1. A method for impression-taking in immediate loading technique in a patient's mouth that contains an open wound, comprising the steps of:
i) providing a radiopaque and aseptic material comprising a first component A and a second component B; said components A and B are selected from the group consisting of diorganopolysiloxane polymers having the following formula (I):
CH2═CH—(—SiR1R2O)m—SiR1R2CH═CH2  (I)
where R1 and R2 are an un-substituted monovalent hydrocarbon radical; the integer m is such that the viscosity of the polymer at 23° C. is comprised from 50 cP to 1,000,000 cP, wherein said material further comprises an insoluble radio-opacifying filler,
ii) applying said material to a site in the patient's mouth and forming an impression of said mouth with said material,
iii) removing said impression containing material from said mouth; and
iv) inspecting the patient's mouth for any residual said radiopaque material to be removed,
wherein the step of inspecting comprises use of radiography about 10 days after said removing step.
