This became known as Chargaff's ratio, and it was an important clue for solving the structure of DNA. Downloads. Downloads.
The average annual overhead for a dental office (not including the dentistâs salary) is $350,000. The average clinician works 33 hours per week for 48 weeks, which is 1,600 hours per year. By taking the $525,000 average annual revenue and dividing it by 1,600 hours, we get $312 an hour to keep the office operating profitably.
How it Works. As with a traditional dental insurance plan, a direct reimbursement dental insurance plan usually has a maximum yearly allowance. This means that the plan will only pay for a certain amount of dental work each year. The average yearly allowance for any type of dental plan is around $1,000 to 1,500. A common direct reimbursement plan would pay for 100% of the first $100 spent on dental services; 80% of the next $500; and 50% of the next $1,000.
