Stronger smiles faster with 3D printed inlays and onlays

You might be familiar with dentistry history, in which fixing moderately damaged teeth usually meant removing a lot of healthy tooth structures to make room for a crown. This approach, while effective, wasn’t ideal for preserving as much of the natural tooth as possible. In some clinics and certain cases, that older approach continues to be used, but there’s a better restoration method now available in modern clinics: 3D printed inlays and onlays. These highly precise restorations fit into or onto the damaged part of the tooth, allowing for a more conservative approach that saves more of your natural tooth.

With the introduction of digital dentistry and 3D printing, inlays and onlays have become even more efficient and precise. This technology allows dentists to create custom-fit restorations that perfectly match your tooth’s unique shape and structure, resulting in a faster, stronger, and more natural-looking smile.

What are inlays and onlays?

Inlays and onlays are tooth restorations used to repair teeth with moderate damage, such as large cavities, cracks, or fractures. Unlike crowns, which completely cover the tooth, inlays and onlays are more conservative. Here’s a breakdown of their key features:

Function: Inlays resemble fillings but are more substantial and custom-crafted to fit precisely within the tooth’s cusp (pointed chewing surface). Onlays, on the other hand, cover a larger portion of the tooth structure, extending beyond the cusp onto one or more sides.

Material: Inlays and onlays are typically made from strong, durable materials like porcelain or composite resin. These materials are chosen for their ability to withstand chewing forces and resist wear and tear.

Benefits: There are several advantages to choosing inlays and onlays over traditional restorations:

Preservation of tooth structure: By only replacing the damaged portion of the tooth, inlays and onlays conserve more of the natural tooth structure. This can benefit the long-term health of the tooth and surrounding bone.

Strength and longevity: The materials used in inlays and onlays are highly durable and can last for many years with proper care.

Improved aesthetics: Inlays and onlays are custom-designed to match the colour and texture of your surrounding teeth, resulting in a natural and seamless appearance.

What’s good about 3D printed restorations?

Dental Restoration

Faster turnarounds and streamlined visits

Say goodbye to weeks of waiting! Traditional inlays and onlays involve sending impressions to a lab, leading to multiple appointments. 3D printing eliminates this wait. Dentists can now use digital scans and design software to create precise restorations right in their offices. This can potentially condense the entire process into a single visit, saving you valuable time and reducing the number of trips to the dentist.

Enhanced precision and potential for longer lifespan

3D printing boasts incredible accuracy, resulting in inlays and onlays that fit your teeth flawlessly. This precise fit minimises the risk of future problems like leakage or sensitivity, potentially leading to a longer lifespan for your restoration. Additionally, the improved fit can translate to a more comfortable chewing experience.

Convenience and comfort you can smile about

Patients choosing 3D-printed inlays and onlays benefit from a more convenient treatment journey. Fewer appointments are typically needed compared to traditional methods. Plus, ditching the uncomfortable physical impressions often used in traditional techniques translates to a more pleasant experience overall.

Natural look, long-lasting results

3D printed restorations are custom-made to perfectly match your surrounding teeth, ensuring a natural and aesthetically pleasing appearance. These restorations are not just beautiful, they’re built to last. The high-quality materials used in 3D printing contribute to the durability of the inlays and onlays, allowing you to enjoy a confident smile for years to come.

How 3D printed inlays and onlays are created

Creating 3D-printed inlays and onlays uses advanced digital dentistry technology to achieve precise and efficient dental restorations. Here’s how the process works:

Digital X-rays:

For optimal treatment planning, dentists usually rely on high-resolution digital X-rays. These detailed images allow them to see your tooth’s internal structure clearly, revealing any decay, fractures, or hidden problems. This information is crucial for creating a customised restoration plan that minimises tooth removal and ensures the best coverage for your tooth.

Intraoral scanning:

This handheld camera takes a well-defined, precise 3D digital impression of your prepared tooth and the surrounding area. It eliminates the need for messy traditional impressions and provides an accurate model for designing restorations.

3D printed Inlays and onlays CAD Software

Smile designing:

Using advanced smile modelling software like Medit CliniCAD or exocad, your dentist virtually designs the 3D model of your restorations. This software allows for precise adjustments to ensure a perfect fit within the prepared cavity. For the best possible outcome, factors like gap size and restoration thickness are tailored to your unique needs, promoting strength, aesthetics, and bite function.

3D printing:

Following the design of your ideal smile, your dentist will use biocompatible resin to 3D print your custom inlay or onlay. These resins, often ceramic-filled, are incredibly strong and designed to mimic your teeth’s natural look and feel. This translates to long-lasting restorations that blend seamlessly with your surrounding teeth, creating a natural and beautiful smile.

Support removal and polishing:

The temporary support structures used during printing will be removed using clippers or tweezers. Precise removal techniques ensure a smooth surface for the following polishing step. Once removed, the restorations are then polished to achieve a smooth, natural-looking surface that reflects light like your surrounding teeth.

Cleaning:

This phase typically involves an initial wash in isopropyl alcohol (IPA) to remove any residue, followed by alcohol spraying and meticulous cleaning with a micro brush. Compressed air drying ensures no moisture remains, which could impact the final result.

Post-curing in glycerine:

Your dentist may apply a thin layer of glycerine to prevent moisture absorption before final curing. Glycerine eliminates oxygen, allowing the resin to fully cure and reach its optimal strength.

Final curing:

Your restoration is placed inside a UV curing unit for final hardening, ensuring the inlay or onlay achieves maximum strength and durability.

3D printed Inlays and onlays

Characterising:

For exceptional aesthetics, pigments, stains, and textures can be applied to perfectly match the colour and surface characteristics of your natural teeth. UV light is used to ensure proper bonding and curing of the glaze and coats.

Mock-up wax-up:

A replica of your prepared tooth is used to verify the fit and function of the completed inlay or onlay. This mock-up step ensures the restoration integrates seamlessly into your mouth and functions properly before actual bonding.

Might 3D-printed inlays and onlays be right for you?

If you have a moderately damaged tooth that needs more than a simple filling but doesn’t require a full crown, 3D-printed inlays and onlays could be a suitable option. These restorations are designed to preserve as much of your natural tooth structure as possible. Here are some factors to consider:

The extent of damage: Inlays and onlays are ideal for teeth with moderate damage. If the damage is too extensive, a full crown might be necessary.

Preservation of tooth structure: Inlays and onlays are less invasive than crowns, meaning more of your natural tooth can be preserved.

Precision and fit: 3D-printed inlays and onlays offer high precision and a perfect fit, which can enhance the longevity and effectiveness of the restoration.

Consult your dentist: Your dentist will evaluate the damage’s extent and overall oral health to determine if inlays or onlays are the best option for you.

Save more of your smile to live your best life

3D printing is rapidly evolving in dentistry, offering exciting possibilities that give you better results and greater freedom. Efficient, personalised, and durable restorations are available faster than ever before! As this technology continues to advance, 3D-printed inlays and onlays are becoming an increasingly popular choice for those looking to maintain a healthy and beautiful smile.

Composite bonding / veneers / edge bonding – the conservative tooth repair solution

Composite bonding / veneers / edge bonding – the conservative tooth repair solution

by | Apr 27, 2022 | Cosmetic Dentistry, Dental Treatment, Oral Conditions and Issues

What is composite bonding?

Composite bonding, composite veneers or edge bonding are dental techniques used when your dentist applies a tooth-coloured resin to the full frontal surface or the edges (i.e. tips and sides) of the teeth. You can also receive composite bonding and composite veneers as parts of the same treatment plan.

What dental issues can composite bonding treat?

Composite bonding treatment is a really versatile, gentle and conservative dental treatment used to fix chipped teeth, close gaps, change the shape and size of teeth, and alter a tooth’s colour and shade.

Whether bonding is used over traditional veneers depends on what issues you have regarding your defective teeth. This includes what shape, size, shape and position you want in the final result. For example, if you have a few minor chips but are still happy with the shape and colour of your teeth, then composite edge bonding is a highly recommended treatment option.

However, if you’re looking to correct more complex issues such as the shape or size of teeth, alignment, and/or want them looking whiter, then covering the full surfaces of a tooth to build up a composite veneer may be recommended.

Composite bonding is getting more and more popular as a more affordable alternative to porcelain veneers. It’s also a more conservative and less invasive treatment that requires minimal preparation of your natural teeth and removal of tooth structure and enamel.

Are you suitable for composite bonding treatment?

Your suitability for composite bonding treatment is dependent on what results you want to achieve and how healthy your teeth are. These factors can only be assessed via a thorough oral examination in the dental chair.

During this examination, your dentist will assess your teeth, gums and bite. If you have any dental issues, such as tooth decay, cavities or gum disease, these oral conditions should be treated prior to commencing composite bonding treatment. Likewise, if you clench or grind your teeth, resolving these issues may be required before any cosmetic work can be done.

Additionally, if your teeth are misaligned, then you may need to have orthodontic treatment, such as braces or clear aligners such as Invisalign. If you don’t have your teeth straightened first, then your final results may be compromised in the long term. It’s also a recommended to complete a teeth whitening session before composite bonding or veneer treatment since the colour of the resin cannot be altered once cured.

White dental fillings – CEREC porcelain vs composite resin

White dental fillings – CEREC porcelain vs composite resin

by | Feb 4, 2022 | Cosmetic Dentistry, Dental Treatment, New Dental Technology

White fillings are a popular type of dental filling used to restore decayed teeth or cavities. Because they are available in a number of colour options, they can blend seamlessly with your affected tooth’s remaining structure and the surrounding teeth – as opposed to highly visible metal fillings. White fillings can also be used to change the shape and size of your teeth, which is especially beneficial in cases of damaged, worn or eroded teeth.

The difference between CEREC porcelain and composite resin fillings

Not all white fillings are the same. While different types of white fillings may look very similar, they come in two main options based on the filling material used – porcelain or composite resin. Glass Ionomer fillings (GIC) are another white filling option but are typically used in cases of child tooth decay, adult temporary fillings and sub-gingival fillings (below the gumline). The difference between porcelain and composite filling materials is like comparing apples to oranges. Porcelain fillings – also known as inlays, CEREC or ceramic restorations – are a lot harder and durable than “composite resin” fillings which are also referred to as plastic, resin or composite fillings.

Composite resin – the low-cost but less durable filling option

Composite fillings are definitely the least expensive filling option – but you get what you pay for. Despite the advantage of saving on your short term dental costs, composite fillings don’t have the same success rate as porcelain fillings. They need to be replaced after 5 or 6 years since they cannot withstand the pressures of heavy chewing over time. This may result in a higher risk of fractures and a breakage which means you may have to repair or replace them more often. Another problem with composite fillings is that they can shrink over time thus pulling away from and stressing the natural tooth structure walls surrounding the fillings.

So, not only can the filling fail but your remaining original tooth may fracture also. Additionally, once composite fillings start to contract, tooth decay can start to penetrate between the filling and original tooth structure and cause more oral issues. If left untreated, this can result in hidden decay, catastrophic failure and tooth loss. Lastly, colour integrity is also an issue since composites can fade or discolour and start standing out from the rest of your teeth.

CEREC porcelain fillings – the more natural looking and long-lasting filling

Porcelain fillings are a better and more stable long term filling solution. If they are CEREC fillings, these super-hard restorations are created using the latest 3D CAD-CAM dental technologies – for a perfect and very stable fit that lasts 15 years or more. When completed successfully, they can also support the remaining tooth structure and prevent further deterioration.

Since there is minimal wear and tear on porcelain fillings, there is less of a requirement to excavate and prep a tooth. This means you’ll be able to retain more of your natural tooth structure – to create a stronger foundation for your filling. CEREC fillings are more expensive without a doubt, but when you factor in the replacement expenses of composites over time, the cost differential is negligible.

Why do you need retainers after teeth straightening?

Why do you need retainers after teeth straightening?

Most people are unaware of the effects mouth breathing has on orthodontic treatment until after they get their teeth straightened or realigned. Whether they have received braces or Invisalign aligner treatment, a relapse usually occurs to some degree, even after a 100% successful realignment. In the event of a relapse – where the straightened teeth start to gradually shift back towards their original positions – retainers may need to be worn temporarily to allow supportive gum tissue more time to strengthen and stabilise realigned teeth. However, there is another potential risk factor that may be constantly forcing realigned teeth to shift back – how you breathe and your tongue posture.

The tongue – nature’s perfect retainer for straight teeth

Long before the availability of braces or aligner treatments to straighten teeth, nature provided the perfect “retainer” to ensure that your teeth develop and erupt evenly – your tongue. In opposition to the inward forces exerted by the cheek muscles (buccinators), your tongue provides an opposing lateral force that pushes the teeth out. When both forces are equally balanced at approximately 500 gm and your dental arches are well developed, your primary teeth should erupt evenly in all their proper positions during childhood.

How mouth breathing causes straightened teeth to shift back

If you are a mouth-breather – as opposed to a nasal-breather – your bottom jaw sits lower which results in low tongue posture. This leaves your upper jaw (maxilla) without the support and outward force required to counteract the cheek muscles’ inward forces. Without this counterbalancing effect, the inward force exertion causes the arches to narrow during development thus creating a narrow arch, less space for erupting teeth and misaligned or crowded teeth as a result. Now, when you jump forward in time to the teen or adult that has received orthodontic treatment, it is important to understand the very same oral forces that have caused teeth misalignment issues during development are probably still in play after treatment. 

Why do you need retainers after teeth straightening?

Orthotropic treatment can help minimise the need for retainers

While orthodontic treatment such as braces and aligners focuses on straightening teeth, orthotropic treatment focuses on rectifying breathing and postural habits that cause teeth to misalign in the first place. When children and teens receive orthotropic treatment, adopting new mouth and tongue postural habits can improve their oral development. This can result in better teeth alignment all the way into adulthood. However, just because you’re an adult receiving orthodontic treatment, it doesn’t mean you’ve missed out on all the benefits of orthotropics. By simply ensuring that you breathe through your nose, keep your mouth closed and position your tongue correctly on the palate of the mouth, you can help minimise the forces acting against your newly positioned and straightened teeth. This allows supportive ligaments to strengthen and stabilise teeth in their sockets sooner rather than later – and less time spent wearing retainers!

How aesthetic dentistry can give you a healthier smile makeover

How aesthetic dentistry can give you a healthier smile makeover

by | Aug 30, 2020 | Cosmetic Dentistry, Dental Treatment

To get a better idea of how aesthetic dentistry can improve oral health outcomes for cosmetic treatments, let’s take a look at a situation where a young adult with healthy teeth wants full veneers for purely cosmetic reasons. 

Why are veneers so popular among social media users?

Veneers have become a tremendously popular way to cover up stained, chipped, crooked, misaligned, misshapen or worn out teeth – mainly due to the growing obsession among social media users with having the perfect “selfie smile”. In situations where patients have severely damaged or malformed teeth that cannot be whitened, veneers are a great way to improve your smile and strengthen weakened teeth. But what if you already have healthy teeth but think that you want a full set of veneers for that perfect selfie smile?

The disadvantages of getting veneers for purely cosmetic reasons

Typically, a healthy patient wanting veneers for cosmetic reasons prefers to take the quickest route to achieve the perfect smile. Then presto, they have an instant perfect smile. However, the trade-off that a patient makes for a dozen bright white porcelain veneers over their own healthy teeth may include:

  • Losing natural, healthy teeth structure unnecessarily during prep,
  • The need to replace veneers up to a few times in their lifetime,
  • A higher risk of future oral health complications, and
  • Ongoing follow-up dental treatment costs that may be expensive.

Aesthetic dental veneer options for healthy teeth and gums

A dentist following aesthetic dental principles might recommend a more comprehensive treatment plan to avoid or minimise the impact of these potential oral issues. For example, an aesthetic dentist might recommend a “compromise” treatment resulting in the need for less invasive prep and veneers. This is made possible by straightening a patient’s teeth first via orthodontics. The thought of undergoing orthodontic treatment might put off a lot of patients who can’t wait. However, short-term aligners, such as Invisalign clear aligners, have been developed specifically for the cosmetic industry. Invisalign aligners can be used to straighten the front teeth in as little as 14 weeks. This is a much shorter time frame compared to standard orthodontics. Once a patient realises that this dental option is available, they soon realise they can achieve the smile they desire, along with better long term oral health and functional benefits – just by taking that extra step. They can still get their veneers but will only need to be fitted with minimal veneers involving less invasive prep. 

How aesthetic dentistry can give you a healthier smile makeover

The veneer-free path to a beautiful smile

An aesthetic dentist might also be able to persuade the patient to refuse veneers altogether. As a patient’s treatment progresses step-by-step, their perspective and decision-making process change. They will be able to see how close the combination of orthodontic treatment and teeth whitening has got them to their perfect smile. From there, all that might be required to complete the smile makeover is composite edge bonding to perfect the teeth’s shape. The aesthetic dental approach in this instance has just saved the patient’s natural teeth from an otherwise invasive smile makeover treatment. No tooth structure or gum tissue has been removed. Instead, they have a beautiful, healthy smile with their very own natural teeth!
