Custom Fabricated Mouthguards

A custom-fabricated nightguard is a dental appliance specifically molded to fit the unique contours of an individual's upper or lower teeth. Its primary purpose is to protect teeth and the temporomandibular joint from the effects of bruxism (teeth grinding or clenching) and other occlusal or temporomandibular disorders.

Fabrication Process

Impression Taking: The process typically begins with a dentist taking an impression or mold of a patient's teeth using dental putty or through a digital scan.

Lab Crafting: This impression is then sent to a dental laboratory where technicians use it to craft a night guard that fits the patient's teeth perfectly.

Material Selection: Nightguards can be made from various materials, but they are commonly fabricated from durable, clear acrylics or other specialized plastics.

Features

Tailored Fit: Unlike over-the-counter nightguards, custom-fabricated variants offer a snug and comfortable fit, ensuring they stay in place throughout the night.

Thickness Variability: Depending on the severity of the patient's bruxism or specific needs, the nightguard's thickness can be adjusted.

Longevity: Due to their custom fit and quality materials, these nightguards tend to last longer than their store-bought counterparts.

Benefits

Protection: They effectively protect teeth from wear and potential chipping or breaking caused by grinding.

Comfort: Their custom-fit ensures they're more comfortable than one-size-fits-all solutions.

TMJ Relief: For those suffering from TMJ disorders, nightguards can alleviate some of the pressure and pain associated with jaw clenching.

Sleep Improvement: Reducing the discomfort and potential pain from teeth grinding can lead to a better night's sleep.

Considerations

Maintenance: Nightguards need to be cleaned regularly to maintain hygiene. It's recommended to rinse them every morning and occasionally give them a deeper clean with appropriate cleaners.

Regular Checks: It's advisable for patients to have their nightguards checked during their regular dental visits to ensure they're still in good condition and fit correctly.

Custom-fabricated night guards offer a superior solution to generic, over-the-counter options. By providing a tailored fit, they not only ensure better protection against the harmful effects of teeth grinding but also offer enhanced comfort. For individuals with pronounced bruxism or related disorders, investing in a custom night guard can significantly improve their oral health and overall sleep quality.

Custom Fabricated Surgical Stents

A custom-fabricated surgical stent is a specialized medical device used to guide the placement of dental implants, ensuring accurate positioning and angulation during surgical procedures. These stents are precisely tailored to an individual's anatomy, offering dentists a roadmap for implant placement based on pre-surgical planning.
