Not enough bone for an implant — what can be done?

What “not enough bone” means

An implant needs suitable space in the jawbone. Height, width and conditions at the planned site all matter. Bone volume can decrease after a tooth is lost. An examination and appropriate images help assess the change.

“Not enough bone” does not automatically mean one particular operation. Ask the dentist to show where the problem is and how it affects the proposed restoration. The appearance of the gum alone cannot establish this.

What bone grafting is for

Bone augmentation aims to create the conditions needed for further treatment. The dentist may use your own bone, a substitute material or a combination. Some methods also use a membrane to protect the prepared area.

Ask where the material comes from and what it does. Mention any personal or religious concerns about animal-derived materials before surgery. Choosing a method requires a discussion of its options and limitations.

A sinus lift concerns the back of the upper jaw

A sinus lift raises the membrane lining the maxillary sinus to create space for additional bone underneath. The sinus is an air-filled space above the upper back teeth.

Different approaches are available. The conditions at the site determine the approach and whether an implant can be placed at the same time. The labels “open” and “closed” alone are not enough to compare individual treatment plans.

Why two operations may be needed

A smaller graft can sometimes be combined with implant placement. With more extensive preparation or particular conditions, grafting may be done first, with the next stage planned after healing.

This can add months to treatment. The timetable should explain what you are waiting for and what will be checked before proceeding. The date of the graft is not the date of fitting the final crown.

Healing belongs in the plan too

Pain, swelling and bruising may follow surgery. You will receive instructions about eating, cleaning and medicines. Surgery near the sinus may involve additional restrictions, including nose blowing; the treating team determines their duration.

Ask which symptoms need a call to the practice. Increasing pain or swelling, fever and persistent bleeding should be reported. A graft may not produce enough bone or may need further treatment; this possibility should also be discussed.

Ask about alternatives and the complete cost

• What is the aim of grafting in my case?
• Can it be combined with implant placement?
• Which materials will be used, and why?
• What replacement is planned during healing?
• Is there another plan, such as a different type of tooth replacement?
• What is included in the cost, and how might the timetable change?

Base your decision on your examination

Other people’s experiences can help you prepare questions but do not show the conditions in your mouth. Ask for a clear explanation. You should understand why an additional stage is proposed before agreeing to it.
