Abstract EN
Introduction: The achievement of esthetic and Functional optimum of dentofacial complex requires correcting discrepancies of jaws relationship; class-II is the most common malocclusion worldwide and mostly related to a retrognathic mandible.
Objective: The Objective of this study was to compare mandibular changes produced by a new technique (elastic forces based on skeletal anchorage mini-plates) with changes produced by conventional class-II elastic forces.
Methods: The study sample consisted of 30 patients with skeletal class-II malocclusion caused by retro-gnathic mandible with a mean age (11.5±0.5 years).
They were randomly divided into 2 equal groups: the first group included 15 patients (6 males, 9 females) treated by elastic forces based on skeletal anchorage mini-plates.
The second group included 15 patients (7 males, 8 females) treated by conventional class-II elastic forces.
Lateral cephalographs were taken immediately before and after skeletal treatment.
Eleven linear and angular measurements related to the mandible were determined in each cephalograph pairs.
Dependent and independent t-tests were performed to evaluate the difference within each group and between the two groups respectively.
Results: Both techniques were effective in producing mandibular changes.
However, the mandibular changes produced by elastic forces based on skeletal anchorage mini-plates (namely SNB, Co-Go, ArGo, N-Pog and Lie-Lia: Go-Me) were significantly better compared to that produced by the conventional class-II elastic forces.
Conclusions: Both techniques treat the mandibular retrognathism.
The mandibular changes induced by elastic forces based on skeletal anchorage mini-plates are purely skeletal while some those induced by conventional class-II elastic forces are dento-alveolar.
