[The reasons why 13 MK1 attachment were re-fabricated and some methods for improvement].
OBJECTIVE
To investigate the reasons why 13 MK1 attachment were re-fabricated and to suggest some improvement methods.


METHODS
Mechanics and denture production technology were reviewed in 13 cases with MK1 attachment denture to determine the causes of failure.


RESULTS
In some cases, MK1 attachments were poorly designed, while in other cases problems were found during denture design and production process due to limited experiences at the initial stage. MK1 attachments were re-done based on the specific cause and the outcome was good after 1-1.5 years of follow-up.


CONCLUSIONS
When using MK1 attachment, prosthodontists should be familiar with the characteristics and indications of MK1 attachment. Meanwhile, we should strengthen doctor-patient communication and follow up patients timely to improve the success rate of MK1 attached denture repair.
