Radiological Evaluation of Anterior Maxilla For Immediate Implant Placement

Using a line drawn through the midpoints of the teeth, parallel to their long axes, the anterior crest morphology was assessed. For maxillary central, lateral, and canine teeth, alveolar crest width and height, buccal bone thickness, and tooth-crest angle were measured separately. To determine buccal bone thickness, measurements were taken from the buccal crest apex, the midpoint of the root, and the apex of the tooth. The height of the alveolar crest was defined as the length of a line drawn parallel to the crest's long axis between the nasal fossa floor and the alveolar crest. The width of the alveolar crest was calculated by averaging measurements taken from the midpoints of three equal sections of the alveolar crest. The buccal undercut was determined as the point where the crest came closest to the root in the sagittal plane. Additionally, the angle between the tooth roots and the alveolar crest was measured to determine the root position in the radial plane
