Could malocclusion cause by ENVIRONMENTAL Factors? ------------------------------- orthotropics.co.uk ------------------------------- 1/ Muscle Tone and Activity. Modern diets are relatively soft and it has been suggested that this has lead to a reduction in muscle strength (Kiliaridis and Kalebo 1991). Look back at Figure I/4 which showed a 12-year-old girl who suffered from muscular dystrophy, compared with the average profile for her age. Her maxilla appears to have collapsed downwards, possibly under the force of gravity and drag from the ‘Soft Tissue Mask’ (Solow and Kreiborg 1977) to create a horrendous skeletal malocclusion. 2/ Open-Mouth Postures. The term ‘Mouth breather’ can be misleading because Vig and his co-workers (1981) showed that many individuals who keep their mouths open, continue to breathe nasally.
