Bone Grafts and Sinus Lifts

Bone graft and Sinus Lifts

Patients with insufficient, healthy bone to support dental implants could be ideal candidates for bone grafts, which is the process of rebuilding the bone.


Reasons for insufficient bone:

  • Previous oral conditions, such as gum or periodontal disease

  • Injury or trauma to your face and jaw

  • Teeth extracted and left the spaces empty

  • Worn dentures



Bone grafting is generally a painless, minimally invasive procedure. The process begins with a local anesthetic to numb the area and an incision in the gum tissue is made to expose the bone. The dentist attaches the bone graft material to the exposed bone in the mouth, which contains collagen and proteins that encourage bone growth, and then the area is sutured to close the gum tissue.

As new bone grows, it replaces the graft material, which is absorbed completely. The new bone can take from a few weeks up to months to heal.


Types of Grafts:

  • Alloplast:  a graft composed of synthetic, non-human material

  • Autograft:  a graft involves taking bone from another part of the patient’s body

  • Allograft: When the bone comes from another person

  • Xenograft: a graft involves taking bone from an animal


Dental Procedure to support Bone Growth

  • Sinus lift: which increases the height of the bone in your upper jaw above the premolar and molar teeth to support placement of dental implants.

Care and Treatment

  • Healing takes between 6 – 9 months

  • Antibiotics and mouthwash may be prescribed to prevent infection and pain medication to alleviate discomfort
