The periodontal aspects of orthodontic treatment are reviewed in this article highlighting the cases of maxillary expansion, molar extrusion, and class III malocclusions. Gingival recession is dependent on two main factors namely, gingival biotype and the bone morphology. Teeth when placed in the center of the alveolar ridge and having adequate bone support circumferentially and alveolar bone on the labial and lingual aspects of the roots are considered to the best for supporting the teeth. The arch width can be increased with expansion appliances such as RPE which may lead to undesired effects on the periodontium. In this article, we review how mini-screws can be used for expansion in posterior crossbite and protraction of maxillary arch in class III malocclusions to prevent periodontal issues.
