Dental implant

Dental Implant

If you have lost one or more teeth or have no teeth, you can use implants to replace the missing teeth.

Dental implant is a piece that is inserted as a root of the tooth into the jawbone and the crown is reconstructed on it.

Dental Implant

One of the advantages of implant is the lack of need for shaving the adjacent teeth, and therefore, it causes no damages to other teeth. Implants are known as the best solution for replacing missing teeth, since they look completely natural and have no difference from natural teeth and the patient feels completely comfortable when talking and eating.

What are implants made of?

Implants are usually made of different metals and ceramics with a structure similar to bones, which is compatible with body tissues. Implants are currently made of titanium metal.

How long an implant surgery takes?

This time will vary depending on different factors. The recovery time after surgery also depends on the restoration time of the individual’s tissues, however, with the advance of technology, this time has significantly reduced. On average, tissue healing and bone formation take about 2 to 3 months, after which the process of making the prosthesis (the crown) can be started.

What is the success rate of dental implants?

The success rate of implants depends on different factors, which vary in different patients. This rate is even different in maxillary and mandibular implants. On average, the success rate of dental implants has been reported as 95%.

How to take care of dental implants?

Your body’s health is critical to the success of the implant. Lack of oral and dental hygiene is considered as a major cause of implant loss. The use of dental floss and brushing at least twice a day are very important. Your dentist will teach you how to properly take care of the implant. In order to sure of the health of your gums, visit your dentist at least 4 times a year.

The steps of dental implantation:

The cost of having an implant:

In this regard, you should consult with your dentist. In many cases, this amount will not be much different from the cost of traditional treatment methods.

In short, implants are used in the following cases:

  • Replacing one or several teeth without involvement of adjacent teeth.
  • Implants can be used as a bridge base at the end of dental arches, so you don’t have to use removable dentures.
  • In cases that whole teeth are missing or large of number of implants cannot be used, implants can be used as the base for full dentures by placing ? or ? implants to keep your full denture from moving in your mouth and to make you feel more comfortable.

The advantages of using implants over moveable or fixed dentures (bridge)

At any angle you look at this, the use of implants is the best choice for replacing your missing teeth.

  • Cosmetics: The implant will look exactly like your tooth, and since it is fixed in your jawbone, it prevents bone and gum erosion, which is considered as one of the complications of the previous methods (denture or bridge). Anyway, no one will notice that you have a replacement tooth.
  • Preserving the structure of adjacent teeth: in this method, the adjacent teeth are not shaved and will not develop further caries.
  • Self-confidence: Using implants will certainly make you feel better about yourself, your laughing, and your talking.
  • Reliability: the success rate of dental implants is very high and they are the best choice for replacing your missing tooth. Despite past false claims in this regard, the success rate of implants is much higher than other tooth-replacement methods, and since the implant fixture is made of pure titanium, there will be no rejection of the implant.

Are there any complications after having an implant?

Since the implant fixture is made of pure titanium, there will be no transplant rejection, however, if the preoperative evaluation, which includes the following, is not carefully performed, the success rate may reduce.

  • Infectious diseases that weaken the immune system.
  • Uncontrolled diabetes
  • Being a smoker
  • Inadequate bone mass (in these cases, bone grafting can be done first, then implant therapy can be started)
  • Periodontal and gum diseases (in these cases, the gum disease should be treated first)

Implant radiography

Objectives of radiography

The objective of radiography is to obtain necessary information about the bone quantity, quality and angle, the relationship between the anatomic structures and the implant, and the presence of possible lesions in the surgical sites.

The phase two is done during the surgery (surgical and interventional implant imaging). This is performed to evaluate the surgical sites during the implant placement and right after it.

The phase three is done after prosthetic treatment (post-prosthetic implant imaging).

Implant surgery by two-stage procedure method

This method requires two surgical procedures:

First surgical procedure: the implant fixture is placed into the bone and completely covered by a mucoperiosteal flap, which is previously implanted. In the general term, in the first step, the implant is buried underneath the soft tissue.

Second surgical procedure: in this step, by performing a flap cover, we again remove the cover screw that was initially locked on the fixture and covered by a flap, and then, we place the healing abutment and stitch the flap around it.

The advantage of this method is that the bone healing process takes place without the presence of any forces on the implant fixture until the restoration process is carried out.

Implant surgery by single-stage procedure method

This method only requires one surgical procedure.

Similar to the two-stage procedure method, pulling the flap over provides a sufficient view and direct access to the bone. In this method, the permucosal extension element (PME) is placed slightly above the bone crest.

Advantages:

  • Maturation of soft tissue at the same time with hard tissue
  • No need for second-stage surgery

Implant surgery by direct single-stage method (flapless procedure)

In this method, the soft tissue of crestal bone is not pulled over, but instead, cylinders of keratinized tissue in the size of the diameter of implant crest module are removed from the crestal bone, so no stitches are required in this method. However, one of the main disadvantages of this method is the surgeon’s inability to estimate bone mass before osteotomy or during implant placement. So it seems obvious that the surgeon is only allowed to use this procedure when the patient has a bone width greater than 8 mm and enough keratinized gingiva.

summary and overview of implant surgery

implant surgery can be performed under local anesthesia or anesthetic nerve block, and general anesthesia is required in extensive implant surgeries. Before the surgery, the surface of the skin around the patient’s mouth and lips must be disinfected by betadine, and the patient should wash his/her mouth with chlorhexidine mouthwash for 2 minutes. The use of anti-preoperative anxiety is mandatory for patients with severe anxiety, and Benzodiazepine 5mg can be administered the night before surgery and one hour before it. Also, in patients who need antibiotic prophylaxis, antibiotic prophylaxis should be carried out before implant surgeries and according to the standard protocol.

The level of pain in dental implants

Since dental implant surgery is carried out under local anesthesia, the patients will have no pain during the surgery. However, after the surgery depending on the duration of the dental implant surgery and the patient’s bone quality and tissue response, some pain and swelling are expected, which can be minimized by administration of medication before and after the surgery.
