Implantation with complete absence of teeth
The absence of all teeth is a serious dental problem that affects not only the aesthetics of a smile but also the health of the entire body. Diction is impaired, the face shape changes, eating becomes difficult, and later, digestive problems and even psychological discomfort arise. Modern dentistry offers a reliable solution – dental implantation, which allows for the restoration of chewing function and the return of self-confidence even with complete edentulism (total tooth loss).
How are implants placed when there are no teeth?
Implantation for complete edentulism is the process of embedding artificial roots (implants) into the jawbone, onto which a fixed prosthesis is subsequently attached. At first glance, it might seem that in such cases, an implant would need to be installed in place of every lost tooth, but in practice, this is not the case. Modern technologies allow for the restoration of the entire dentition using a minimum number of implants.
The first stage is diagnosis and planning. The doctor performs computed tomography and jaw scanning, assesses the state of the bone tissue and mucous membrane, and identifies anatomical features. Based on the data obtained, planning for the future restoration and surgical intervention is carried out; if necessary, surgical templates and temporary prostheses are modeled to be installed immediately after the operation.
If there is insufficient bone tissue, bone grafting or sinus lifting may be required—procedures aimed at restoring bone volume for reliable implant fixation. Alternatively, depending on indications, specific implantation techniques may be chosen, such as pterygoid implantation, trans-sinusal, trans-nasal, incisive canal implantation, or zygomatic implantation. After preparation, the surgical stage is performed – implant placement and soft tissue plastic surgery. Special abutments are placed on the implants, followed by temporary crowns or prostheses. After full integration of the implants (the osseointegration process takes 3 to 6 months), temporary prostheses are replaced with permanent ones.
What is comprehensive dental implantation?
Comprehensive implantation is an approach where the patient receives a full restoration of the dentition within a single treatment program. It includes not only the placement of implants but also all related procedures: diagnostics, treatment of oral diseases, bone tissue preparation, temporary prosthetics, and the fabrication of the permanent structure.
The main goal of comprehensive implantation is to restore function and aesthetics with a minimum number of surgical interventions. This approach is especially important for complete edentulism, where the anatomy of both jaws, the bite, and the load on the implants must be taken into account.
Comprehensive implantation can be carried out according to different protocols, but the most relevant, predictable, and reliable one is where a temporary prosthesis is fixed to the patient as soon as possible after surgery (within 7-10 days). This avoids the "toothless" period and quickly returns comfort to daily life.
Furthermore, digital technologies are used in comprehensive implantation: 3D scanning, computer modeling, and navigational surgery, ensuring precision in implant positioning and a predictable result.
What is the "All-on-4" and "All-on-6" implantation process?
The All-on-4 ("everything on four") and All-on-6 ("everything on six") methods are innovative solutions for patients who have lost all their teeth or have hopeless teeth scheduled for extraction. Like any methodology, this method has its indications and limitations, which must be discussed with a doctor. Their essence is that the entire dental arch is fixed onto four or six implants, which are installed at a certain angle for even load distribution.
In All-on-4 technology, four implants are used: two in the front part of the jaw are placed vertically, and two rear ones are placed at an angle of 17-30°, allowing the bypass of areas with insufficient bone volume. Just a few days after the surgery, a temporary prosthesis is attached to the implants, and after full integration, a permanent one is fitted.
The All-on-6 method is similar but involves the installation of six implants, providing additional stability and a more even distribution of the chewing load. This option is more often chosen when there is good bone volume or in cases where maximum durability of the structure is required.
Main advantages of "All-on-4/6" systems:
- Minimum number of implants for full restoration of the dentition;
- Short treatment timeframes (possibility of installing a temporary prosthesis immediately after surgery);
- High aesthetics and a natural-looking smile;
- Reliable fixation, no chafing or discomfort characteristic of removable dentures.
Thus, implantation using All-on-4 and All-on-6 protocols has become a revolution in dentistry, allowing thousands of patients to restore their teeth even with bone atrophy and the impossibility of classical prosthetics. Modern implantation technologies open up the possibility of returning a full smile to people of any age. With proper planning and adherence to the doctor's recommendations, implants serve for decades, providing comfort, confidence, and a quality of life comparable to natural teeth.
