With a low vertical profile of 2.1 mm and diameter of 4.4 mm, the OT Equator is the smallest attachment system on the market. This system offers multiple solutions for overdenture treatment planning when vertical space limitations are a consideration.

Available in two versions, castable and prefabricated titanium abutments which are compatible with any implant brand on the market and manufactured with cuff heights from .5 mm to 7 mm. Female caps are retained by means of a stainless steel housing ranging in four levels of retention, making it easy to process at the dental laboratory or chair side in the dental office.

The unique design and exceptionally low 2.1 mm profile of the OT Equator 4 in 1 System provides exceptional stability and superior retention when compared with other attachment systems. Due to it's lower radius, OT Equator is indicated to correct divergence up to 28 degrees between implants without affecting the functionality of the nylon cap. A complete line of OT Equator accessories and tools are also available.

ATTENTION: Where implant divergence exceed the maximum 28 degrees, Sphero Block and Sphero Flex are recommended case plan options.
