ABSTRACT
The alveolar bone quantity and quality assessment is crucial, both assessments could be used to ensure the success rate of dental implant treatment. In implant dentistry, assessment of the alveolar bone quantity and quality can be done through dental imaging. Recently, three-dimensional dental imaging popularly used as cone-beam computed tomography (CBCT). CBCT has several advantages that enable the assessment of alveolar bone. Our study aimed to assess the thickness and height of alveolar bone at maxillary and mandibulary at dental implant sites using CBCT. The recipient of dental implant sites was determined using the i-Dixel dental implant planning program. Totally ninety-three CBCT radiograph data were collected and recorded in Microsoft Excel. Our finding showed the mean of alveolar bone height and thickness were 5.7–17.1 mm, and 3–11.7 mm, respectively. Two observers evaluated the data and the inter-observer reliability score ranged from 0.842 to 0.949. T-test analysis showed statistically significant differences seen in the mandibular molar region for height assessment (p = 0.02) and thickness assessment the statistical significance was seen in the maxillary first incisor at crestal region with p = 0.04, mandibular premolar apical region with p = 0.01, and mandibular molar crestal region with p = 0.04. On the other hand, the one-way ANOVA test showed statistically significant differences only in the maxillary molar region with p = 0.01 for height assessment and no statistically significant differences were seen in thickness assessment. The older patient showed decreasing in the alveolar bone height and accurate measurement of the alveolar bone is critical for determining the size and length of the implant fixture.
