Introduction: Currently, there is limited evidence on the changes in skeletal, dental and soft
tissue in retraction of anterior maxillary teeth by extraction and mini-implant assisted
distalization. In this review, we examined the evidence from Randomized and nonrandomized controlled clinical trials, clinical trials (prospective studies), to provide
information on any association between extraction and mini-implant assisted distalization on
retraction of anterior maxillary teeth. Method: We conducted a comprehensive electronic
search up to October 30, 2020, in the following databases: PubMed, Embase, Cochrane
Database of Systematic Reviews, Cochrane Central Register of Controlled Trial. The
eligibility criteria (PICO) were used to determine eligible reports for this systematic review.
Data was extracted by two reviewers on the basis of year of publication, study design,
materials, method measurements, age, sample size, treatment period, force applied, amount of
retraction of anterior teeth, amount of skeletal changes obtained, and improvement of facial
morphology gained, side effects, and author’s conclusions, among others. The meta-analysis
was performed for both quality and quantity of the information retrieved from the finally selected studies which justified a meaningful statistical combination. Result: The most
important distalization effects (6.4 mm) were achieved by using the mini-screw supported
pendulum appliance. The shortest linear distalization (1.8 mm) measurements were reported
with one miniscrew within the inter-radicular area between which teeth? Conclusion: To take
advantage of the full retraction capacity, additional distalization modalities may be beneficial
in the maxillary arch. Four premolar extraction treatment may be recommended when greater
improvement of incisor retraction and soft-tissue profile is required in adult patients with
Class II malocclusion. Implications for study as the quality of proof ranged between low to
moderate in terms of the skeletal and soft-tissue variables and very low to moderate in terms
of the dental variables, therefore, we approve the need for more well-conducted RCTs in the
en masse retraction field.
