EFFECTIVENESS OF MICRO-OSTEOPERFORATIONS IN ACCELERATING ALIGNMENT OF
MAXILLARY ANTERIOR CROWDING IN ADULTS: A RANDOMIZED CONTROLLED CLINICAL
TRIAL

Shahrin AA, Ghani SH, Norman NH
Objectives: To investigate the effectiveness of micro-osteoperforations (MOPs) in overall
time taken for alignment of maxillary anterior crowding and to evaluate the alignment
improvement percentage within 6 months between MOPs and control groups. Materials
and methods: Thirty adult participants (25 females and 5 males; mean age, 22.66 ± 3.27
years) with moderate upper labial segment crowding were randomly assigned into
intervention and control groups using block randomization. All participants had first
premolar extractions, bonded conventional fixed appliances, and 0.014-in, followed by
0.018-in nickel-titanium archwire placement for initial alignment. The intervention group
received a 3-mm deep MOPs procedure under local anaesthesia using a Propel device
(Propel Ortho Singapore, Pte, Ltd, Winstedt Rd, Singapore) on the labial attached gingivae
of maxillary incisors at monthly visits until complete alignment. Little's irregularity index
was used to assess the overall changes and measure the change of tooth alignment of the
6 maxillary anterior teeth. Assessor blinding was employed. Results: There was no
statistically significant difference in the median overall alignment duration between MOPs
and control groups (139 days [95% confidence interval, 115.32-161.83] vs 143 days [95%
confidence interval, 107.12-179.74]; hazard ratio, 0.829; P 5 0.467). The MOPs procedure
had no significant effect on the alignment duration (P 5 0.657) and no overall significant
difference in alignment improvement percentage among 2 groups on the basis of time (F
5 2.53; P 5 0.124). No harm was encountered. Conclusions: The application of MOPs is no
more effective in accelerating initial orthodontic alignment than conventional treatment.
