Restoration of periodontally compromised dentitions using cross-arch bridges. Principles of perio-prosthetic patient management.

Severe periodontal disease often leads to tooth loss, necessitating prosthetic rehabilitation to restore function and aesthetics. The concept of perio-prosthetic treatment using extensive bridges of cross-arch design was introduced approximately 30 years ago. Long term follow-up studies have shown that teeth with reduced periodontal support can be used as abutments for extensive fixed prostheses, provided periodontal disease has been treated successfully, and an effective recall programme has been instituted to prevent periodontal disease recurrence. Low complication rates have been reported with these extensive constructions.
