With age, tooth loss may occur gradually or suddenly due to several reasons such as gum disease, tooth decay, or chronic illnesses like diabetes. Losing teeth can make eating less enjoyable, cause embarrassment when speaking, and even make a person look older.
Unfortunately, tooth loss leads to the resorption of the surrounding bone and jawbone, making tooth replacement much more complex and limiting the available options. Therefore, it’s recommended to visit your dentist shortly after losing teeth so that they can provide the most suitable treatment plan.
The All-on-4 technique is a real breakthrough in dental implantology, allowing patients to receive a full, fixed arch of teeth in just one day. This method was developed to enable the placement of permanent, implant-supported restorations using only four dental implants. It provides an efficient and simpler alternative to traditional dental implant procedures, which often required multiple implants or complex bone grafting surgeries.
When thinking about tooth replacement, many questions arise — How can missing teeth be replaced? What are the best solutions? Are they suitable for everyone? What are the pros and cons? In this article, Wonders Dentistry answers all these questions clearly and simply.
Are all dental restorations the same?
Dental restorations are a broad category of prosthetic solutions divided into two main types: fixed restorations and removable restorations.
The first group, fixed restorations, replace missing natural teeth and cannot be removed by the patient after placement — hence the name “fixed.” They are long-term solutions that include dental bridges, dental implants, and implant-supported dentures.
Removable restorations, on the other hand, can be taken out and reinserted. They either replace some missing teeth — known as partial dentures — or all missing teeth, known as complete dentures.
What are All-on-4 dental implants and what are their steps?
All-on-4 restorations are a type of fixed dental prosthesis, sometimes referred to as hybrid restorations, as they combine the benefits of both fixed and removable dentures. They resemble complete removable dentures, but the difference is that they are secured to the jawbone with four strategically placed dental implants, providing excellent stability.
The number of implants used in this technique is four implants per jaw, each positioned at specific angles. The dental surgeon plans the procedure with great precision to ensure optimal results.
Are All-on-4 dental implants right for you?
All-on-4 dental implants are suitable for most patients, especially those who:
- Suffer from bone resorption, such as diabetic patients or those who have lost their teeth long ago and consequently lost significant jawbone volume.
- Have maxillary sinus enlargement in the upper jaw, where a complex sinus lift surgery might otherwise be required. Compared to that, the All-on-4 procedure is simpler, faster, and less invasive.
- Experience instability with complete removable dentures, particularly when bone resorption is severe — in such cases, All-on-4 offers a secure and comfortable solution.
- Would otherwise require multiple implants to replace several teeth, which increases cost.
- Wish to restore their smile with a natural and aesthetic appearance.
Steps of the All-on-4 Dental Implant Procedure
- Comprehensive examination and 3D imaging: Using CBCT scans to evaluate bone density and determine implant placement angles.
- Digital treatment planning: Specialized software is used to optimize implant positioning and avoid vital anatomical structures.
- Local anesthesia: The area is precisely numbed to ensure patient comfort without the need for general anesthesia in most cases.
- Placement of the four implants at strategic angles: Each implant is secured at a specific tilt to maximize bone contact and provide solid support for the bridge.
- Immediate temporary teeth placement: Temporary prosthetic teeth are fitted on the same day for immediate function and aesthetics.
- Follow-up after 24 hours: To evaluate healing and initial bone integration.
- Final restoration after 3–6 months: The temporary bridge is replaced with a permanent, durable one once osseointegration is complete.
- Oral care and hygiene instructions: The patient receives detailed guidance on maintaining long-term implant health.
Advantages of the All-on-4 Dental Implant Technique
Immediate results (fixed teeth within 24 hours): In most cases, temporary All-on-4 teeth are placed immediately after implant surgery, allowing the patient to leave Wonders Dentistry the same day with a complete smile and restored chewing ability.
Avoids bone grafting in most cases: Thanks to the strategic angulation of implants, the need for additional bone grafting surgeries is minimized, making it ideal for patients with reduced bone volume.
Lower cost compared to individual implants: Using only four implants per jaw significantly reduces the overall cost compared to replacing each missing tooth individually.
High success rate (over 98%): Studies show that All-on-4 dental implants have a success rate exceeding 98% when proper hygiene and follow-up are maintained.
Advanced implant design: The technique relies on digital 3D planning to determine precise implant positions, enhancing stability and reducing bone stress.
Durable and biocompatible materials: Permanent prostheses are often made of porcelain or zirconia, materials that are highly durable and biocompatible, minimizing allergic reactions and maintaining a natural tooth-like appearance.
Fixed and non-removable: Being fixed restorations, they eliminate the embarrassment and inconvenience of dentures slipping or falling out.
Indistinguishable from natural teeth: Thanks to advancements in restorative materials, All-on-4 teeth look and feel natural, providing a youthful, radiant smile.
Minimally invasive surgery: Although it involves implant placement, the procedure is much simpler and less costly than traditional full-mouth implant surgeries.
Disadvantages of All-on-4 Dental Implants
It is a replacement for missing parts of the body designed to mimic what has been lost; however, it will never be 100% identical to the natural teeth, as it is man-made. Continuous research is being conducted to improve these restorations and bridge the gap between artificial and natural structures.
- Since it is an artificial restoration, it can become a source for fungal accumulation, and its color may change over time — which is why proper care and maintenance are essential. Don’t forget to visit your dentist periodically, according to the pre-scheduled appointments, to ensure the longest possible lifespan for your All-on-4 restorations.
- The prosthesis may face some issues — either technical problems during the implant placement, while fixing the restoration, or during regular use, such as fractures or difficulties in cleaning.
- Another potential issue is that the planning process involves multiple stages; if these steps are not carried out systematically and accurately, the results may be imprecise. Therefore, this treatment must always be performed by a skilled and specialized implant dentist experienced in this type of restoration.
- Although dental implant surgery is considered a simple procedure, it is still a surgical process — you might experience some mild pain or swelling afterward, which usually subsides quickly.
- Fixing issues that may arise later, such as fractures, implant failure, or instability, can sometimes be complex.
- Additionally, placing implants at specific angles requires accurate planning using a CT scan of the jaw, which can be costly and must be of high quality since the entire treatment plan depends on it.
Difference Between All-on-4 and Traditional Dental Implants
In traditional dental implant procedures, each missing tooth is replaced with an individual implant, often requiring bone grafting or six or more implants per arch. In contrast, the All-on-4 technique uses only four strategically placed implants, usually avoiding bone grafting altogether, simplifying the process and reducing treatment time.
Aftercare for All-on-4 Dental Implants
Maintain strict oral hygiene using a soft-bristled toothbrush designed for implants. Use antibacterial mouthwash daily. Avoid hard foods during the first month. Completely stop smoking, as it negatively affects implant health. Schedule regular checkups every 6 months at Wonders Dentistry to adjust bite alignment and monitor implant and tissue health.
Conclusion
The All-on-4 technique provides a revolutionary, fast, and effective solution for patients who have lost most or all of their teeth. With only two steps — implant placement and temporary bridge fitting — patients can achieve an instant, natural-looking smile while saving time and cost compared to traditional methods.
