Healthcare systems in Europe struggle with inadequate co-ordination of care for people with chronic conditions. Moreover, there is a considerable evidence gap in the treatment of chronic conditions, lack of self-management, variation in quality of care, lack of preventive care, increasing costs for chronic care, and inefficient use of resources. In order to(More)
The percentage of dry weight distribution of the jaw muscles is described, and muscle growth is calculated by means of second degree homogeneous linear differential equations with constant coefficients. The components of the chewing muscles are calculated from the parallelogram of forces on the basis of their dry weights. Changes in the shape of the skull(More)
The masseter muscle is the most powerfully developed of the jaw muscles in the miniature pig MINI-LEWE. Its internal skeleton contains 5 Sehnenspiegel. The zygomatico-mandibular muscle acts as a link between the masseter and temporal muscles. The pinnate structure of the temporal muscle results from the internal tendons, which attach to the coronoid(More)
The basic pinnate structures caused by Sehnenspiegel in the jaw muscles are already present in newborn animals. The functional changes in the jaw muscles are described in terms of an analysis of force components based on the dry weights of the individual muscles involved in chewing action. Although the protractive and retractive components are relatively(More)
The changes of the skull, which we can observe during the anthropogenesis, are reflected especially in the different skull proportions. We carried out metric measurements at the median level on 10 adult skulls each of humans, chimpanzees and gorillas as well as 11 skulls of orangutans. All skulls were scanned with a CT at the median level. We measured the(More)
The graphs showing the dimensions and angles of the skull and jaw indicate that postnatal development trends are basically uniform. Comparison with the Vietnamese miniature pig shows that the miniature pig MINI-LEWE has a longer skull. Postnatal skull growth is accompanied by a distinct shift in proportions. The sequence of dentition if broadly identical to(More)
Skull and jaw growth are described mathematically as a dynamic process. Graphs of the growth process show that basically the rate of growth decreases monotonically with increasing age. The maximum rate of growth was recorded at the time of eruption of the deciduous dentition during the first 4 months of life. As expected, the changes in the measured angles(More)
The postnatal changes in the structures of the masticatory muscles are explained on the basis of the Sehnenspiegel. The jaw musculature of juvenile miniature pigs is similar in structure to that of adult animals. All Sehnenspiegel can be found in animals that are only 3 d old. Postnatal development of the masticatory musculature takes place on the basis of(More)
