selective grinding is a dental procedure that carefully reshapes small areas of tooth or restoration surface to improve how the upper and lower teeth meet. It is commonly used to adjust “high spots” (premature contacts) after fillings, crowns, bridges, or orthodontic changes. The goal is to create a more even, stable bite (occlusion) by removing minimal amounts of enamel or restorative material. It is also called occlusal adjustment or occlusal equilibration in some clinical contexts.

occlusal adjustment is a dental procedure that changes how the upper and lower teeth contact when you bite. It is done by carefully reshaping tooth or restoration surfaces, or sometimes by adding restorative material. The goal is to refine the “bite” (occlusion) so chewing forces are distributed more evenly. It is commonly used after fillings, crowns, bridges, dentures, and other dental treatments that can alter bite contacts.

mutually protected occlusion is an occlusal scheme (a planned way upper and lower teeth contact) used in many natural dentitions and restorative cases. In this concept, back teeth primarily support vertical biting forces, while front teeth help guide the jaw during side-to-side and forward movements. The “mutual protection” idea is that different tooth groups reduce stress on each other depending on how the jaw is moving. It is commonly discussed in restorative dentistry, prosthodontics, and occlusion teaching when planning crowns, veneers, composites, or full-mouth rehabilitation.

group function is an occlusal scheme (a way teeth contact during jaw movement). It describes multiple teeth on the working side touching together during side-to-side (lateral) movement. It is commonly discussed in restorative dentistry, prosthodontics, and occlusion when planning bite contacts. It is often compared with canine guidance, where the canine tooth carries most of the lateral contact.

canine guidance is an occlusal pattern where the canine teeth guide the jaw during side-to-side movement. In simple terms, the canines “take the load” when you slide your lower jaw left or right. This guidance can help reduce rubbing contact on back teeth during lateral movement. It is commonly discussed in bite analysis, restorative dentistry, prosthodontics, and occlusion (how teeth meet).

lingualized occlusion is an arrangement of denture teeth where the upper back teeth contact mainly on their tongue-side (lingual) cusps. It is designed to keep chewing forces more centered over the lower denture and supporting ridge. It is most commonly discussed in complete dentures and implant overdentures. It can also be used as a teaching-friendly compromise between fully anatomic and very flat occlusal schemes.

bilateral balanced occlusion is an occlusal scheme where the upper and lower teeth contact on both the left and right sides at the same time. It aims for simultaneous contacts in the “center” bite position and during side-to-side or forward movements. It is most commonly discussed in complete denture and removable prosthodontic treatment. In simple terms, it is designed to keep dentures from tipping when you chew or move your jaw.

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.
