This study aimed to assess hard and soft tissue shape variations and changes following orthodontic treatment in Class III skeletal malocclusion using GMA. Methods: A retrospective study was conducted on 84 lateral cephalometric radiographs (pre-treatment and near-end treatment) of Class III patients aged 16\u201340 years (ANB &lt; 2\u00b0). Thirty-five landmarks were digitized in Cartesian coordinates using MorphoJ software for shape analysis. Results: The sample included 62% females and 38% males, with a mean age of 24.7 \u00b1 5.2 years. Vertical dimension variations (hypodivergent to hyperdivergent) contributed most to shape changes PC1 (23.35%), followed by anteroposterior variations PC2 (13.51%). Gender significantly influenced hard and soft tissue variation with 30.91%SS (F = 56.99, p &lt; 0.0001). Males had significantly larger and longer ramus, body of the mandible, alveolar height, LAFH, TAFH and upper lip length. (PD: 0.026, p &lt; 0.05). Significant shape changes were seen in the mandible (PD = 0.018, p &lt; 0.05). SNB increased by 0.41\u00b0 (from 81.73\u00b0 \u00b1 3.67\u00b0), and ANB improved by 0.46\u00b0 but remained Class III (\u22120.33\u00b0 \u00b1 1.82\u00b0). Lower anterior facial height increased by 1.78 mm (p &lt; 0.05). The lower incisors retroclined significantly (from 92\u00b0 \u00b1 8.56\u00b0 to 87\u00b0 \u00b1 6.96\u00b0, p &lt; 0.05), while the interincisal angle increased by 5.9\u00b0. Upper incisors remained procline (118\u00b0 \u00b1 11\u00b0, p &gt; 0.05). Upper lip length increased by 0.4 mm (p &lt; 0.05). Conclusions: Vertical and anteroposterior shape variations are notable within Class III malocclusion. Post-treatment changes in both hard and soft tissues indicate that orthodontic camouflage can enhance facial esthetics and skeletal balance. GMA provides objective quantification and visualization of these treatment-related craniofacial changes.<\/jats:p>","DOI":"10.3390\/jcm15020639","type":"journal-article","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T15:52:57Z","timestamp":1768319577000},"page":"639","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Geometric Morphometric Analysis of Hard and Soft Tissue in Class III Malocclusion Before and Near-End Orthodontic Treatment"],"prefix":"10.3390","volume":"15","author":[{"given":"Albert","family":"Koay Quan Hong","sequence":"first","affiliation":[{"name":"Department of Family Oral Health, Faculty of Dentistry, Universiti Kebangsaan Malaysia, Jalan Raja Muda Abdul Aziz, Kuala Lumpur 50300, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neo","family":"Joe","sequence":"additional","affiliation":[{"name":"Department of Family Oral Health, Faculty of Dentistry, Universiti Kebangsaan Malaysia, Jalan Raja Muda Abdul Aziz, Kuala Lumpur 50300, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3225-8327","authenticated-orcid":false,"given":"Helmi","family":"Mohd Hadi Pritam","sequence":"additional","affiliation":[{"name":"School of Health Sciences, USM Health Campus, Kelantan 16150, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2308-365X","authenticated-orcid":false,"given":"Khairil Aznan","family":"Mohamed Khan","sequence":"additional","affiliation":[{"name":"Department of Family Oral Health, Faculty of Dentistry, Universiti Kebangsaan Malaysia, Jalan Raja Muda Abdul Aziz, Kuala Lumpur 50300, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7343-0800","authenticated-orcid":false,"given":"Rama Krsna","family":"Rajandram","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Universiti Kebangsaan Malaysia, Jalan Raja Muda Abdul Aziz, Kuala Lumpur 50300, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3394-369X","authenticated-orcid":false,"given":"Murshida","family":"Marizan Nor","sequence":"additional","affiliation":[{"name":"Department of Family Oral Health, Faculty of Dentistry, Universiti Kebangsaan Malaysia, Jalan Raja Muda Abdul Aziz, Kuala Lumpur 50300, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.9734\/JAMMR\/2018\/39927","article-title":"An Overview of Class III Malocclusion (Prevalence, Etiology and Management)","volume":"25","author":"Jaradat","year":"2018","journal-title":"J.
