Accurate impressions provide a foundation for successful implant prosthodontics. This paper is aimed at the general dental practitioner GDP who would like to start restoring dental implants and demystifies the terminology, introduces the basic armamentarium and discusses the relative merits of different implant impression techniques.

Detailed, step-by-step instructions for making impressions using the closed and open tray techniques are provided and the importance of verification jigs are highlighted. Clinical relevance A successful restoration is dependent upon proper planning and meticulous clinical processes. An understanding of impression techniques is therefore fundamental for the GDP wishing to restore implant-supported prostheses.

Objectives The reader should be familiar with different implant components and understand the impression techniques used in implant dentistry. Aims to introduce the general dental practitioner to the armamentarium of implant dentistry and provide instructions for making accurate impressions in implant retained prosthodontics.

The reader will understand the need for various techniques and appreciate the use of abutments and verification jigs. Dental implants can be used to retain single crowns, fixed partial dentures, full arch bridgework and removable prostheses.

The use of dental implants is well established 1 and high survival rates have been reported. Dental practitioners may be involved in the planning, placement and restoration of dental implants and an accurate impression is vital if the patient is to be provided with a successful prosthesis.

The object of making an impression in implant dentistry is to accurately relate the position of the most coronal portion of the implant implant fixture head to other structures within the oral cavity.

Once fabricated, the clinician has to ensure that the prosthesis is seated correctly and fits passively, as a passive fit is essential for long-term treatment success.

To effectively carry out any procedure, it is crucial to familiarise oneself with the components involved. Each implant system has its own set of impression components that are designed to fit accurately onto the fixture head of the implant, which is machined to specific geometry.

Irrespective of the implant system used, the impression components and techniques are broadly very similar.

Similar to crown and bridge prosthodontics, impression trays can either be stock trays or custom made trays. Custom trays are preferred as they are generally more rigid and permit the impression material to be used in its optimal thickness.

In implant prosthodontics, trays can further be classified as open Fig. An open tray permits direct access to the implant fixture head with the tray seated intra-orally. The advantages and disadvantages of these techniques will be discussed later in this article. A custom tray can be used to make an impression at fixture head level, abutment level or both within the same impression. A primary impression is a prerequisite for the construction of the custom tray.

Careful examination of the primary model will give a good indication of the position and angulation of the implants. The clinician should provide the technician with their choice of impression material, so that the appropriate spacer can be laid down.

The authors recommend the use of rigid acrylic resin as the custom tray material. The impression material used should be easy to mix, accurate, rapidly setting and dimensionally stable following removal from the mouth. An implant screwdriver is a critical piece of equipment used to screw and unscrew various components onto the fixture head. Depending on the implant system, screwdrivers heads can be slotted, hexagonal, star shaped, etc Fig.

Screwdrivers are often designed to fit into a manual or motor driven torque device, which can be used to tighten components to a predetermined torque Fig. An appropriate healing abutment is selected to mould the peri-implant tissues during healing and prevent tissue overgrowth.

When ordering a custom tray, it is important to provide information regarding the height of the healing abutment, to ensure that the technician can estimate the thickness of the soft tissues and provide adequate space for the requisite components.

The impression coping is the component that fits onto the implant fixture head or an implant abutment discussed later while making an impression. Broadly speaking, there are two types of impression copings: one that is used with a closed tray and retained in the mouth after the impression is removed Fig.

Certain clinical situations, eg unfavourably positioned implants, the need to support adjacent soft tissues, poor access, etc dictate the need for a custom impression coping. While trimming and roughening the impression coping, care should be taken not to damage the portion of the impression coping that engages within the fixture head.

This can be done by screwing the impression coping onto an implant replica while trimming. Once trimmed, the authors prefer to screw the impression coping into the implant and add flowable composite into the space between the coping and soft tissues. It is important to ensure that there is haemostasis during the addition of composite. Following the initial composite addition, further increments can be made either with the impression coping in situ or extraorally, until the soft tissues are adequately supported.

When implant positioning is optimal the prosthetic superstructure can be screwed directly on the fixture head. However, this is not possible if the implant angulation is unfavourable, the fixture head is deeply placed or implants are divergent. In these circumstances, implant angulation or depth can be corrected with an intermediary abutment. These are available in a variety of materials eg titanium, zirconia, etc. Prefabricated stock abutments are off-the-shelf components produced in a variety of collar heights, widths and angulations.

These are available in titanium, gold and ceramic and can be screwed or press fitted with some systems directly to the fixture head before impression making. Alternatively, an impression of the prefabricated abutment can be made using conventional crown and bridge impression techniques. Prefabricated abutments must be carefully selected with the final prosthesis in mind.

Abutment analogues can be useful to select the correct standard abutment. Where multiple implants are involved it is often necessary to select standard abutments following analysis of a fixture head model.

Prefabricated abutments are relatively cheap and they simplify impression making by moving the restoration margin coronally. However, they come in a relatively limited number of shapes and sizes and are inappropriate in all circumstances, especially when the fixture head is deeply subgingival. Custom abutments, individualised for each restoration, can be used where prefabricated abutments are inadequate.

Custom abutments are generally more expensive than prefabricated abutments. However, they can be designed so that the abutment-crown junction is hidden to ensure superior aesthetics.

One-piece implants Figs 13a-d incorporate an integral abutment. This abutment is usually prepared using special burs designed to cut titanium. Care must, however, be taken to ensure that the implant is not overheated and the abutment is not excessively reduced. A conventional crown and bridge impression is made of the prepared abutment. These one-piece implants can be obtained in narrow diameters and are particularly useful in the replacement of mandibular incisors.

However, abutment preparation is irreversible therefore the long-term prognosis of adjacent teeth must be carefully considered as the implant may need to be used as a part of a bridge in the future. Two techniques are commonly employed to make an impression of the fixture head: the closed tray and open tray techniques.

A closed-tray impression coping, appropriate to the type and size of implant, is selected and fitted onto the exposed fixture head Fig.

If the clinician is unsure about the complete seating of the coping onto the fixture head, a confirmatory radiograph should be taken An appropriate stock tray or a closed custom tray is tried in. It is important to ensure that the tray covers the entire arch, provides adequate vertical space for the impression coping and optimum space for the impression material. The authors generally use a combination of light bodied and heavy bodied silicone in a manner similar to conventional crown and bridge impressions Fig.

Care must, however, be taken not to use too much light bodied material as it tends to be less rigid and may affect the repositioning of the impression coping. Once set, the impression is removed, leaving the impression coping in the mouth Fig. The impression coping is then removed and manually repositioned into the impression Fig. It is important that the coping relocates positively and it is critical to ensure that the geometric details of the impression coping is recorded accurately in the impression Fig.

Plastic impression copings that press-fit onto the fixture head may be used with the closed tray technique Fig. These copings get embedded within the impression material and are removed from the mouth in situ within the impression. However, there is a small risk of dislodging the impression coping during impression taking and removal.

A rigid custom tray is manufactured with a window cut through over the implant see section of tray design for further detail. Appropriate impression copings are selected and fitted Figs 17a. In some cases, these copings may be splinted together intraorally to provide greater rigidity and possibly greater accuracy.

The open tray is tried in — the impression copings should emerge level with the window. This permits easy removal of the impression copings, while ensuring that the copings are supported by sufficient impression material.

The window is sealed with wax Fig. An impression is taken in the open tray with a silicone impression material. The tips of the impression copings should be felt through the wax covering the window Fig. Once the impression has set, the impression copings are unscrewed through the window on the tray and the impression is removed from the mouth along with all the impression copings in place Fig.

The authors have found that a closed tray impression technique is generally simpler and quicker but involves reseating the impression coping, which may introduce potential inaccuracies.

A recent systematic review on impression techniques showed that in situations where there are three or fewer implants, there was no difference between an open tray and closed tray approach. However, if there were four or more implants, impressions appeared more accurate with an open tray technique. Within general dental practice, there is often a need to replace an implant crown, which is aesthetically unsatisfactory, while the underlying abutment is satisfactory.

In these situations, a routine crown and bridge approach may be employed, ie the gingivae may be retracted using displacement cord Fig. Care must be taken not to damage the fragile epithelial attachment to the abutment. Alternately, the implant crown can be overcontoured along the gingival margin by adding a small amount of composite resin, following which the crown is reseated for 5—10 minutes. This will displace the gingival tissue and permit an accurate impression of the abutment to be made.

This technique has the advantage of not disrupting the epithelial attachment around the abutment. Once an impression has been made, the impression should be thoroughly inspected. All teeth should be accurately recorded to allow future articulation and replication of contralateral tooth contours.

The impression coping should be securely located within the impression.

We look forward to providing you with compassionate care and a beautiful smile! There are two main types of impression trays: stock trays and special trays. After the liquid material is poured into the tray, it is then placed onto either the upper or lower set of teeth so that it covers the entire dental arch. Orthodontic Bands and Your Braces. The particular type of liquid that is utilized for impression taking varies based on what the impression is needed for.
