All-On-4 Procedure

Stage 1: Consultation

  • Detailed Exploration of Concerns

When you attend your consultation at Nuffield Dental, our team of dentists will discuss all your concerns regarding the procedure and ultimately, if you are suitable for an All-On-4 surgery. 


  • Full Dental Assessment

Our dentist will thoroughly examine your general health, as well as the condition of your teeth and gums. This may include having to take some X-rays and CBCT scans (Cone-beam computed tomography). The CBCT Scan is a medical imaging technique to consisting of X-ray computed tomography. A divergent pyramidal- or cone-shaped source of ionizing radiation is directed through the middle of the area of interest onto an area x-ray detector on the opposite side, as sometimes an X-ray may not be able to give a specific area that requires scanning a specific image. These steps are taken to assess your suitability for the All-On-4 dental implants procedure or other treatment options.


  • Individualised Treatment Plan

Our dentists will hereafter thoroughly explain your condition, the benefits and risks of each of the possible options, and tailor a final treatment plan after consulting with you.

Stage 2: All-On-4 Procedure

  • Anaesthesia

Before commencing, the relevant areas will be completely numbed with local anaesthetic so that you will not feel any pain at all during the whole procedure, solely slight pressure or vibrations.

  • All-On-4 Dental Implant Procedure

Our dentist will first carry out any necessary extractions of the relevant teeth. Thereafter, he or she will precisely place suitably-sized All-On-4 implant fixtures into your jaw bone.


  • Interim All-On-4 Dental Implant Bridge Prostheses

Our in-house laboratory will then proceed to custom-make your interim All-On-4  dental implant bridge prostheses. These will be fitted to your implant fixtures in the same sitting, successfully restoring your smile, form, and function on the same day.

Stage 3: Post-operative

Your body requires a few days to accept the implant. You will then be required to come down for a second appointment for the dentist to access the healing process.

  • A bridge will be inserted into the patient's mouth.
  • However should all of the above treatment plan be unsuitable for you due to jawbone loss(as this treatment differs depending on the needs of the individual) sometimes you may require a Zygomatic Implant. This implant is suitable for patients who have severe bone loss or lack of bone volume in the upper jaw but still want dental implants. 

Benefits Of All-On-4 Dental Implants

Benefits of All-On-4 Implants

  • All-On-4 implants look and feel like your natural teeth.  They provide an efficient and effective way to replace a full-arch of teeth overnight. 
  • Permanent Solution. Unlike dentures that could risk falling out mid-way through a day, All-On-4 poses as a long-term solution.
  • Convenience. Instead of having to remove dentures, All-On-4 works like your own natural set of teeth and requires no sticky dental adhesive. 

  • Durable and Long-Lasting. Once your All-On-4 implants are successfully fused into your jaw bone, these implants are known to last a lifetime with proper maintenance and care. 
  • Completion in one surgery. The entire All-On-4 surgery is done in one single surgery, which means less discomfort that you would have to experience.

    As with all surgeries, this is highly dependent on the health related risks that come along with an individual.

  • Implant failure. This happens when your body rejects the implant, which also means that your jaw bone is unable to fuse with the All-On-4 implant.


Risk of infection. Any type of surgery could run a risk of infection, however, the risks for infection can be cut down with proper aftercare. The type of infection to look out for in this specific case would be peri-implantitis, which is a type of infection associated with implants. Symptoms associates with Peri-implantitis is as follows;
  1. Bleeding or pus.
  2. A fever.
  3. Throbbing pain.

  • How long can my All-On-4 Dental Implant last me?
    All-On-4 dental implants use the same technology as traditional implants such that when the All-On-4 dental implants fuse with the patient’s bone during the healing process, they will have a lifespan that is similar to traditional implants. Vast majority of dentists agree that patients can expect All-On-4 dental implants to last at least 20 to 25 years, with the potential to last the duration of the patient’s life.

  • How long does the All-On-4 procedure take?
    The surgery itself takes about 2 - 2.5 hours per jaw(or per arch).
  • How do All-On-4 dental implant compare to traditional implants?
    The All-On-4 dental implant technique uses solely four implants per arch, whereas traditional implants use anywhere from six to eight implants or in each arch. The implants of the All-On-4 procedure are also placed at an angle, which allows for increased contact by using the natural support of your bone. In addition, the All-On-4 procedure requires no bone grafting for many patients, which is common in traditional implant procedures. 

  • Can I just do an All-On-4 Dental Implant for one arch? What if I someday need All-On-4 Dental Implant on both arches?
    All-On-4 dental implants can be placed on just the upper or lower arch. An implant provider will evaluate your circumstance and if they feel you might eventually need replacement teeth on both the upper and lower arches, they may suggest performing the procedure on both arches at the same time. This provides enhanced results while also saving time and money. Your doctor will work with you to determine what best meets your health needs and financial situation.
  • What is the recovery time for my All-On-4 Dental Implant?
    The downtime for the All-On-4 Dental implant process differs with each individual. The sedation should wear off in approximately 4-5 hours, after which the healing period would be about 3-5 weeks. People take about 6-8 months for the implants to be integrated with the jawbone.
