Abutment (dentistry)

Dental bridge abutments are made such that the path of insertion of the teeth involved is nearly parallel with each other.

Partial denture abutments[2] are unique in that they may incorporate elements such as rest seats, guide planes, and recontouring.

[3] These abutments can be made from a variety of materials, such as titanium, surgical stainless steel, gold and zirconia.

Ceramic abutments have to be used with care, since their compressive strength is nowhere near that of titanium, gold or other noble metals.

Microbial leakage and colonization between the implant and the abutments can result in inflammatory reactions and crestal bone loss.
