Non-syndromic multiple tooth impaction treated with digitally designed subperiosteal implants: A two-year follow-up case report

Abstract

Rehabilitation of a patient with multiple impacted and retained teeth presents a major clinical challenge, particularly when conventional endosseous implants are not feasible due to anatomical limitations. This case report describes a rare presentation of a young female patient with generalized multiple impactions in the absence of any systemic or genetic condition. Comprehensive testing ruled out syndromic etiologies. A two-stage surgical protocol was followed: extraction of impacted teeth and placement of digitally designed subperiosteal implants. Fixed full-arch prostheses were delivered with excellent functional and esthetic outcomes. Follow-ups at two years confirmed implant stability, healthy soft tissue, and high patient satisfaction. To our knowledge, this is among the few reported cases that integrate digital subperiosteal implant planning in non-syndromic multiple impactions. This case highlights the value of individualized digital planning and the resurgence of subperiosteal implants in complex cases where traditional implant therapy is contraindicated.
