Dental implantation can be performed using different protocols. The choice of technique depends on the condition of the bone tissue, the time since tooth loss, the presence of inflammation, and the plan for subsequent prosthetic treatment.
According to the timing of implant placement
The following implantation options are distinguished:
- Immediate implantation (instant). The implant is placed immediately after tooth extraction — into the socket of the freshly removed root, provided there is sufficient bone volume and no active inflammation.
- Delayed implantation. The implant is placed some time after tooth extraction, once the tissues have healed and a stable bone foundation has formed.
This classification makes it possible to choose the optimal time for placing the artificial root, taking into account tissue condition and the clinical situation.
According to the need for bone augmentation
Depending on bone volume, implantation is divided into:
- Without bone grafting. Performed when the existing bone tissue is sufficient for stable implant fixation.
- With bone augmentation. Bone grafting or sinus lift is performed before or simultaneously with implantation if bone tissue volume is insufficient.
This planning stage is important to ensure reliable fixation and successful osseointegration.
According to the timing of crown placement
Depending on clinical conditions, the following approaches are used:
- Immediate loading. A temporary crown is fixed within the first days after artificial root placement if sufficient primary stability has been achieved.
- Delayed loading. The crown is placed after the osseointegration period, usually after several months.
The timing of loading is determined by the doctor based on implant stability and healing processes.
According to the number of surgical stages
Implantation is also divided into:
- One-stage implantation. The implant is placed together with a gingival former without complete soft tissue closure, allowing avoidance of a second surgical intervention.
- Two-stage implantation. First, the implant is placed and covered by soft tissue, and after osseointegration a separate stage is performed to place the gingival former and crown.
This approach allows selecting the safest and most appropriate treatment option for each individual patient.
Implantation in Cases of Significant Tooth Loss
In addition to replacing one or several teeth, dentistry also uses methods for full dental arch restoration. These approaches are intended for patients with pronounced edentulism or in cases where placing a large number of individual implants is technically difficult or impractical.
One such solution is the All-on-4 protocol, in which a fixed prosthesis is supported by four implants placed in strategically important areas of the jaw. This approach makes it possible to achieve stable fixation of the prosthetic structure even with a limited volume of bone tissue and to reduce the extent of surgical intervention.
Another option for full-arch implantation is the All-on-6 protocol, which involves fixing a non-removable prosthesis on six implants. This method is used in clinical situations where anatomical conditions allow for the placement of additional supports, ensuring more even load distribution and increased stability of the structure.
The choice of a specific full-arch restoration method is made after diagnostic evaluation and assessment of the clinical situation, taking into account the condition of the bone tissue, the bite, and the overall treatment plan.
