Introduction Abutments are part of the implant prosthetic system which isusedindentistrytoconnecttheimplantcrownstodental implant [1]. ey are broadly classified into two categories: stockabutmentandcustomorpatient-specificabutment[2]. Stockimplantabutmentswereeconomicalanduserfriendly and can be used for implants at both tissue and bone level. Poor hygiene, poor esthetics, and poor alignment with angled implants led to the emergence of custom abutments [3].Infact,newCAD/CAMsystemsregisteredaconstantly increasing use in dentistry. is technology allows a com- pletely digital workflow, from impression to final frame- work, and the materials used showed excellent mechanical properties [4] and good internal fit [5] which make it possible to create patient-specific abutments that are both strong and esthetic. Custom-made abutments can be fab- ricatedbythreetechniques:lostwaxtechnique,CAD/CAM, and3Dprinting.Also,therearedifferentmaterialsthatcan beusedtofabricatecustomabutments,goldalloy,titanium, zirconia, and base metal alloy. Each one of these materials has advantages and disadvantages. Metal abutments, which areversatileandrobust,canbeusedanywhereinthemouth, but esthetics is compromised when used in the anterior maxilla. Zirconia abutments, which are composed of ce- ramic, can be placed anywhere in the mouth, but are most advantageous,whenusedintheestheticzone[6].Besidesits excellent strength and esthetic characteristics, zirconia ex- hibits hygienic properties comparable to titanium. Zirconia abutments can be layered by pink porcelain directly, when necessary,toapproximatethecolorofthesurroundingsoft tissue.
