Who can not do dental implants?

A dental implant is a procedure in dentistry that can replace missing teeth with artificial teeth. This procedure is usually performed by an implant specialist. However, some people have restrictions on dental implants, which are mentioned below in some of the cases of creating these restrictions:

General medical problems

People with general medical problems may not be suitable for surgical procedures such as dental implants.

  1. Heart diseases: People who have heart diseases such as heart failure, cardiac arrhythmias, etc., may not be suitable for dental implant surgery. These diseases can increase the risk of cardiac complications due to surgery.
  2. Type 2 diabetes: People with type 2 diabetes may have bone density problems that can interfere with the process of implant acceptance. Also, diabetes can impair the healing process after surgery and increase the risk of infection.
  3. Immune diseases: People with immune diseases such as chronic inflammatory diseases, lupus disease, or systemic immune diseases may be at risk of infection and risk of complications from implant surgery.
  4. Blood problems: People with blood problems, such as hemophilia, have a higher risk of bleeding during and after surgery, which may affect the success of dental implants.
  5. Liver and kidney diseases: Improper liver and kidney function can have a direct effect on the healing process after surgery and cause serious complications.
  6. Previous surgery history: People who have had surgery in the past may not be suitable for dental implants due to problems with previous surgery.
  7. Taking certain medications: Taking certain medications, such as anticoagulants, immunosuppressive medications, and medications that affect bone density, can create restrictions for the implementation of dental implants.

Dental problems

Some people may have certain dental problems that make implant placement difficult or impossible.

  1. Lack of bone: For the success of dental implants, bone density in the implant area is very important. If there is not enough bone to accept the implant, it may be necessary to repair the bone using technologies such as bone graft.
  2. Oral infection: The presence of severe oral infections can weaken the healing process after implant surgery. Gum or oral infections should be controlled before dental implants.
  3. Gum diseases: Gum diseases such as gingivitis can lead to the destruction of gum tissues and bone in the implant area. These problems can have a destructive effect on the stability of dental implants.
  4. Gum problems: The presence of deep gum problems in the implant area can aggravate complications such as infections and prevent the success of dental implants.
  5. Crown/Bridge Treatment: If you have already had crown or bridge treatment, you may need to reconstruct and match the crown or bridge to the implant.
  6. Optimal size and position of the oral space: It is important to match the size and position of the implant with the oral space and other dental elements. Limitations in size and position can interfere with implant performance.

Finally, it is recommended that you consult your dentist before deciding to have an implant. By carefully evaluating your oral condition, they can guide you on whether the implementation of the implant is suitable or not and what steps and measures are needed for the success of the implementation of the implant.

Bone diseases and limitations in dental implants

Healthy bones with proper density are essential for implant acceptance. Below are some of the bone diseases and limitations associated with dental implants:

  1. Osteoporosis: Osteoporosis is a bone disease that leads to a decrease in bone density and weakness. People with osteoporosis may encounter problems in the stage of implant stabilization and acceptance due to the lack of bone density.
  2. Bone Cancer: People who are suffering from bone cancer or have had this disease in the past, may have limitations in terms of bone density and the ability to accept dental implants.
  3. Chronic bone diseases: Diseases such as ankylosing spondylitis, and osteomalacia can be included in this category. These diseases may affect bone density and limit the ability to use dental implants.
  4. Inflammatory bone diseases (Osteomyelitis): These diseases can lead to bone damage and inflammation. Inflamed bone cannot properly interact with the implant, undermining successful function.

Considering the importance of bone density and the general health status of bones for the success of dental implants, it is important to consult with a dentist specializing in bone diseases before deciding on dental implants.

Insufficient bone density and limitations in dental implants

Insufficient bone density can be one of the main limitations to the successful implementation of dental implants. Healthy bones with sufficient density are necessary to accept the implant. If the bone density is not sufficient, the implant cannot be properly fixed and remain stable in the mouth. In these cases, measures such as bone repair using advanced techniques may be required. Below I mention some solutions and measures related to insufficient bone density and dental implant limitations:

  1. Bone grafting: If bone density is insufficient, bone grafting or bone grafting can be useful. In this method, artificial bone or restorative materials are added to the implant area to increase bone density and provide a place to accept the implant.
  2. Sinus Lift: If the bone density in the area of the maxillary sinuses (where some implants are placed) is not enough, performing a sinus lift surgery can help increase the bone density.
  3. Use of shorter implants: If the bone density has limitations for implant implementation, you can use shorter implants. These types of implants are shorter than the usual length and are suitable for times when there is limited deep space in the mouth.
  4. Use of advanced technologies: Technologies such as three-dimensional radiography (CBCT) can help dentists evaluate bone density more accurately and plan more appropriately for implant implementation.
  5. Delay in the implementation of the implant: In some cases, the doctor may refuse to implement the dental implant until the bone density increases to the desired level.


Malnutrition and lack of vitamins and minerals can negatively affect oral health and the healing process after implant placement.

Therefore, before deciding on the implementation of dental implants, it is better to visit a dentist in Windsor specializing in dental implants to evaluate your exact situation and guide you.
