Brief Summary

According to the literature age and gender may be associated with differences in skeletal size, anatomy and architecture in humans. However, little is known about the synergistic effects of age and gender on the healing capacity of maxillary bones, since most of the preclinical studies are focused on each variable separately. The present study radiologically evaluated various parameters such as alveolar crest height and width, buccal bone thickness, degree of buccal undercut, and root-crest angle using cone-beam computed tomography (CBCT) in a large patient population, and compared these parameters across different age and gender groups to analyze the effect of aging and gender on the bone morphology in the anterior maxillary region.

Outcome Measures

Primary Outcomes (5)

• Alveolar Crest Height

  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.

  One year

• Alveolar Crest Width

  The width of the alveolar crest was calculated by averaging measurements taken from the midpoints of three equal sections of the alveolar crest.

  One year

• Buccal Bone Thickness

  To determine buccal bone thickness, measurements were taken from the buccal crest apex, the midpoint of the root, and the apex of the tooth.

  One year

• Buccal Undercut Depth

  The buccal undercut was determined as the point where the crest came closest to the root in the sagittal plane.

  One year

• Root Position

  the angle between the tooth roots and the alveolar crest was measured to determine the root position in the radial plane

  One year

Interventions

radiological evaluation OTHER

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
