Abstract:
Objective: To present a modified option to surgical crown lengthening for repair of biologic width loss. Methods: The alternative to the traditional method involves reshaping the fractured root surface in combination with conservative removal of the supporting alveolar bone to rebuild the biological width. Although these teeth were considered as not suitable for the traditional methods, 7 teeth from 7 patients with fracture surface located lower than alveolar bone crest were treated by this modified method of surgical crown lengthening. Restoration was accomplished on these teeth two month later. Periodontal index such as tooth mobility, plaque index, probing depth and bleeding index were recorded and followed up. Results: The mean follow-up period was 17 months (ranged from 10 to 31 months). Result of surgery and restoration of these 7 teeth was satisfactory. The gingival tissue remained healthy and esthetic with good function. Conclusion: This modified surgical crown lengthening can be used as an alternative to the traditional method to save more fractured teeth.
