mandibular dentition using various temporary skel-etal anchorage devices (TSADs).6,9,10,14-20 TSADs are more reliable and efficient than conventional methods because they allow for total distalization of the mandibular dentition while reducing some of the negative effects and need for patient cooper-ation.

Affected people typically have delayed growth (often seen in utero, before birth). We evaluated change in the mandibular condyle after orthognathic surgery using cone-beam computed tomography (CBCT) in patients with facial asymmetry. It is frequently used by dentists, orthodontists, and oral and maxillofacial surgeons as a treatment planning tool. Torus mandibularis is a bony growth in the mandible along the surface nearest to the tongue.Mandibular tori are usually present near the premolars and above the location of the mylohyoid muscle's attachment to the mandible. just before eruption of the second permanent molars. just after eruption of the second permanent molars.
