Night guard terminology can get confusing, so let’s break down what exactly an occlusal guard is real quick, and how it can help with your teeth grinding.

The definition of occlusion in dentistry

In dentistry, occlusion refers to the contact between the upper and lower teeth when the jaw is closed. This is an essential aspect of oral health, as proper occlusion ensures that the teeth and jaw are aligned correctly, allowing for efficient chewing, speaking, and overall comfort. The term “occlusal guard” is derived from this concept, as the primary purpose of these devices is to protect the teeth and jaw from damage due to improper occlusion or other issues.

Other names for occlusal guards

Occlusal guards are known by various names, often depending on their specific purpose or use. Some of these names include:

• Night guard
• Dental night guard
• Grind guard
• Bruxism protector
• Teeth Shield
• Bite guard
• Occlusal guard
• TMJ Mouth guard
• Night retainer
• Tooth protector
• Teeth guard
• Sleep guard
• Bruxism splint
• Clench guard
• Grinding retainer
• Bruxism guard

Occlusal splints

Occlusal splints are a type of occlusal guard that is typically custom-made to fit the user’s mouth. These devices may or may not differ from traditional occlusal guards, depending on the specific type and purpose of the splint. There are several different types of occlusal splints, including:

Repositioning splints

Repositioning splints, also known as anterior repositioning splints, are designed to reposition the jaw into a more comfortable and functional position. They are typically used to treat temporomandibular joint (TMJ) disorders and help alleviate the associated pain and discomfort.

Stabilization splints

Stabilization splints, sometimes referred to as flat plane splints, are designed to provide a stable and even surface for the teeth to contact when the jaw is closed. They help distribute the force of the bite evenly across the teeth, reducing the risk of damage and wear. These splints are often used to treat bruxism, TMJ disorders, and other issues related to an uneven bite.

The meaning of “full arch” in the context of occlusal guards

In the context of occlusal guards, a “full arch” refers to a guard that covers all of the teeth in one dental arch, either the upper or lower jaw. Full arch guards provide comprehensive protection for the entire set of teeth, ensuring that the force of the bite is distributed evenly and minimizing the risk of damage or wear.

The alternatives offer partial coverage. You can get some that are targeted at the front teeth, or at the back teeth. My personal preference to date has been partial guards as they are more comfortable.

In conclusion

Dentistry is a field filled with various terms and nomenclature, and this can sometimes make understanding the different types of occlusal guards and night guards confusing. However, it’s important to recognize that despite the diverse terminology, these devices ultimately serve a similar purpose: protecting the teeth and jaw from damage and discomfort caused by improper occlusion, grinding, clenching, or other issues. By understanding the various names and types of occlusal guards, you can make an informed decision about which device is right for your specific needs. Once you have it, make sure you clean it properly!
