Background: Dental implants have become an important option in the treatment plan in dentistry. Implant success is related to bone quality as well as bone density. Bone quality and quantity are typically estimated from radiographs before implant site preparation. A good preoperative assessment of bone density can guide the clinician regarding the implant type and the surgical technique to be used. Cone beam computed tomography (CBCT) can provide an accurate three dimensional high resolution images as well as a direct measurement of bone density expressed in Hounsfield units (HU), a value that offers crucial information about the bone quality, which is a major concern for implant success.

Aim of the Study: To assess the bone density in terms of Hounsfield units of different region of upper and lower jaw by Cone beam computed tomography for dental implant treatment planning.

Materials and Methods: This Cross Sectional Study was conducted with 20 patients having one or more missing tooth, who were selected from the outdoor clinic of Department of Prosthodontics or Department of Oral and Maxillofacial Surgery, BSMMU, Dhaka, Bangladesh and planned for dental implant treatment. After the clinical examination, CBCT images of the maxilla and mandible was obtained by the same operator according to the standardized procedure. Bone density in terms of Hounsfield unit (HU) was measured from anterior and posterior region of both jaws. All the information was recorded in a specifically designed data entry sheet. Data were processed and analyzed by SPSS version 22 (Armonk, NY, USA). Descriptive statistics, independent sample t-test and ANOVA with Post Hoc Tukey were used to analyze and compare the data. P-value less than 0.05 (p < 0.05) was considered statistically significant. The summarized data was presented as mean, standard deviation, percentages and ratio on table and diagram.

Results: In this present study, differences in the bone densities of the four regions in the mouth were significant, with the anterior mandible yielding a higher mean bone density value (1615.65 ± 203.64), followed by posterior mandible (1434.15 ± 222.65), anterior maxilla (1421.00 ± 202.85), and the posterior maxilla (1265.05 ± 120.80). However, when considering all four regions in male and female participants, the mean bone density in female was (1494.84 ± 230.12 HU), which was higher than male (1393.37 ± 215.56 HU). The results of this study also indicated a strong correlation between the four regions of the jaw and the bone density. The mean bone density value from anterior and posterior regions of both jaws were higher than previously reported studies. In this present study, only D1 and D2 types of bone were found in the four different areas of jaws.

Conclusion: The study conclude that, the anterior mandible has the highest jaw bone density followed by posterior mandible, anterior maxilla, and the lowest jaw bone density in the posterior maxilla. It is suggested that a CBCT investigation can provide valuable information of bone density to the clinicians prior to installation of the dental implants.
