Which statement is not true regarding an automix impression system?

The statement that "The unit can be used with light-bodied material only" is not true regarding an automix impression system. An automix impression system is designed to accommodate various types of impression materials, not just light-bodied ones. This versatility includes the ability to mix and dispense both putty and light-bodied materials, allowing dental professionals to choose the appropriate consistency for their specific clinical needs.

The automix systems are particularly beneficial as they offer convenience and consistency in mixing, ensuring that the materials are accurately dispensed in the correct ratios, which is critical for achieving optimal impressions. This means that dental practitioners can utilize the system for a broader range of applications beyond just light-bodied materials, making it a versatile tool in dental procedures.
