Bone Grafting for Dental Implants

Building the Foundation
for an Implant

A dental implant requires adequate bone volume and density to achieve stability. When a tooth has been missing for some time — or was lost due to infection, trauma, or gum disease — the jawbone begins to resorb (shrink). If this bone loss is significant, the site may not have enough bone to hold an implant.

Bone grafting is the procedure of adding bone material to the deficient area — encouraging the body to grow new bone. Once healed, the site has sufficient volume and density for a successful implant placement.

This is not always required. Many patients — including those with significant bone loss — can avoid grafting through All-on-4 angled implant protocols, shorter implants, or other strategies. Dr. Sumit Firke will only recommend grafting when it is clinically indicated — and will explain exactly what is needed and why.

The jawbone is stimulated by the forces transferred through tooth roots during chewing. When a tooth is lost, that stimulation stops — and the bone in that area begins to resorb within weeks. Studies show:

This is one of the key reasons implants are recommended early — the longer you wait after tooth loss, the more bone you lose and the more complex the eventual treatment.

Socket Preservation Graft

Performed at the time of tooth extraction. Bone graft material is placed into the empty socket to preserve the bone volume during healing. Prevents the 25% width loss that otherwise occurs in year one. Significantly reduces or eliminates the need for more complex grafting later.

Sinus Lift (Sinus Augmentation)

For upper back teeth (molars, premolars). The maxillary sinus is the air-filled cavity above the upper jaw. When upper back teeth are lost, the sinus can expand downward into the space — leaving insufficient bone height. A sinus lift adds bone below the sinus membrane to create adequate height for implant placement.

Lateral / Onlay Block Graft

For significant horizontal bone deficiency — where the ridge is too narrow. Bone block (autogenous from another site, or synthetic) is placed alongside the existing bone to widen it. Healing time: 4–6 months before implant placement. Used for cases with severe resorption.

Simultaneous GBR (Guided Bone Regeneration)

Bone graft placed at the same time as the implant, for minor deficiencies. A membrane is placed over the graft to guide bone growth and exclude soft tissue. Reduces the number of surgeries — graft and implant in one visit where clinically appropriate.
