Immediate fixed teeth (All-on-4®)

The “immediate fixed teeth” technique, or All-on-4, gives the patient a perfect smile in just one day, thanks to the placement of All-on-4® implants and a fully fixed bridge. With our partner, this smile is digitally designed and adapted to each patient. In a few hours, it is possible to regain dental aesthetics, chewing ability and a smile.

The “immediate fixed teeth” technique is used in situations such as:

Patients with removable prostheses (dentures);
Patients with generalized tooth mobility;
Patients with irrecoverable teeth from an aesthetic and functional point of view;
Partially or totally edentulous patient.
We have a medical team with extensive experience in the
field of implantology, using the latest digital technologies that facilitate the placement of dental implants, with a minimally invasive surgery and, therefore, a painless postoperative period. Given the high quality of the materials used and the great experience of the medical team, the risks associated with the surgery of immediate fixed teeth (All-on-4®) are practically non-existent.

Having only 4 implants fixed in each jawbone makes this method a minimally invasive option, providing benefits such as:

  • A shorter treatment time;
  • Greater comfort;
  • Faster recovery and healing;
  • A decrease in the risk of complications;
  • The procedure can be performed even in people with severe bone atrophy and no bone graft
  • The patient receives a new fixed dentition the same day of the intervention
  • The actual success rate is 98%.

In addition, as it makes it easy to regain self-esteem and masticatory efficiency, the All-on-4 method is considered one of the main oral rehabilitation treatments.

Bone resorption due to teeth loss

Benefits of immediate fixed teeth

This method :
- Preserves bone structure - After tooth loss, there is a process of bone resorption. The dental implant is the only dental treatment capable of replacing the stimulation of the bone with the natural tooth, thus avoiding the loss of bone mass and the consequent alteration of the facial anatomy.
- Improves Aesthetics - Patients appear more beautiful, groomed and rejuvenated. Several studies indicate that people with missing or ugly teeth are perceived by others as older, less attractive and less groomed.
- Improves diction and communication - Missing teeth and certain tooth replacement options, such as dentures, can affect your ability to pronounce certain words correctly. Dental implants work like natural teeth and thus allow the patient to speak easily and naturally.
- Chewing Recovery - As dental implants are anchored in the bone, replacing the tooth root, they allow the patient to apply the same force as if it were a natural tooth. Other rehabilitation options, such as removable prostheses, because they rest on the gum instead of the bone, do not restore chewing ability as effectively.
- Improved well-being and self-esteem - Several studies show that a beautiful smile is not only linked to self-esteem, but also to well-being and happiness in people's lives. People with beautiful smiles are more confident, less anxious and enjoy life better. When you have a beautiful smile, you can talk and laugh without fear and enjoy the happiness and well-being that comes with it.

Immediate Fixed Teeth Assessment Process

01. Pre-surgical planning
During this first phase of the treatment, we assess your general state of health as well as your expectations regarding the treatment. Complementary diagnostic examinations such as orthopantomography and CBCT-3D will be necessary. The patient will have the opportunity to see the final smile idealized by our specialists, thus anticipating the final result of the treatment.
02. Surgery and placement of immediate fixed teeth
The surgical protocol adopted by our partners is performed under local anesthesia and makes it possible to treat most cases without resorting to additional complex surgery, such as bone grafting, which allows a quick and comfortable post-operative period and a rate of recovery. high patient acceptance. After surgery, the long-awaited process of fitting the previously planned fixed teeth and placing them in the mouth begins.
03. Permanent fixed teeth
After the bone healing period (4 to 6 months), the molds will be made to make the permanent teeth and place them.
04. Surveillance continue
At Thecaretrip, we offer patients a comprehensive service that continues after implant placement to ensure success.

Frequently asked questions about dental implants

01. What is All-on-4®?
All-on-4® is a revolutionary treatment that allows you to set fixed teeth in just a few hours by placing 4 implants and a fixed prosthesis, without resorting to grafts. Compared to traditional techniques that involve the placement of 6 or more implants, this technique has excellent postoperative recovery without pain and allows the fixed dentition to be placed immediately after the end of the surgery, without having to wait several months with uncomfortable removable prostheses.
02. Who is it for?
Immediate fixed teeth or All-on-4® are the best solution when the remaining teeth in the patient's jaw are so deteriorated that it is not possible to treat them. They are a fixed and durable solution. It is used in situations such as: – Patients with removable prostheses (dentures); – Patients with generalized tooth mobility; – Patients with irrecoverable teeth from an aesthetic and functional point of view; – Patient partially or totally edentulous.
03. Contraindications
Although they are an excellent solution, implants, as well as other surgical procedures, have their contraindications. - Children and young people who have not yet completed their bone growth cycle. Patients are able to place dental implants after the end of bone growth, around 18/20 years of age. - Patients using bisphosphonate class drugs. Patients taking bisphosphonates should check with their doctor about the possibility of stopping treatment. This type of medicine can affect bone turnover and is used to treat certain cases of osteoporosis, Paget's disease and malignant neoplasms.
04. Is it safe to place All-on-4® fixed teeth?
The All-on-4® technique is highly predictable with very high success rates (around 98%) and can be used in all types of patients (even smokers). Implants can last for decades or even a lifetime depending on hygiene habits, cleaning care, periodic check-ups and the absence of systemic diseases such as diabetes or oncological problems.
05. Is it painful to put on All-on-4® fixed teeth?
All-on-4® surgery is performed under local anesthesia. It is a simple operation and it is not painful. After surgery, there may be edema (swelling) and discomfort for 2-10 days, which will be alleviated by the medications provided. Introduce solid foods gradually, so as not to injure the gums. After a few days, you will return to your normal life.
06. What is the difference between all-on-4® and implants?
Implants are used to replace the root of the tooth and to support either a crown (the visible part of the tooth), or bridges that replace several teeth, or even complete dental prostheses, with aesthetic and functional characteristics close to natural dentition. . In case you need to rehabilitate the entire upper jaw using implants, the best solution is All-on-4®. With this technique, all you need to do is insert four strategically placed implants to secure your new denture. The advantage of this treatment is that it allows the rehabilitation of the entire jaw even with very little bone and, therefore, in most cases without resorting to bone grafts, which means that it is treatment suitable for all ages. In a single surgery consultation, you find your smile, the treatment time is much shorter and the postoperative period is lighter.
07. Implants or fixed prosthesis, which is the best solution?
The best solution for each patient must be analyzed with the dentist specializing in oral surgery and rehabilitation, during a face-to-face consultation and with the help of examinations to see the general condition of the patient's teeth, as well as as the quantity and quality of the patient's bone structure. . As a general rule, it is always good to opt for the most conservative option: keep your teeth healthy and replace lost teeth or teeth that are no longer aesthetically and functionally recoverable with implants. Immediate or all-on-4 fixed teeth are the best solution when the remaining teeth in the patient's jaw have deteriorated so much that it is not possible to treat them. Of course, each case is different and therefore it is important that during the diagnostic consultation you talk openly with your dentist about your expectations regarding the treatment and what bothers you about your teeth.

    Dental treatment in Portugal is cheaper because general operating costs, which include materials, laboratory costs and dentist fees, are lower in Portugal than in the UK. The same materials are sold by the brands themselves at lower prices in Portugal. Dentists do not charge as high fees as in other countries, so even our best dentists have a lower cost than dentists in other countries. We pay our dentists’ fees based on local prices (and based on their experience and quality), resulting in significant savings for our patients. Patients also often have to deal with very high laboratory costs. With Thecaretrip, a large part of the laboratory procedures are carried out in the dental clinic itself, which translates into lower prices for the patient, but with high quality, since the management of the process is carried out in-house, according to our high quality standards and by professionals we have selected. Some procedures must be carried out in rigorously selected external laboratories. Lower cost is often associated with lower quality. Wrongly. The dentists who work with us have been selected for their high level of specialization, the rigor and perfectionism with which they carry out their work and the attention paid to the patient. All the materials we use are certified and we only work with the best brands on the market.

    Dental implants are placed under local anesthesia, which minimizes the risks associated with a surgical procedure which is in itself painless. After surgery, there may be some swelling and discomfort, which will be resolved with prescribed medication. Ideally, after the procedure, the patient should rest for at least a day. This delay is important because rest slows circulation, which reduces the risk of pain. The next day, the patient can resume his professional activities in moderation. Compliance with post-operative care is essential for a good recovery, among which we highlight the following points:

    • Cold and soft foods: yoghurt, ice cream, gelatin, cold soups, pureed vegetables, meat and fish, fruit smoothies;
    • No physical exercise;
    • Avoid exposure to the sun;
    • Sleep with the head slightly elevated;
    • Regular cleaning of the operated area;
    • Take prescribed medications as directed.
