Abstract
Fatigue results show that bone of TTI model exhibit the maximum number of fatigue life cycles whereas bone of TTX model has the lowest number of cycles and bone of TTC models has intermediate number between TTI and TTX. This result predict longer life of bone before failure (resorption) using TTI implant followed by TTC and TTX respectively.
Many health educators calculate the average numbers of bite in adult person to be 10-100 bites. On the other hand , when normal person chew, he need about 32 strokes to break down this bite and swallow it whereas in complete denture patients number of strokes per bite increase to reach 69 one. Fortunately, construction of overdenture supported by implants make patient need only 40 strokes to deal with one bite which is a great advantage.
Using the previous data we could calculate the numbers of chewing cycles per day to be 50 × 40 = 2000. If we theoretically calculate life time of models we will subdivide number of life cycles by average number of chewing cycles per day.
