List of metropolitan areas by population. One concept which measures the world's largest cities is that of the metropolitan area, which is based on the concept of a labor market area and is typically defined as an employment core (an area with a high density of available jobs) and the surrounding areas that have strong commuting ties to the core.
Average Costs. In treatment year 1, the average costs per patient diagnosed with PTSD ($8,300), TBI ($11,700), or both ($13,800) were much higher than the average costs for those with neither PTSD nor TBI ($2,400) (see Table 2 and Figure 3 on page 20).
Cost of treatment is very individual as every mouth is different. Cost will depend on treatment time, steps involved and will vary by location. An estimated cost range for âphase-oneâ treatment is $2,000 to $4,000. For âphase-twoâ treatment, an estimated cost range is $2,000 to $7,000. Clear aligner treatment costs more by about 20 to 50 percent. Orthodontic treatment can be a covered benefit through dental insurance.
