Preservazione con collagene riassorbibile del sito postestrattivo prima del posizionamento di impianti a carico immediato in zone estetiche* Presentazione di un caso e valutazione istologica a 4 mesi

The membranes of barrier made by resorbable collagen proved suitable procedures for use in guided tissue regeneration (GTR) and like correction of anatomical defects.This article calls for the use of absorbable collagen plugs for use in extraction sockets to maintain the volumes of the bone ridge and allow the placement of implants in the frontal areas with better appearance. We explain how to use this material. To this end we presente the characteristics of the material and argue indications and contraindications. We show a case of practical application of these principles and the details of this technique. The objective of this study is to present a technique, that, used in appropriate cases, is easily applicable and allows to obtain better aesthetic result in the rehabilitation of immediate loading at the stage of provisional prosthesis.
