A **scan body** is a small, temporary component attached to a dental implant or implant abutment during digital impression making. It helps an intraoral scanner “see” the exact 3D position and orientation of the implant connection. A scan body is most commonly used in **implant dentistry** and **CAD/CAM** (computer-aided design and manufacturing) workflows. It is removed after scanning and is not intended to stay in the mouth as a long-term part.

An implant analog is a precisely made metal (or polymer) replica of a dental implant connection used outside the mouth. It is placed into an impression or a working model so the laboratory can reproduce the implant’s exact position. It helps the lab fabricate crowns, bridges, or dentures that fit the implant accurately. It is most commonly used in prosthodontics and dental laboratory workflows.

An **abutment-level impression** is a dental impression made after an implant abutment is placed, so the impression records the *abutment* rather than the implant fixture itself. It helps a lab create a crown, bridge, or other restoration that fits the abutment’s shape and margin (the edge where the restoration meets the abutment). It is commonly used in implant dentistry when the clinician plans to keep the same abutment in place for the final restoration. It can be done with conventional impression materials or, in some workflows, with digital scanning—depending on the system and clinical situation.

A closed-tray impression is a dental impression technique commonly used for implant dentistry. It records the position and angle of a dental implant so a lab can make a crown, bridge, or other restoration. “Closed-tray” means the impression tray stays in the mouth while the implant coping remains attached until after the tray is removed. It is often used when access is limited or when a simpler, quicker transfer method is appropriate.

An open-tray impression is a dental impression technique where a tray has an opening that lets the clinician access and unscrew impression copings through the tray. It is commonly used for dental implants to capture the exact position and angle of implants in the mouth. The goal is to transfer implant location information to a working model (cast) in the laboratory. It is also called a “pick-up” implant impression in many clinical settings.

An implant impression is a record of the position and shape of a dental implant in the mouth. It helps a dental laboratory or digital workflow make a crown, bridge, or denture that fits the implant accurately. It is commonly used after an implant has healed and the dentist is ready to plan the final restoration. It can be taken with traditional impression materials or with a digital scan, depending on the system and case.

A surgical guide is a custom-made template that helps a clinician position surgical instruments in a planned location and angulation. It is most commonly used in dental implant surgery to guide drilling and implant placement. Depending on the case, the surgical guide may rest on teeth, gum tissue, or bone. The goal is to transfer a planned position (often created from scans) into the mouth as accurately as practical.

guided surgery is a method of performing dental surgery using a custom-made guide or real-time navigation based on a digital plan. It is most commonly discussed for dental implant placement, but it can also support other oral surgical steps. The goal is to translate a virtual treatment plan into the patient’s mouth as accurately as possible. It is typically used in practices that combine 3D imaging, digital impressions, and CAD/CAM manufacturing.

implant planning is the process of deciding where and how a dental implant will be placed before any surgery begins. It combines clinical examination with imaging (often 3D scans) to map bone, teeth, and nearby anatomy. It is commonly used in dental implant therapy to support predictable positioning and restoration design. It helps align surgical steps with the intended final tooth (the crown) rather than placing an implant “in isolation.”

A Michigan splint is a rigid, removable dental appliance that covers the biting surfaces of the teeth, most commonly on the upper jaw. It is designed to provide a stable, even contact between the upper and lower teeth during jaw function. Clinicians often use it in the evaluation and management of tooth grinding (bruxism) and temporomandibular disorders (TMD). It is also used as a diagnostic tool to help assess how the bite and jaw muscles respond to a more stable occlusal position.
