Clinical and radiographic analysis revealed a skeletal Class II malocclusion with molar and canine relationships also in Class II, moderate crowding in both arches, a deviation of the dental midline, and ectopic eruption of tooth 13. No functional issues with breathing or swallowing were observed, and oral health was generally good. A slight mandibular retrusion was noted in the soft tissue profile. A treatment plan was proposed using the Angel Aligner Pro system, aiming to correct dental misalignments and improve facial harmony through a minimally invasive, growth-adapted approach.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>[\/vc_column_text][vc_column_text css=&#8221;&#8221;]<strong><span style=\"color: #0094dc;\">Section<\/span><\/strong> Class II division 1 malocclusion<\/p>\n<p><strong><span style=\"color: #0094dc;\">Product<\/span><\/strong> Pro<\/p>\n<p><strong><span style=\"color: #0094dc;\">Malocclusion<\/span><\/strong> Skeletal Class II, Molar and Canine Class II<\/p>\n<p><strong><span style=\"color: #0094dc;\">Protocoles and features<\/span><\/strong> A8 Molar distalization[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=&#8221;.vc_custom_1744809826884{padding-top: 50px !important;padding-bottom: 50px !important;}&#8221;][vc_row][vc_column][vc_column_text css=&#8221;&#8221;]<\/p>\n<h3><span style=\"color: #0094dc;\">Initial Photos and datas<\/span><\/h3>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22569&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22580&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22591&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22602&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22613&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22624&#8243; img_size=&#8221;full&#8221; alignment=&#8221;center&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/6&#8243;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22635&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22646&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/6&#8243;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22679&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22668&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/6&#8243;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22657&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22690&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][\/vc_section][vc_section full_width=&#8221;stretch_row&#8221; css=&#8221;.vc_custom_1744721482175{margin-top: 25px !important;margin-bottom: 25px !important;padding-top: 50px !important;padding-bottom: 25px !important;background-color: #F5F5F5 !important;}&#8221;][vc_row][vc_column width=&#8221;1\/4&#8243;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h5><span style=\"color: #0094dc;\">Clinical examination and diagnosis<\/span><\/h5>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text css=&#8221;&#8221;]<\/p>\n<ul>\n<li class=\"p1\">Woman ; 12\/3 years<\/li>\n<li class=\"p1\">Skeletal Class II<\/li>\n<li class=\"p1\">Molar and canine Class II<\/li>\n<li class=\"p1\">Upper and lower dentoalveolar compression<\/li>\n<li class=\"p1\">Increased overjet and overbite<\/li>\n<li class=\"p1\">Upper midline deviated 0,5 mm to the right<\/li>\n<li class=\"p1\">Moderate upper and lower crowding<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/4&#8243;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h5><span style=\"color: #0094dc;\">Treatment plan<br \/>\n<\/span><\/h5>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text css=&#8221;&#8221;]We approached the case by combining upper distalization using the A8 protocol with an asymmetric virtual jump. In this way, we solved the crowding without proinclining the incisors and improved the anteroposterior relationship through the use of elastics. In the lower arch, we carry out a development of the posterior sectors prior to the resolution of the crowding, in order to avoid roundtripping and excessive IPR of the incisors. To achieve an effective extrusion and distalization of 13, we combine the use of direct bonding button on vestibular of 13, with angelButton elastics mesial and distal to the canine. These mechanics help to ensure that the extrusion is real and that the aligner always remains adapted.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/4&#8243;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h5><span style=\"color: #0094dc;\">Treatment details<\/span><\/h5>\n<p>[\/vc_column_text][\/vc_column][vc_column width=&#8221;3\/4&#8243;][vc_column_text css=&#8221;&#8221;]In the upper arch, the main goal will be to correct the Class II malocclusion by distalizing the upper posterior teeth in order to resolve crowding without proinclining the incisors. This movement will be accompanied by an asymmetric \u201cbite jump\u201d of 1 mm, which will help improve the skeletal Class II discrepancy, promoting mandibular projection, especially considering that the patient is still in the growth phase. Additionally, bilateral and symmetric expansion will be planned until a torque of 0\u00b0 is achieved, allowing for proper transverse alignment and greater stability of the final result. Lingual button cutouts will be placed on teeth 14 and 24 to facilitate the required movements. To optimize control and retention, vertical mesial beveled attachments, as large as possible, will be placed on the premolars and molars, as well as on teeth 12 and 22, reinforcing the mechanics in the anterior sector. The inclination of the central incisors 11 and 21 will be corrected according to the visual reference provided in the clinical image. Furthermore, it will be necessary to center the upper midline by shifting it 0.5 mm to the left to achieve greater aesthetic symmetry. As for the lower arch, treatment will begin with a phase of expansion and derotation of the posterior teeth, which will set the stage for subsequent movements in the anterior sector. Once this goal is achieved, alignment of the teeth from canine to canine will proceed, aiming to minimize anterior interproximal reduction (IPR) and avoid unnecessary round- tripping movements of the incisors. Vestibular button cutouts will be made on teeth 36 and 46, while teeth 37 and 47 will have horizontal attachments that will serve as anchorage to ensure stability during treatment.[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=&#8221;.vc_custom_1744809760250{padding-top: 50px !important;padding-bottom: 50px !important;}&#8221;][vc_row][vc_column][vc_column_text css=&#8221;&#8221;]<\/p>\n<h3><span style=\"color: #0094dc;\">Treatment setup<\/span><\/h3>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22701&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22712&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22723&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/6&#8243;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22734&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22745&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][\/vc_section][vc_section css=&#8221;.vc_custom_1744809769208{padding-top: 50px !important;padding-bottom: 50px !important;}&#8221;][vc_row][vc_column][vc_column_text css=&#8221;&#8221;]<\/p>\n<h3><span style=\"color: #0094dc;\">Treatment progress<\/span><\/h3>\n<p>[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22756&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22767&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22778&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22789&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22800&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22811&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/6&#8243;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22822&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22833&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/6&#8243;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22844&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22855&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/6&#8243;][\/vc_column][\/vc_row][vc_row][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22866&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22877&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][vc_column width=&#8221;1\/3&#8243;][vc_single_image image=&#8221;22888&#8243; img_size=&#8221;full&#8221; css=&#8221;&#8221;][\/vc_column][\/vc_row][\/vc_section][vc_section el_id=&#8221;CaseDownload&#8221;][vc_row][vc_column width=&#8221;1\/6&#8243;][\/vc_column][vc_column width=&#8221;2\/3&#8243;][vc_column_text css=&#8221;&#8221;]<\/p>\n<h4 style=\"text-align: center;\"><span style=\"color: #4192d6;\"><b>Download the full case to see the treatment results, the conclusion and get more details on the solution<\/b><\/span><\/h4>\n<p style=\"text-align: center;\"><strong>To download this report, you agree to subscribe to the Angel Aligner newsletter.
