Introduction
The study aimed to investigate the effects of micro-osteoperforations (MOPs) on the changes
in mandibular bone volume fraction (Bone Volume/Total Volume, BV/TV), in relation to the MOP
effects on the rate of orthodontic tooth movement, using CBCT images. The other objective was
to evaluate the effects of different frequency intervals (4 weeks, 8 weeks and 12 weeks) of
MOPs on mandibular bone volume fraction (BV/TV), in relation to the rate of tooth movement.
Methods
In 24 participants, orthodontic force of 140-200 grams was applied for mandibular canine
retraction. Three micro-osteoperforations (MOP's) were made according to the scheduled
intervals of the three different groups (4, 8 and 12 weeks) directly at the mandibular buccal
cortical bone of extracted first premolars sites. At the 12th week following MOP application,
CBCT scans were performed. CT Analyser software was used to compute trabecular alveolar bone
volume fraction (BV/TV).

Primary | To investigate the effects of micro-osteoperforations (MOPs) on mandibular bone volume fraction (BV/TV). | BV/TV ratio was assessed between control and intervention sides to assess the effects of micro-osteoperforations (MOPs) on the changes in mandibular bone volume fraction (Bone Volume/Total Volume, BV/TV ). | 9 months | |
Primary | To investigate the effects of micro-osteoperforations (MOPs) on the rate of orthodontic tooth movement. | The effect of MOPs on the rate of canine tooth movement was assessed by comparing the distance of canine retraction between control and micro-osteoperforations sides. | 3 months | |
Secondary | The other objective was to evaluate the effects of different frequency intervals (4 weeks, 8 weeks and 12 weeks) of MOPs on mandibular bone volume fraction (BV/TV). | Bone volume fraction (BV/TV) was assessed by comparing the available space between control and MOP sites in three different interval groups. | 9 months |
