Dental Abutment

A dental abutment is an integral part of a dental implant. Thought it remains hidden from sight once the dental crown is placed over it, it effectively transfers the force of biting and chewing from the dental crown to the deep, structural support of the implant fixture, which is embedded deep into the jawbone. It is this three-part structure of the dental implant that gives them their extreme strength and durability; this is why the wearers of dental implants are able to eat such a wide variety of foods even with prosthetic teeth.

Types of dental abutments

In the customary three-stage creation of a dental implant, a traditional abutment is most commonly used. In this process, the implant fixture – a small, screw-like piece typically made of either titanium, zirconium, or some other alloy– is first embedded into the jawbone to serve as the anchoring support for the implant. After the fixture is installed, the gums are stitched up over it and allowed to heal. Only after two to six months have passed and the fixture has melded completely with the jawbone, the gums are opened up once more so that the abutment can be attached to the fixture. At this time a temporary crown may be placed while the gums heal.

Healing abutments, on the other hand, can be placed at the same time that the implant fixture is placed. Rather than stitching up the gums and letting the soft tissues heal over the implant fixture, a healing abutment can be connected immediately so that the gums are allowed to heal around the structure that it provides. The primary benefit of a healing abutment is that it lessens the number of surgical procedures required. However, it also promotes gum health by lessening trauma via reduced surgical interventions.

When the implant fixture has become integrated into the jawbone and the implant crown is ready to be placed, the healing abutment can simply be switched with the permanent abutment, upon which the implant crown can then be fitted.

If the area in which the abutment is to be placed is in a highly visible area of the mouth, it may be preferable to opt for a custom-made abutment, which are made with the wearer’s own unique oral anatomy in mind. Custom-made abutments are more expensive than traditional abutments, but they can provide a custom look that some find to be worth the expense.

Choosing a dental abutment

Detailed planning is very important when it comes to dental implants, and you should discuss all of these options very carefully with your dentist when thinking them through. She or he will be able to provide you with advice that is tailored to your own unique situation and also to give more in-depth information about the benefits and drawbacks of any potential scenario. At this time, you’ll also need to consider the pros and cons of fixed or removable implant crowns, which might impact your decision-making surrounding abutment choices.
