Abstract
Background: Implant rehabilitation in the posterior maxilla with severe atrophy remains a clinical and surgical challenge. Although widely used, the lateral window sinus lift is linked to longer healing times, increased invasiveness, and higher morbidity. This study aimed to introduce the Champagne Cap Technique, an innovative variation of the crestal maxillary sinus lift, which allows implant placement in ridges with less than 5 mm of residual bone height.
Case report: This case report details a complex implant placement in a 70-year-old woman with systemic hypertension, a smoking habit, moderate dental anxiety, and limited mouth opening. The patient was treated with a crestal approach, screw expansion, hydraulic grafting using calcium phosphosilicate putty, and primary implant stabilization via a modified X-shaped mattress suture. Five-year clinical and radiographic follow-up showed complete osseointegration, stable bone regeneration, and no complications.
Conclusions: The Champagne Cap Technique is a minimally invasive, effective, and predictable alternative for implant placement in patients who are contraindicated for lateral sinus lift procedures, especially those with compromised systemic health.
