Is there a disease or physical condition that affects implant placement?

These questions are frequently asked by patients who have lost one or more teeth and intend to have an implant. There are many other questions according to the conditions and diseases that each person has,

such as whether smokers can also have dental implants?

Can I have a dental implant if I have diabetes?

Does pregnancy affect dental implants?

In general, it can be said that 95% of people who have lost one or more teeth can have dental implants without worrying about losing them in the long run. However, there are a few specific diseases and conditions that may cause the dental implant to fail. In such cases, you are a bad candidate for dental implants!

Uncontrolled diabetes dental implantsUncontrolled diabetes

One group of patients who cannot have dental implants is those with uncontrolled diabetes. Many people with type 1 or type 2 diabetes who control it with medication or insulin injections, that is, their blood sugar is under control and does not fluctuate, have no problem with dental implants.

Note that dental implants are not only safe for diabetics, but dental implants can also help keep their mouth, teeth, and heart healthy.

However, there are limitations to dental implants in people with uncontrolled diabetes because it can cause gum disease or infection after the implant. These patients can also have dental implants after regulating blood sugar through medication and lifestyle changes.

Pregnancy dental implantsPregnancy

Pregnancy is one of the limitations of dental implants. If you have lost one or more teeth before or during pregnancy, you should not rush into a tooth implant. All dentists advise pregnant women to postpone dental implants until their baby is born. The following are some of the main reasons why pregnant women should not have dental implants:

  • Risk of surgery: Although dental implants are an outpatient procedure, it is still a surgical procedure and it is best not to put your fetus at risk. Of course, dental implants themselves are not prohibited during pregnancy, but if you need to take emergency medication, the health of the fetus may be endangered.
  • X-rays: You should avoid X-rays during pregnancy. X-rays must be taken before a dental implant can be made. X-rays of the teeth may increase the risk of preterm birth.
  • Use of anesthesia: Although a number of studies show that treating teeth with local anesthesia during pregnancy is safe, it is best to avoid any medication that reduces your consciousness during the critical period of pregnancy.
  • Increased stress: Increased stress and anxiety in pregnant women can adversely affect fetal growth. Performing any type of surgery puts a lot of pressure and stress on you, which causes the secretion of stress hormones. Relaxation and concentration are essential for the growth of the fetus and you should not have any stress or anxiety during pregnancy especially for unnecessary surgeries. Therefore, it is better to postpone dental implants until the birth of your child.
  • Better crown molding: Dentists recommend that you visit for a dental implant after the postpartum recovery period. The postpartum dental implant will be of much better quality because you may have swelling during pregnancy due to edema and the crown molding that is done for you during pregnancy may not be perfect. After delivery and breastfeeding, the structure of your jaw and gums will return to normal and the designated crown will be better placed on the implant and you do not need to worry about it loosening.

Heart related conditions dental implantsHeart related conditions

Other restrictions on dental implants include a history of heart attack or heart surgery over the past six months. In this case, it is better for the patient to postpone the dental implant until his/her physical condition returns to normal. Usually, people with a history of heart attack should consult a cardiologist about dental implants. Also, patients who have irregular and uncontrollable heartbeat cannot have this dental treatment.

Note, however, dental implants have also been performed successfully on patients who have had bypass surgery or any other kind of heart surgery or who have had a heart attack in the past; Only these patients should check and control their physical condition and not have stress and anxiety at the time of dental implant. Relaxation during implant placement has a great impact on its success rate.

Osteoporosis dental implantsOsteoporosis

Because the base of the dental implant is screwed into the jawbone, bone strength is critical to the success of this treatment. In people with osteoporosis, bone healing occurs very slowly, therefore, the osteointegration process (implant fusing to the jawbone), which plays an important role in the success of dental implants, may fail.

Also, these patients take high-dose bisphosphonate medications for weeks or months. Bisphosphonates increase the risk of bisphosphonate-related osteonecrosis of the jaw (BRONJ). The most common bisphosphonate-containing drug is Fuzamax and is prescribed for people with low bone density or people with bone cancer. That’s why dental implants are so challenging and sometimes impossible in people with osteoporosis or bone cancer.

Chemotherapy and radiotherapy dental implantsChemotherapy and radiotherapy

Radiotherapy can limit the use of implants especially on the back of the jaw and have an adverse effect on implants outcome. Therefore, patients undergoing radiotherapy, especially in the maxillofacial area, are advised to postpone dental implants until the end of treatment. Because radiotherapy has toxic effects on oral and dental tissues and may delay the healing of gingival tissue after dental implant placement.

Patients undergoing chemotherapy also have lower immunity, which is why they are more at risk for infection after dental implants. Therefore, patients undergoing chemotherapy or radiation therapy are advised to treat their oral conditions only in very urgent cases. Doctors warn people who intend to have a dental implant in less than three months after the end of their chemotherapy and less than six months after the end of their radiotherapy because of the possibility of implant failure and also Infection of their gingival tissue. Of course, after the end of these treatments and passing the recovery period, it is possible to have a implant.

Immune system diseases dental implantsImmune system diseases

Other people who cannot have dental implants are those with immune system diseases. Immune system diseases are those in which a person’s immune system is weak or the immune system attacks and destroys its own tissues. Almost anyone with a very weak immune system cannot get a good result from the basic implant placement in their jawbone. Leukemia, AIDS, and MS are some of these types of diseases.

Smoking dental implantsSmoking

Smoking is not only one of the major causes of tooth loss but it can also limit the use of dental implants and have an adverse effect on dental implants. Studies of smokers show that the success rate of implants in these people is 15% lower than in non-smokers. Also, the risk of gum infection after this treatment is very high for smokers. Therefore, it is recommended to refrain from smoking until the dental implant is completely fused.

Age limit dental implantsAge limit

Loss of one or more teeth at any age can occur. There is not a minimum or maximum age to implant a missing tooth. All people who are in good general health and have healthy gum tissue and jawbone can have a dental implants.

But it is better for adolescents and children to postpone implants until the end of their growth so that their jaws stop growing. This reduces the chance of the implant being loosened and increases its success rate.

implants are not usually performed on people under the age of 18, and the dentist recommends that the patient wait until their jaw is fully developed.

Also, there is no maximum age for implants, so many older people resort to implants to get rid of troublesome dentures, which is more than 95% successful.
