o Movement-Masticationo Speecho Airwayo Sensibility
o Esthetical reconstruction
ADVANTAGES
o 3D PRINTED PATIENT SPECIFIC IMPLANTS ARE AT THIS MOMENT NECESSARY FOR OPTIMAL TREATMENT IN SOME PATIENTS
o CUSTOM AND PATIENT SPECIFIC IMPLANTS MANUFACTURED BY 3D PRINTING WILL BECOME STATE OF THE ART TREATMENT IN NEAR FUTURE FOR ALL PATIENTS
