Comparison between various grafting techniques.

Method		Pros	Cons
Autograft	Cancellous	Biocompatibility Best for defects smaller than 6 cm Fastest healing	Poor availability Disorders at the site of collection
Allograft	Demineralized bone matrix graft	Higher availability Sterilization process	Lower acceptance Lower structural integrity Risk of rejection
	Cancellous	Availability Ease of application No prior harvesting required	Possibility of infection Low initial strength Risk of rejection
	Nonvascular cortical	High initial density of bone Mechanical properties	Weakening of graft after a time Risk of rejection
	Vascularized	Can be used in serious cases	Requires lifelong immunosuppressive drugs High risk of rejection
Synthetic	Ceramic	Rapid resorption and osteointegration Tailored shape and composition	Mediocre mechanical properties Material degradation
	3D printing using SLA	Precisely designed shapes High precision High speed Cheap materials	Lower biocompatibility Degradation over time Mediocre mechanical properties
	3D printing using FDM	Precisely designed shapes Wide range of materials Sterilization during the process High biocompatibility Dimensional stability Cheap materials	Lower print speed than SLA Lower resolution than SLA Non-uniform tensile strength
