The correct spelling of the word "Occlusal Guidances" is "ˈɒklʊzəl ˈɡaɪdənsɪz." The first part of the word, "Occlusal," refers to the way upper and lower teeth fit together, and is pronounced with a short "o" sound followed by a "k" and an "s." The second part of the word, "Guidances," is pronounced with a long "i" sound, and refers to instructions or directions. Together, "Occlusal Guidances" refers to instructions for how teeth fit together in the mouth.
Occlusal guidances refer to mechanical and functional components that control the contact and movement of the teeth and their supporting structures during various oral functions, particularly during the process of chewing or biting. It is an important concept in dentistry that helps ensure efficient and harmonious functioning of the teeth and jaw.
In the context of dental occlusion, or the relationship between the upper and lower teeth when they come together, occlusal guidances play a crucial role in determining the stability and balanced functioning of the jaw joint, or the temporomandibular joint (TMJ). They ensure that the forces generated during biting and chewing are evenly distributed across the dental arches, preventing excessive stress on specific teeth or areas of the mouth.
Occlusal guidances may include various types of occlusal contacts, such as cuspal inclines, ridges, and prominent dental structures, that dictate the direction and timing of tooth contacts during jaw movements. These contacts can influence jaw positioning, muscle activity, and jaw stability.
Dentists and dental technicians carefully consider occlusal guidances when designing and adjusting dental restorations, such as dental crowns, bridges, or dentures, as they need to mimic the natural occlusion and ensure optimal function and longevity of the restorations. Occlusal analysis and adjustments may be required to achieve an ideal occlusion and maintain proper occlusal guidances.
Overall, occlusal guidances are crucial for preserving the integrity, stability, and optimal functioning of the oral structures, allowing for efficient chewing and biting while minimizing the risk of tooth wear, muscle strain, and temporomandibular joint disorders.
The word "occlusal guidances" is derived from the combination of two terms: "occlusal" and "guidance".
1. Occlusal: The term "occlusal" is derived from the Latin word "occlusus", which means "shut" or "closed". In dentistry, the word is used to refer to the contact between the biting surfaces of the upper and lower teeth when the jaws are closed.
2. Guidance: The term "guidance" comes from the Middle English word "guide", which is rooted in the Old French word "guider" and originally from the Frankish word "witan" (to show the way). It refers to giving direction, leading, or advising someone in the correct course of action.
Therefore, "occlusal guidances" in dentistry refers to the process of guiding the contact between the upper and lower teeth during biting and chewing.
