Introduction- Crown lengthening is a surgical process designed to extend the extent of supra-gingival tooth construction for esthetic and restorative functions. Based mostly on the scientific situation, crown lengthening process is categorized as both esthetic or practical. Esthetic crown lengthening is normally achieved within the anterior esthetic zone of oral cavity, the place the key concern is to cut back extreme gingival show and improve the scientific crown peak. Whereas practical crown lengthening is finished to show the crown construction so {that a} practical prosthesis might be positioned over the uncovered crown. Preservation of biologic width is the therapeutic endpoint of each these procedures. Crown lengthening might be restricted to gentle tissue solely, or each gentle and exhausting tissue might be contoured.

Indications- There are a number of indications together with: restorative wants, to extend scientific crown peak misplaced because of caries, fracture or put on, to entry sub-gingival caries, to entry a perforation within the coronal third of the foundation, to relocate margins of restorations which can be impinging on organic width, esthetics, quick tooth, uneven gingival contour and gummy smile.

Therapy Modality- Crown lengthening process can achieved both by way of a periodontal knife/scalpel, rotary coarse diamond bur, electrosurgery and so on. These methods have sure disadvantages like surgical trauma, postoperative ache and swelling, bleeding throughout surgical procedure, poor affected person acceptance and likewise coronal migration of the gentle tissue margins is seen throughout therapeutic which makes it tough for recording the end traces after the tooth preparation.

With current developments, standard methods are changed by LASERS which provides a comparatively cold surgical process, sterilization of the wound website, minimal swelling, discount of surgical time, excessive affected person acceptance, diminished postoperative ache and far lesser want of post-operative drugs.

PIOON Laser provides totally different wavelengths like 450nm/810nm or 980nm. Out of which 450nm can utilized in non-contact or contact mode whereas 810nm and 980nm are utilized in contact mode so as to carry out a crown lengthening process. Probably the most fascinating amongst them is 450nm wavelength because of sooner slicing and lesser thermal injury because of non-contact mode of operation.

Within the current case, scientific and radiographic analysis revealed sufficient keratinized gingiva, presence of sub-gingival caries and insufficient tooth construction on the lingual aspect of decrease left first molar. Firstly evaluation of biologic width was achieved by probing to the bone stage (known as “bone sounding”) and subtracting the sulcus depth from the ensuing measurement.
