Implant crown problems

Implant crown problems: Although it is rare for a dental implant to break or loosen, even if your dentist takes all precautions and uses the most advanced technology, you may experience this problem. Dental implant failure can happen due to the lack of adaptation of the body to the organ transplant or due to the general health of the patient and the surgical process or post-operative care.

A dental implant can be one of the best ways to replace a missing tooth. Even when you have lost two or more teeth, with the help of an implant, it can be restored to its natural state. But dental implant falling and implant coating loosening are one of the problems of dental implants. In some cases, the tooth crown falls after some time, which causes people to worry. In this article, we intend to investigate the cause of this problem. So, stay with us until the end of this article.

Implant crown problems, why do dental implants loosen?

The implant process may fail for various reasons. Implant crown problems and the cause can be before the crown is placed or after the crown is placed.

the failure of implant surgery happens in two times:

  • Before the metal base is grafted to the jaw bone
  • After placing and welding the abutment (connecting the crown to the fixture or base) to the jaw bone and placing the crown

The cause of the failure of the implant before the application of the crown is the lack of fusion of the base with the bone, which can be affected by several factors. However, the causes of failures after placing the prosthesis are caused by excessive pressures that the implant can withstand (non-physiological pressures). For example, the incoming forces caused by grinding teeth or not properly integrating the implant with the metal base, breaking the crown, using low-quality materials to make the crown, etc. will damage this surgery. Note that severe pain or discomfort and swelling or inflammation of the gums will be complications of implant failure. In the following, we will explain more about the symptoms of implant loosening and its reasons.

Note that if this operation fails before the metal base is grafted to the jaw bone, the maxillofacial surgeon will place the base in the gum during a re-examination and the crown will not be placed on it until complete recovery.

The main reasons for dental implant failure and loosening

Two main reasons may cause dental implants to fail:

  • peri-implantitis
  • bone fracture

Peri-implantitis occurs when teeth are not properly cared for by regular brushing and flossing. Peri-implantitis is a type of gum disease in which the infection damages the bone. If not diagnosed immediately, this disease can cause tooth loss.

Bone failure occurs when the jawbone near the implant cannot protect it. This reason depends on the quality of the bone. When the implant is not properly seated in the bone, it usually happens in the early stages after surgery, and the implant breaks and loosens.

Failure and primary problems of dental implants

Implant crown problems: The initial stages of failed dental implants occur three to four months after surgery. The dentist must proceed according to the principle. including sterilization, prevention of bone overheating, flap technique, fixed placement, and finally placement of implants where there is sufficient bone. Keep in mind that even if you have seen a professional surgeon, not all implants will integrate with the jaw despite accurate measurements. Reasons that can cause dental implant failure include:

  • Poor blood supply to the implant area
  • Oral infections
  • Implant movement during recovery
  • Failure to provide sufficient time for implant integration
  • The weak immune system of the patient

Late tooth failure may occur 1 to 10 years after surgery and may include:

  • Strong pressure on the implant
  • Lack of gum tissue
  • Radiation to the head and neck
  • Food remaining between the implanted teeth

While peri-implantitis and failed osseointegration are the two main causes, other reasons for failure can include:

Infection occurs during or after dental implant surgery. Risk factors for this include having an autoimmune disease, being a smoker, and having poor oral and dental hygiene.

  • Insufficient jaw bone

Failure can occur if there is not enough jawbone to attach the implant to, as the bone holds the tooth and the implant fuses with the jaw. In most cases, if there isn’t enough bone, people get bone rejuvenation before surgery.

  • Inconsistent oral hygiene practices

If you don’t brush twice a day and floss once a day, it can lead to peri-implantitis and other gum diseases.

  • Placement in the mouth

Improper placement by the surgeon can affect the outcome. This surgery requires an experienced and trained dentist to first understand your condition and take precautions during the placement process.

  • Pre-existing medical conditions, including cancer

People with chronic diseases such as diabetes, autoimmune diseases, cancer, and osteoporosis may be at higher risk for implant failure.

  • Having diabetes
  • Taking some medications
  • Poor implant placement
  • smoking
  • Grinding teeth

Keep in mind that you may experience some degree of pain or discomfort after dental implant surgery, which can be controlled with pain medication. However, if the pain does not improve after 5-7 days, you should talk to your dentist.

The cause of pain and swelling after the implant

While pain and swelling are common after surgery, they may be caused by:

Micro-movement of the implant: This happens when your implant is not stable. The surgeon immediately connects the artificial tooth to the implant.

Inadequate bone support: Failure of the implant may occur if you do not have enough bone to support the implant.

Allergic reaction: If you are allergic to titanium alloy, you may experience swelling, loss of taste, or tingling, in which case the implant should be removed. If you have allergies, be sure to discuss this with your dentist beforehand.

Failure to follow the doctor’s instructions to reduce the risk of complications: You should follow the post-surgery care recommendations, which include eating soft foods until the implant site heals, avoiding hard foods, and maintaining oral and dental hygiene.

Implant crown problems: the cause of falling and loosening of the implant crown

After a time, you may notice that the crown of the implant loosens and loosens. Many reasons cause the tooth crown to fall after a while and the implant to lose its beauty. Note that knowing these causes can prevent further problems including infection and gingivitis. the reason for the implant not being installed and falling is:

1. Inconsistency of the implant with the jaw bone

One of the most important challenges of implantology is the placement of the titanium base inside the jawbone. This should be done in such a way that this metal base is surrounded by the bone. If the dental implant surgeon does not have enough experience and expertise in this work, he is not able to diagnose the condition of the bone.

the condition of the bone should be checked first in terms of the position for dental implants. Sometimes the patient’s jaw bone is not suitable for this work.

When the implant is not aligned with the patient’s jawbone, the crown also looks unnatural. After some time, the gum will decay and the silver metal of the titanium base will be seen around the gum. It is a bit difficult to correct implants that are not placed in the right place and ideally on the bone. On the other hand, removing it may damage the adjacent bone and teeth

2. Oral and facial misperceptions from examinations

Before the dental crown is placed on the healing screw and abutment (metal base), the patient’s tooth is first molded. The size of the crown should be determined in advance and then this mold should be sent to the laboratory.

Of course, it is not only the appearance of the teeth and smile design that is ruined. Rather, over time, bacteria enter the gums and lead to gum abscesses. On the other hand, a crown that is too big will damage the adjacent teeth. A small crown can also damage the implant tooth. As a result, it is moved from its place over time, which leads to the falling of the crown.

3. Gum inflammation and infection

Another reason for the loosening of the implant crown is infection and gingivitis. In terms of dental science, this complication is called “peri-implantitis”, which is one of the main reasons for dental implant failure. In this condition, the gums and jaw bone become severely infected and inflamed. The reason is the formation of harmful bacteria in the mouth.

Peri-implantitis can damage the bone and gum around the implant. so that it loosens the crown of the implant and the healing screw and causes it to fall after a while. Although this disease can be treated and if you see the relevant specialist on time, its consequences can be prevented. One of the causes of peri-implantitis is a lack of health care, smoking, or diabetes.

4. Premature laying of the crown

It usually takes a few weeks to a few months for the fixture to bond with the jawbone. Sometimes the metal base does not integrate with the jawbone even after several months. This causes the implant to loosen and even destroy it. Examining the bone density and the overall health of the patient’s jawbone is a topic that few implant surgeons ignore.

if the jaw bone is not enough, the conditions for implant implantation should be provided by bone grafting and other necessary methods.

5. Nerve damage to the implant

The treatment plan is what helps the dentist identify all the factors that cause the dental implant to fall out. For example, it becomes important to determine the ideal place to place the metal base on the nerves and oral tissue. Damage to the oral nerves causes numbness and long-lasting pain, tingling sensation around the gums, cheeks, and tongue. Addressing these issues will prevent implant failure.

6. Loosening or breaking of the metal base and implant crown

Although the abutment and healing screws are made of strong metals, they may loosen in place. The movement of the metal base also causes the crown to collide with the surrounding teeth and eventually break. Now, thanks to the advances in implant technology, this cause of dental implant falling out is rare.

But the implant crown is often made of poor-quality materials that break very quickly. To make an implant crown, which is also considered a type of prosthesis, high-quality materials must be used that can resist chewing and even unwanted teeth grinding. Using the best materials can prevent this problem.

7. Allergic reaction of the implant to some materials

Sometimes the cause of dental implant falling is due to an allergic reaction in the body. On the other hand, chewing hard food or breaking snacks and candies, etc., with implant crowns will damage it a lot. Even when first-class materials are used to make dental crowns, there is a possibility of lip filling in such cases. To avoid this problem, the only way is to take care of implanted teeth like natural teeth. Maybe it’s better to say that you should take care of the implant more.

8. Implant crown problems: failure and late complications of dental implants

Even if your dental implant surgery was successful, you may experience complications years later. Here are some long-term side effects that can occur:

Placement of the implant near the nerve of the tooth: When your surgeon places the implant too close to the nerve, nerve or tissue damage can occur. Symptoms include numbness of the tongue, lips, gums, or face.

Non-acceptance of the implant by the gums: symptoms of this event include increased pain at the treatment site, swelling, fever, and chills.

Protrusion of the implant into the sinus cavity: It happens when the implant is placed in the upper jaw.

Damage to the area around the dental implant: may cause it to loosen and thus break.

To minimize the chance of long-term implant failure, always maintain good oral hygiene and visit your dentist regularly for regular checkups.

Screw crown loosening

Another problem with the implant crown is the loosening of the screw crown. This is a small screw that is placed on the jawbone after the fixture is in place so that it can completely crown the surface of the fixture. This piece prevents contamination, bacteria, blood, and gum tissue from entering the fixture. Note that this part must be placed on the implant until the second stage of the surgery, i.e., the closing of the healing on the fixture. In some people, the poor quality of implant components with a lack of care and oral hygiene can cause movement or loosening of the screw crown. Note that if you notice that this piece is loose, see a doctor quickly to prevent further complications.

The following reasons can be mentioned for the implant cap falling:

  • Implant placement with external connection
  • Low torque for screwing the abutment
  • Failure to manage teeth grinding or tooth wear
  • Bone profile around the implant
  • Loosening of the healing cap
  • Improper implant screw selection
  • Improper implant screw size
  • Unexpected loosening of the abutment screw

What to do if the dental implant falls?

First, we suggest you visit dental specialists for implants. Professionals can treat peri-implantitis by cleaning your implant. If you get this disease, focus on good oral hygiene. If you have an injury or pressure on the bone, the first step is to remove the inflamed tissue near the implant. Bone grafting may also be vital. In addition, depending on the extent of the damage in the mouth, you may need to remove and replace the crown.

After loosening the implant crown, the reason must be determined first. For this, visit the maxillofacial specialist where you had the implant done. If you get peri-implantitis after tooth implantation, it is necessary to treat the infection with antibiotic drugs. In these cases, the faster you see a specialist, the faster the infection and inflammation can be controlled.

Even if the fall of the dental implant has damaged the bone around the implant, it can be treated. Of course, for the treatment, the maxillofacial surgeon may use the method of bone removal and bone replantation.

This can also be treated if there is damage to the bone around the implant. But the treatment involves removing the bone and then doing a bone graft to put the implant back in place.

How to know if the implant is loosening?

Several signs can help you know when an implant is loosening. A feeling of severe pain inside or around the implant or swelling and inflammation of the gums indicate the failure of the implant.

How to minimize the possibility of dental implant failure?

Implant crown problems: The thought of dental implant failure can be worrying. However, the following guidelines can help reduce the risk of dental implant failure:

  • You can relieve swelling and discomfort after dental implant surgery in a variety of ways.
  • Avoid vigorous activity for at least 48 hours after surgery. Because a high heart rate can increase bleeding, discomfort, and swelling. It is recommended to refrain from performing heavy tasks or exercise for a few days.
  • Avoid aspirin and other blood thinners.
  • Some over-the-counter pain relievers and herbal supplements may affect blood clotting and cause more bleeding. Patients should visit their dentist to ensure that they are taking the safest medications after implant placement.
  • Ice compresses can be used to help reduce swelling.
  • If using an ice compress. After 15 minutes, remove the ice pack and wait another 20 minutes. Intermittent use of ice compresses can help reduce inflammation and pain.
  • Be careful that all medications must be taken exactly as prescribed.
  • The dentist may prescribe medications such as pain relievers and antibiotics. In addition, they may recommend over-the-counter medications to reduce discomfort and swelling. To minimize pain and other side effects, patients should follow the diet prescribed by the dentist in Mississauga.
  • Avoid eating foods that are too crunchy, too hard, or too hard.
  • It is recommended to avoid eating nuts and popcorn and use a soft diet after surgery.
  • Observe oral hygiene.
  • While brushing and flossing at the implant site may be difficult for several days after surgery, it is important to keep the area clean. Typically, the dentist will recommend an antibacterial mouthwash to prevent the spread of dangerous bacteria.

Do dental implants fail?

Before getting an implant, many people ask their doctor if the dental implant will break. In answer to this question, it should be said that the idea that the implant is artificial should not mislead you that these teeth do not suffer from damage and decay. You should take care of the implant just like you would a natural tooth. Considering the high price of dental implants, maintaining oral and dental hygiene, refraining from smoking, controlling diabetes, and visiting the doctor regularly can increase the useful life of the implant.

Dental implants provide a strong, safe, and durable foundation for the tooth. If you have experienced tooth loss and want to know more about minimizing the risks and complications of dental implants, it is better to consult an experienced dentist before taking any action.

Considering the problems that may occur as a result of the dental implant falling out, our advice is to be more careful in choosing an implant surgeon from the very beginning.
