There is more literature surrounding the restoration of sub gingival margins. Reitemeier et al (2002) discovered that high accumulation of plague surrounding crowns with sub gingival margins and therefore this leads to a poor gingival health. In another literature review comprising of 64 …show more content…
The first rule is that a clinician should extend 0.5 to 0.7mm below the tissue in case the probing depth is 1.5mm or less. It is argues that when individuals to be tested have less than 1.5mm depth of sulcus, the clinician have a very minute recession risk. It is well known that the tissue does not recede into biologic attachment, and therefore placement of margin more than 0.5 to 0.7mm is not required to put away the margin in patients with shallow sulcus. What is even important to note is that even if the clinician was cut off almost all the tissue to bone, he/she well get another tissue growth to bring about the attachment and a minimum of 1mm sulcus. It falls then that in all such patients, the danger in sub-gingival margins pepping is proceeding too deep thereby harming the attachment, something which may lead into inflammation (Gemalmaz & Ergin, 2002). The rule here is that in such situations it is important to always extend 0.5 to 0.7mm below tissue, though not deeper than that so to prevent prepping too much into the
