Service Overview

All-on-4 tooth replacement provides the convenience of dental implants and the affordability of dentures for natural-looking results that remain in place while eating, talking, and smiling.

At LN Dental in Chester Hill, NSW, we offer this solution that provides more stability than traditional dentures and is suitable for patients who may already have bone loss associated with tooth loss.

What Is All-on-4?

All-on-4 refers to an entire arch of teeth retained to the jaw (upper or lower) with 4-6 dental implants. The number of dental implants required depends on individual biting pressure. Your dentist will discuss appropriate implant placement with you with the aim of giving you the best long-term results. Implants are intentionally tilted to gain more bone support with fewer dental implants.

Often chosen over an implant-retained denture or fixed implant bridge, All-on-4 alleviates many chief complaints from patients with ill-fitting or uncomfortable dentures. Because the entire arch of teeth is retained with stable dental implants, one’s dietary choices, confidence, and quality of life can improve over traditional dentures.
Instead of replacing teeth with individual dental implants, All-on-4 captures the security of dental implants with fewer surgical procedures.

How Is All-on-4 Created?

To determine if All-on-4 implant-retained dentures are a viable option for you, we invite you to arrange an appointment in our Chester Hill, NSW dental clinic to speak with one of our dentists. They will present all of your options and help you make a choice that suits your lifestyle and budget.

Once you decide you would like to pursue All-on-4 as a treatment option, you can expect the following:

  • A full oral evaluation
  • Diagnostic x-rays and imaging
  • Treatment coordination and design
  • 3-D CBCT images of bone and facial structure
  • Digital impressions
  • Digital smile design (smile preview)
  • Wax-up and try-in
  • Surgical guide creation for implant placement
  • Implant surgery (bone grafting or sinus lift, if necessary)
  • Immediate All-on-4 denture placement
  • Follow-up appointments, as recommended by your dentist
  • Final All-on-4 placement

With All-on-4, in most cases, we provide immediate teeth within a week and permanent teeth per the dentist’s recommendation. Dental implants are made of biocompatible materials, such as titanium, which are readily accepted by the body.

When it comes to the appearance of your new smile, our dentists want you to feel confident in the way your teeth look. They will discuss the shade, shape, and color of your All-on-4 teeth before your final prosthetic is created.

What Are the Advantages of All-on-4?


All-on-4 is gaining in popularity because of its versatility and affordability. In addition to remaining locked in by dental implants, your denture can last for many years with the proper care. Due to strategic dental implant placement and the locking mechanism, you can avoid sticky and cumbersome dental adhesives.

All-on-4 dentures are also low-profile, leaving the palate exposed. This means you can taste and enjoy your food thoroughly. Because they are secure, your food choices increase – you can enjoy meats and vegetables previously difficult to masticate with traditional dentures.

When Is All-on-4 the Best Option?

Our dentists in LN Dental Centre will always present all of your treatment options. They are your resource for questions and guidance. But, ultimately, the choice is yours when it comes to your oral health and smile.

In general, All-on-4 works best for patients who are frustrated with dentures that never seem to fit correctly and move or fall at inopportune times. Denture adhesives are never ideal, and the need for constant reapplication often leads patients to All-on-4 as an alternative. Patients who love enjoying good food with family and friends also prefer the improved ability to fully taste their favorite cuisine.

Whom Does All-on-4 Benefit?


Patients who want a stable smile and want to avoid full-mouth single dental implants and the necessary surgeries benefit most from All-on-4. If you want to learn more about full-mouth tooth replacement on your upper arch, your lower arch, or both, please reach out to our experienced team to arrange a booking with one of our All-on-4 dentists in Chester Hill, NSW.

Which is better between Acrylic vs Zirconia For All-on-4 Teeth?

We strive to design natural-looking dentistry at LN Dental Centre, and both acrylic and Zirconia provide stunning aesthetics. Acrylic materials are more forgiving when chewing, but are also subject to greater wear over time.

Zirconia is a harder and more durable material, but places more pressure on the implants, and therefore the bone, so is typically not recommended for immediate All-on-4 teeth. Zirconia All-on-4 may be a superior option for permanent All-on-4 teeth for those with a strong bite or bruxing (teeth grinding) habit.

Most All-on-4 prosthetics last between 15-18 years. However, it is not uncommon for some patients to need replacement within five years, depending on their unique needs.

Why Should You Get All-on-4 at LN Dental?

At LN Dental in Chester Hill, our dentists combine their years of experience with the latest dental technology for precise and accurate surgical procedures. With CBCT 3-D imaging, your implant dentist can locate the ideal place within the bone for implant placement and long-lasting results.

Because dental implants are permanent and poorly placed All-on-4 dental implants are difficult to fix, choosing a dental clinic with experience in All-on-4 placement is essential. Our dentists are committed to precise surgical treatment and ideal results. Their eye for detail and artistry ensures that restorations and prosthetics, like dentures, match your appearance for a seamless smile.

Our dentists are fully aware that going to the dentist can make some people feel a bit anxious. Our compassionate and gentle dentists aim for you to feel completely confident and comfortable while in our care. If you need some additional help relaxing, we offer sedation dentistry options for a stress-free experience.
