NCT03924726

Brief Summary

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).

Outcome Measures

Primary Outcomes (2)

  • 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

  • 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 Outcomes (1)

  • 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).

    9 months

Study Arms (3)

Control and experimental (4 weeks MOP)

OTHER

This is a split mouth study. At the experimental site in group 1, three Micro-osteoperforation (MOP) were made directly at the buccal cortical bone of extracted first premolars sites, at equidistance from the canine and second premolar under local anaesthesia. This group received four sessions of MOPs at an interval of 4 weeks.

Procedure: Micro-osteoperforation (MOP)

Control and experimental ( 8 weeks MOP)

OTHER

This is a split mouth study. This group received 2 sessions of Micro-osteoperforation (MOP) at an interval of 8 weeks.

Procedure: Micro-osteoperforation (MOP)

Control and experimental (12 weeks MOP)

OTHER

This is a split mouth study. This group received 2 sessions of Micro-osteoperforation (MOP) at an interval of 12 weeks.

Procedure: Micro-osteoperforation (MOP)

Interventions

Micro-osteoperforation technique is used to accelerate orthodontic tooth movement.
