Interpositional Graft: A Solution for Insufficient Bone Height
When dental implants are needed but jawbone height is inadequate, advanced surgical techniques such as interpositional grafting offer an effective solution. This procedure is designed for patients lacking sufficient bone volume to support implants, whether in the upper or lower jaw.
At Smilo Dental Implants Leeds, we use interpositional grafts to increase bone height in cases where traditional bone grafting might not be enough. Often called the “sandwich technique,” this method involves carefully separating a section of the existing jawbone to create space for inserting a bone graft between the two layers. Once healed, the added bone provides a strong foundation for secure implant placement.
Interpositional grafting is a highly specialised procedure requiring precision, expertise, and thorough pre-surgical planning. Unlike conventional grafts that build bone gradually, interpositional grafts offer a more direct and stable augmentation, improving the chances of long-term implant success.
Our expert team at Smilo Dental Implants Leeds will perform detailed 3D imaging and clinical evaluations to determine if this technique suits your needs.
Step-by-Step Process of Interpositional Bone Grafting
- Initial Consultation & Imaging: Comprehensive CT scans and X-rays assess bone height, density, and implant suitability.
- Surgical Planning & Site Preparation: A tailored treatment plan is developed, identifying the augmentation area.
- Bone Segmentation (“Sandwich Technique”): A small section of the jawbone is carefully separated to create a gap for the graft.
- Graft Placement & Bone Augmentation: Bone graft material (autogenous, allograft, or synthetic) is inserted between the bone layers to increase height.
- Stabilisation & Healing: Microplates or screws secure the site, allowing for optimal healing and integration over 3 to 6 months.
- Implant Placement After Maturation: Once healed, implants are placed in the newly augmented bone for lasting stability and function.

What to Expect After Surgery:
✅ Mild swelling and discomfort for a few days, manageable with prescribed medication.
✅ Soft diet during initial healing to reduce pressure on the site.
✅ Regular follow-ups to monitor bone integration and healing progress.
✅ Avoid smoking and alcohol to support effective recovery. -
Why Consider Interpositional Grafting?
🔹 Restores lost bone height, enabling implant placement in cases of severe deficiency.
🔹 Provides a stronger, more stable foundation than conventional bone grafts.
🔹 Minimises the need for more invasive procedures such as zygomatic implants.
🔹 Increases implant success rates due to better bone integration.
