11. The Implant System –
Tri-channel Internal Connection
Tactile and Easy to Use
Accurate prosthetic positioning
Internal connection with three channels that provide accurate and
repeatable indexing of abutment to implant. Positive lock is
noticeable when seating an abutment and the abutment is situated
correctly in the connection. Once locked, the internal connection
resists rotation.
Secure abutment placement
Three interlocking channels guide correct abutment placement also
in sites with poor visibility and limited inter-occlusal space may
compromise the clinician’s ability to manipulate the abutment.
Prosthetic versatility
Tri-channel connections supports all forms of restorative solutions

Closed Tray Impressions:
Closed-Tray Impression Copings are indicated for:
•single implant cases
•multiple implant cases when the implants are parallel so that the impression
can be removed from the mouth without tearing the impression
Some Closed-Tray Impression Copings stay in the mouth when the impression is
removed. They must be loosened from the implants after the impression is taken and
they must be reinserted into the impression before pouring the stone.
22
23. The Implant System - Parts
Open Tray Impressions:
Open-Tray Impression Copings should be used when the
implant(s) are not parallel to each other or the natural teeth and it
is unlikely that the impression can be removed from the mouth
without tearing the impression material.
Open-Tray Impression Copings are
attached to the implants by means
of a long abutment screw.
Open-Tray Impression Copings will stay in the impression when it
is removed. So they must be loosened from the implants after the
impression material has set.
23
24. The Implant System - Parts
Open Tray Impressions:
To loosen the screw and free the impression coping from the implant, the screw
of the impression coping must extend through the impression tray so that it can
be loosened. The impression tray must be modified to allow access to the
screw.

29. The Implant System - Parts
Maintenance:
Implants can only be cleaned with implant-specific cleaning instruments that can clean
plaque and tartar, but will not scratch the surface. Tartar does not penetrate the implant
surface like it does on natural teeth, so it does not require the same planing action to
clean the tartar.
Do not use metal instruments around implants to avoid scratching the surface. Scratched
surfaces attract more bacteria that could lead to tissue inflammation around the implant.
Although a metal perio probe can be used to measure the tissue height, it should NEVER
be used to probe the “sulcus.” The tissue does not attach to an implant as it does to a
tooth, and probing will disrupt the tissue junction.

30. The Implant System - Fit
FIT OF ANY PART TO THE IMPLANT IS CRITICAL !
To verify FIT, a verification x-ray is taken every time any
abutment, impression coping, or temporary abutment is
attached directly to the implant.

FIT OF ANY PART TO THE IMPLANT IS CRITICAL !
How to identify inadequate fit:
31
32. Exercise # 1
Posterior Single Units – Snappy Abutment™
Hot Clinical Tip !
DO NOT ANESTHETIZE WHEN SEATING ABUTMENTS
OR COPINGS ONTO THE IMPLANT. Patients should feel
no discomfort when placing and removing implant parts. If
there is discomfort, check for the cause – something is
wrong. Most often, discomfort from placing parts directly
onto the Implant is due to small areas where the soft tissue
has grown or collapsed over the Implant margins and that
tissue is being pinched between the parts. When this is the
case, anesthetize and then use a tissue punch to clear
away the offending soft tissue.

FOR MULTIPLE UNITS CONNECTED BY A BAR OR

34
35. The Implant System - Fit
FOR MULTIPLE UNITS CONNECTED BY A BAR OR
SPLINTED, PASSIVE FIT IS CRITICAL !!
Implants will never accommodate to even a slight framework misfit !!
For that reason ALMOST ALL multiple unit cases
will require indexing and soldering of the
connectors, including bar connectors. It is best to
request all abutments/crowns be sent as individual
pieces, rather than try to see if a one piece prosthetic
will fit.
Index in the mouth using a product like Zap-It. Send
back to the lab for soldering. Try-in after soldering
and verify with an X-ray. It is sometimes necessary
to index and solder each connector one at a time.
But there is no substitute for passive fit.

DISINFECT THE IMPLANT AND THE IMPLANT PARTS.
In many cases, when you remove implant parts from the
mouth, there will be a bad odor from bacteria that get into
and around the connections. Always keep chlorhexadine
gluconate 4.0% (Peridex) on hand and use a syringe to
flush the implant, screw openings and soft tissues. It is a
good idea to place all parts in a small cup of chlorhexadine
as they are taken from the mouth.

proper treatment plan addressing patient chief complaint keeping in considering all medical, dental, economical conditions and limitations for restoration that has good prognosis . Implant is replacement for missing tooth . Nothing can replace natural tooth when its lost there fore the expectation must be realistic and risk and benefits must be discussed before treatment
The Snappy Abutment is available in two heights 4.0 and 5.5mm, with an available collar height of 0.5mm and 1.5mm collar. A 0.75 mm collar is also available for out NP implant.
When designing a tissue borne overdenture that is being secured with implants here are some minimal guidelines to follow: Mandible: 2 or more implants The Locator Abutment is available in multiple collar heights to accommodate variable tissue levels and can support Either a narrow, regular, or wide implant platform.
After hand tightening, Dr. Bain will utilize the torque wrench and tighten the abutments to 35 Ncm.
The first category we are going to discuss is a patient that currently has a well fitting denture.
Here are the steps to follow: Select the height of the abutment by determining the height of the gingiva at its highest point. The ideal abutment will be exposed a minimum of 1.5 mm over the tissue to make room for the attachment housing Choose the corresponding abutment tissue cuff height or the next closest higher size available .
Place a white block-out spacer ring on each abutment. The spacer ring is used to block out the area surrounding the abutment. Place the metal caps with the black processing males onto the Locator Abutments.
Use an appropriate method to mark the locations of the Locator Abutments on the existing denture. Hollow out the existing denture base in the areas of the Locator Denture Caps. Add: Ensure that the denture caps are fixed on the abutments and do not touch the prosthesis. A method of doing this will be shown on a clinical case to follow.
Caution: You may not be able to remove the denture if resin flows into undercuts around attachments and is cured. To prevent resin from flowing under the caps, two or more Locator block-out spacers can be stacked. Use the ChairsideLightcure Acrylic Resin Syringe Kit (Zest order No. 9403) to light cure bond the Locator Denture Cap Processing Male Assembly into the Denture, or mix a permanent self-curing acrylic and place a small amount in the recess of the denture and around the metal cap of the Locator Denture Cap Processing Male Assembly. Insert the denture into position in the oral cavity. Guide the patient into occlusion, maintaining a proper relationship with the opposing arch. Maintain the denture in a passive condition, without compression of the soft tissue, while the acrylic sets. Excessive occlusal pressure during the setting time may cause tissue recoil against the denture base and could contribute to dislodging and wear of the nylon males. After the acrylic resin has cured, remove the denture and discard the White Block-Out Spacer. Use a bur to remove excess acrylic, and polish the denture base before changing to the final male.
After the housing is cured, the black processing male is removed. Select replacement males by considering preferred retention and angle or implant divergence. Note: Initially, select replacement males with the lowest retention values.

We will now review a clinical case using this method. First Dr. Bain is going to remove the healing abutment, and replace it with the Locator Abutment and hand tighten.
Here we see Dr. Bain hand-tightening the abutments using the Locator Abutment Driver.
Hand tighten the Locator Abutment to the implant using the Latch Type Torque Wrench Driver connected to the Manual Toque Wrench Adapter Prosthetic. Tighten the abutment to 35Ncm using the Manual Torque Wrench Prosthetic.
The Locator Abutments are installed with a minimum 1.5 mm of the abutment exposed above the soft tissue. For the chairside processing of the attachments, the area of the denture to receive the attachment needs to be relieved to create space for the attachment housing. This is accomplished in several steps.
The first step on the abutment side is to place the white block-out spacer over the Locator abutment. Next Dr. Bain will place the metal housing with the black processing male. Note that the black processing male in the titanium housing suspends the attachment in the most vertically removed position, to accommodate for the tissue resilience that will be built in to the retentive attachments substituted after processing.
The area of contact is identified and marked with an indelible pencil
After that procedure, clean the site with some alcohol. The process is repeated as necessary until a completely passive “soft tissue only” seating of the denture is possible without any interference from the Male Processing Attachment. The metal housing is also thoroughly dried,
Then Paint Triad VLC Bonding Agent Onto Housings, then Brush on Light-Cured Gel.
Then we’re going to seat the denture.
Dr. Bain is now going to is remove the black processing male.
EZ Steps Module Rev 0.0 The denture is inserted in the patient, occlusion and final retention is checked.
The next category or situation we are going to review is a Denture needing a reline.
Speaker Note: Detailed instructions with figures to review are available on the ZestAnchor website http://www.zestanchors.com/images/articles/article_6_L8002-TM%20REV%20F.pdf For a denture that requires are reline, the steps are: Insertion of the proper Locator Implant Abutment at tissue level must be completed before beginning the procedure for placement of the Locator Denture Cap Processing Male Assembly. 2. Place a White Block-Out Spacer over the head of each Locator Abutment. The spacer is used to block out the area immediately surrounding the abutment. The space created will allow the full resilient function of the pivoting metal denture cap over the Locator Black Processing Replacement Male. NOTE: If the White Block-Out Spacer does not completely fill the space between the tissue and the metal denture cap, it is necessary to block out any remaining undercuts to prevent the added acrylic resin from locking the denture onto the abutment. This can be accomplished by stacking more Block-Out Spacers. 3. Insert a Locator Denture Cap Processing Male Assembly onto each Locator Implant Abutment, leaving the White Block-Out Spacer beneath it. The Black Processing Replacement Male will maintain the overdenture in the upper limit of its vertical resiliency during the processing procedure. 4. Prepare a recess in the denture to accommodate the protruding Locator Denture Cap Processing Male Assembly. There must be no contact between the denture and the titanium cap. If the denture rests on the metal cap, excess pressure on the implant will result. After passive soft tissue support for the denture over the Locator attachments has been achieved, a reline impression using an elastomeric impression material is made following all full denture principles for border extension. The male processing caps will likely be removed when the denture and impression are removed. If not, the processing male housing is removed and sent to the dental technician. Analogs for the appropriate Locator abutment will be placed in the processing caps and a model poured and mounted on a reline articulator.
When a new denture is necessary, the Locator abutments are still installed before the denture fabrication begins. Then the procedure changes only slightly, in that, impression copings are used on the individual Locator abutments to produce a cast that the denture baseplates are fabricated on.
To make the cast shown in the previous slide, Locator impression copings are used that are picked up in the impression of the lower jaw. Take an impression utilizing the muco-dynamic technique. Send to impression to the dental laboratory.
In this case Dr. Schneider is actually using the older style impression coping. The current impression copings only have one ring.
Here we see the final impression, with the Locator impression copings picked up.
On the left hand side you can see the blue 1.5 replacement male that has been inserted.
