Interpositional Grafting: Addressing Bone Height Deficiency
When implant placement is needed but the available jawbone height is inadequate, advanced techniques like bone grafting offer an effective remedy. This procedure is tailored for patients lacking the bone volume necessary to securely support implants, whether in the upper or lower jaw.
At Smilo Dental Implants London, we employ the interpositional graft—often called the “sandwich technique”—to enhance vertical bone height in cases where conventional grafting may fall short. The method involves carefully separating a section of existing jawbone to create a space between the two layers, where bone graft material is inserted. After healing, this augmented bone provides a robust foundation for implant placement.
This specialised technique demands precision, expertise, and meticulous pre-surgical planning. Unlike traditional grafting that builds bone volume gradually, interpositional grafting allows for more immediate and stable augmentation, improving the likelihood of successful, long-lasting implants.
Our team utilises detailed 3D imaging and clinical evaluations to determine if this approach suits your individual needs.
Step-by-Step Overview of Interpositional Bone Grafting
- Consultation & Imaging: Comprehensive assessment using CT scans and X-rays to evaluate bone dimensions and implant suitability.
- Surgical Planning & Site Preparation: Formulation of a precise treatment plan and identification of the graft area.
- Bone Segmentation (“Sandwich Technique”): A controlled separation of a jawbone segment to create space for the graft.
- Graft Placement & Augmentation: Insertion of graft material—autogenous, allograft, or synthetic—between bone layers to increase height.
- Stabilisation & Healing: The site is secured with microplates or screws, allowing 3 to 6 months for optimal bone integration.
- Implant Placement: Once healed, implants are placed into the new bone, ensuring secure, long-term function

What to Expect After Surgery:
✅ Mild swelling and discomfort for several days, controllable with prescribed medication.
✅ Soft diet during the initial recovery to reduce pressure on the surgical site.
✅ Follow-up appointments to monitor bone healing and graft integration.
✅ Avoidance of smoking and alcohol to promote effective recovery. -
Why Choose Interpositional Grafting?
🔹 Restores bone height, enabling implant placement despite severe bone loss.
🔹 Provides a stronger, more stable base compared to traditional grafting.
🔹 Minimises the need for more invasive alternatives like zygomatic implants.
🔹 Increases implant success rates by enhancing bone integration
