RESUMEN
To present a contemporary method of aligning horizontally impacted teeth. A medically fit 17 year old female patient, presented to the orthodontic clinic with a horizontally impacted lower left second molar in an otherwise Class I occlusion with no aesthetic concerns. A two year history of the lower left third molar extraction in an attempt to normalize the lower left second molar's path of eruption was reported by the patient with no evident success. The patient was treated with a sectional fixed appliance on the lower left quadrant supported by a mini-implant temporary anchorage device in the left maxillary tuberosity region for inter-maxillary elastic wear. Successful alignment of the lower left second molar was achieved in a period of eleven months. The incorporation of mini-implants into orthodontic mechanics, has provided new limits to contemporary orthodontics, enabling orthodontists to align teeth that were previously considered common extraction candidates
RESUMEN
This case report describes a 14 year old female patient, with pseudo-Class III incisor relationship on a mild Class III skeletal base with ankyloglossia. It highlights the relationship of an unfavorable soft tissue environment exerted by "tongue tie" and genetic factors proposed by the presence of family history in the development of a Class III malocclusion. Orthodontic treatment was provided on, a non-extraction basis to correct the Class III relationship. The patient was then referred for labial and lingual frenectomy using laser surgery to stabilize the achieved correction and facilitate the wear of orthodontic retainers by the patient. The first annual review carried out at the age of 17 years has revealed stable results
