Twenty--five coping were divided into five groups according to frequency of recast, And I n ied to cast Eve times without adding new metal.
The experimental results wen- ;is follows:
1. To cast 13 times was showed good fitness on each cervical margins, but the fitness was decreased as to ncreased reuse.
2. I got bad fitness casting bodies to 5 times.
3. The mesio and disto cervical i-targrin were appeared bad adaptation than the bucco and linguo cervical rnarglilt.
4. Although to cast four times ,,l´s gotten good fitness on some cervical margins, Three casting body were appeared inaccurate fitness on mesio, disto cervical margin. And I could not got good casting bodies without adding new metal.
