Guided Bone Regeneration Using Ti-Reinforced PTFE Membrane Vs. Khoury's Technique in Augmentation of Posterior Mandibular Defects

Guided Bone Regeneration Using Ti-Reinforced PTFE Membrane Vs. Khoury's Technique in Augmentation of Posterior Mandibular Defects

The aim of the present clinical trial is to compare two different alveolar ridge bone augmentation techniques for mandibular horizontal bone defects.

Will using PTFE membrane with a mixture of xenograft and particulate autogenous bone result in bone gain similar to standard Khoury's bone shell technique?

Inclusion Criteria:

1. Have one or more missing teeth in the posterior mandibular segment.
2. The alveolar ridge in the edentulous site of the selected patients will have a buccolingual width of less than 5 mm.
3. Sufficient vertical bone height above inferior alveolar nerve.
4. Free of any local or systemic condition that may contraindicate ridge expansion procedure.
5. No sex predilection.
6. The patient will be between the ages of 18-70 years.

Exclusion Criteria:

1. Patients taking any medication that may interfere with bone healing or bone biology.
2. Patients with any systemic disease that may affect bone healing.
3. Any patients with any previous bone grafting procedure at the site of interest.
4. Heavy Smokers (more than 20 cigarettes daily).
5. Patient's that have been diagnosed with periodontal disease, as sufficient ridge height would be improbable.
