Periodontal disease results in attachment loss and damage to the supporting alveolar bone leading to tooth mobility. In majority of cases, the mandibular incisors are the teeth showing the first signs of mobility. The clinical management of periodontally involved teeth remains a challenge to the clinician. Splinting may be indicated for individual mobile tooth as well as for the entire dentition. The main objectives of splinting include decreasing patient discomfort, increasing occlusal and masticatory function, enhancing esthetics and improving the periodontal prognosis of mobile teeth. Fiber-reinforced composites provide one of the better alternatives for splinting of teeth. This clinical report describes a technique of splinting of periodontally involved mandibular anterior teeth using glass fiber-reinforced composite resin with a follow-up period of five years.
