Essential Tips For Choosing Dental Implant Connectors

If you have one or several missing teeth, there is a high probability that the dentist will recommend dental implants. The implant acts as the new root upon which the artificial tooth is placed. However, the new teeth cannot be directly connected to the implant without connectors, commonly known as abutments. 

What Is a Dental Abutment?

Once the dentist has successfully placed the implants into the jawbone, you will be allowed some time for the jawbone and gums to heal. After you are completely healed, the dental professional will place metal connectors into the implant to act as firm holders of the artificial teeth. Abutments are made of different materials, including:

  •  Titanium
  •  Stainless steel
  •  Gold
  •  Polyether ether ketone
  •  Zirconia

Key Considerations When Choosing Dental Implant Connectors

Whenever you think about a connector, consider the implant abutment connection interface (IACI). The IACI is the connection site where the abutment connects to the implant and is a significant determinant of the success of a dental implant procedure. Choosing the right connector has various benefits, such as:

  •  Improving the implant's longevity and esthetics.
  •  Preventing biological issues, such as irreversible implant damage and peri-implant disease.

The three main factors to consider when choosing IACI features include:

  • Mechanics- The main mechanical feature to consider is IACI's anti-rotation design, as it allows you to remove and reattach the abutment as you wish. Also, you should take into account the materials, quality, and machining tolerance of the abutment.
  • Biological Considerations- A good IACI should provide a seal against microbes. Remember that ingress of bacteria into the implant could lead to implant loss or peri-implant disease. So, choose an abutment that firmly connects with the implant to provide an adequate seal against the ingress of bacteria.
  • Clinical Utility- When going for dental implant surgery, ask your dentist about On-1 abutment, whereby the implant and abutment are placed as a single procedure. This technique helps in limiting bone loss, improving esthetics, and maintaining peri-implant stability.

Types of Connectors to Choose

Implant connectors mainly take two types:

  • External Connectors-The connector extends outside the implant body. It is durable and compatible with a wide variety of implant systems. However, it offers inadequate microbial seals and less esthetic results. Also, there is a risk of a rotational misfit.
  • Internal connectors- It is placed inside the implant body. It perfectly matches the implant, providing an improved microbial seal and better esthetics. More importantly, it offers better joint strength. 


As you plan to go for dental implant surgery, it's advisable to have the right information about the entire process. Typically, a dental implant procedure involves three main things: implants, connectors, and artificial teeth. To learn more about dental implants, contact a dentist.
