Introduction:
A close relationship occurs between the type of bone density and the success of orthodontic mini-implant. The aim of this study was to find out the mean bone density in interradicular areas of the maxilla among patients visiting dental unit of a tertiary care centre.
Methods:
A descriptive cross-sectional study was performed at the Department of Orthodontics and Dentofacial Orthopedics at a tertiary care centre from 15 January 2022 to 28 June 2022 after taking ethical approval from the Institutional Review Committee (Reference number: UCMS/IRC/175/21). Data was collected from scan reports obtained with a computed tomography scanner. Bone density was measured at 6 mm height from the alveolar crest. Convenience sampling was done. Point estimate and 95% Confidence Interval were calculated.
Results:
Out of 70 patients, mean bone density at interradicular areas of maxilla was 992.31±204.20 HU (944.46-1040.13, 95% Confidence Interval). Between central and lateral incisor 50 (71.44%) had D2 type of bone density.
Conclusions:
The mean bone density in inter radicular areas of the maxilla among patients visiting the dental outpatient department was similar to other studies done in similar settings.
Keywords:
bone density; prevalence; prostheses and implants.

01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:27Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
01:17Gross Anatomy of Bone
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...
