The height, profile, and width of healing caps or abutments vary, and the surgeon will select an appropriate size to shape the peri-implant tissues during healing. Usually, the fixture head is level with the alveolar bone crest, and a healing abutment or cap is screwed onto the head at the time of implant placement or during a second surgical procedure to uncover the implant. Screwdriver heads vary in shape according to the implant system and can be designed to fit into a torque device. Impression materials with desirable properties are hydrophilic and have good wettability.Īn implant screwdriver is used to screw and unscrew implant components onto the fixture head and is a critical piece of equipment. The impression material provides an accurate representation of the tissues and should have good flow and high tear strength, like vinyl poly siloxane, or polyether materials. After removal from the mouth, it must remain dimensionally stable. Your chosen impression material should be accurate, easy to mix, and rapid to set. A custom tray is designed to take an impression at abutment level, at fixture head level, or at both in the same impression. It tells the technician which impression material to use so that an appropriate spacer can be laid down. The primary model will provide a good idea as to the angulation and position of the dental implants. The difference is that, unlike a closed tray, an open tray allows the clinician direct access to the implant fixture head while the tray is seated in the mouth.Ī primary impression is required to fabricate a custom impression tray. Trays used for implant prosthodontics are categorized as open or closed. Usually, custom-made trays are a better choice because they tend to be more rigid and are fabricated to ensure that an optimal thickness of impression material is used. Impression trays can be stock trays or custom-made. Once the implant system has been identified, the components and techniques used when taking an impression are similar. Although this step might sound easy, it’s not always straightforward, and it might be necessary to refer to the patient’s notes. Each implant system requires its own set of impression components, which are designed to fit precisely onto the fixture head of the implant. The first step of the procedure is to identify the implant components because this will dictate the impression components used. Once the prosthesis is fabricated and seated in the mouth, the clinician must fit it correctly to achieve a passive fit and long-term success. The primary objective when taking an implant impression is to accurately record the coronal position of the implant fixture head in relation to other structures in the mouth. An accurate implant impression is fundamental to giving the patient a successful prosthesis that closely resembles the appearance and function of natural teeth. As patient awareness increases, demand for the treatment will only increase.Įxperienced clinicians know that advanced planning and precise implant placement are vital. Many dental practices have already embraced implant dentistry, and it is a significant source of revenue. The technology for dental implants is well-established, and success rates are extremely high. Dental implants retain fixed and removable restorations, including single crowns, fixed bridgework, and implant-supported dentures.
