For Implants

With a low vertical profile of 2.1 mm and a 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 stainless steel housing ranging in four levels of retention, making it easy to process at the dental laboratory or chairside 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 its 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 exceeds the maximum 28 degrees, Sphero Block and Sphero Flex are recommended case plan options.

 

This newly innovative interior design of the OT Equator standard stainless-steel housing offers multiple clinical advantages for a low-profile passive path of insertion when divergent or flared implants are presented.


The Equator Smart Box is engineered with a rotating Titanium inner liner providing a durable metal-to-metal core. Once activated, the system allows up to 50 degrees angulation correction between two implants, without loss of retention.


This is achieved thanks to the system's highly elastic assortment of color-coded female retentive caps. Smart Box Housings can be purchased individually and are available in a Smart Box cap assortment kit.

For Threaded Equator

The titanium nitrate finish gives the attachment a smooth 1600 Vickers hardness, extending the life expectancy of the male and elastic female components.

With Threaded Sleeve

The low profile OT Equator attachment for bar connections is manufactured with a 1.6 mm thread, 2 sided titanium bonding sleeve, and a base spacer. This new system offers laboratories two cost effective options for placing the attachment on CAD/CAM milled or cast bar overdenture connections. The OT Equator is the smallest attachment in it's classification. Dimensions are 2.1 mm high and 4.4 mm wide with cap in place.Technicians can select between screwing the threaded OT Equator directly into a milled site, or use the base spacer and bonding sleeve with traditional casting techniques which eliminates the need for drilling and tapping. Once the bar is cast, the OT Equator and sleeve are screwed together and bonded directly into the attachment location.

 

The OT Equator kit comes complete with 2 titanium nitrate coated attachments, 2 titanium bonding sleeves, 2 base spacers, an assortment of caps and 2 stainless steel housings.
