The preliminary study for three-dimensional alveolar bone morphologic characteristics for alveolar bone restoration

Area of Science:

• Oral and Maxillofacial Radiology
• Dental Implantology
• Anatomical Studies

Background:

• Establishing ideal alveolar bone morphology is critical for successful dental reconstructions, aiming to maximize esthetics and function.
• A standard reference for alveolar bone structure is needed for accurate diagnosis, implant placement, and bone augmentation planning.

Purpose of the Study:

• To evaluate normal alveolar bone structure and provide a standard reference for diagnosing implant placement.
• To guide bone augmentation procedures and the production of prostheses using 3D imaging assessment.

Main Methods:

• Multi-detector computed tomography (MDCT) was used to assess alveolar bone horizontal widths in 22 participants (11 male, 11 female).
• Measurements were taken at crestal, mid-root, and root apex levels for both maxilla and mandible.
• Tooth dimensions and interdental alveolar bone crest widths were also measured and statistically analyzed.

Main Results:

• Maxillary palatal alveolar bone width increased significantly from crest to apex in anterior and posterior regions.
• Average maxillary alveolar ridge widths ranged from 7.43 mm (central incisor) to 12.38 mm (first molar).
• Mandibular alveolar bone width did not consistently increase buccally, and apical regions were thinner than mid-root levels.

Conclusions:

• The study provides valuable clinical guidelines for determining dental implant diameter and position.
• Measurements are applicable to the production of prefabricated membranes and customized alveolar bone scaffolds.
