EPPT–CTG regeneration using rhFGF‐2/CO <sub>3</sub> Ap for Cemental Tear Defects: A case report
This case report describes a new treatment method for repairing bone loss around a tooth caused by a "cemental tear," a type of root surface damage that can lead to gum swelling and bone destruction. A 73-year-old male patient was treated with a combination of a growth factor (rhFGF-2), a synthetic bone substitute (CO<sub>3</sub>Ap), and a small piece of gum tissue (CTG) using a minimally invasive surgical technique that preserves the entire gum papilla. Over 12 months, the treatment resulted in significant healing of both bone and gum tissues without recession. This approach may offer a reliable option for saving teeth with similar severe bone defects.
