What does a dental implant abutment do

Its main function is to obtain retention, anti-torsion and positioning capabilities. The abutment achieves retention, torsion resistance, and positioning capabilities through an inner abutment link or an outer abutment link structure.

In simple terms, it provides support for the crown above the implant, thereby playing a stable role (Note: If the implant itself contains a complete gingival part, that is, a one-stage implant, the abutment is not required)

The abutment is also divided into a pure titanium abutment and an all-ceramic abutment.

Pure Titanium Abutments - Titanium is a material that combines toughness, light weight, good biocompatibility and durability with high strength. It has a high success rate, also has very high wear resistance and corrosion resistance, and is also particularly biocompatible, so it is widely used in medicine.

All-ceramic abutment - The all-ceramic abutment has better optical properties, so the restoration of "all-ceramic abutment combined with all-ceramic crown" can achieve a more beautiful effect. However, the all-ceramic abutment also has disadvantages such as low strength and relatively brittleness.

Pure titanium abutments do not have an advantage in aesthetic restoration. When using pure titanium abutments, the gingival soft tissue needs to be more than 3 mm to ensure that the metal color is not detected; if the thickness of the gingival soft tissue is only 2 mm, an all-ceramic abutment is required.
