How To Use A Dental Implant Impression To Get The Best Results Possible?

Fixed and removable restorations, such as single crowns, fixed bridgework, and implant-supported dentures, are retained by dental implants. Dental implants have a very high success rate and well-established technology. Implant dentistry is already widely used by dental offices and represents a sizable revenue stream. The need for the treatment will only grow as patient awareness rises.

Clinicians with experience understand the importance of meticulous implant placement and advanced planning. For the patient to have a successful prosthesis that closely mimics the look and functionality of natural teeth, a perfect implant impression is essential. Accurately documenting the implant fixture head's coronal location with respect to other oral structures is the main goal of taking an implant impression. For a good fit and long-term success, the prosthesis has to be fitted appropriately by the physician once it has been made and placed in the mouth.

Determining The Parts Of The Implant

Finding the implant's component parts is the first stage in the process because it will determine which parts are used for the impression. A unique set of imprint components is needed for each implant system; these components are made to perfectly fit over the implant's fixation head. This process may seem simple, but it's not always that simple, and you may need to consult the patient's notes. The parts and methods needed to take an impression are comparable after the implant system has been determined.

How To Choose An Impression Tray?

Impression trays can be created to order or purchased in stock. Because they are typically more rigid and are created to ensure that the proper thickness of imprint material is used, custom-made trays are usually a superior option. There are two types of trays used in implant prosthodontics: open and closed. The distinction is that, when the tray is situated in the patient's mouth, an open tray, as opposed to a closed tray, gives the doctor direct access to the implant fixture head.

Creating A Personalized Impression Tray

To create a personalized impression tray, a primary impression is needed. With regard to the positioning and angulation of the dental implants, the primary model will give a decent indication. It instructs the technician on the imprint material to use in order to place the proper spacer. A bespoke tray can be made to take an impression at the level of the fixture head, the abutment, or both at the same time.

Selecting Materials For Impressions

The impression substance you select should be precise, simple to blend, and quick to dry. Once extracted from the mouth, it needs to maintain its dimensional stability. The imprint material, such as vinyl poly siloxane or polyether compounds, should have good flow and high tear strength in order to accurately replicate the tissues. Desirable impression materials have strong wettability and are hydrophilic.

Choosing The Appropriate Screwdriver

An essential piece of equipment, an implant screwdriver is used to screw and unscrew implant components onto the fixture head. Depending on the implant system, screwdriver heads can have different shapes or be made to fit inside a torque device.

Healing Abutments Or Caps

A healing abutment or cap is often screwed onto the fixture head, which is level with the alveolar bone crest, either during implant placement or at a subsequent surgical procedure to expose the implant. Healing caps and abutments come in a variety of heights, profiles, and widths. The surgeon will choose the right size to help shape the peri-implant tissues as they heal. When creating a custom-tray, your dental lab will require the height of the healing abutment in order to estimate the thickness of the soft tissues and allow enough room for the implant components.

Coping With Impression

When taking an imprint, an impression coping is placed onto the fixture head or implant abutment. The imprint coping is kept in the mouth after the impression is extracted when a closed tray is utilized. When the imprint coping is taken from an open tray, it stays in the impression. The implant abutment or fixture head location will be transferred to the working model by the impression copings after the impression has been cast.


Abutments can be made to order or from stock to satisfy the patient's aesthetic requirements. Custom-made abutments are often manufactured with CADCAM technology, and its purpose is to conceal the point where the abutment and crown meet. Typically titanium, occasionally zirconia.

Methodical Approach To Closed Tray Impression

1. Remove the healing abutment to expose the fixture head, then choose a suitable closed tray impression coping to fit over it.

2. Use a radiograph to ensure that the coping is seated if you are uncertain about its placement.

3. Test the stock or personalized tray. It needs to enclose the whole arch. Make sure there is enough vertical room for the impression material and the impression coping.

4. Fill the remainder of the tray with high-viscosity or heavy-bodied impression material, then inject light-bodied, low-viscosity impression material around the implant and the surrounding soft tissue. Avoid using excessive amounts of light-bodied impression material since it does not have the necessary stiffness for a high-quality implant impression.

5. Carefully remove the impression after the substance has solidified, leaving the coping in the mouth.

6. Take the imprint coping out of the mouth and put it back in the impression, making sure it moves in the right direction. Usually, there will be a tactile or auditory "click."

7. Change out the mending abutment.

Over the implant, a piece or window is cut out of a custom-tray.

1.Fit an imprint coping after removing the healed abutment. For further stability, splint several copings together in the mouth if needed.

2. Make sure the impression coping is level with the window by trying it in the custom-tray. The placement of the impression copings makes removal simple and guarantees that the impression material supports the copings sufficiently.

3. Use wax to seal the window. The impression coping tips need to be perceptible through the wax.

4. After taking the impression using the proper impression substance, let it harden.

5. Use the window to reach and detach the impression copings after they have been installed. Keeping the impression copings in place, remove the impression from the mouth.

6. Replace the healing abutments at the end.

After taking an implant imprint, check it to make sure the technician can precisely match the tooth outlines by recording all of the teeth. The impression and analogs must be the stable foundation of the impression coping. Prior to casting, implant replicas are fastened to the coping.
