About Crown & Abutment
Most dental implant systems require the attachment of an abutment (retainer) to the implant. This is the “nub” on which the implant’s dental crown, bridge or denture is secured.
The titanium, threaded implant that is placed in the jaw bone. Many patients believe the implant is the entire process. This is a common misunderstanding and is what leads to the confusion about cost. Some offices only place the implant in bone (periodontists, oral surgeons and endodontists). So, when contacting those offices they will only be able to provide a patient with the surgical cost, not the abutment and implant crown.
An implant abutment is the intermediate piece that holds the implant crown to the implant. Nearly 100% of the time an abutment is necessary. They are made of titanium or ceramic. Only when a one-piece implant (implant and abutment together) is used can the abutment be avoided. In most instances this is ill advised as this technique dramatically limits the restorative options for the crown and future use of the implant if the patients losses additional teeth.
This is the only part of the process that the patient is interested in, from the start. The replacement for the missing tooth is the actual implant crown. It is the last piece of the implant process. It can be made of porcelain, porcelain fused to metal or all metal depending on the area of the mouth and the functional demands of the patient. People who grind or clench their teeth are at much higher risk for porcelain fracture. Therefore, in non-cosmetic areas of the mouth it may be recommended that the implant crown be all metal.
