Use an occlusal registration jig to prevent inadvertent displacement of the denture during

the chairside technique.

Use the 15 Brevis abutment to help achieve parallelism for non-parallel implants.

The denture should NOT rock or pivot on the abutments or the housings.

Do not make a direct impression of the overdenture abutments.

Use a rubber dam and Vaseline to prevent locking of the denture beneath the undercut

of the abutments.

Place acrylic into a syringe for ease of use and greater control.

A too viscous mix of acrylic may inappropriately displace the orientation of the Brevis housing

on the abutment.

It is essential for the patient to clench bilaterally on cotton rolls to ensure proper seating of the

housings in the denture.

If the denture is too retentive, slightly relieve the inside of the o-ring lumen with a round bur.

A common cause of accelerated o-ring wear is a Brevis housing whose retentive acrylic was

polymerized while the Brevis housing was not appropriately aligned on the abutment.

Note: If the denture is inadvertently locked onto the Brevis abutment, it is advisable to tap it off rather than

attempting to cut it off.

The denture may be notched to facilitate the placement of a tapping instrument. Either the denture will

be removed from the abutment or the abutment will be removed from the implant.


Polish the excess acrylic around theBrevis housings after the removal of therubber dam.

The design of the Bicon abutment system is such that the hemispherical base of the abutment

does not sit ush with the neck of the implant. By design, there is a space below the abutmentpost when the abutment is fully seated. When viewing this on a radiograph, it can be seen as aradiolucency. please nte that the st any autent ay nt e fe. lterng theautent st n any anner r usng a eentng eu wll aet the rtnal ft the lng taer resultng n a tentally nn-retentve autent. The following diagramdepicts the nal seating of a Brevis abutment as well as the method for measuring each abutment.

3Measurement Guide

The height of the Brevis abutment is measured from thetop of the implant to the shoulder of the Brevis abutment.

The available heights are 2.0, 4.0 or 6.0mm. The total heightfrom the top of the implant to the top of the abutment isapproximately 5.0, 7.0 or 9.0mm, respectively.

Rubber O-Ring Maintenance

Each patient maintains and inserts his denture dierently. The o-ring should be changed every 6 to 24

months depending upon its wear.

The o-rings should not be soaked in a solution with high alcohol content. Some cleaning solutions

may dry out the rubber o-rings and cause them to lose retention faster than normal.

An inappropriately aligned housing will result in excessive wear of the rubber o-ring.

If excessive wear of o-ring is noted, remove and re-align the housing in denture with a suciently

owable acrylic injected onto the housing and into the relieved denture.

Place soft wax to record relative position

of abutments.

Record position of abutments in soft wax.

Alternatively, abutments could be markedwith a wet ink prior to inserting denturefor recording an ink transfer mark.

abutment is measured from

the top of the implant to

the shoulder of the Brevisabutment. The available

heights are 2.0, 4.0 or 6.0mm.

The total height from the top
