For many orthodontic patients, hearing that bone nails need to be done may feel worried and frightened, and even have the psychology of "talking about bone nail discoloration". However, is it necessary to have nails in orthodontics? What does a bone nail do? Today we will answer these questions so that you can have a clearer understanding of the anchorage device in orthodontics.
Whether it is traditional fixed orthodontic or orthodontic, the basic principle is to apply force to the tooth, so that the alveolar bone is remodeled by the force, so as to realize the movement of the tooth. However, the action of force is reciprocal, and the force exerted on the tooth produces a reaction force of the same magnitude and in opposite directions.
In the process of applying force, in order to counteract the reaction force, it is usually necessary to add many attachments to the archwire as a fulcrum. These accessories include towing hooks, lingual side buckles, concealment buckles, Zhengya hooks, etc., through which the fulcrum is increased for better orthodontic treatment.
Compared with traditional fixed orthodontic treatment, ** orthodontic treatment is better than the whole front tooth as a whole when the posterior teeth are moved, and the back tooth as a whole when the front teeth are moved. This reduces the use of metal attachments, reduces patient discomfort, and makes oral cleaning easier.
However, for some complex cases, relying solely on the overall resistance provided by the anterior or posterior teeth may not be sufficient. At this time, the anchorage nail came into being as an anchorage device. Anchorage nails are implanted in the alveolar bone and can provide greater resistance than other devices, thereby speeding up the movement of the tooth and improving the efficiency of orthodontic treatment.
The process of anchorage nail implantation is relatively less invasive and rapid. Before the operation, the dentist will determine the root and alveolar bone of the tooth based on the patient's CBCT image, and determine the implant site of the anchorage nail. Local anesthesia is given during the procedure to ensure that the patient feels the best during the procedure. After surgery, the mucosal surface is basically healed in about a week, and the corresponding traction can be applied after two weeks on the anchorage nail.
In general, the need for nails in orthodontics is not absolute, but depends on the specific situation of the patient. As a highly efficient anchorage device, anchorage nails play an active role in some complex cases. Choosing a formal medical institution and following the advice of professional physicians can better achieve the effect of orthodontics and protect the oral health of patients.
