Depends on the material they used.

Ususally they have dissolving rates as follows like the examples below:

Loss of 50% tensile strength in 14 days. 100% loss in 30 days.

Loss of 25-50% tensile strength in 30-45 days, complete loss in 90 days.

Loss of 25 % in one week, 50% in three weeks and complete loss of strength in 90 days.

It is SO varied and really depends upon which product (and which coating) your sutures are made from.

Do you know which sutures were used?
