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.

​With its 2.1 mm vertical height and 4.4 mm width the new OT Equator from Rhein83 USA offers the lowest profile and least overall dimensions of any overdenture bar attachment system on the market. Manufactured with a standard 2 mm threaded base, the OT Equator is indicated for CAD/CAM milled bars or in lab tap and thread applications. The titanium nitrate finish gives the attachment a smooth 1600 Vickers hardness, extending the life expectancy of the male and elastic female components.

 

Nylon caps are available in 4 levels of retention and easily maintained by the dental office. 

Black processing caps, stainless steel housings, impression copings, laboratory analogs and tools are also available.

 

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.

 

Castable

Rhein83USA introduces OT Equator, the newest line of low profile castable, and direct implant overdenture attachments. With a low vertical profile of 2.1 mm and a diameter of 4.4 mm, 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 chairside in the dental office. A complete line of OT Equator accessories and tools are also available.

 

The OT Equator Pivot is a low-profile attachment that allows its usage even in the presence of little space. Made with Titanium with TiN treatment that increases the hardness up to 1600 Vickers. Pins of 7-9-10mm to be used in various lengths of the root canals. They can also be used in divergent roots thanks to the “Smartbox” housing that corrects up to 50 ° of divergence on two fixtures. Standard Equator caps can be used for Equator Pivot. 

 

The purpose of the OT Equator "Seeger System" is to create a passive connection for implant-supported bars. The elastic Seeger will correct all imperfections created by the chairside impression technique or laboratory casting process. This reduces the risk of the implant bar not seating passively.

 

Sphero Flex Implant Abutments are available for ALL narrow body implant systems.

The Sphero Flex implant abutments for overdenture attachments are compatible with any implant system currently on the market.

Easy to read, the color-coded millimeter measurement tool accurately measures tissue height from 0.5 - 7mm. The kit contains one cuff height slider gauge, one cuff height fixed rod gauge, one silicon ring dispenser and 20 silicon rings.

 

Custom Fit Abutment Services

Rhein83USA's custom attachment abutment design service is ideal for matching and reconstructing implant cases when there is little or no documentation identifying the existing implant fixture. This unique service enables the laboratory or dentist to ship the model or any part of the connection ie; healing cap etc. to the Rhein83 facility in Italy. There, the parts are scanned and reproduced to any size diameter with cuff heights from 1 mm to 7 mm using CAD/CAM technology. The implant attachment is milled, creating a perfect match between the new fabricated implant attachment and the original implant thread. Turn around time is 8 to 10 working days.
