Caracterização tomográfica das áreas edêntulas previamente à reabilitação com implantes unitários

Abstract

The present cross-sectional study aims to characterize partially edentulous areas, which will be rehabilitated with a dental osseointegrated unitary implant in the aes-thetic maxillary area by means of computed tomography. The parameters evaluated in 14 tomography were: distance from the Cemento-Enamel Junction (CEJ) until the bone Crest (CO), distance between the CO and distance between the crowns of the teeth adjacent to the prosthetic space (PE), the PE bone width and height, thickness of the palate in the region of the second premolars and molars and the vertical thick-ness of the soft tissue in the PE. The results were analyzed by descriptive statistics and Spearman correlation with significance level of 5%. The distribution of teeth evaluated was 35.7% for anterior teeth and 64.3% for posterior teeth. When applied to the correlation tests, low and middle values for the coefficient of correlation (≤ 0.29 and 0.30 ≤ ≥ 0.49, respectively) were found in most comparisons indicating weak correlations. No significance statistic was found for the majority of comparisons. Only for the correlation mucosal thickness EP versus distance between JCE and CO in the tooth mesial to the PE was found moderate correlation (r = 0.56), with statistically significant difference (p = 0.03). Computed tomography of the conical beam is a via-ble tool for maxillofacial region because it allowed the measurement of several pa-rameters of hard and soft oral tissue useful for dental implants treatment planning, increasing the predictability of success in rehabilitators treatments.
