Incidencia de invasión del espacio biológico por coronas metálicas prefabricadas. Clínica Odontopediatría. UCSG B-2017.

Abstract

The aim of this study was to evaluate the presence or absence of gingival biological depth invasion caused by prefabricated metallic crowns. MATERIALS AND METHODS: This study was designed as an observational, descriptive analysis of data collected by the author. The sample was composed by 50 pediatric patients attended in the dental clinic of the Universidad Católica Santiago de Guayaquil in the B-2017 period. RESULTS: 50 children from ages 3 – 12 years were examined, 21 girls (42%) and 29 boys (58%). Relating the invasion of the biological depth with the probing depth post cementation, we could see that there was a larger percentage (80%) in the parameter above 1. Analyzing the predisponent factors that can cause an invasion of the biological depth, we found that the most frequent cause was an incorrect marginal adaptation (46%). CONCLUSION: We can conclude that in the process of cementation of metallic crowns, the correct parameters were not followed; students didn´t accomplish a correct marginal adjustment, which gave us a high percentage of invasion of the biological depth as a result.
