Interpositional Grafting: Restoring Bone Height for Implant Placement
When the bone height in the jaw is insufficient for dental implants, advanced techniques like interpositional bone grafting offer a highly effective solution. This procedure is particularly beneficial for patients who have inadequate bone volume in the upper or lower jaw and cannot proceed with traditional implant placement.
At Smilo Dental Implants Nottingham, we use interpositional grafts to increase bone height in cases where standard bone grafting methods may not be enough. Known as the “sandwich technique,” this approach involves carefully separating a section of the existing jawbone, creating a space into which bone graft material is inserted. Once the graft has integrated and healed, this added bone provides a secure foundation for dental implants.
Interpositional grafting is a precise and advanced procedure that demands expert knowledge and careful pre-surgical planning. Unlike traditional bone grafting, which gradually builds bone volume, interpositional grafting provides immediate, stable augmentation, significantly improving the chances of long-term success with dental implants.
Our highly experienced team at Smilo Dental Implants Nottingham conducts thorough 3D imaging and clinical evaluations to determine whether interpositional bone grafting is the right solution for your specific needs.
Step-by-Step Process of Interpositional Bone Grafting
- Initial Consultation & Imaging – A comprehensive evaluation using CT scans and X-rays to assess bone height, density, and suitability for implants.
- Surgical Planning & Site Preparation – A detailed treatment plan is devised, and the exact area requiring augmentation is identified.
- Bone Segmentation (“Sandwich Technique”) – A small section of the jawbone is carefully separated, creating a controlled gap for the insertion of the bone graft.
- Graft Placement & Bone Augmentation – Bone graft material (either autogenous, allograft, or synthetic) is placed between the separated layers of bone to increase height.
- Stabilisation & Healing – The surgical site is secured with microplates or screws to ensure proper healing and integration of the new bone, typically requiring a healing period of 3 to 6 months.
- Implant Placement After Bone Maturation – Once fully healed, dental implants are placed into the newly augmented bone, ensuring long-term stability.

What to Expect After Interpositional Bone Grafting Surgery:
✅ Mild swelling and discomfort for the initial few days, which can be managed with prescribed medication.
✅ A soft diet is recommended during the early healing phase to minimise strain on the surgical site.
✅ Regular follow-up visits to monitor bone integration and healing progress.
✅ Avoidance of smoking and alcohol, as these can hinder the healing process. -
Why Consider Interpositional Grafting?
🔹 Restores Bone Height – Perfect for patients with significant bone loss, allowing implant placement where it would otherwise not be possible.
🔹 Stronger Foundation – Offers a more stable and durable base for implants compared to conventional grafting techniques.
🔹 Reduces Need for Invasive Procedures – Can eliminate the need for complex procedures, such as zygomatic implants.
🔹 Higher Success Rates – The technique ensures improved bone integration, leading to higher rates of implant success.
