Objectives: The aim of this study is to evaluate the role of multi-detector computed tomography of 
jaw bones through measurement of jaw density in patients submitted to dental implant restoration .
Patients and methods: Our study included 30 systemically healthy patients with partially edentulous 
areas planning for dental implantation, 20 females and 10 males, ranged in age from 21-65 years with 
mean age of ±45 years. All patients were referred from the Out-Patient Clinic, Oral Medicine and 
Periodontology Department, Faculty of Dental Medicine, Al-Azhar University, Assiut Branch , during 
the period from February 2018 to October 2018. Results: Our study included 30 cases and our results 
shows that 9 cases are suitable for implantation (D1, D2) (30%), 15 cases are relatively suitable for 
implantation (D3) (50%) and 6 cases are not suitable for implantation (D4) (20%). Conclusion:
Applying the findings of the current study, it is concluded that dental MDCT is considered an 
excellent noninvasive imaging modality in the preoperative evaluation of dental implant patients 
through measurement of jaw bone density .
