How to treat 9-year-old boy's congenital absence of permanent tooth germ

summary

Congenital missing teeth is a common dental deformity, but its molecular biological mechanism is still unclear. It occurs in the early stage of tooth development, that is, the formation of tooth buds. There are different reasons for this: 1. The development of embryonic dental plate is affected by physical barrier or fracture. 2. Limited space, resulting in pressure, so that the tooth germ can not get the minimum nutrition and degradation, especially the third molar. 3. It results in functional defect of epithelial tissue and failure of mesenchymal induction. At present, many studies have proved that the occurrence of congenital missing teeth is related to genetic factors. How to do with congenital tooth loss? Let's talk about it.

How to treat 9-year-old boy's congenital absence of permanent tooth germ

First, when the number of missing teeth is small, it has little effect on masticatory function, dentition morphology and aesthetics, and generally does not need special treatment.

Second, when the number of missing teeth is large, it not only affects the chewing function, but also affects the appearance of patients, causing damage to the physiological and psychological of patients. In order to restore masticatory function and promote the development of maxillofacial bones and muscles, the removable denture should be carried out in time. However, it should be noted that the denture must be replaced continuously with the growth of children's teeth and jaw. Generally, the denture should be replaced once a year to avoid hindering the children's need for removable denture, so as to help restore masticatory function and promote the growth and development of maxillofacial region.

Third: children with congenital missing teeth can not get the corresponding treatment, with the growth of age, the remaining deciduous teeth gradually loose and fall off, it is generally recommended to wear dentures as early as possible in childhood to restore the function of missing teeth, so that the edentulous area of the jaw by chewing stimulation and promote the development of the jaw, while avoiding the compensatory hyperfunction of soft tissue, to create conditions for later repair. The patients with congenital multiple tooth loss usually have poor vertical and horizontal jaw development, which brings great difficulties to the repair work. If they can carry out mandibular implant denture repair in their childhood, regularly review and timely replace dentures suitable for growth and development, the maxilla and mandible will be stimulated to some extent, which will improve the patient's face shape, the development of maxilla and mandible and the development of adults Repair should play a positive role. However, implant in childhood may cause relative implant subsidence, so implant repair should be cautious.

matters needing attention

For the patients with congenital multiple tooth loss, the common restoration methods include fixed denture, removable denture and implant supported denture; If necessary, orthodontic treatment and orthognathic surgery must be combined to achieve better results. However, patients with mandibular permanent dentition loss have jaw hypoplasia, and alveolar bone in edentulous area is severely dysplasia, which is blade like, almost level with vestibular groove, and difficult to retain. Traditional removable denture is difficult to achieve ideal results.
