The human body is a system of interconnected systems. The inadequate functioning of one of these can have a significant impact on the development of defects and abnormalities in another area of the body. Defects in posture, caused by abnormalities in the alignment of the skeletal system, can result in asymmetries and deformities and misalignments in the mandibular and temporal joints, which are a direct cause of malocclusion and speech defects.
