M4M is polymerized with the TBB auto-polymerizing catalyst; therefore it shows low shrinkage at the marginal surface and possesses an advantage of minimizing gap formation [34].
Corresponding to the rather marginal, solvent-dependent differences in shrinkage, the spatial dimensions of BC specimen were largely preserved throughout loading and precipitation of PLA, CA and PMMA, and during scCO2 drying of the BC/PLA, BC/CA and BC/PMMA hybrid organogels, in particular for those variants with low polymer concentration in the loading baths.
Furthermore, the idea of averaging over models using different shrinkage weights, approximate the corresponding marginal probabilities by BIC for faster computation are aspects of BMA analysis that deserve more attention.
For comparable observation periods but with different micro-hybrid composites, most studies [ 11– 13] have reported similar deterioration of marginal integrity due to factors such as shrinkage stress, the effect of cavity geometry on C-factor [ 14, 15], butt-joint occlusal margin and self-etch adhesives.
Thus, by decreasing the bulk amount, of resin used, this technique can also reduce the detrimental effect of polymerization shrinkage, which may result in microleakage and marginal gap [ 30].
This step was based on a previously published work conducted by our group which included identifying confounders for specific medications using marginal odds ratios (ORs) and estimating the drug ADR associations using a least absolute shrinkage and selection operator (LASSO) type regularization [ 31].
The shrinkage of the material can cause post-operative sensitivity and/or debonding, and consequently, marginal staining, microleakage and secondary caries [14].
The marginal areas of CR might receive stress concentration, and subsequent micro-gap formation possibly occurred due to polymerization shrinkage during the photo-polymerization.
When shrinkage estimation procedures are used, prediction accuracy increases monotonically with marker density, but it does at diminishing marginal rates of response.
