Implant Supported Over Dentures
The jaws are composed of two types of bone called basal bone and alveolar bone. Most of the major vessels and nerves are in the basal bone and the teeth are housed in the alveolar bone. When teeth are lost, the alveolar bone no longer has a function and resorbs over time. If all the teeth are lost as is the case in full denture wearers, there is considerable bone loss over time. This is more noticeable on the lower jaw as there is less bone here to start.
This brevity of bone can make wearing dentures, especially lower dentures, very difficult due to movement. It can also be painful as the lower denture will eventually lie on basal bone and therefore on nerves and blood vessels housed in this bone.
If dental implants are placed in the jaw, they can support an implant assisted over denture. Implants are placed that have snap-like anchors. These snap into corresponding anchors on the denture giving security and confidence to the patient. The denture can be removed by the patient.
This relatively simple technique can truly revolutionise people’s lives as it allows more comfortable nourishment and confidence when speaking.
