Interpositional Grafting: Overcoming Insufficient Bone Height
When bone height in the jaw is inadequate for implant placement, advanced surgical options like interpositional bone grafting offer an effective remedy. This method is designed for patients with insufficient bone volume, commonly affecting either the upper or lower jaw.
At Smilo Dental Implants Cardiff, we employ interpositional grafts to enhance vertical bone dimension where conventional grafting may fall short. Often called the “sandwich technique,” this procedure involves delicately separating a segment of the existing jawbone to create space for a bone graft between the layers. Following healing, this augmented bone provides a secure base for implant placement.
Interpositional grafting is a complex procedure requiring expert skill and meticulous preoperative planning. Unlike traditional grafts that gradually build bone volume, this technique allows for a more stable and immediate augmentation, improving the prospects for successful long-term implant integration.
Our skilled team at Smilo Dental Implants Cardiff will conduct thorough 3D imaging and clinical assessments to determine if this method suits your individual needs.
Step-by-Step Overview of Interpositional Bone Grafting
- Initial Consultation & Imaging: Comprehensive evaluation via CT scans and X-rays to assess bone quality and implant feasibility.
- Surgical Planning & Preparation: Detailed treatment plan developed and the graft site identified.
- Bone Segmentation (“Sandwich Technique”): A precise cut separates a section of jawbone to create space for the graft.
- Graft Placement & Augmentation: Bone graft material (autograft, allograft, or synthetic) inserted between bone layers to increase height.
- Stabilisation & Healing: Microplates or screws secure the site, supporting a 3 to 6-month healing period for bone integration.
- Implant Placement: After full healing, implants are positioned in the new bone to ensure long-lasting stability.

Post-Surgery Expectations and Care:
✅ Expect mild swelling and discomfort during the initial days, controllable with prescribed medications.
✅ Follow a soft-food diet to avoid pressure on the surgical area during early healing.
✅ Attend scheduled follow-up appointments to track healing and bone development.
✅ Avoid smoking and alcohol, as they can impair the healing process -
Why Choose Interpositional Bone Grafting?
🔹 Restores vertical bone height, enabling implant placement in cases of severe deficiency.
🔹 Provides a stronger and more reliable foundation than standard grafting.
🔹 May reduce the necessity for more extensive surgeries such as zygomatic implants.
🔹 Enhances implant success through improved bone integration.
