Single-tooth implants (implant crowns) can be used in people who are missing one or more teeth.
This is the most common type of implant treatment in New Zealand and usually funded by ACC due to trauma. If you have had trauma and lost your front tooth, you could be eligible for ACC support with whom Northland Prosthodontics works closely.
An implant is surgically placed in an opening that your dentist makes in the jawbone. After the implant integrates (attaches) to your bone, it acts as a new “root” for the crown that will replace your missing tooth. A crown (cap), which is made to look like a natural tooth, is attached to the implant and fills the space left in the mouth by the missing tooth.
For this procedure to work, there must be enough bone in the jaw. The bone has to be strong enough to hold and support the implant. If there is not enough bone, it may need to be added with a procedure called bone augmentation or bone grafting. In addition, natural teeth and supporting tissues near where the implant will be placed must be in good health.
How Do They Work?
An implant crown consists of several parts.
- The implant, which is made of titanium, is placed in the upper or lower jawbone.
- The abutment can be made of titanium, gold or porcelain. It is attached to the implant with a screw. This part connects the implant to the crown. It is shaped like a natural tooth that has been cut down to receive a crown.
- The restoration (the part that looks like a tooth) is a crown. It usually is made of porcelain fused to a metal alloy (PFM). It also can be all metal or all porcelain. The crown is screwed or cemented onto the abutment. If the crown is screwed to the abutment, the screw hole will be covered with restorative material such as tooth-coloured filling material (composite).
