Interpositional Graft: Restoring Bone Height for Implants
When dental implants are needed but there’s insufficient bone height in the jaw, advanced procedures such as interpositional grafting offer a practical solution. This method is designed for patients who do not have enough bone volume to support implants, especially in the upper or lower jaw.
At Smilo Dental Implants Bristol, we specialise in using interpositional grafts to increase bone height in cases where conventional grafting methods might not be enough. Also known as the “sandwich technique,” this approach involves carefully separating a section of the existing jawbone to create space for a bone graft to be placed between the two layers. Once healed, the added bone structure provides the necessary foundation for the secure placement of dental implants.
Interpositional grafting is a highly specialised procedure requiring precision, expertise, and thorough pre-surgical planning. Unlike traditional bone grafting, which gradually builds bone volume, interpositional grafts provide a more immediate and stable solution, improving the likelihood of long-term implant success.
Our expert team at Smilo Dental Implants Bristol uses advanced 3D imaging and clinical assessments to determine if interpositional grafting is the right choice for you.
Step-by-Step Process of Interpositional Bone Grafting
- Initial Consultation & Imaging – We conduct a detailed assessment using CT scans and X-rays to evaluate bone height, density, and suitability for implants.
- Surgical Planning & Bone Site Preparation – A tailored treatment plan is created, and the area requiring augmentation is precisely identified.
- Bone Segmentation (“Sandwich Technique”) – A small section of the jawbone is carefully separated to create space for the bone graft.
- Graft Placement & Bone Augmentation – A bone graft material (autogenous, allograft, or synthetic) is inserted between the separated layers of bone to restore height.
- Stabilisation & Healing Process – The surgical site is secured with microplates or screws to ensure optimal healing and bone integration. The healing period typically lasts between 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 and functionality.

What to Expect After Interpositional Grafting Surgery:
✅ Mild swelling and discomfort for a few days, which can be managed with prescribed medication.
✅ A soft food diet during the initial healing phase to minimise strain on the surgical site.
✅ Regular follow-up visits to monitor the progress of bone integration and healing.
✅ Avoidance of smoking and alcohol, as these can impede the healing process. -
Why Consider Interpositional Grafting?
🔹 Restores lost bone height, enabling implant placement even in cases of significant bone deficiency.
Provides a stronger and more stable foundation than traditional grafts.
Reduces the need for more invasive procedures, like zygomatic implants.
Improves implant success rates due to enhanced bone integration.
If you’ve been advised that your bone height is insufficient for implants, book a consultation today to see if interpositional grafting is the right solution for you.
