A resin printer is a type of 3D printer that makes objects by curing (hardening) liquid resin with light. In dentistry, it is commonly used to produce highly detailed parts such as models, surgical guides, and temporary restorations. The “resin” is a light-activated plastic-like material, and the printer builds the object in thin layers. Dental clinics and labs use resin printer workflows as part of digital dentistry (intraoral scanning, CAD design, and fabrication).

3D printing is a way to make an object by building it layer by layer from a digital design. In dentistry, it is commonly used to create models, surgical guides, temporary restorations, dentures, and orthodontic appliances. It often starts with a digital scan of the mouth and computer-based design. The printed part is then cleaned, cured, and finished before being tried in or placed.

A **milling unit** is a computer-controlled machine that shapes dental materials by cutting (milling) them into a planned design. It is commonly used in **CAD/CAM dentistry**, where a digital scan is turned into a physical restoration. A milling unit is often found in dental clinics offering same-day crowns and in dental laboratories producing indirect restorations. In simple terms, it “carves” a tooth-colored block into a crown, inlay, onlay, veneer, or similar part.

chairside CAD/CAM is a dental workflow where restorations are designed on a computer and made in the dental office the same day. CAD means computer-aided design, and CAM means computer-aided manufacturing. It is commonly used to make crowns, inlays, onlays, and some veneers in a single appointment. It typically combines a digital scan, design software, and an in-office milling unit.

digital dentistry is the use of digital tools (scanners, software, and computer-controlled manufacturing) to plan and deliver dental care. It commonly replaces or complements traditional impressions, stone models, and manual laboratory steps. It is used in restorative dentistry (fillings, crowns), orthodontics (clear aligners), implant dentistry (surgical guides), and prosthodontics (dentures). The goal is to capture, design, and reproduce teeth and oral structures as accurate digital data.

CAD/CAM means computer-aided design and computer-aided manufacturing. In dentistry, it is a digital way to design and make restorations such as crowns, inlays, onlays, and veneers. It often uses an intraoral scanner (a small camera) instead of traditional impression trays. CAD/CAM is commonly used in dental offices (chairside) and dental laboratories.

A provisional restoration is a temporary dental repair placed to protect a tooth while a long-term plan is completed. It can replace missing tooth structure, cover a prepared tooth, or seal a treated area for a limited time. It is commonly used between appointments for crowns, bridges, veneers, implants, or larger fillings. It is also used when a dentist needs time to confirm comfort, bite, and appearance before the final restoration is made.

provisionalization is the process of making and placing a temporary dental restoration. It helps protect a tooth or implant site while a final restoration is being planned or fabricated. It is commonly used for temporary crowns, bridges, veneers, and short-term fillings. It can be done chairside in one visit or made indirectly in a lab or with CAD/CAM workflows.

A **trial smile** is a temporary, removable (or lightly attached) preview of proposed changes to a person’s teeth. It is commonly used in **cosmetic and restorative dentistry** to “test-drive” tooth shape, length, and smile line before definitive treatment. A trial smile may be made chairside with resin materials or produced from a lab/digital plan and transferred to the mouth with a silicone guide. It helps patients and clinicians visualize outcomes and refine a plan in a controlled, reversible way.

A mock-up is a temporary, removable or lightly bonded preview of a proposed dental result. It lets patients and clinicians “test-drive” changes in tooth shape, length, or smile contours before final treatment. It is commonly used in cosmetic dentistry, restorative planning (veneers, crowns, bonding), and interdisciplinary cases. A mock-up is a technique, not one single material, and it can be made in several ways.
