early stage, and the step of pushing the molar away should be started when the steel wire is changed for traction in the later stage. At the same time, implant anchorage should be used to assist the whole dentition to be removed at the same time. Compared with invisible correction, it increases the probability of using implant nails.
03. Does it hurt to hit the planting nail?
Bone nails are implanted in the jaw, so it is even more painful for some friends to hear that they are going to implant bone nails. In fact, compared with tooth extraction, nail implantation is a piece of cake. First of all, the planting nail is very small, with a length of only 7~9mm and a diameter of about1.5 mm.
Secondly, there are not many painful nerve endings distributed in the alveolar bone, and anesthetic will be used before the implant is implanted in the jaw, so the process of implanting the implant is very easy, so don't worry; Most people have no obvious pain after anesthesia metabolism, and a few people will have discomfort similar to that when they just wore braces. Generally, the pain will go away within one day.
After planting the nail, use mouthwash and oral anti-inflammatory drugs according to the doctor's advice, and pay attention to cleaning the area around the nail with interdental brush.
04? Will there be a hole when the implant nail is taken out?
No holes will be left, the oral intima has strong self-healing ability, and it can heal within two weeks without leaving traces, and the alveolar bone will slowly complete healing and reconstruction within three months.
However, some friends also asked doctors to make implant nails, so as to close the gap between teeth faster and speed up the correction process. In fact, it still depends on whether the correction plan and personal situation are necessary. In addition, the time and effect of correction are influenced by many factors, such as the doctor's control over the performance of the appliance, the choice of accessories, the use of anchorage, the movement of the target position in the direction of the root of the tongue, the tooth torque, the root-crown ratio, the number of moving steps and the interaction of various factors.
As far as anchorage is concerned, only correct anchorage design and good anchorage control can achieve efficient correction.
Whether to use implants depends on personal situation and doctor's scheme design. Before the implant is implanted into the alveolar bone, the doctor will analyze the implant position according to the tooth section and operate it in a sterile environment, which is very safe and secure. You can usually brush around the implant with an interdental brush to avoid inflammation around it. More personalized dental questions are welcome to consult.
