A dental implant is a small screw usually made out of titanium, that replaces the root portion of a missing natural tooth. Due to the biocompatible properties of titanium, the dental implant fuses with the bone and becomes a secure anchor for the replacement tooth.
People in good health have the best chance for successful implants, but having health issues doesn’t automatically preclude patients from getting dental implants. Success rates of dental implants are lower in smokers, and chronic conditions such as diabetes can delay healing.
You need to care for your implants in the same way you do for real teeth – with diligent oral hygiene and regular dentist visits.
There are three parts involving an implant as illustrated below:
Dental implants are an option for people who have:
When you have a conventional dental bridge, the procedure involves crowning teeth at either side of the gap. Unlike a conventional bridge, dental implants do not affect the adjacent teeth.
When you have multiple teeth missing, an implant bridge can be used to fill the gap. The implants are inserted just like a single implant, and then an implant bridge is placed over the implants. The bridge is placed from one implant to the other implant, and there is no need to crown any of the adjacent teeth.
Option 1 - Conventional implants with zirconium crowns
In this option a full set of implants are recommended. This would require a maximum of eight implants on the upper jaw and a minimum of six implants on the lower jaw. Two sets of zirconium crowns are then placed on the upper and lower jaws.
Option 2 – All-on system implants with a click system acrylic cast denture
The second option is to have implants and a click denture system. Four implants are placed on the upper jaw and four implants are placed on the lower jaw. Then an acrylic cast denture is placed over the implants using a click system. The denture clicks on the implants, setting your dentures firmly in place. The denture can be removed without an effort, so the dentures are easy to maintain.
How Do I Know If I'm a Suitable Candidate for Dental Implants?
If you consider having implants, you must have healthy gums and adequate bone to support the implant. These are major factors affecting the success and outcome of the implant surgery. It is advisable to have an X-ray for the evaluation of your gums, teeth and bone prior to travelling abroad to have implants. This will help us in providing you with specific information on the details of the treatment including the duration and the cost of the treatment.
Implants may be contraindicated if a patient is taking intravenous or oral bisphosphonates as this may put a patient at a higher risk for osteonecrosis . Osteonecrosis is a bone disease which results from the loss of blood supply to the bone.
When a tooth is missing for a long period of time (even if you are using a removable denture), it leads to significant decrease in the strength and thickness of the jawbone, which is called jawbone resorption or bone loss. A dental implant is the only form of tooth replacement that prevents bone resorption. However, in order to successfully place the implant, there has to be sufficient jawbone.
If there is not enough bone, or if the tissue is too soft for the implant to be placed, bone augmentation is necessary. Bone augmentation is replacement of missing bone. Your dentist inserts artificial (synthetic) bone into the area where the implant will be placed. Healing time is usually six to eight weeks. After the healing period, implants can be placed.
Sinus lifting is required when there is insufficient bone available to securely place the dental implant. When upper back teeth are missing for a long period of time in the upper jaw, bone in that area shrinks or resorbs. Your sinuses expand to occupy the empty space where the bone used to be. The sinuses must be lifted in order to create space for placing additional bone in that area. The bone is added between your jaw and maxillary sinuses to make space for the implant.
Before having the procedure, a full oral examination will be performed by your dentist and oral surgeon. OPG (panoramic x-ray) or CT scan of the patient will also be evaluated before the consultation. These are used to analyse the density of the bone where the implant(s) will be placed. Local anaesthesia is adequate for this procedure as the only pain you experience is the prick of the anaesthesia needle and some amount of pressure.
Please remember to eat and drink fluids (non-alcoholic) as normal before the procedure, do not miss breakfast and take all of your medications at normal times.
Once your dentist is assured that your jawbone is healthy enough to receive an implant, the gum tissue is opened and a channel is created deep into the bone to place the implant with a special drill under local anaesthesia.
Depending on the density and anatomic structure of the bone your dentist will choose the type as well as the length of the implant. The implant is then placed in the channel and the gum is sutured or stitched back. In some cases, your dentist may not close the gum and place an abutment directly on to the implant.
If you already use a denture, you will continue to use it during the healing process, otherwise, a temporary prosthesis might be placed. Current dentures might be adjusted to fit better when needed.
The healing time is usually 3 to 6 months. During the healing period, the implant fuses to the bone and acts like a natural tooth root. Upon successful osseointegration, which is the structural connection that forms between your natural jawbone and the titanium implant, you move forward to the next phase.
The gum is re-opened to expose the implant. Then an abutment is screwed and tightened to the dental implant using special dental equipment. After this is done, a temporary crown is placed onto the abutment as the abutment needs to be protected from biting forces to ensure successful healing. The temporary crown is used for a few days until the permanent crown is ready.
In most cases, you need to visit Turkey twice to complete your treatment provided that you don’t suffer from bone loss.
1 st visit (surgery for the insertion of dental implants)
1 week, 1-3 appointments
Full integration between implant and jawbone (duration between the visits) usually takes 3 to 6 months, instant loading of the prosthesis over implants being possible in some cases.
2 nd visit (prosthesis over implants)
1 week, 3-5 appointments for zirconium bridges over conventional implants
10 days, 3-5 appointments for click system acrylic cast denture over all-on system implants
The implants serve the same function for both types of solutions, but the difference in the materials used to make the bridge over the implants significantly affects its final look, feel, and performance over time. A click system with a removable acrylic cast denture is used over allon system implants whereas fixed zirconium bridges are used over conventional implants.

We don’t recommend immediate loading in most cases as it is best to avoid stress on implants to let the tissues surrounding the implant heal properly to decrease the chances of failure for the treatment. If prosthesis over implants is inserted before the osteointegration completes, there will be gaps on either side of the implants increasing the chances of failure of the treatment. The risk of infection will also increase. It is best to wait a minimum of 6 to 8 weeks for the prosthesis over implants though temporary crowns can be made for the front teeth for aesthetic purposes.
Please note that any clinic that implements immediate loading will require a signed statement from you indicating that immediate loading is at your own risk.
Implants are most popular for patients who wear full dentures or partial dentures. They can be used to provide retention and support for a removable implant overdenture, which basically snaps on the implants eliminating dependency on denture adhesives. Dental implants can also be used for a fixed denture, where a patient’s dentures are bolted to the implants through titanium components.
