Description
Technical Field
The utility model relates to the technical field of tooth correcting appliances, in particular to a mandibular molar advancing device.
Background
An's II errors
Is a common mistake>
Deformities, which require neutral relationships to be achieved by correcting the molar distantly relationship. But in certain special class II errors>
In middle, correction of molar class II relationships remains a difficult problem: for patients with bone type II complicated with crowding of anterior teeth or lip compensation, the upper and lower first premolar teeth are usually required to be pulled out to relieve crowding or remove compensation, and the correction of the subsequent molar relationship is complicated; if it is bone II, open->
Patients with temporomandibular joint disorders who experience mandibular traction can cause joint discomfort. Currently, clinically common methods for improving the molar class II relationship include: inter-jaw class II elastic traction, forsus appliances, and the like. However, it has been reported in the literature that inter-jaw class II traction causes clockwise rotation of the occlusal plane, aggravates mandibular recession, is not conducive to class II facial correction, and the efficacy depends on patient compliance. The forsus appliance may cause depression of the maxillary first molar and undesirable irritation of the soft intraoral tissue. Therefore, it can be seen that the conventional methods for correcting the remote relationship of molars have limitations.
To correct the molar mesial relationship, the bilateral mandibular molars can be moved mesially to achieve a good molar neutral relationship. If the mandibular molar is moved mesially, the anterior anchorage needs to be strengthened, and if the mandibular molar is moved anteriorly as a dental anchorage, adduction of the anterior teeth and poor mesial movement of the molar may occur, so that a more stable anchorage is sought to reduce the influence on the anterior teeth. Current miniscrew has become a recognized reliable method of providing temporary anchorage, which is easier to place and remove, smaller, and more cost effective than traditional anchorage methods. Several researchers have used micro-implants as stable anchorage substitutes for mesial displacement of molars. We can therefore consider correcting the type II relationship with implant anchorage advancing mandibular molar.
Currently, the common method for correcting molar II relationship by using a planting nail clinically comprises the following steps: 2 planting nails are respectively implanted between the lower jaw back part or the lower jaw side incisor and the cuspid to draw the molar to move in the middle. Wu JC et al, however, believe that implanting implant mesial moving molars on both sides of the posterior mandible, respectively, may cause rotation of the occlusal plane and prolong the treatment time. If the implant is implanted between the lateral mandibular incisors and the cuspids on both sides, the soft tissue of the mucosa may be compressed during the mesial movement of the elastically drawn mandibular molars due to the anatomical morphological characteristics of the mandible, resulting in injury and inflammation of the mucosa. Therefore, a more ideal position for implanting the implant to strengthen the anterior anchorage is required. The literature suggests that micro-implants in the anterior mandibular region may be used clinically for the impaction of lower incisors, mandibular fixation and molar advancement. Total bone thickness (OBT) and Cortical Bone Thickness (CBT) were measured in the mandibular union region of CBCT in 32 adolescent and adult patients, zhang shizhen et al. The results show that CBT and OBT are the largest in position between the two lower central incisors, and that the quality of the alveolar bone on the labial side of the roots of the mandibular incisors is sufficient to accommodate the mini-implant without the risk of root damage. The recommended optimal implant site is 6-10mm from the top of the CEJ between the two lower central incisors. Therefore, the lower anterior interdental is a more ideal implant implantation site, but if the molar is pulled by the elasticity of the implant directly in the anterior area, the gingiva is compressed, and how to reasonably utilize the anchorage of the implant is a problem to be considered. It is therefore desirable to more rationally design a device that can utilize the anterior mandibular area implant anchorage to move the bilateral mandibular molars medially and correct the molar distancing relationship.
