There are options for the type of crown to be fitted over the implant in your mouth. An abutment is fitted on the implant to hold the Crown in place. The abutment and the base of the crown may be metal which in some light may make the tooth look a little dull. Alternatively, the abutment can be made of white material and the crown can be made of solid porcelain (white tooth colour). This will give a more natural look to the tooth.
