In this case, the term "rejection" is not entirely true! Rejection can occur, for example, in serious operations such as implantation of donor organs. Our body does not produce antibodies to titanium that promote rejection. Practice shows that with implantation the survival rate is 97-99%.
And yet, if the implant does not take root, this often occurs for 3 reasons:
- non-compliance by the patient with oral hygiene and doctor's recommendations
- features of the patient’s body that cannot be influenced
- lack of professionalism of the doctor (violation of the installation protocol)
Let us see which of the doctor’s recommendations, patients violate most often:
1. Inadequate oral hygiene, the patient does not clean the implant and the area around it poorly
2. The patient does not use an irrigator
3. The patient does not visit the dentist 2 times a year for a routine examination
4. The patient does not take pharmaceuticals and leads an extreme lifestyle (temperature changes, active sports, etc.)
Every patients body is different and may have:
- acquired diseases after implant placement, affecting metabolic processes (for example, diabetes mellitus) and hiding these diseases from the doctor at the very beginning of the procedure
The professionalism of the doctor may also be the cause, in which case, a technical error was possibly made when installing the implant. This happens, for example, if the doctor uses a new implant system when switching to which an installation error is made
Dentists and surgeons note the following terms for the loss of an implant:
- short term from 2 weeks to 4 months
- long-term from 4 months. During this time, a chewing load influences the fusion of the implant with the bone.
If, after 2 weeks after the removal of the sutures, inflammatory signs have occurred around the implant, aching pain, fistulous passage with separable fluid occurs, this indicates that the process of rejection occurs. But this process does not mean 100% loss of the implant, in this case the implant is opened, a rehabilitation procedure is carried out, that is, an antiseptic treatment of the wound, according to indications, oral preparations and physiotherapeutic procedures can be prescribed. In some cases, in the presence of systemic diseases, this process cannot be stopped. The doctor decides to remove the implant. Then, after 1-1.5 months after healing, a repeated implant placement procedure is performed.
The reason for the loss of the implant in the long term is primarily an improperly manufactured orthopedic design. The same technical error that we wrote about earlier. And some violations on the part of patients. That is, in this situation, rejection occurs both through the fault of the doctor, and through the fault of the patient. Especially if the patient does not follow proper oral hygiene and abuse smoking.
Another important question: how long do implants take root? Within 2-6 months, bone tissue is regenerated (restored) around the implant and its fixation is reliable. After that, the implant is ready for perception of chewing pressure in full.
To summarize, we can say the following: for the correct and quick survival of the implant, we recommend that you clearly follow all the recommendations of the doctor and do not forget to visit the dentist for preventive purposes once every 6 months.
