what are all on four dental implants

The all-on-4 procedure provides a simple and rapid approach to give patients what they want. If you wear a denture or have failing teeth then all-on-four could greatly improve your quality of life and restore your confidence. Advances in dental implant therapy now allows patients to benefit from fixed bridgework on the same day, often without the need for bone grafting. This is a very successful and viable alternative to dentures and conventional implants.

 

  • You will have a beautiful smile, and a full set of functional teeth supported by a state of the art implant system. Completely replace your old denture in just one day!
  • Cheaper than conventional implants: All on four can be offered for a fixed cost, which includes all consultations, appointments, implants and cosmetic dental work.
  • Referring dentists can also participate in their patients’ treatment by inserting the final support structure.

Procedure – Detailed explanation for teeth in a day
All on 4

Procedure 1 – Consultation at the beginning of the day

Consultation to discuss your requirements, and a full clinical examination. After this has been carried out we will present you with different options and also an estimate of the treatment costing. If you are already wearing a complete denture or dentures then appropriate appointments for the day will be made to prepare for your all on 4 solution.

Procedure 2 – X-Rays and CT Scan

Once this has been completed then we will take a CT scan at the practice which will give us an idea of the bone quality, quantity and also the proximity to vital structures such as nerves and sinuses. The I-CAT scanner is specially designed for dental use. It is an extremely safe machine with probably the lowest radiation dose of any machine available in the market. As a comparison to a hospital dental CT scan, it has approximately 10% of the radiation dose.

Procedure 3 – Diagnostic mock-up and treatment planning

All-on-4 can be planned and performed using NobelGuide treatment concept, ensuring accurate diagnostics, planning and implant placement. The NobelGuide software allows detailed diagnostics such are identification of available bone, virtual placement according to the anatomical situation and the prosthetic needs, and the ordering of the individualised surgical template. NobelGuide supports minimally invasive techniques, with the surgical template ensuring guided and therefore exact implant placement.

Procedure 4 – Surgical placement of dental implants & remove failing teeth (If required)

The surgical phase of the treatment is carried out by a specialist dentist called a periodontist who specialises in the treatment of periodontal conditions and placement of dental implants, a periodontist can be more commonly known as a dental implant surgeon in this case. The treatment can be carried out under intravenous sedation. This is a very relaxing and safe way to alleviate any dental anxiety. With this procedure a small amount of a sedative called midazolam is injected into the back of the hand and this works quite quickly and is very relaxing. Any failing teeth can be removed at this stage and all the implants are then inserted at the same time under local anaesthetic. Once they are firmly in place the prosthodontist takes over.

Procedure 5 – End of the day your non-removable replacement teeth are fixed

The next phase is to make you a bridgework and you will have full control the size, shape and colour match of the teeth. This will be done a specialist dentist called a prosthodontist. A Prosthodontist is dentist who has undergone 3 years of further postgraduate full time study at University. This is addition to the dental degree that all dentists have to do. The prosthodontist will help you to come to fully consented decision on the final bridgework. Here the dentist will check the bite and take impressions of the implants and these will be handed over for the dental technician to connect the implant bridge . Once the Dental technician has finished and polished the bridgework the prosthodontist will attach this to the dental implants. The bite will be checked and then the patient is discharged.

Procedure 6 – The final bridgework is made out of titanium framework

You will return for your next appointment around 4 months later. Radiographs of the implants are taken and if there are no issues the final definitive bridgework is fitted. Radiographs are taken to check the bone density around your implants. The final bridgework is made out of titanium framework which gives it great strength and durability. Again the procedure involves checking the bite along with the fitting of the new teeth. Any family members or friends are encouraged to come along and give any feedback on the final teeth.

The principle of All-on-four clinical solution

1) All on 4 is a much simplified concept for full arch rehabilitation that will provide predictable aesthetic, fixed, functional, non removable teeth in one day, without the need for bone grafting in most cases.

2) Denture teeth are inserted and fixed to gums in the same day to be worn as a transitional prosthesis. The patient will be able to function on this prosthesis immediately.

3) The all on 4 clinical solution has been developed to maximise the use of available bone and to allow for immediate function.

4) The all on 4 solution takes advantage of the benefits of tilting the posterior implants to provide secure and optimal prosthetic support for a prosthetic bridge, even with minimum bone volume.

5) The all on 4 process uses only four implants in edentulour jaws, making full use of dense bone at the front of the jaw, the implants are placed at exact angles.
