40 years at the chair. Then I made my own.
I tested every retractor on the market. Some flexed in the cheek. Others rusted after fifty cycles. The wide ones got in the way of the lens. The narrow ones didn't pull enough tissue to see the distal of the second molar.
So I designed the shape I actually wanted — wire-frame for an unobstructed view of the dentition, contoured to the cheek, in a grade of steel that survives a serious workload. Designed in Switzerland. Manufactured by Zasber International to my specifications. Registered under EU MDR. Shipping from Bülach since 2023.
