Introduction: The principles of biologic width have governed the literature and served as a clinical guideline during the evaluation of perio- restorative interrelationships. An adequate understanding of this concept is paramount to ensure adequate form, function, aesthetics and comfort of the dentition. Biologic width violation has become a common problem as most of the practitioners tend to underestimate the amount of tooth structure that must be exposed during a crown lengthening procedure. Also, adding to the confusion, there is a lack of general agreement regarding the amount of tooth structure that must be exposed above the crest of bone for restorative purposes. Aim: The aim of this study was to perform aesthetic crown lengthening using Chu aesthetic gauges and evaluate the healing of biologic width. Materials and Methods: A total of 90 teeth in 15 patients were included into the study of which 30 teeth required crown lengthening and 60 teeth shared a proximal surface with the experimental teeth. Aesthetic crown lengthening was performed using the Chu aesthetic gauges. Presurgical and intraoperative data were recorded at baseline, three and six months at six sites per tooth. Results: The computed data suggest that although the positional changes of the periodontal tissues stabilize by three months, the biologic width if adequate crown lengthening is carried out re-establishes itself by three months to the original vertical levels and further gets stabilized by six months. Conclusion: A step by step approach to periodontal aesthetic crown lengthening using Chu aesthetic gauge can serve to be vital for successful, predictable, and aesthetic restorative outcome.
