Guide bone regeneration (GBR) reconstruction of extensive alveolar bone defect due to infected radicular cyst enucleation: 2 case reports.

INTRODUCTION AND

IMPORTANCE

Reconstruction of alveolar bone defects caused by radicular cysts is challenging for oral and maxillofacial surgeons.

CASE PRESENTATION: Two Indonesian females had similar complaint of swelling in the vestibule area of the right mandible. Panoramic radiography showed radiolucent lesions. Participants underwent guided bone regeneration (GBR) reconstruction, which used pericardium membrane in the first case and amnion membrane in the second case. Post-surgery condition showed an improved prognosis and histology showed a radicular cyst.

DISCUSSION: The use of pericardium membrane is easier compared to the amnion membrane, where success requires regular follow-up.

CONCLUSION

Alveolar bone defect reconstruction based on GBR requires meticulous preparation regarding patient condition, case selection and technical comprehension to ensure better treatment outcomes.
