VILLAVERDE RAMIREZ, G. et al. Surgical treatment of clincial short crowns: techniques of coronary lengthening. Avances en Periodoncia [online]. 2000, vol.12, n.3, pp.117-126. ISSN 2340-3209.

The so called clinic short crowns and/or those dental pathological processes whose limits can be subgingivalor even underosseous, are a frenquent problem in dental office. Diferent causes produce them, being the most frequent: decay, dental fractures and altered passive eruption. The reasons for their treatment are usually prostodontics and/or restorative dentistry although very often, our patients come to us for esthetical reasons. The surgical technique leading to their correction is called "crown lengthening technique". In this article we will analize the morphological and biological principIes which rule their justification, their limits, as well as the own surgical handlings we must carry out.
