Chu-aesthetic gauges: The precision implement for aesthetic crown lengthening and evaluation of biologic width

Chu aesthetic gauges are one of their own kind and unique set of devices that uses adequate crown proportions to determine the exact position of the osseous contour supporting the teeth in concern. The aim of this study was to perform aesthetic crown lengthening using these gauges and evaluate the healing of biologic width. 15 systemically healthy patients participated in this study. Aesthetic crown lengthening was performed in the maxillary anteriors using these gauges. Along with this evaluation of level of biologic width was done at baseline, 3months and 6 months. The literature indicated that even though periodontal tissue remodels after surgery and positional changes are noted but they get stabilized after three months. Besides this, the biologic width re- establishes itself to original vertical levels by 3 months and it attains a proper state of equilibrium in about 6 months. The authors concluded that it was possible using Chu-aestehtic gauges, to achieve ideal crown length-width ratio. At the same time it yielded a beneficial biologic width level for future restorative or prosthetic purpose. The unique approach by these gauges is an innovative and novel method in modern era
