Night guards create a barrier between the upper and lower teeth, preventing excessive wear, jaw pain, and other related problems.

2. Mouthguards

Mouthguards are protective appliances used during sports or physical activities to prevent dental injuries. They are typically made from a soft, flexible material that absorbs impact and cushions the teeth and gums. Custom-made mouthguards offer superior protection and a better fit compared to generic, over-the-counter options.

3. Snoring Appliances

Snoring appliances, also known as mandibular advancement devices, are used to alleviate snoring and mild to moderate obstructive sleep apnea. These appliances reposition the lower jaw and tongue to improve airflow and reduce snoring. Snoring appliances are custom-fitted to ensure optimal comfort and effectiveness.

4. Implant-Supported Prosthetics

Implant-supported prosthetics are dental appliances that are anchored to dental implants, which are titanium posts surgically placed into the jawbone. These appliances are used to replace missing teeth and provide a stable and durable solution. Implant-supported crowns, bridges, and dentures offer exceptional functionality and aesthetics, closely resembling natural teeth. They not only restore the ability to chew and speak but also stimulate the jawbone, preventing bone loss.

5. Veneers

Veneers are thin, custom-made shells that are bonded to the front surface of the teeth. They are primarily used for cosmetic purposes to improve the appearance of teeth that are discolored, chipped, or misshapen. Veneers are made from porcelain or composite resin materials and are designed to match the natural color and shape of the teeth. They provide a natural-looking and long-lasting solution for enhancing the smile.

6. Inlays and Onlays

Inlays and onlays are indirect dental restorations used to repair damaged or decayed teeth. They are an alternative to traditional fillings and offer a more conservative approach. Inlays are used when the restoration is confined to the grooves between the cusps of the tooth, while onlays are used when the restoration extends to cover one or more cusps. These restorations are custom-made in a dental lab and are fabricated from materials such as porcelain, composite resin, or gold. Inlays and onlays provide strength and durability while preserving more of the natural tooth structure compared to traditional fillings.

7. Sleep Apnea Appliances

Sleep apnea appliances, also known as oral appliances, are used in the treatment of obstructive sleep apnea. These appliances are custom-made and worn during sleep to reposition the jaw and keep the airway open, preventing episodes of apnea and snoring. Sleep apnea appliances offer a non-invasive alternative to continuous positive airway pressure (CPAP) machines and are more comfortable for many patients.

8. Surgical Guides

Surgical guides are precise and custom-made tools used in dental implant surgeries. They are created based on digital imaging data and aid dentists in accurately placing dental implants in the jawbone. Surgical guides enhance the efficiency and accuracy of the implant placement process, minimizing the risk of complications and ensuring optimal results.

9. Bite Splints

Bite splints, also known as occlusal splints or bite guards, are dental appliances used to address issues related to temporomandibular joint disorder (TMJ). These appliances help alleviate jaw pain, headaches, and other symptoms associated with teeth grinding, clenching, or misalignment of the jaw. Bite splints are custom-made to fit the patient’s bite and provide stability and relief from discomfort.

10. Wax-ups

Wax-ups are diagnostic models made from wax to help dentists plan and visualize restorative dental treatments. They are created based on impressions of the patient’s teeth and provide a three-dimensional representation of the planned dental restoration. Wax-ups allow both dentists and patients to preview the final result and make any necessary modifications before proceeding with the actual treatment.
