Introduction

The implant abutment is one of the key components in the dental implant process. In this article, we examine the concept, types, materials and applications of implant abutment.

What is an abutment?

Abutment is an intermediate piece between Dental implant And prosthesis (artificial tooth) is placed. Its main task is to transfer the chewing force to the implant and provide a suitable surface for connecting the prosthesis. In addition to transmitting the chewing force, the abutment has the task of providing stability. prosthesis is also responsible for Also, the abutment can act as an intermediary to connect different prostheses (such as Crown, Bridge, or Denture).

Types of abutment

Standard abutment

This type of abutment is manufactured in a prefabricated and standard form and is suitable for many implants. Standard abutments can also be classified based on height and angle.

Custom abutment

This type of abutment is specially designed and made for each patient. This option is especially useful for more complex and unusual cases.

Angled abutment

This type of abutment is designed to angle the implant and is suitable for situations where the teeth are at an unusual angle. Angled abutments are better defined as universal because they are used in limited and specific cases and may lead to less stability.

Material of implant abutment

Abutments are usually made of a variety of materials, including:

Titanium:

The most common material for abutments, which is known for its high compatibility with the body and good strength. Titanium processed in two forms (for example, pure titanium or Tial (Titanium-aluminum) and …) can have differences in compatibility and strength.

Ceramics:

It is used for cases where appearance is more important. This type is especially popular in front teeth.

Metal alloys:

Some abutments are made of special metal alloys that help with strength and durability. There are also carbon fiber and newer and more advanced materials that can be used in some applications.

Applications of implant abutment

Transmission of chewing force

The abutment helps to distribute the chewing force and prevents damage to the implant. The abutment can also play an important role in communicating between the prosthesis and the soft tissue (gum).

Creating a suitable surface for the prosthesis

This piece provides a space for placing the prosthesis and improves its beauty and function.

Adjusting the height of dentures

Abutments can help adjust the height of artificial teeth to match natural teeth.

The role of abutment in dental implants

The role of abutment in dental implant is very important and in fact abutment acts as an intermediary between implant (screw) and dental prosthesis. The abutment is usually made of biocompatible materials such as titanium or zirconium, and its main functions include::

Power distribution:

The abutment helps distribute the mechanical forces applied to the dental prosthesis and prevents direct loading on the implant..

Transmission of biological signals:

The abutment provides an environment for bonding with the gingival tissue and acts as a substrate to improve the biological function of the implant..

Build strength and stability:

The abutment must be strong enough to hold the denture while still allowing the denture to fit easily into place..

Customization:

Abutments are usually custom designed to fit the patient’s oral anatomy and the type of prosthesis..

Access to the implant area:

By using an abutment, it becomes easier to access the implant area to fix possible problems or prescribe the necessary treatments..

In general, abutment plays a key role in the stability and efficiency of dental implants and helps to improve the quality of life of patients.

Advantages and disadvantages of implant abutment

It is called a structure that is used in dentistry as a base for placing dental prostheses, veneers or bridges. The use of abutments has advantages and disadvantages, which are mentioned below:

Advantages:

Preservation of natural tooth structure: Compared to artificial teeth, abutments cause the least damage to natural teeth.

Stability and strength: Abutments can provide a solid foundation for prostheses or bridges, which increases their efficiency and stability.

Aesthetics: Abutments can be matched with neighboring teeth and achieve a natural appearance.

Pressure transfer: Abutments transfer the loads caused by chewing to the jaw bone and thus prevent bone loss.

Facilitate the installation of prosthesis: In cases where a person needs to replace a large number of teeth, abutments can facilitate the prosthesis installation process.

 

Disadvantages:

Need surgery: Installation of abutments usually requires surgery, which may be uncomfortable for some patients.

Risk of infection: Any type of surgery may be associated with the risk of infection, and abutments are no exception.

cost: The cost associated with installing abutments and prostheses may be high and unaffordable for some patients.

Need to maintainAbutments and prostheses need care and maintenance to prevent complications such as infection or bone loss.

Probability of failure: In some cases, the body may react negatively to the abutments and as a result, they may not function properly. Considering these advantages and disadvantages, the decision to use abutments depends on various factors, including the condition of the teeth, the general health of the patient, and individual needs. Consultation with a specialist dentist is important to evaluate and choose the most suitable option.

Adverse effects of abutment

Abutment is mainly used in dental prostheses and dental implants. Side effects associated with abutments usually depend on a variety of factors, including placement, oral hygiene, and materials used. Some possible side effects include:

1. Infection:

If oral hygiene is not observed, local infections may develop in the abutment area.

2. Gingivitis:

Lack of proper hygiene can lead to gum inflammation and problems such as periodontitis.

3. Pain and discomfort:

In the early stages, the patient may feel pain or discomfort in the abutment area.

4. Bone resorption:

In some cases, the bone surrounding the implant may erode, which can affect the health of the abutment.

5. Beauty problems:

If the color or shape of the abutment does not match with other teeth, cosmetic problems may arise.

6. Abutment movement:

In some cases, the abutment may become loose or displaced, requiring realignment. Before performing any dental procedure, it is necessary to consult with a dentist and fully examine individual conditions.

 

Is abutment installation painful?

The installation is usually not painful for the patient at all, but there may be some discomfort or mild pain, which is usually controlled with pain medication. This pain is usually present for a short time after the operation and gradually decreases

How long does it take to install the abutment?

The abutment installation time usually takes about 30 minutes to 1 hour, but this time may vary depending on the individual’s condition and the complexity of the operation.

How long does dental abutment last?

Dental abutments can usually last for 5 to 10 years or even longer, provided they are properly cared for and maintained with good oral hygiene.

Does dental abutment need special care?

To care for dental abutments, it is important to Oral hygiene Pay attention to yourself. Regular brushing, flossing, and regular visits to the dentist for periodic checkups can help maintain the health of the abutment. Also, if you see any abnormal symptoms, you should consult your dentist.

The difference between customized and prefabricated abutments

Design and manufacture:

Custom abutment: These types of abutments are specially designed and made for the needs of patients. These abutments are usually designed using CAD/CAM technology and allow for specific adjustments for angle, height, and dimensions.

Prefabricated abutment:

These abutments are mass produced and are usually available in standard sizes and angles. These types of abutments are usually suitable for many treatment cases, but may not cover the specific needs of a patient. *Custom abutments are usually more expensive because they require more precise design and fabrication. *Prefabricated abutments are usually less expensive due to mass production.

Production time:

Custom abutments require more preparation time due to the longer design and fabrication process. Prefabricated abutments are more readily available and can usually be used in less time.

The effect of abutment on the performance and durability of dental implants

 

The balance of the applied force:

Abutments help to correctly distribute the force applied to the implant. A proper abutment can prevent excessive pressure on a certain area and prevent fractures or other problems.

The ability to adapt to the patient’s anatomy:

A customized abutment can adapt well to the anatomical condition of the patient’s teeth, which can have a positive effect on the aesthetics and function of the artificial teeth.

Durability and longevity of the implant:

Choosing a suitable abutment can have a direct impact on the durability and life of the dental implant. High-quality and suitable abutments can prevent premature wear and subsequent problems

How to connect tooth abutment to Implant fixture

Select the connection type:

Abutments may be connected to the implant fixture in two ways: screw-based connection and adhesive connection. The type chosen depends on the clinical situation, the type of implant and the design of the abutment.

Use screws:

To connect the abutment to the fixture, a special screw that is compatible with the abutment is usually used. This screw is inserted directly into the fixture and firmly connects the abutment to it.

Final review and adjustment:

After attaching the abutment to the fixture, the dentist should check the condition of the abutment and ensure that it is positioned correctly and at the correct angle.
