851 - Extraoral appliance

ADA schedule description:

This item describes a number of appliances worn extraorally. Some appliances are worn to correct mandibular protrusion and are not attached directly to the dentition. Other appliances in this category are attached to the dentition by either full or partial banding. Most of these appliances have a harness that is passed behind the head or to the front of the face to provide stabilisation for the forces applied. They are usually worn for a limited time each day.

When is item code 851 (Extraoral appliance) typically used?

An extraoral appliance is necessary to apply external forces to correct jaw alignment or tooth positioning. This procedure involves fabricating and fitting an appliance using materials like acrylic or metal to exert controlled forces on the jaws or teeth. Proper alignment ensures the restoration remains functional and comfortable, improving jaw relationships and enhancing function and aesthetics. Extraoral appliances are particularly useful for patients with severe malocclusion or skeletal discrepancies.

How does item code 851 (Extraoral appliance) typically benefit the patient?

Improving jaw relationships enhances function and aesthetics, enabling the patient to enjoy a healthy and attractive smile. By addressing alignment issues, the procedure prevents complications such as discomfort or excessive force, ensuring the prosthesis remains stable and durable over time. Additionally, it enhances the durability of the restoration, ensuring it remains functional and aesthetically pleasing over time. By addressing structural issues, the procedure prevents complications such as discomfort or failure, ensuring long-term success.

What is an oral and maxillofacial surgeon's perspective on item code 851 (Extraoral appliance)?

Ensure proper fit and alignment to avoid excessive force or discomfort. Use advanced techniques to ensure a strong and durable bond, reducing the risk of failure. Verify the fit and margins of the appliance to ensure it does not interfere with the patient’s comfort or movement. Educate the patient on proper care and maintenance of the appliance, emphasizing the importance of regular cleaning and follow-ups.

Miscellaneous

The miscellaneous category covers unique or specialized treatments that don’t fall under other specific categories. Examples include custom mouthguards, occlusal guards for bruxism (teeth grinding), sleep apnea appliances, and other patient-specific devices designed to improve comfort, function, or aesthetics.

General Services

General dental services encompass routine care and minor procedures essential for maintaining overall oral health. This includes fillings, extractions, emergency treatments, and basic restorations. These services address common issues like cavities, broken teeth, and gum irritation, ensuring patients maintain functional and healthy smiles.

Orthodontics

Orthodontic treatments are focused on correcting misaligned teeth and jaws to improve both function and appearance. Procedures typically involve braces, clear aligners (e.g., Invisalign), retainers, and other appliances that gradually shift teeth into proper alignment. Orthodontics not only enhances aesthetics but also improves bite functionality and reduces the risk of future dental problems.

Prosthodontics

Prosthodontic treatments involve replacing missing teeth and restoring damaged oral structures using artificial substitutes. Procedures include crowns, bridges, dentures, and dental implants. The goal is to restore functionality, improve speech and chewing ability, and enhance the aesthetic appeal of the smile.

Restorative Services

Restorative services focus on repairing damaged or decayed teeth to restore their form, function, and strength. Common treatments include fillings, inlays/onlays, veneers, and bonding. These procedures aim to prolong the life of natural teeth and ensure they remain functional and visually appealing.

Endodontics

Endodontic treatments focus on the inner part of the tooth, particularly the pulp and root canals. Common procedures include root canal therapy, which removes infected or damaged tissue from inside the tooth, and apicoectomy (surgical removal of the root tip). The goal is to preserve natural teeth while alleviating pain caused by infection or inflammation.

Oral Surgery

Oral surgery involves surgical procedures performed in or around the mouth and jaw. Treatments range from simple tooth extractions to more complex surgeries such as wisdom tooth removal, dental implant placement, bone grafting, and corrective jaw surgery. These procedures aim to restore function, alleviate pain, and enhance facial structure.

Periodontics

Periodontics deals with the prevention, diagnosis, and treatment of gum diseases and conditions affecting the supporting structures of the teeth. Services include scaling and root planing (deep cleaning), gum grafts, pocket reduction surgery, and regenerative therapies. The primary objective is to prevent tooth loss and maintain healthy gums.

Preventive, Prophylactic and Bleaching Services

This category emphasizes preventive care to maintain optimal oral health and prevent future problems. It includes professional cleanings (prophylaxis), fluoride treatments, sealants, and patient education on proper hygiene practices. Additionally, bleaching services (teeth whitening) are offered to enhance the cosmetic appearance of teeth safely and effectively.

Diagnostic Services

Diagnostic services involve procedures aimed at identifying and assessing oral health conditions. These include clinical examinations, X-rays, digital imaging, biopsies, and other diagnostic tools that help in detecting diseases or abnormalities early on, allowing for timely intervention.

Dr Nu was absolutely amazing. Last time I used CPAP in 20 years was the night before my surgery. She is an amazing surgeon, cured me of sleep apnea, and I feel amazing. Best thing I ever did.

My experience, from start to finish, was as pleasant as a wisdom tooth extraction could be! I had all four wisdom teeth removed under general anesthetic, and Dr. Mehrnoosh Dastaran was absolutely delightful. She made me feel completely at ease throughout the process, despite my nerves leading up to the procedure. Her professionalism and reassuring demeanor truly made a world of difference. Additionally, Waverley Private Hospital was an excellent facility, making the entire experience even more seamless and comfortable.

I had an incredible experience with Nu and the team for lower jaw surgery and wisdom teeth removal. The whole process was smooth and Nu has such a kind and calming presence - she is so relaxed and it's hard to believe she's come straight from surgery most days.

I needed a few teeth out for my orthodontic treatment. Dr Nu Dastaran and her nurses Emma and Poppy did an amazing job. Completely painless. I opted to do it over 2 sessions. The offices are state-of-the-art and everyone at OMFS is friendly and welcoming. This is my 3rd time at OMFS and I have no idea what the 1 Star reviewers are talking about.
