When you have lost teeth over the years, the jawbone gradually resorbs as it is no longer stimulated by the teeth. Therefore, the bone mass may not be thick enough to accommodate a dental implant. This is when a bone graft is performed.
Frequently asked questions about bone grafts
How is a bone graft performed?
During a procedure, the dentist will graft bone (human bone, from the patient or from an external donor) onto the area to be filled. Once the bone graft is in place, the surgeon can proceed with placing the dental implants.
Is bone grafting necessary in all cases of dental implant placement?
No. The dentists and other professionals at Lapointe Dental Centres will make sure you undergo an X-ray to determine if a dental bone graft is necessary.
The maxillary sinuses are bony cavities located above the upper jaw. When teeth are missing, the maxillary sinus tends to swell and expand, which reduces bone mass and increases the difficulty of installing a dental implant.
After a thorough examination and a maxillofacial X-ray, the dentist may suggest a sinus lift. This surgical procedure involves pushing on the maxillary sinus to elevate it and grafting bone onto the thinned portion of the upper jaw to allow for the placement of a dental implant without the risk of damaging the sinuses.
