Introduction
Traumatic bone cyst is a pseudocyst which is characterized as an asymptomatic unilocular single lesion with an empty cavity without epithelial lining. Its etiology is still debated, it is more frequent among young people and it is often localized in the posterior mandible zone. A case report is described about diagnosis and conservative treatment of a traumatic bone cyst in anterior zone of lower mandible.
Case Presentation
The report describes a 22‐year‐old female with a traumatic bone cyst in anterior mandible as accidental discovery from a routine orthopantomography. A conservative approach was conducted to treat the lesion through a submarginal incision, an osteotomy with ultrasound, a filling of the cavity with advanced platelet‐rich fibrin membranes, and repositioning of the cortical bone. The radiological follow‐up to 6 months confirmed the healing of the lesion.
Conclusion
The conservative approach through submarginal incision, osteotomy with ultrasound, filling with A‐PRF+ membranes and repositioning of cortical bone ensures optimal bone healing and avoids gingival recessions at six months follow‐up, showing to be a good alternative for satisfactory defect resolution in similar clinical cases.
