Clinical Case Study

Case Highlight: Cyst Removal and Bone Regeneration (#8 Region)

Clinical Overview
A patient presented with a large cystic lesion associated with tooth #8, resulting in significant bone loss extending from the apical third of the root to the nasal sinus floor. Advanced imaging also revealed mesial root resorption of tooth #8.

Treatment Approach
Tooth #8 was extracted, and the cyst was carefully enucleated. The extent of bone loss included destruction of the buccal bony wall and involvement of the palatal wall. To reconstruct the site and preserve the ridge architecture, a resorbable collagen membrane was first placed along the palatal wall. A mineralized cortico-cancellous particulate bone graft was then gently packed into the area of bone destruction to restore volume and support future regeneration.

The membrane was wrapped over both the occlusal and buccal aspects and stabilized using an internal horizontal mattress suture to secure it in position. Primary closure was achieved with additional fine sutures to protect the graft during early healing.

Outcome
Post-operative CT imaging confirmed successful placement of the graft material in the previous area of bone destruction. The resorbable membrane served to prevent soft-tissue ingrowth and maintain graft stability during the healing phase, allowing bone turnover to occur gradually as the graft resorbed and new bone formed.

Clinical Insight
Guided bone regeneration plays a critical role in preserving structure and function following cyst removal. Proper membrane stabilization and graft selection support predictable bone regeneration — re-establishing a healthy foundation for future restorative options.

In every case, our goal is restoration with respect — rebuilding what was lost while preserving the integrity of the surrounding anatomy.
