Clinically relevant properties of 3M ESPE Polyethers, Initial hydrophilicity (part one)

The exact reproduction of the intra-oral situation is the most important pre-requisite for a perfect fit of prosthetic work. State of the art precision impression materials are capable to reproduce the intraoral situation quite well. However, in difficult clinical situations especially if saliva and/or blood is present, many of the commercial impression materials do not show the same performance than they would under ideal conditions. The result might be insufficient precision and detail reproduction especially in critical areas such as the margins. Polyether impression materials manufactured by 3M ESPE are well known for their very high reliability in all clinical situations. Mainly in moist environment – and there is always moisture present in the oral cavity – polyethers from 3M ESPE convince the dental practitioner as well as the specialist by their compelling results. Therefore, this particular class of impression materials is often refered to as forgiving. 3M ESPE has more than 40 years of experience in polyether development. The exceptionally high reliability of these materials has been proven over several millions of impressions that were taken with great success since their introduction to the marketplace in 1965. The very high degree of accuracy and detail reproduction has set the standard – a fact that is well respected in the dental community.
