This clinical study consists on taking 2 different records of the upper and lower incisors area : 1) a perpendicular x-ray and 2) an ultrasonic measurement of gingival thickness on the labial plate. Both measurements are used in order to measure gingival and bone thickness. The aim was to verify the reliability of the tissue measurements of an ultrasonic technique compared with the radiographic technique and to verify whether the biotype has correlation between the maxillary and mandibular biotype in the same patient.
