ABSTRACT
Cervical margin relocation (CMR), also known
as deep margin elevation, is a minimally invasive
restorative technique used to reposition subgingival
margins to a supragingival level. Subgingival
margins, extending below the cemento-enamel
junction (CEJ) present significant biological
risk including violating the biological width,
potentially causing inflammation, attachment
loss and periodontal deterioration. CMR provides
a conservative alternative to conventional
management (surgical crown lengthening and
orthodontic extrusion) lengthening for managing
deep subgingival margins while maintaining
tissue preservation and restorative predictability,
improving accessibility and bonding reliability.
Despite its growing clinical adoption and
alignment with minimally invasive principles,
concerns persist regarding bonding predictability
on dentine or cementum substrates and the
long-term stability of the adhesive interface.
This case report illustrates the clinical protocol
of CMR performed prior to indirect ceramic
restoration on an endodontically treated posterior
tooth. A step-by-step description and literature-based discussion highlight its advantages,
material choices and limitations in relation to
biological width preservation and periodontal
health.
