Musculature of the jaw The masticatory muscle (M. masseter) is divided into two parts. One part is more superficial, sloping backwards and downwards (pars superficialis), one part is deeper and vertical (pars profundus), both parts originate at the zygomatic arch (Arcus zygomaticus) and are attached to the outer surface of the mandibular frame (ramus mandibulae). … Musculature of the jaw | Pine

Tooth replacement (permanent dention) After the milk teeth have fully matured from the age of 6-7 years, a change of teeth follows in humans between the ages of 6 and 14 years. This change of teeth is usually only completed between the 17th and 30th year of life by the eruption of the wisdom teeth. … Tooth replacement (permanent dention) | Milk teeth

Small but deep indentations within the jawbone (lat. alveoli) contain … Tooth strip and periodontal apparatus | Upper jaw

The fracture of the upper jaw usually shows typical courses (fracture lines) that correspond to the weak points … Diseases of the upper jaw | Upper jaw
In humans, the first attachment of the teeth takes place in the form of milk teeth. For reasons of space this contains only 20 milk teeth. As the jaw grows, it is gradually replaced. The teeth are then changed. The teeth are placed as so-called diphydontia – double dentition. It is therefore distinguished between two … Milk tooth
Toothing Due to the longitudinal growth of the root, the pressure against the jawbone finally causes the milk tooth to erupt. This is called first dentition. Usually the eruption of all 20 milk teeth is completed by the 30th month of life. They are fully developed by the third year of life, while the roots … Toothing | Milk tooth
