Abstract EN
Background : bone density is a very important factor in the successful plan of implant treatment.
The aim of the study is to evaluate the trabecular bone density of potential dental implant sites in different region of the jawbone by using Computerized Tomography (CT), and the relationship between bone density and insertion torque.
Materials and method : in this clinical study 64 patients were treated with 120 Xive FRIADENT DENTPLY system implants.
The implant recipient sites were divided in two groups according to gender ; 60 in males and 60 in females and each group was divided into subgroups according jaw (maxilla and mandible) and region (anterior and posterior).
The bone density of each implant recipient site was recorded in Hounsfield units (HU) using CT.
The maximum insertion torque (Ncm) values were recorded with torque controlling motor.
Results : there was a significant correlation between bone density and insertion torque in males (r = 0.
983, p < 0.001) and females (r = 0.955, p < 0.001).The trabecular bone density values were (682 ± 98 HU, 481 ± 104 HU, 413 ± 92 HU, and 263 ± 67 HU) values in the anterior mandible, posterior mandible, anterior maxilla, and posterior maxilla, respectively.
Trabecular bone density was higher in males in comparison to females and the bone quality was higher for the mandible than for the maxilla, and higher for the anterior region than for the posterior region of these bones.
In females there is no significant difference in bone density (p < 0.05) between the posterior mandible and anterior maxilla and between males and females at posterior maxilla (p < 0.001) Conclusion : trabecular bone density is a key determinant for clinical success ; CT is a useful tool for assessing the bone density.
