Miniscrew implants demonstrated an 87.7% success rate when used for anchorage reinforcement, according to a recent study conducted by Greek researchers. The findings appear in the Journal of Dental Research.
For the study, the researchers conducted literature searches with specific inclusion and exclusion criteria. Of the 3,183 original papers, eight met the inclusion criteria.
The researchers found that when miniscrew implants and conventional anchorage groups were compared, the miniscrew implants significantly decreased or even negated loss of anchorage, with a mean difference of 2.4 mm (p=0).
They also noted that anchorage loss occurred less frequently when the miniscrew implants were placed between the second premolar and the first molar; when the patient had two miniscrew implants inserted in his or her jaw; when they were connected directly; and when the treatment extended beyond 12 months.
Due to the number, quality, and heterogeneity of the included studies, however, the researchers warn that their findings should be interpreted with caution.
