Aim and Objectives: The main objective of this study was to evaluate how much crushed, extracted human teeth material can use to fill an empty alveolus of the mandibular anterior teeth. Material and Methods: Fifty-four human teeth were collected from 10 donors due to advanced periodontal disease. The patients were clinically selected, signed informed consent, and receive no financial compensation for participating in this study. Fifty-four teeth were mechanically cleaned, dried, sectioned, and grounded. All teeth are grounded using the Smart Dentin Grinder machine. Cone-beam computed tomography scanners of each patient were done and processed the standard tessellation language images by a three-dimensional (3D) printer, and 3D models were obtained. Results: The mean of each alveolus was 12.1 ± 0.34 mm for lower incisors and 17 ± 0.29 mm for lower canines. The mean values of root material we need for central and lateral incisors alveolus filling were 0.298 ± 0.14 cc, and for lower canines was 1.02 cc. Therefore, we need one root or one and half-crowns must be needed to fill a lower incisor alveolus. A lower canine needs at least one canine root or one canine crown and two lower incisors crown to fill the canine alveoli. Conclusions: Dentin is a helpful graft to fulfill an empty alveolus due to osteoinductive properties, and a ground crown is useful for buccal bone protection due to osteoconductive properties before and after implant placement.
