Dental implants can restore teeth in most cases of tooth loss, providing chewing function and aesthetics like real teeth. However, some people with health problems or insufficient jaw bone density will not be able to have implants. This article will help you better understand who should not get implants and why you should avoid this method.

1. Children and people under 18 years old

According to research from the National Institutes of Health (NIH), the majorityChildren and people under 18 years old are not eligible for dental implantsbecause the jaw bone has not fully developed in both shape and structure.At this age, bone density is often low, unable to ensure the stability necessary to maintain long-term dental implants.

If done intentionally, the dental implant is at risk of becoming loose or tilted as the bone continues to grow. To better understand the problemCan children have implants?, you can refer to more information shared by the team of doctors at Lac Viet Intech Dental Clinic.

People under 18 years old often do not have enough jaw bone density to receive implants

In cases where children cannot have dental implants, there are a number of temporary replacement methods to help ensure chewing function and aesthetics:

  • The function holds the interval: Is a solution to preserve the space of missing teeth, ensuring space for permanent teeth to grow in the correct position. However, space maintainers do not provide much support for chewing ability and need to be changed as the child grows older.
  • Bridge the glued wing: This method uses a row of dentures fixed to real teeth on both sides of the gap through specialized glue. The advantage of plywood bypass is that it is less invasive and highly aesthetic. However, the durability is not too long and requires thorough cleaning to avoid damage to real teeth.

Children need to wait until the jawbone is completely developed (usually after age 18) to consider itdental implant. During this time, temporary solutions like the above will help protect oral health and limit problems that arise. In addition, the reference implant simulation will help you have a deep understanding of this solution and should proceed with dental implants after the age of 18!

If children are not old enough to have dental implants, they can use alternative measures to prevent complications from long-term tooth loss.

2. People with mental disorders

People with mental disorders are not suitable for implants, especially those who are in the treatment phase or are often in a state of stress.. The reason is that patients often lose mental control, making it difficult to cooperate with doctors and affecting the treatment process.

If you still try to get an implant, the patient may encounter problems such as unstable dental implants, severe infections, and abutment rejection due to not following the doctor's instructions on the special care needed after implantation. Therefore, people with mental disorders should use temporary and easy-to-use dental restoration methods such as removable dentures or space maintainers to temporarily restore chewing function and aesthetics.

According to the National Institutes of Health, bPatients should continue psychological treatment and only consider implant surgery when they are mentally stableand can coordinate effectively with doctors throughout the treatment process.

People with mental disorders or excessive stress are often recommended by doctors not to get dental implants until the disease is completely controlled

3. Pregnant women

Pregnant women should not have dental implants because this process can affect the health of the mother and fetus.Dental implants require procedures such as X-rays to evaluate tooth condition and jaw bone density. Although modern X-rays have a high level of safety, there is still a potential risk of affecting fetal development.

After implantation, doctors often prescribe painkillers and antibiotics to aid the recovery process. However, these drugs can adversely affect the development of the fetus, especially during the first or last 3 months of pregnancy. If you try to have dental implants during this period, pregnant mothers may experience complications such as infection or prolonged pain, affecting the overall health of both.

To ensure safety for both mother and baby,pregnant women should delay dental implants until after giving birth and their health is completely stable. In the meantime, pregnant mothers can consider using removable dentures or temporary replacement methods to ensure chewing function and aesthetics.

If you are concerned about the cost of dental implants, you can refer to the article "How much does an implant cost" for the most detailed and accurate information.

4. Heavy smokers

Smokers have a high risk of experiencing complications after dental implants, such as gingivitis and swollen dental implants due to the effects of nicotine and toxic substances.Nicotine constricts blood vessels, reducing the amount of blood and oxygen supplied to the implant area, making recovery difficult. Toxic substances in cigarette smoke also increase the risk of inflammation. gums, swelling and infection.

According to research by Mustapha A. D., Salame Z. & Chrcanovic B. R. (2022) published inMedicina, the risk of dental implant failure in smokers is 140.2% higher than in non-smokers. As a result, dental implants may not integrate well with the jaw bone, leading to loosening or having to be removed reduces the lifespan of dental implants and increases the risk of recurrence of diseases around the teeth.

To ensure effectiveness and safety when implanting teeth,smokers need to stop smoking at least 1 month before and 2 - 6 months after implantationThis is a necessary period of time to help ensure an ideal environment and healing conditions for the implant area, reducing the risk ofcomplications when implantingIn case of difficulty quitting If you smoke tobacco, you should consult a doctor or specialist for effective smoking cessation instructions before proceeding with treatment.

5. People with chronic diseases do not control their condition

To have a successful dental implant, people with chronic diseases such as diabetes, high blood pressure or cardiovascular diseases need to control their health well.If these diseases are not controlled, dental implants can be risky. Specifically, dental implants should not be performed when:

  • Blood pressure is too high: Blood pressure > 150/90 mmHg increases the risk of bleeding and other complications during surgery.
  • Uncontrolled diabetes: Blood sugar levels > 10 mmol/l can affect wound healing and increase the risk of infection.
  • Other underlying diseases: Without the permission of the doctor treating the underlying disease, implants cannot be performed to ensure safety.

When the above diseases are controlled and your health is stable, you can have dental implants. Also, if you don't know Can dental implants have braces? Please ask your doctor for detailed answers!

6. People with insufficient jaw bone density

People with insufficient jaw bone density may have difficulty getting implants because the bone is not stable enough, reducing the ability of the implant to integrate.This condition often occurs due to long-term or congenital tooth loss.

Normally, doctors will prescribe bone grafting to increase bone density, creating favorable conditions for implant placement. However, in some special cases, if the bone condition cannot be improved (due to reasons such as poor health or a bone location that cannot be operated on), the doctor may recommend other dental restoration measures. In these cases,dental implants for the elderlywill require careful consultation and proper preparation by a doctor.

To have an accurate diagnosis and find the optimal solution, you should visit reputable dentists so that the doctor can provide appropriate treatment and advice.

7. People suffering from dental diseases

Dental diseases such as tooth decay, periodontitis and gingivitis can seriously affect the implant process.For example, periodontitis causes inflammation of the gum tissue, causing loss of tooth adhesion, directly affecting the stability of dental implants. If not treated promptly, bacteria from inflamed tissues can enter the area around the dental implant, causing infection and leading to implant failure.

People with dental diseases need complete treatment before undergoing dental implants. If the implant is implanted when the oral condition has not improved, it can cause complications such as infection, disruption of the implant's integration into the bone, or even rejection.
