balanced occlusion is an occlusal scheme (a planned way teeth contact) designed to keep dentures stable during jaw movements. It aims for simultaneous contacts on both the right and left sides when the jaw moves forward or sideways. In plain terms, it is a “steady contact pattern” intended to reduce tipping of removable dentures. It is most commonly discussed in complete denture dentistry and, in some cases, removable partial dentures and overdentures.

The curve of Wilson is the side-to-side (left-to-right) curvature of the biting surfaces of the back teeth. It describes how the cusps (the “points” on molars and premolars) line up when viewed from the front. In the lower jaw it is typically concave, and in the upper jaw it is typically convex. It is commonly used in dental occlusion (how teeth fit together), restorative dentistry, orthodontics, and prosthodontics.

The **curve of Spee** is the natural front-to-back curvature of the biting surfaces of the lower teeth. It is described by imagining a line that follows the cusps (tips) of the teeth from the canine toward the back molars. Dentists use it to understand **how teeth meet (occlusion)** and how the bite is balanced during chewing. It is commonly referenced in **orthodontics, prosthodontics, and restorative dentistry** when planning bite changes.

The **occlusal plane** is an imaginary, flat reference surface that represents how the chewing surfaces of the teeth are oriented. In simple terms, it helps describe whether the teeth “line up” in a level, even way from front to back and side to side. Dentists use it in restorative dentistry, orthodontics, and prosthodontics (crowns, bridges, dentures) to plan and evaluate a bite. It is a **planning and measurement concept**, not a dental material or a single procedure.

A fully adjustable articulator is a mechanical device that holds dental casts (models of your teeth) to simulate jaw movements. It is used to study how the upper and lower teeth meet (occlusion) outside the mouth. In many cases, it is used in dental laboratories and in complex restorative and prosthodontic planning. Its goal is to reproduce a patient’s jaw mechanics as closely as practical, based on clinical records.

A semi-adjustable articulator is a mechanical device that holds dental models (casts) to simulate how the upper and lower jaws meet. It helps a dentist or dental technician reproduce common jaw movements outside the mouth. It is commonly used in prosthodontics (crowns, bridges, dentures) and occlusion-focused treatment planning. It sits between a simple “hinge” model holder and a fully adjustable articulator in complexity.

An articulator is a mechanical device used to hold dental models (casts) of the upper and lower jaws. It helps simulate how the teeth meet (occlude) and how the jaw may move during chewing and speaking. articulator is commonly used in dental laboratories and clinics when designing crowns, bridges, dentures, and bite guards. It lets clinicians and technicians evaluate the “bite” outside the mouth in a controlled way.

facebow transfer is a method of recording how your upper jaw relates to your skull and jaw joints. It helps a dental lab mount a maxillary cast (upper teeth model) on an articulator (a jaw simulator) in a more individualized position. It is most commonly used in prosthodontics and restorative dentistry when making crowns, bridges, dentures, or complex bite reconstructions. It can also be used during treatment planning to study how the bite may function outside the mouth.

freeway space is the small separation between the upper and lower teeth when the jaw is at rest. It is also called the “interocclusal rest space” in many dental texts. It is commonly discussed when planning dentures, bite changes, and full-mouth rehabilitation. It helps clinicians describe how the jaw closes from a relaxed position into tooth contact.

vertical dimension at rest is the natural distance between the upper and lower jaws when your jaw muscles are relaxed and your teeth are not touching. It describes a facial “resting” posture, not a dental material or a treatment by itself. Dentists use it most often when planning dentures, bite changes, and full-mouth rehabilitation. It is commonly compared with the vertical dimension when teeth are together to estimate normal “freeway space.”
