After a tooth is lost, the jawbone gradually shrinks. When there is no longer enough volume to stabilise an implant, a bone graft rebuilds it. The 3D scan taken at the clinic shows precisely whether it is needed.
The implant must be fully surrounded by bone to integrate for the long term. A graft is considered when the bone height or width is insufficient.
The bone is no longer stimulated by the root and decreases in height and width over the years.
A chronic infection or traumatic extraction can destroy part of the bone wall.
The sinus often enlarges after the loss of molars and reduces the available bone height.
| The technique | What it allows | The implant |
|---|---|---|
| Socket preservation | Placing a bone substitute at the time of extraction to limit bone loss. | Placed later, on preserved bone |
| Guided bone regeneration | Rebuilding bone width with a filling material protected by a membrane. | Often placed at the same time |
| Sinus lift | Lifting the sinus membrane and filling the space to gain height under the upper molars (crestal or lateral approach). | At the same time or after a few months |
| Bone maturation | Letting the graft turn into solid bone before placing the implant. | Timeline explained at the assessment |
The 3D scan measures bone to a tenth of a millimetre: the decision to graft is based on measurements, not estimates.
Short implants, tilted implants or All-on-4: when a reliable alternative exists, it is offered to you.
When a graft is needed, the implant position is planned in advance so that grafting is done only where it is useful.
Many patients have enough bone for direct placement. Only the 3D scan can tell for certain: it is the first step of your assessment.
The procedure is carried out under local anaesthesia. In the following days, moderate swelling and discomfort are possible; they are controlled by the prescribed treatment.
Most often it is a bone substitute of natural or synthetic origin, sometimes combined with bone taken locally. The chosen material is explained to you before the procedure.
It depends on the technique: the implant can be placed on the day of the graft, or after a maturation period of a few months. The timing is set at the assessment.
Like any surgery, it carries risks, notably perforation of the sinus membrane. Planning on CBCT and a technique adapted to your anatomy greatly reduce them.
No. Many patients have enough bone for direct placement. Only the 3D scan can tell for certain.
