Brevis Chairside Technique
Uncover implants2
A registration of the dentures occlusal
relationship prior to the uncovering ofthe implants will assure that the denture
is not inappropriately displaced by the
abutment or its housing.

Brevis Chairside Technique
Rotate a combination of 0 and/or 15 angled abutments to achieve parallelism prior to their being
seated. Brevis abutments are available in heights of 2.0, 4.0 and 6.0mm.

Place soft wax in the denture to act as a pressure indicator to determine the relative position of theabutments. Alternatively, the top of the abutment may be marked with a felt tip pen to indicate thelocation of the abutment on the denture.

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

Remove rubber o-rings with a scaling
instrument or explorer.

Insert the explorer in between the o-ring
and Brevis housing and loosen theo-ring from the housing.

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.

Chairside Brevis Technique
Place soft wax to record relative position
of abutments.
1
Record position of abutments in soft wax.
Alternatively, abutments could be markedwith a wet ink prior to inserting denturefor recording an ink transfer mark.
2
Mark position of abutments on denture.
3
Liberally relieve denture to accommodateBrevis housings and confirm positionintra-orally.
4
Place rubber dam apron over abutments. Apply Vaseline under rubber dam apron.

Snap Brevis housing onto abutments. Sufficiently apply fluid acrylic to Brevis
housing to prevent displacement ofhousing upon insertion of denture.
Place minimal acrylic into relieved denture.
