| Primary | Cone beam diagnostic examination | Cone beam diagnostic examination: Millimeter measurements will be taken at Day 0. This examination is an X-ray technique that uses a cone-shaped radiation beam. The measurements will be made on radiographic examinations Mucous measures Vestibular cortical Distance, lingual cortical measured in the middle of the cell Depth of the slot lingual cortical side Depth of the cell vestibular cortical side Bone measures Thickness of the lingual cortical measured caliper 2 millimeters under the rim Vestibular cortical thickness measured with calipers 2 millimeters under the rim Depth of the slot lingual cortical side Depth of the cell vestibular cortical side |
