Abstract

AGUILERA-MUNOZ, Felipe; URIBE-ESPINOZA, Sergio  and  SANDOVAL-VALDES, Felipe. Diagnostic Agreement of Bone Measurements for Dental Implants by Cone-Beam Computed Tomography. Int. J. Odontostomat. [online]. 2020, vol.14, n.1, pp.89-94. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2020000100089.

The aim of this study was to determine the degree of agreement between professionals for bone measurement analysis by Computed Beam Computed Tomography (CBCT). A diagnosis agreement study was carried out with the participation of 32 dental surgeons from the Los Ríos region, all specialists in implantology. The dental surgeons carried out measurements of bucco-palatal thickness, mesio-distal distance and height in a CBCT examination with a 2 week interval, in order to estimate intraclass correlation coefficient (ICC). Through the BlandAltman method the analysis of the individual differences for each of the indicated measurements was realized. Finally, to establish statistically significant differences between the measurements, t-test was performed for paired samples, with a statistical significance level of p <0.05. The ICC for buccopalatal thickness measurements was 0.71, while for the mesiodistal distance measurements it was 0.79, and height was 0.62. The general ICC for the three measurements was 0.97. No statistically significant differences were found in the evaluated measurements. In conclusion, there is a high level of agreement among professionals for measurements based on Cone Beam Computed Tomography (CBCT).
