Adaptación marginal del Zirconio

Abstract

At present, due to the increase in aesthetic requirements in oral restorations, metal-free materials have been developed with excellent properties that allow achieving an excellent aesthetic and functional result in the patient, with adequate biocompatibility, resistance and marginal adaptation (Martínez , 2010).

In this sense, marginal adaptation is defined as the degree of proximity of a restorative material to the end line of a dental preparation. According to the ADA (American Dental Association) Accepted <120 μm. Marginal adaptation is a very important factor in the elaboration of dental restorations, since the presence of a marginal gap allows greater accumulation of bacterial plaque, percolation of surcular gingival fluid and in some cases loss of bone, producing microfiltration, recurrent caries and periodontal disease (Raigrodski, 2004).

Likewise, the marginal adaptation of crowns is extremely important and depends on both the material and the technique used for its manufacture, since this ensures good long-term clinical performance, therefore it is important to know the average marginal adaptation with each technique. in order to select the most appropriate technique for this material. For this reason, it is proposed to carry out this research in order to determine the dental marginal adaptation in zirconium copings, taking into account the use of different systems for its realization, such as the cerec and zirconzahn systems.
