A 33-year-old woman had a chief complaint of difficulty chewing, caused by a constricted mandibular arch and a unilateral full buccal crossbite (scissors-bite or Brodie bite). She requested minimally invasive treatment but agreed to anchorage with extra-alveolar temporary anchorage devices as needed. Her facial form was convex with protrusive but competent lips. Skeletally, the maxilla was protrusive (SNA, 86°) with an ANB angle of 5°. Amounts of crowding were 5 mm in the mandibular arch and 3 mm in the maxillary arch...

The clinical examination of an 11.10-year-old girl in permanent dentition showed severe crowding, chewing problems and her right maxillary lateral incisor was in palatal position. The molars were in Class II relationship on both sides. An extraction treatment was planned. Upper second premolars and lower first premolars were extracted. Lower crowding was eliminated using physiological tooth movement called "driftodontics". Slots sized 0.022 inches and self-ligating brackets were used. The patient also used a high-pull headgear for anchorage and vertical control reasons for a short period...

Treatments without tooth extractions have become more popular over the last two decades. In this context, expansion of the maxillary arch is an interesting treatment option for cases in which space is required and other factors not favoring extractions (such as the facial profile) are present. According to several authors, this posterior expansion can be obtained using a system comprising self-ligating brackets and superelastic nickel-titanium arches. The present article aims to report a case of a young patient with Class II, Division 2 malocclusion, with impacted upper canines and significant arch length-tooth discrepancy...
