Anchoring the Crown: Omega Loop Post for Strip Crown Reconstruction in Severe Early Childhood Caries: A Case Report

Severe early childhood caries can leave insufficient tooth structure to retain restorations of primary anterior teeth. This case describes the use of omega-loop posts for intracanal retention of composite resin strip crowns following pulpectomy. We reported a 3-year-old girl presented with extensive carious destruction of the maxillary anterior teeth and fracture of one tooth after a fall. Clinical and radiographic examinations revealed pulp necrosis in both maxillary primary central incisors. Both teeth underwent pulpectomy, followed by omega-loop post placement and strip crown reconstruction to restore form, aesthetics, and function. The technique involved simple chairside fabrication and limited treatment time, supporting restoration despite substantial loss of coronal tooth structure. All procedures were performed chairside without general anaesthesia through brief, staged visits with age-appropriate behavioral guidance. At approximately three months after rehabilitation, all crowns were clinically satisfactory. At the latest follow-up, 10 months after restoration of tooth 51 and 8 months after restoration of tooth 61, both omega-loop-supported crowns remained intact and adequately retained, without clinically detectable mobility, gingival swelling, abscess, or recurrent caries. In conclusion, omega-loop-supported crowns maintained satisfactory short-term retention despite extensive coronal loss. This case supports clinical feasibility but cannot establish long-term durability or superiority over other post systems.
