Hi everyone,
I tried in a full gold crown on a mandibular first molar last week but was unable to remove the crown for cementation and was advised by a tutor to leave it be. However it was recently pointed out to me that this may be a potential problem when I present this patient as my finals case
I am aware that having parallel sided walls aids in retention however as the
crown cannot be removed at all I presume that there is no other reason
other than I have created an undercut in my preparation? Or are there any other reasons?
Apart from the crown being dislodged from the tooth are there any other
long term complications associated with not cementing the crown? I was
informed that cements are bacteriostatic and caries may develop under the
crown but I don't see that this differs from the Hall technique in
paediatrics where a stainless steel crown is placed on top of a deciduous
carious tooth.
Should I be monitoring the crown with a 6 month radiograph to look for
caries developing at the margins? How much space between the crown and
tooth still remains despite our best efforts?
Would the preferred option have been to cut the crown off and construct
another crown for the patient?
Any advice, comments or recommendations for studies or research associated with this situation would be gratefully received.
Thank you in advance for any advice give
