ABSTRACT

Introduction. Teeth malocclusion is a dental-facial anomaly which may arise anytime in life. Determining prevalence of malocclusion has been turned into a need by the Cuban population longevity growth process. Methods. Experimental study of 48 patients of both sex who were attended by the stomatology practice at Medical Surgical Research Center. They were offered a malocclusion diagnosis; besides, they were measured their bone density using multi-cut CAT. Patients were assigned randomly in two groups of 24 people each. Group A: those who were applied conventional rigid arch techniques (Roth and MBT). Group B: those who were implemented the straight arch technique “Synergy”. The total of patients, whose bone density was measured before and after, decreased to 15 patients; 6 of them to be applied conventional straight arch techniques and 9 of them to be applied the straight arch technique. The rest did not go through the study of final bone density. Results. The lack of differences regarding bone density between the maxillary and mandible before treatments that implemented conventional techniques and the low-friction technique, has proven that any of these techniques can be occasionally applied during malocclusion treatments. Conclusions. Low friction techniques highly influenced bone density in both maxillary and mandible; not being the same case of conventional techniques.
