Implant Supported Fixed Dentures
Implant supported fixed dentures are wonderful alternatives for conventional dentures which create discomfort to patients. A full-arch of prosthetic replacement is supported by a few dental implants which are integrated with the jaw bone. Titanium implants are most commonly used for this purpose. There are retaining screws which help the dentures stay in place. These types of dentures are very effective when compared to their removable conventional counterparts.
Over dentures are prosthodontic replacements which are supported by dental implants. There are several ways in which dental implants can support teeth. Both partials and dentures can be supported by artificial teeth roots. This type of restoration supports biting and chewing function to a great extent. Patients feel very comfortable when living with over dentures. Removable over dentures have bars which are fixed over dental implants. The custom-made over denture is then fit over the bar. This over denture can be removed whenever necessary. Starting from two to as many as 5 or more dental implants can be used to support over dentures in an arch.
Bone grafting is a process which is essential when there is insufficient bone to hold the implant. If a lost tooth is not replaced in time the bone which supports the tooth starts to shrink. Dental implants cannot be inserted in such bone which does not have sufficient volume. Different bone grafting techniques can be followed to augment the bone. The complexity of the procedure and the time required for healing depends on the amount of bone loss. When there is more bone loss the dentist may use blocks of bone in the region. Titanium screws can help keep the bone block in place. Over a period of several months the bone is healed and the jaw is ready to take the implant.
