Gum disease, also known as periodontal disease, is an infection of the gums and tissues around the teeth that can lead to tooth loss if left untreated and is caused by the buildup of plaque and bacteria in the mouth. Losing your teeth can have a dramatic impact on your oral health, how you look and your self-confidence. Even a single missing tooth can be very noticeable when you open your mouth to speak, eat or smile. Over time, the gap itself can alter your jaw and face structure, further changing how you look and impacting your self-esteem.

With missing or damaged teeth, the type of teeth replacement can make all the difference to how you look and feel afterwards. While removable dentures solve the problem to some extent, they can still be uncomfortable and don’t provide the same biting force as natural teeth. The result is that while you might look more like the old you, you still won’t be able to eat and talk like you used to.


If you are missing all of your teeth, all-on-4 dental implants are highly recommended. But what do you need to know before getting full-mouth tooth replacements? Understanding all-on-4 starts with understanding how it works and its benefits.

All on 4 is essentially a full arch implant restoration system that replaces teeth. The procedure uses four titanium metal dental implants, two at the front section of the jaw bone and two posteriorly tilted implants for increased support at the back. Once these implants are surgically placed into the jawbone, a bridge is attached, allowing you to leave the clinic with a fully functional set of permanent replacement teeth. The treatment promises patients an immediate improvement in oral aesthetics and function.

Kiss Goodbye to Poorly Fitted Dentures

We often see patients with dentures at our Sydney clinic in Sutherland Shire who are looking for a more permanent solution for tooth replacement. They want an affordable solution that fixes their problem so they can eat comfortably without worrying their dentures will slip out of place. The All on 4 technique is the ideal solution for patients who do not want to compromise their lifestyle due to missing teeth.

The reason All on 4 is so highly recommended is due to its unique ability to provide full mouth restoration within 24-48 hours. Unlike other tooth replacement options such as traditional implants that take months and multiple visits to complete, All on 4 dental implants minimise wait times and are effective alternatives for people with weaker or thinner jawbones.


New Smile Within 24 Hours

Though both options are suitable for restoring teeth, there are notable differences between All on 4 and traditional dental implants. To begin, unlike traditional implants which require multiple appointments over several months for implant placement and healing time, All on 4 can take only one day to place. Once the surgical insertion sites have healed, acrylic or titanium fixed bridges are secured onto the implants, providing long-term benefits such as greater oral functionality, and improved speech and smile appearance.

Fewer Implants   

One significant difference is the number of implants required in All on 4. Whereas standard-implant procedures need anywhere from eight to twelve screws per arch (one screw per tooth), All on 4 uses just four implants in total: two upright screws at the front and two tilted screws at the back of each arch to distribute greater bite forces more evenly along the jawline.

Reduced Surgery and Recovery Time

This approach offers reduced surgery and recovery time compared to other dental restoration systems and ensures a more stable tooth replacement option using fewer implants. Critics argue that All on 4’s limited use of screws compromises its durability, since the tilted screws access only a restricted amount of bone at the back of your jaw. However, most clinicians who offer this technique utilise cone beam CT scans to ensure that the angulation is optimal for long-term success.


One of the main advantages of All on 4 implants is that they replace all teeth with just four dental implants, two in the front and two tilted at the back. This means that people with weak or thin jawbones, who previously weren’t eligible for traditional implants, can now benefit from this procedure.


Getting All on 4 implants doesn’t require invasive bone grafting procedures, reducing recovery time significantly. Patients can enjoy quicker results and faster healing times which allows them to return to their normal activities within a day or two. The permanence of the implant also eliminates issues associated with removing or adjusting dentures.


Research also shows that patients prefer All on 4 implants over traditional methods due to their convenience and effectiveness. A study published in The International Journal of Oral & Maxillofacial Implants found that patients fitted with All-on-4 implants experienced improved neuromuscular control compared to those fitted with traditional dentures.


All-on-4 implants are more functionally durable than traditional dental implants and easier to maintain than removable dentures. With proper care, dental implants can last a lifetime without any additional treatments.  However, it is important to regularly visit your dentist and practice good oral hygiene habits to help ensure the success of your dental implant for as long as possible.


Some patients ask what the difference is between All-on-4 implants and dentures. Many believe traditional dentures offer greater flexibility since they can be easily removed and cleaned. Yet, there’s a downside—dentures often slip out of place, which can cause embarrassment and discomfort for wearers. With fewer supporting implants, All-on-4 has more flexibility to design and fit teeth that look and feel natural.


All on 4 is often suitable for more complex cases and is therefore a possible treatment option for anyone with damaged or missing teeth. Whether you’ve lost teeth due to injury, have gum disease, or if you have multiple missing teeth, All on 4 might be able to help. However, as with all treatments, your suitability can only be confirmed following a comprehensive examination. To determine whether you are a suitable candidate for All on 4, your implant dentist will review your medical history, take x-rays of your jaw and remaining teeth and consider any lifestyle choices that might impact the success of treatment.

In the meantime, we have created an implant suitability quiz that identifies whether you are a candidate for dental implant surgery. Take the quiz and we’ll send your result immediately.


When choosing an all-on-4 dentist in Sydney, it is crucial to ensure that you get the best results for your investment. There are lots of Sydney dentists who offer implant treatments, which can make choosing between them incredibly difficult. However, it’s vital to understand what you’re being offered and not to make a choice based on cost alone. To ensure you get the best quality treatment, service, and results, you must understand what makes a dentist an All-on-4 implant expert. take the following three factors into consideration.


While it’s relatively easy for dentists to take short courses to qualify them to place All on 4 implants, that doesn’t automatically mean they are vastly trained. When searching for an implant dentist, it’s crucial to identify a clinician who has invested in their education in implantology, has taken comprehensive postgraduate courses, and has focused their career on dental implants. This ensures your dentist will have the clinical, theoretical, and practical education required to provide the best possible treatment. This includes dental implant treatment planning, which is essential as it reduces the risk of complications and ensures the best possible outcome for the treatment.


If the All on 4 implant treatment was just another dental service amongst many, there is no way to know how much experience a dentist actually has. However, All on 4 is an advanced procedure and not all dentists can offer it. What you need to find out is whether your dentist regularly performs implant surgery, has a broad range of clinical experience, and has become accustomed to many different types of implant cases. When you find an experienced implant dentist, you can be confident that, regardless of the complexity of your case, you’re in safe hands.


It’s not just the dentist who can affect the outcome of your treatment; the materials used are equally important. You should ask any potential dentist about the quality of the implants and where they’re manufactured. Your implants should comply with Australian safety regulations and be made from high-quality materials. By verifying the standard of implant materials at the beginning, you might avoid complications caused by low-cost and inferior materials.




Acrylic-based prostheses may provide satisfactory performance for some patients, especially those looking for a low-cost solution as they cost less than porcelain implants. However, acrylic-based prostheses have additional issues like vulnerability to staining, crack formation and degradation over time.


Porcelain prostheses are considered stronger and more durable than acrylic-based prostheses. They feature high resistance to stains, which is great if you like coffee or red wine as they’ll resist discolouration even after long-term usage.

Ceramic Zirconium

Ceramic zirconium prostheses offer exceptional durability and strength. It is at least three times stronger than porcelain. In contrast to porcelain, zirconia is also able to withstand wear and tear without chipping. Not only is zirconium made from a material that is both strong and durable, they look and feel natural, and also have a much higher success rate than traditional implants. Furthermore, zirconia has outstanding biocompatibility. The high biocompatibility of zirconia does not cause allergic reactions in patients who are allergic to the alloys in porcelain restorations.

All on 4 is a fantastic solution that benefits many patients regardless of age, gender or budget. Although it is essential to work with an experienced implant dentist, you can be assured that your smile’s transformation will be effective and natural-looking. Remember also that the decision comes down to personal factors such as budget, medical history and risk for allergies.

It’s worth noting that selecting the best implant material for you isn’t always purely based on your preferences alone. Your dentist should consider factors like underlying medical conditions, risk of allergies, functionality, implant longevity, and wear characteristics when recommending which implant material would be the most suitable. Ultimately, whether you choose acrylic vs porcelain vs zirconia depends entirely on what best suits your clinical requirements and aligns well with your lifestyle needs.

Before & After images


If you have been looking into All on 4 implant dentistry and at the dental clinics that can undertake the process, you should be aware of the variation in cost. Implant treatments can set you back anywhere from $5,500 to $55,000, contingent upon the size of the treatment. Making a considerable financial commitment towards a dental implant procedure isn’t what most people have planned for. Indeed, All-on-4 may be included in your health insurance package. However, coverage heavily hinges on the type of policy you have and the insurance provider. For a guide to getting health insurance coverage for dental implants, click here.

Ultimately, with so many dental practitioners appearing to have the credentials to provide the All-on-4 treatment, it can get confusing. The following three variables can affect both the cost of your All-on-4 procedure as well as the overall result:

The level of education of the dentist: Reduces the risks and provides a superior outcome.
The right materials: Use only the best quality materials to maximise the durability of your implants.
The experience of the dentist: an implant dentist who has a broad range of use-case experiences, is more likely to provide you with the best treatment.

When evaluating the cost of All on 4, while you don’t want to pay more than you should, it’s important that your treatment is carried out by a highly skilled and experienced dentist using only the highest-quality materials. After all, the right investment in an implant dentist will help to avoid any costly or even painful complications later down the track.


We understand that the All on 4 treatment does come with a significant cost, which is why we do everything we can to help our patients to afford the investment in their smiles. We offer several interestfree payment plans so that you’re able to have the All on 4 procedure straight away and then break the cost into manageable payments.


We can help you use your superannuation against the cost of dental implant treatment and work in collaboration with Supercare to make the application process as simple as possible.


The All on 4 dental implant procedure is performed in three stages – planning, surgery, and restoration.

Stage 1 – The Planning; Dr Shehata will take impressions of your teeth and jaw to create a 3D model of your mouth. This model will be used to plan the placement of the implants.

Stage 2 – The surgery; four dental implants will be placed into your jawbone. Two implants are inserted in the front part of your jaw, while the other two are tilted at an angle at the back of your jawbone. This procedure usually requires only local anesthesia or conscious sedation, making it virtually painless. Unlike traditional implants that require lengthy preparation and additional surgery for bone grafting, All on 4 treatment allows for immediate loading onto the implants.

Stage 3 – Post surgery; a provisional set of teeth is placed over the implants before they fully integrate with the surrounding bone tissue. The provisional teeth function like normal teeth but should be treated with care while the integration takes place. Once the integration has taken place, which could take around six months, permanent replacement teeth that look and feel like natural teeth will replace the provisional teeth.
