简要总结
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.
详细描述
Aim: The aim of this present study was to radiologically evaluate the socket morphology that may have a clinical impact on the outcomes of immediate implant placement in the anterior maxilla, using cone-beam computed tomography (CBCT) in a large patient population. Moreover, the parameters were compared between different age and gender groups to analyze the effect of aging and gender on the bone morphology around the maxillary anterior teeth.
Material and Methods
This study evaluated a total of 1,668 teeth in the esthetic region, including bilateral central incisors, lateral incisors, and canines in the upper anterior region, using CBCT images from 278 individuals. CBCT images were grouped into age ranges of 20-29, 30-39, 40-49, 50-59, 60-69, and 70-80 years. The morphology of the anterior ridge was assessed by separately measuring alveolar ridge width and height, buccal bone thickness, tooth-crest angle, and buccal undercut for maxillary central incisors.

结局指标
主要结局
Alveolar Crest Height
时间窗: One year
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.
Alveolar Crest Width
时间窗: One year
The width of the alveolar crest was calculated by averaging measurements taken from the midpoints of three equal sections of the alveolar crest.
Buccal Bone Thickness
时间窗: One year
To determine buccal bone thickness, measurements were taken from the buccal crest apex, the midpoint of the root, and the apex of the tooth.
Buccal Undercut Depth
时间窗: One year
The buccal undercut was determined as the point where the crest came closest to the root in the sagittal plane.
Root Position
时间窗: One year
the angle between the tooth roots and the alveolar crest was measured to determine the root position in the radial plane
