Dental Implant
Dental implant is a screw of titanium alloy that is placed in the toothless area inside the jawbone, and just as the root of a tooth inside the jawbone has a basic role for preserving and functioning of the crown, dental fixtures or implants also act as a solid foundation when placed inside the bone, which in the future will be placed on this base, dental veneer and dental crown Instead of missing teeth, it brings beauty and functionality.
Introduction to dental implant services
Although the majority of dentists believe that the priority of keeping one’s own tooth and preserving the crown and root is important, but when we encounter widespread crown decay or unsuitable conditions of the root of the tooth or gum and bone preservatives and do not see the conditions for crown reconstruction and tooth maintenance, inevitably the treatment plan is to remove the tooth and implant placement instead is given of the missing tooth.
The importance of dental implants among patients who lost their teeth has grown in recent decades, and when a tooth loses its maintenance capacity for multiple reasons and you have to remove it, you can use a dental implant unit instead of that decayed tooth.
Lifetime of dental implants
According to people’s awareness to replace missing teeth with implants, the durability and longevity of implants have always been of particular interest to patients.
In fact, the longevity of implants implanted in bone depends on several factors, the most important of which is the amount of bone and gum health in that area and proper integration within the bone.
Regardless of the fact that the type of fixtures biologically and the material structure of the implant itself is a very important factor in the process of implant graft to bone and adaptation in the jaw environment. The technique of the surgeon or the implantologist is also very important in how the implant is placed in place.
In fact, we don’t mention for dental implants lasting for many years, because implants are a graft that if the patient is working properly and the patient carefully observes the health principles, it will have a long-term shelf life like the person’s own tooth.
It is essential to note that the human tooth that is part of the creation of the Lord in the human body is destroyed and lost by negligence or lack of proper use and lack of hygiene by the individual, nothing is inherently like the human tooth, and you should know about implants, as the teeth are destroyed and destroyed by non-compliance with hygiene tips, the implant is also associated with Lack of hygiene and negligence may lead to failure and loss.
Dental Implant
Various brands and companies in the world are producing and distributing dental implants, and the difference between fixtures is related to the type of texture and material production of that company.
However، if you are looking for an implant with ideal conditions، the most important pillar is to see your oral surgeon or a peridontist. Contact the receptionist for advice.

Types of dental implants
Today, more than 300 types of dental implants are procured, distributed and used in the world from different companies and companies. Fixtures that are capable of accelerating the mechanism of osteointegration with high adaptation to bone and bone grafting and the formation of stronger and faster tissue in the area are more valuable for the surgeon.
In choosing the type of implant, those fixtures that make up the fissure surface are more biometric and more compatible with the environment and do not damage the lateral tissues, is more valuable.
Fixture body design, material, production methods, hardness and body tissue all contribute to the fixed and better grafting of this implant into the jaw bone
Of course, in principle, and academically, all implants should have this capability, and this factor is one of the important factors that cause a surgeon to offer you a specific brand and implant to be assured of both patient and surgeon in terms of quality.
How is the procedure of implant surgery?
In the first stage, the surgeon of the maxillofacial surgeon visits the patient and examines the conditions of the toothless area, the gum and bone conditions of that area and the condition of the patient’s jaw collagen.
The OPG and radiographs of the patient will be given a CT scan of the jaw bone if needed to check the bone condition, sinuses, bone erosion and bone loss, bone density in the area and the conditions of that area with the help of a CT scan in three dimensions. And as a result, have a more accurate measurement for implant placement.
In one-stage surgery, after the implant is placed inside the bone, then a screw called healing, which actually does the gingival forming, is placed on the implant. This screw is placed outside the bone and on the gum and is therefore visible.
After about two months of implantation and implantation is implanted into bone, this healing screw is removed from the implant and replaced with a piece called "abutment.
Abutments play a permanent role in the connection between the internal bone fixture and the veneer that will be made and placed on it in the future. In fact, abutments are the point of connection between fixture and crown.
Therefore, in the single stage of surgery the implant itself or placement of the fixture inside the bone along with the gum forming screw is done at the same time.
In two-stage surgery، after implant insertion into the bone، the gum forming screw or healing is not immediately closed.
About two months after the fixture surgery, the surgeon checks the patient, and if the gums and bone of the surgical area are ready, then the gum forming screw or healing is closed.
This may re-incline a brief incision to the gum to access the fixture that is under the gum and inside the bone so that it can close the healing.
After doing this، he will wait about two weeks to a month before the gum returns to a more appropriate position and reverts to the desired form
Then the patient is referred to the prosist for implant molding until the delivery of the implant crown.
It is important to note that in regard to whether your implant surgery should be done in two or one stage, your surgeon will only make decisions depending on the bone and gum conditions in the area of the tooth and gum and determine the treatment procedure differently based on each patient's circumstances.
Implant Veneer Moulding
After the implant surgery, it takes about 2 months for the fixture to be grafted to the jaw bone, and after this time, if the gums and bones are fully formed and the surgeon approves the gum conditions, the patient is ready for the implant prosthesis molding phase.
And the delivery of the prosthesis is given. Implant molding begins and within a few sessions the mold prepared inside the patient’s mouth is tested to make corrections and formations, necessary investigations and evaluations are carried out.
And then in case of matching the crown with the implant and the approval of the prosthetic specialist, the implant crown is delivered to the patient.
When does implant treatment fail?
Physical and general health, number of extracted teeth, bone position and gum retention are all effective in implant surgery. For implant implant implants, the patient’s mouth should be free from any common dental caries and active periodontal diseases.
Contraindications of dental implant implants
Lack of integrity and bone graft during initial healing and infection of surrounding tissues are the reasons for implant failure.
There are few indications and contraindications for implant implants. In the case of prohibiting implant implants, we can refer to the following:
- Osteoporosis patients with severe osteoporosis
- Patients with uncontrolled epilepsy
- Children and adolescents who are of developmental age
- Patients with endocarditis
- Patients with a history of osteoradionecrosis
- Diabetic patients whose diabetes is not controlled
- Patients with uncontrolled cerebral artery occlusion
- Patients with a history of active bleeding
- Patients who have recently had heart transplants
- Patients who have vascular prosthetic surgery
- Patients with problems and diseases of the immune system
- Patients undergoing chemotherapy, radiotherapy
- Patients who have continued alcohol use
- Drug users
- Patients with major depression
- Patients with mental illnesses
It is important to note that one group of patients has an absolute prohibition on implant or any other surgical treatment, and that is patients taking injectable bisphosphonates such as zometa and denosumab.
What factors affect the success of implant implants?
Choosing the right fixture and material, the technique and skill of the surgeon in implant placement and observing the principles of mechanical use for an implant will lead to improved bone connectivity and prolongation of its life.
