Introduction: One of the most trending advanced bone grafting techniques nowadays is the Split Bone Block Technique (SBBT) or Khoury Technique. Autogenous bone grafting is still the gold standard to achieve the best results in bone regeneration pior to implant placement. Some literature suggests that morbidity associated to the technique may decrease patient acceptance of treatment.
Case Report: In this post, we will show a modification of the technique to improve patient’s quality of life post surgically. We may see the pre-op condition of the defect at tooth 14 after traumatic extraction and the follow-up at 4 months after bone regeneration with bone block harvested from the palatal side of tooth 15. All the principles of SBBT were followed.
Conclusion: The one wound philosophy tries to reduce the morbidity of the patient after a surgical intervention. There are a lot of variable to take in consideration, including volume of bone available at donor site and hight and width of defect, but this technique is for sure one viable option to regenerate bone prior or simultaneously to the implant placement.
