ALDANA SEPULVEDA, H.  and  GARZON RAYO, H.. Impression making in fixed prosthesis: periodontal approach. Av Odontoestomatol [online]. 2016, vol.32, n.2, pp.83-95. ISSN 2340-3152.

One of the major successes in prosthodontics is the accuracy of the final restoration toensure the survival of the prosthesis, the precise reproduction of the preparation margins in impressions is a need for good quality marginal requirement. That's why the technique and impression materials, as well as the management of periodontal tissues are key in achieving success. Understanding the properties of each of the materials used for the impression making process and the timely diagnosis of previous periodontal condition (health, disease, periodontal biotype), and techniques available to the retraction or displacementof the gingival tissues, provide clinicians the tools necessary for making decisions and achieving the best aesthetic and functional results in fixed prosthesis. The purpose of this topic review is to propose a series of recommendations for clinical restorative from the periodontal approach, which to establish protocols for the diagnosis, planning and execution of their clinical cases, knowing the current techniques of gingival displacement and takes impression and its effects on the periodontium.

Keywords : Dental impression technics; gingival retraction techniques; dental impression materials; dental prosthesis; periodontium; epithelial attachment; periodontitis; tissue conditioning.
