Paper ID PS1-4 : The case report of maxillofacial prosthesis using a magnetic attachment after maxillary sinus cancer treatment

Thank you for presenting the recovery cases. After using both, please let me know if you have any considerations on how to choose the best case for the O-ring attachment and the magnetic attachment.

Thank you for your question.
It is thought that OPA provides retention and some grasping force, while magnetic attachment provides retention and support.
As for #23, OPA would be more suitable considering the loose tolerance of the rubber.
As for #27, a magnetic attachment would be considered appropriate as more support should be preferred.
Each of OPAs or magnetic attachments has their own advantages and the choice of case needs to be made, but in this case, we believe we were able to maintain the use of both.
