17. Journal of Clinical and Experimental Dentistry 2019	De Andrade.GS et al [21].	Maxillary central incisors	CAD-CAM post and core nanoceramic, composite resin, hybrid ceramic, lithium disilicate, titanium, Y-TZP material (Yttria Stabilized Zirconia)	Similar to post	All ceramic	ANSYS (Analysis Systems) (ANSYS, Inc)	100N palatal, 45 degrees angle	Stress distribution on dentin was similar for all groups; these seem to be effective alternatives for conservative and aesthetic quality, crown core cement line stress is inversely proportional to the elastic modulus of the material. Post core cement line stress is directly related to the elastic modulus of the material.
18. Journal of Oral Biology and Craniofacial Research 2020	Nahar R et al [1].	Maxillary central incisors	FRC (Fiber-Reinforced Composite), CFR-PEEK (Carbon Fiber-Reinforced-Polyether Ether Ketone), GFR-PEEK(Glass Fiber Reinforced-Polyether Ether Ketone), PEKK (Polyether Ketone-Ketone)	Composite core	PFM and PEEK crown	ANSYS (Analysis Systems) (ANSYS, Inc)	100N, vertical force,45 degrees oblique force on the palatal surface	Both PFM (porcelain-fused metal crown) and PEEK with carbon fiber reinforced group observed that the post exhibited minimum von Mises stress, PEKK post maximum von Mises stress values.
19. JCD 2020	Tammineedi-s et al [22].	Maxillary central incisors	Dentin post, fiber post	Composite core	Porcelain crown	CATIA (computer-aided three-dimensional interactive application)(Dassault Systems)	100N, palatal surface, 45 degrees	Similar von Mises' stress value pattern of stress distribution; stress distribution is favorable in dentin posts.
20. Dental Research Journal 2021	Jafaris.et al [23].	Maxillary central incisors	NI-CR casting, glass fiber, titanium, zirconia post and core	Composite core	Zirconia monolithic crown	COMSOL Metaphysics software (Stockholm, Sweden)	100N, palatal, 135 degrees	Stress in the middle third of posts, glass fiber post stress distribution better than zirconia, cast post and core. Glass fiber post stress between the crown and cementoenamel junction if there is no ferrule more stress in the cervical region by glass fiber posts.
21. International Journal of Computerized Dentistry 2021	EIDR.et al [24].	Maxillary central incisors	CAD-CAM post made of FRC, high-density polymer, polymer-infiltrated ceramic network, metal alloy as control	Core same as post	Lithium disilicate crown	ANSYS (Analysis Systems) (ANSYS, Inc)		No statistical difference in all groups, no difference in unrestored fractures, and comparable resistance to cast metal post and core, so are acceptable alternatives.
22. Journal of the Indian Society of Pedodontics and Preventive Dentistry 2021	Patil DB.et al [25].	Maxillary central incisors	Carbon fiber, glass fiber, ever-stick	Composite	Porcelain crown	CATIA (computer-aided three-dimensional interactive application)(Dassault Systems)	200N, palatal surface, 45 degrees	Maximum stress was at the point of stress application, more stress was induced in this order: carbon fiber>glass fiber>ever-stick, more homogenous stress in ever-stick posts.
