A patient presented with a fractured, root canal-treated tooth 24 that was deemed non-restorable. To preserve the ridge architecture for future implant placement, a socket preservation procedure was planned. The preoperative radiograph revealed a pronounced buccal bone deficiency.

Following atraumatic extraction and curettage of the socket, a collacone^® cone was inserted into the alveolus. NOVAMag^® SHIELD was then trimmed and adapted to the defect after preparation of a subperiosteal buccal pouch. The magnesium membrane was positioned to stabilize the buccal contour and maintain the regenerative space. Stabilization sutures were placed and an open healing protocol was performed to support the development of optimal keratinized soft tissue.

Healing progressed uneventfully with stable soft tissue conditions throughout the post-operative phase. Clinical follow-up after 3 months demonstrated excellent healing of the extraction site, while CBCT evaluation confirmed preservation of the ridge contour and regeneration of buccal bone. Implant placement was subsequently performed without the need for additional augmentation procedures. Following an uncomplicated 2-month healing phase after implant placement, optimal conditions for the final prosthetic restoration were achieved.
