Objective

The relevance of Class II interceptive therapy is controversial. The objective of this literature review was to note its indications and if a benefit is proven.

Materials and Methods

We carried out a systematic search on PubMed from 1999 to 2019 by keywords on randomized trials.

Results

Fourteen articles were selected, mainly grade B or C. The criteria evaluated were dental, skeletal, psychological, aesthetic, as well as cost, duration, incisor fractures, rate of stroke, complexity and treatment need. Overjet is an important criterion for the indication of interceptive treatment, but it is not the only one. The skeletal criterion, assessed mainly by the ANB, is only significant for three articles; the improvement of self-esteem is proven in one article and the interceptive treatment allows an aesthetic improvement (alignment of the maxillary incisors). The overall cost of treatment would be higher for two-step treatment. In only two articles, the authors wonder if the interceptive treatment facilitates future treatment. The rate of compensatory strokes and extractions are widely studied.

Discussion

The main criteria studied are ANB (controversial indicator), incisor fracture rate (trauma) and overjet.

Conclusion

Certain non-significant results must be put into perspective with the aim of the studies and the methods used.
