[Technological aspects of agar-hydrocolloid impression materials].
Physical properties with clinical relevance has been tested on a number of agar hydrocolloid impression materials For 1 hour an almost perfect dimensional stability can be maintained when the impression is stored in water. Elasticity and strength are poor. Only the use of much bulk material may prevent damage during manipulation of the gel. The detail reproduceability meets all standards. A good compatibility with dental stone subsequently allows sharp details in the model.
