The 3Shape TRIOS 3D Scanner- Quick, Convenient Intraoral Imaging

At the dental gallery, we are always looking at ways of providing our patients with the highest quality and most convenient dental experience possible. For this reason, we have invested in the latest 3Shape TRIOS 3D Scanner at our Point Cook practice.

This small hand-held scanning tool and camera conveniently and comfortably scans the inside of your mouth while you are sitting in the dental chair. We can quickly produce accurate high resolution images of your teeth, palate and gums, then email the “images” to any lab for making aligners, retainers, dental implants, orthodontic appliances, night guards, sleep apnoea appliances, crowns and bridges.

Traditionally, dental impressions can be messy, uncomfortable for some people, cause gagging and can leave a bad taste in your mouth.

People are often impressed by the speed at which it scans the surface of the teeth and gums and displays an enlarged, realistic portrayal of all sides and angles of the teeth and gums. The result is an incredibly detailed digital impression that shows an enlarged version of what the dentist sees during an examination.

What Happens During a 3Shape TRIOS Scan?

The 3Shape TRIOS scanner is used while you are seated comfortably in a chair.
This hand-held scanner means that you do not need to hold your mouth open for extended periods of time as we can now take a few quick scans, and then look at the digital images on the display screen.

Advantages of the 3Shape TRIOS 3D Scanner

The 3Shape TRIOS 3D Scanner offers several benefits for our patients:

  • No need for traditional impressions.
  • Digital documentation: The 3Shape TRIOS instantly creates accurate, three-dimensional images that can be used for treatment planning.
  • Delivers no radiation.
  • Enhances Patient Communication. Your dentist can show you an enlarged image of your teeth and gum tissue and show any issues as clearly as if you were looking right into your own mouth.
  • Scans can be immediately sent to labs to begin the fabrication process.
  • Fewer appointments needed.
  • Fewer “remakes” due to the incredible accuracy of the scans.
  • Digital scanning is less intimidating for small children who may be scared or gag with traditional impression taking.
  • The scanner also uses a Real Colour and a Colour Matching feature that shows your mouth in natural colour thus making it easier plan proper treatment.
  • The colour matching feature improves the accuracy of matching crowns or veneers to your own teeth.

We look forward to introducing this new scanner into our office and creating an exceptional dental experience for you.

Why mouth breathing is bad for your health?

Why mouth breathing is bad for your health?

At the dental gallery we routinely screen for correct breathing and tongue position during our regular 6-monthly preventative examinations

The nose is best suited for breathing because it warms, humidifies and filters the air to prevent bacteria and particles entering the lungs. Mouth breathing leads to chronic irritation of the airway and can result in enlarged adenoids and tonsils in children.

There are many research studies describing the bad health consequences of mouth breathing.

Here are a few reasons why it is bad to mouth breathe.

Less production of nitric oxide

Nitric oxide is a gas that dilates (makes larger) blood vessels in the body and as a result increases oxygen uptake by the lungs. This gas is made in the sinuses. By breathing through your mouth, you’re missing out on production of this gas and also about 10 to 20% of additional oxygen uptake. As a result, you can compensate by breathing a bit faster and breathing off carbon dioxide. This can cause your carbon dioxide levels to drop, raising blood pH levels, and preventing oxygen from being released as easily to your body’s tissues.

It can cause crooked teeth

Breathing through your mouth prevents your face and jaw from developing properly. Inadequate jaw development can lead to crowding of your teeth and even narrowing of the upper airway. For children, one of the biggest causes of teeth crowding is habitually breathing through the mouth rather than the nose.

One extreme example is often referred to as “Adenoid Facies”, which results in an open mouth and forward head posture, long, narrow face, high arched hard palate, recessed lower jaw, and chronic nasal congestion. Having a smaller jaw can make you much more susceptible to future sleep-related breathing disorders.

It can lead to dental cavities

Mouth breathing leads to you having less saliva and a dry mouth. Saliva reduces acid levels, and can help to prevent plaque build-up. Mouth breathing can also cause you to have bad breath.

Mouth breathing can cause your tongue to fall backwards in your mouth

Ever wondered why it’s harder for you to breathe when lying down in a dentist’s chair with your mouth wide open? Opening your mouth causes your tongue to fall back, preventing proper breathing and in severe cases can obstruct the airway. For adults, the changes to the airway introduced by mouth-breathing while sleeping can give rise to snoring and sleep apnoea.

Concerned? Here are some signs of mouth breathing:

  • Dry lips
  • Having an open mouth posture
  • Dry mouth with inflamed gums
  • A long and narrow face
  • Narrow high arched palate
  • Crowded teeth or lack of spacing between baby teeth
  • Enlarged tonsils
  • Having a forward head posture

Some Common causes of mouth-breathing are:

  • Allergies
  • Chronic colds and sinus infections
  • Enlarged adenoids and/or tonsils
  • Nasal polyps
  • Deviated nasal septum

So what can be done to address mouth-breathing?

At the dental gallery we take an integrative approach to mouth breathing and work with Ear Nose and Throat (ENT) specialists and medical professionals to address the causes. This includes:

  • Airway assessment with an ENT specialist
  • Assessment and management of chronic allergies and infections
  • Breathing retraining

Targeted dental treatment:
In children we can expand the upper jaw and this can allow the tongue to sit properly on the palate and correct teeth crowding.
In some cases the lower jaw can also be brought forward to improve the airway.
In mouth breathing adults, we can bring the lower jaw forward with a mandibular advancement splint.

Poor Memory has been shown to be related to poor sleep or upper airway resistance syndrome

Poor Memory has been shown to be related to poor sleep or upper airway resistance syndrome

Recent clinical evidence suggests that women with sleep disordered breathing may experience different symptoms to men. A recent study from UCLA which reviewed the brain scans and medical notes of women with sleep apnoea found thinning of the brain structure (frontal cerebral cortex), the part of the brain responsible for higher cognitive functioning like mental processing and memory.  The study was by Professor Paul Macy from UCLA and he states “Because women report different symptoms, they tend to be misdiagnosed…. Early detection and treatment is the best way to protect against damage to the brain and other organs”.

Women are more likely to experience upper airway resistance syndrome UARS and this can cause them to experience daytime fatigue, feeling groggy, lack of motivation to do anything, poor focus, concentration problems, bruxism or grinding of teeth, cold feet and hands, low mood and depression.

This study builds on other research that sleep disordered breathing is a spectrum – ranging from sleep apnoea to upper airway resistance syndrome (UARS).  Obstructive sleep apnoea is a well-known sleep related breathing condition where there is repetitive stopping in breathing during sleep, due to collapse of the tissues of the throat. Unlike sleep apnoea where you have an obstruction causing an apnoea or cessation of breathing for 10 seconds and then an arousal or waking up, UARS patients typically have mostly partial obstructions and increased effort of breathing and then arousals or waking up. Patients with UARS do not actually have the 10 seconds of cessation of breathing but are still doing the same harm to their bodies as those with sleep apnoea.

Patients will UARS have some form of fatigue, most will say they are “light sleepers,” and almost invariably, they don’t like to sleep on their backs.  Some people attribute their poor quality sleep to insomnia, stress or working too much. Due to repetitive arousals at night, especially during the deeper levels of sleep, one is unable to get the required deep, restorative sleep that one needs to wake feeling refreshed in the morning.

In most cases, the cause is due to collapse of the tongue and the muscles of the airway. There are many reasons for the tongue and soft tissues to cause obstruction including being too large/floppy or if you are overweight. But once the obstruction occurs, the only thing you can do is to wake up and stop yourself from suffocating.

Due to repetitive arousals, your body is under a chronic state of low-grade stress – or what is referred to as the “flight response”. This is akin to when you’re frightened or running away from something. Your heart rate and blood pressure go up, your vision and hearing become very sensitive, and all your blood flow and energy is ready for a fight. As a result, blood gets shunted away from your gastrointestinal system to the heart muscles, this can lead to chronic diarrhoea, constipation, indigestion, acid reflux or bloating. In addition we know that stress can worsen acid production in the stomach.  Many people with UARS also have laryngopharyngeal reflux which is different to gastro-esophageal reflux disease.

People with laryngopharyngeal reflux do not feel heartburn but can complain of  chronic throat clearing, hoarseness, cough, postnasal drip, ear or throat pain, a lump in the throat, difficulty swallowing, tightness or pain with swallowing. Once the stomach acid gets into the throat it can enter the lungs causing or aggravating asthma or bronchitis. Acid can even get into the nose and ears causing or aggravating nasal congestion, sinus or ear infection.

Another study showed that about 23% of people with UARS have low-blood pressure. In addition, these people feel dizzy or lightheaded which is worse when they stand up too soon.  Even if their blood pressure is normal, some may still be prone to bouts of dizziness or light-headedness.

Tension headaches and classic migraine can occur frequently in people in UARS along with TMJ (temporo-mandibular joint) problems, which is due to grinding and/or clenching of their teeth. TMJ pain can be felt in the ear and many people think they have ear pain, as well as headaches along the side of your head, and teeth grinding can wear down your teeth or lead to having cracked teeth.

Some people can also have chronic or recurrent sinus pain, pressure or infections. Frequently, patients present to their doctor with frequent and recurrent sinus infections and are given antibiotics (which only help temporarily). In many cases, migraines can also masquerade as a sinus headache without the classic symptoms.

Depression, anxiety or attention deficit problems can be also seen in people with UARS. Multiple arousals and the fact you don’t sleep deeply, has been shown to cause your body to produce increased levels of cortisol. Cortisol (is a hormone that) makes you eat more and put on weight. It also lowers your body’s immune system to fight infections and can lead to insulin resistance, and eventually diabetes.

It seems that UARS symptoms can be aggravated by small changes in the person’s life. Gaining a small amount of weight, even 2-5kg, can aggravate the symptoms which go away once the body adjusts and accommodates to the increased weight it has to carry. A bad cold or respiratory tract infection that causes swelling and narrowing of the upper airway can also aggravate these symptoms. Pregnancy is another situation where this can occur.

In most cases the treatment of UARS is like sleep apnoea. The options are trying to improve you nasal breathing, dental appliances, myofunctional therapy, CPAP, or surgery, as a last resort. A mandibular advance splint (dental device) that pulls the lower jaw forward, similar to one used for snorers and in sleep apnoea patients can help. By pulling the jaw forward, it also pulls the tongue forward, creates tone in the muscles of the airway which can lead to an improvement in the size of the airway.
