History of Dental Implants
Implantology, the dental specialty concerned with the placement of dental implants, is one of the oldest methods in dentistry, following oral and maxillofacial surgery. The use of root-form implants dates back several thousand years.
Around 4000 years ago, in ancient China, bamboo was used to replace missing teeth. About 2000 years ago, in ancient Egypt, precious metals were used for the same purpose. In some mummies discovered in Egypt, researchers have found human tooth transplants, serving as evidence of the ancient practice of dental implantation.
In 1952, a Swedish orthopedic surgeon named Per-Ingvar Brånemark, who had a strong interest in bone repair and regeneration, discovered during his research on rabbit femurs that bone could grow around titanium metal. Brånemark continued his studies on both animals and humans, and after numerous experiments, successfully proved this beneficial property of titanium.
Although Brånemark initially worked on the femur, he later decided to continue his research in the field of the mouth, as he felt there was greater accessibility and need in this area. In 1965, Brånemark placed the first dental implant in the jaw of a volunteer patient.


What is an Implant?
A dental implant is a prosthetic device that replaces a patient’s natural tooth with an artificial one in the mouth. Today, dentistry describes dental implants as the art of replacing missing teeth. Implants are used to replace one or more missing teeth and to support and provide retention for complete dentures (overdentures). Dental implants are made of titanium and integrate with the bone through a process called osseointegration.
After initial examinations, the fixture—also known as the root part of the prosthesis—is surgically placed into the jawbone during a minor surgical procedure, at the location of the missing tooth. Following this, after ensuring its stability—which usually takes about 4 to 6 months—the upper part, known as the crown, is attached. If a person loses a tooth, an implant of the same root size is placed in its position.
Implants are made in sizes similar to natural teeth. They are manufactured using highly precise tools and equipment. Due to these characteristics, once a dental implant is placed in the patient’s jaw, it is not considered a foreign body and becomes biocompatible with the surrounding tissue. Additionally, implants stimulate bone growth around the area and help prevent the resorption or deterioration of the jawbone.

Stages of Dental Implant Procedure
Step 1: Examination, consultation, and treatment planning by the dentist

Step 2: Taking radiographic images and specialized CT scan (C.B.C.T)
Then confirming the suitability for implant placement based on the scan, jawbone condition, sinuses, nerves, and the patient’s overall health.




If the patient’s gums lack sufficient strength, a bone grafting procedure must be performed. In such cases, implant placement can be done either simultaneously with bone powder application; however, taking impressions and placing the crown will be carried out approximately 6 months later. Alternatively, if the implant is not placed at the same time as the bone graft, it is necessary to wait between 6 to 8 months before proceeding.

If necessary, implant placement is performed three months after tooth extraction. (Usually for molar teeth)

Two types of implants used in the specialized clinic of Dr. Hamed Keramat


Stages of Immediate Dental Implant
Dental implant placement in the immediate method is performed in a single session.
In this technique, the tooth root is extracted in one session, and the implant is placed simultaneously — all in the same visit. One-day implants are usually used for front teeth and only when the jawbone is in optimal health and condition.
In a follow-up appointment, a temporary crown is placed over the implant. After the implant has fully integrated with the jawbone (a process called osseointegration), the temporary crown is replaced with a permanent one.
All stages of the immediate implant procedure are otherwise similar to those of a conventional dental implant.

With the difference that all stages are completed in a maximum of two sessions.
Stage 7: Attaching the Titanium or Zirconia Crown to the Abutment
A titanium or zirconia crown is connected to the abutment. In most cases, the crown is temporarily cemented in place. This allows the surgeon to easily remove it if any signs or symptoms of inflammation around the implant are detected, so that necessary actions can be taken to resolve the issue.
