The Smile Design and Space (SDS) concept

The Smile Design and Space (SDS) concept

Innovative full-mouth reconstruction to enhance oral health and biomechanics

Living life with a truly optimised smile is about more than just beautiful teeth. The Smile Design and Space (SDS) concept takes a broader view—considering your entire head anatomy, including jaw alignment, facial structure, and lip mobility—to achieve a harmonious balance of aesthetics, functionality, and health. This holistic approach integrates advanced dental techniques to craft smiles that are not only stunning and natural but also built for lasting comfort and performance.

What is the SDS concept?

The SDS approach is about ensuring your anatomy has the space it needs where it matters most. This groundbreaking method optimises the vertical space between the upper and lower jaws when you bite. That space is known as vertical dimension of occlusion (VDO), and it is vital to proper oral function, long-term dental health, and overall comfort.

Unlike traditional tooth-centric methods which have a narrower focus, the SDS concept takes a facially driven treatment approach. It carefully evaluates the unique relationships between facial features, teeth, and jaw alignment to create a tailored plan that enhances aesthetics and functionality. By addressing the limitations of conventional VDO adjustments, the SDS concept minimises invasiveness while delivering exceptional, patient-specific results. This innovative method prioritises comfort, balance, and a natural appearance, offering a holistic solution for full-mouth restoration.

How does the SDS concept work?

The SDS concept follows a meticulous, structured approach that integrates precise assessments with advanced dental techniques, delivering consistently optimal results. Here’s how it works:

Evaluating the maxillary central incisors

The upper front teeth—or maxillary central incisors—are carefully assessed for their position and visibility in relation to the upper lip, both at rest and during a full smile. This step is crucial for determining the ideal incisal edge position, which significantly influences the harmony and natural appearance of the smile.

Considering lip mobility

Each patient’s lip mobility is analysed, as it impacts how much of the teeth and gums are visible when smiling. Special attention is given to patients with gingival exposure (a “gummy smile”) to ensure a balanced and aesthetically pleasing result.

Strategic adjustments to the bite height

The SDS concept uses a systematic formula that accounts for dental relationships, wear patterns, and individual needs to determine precise alterations to the vertical dimension of occlusion. These adjustments are carefully calibrated to enhance both the functional dynamics of the bite and the overall aesthetic outcome.

Integrating these steps, the SDS concept delivers a personalised approach to full-mouth reconstruction that emphasises harmony, functionality, and minimal invasiveness. This meticulous process ensures lasting results that blend seamlessly with each patient’s unique features.

Benefits of the SDS concept

The SDS concept provides several compelling advantages compared to traditional methods of full-mouth reconstruction:

Minimal invasiveness: By preserving as much natural tooth structure as possible, the SDS concept reduces the need for extensive preparation or irreversible changes, ensuring a conservative yet effective treatment approach.

Enhanced aesthetics: The SDS concept integrates dental and facial features to create a balanced, natural-looking smile that complements the patient’s unique appearance.

Improved functionality: Proper alignment and bite are prioritised, reducing the risk of jaw discomfort, uneven wear, or compromised chewing efficiency.

Predictable outcomes: The systematic and patient-focused methodology enhances the reliability of the treatment, leading to consistent, high-quality results and a higher rate of long-term success.

Why is the SDS concept significant?

The SDS concept represents a paradigm shift in dental care, emphasising highly individualised treatment plans. By tailoring the approach to each patient’s unique aesthetic and functional needs, the SDS concept ensures outcomes that are not only visually stunning but also durable and comfortable over the long term. This focus on personalisation enhances patient satisfaction and the overall success of full-mouth reconstructions.

Who can benefit from the SDS concept?

The SDS concept is particularly beneficial for individuals considering full-mouth reconstruction to address complex dental issues such as:

Severe tooth wear: Restoring the original structure and function of heavily worn teeth.

Misalignment: Correcting bite issues to improve chewing efficiency and comfort.

Gummy smile: Balancing the visibility of teeth and gums for an aesthetically pleasing result.

The SDS concept combines aesthetics with functionality, providing a comprehensive solution for patients seeking transformative dental care. This innovative approach makes it possible to achieve a healthy, balanced, and naturally beautiful smile tailored to each individual’s unique characteristics.

Exceptional whole-mouth restorations

The SDS concept goes far beyond the basics of dentistry to provide precise, lasting results for your entire oral anatomy, including jaw, teeth, gums and lips. This powerful framework balances aesthetics with functionality, to create customised treatment plans that truly meet each patient’s needs in a genuinely comprehensive manner.

For those undergoing full-mouth reconstruction, achieving a beautiful and healthy smile is non-negotiable. For these patients, the SDS approach delivers predictable outcomes with confidence. Support your long-term oral health and optimise your bite biomechanics by asking your dental professional about the SDS concept.

Missing tooth solutions for seniors

Missing tooth solutions for seniors

As we get older, we begin to deeply appreciate that maintaining our oral health is crucial to our enjoyment of everyday life. Tooth loss demoralise us in our efforts, no matter whether it is the result of tooth decay, gum disease or dental trauma. In severe cases, a tooth may require extraction if it can’t be repaired through dental fillings, crowns or other restorations. However, losing a tooth does not need to have a negative impact on life. What you do about it makes all the difference.

In this blog, we’ll discuss the effects of missing teeth and the common tooth replacement options for seniors.

Australian seniors are missing over 13 teeth on average

In 2017–2018, adults aged 65 and over had an average of 13.7 missing teeth. Additionally, the percentage of adults with complete tooth loss rose with age, from 8.1% in the 55–74 age group to 21% among those aged 75 and over. (National Study of Adult Oral Health 2017-2018)

What are the effects of missing teeth?

The impact of missing teeth goes beyond just the physical appearance of your smile. Here are some of the many adverse primary effects of missing teeth:

Chewing and digestion problems:

Missing teeth can make it difficult to properly chew food, resulting in improper digestion. Poorly chewed food can strain the digestive system and reduce nutrient absorption, potentially leading to nutritional deficiencies.

Speech impairments:

Teeth play a crucial role in the formation of speech sounds and words. The absence of teeth, particularly the front teeth, can alter speech patterns, resulting in difficulties with pronunciation and communication.

Altered facial appearance:

Your teeth provide facial structure. When teeth are missing, the jawbone may begin to deteriorate, causing facial shape changes and a sunken appearance.

Bone loss:

The roots of your teeth stimulate the jawbone, preserving its strength and density. When teeth are missing, this stimulation decreases, resulting in gradual bone loss. This can affect your facial structure and make future dental implant placement more difficult.

Adjacent teeth shifting:

When a tooth is missing, the teeth next to it may start to shift or tilt into the empty space. This can lead to misalignment, bite problems and difficulty correctly cleaning the teeth.

Gum and periodontal issues:

Due to exposed areas where teeth are missing, the gums can become more susceptible to irritation and infection. These areas are particularly prone to developing gum disease and periodontal problems.

Self-esteem and confidence:

Missing teeth can result in self-consciousness, lowering your confidence and self-esteem. You may feel awkward when you smile or interact with others.

Joint and bite issues:

Missing teeth can change the proper alignment of your bite, causing problems like temporomandibular joint (TMJ) disorders, headaches and jaw pain.

Oral health complications:

Untreated missing teeth can result in a progression of oral health issues, including gum disease, tooth decay and additional tooth loss. It can lead to a deteriorating state of oral health.

Increased risk of tooth decay:

The presence of gaps between teeth may trap food particles and make cleaning more difficult. This increases the risk of tooth decay and cavities in neighbouring teeth.

Limited food choices:

Certain foods, especially those that require significant chewing, may be difficult to consume if you have missing teeth. This may result in a diet with less variety and possible nutritional deficiencies.

Aesthetic concerns:

While this is generally the most visible effect, the appearance of missing teeth can have an impact on your self-image and how others view you.

It is essential to replace missing teeth to prevent future dental problems and preserve oral health, overall well-being and quality of life.

What are the solutions for missing teeth?

Dentures

Traditional removable option

Dentures have been a popular option for seniors with missing teeth for decades. There are two types of removable replacements: full dentures for those with complete tooth loss and partial dentures for those missing only a few teeth. The advancements in dentistry have resulted in dentures that are more functional and aesthetically pleasing, as well as more comfortable and lifelike.

Dental bridges

Bridging the gap

Seniors often utilise dental bridges as a fixed solution when they are missing one or more adjacent teeth. These artificial teeth are attached to the natural teeth on either side of the gap. Bridges restore proper chewing function and preserve the alignment of the surrounding teeth.

Implant-supported dentures

Enhanced stability

Implant-supported dentures are the optimal solution for seniors desiring the benefits of both dentures and dental implants. These dentures are attached securely to dental implants, ensuring their stability while eating and speaking. This option combines the convenience of dentures with the durability of implants.

Dental Implants

Long-lasting restoration

Dental implants can provide permanent natural-looking replacements for missing teeth. These titanium posts are surgically implanted into the jawbone to serve as a stable foundation for prosthetic teeth. Dental implants restore chewing function and stimulate the jawbone to prevent bone loss over time, which increases in importance as we age.

Bone augmentation

Strengthening the foundation

Some seniors may experience bone loss in the jaw due to missing teeth over time. Bone augmentation, also known as bone grafting, is a procedure that enhances the density of the jawbone. This procedure creates a solid base for dental implants and ensures their long-term success.

Regular dental check-ups

Prevention and maintenance

Prevention is essential for maintaining oral health, particularly for seniors. Regular dental check-ups allow for early detection of potential problems and provide the opportunity to discuss tooth replacement options with your dentist. Your dentist can assist in customising a treatment plan to your specific requirements and desires.
