Bond Strengths:  The Importance of Hyperconjugation

Organic Letters, 2006
[Structure: see text] Gronert (J. Org. Chem. 2006, 71, 1209) has challenged the importance of hyperconjugation in determining C-H bond dissociation enthalpies (BDEs) in alkanes. Electron paramaganetic resonance spectra of H3CCH2*, (H3C)2CH*, and (H3C)3C* show significant positive spin on their beta-H3C groups' hydrogens. A 55%/45% partitioning of these

Orthodontic bonding to porcelain—Bond strength and refinishing

American Journal of Orthodontics and Dentofacial Orthopedics, 1988
Glazed porcelain surfaces are not amenable to resin penetration for orthodontic bonding. The aims of this study were to evaluate (1) the bond strengths of two orthodontic composite materials to treated porcelain surfaces, (2) the effect of thermocycling, and (3) the porcelain surfaces after refinishing.

Bond strength and durability of porcelain bonding systems

The Journal of Prosthetic Dentistry, 1996
Because the most effective bonding system for ceramic restorations has not been documented, this study examined bond strength and durability of bonding systems joined to a feldspathic porcelain. Disks of porcelain specimens were fired on refractory investment materials and were air-abraded with alumina.

Bond strengths of dentine bonding agents to dentine

British Dental Journal, 1992
This study assessed comparatively the tensile bond strengths to dentine of four resin dentine bonding agents. Flat surfaces were produced in the occlusal dentine of human third molars, finished with 600-grit paper and prepared for bonding to Silux Plus composite with Gluma, Prisma Universal Bond 2, Scotchbond 2 and Tenure.
