nerves. One of the other joints used on the rock wall is the temporomandibular joint otherwise known as the jaw joint. The jaw joint accounts for the hinge like movement of the mandible. To parts of the jaw joint collaborate to move the jaw. The first part the inferior compartment permits the condyler process of the mandible to rotate which causes the opening and closing of the mouth. The second part the superior compartment lets the condylar process move forward where it rests against the articular

It is thought that the technique used to harvest grafts affects the number‚ activity‚ and viability of transplanted bone tissue. Experiments conducted on pig mandibles compared bone milling‚ bone drilling‚ bone scraping‚ and piezo surgery techniques. The results showed that cell viability and growth factor expression of bone morphogenetic proteins and vascular endothelial growth factors were higher in the bone

Lower third molars or wisdom teeth normally have their occlusal surfaces tilted slightly forwards and lingually during early calcification.

Strokes and Bell’s Palsy present symptoms that are fairly close to each other. Lyme disease and diabetes could also cause the numbness and the paralysis in the case of lyme disease. Unilateral facial paralysis and/or droop is exhibited in Bell’s Palsy and a stroke‚ as well as speech difficulty. An inability to furrow eyebrows and a loss of the nasolabial crease are mainly attributed to Bell’s Palsy‚ unlikely to occur with a stroke (Mayhew).
