Why do dental implants need bone grafting?
Dental implant is a kind of treatment method to implant teeth in oral cavity by artificial method, which can effectively solve the problem of missing teeth in oral cavity. Bone grafting is a common technique in dental implant surgery, which can increase the bone mass in the implant area and improve the success rate and stability of dental implant. The following are specific reasons:

1. Bone resorption caused by tooth loss: Long-term tooth loss will cause bone resorption around adjacent teeth, resulting in insufficient bone mass to support dental implants.

2. Jaw loss or atrophy: Some patients may have jaw loss or atrophy due to jaw deformity, jaw dysplasia or trauma. This kind of jaw cannot support dental implants and needs bone grafting.

3. Improve the growth environment of teeth: Bone grafting can improve the bone density and bone height in the implant area, and make the growth environment of dental implants more stable and healthy.

Therefore, in dental implant surgery, doctors may implant artificial or autologous bone materials into the missing tooth area as the basic support for dental implant. After successful bone grafting, dental implants can be better stabilized in the mouth, achieving better aesthetic and functional effects.
