Periodontia Curitiba – Esthetic Crown lengthening – Chu´s Gauge

Although human dental anatomy is taught in university curricula, clinicians often witness restorations that are not proportional to one another. Dental restorations should also be proportional to periodontal supporting tissues as an essential aspect of dental anatomy. Measurements can be performed directly on a patient’s teeth with aesthetic gauges used to confirm the correct position of the supporting osseous topography. This article demonstrates a technique using these gauges to objectively determine the correct position of the underlying hard tissues and render predictable, aesthetic treatment.
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.
There is no doubt that this instrument made easier for the surgeons and more predictable for the petients.
