“…These damage depths are much shallower than the 23-80 m damage depths using coarse burs [13]. This suggests that subsurface damage was significantly diminished by finishing using fine burs.…”

“…Coarse abrasive burs are used for bulk material removal processes, where the objective is to remove materials as efficiently as possible with little regard for surface quality [11,12]. Our previous research reported that subsurface damage depths in the feldspathic porcelain using coarse dental burs were in the range 23-80 m [13]. Such damage can cause stress concentration and reduction of mechanical strength in ceramic prostheses [6,7].…”

“…The damage created with coarse burs [grit size of 106-125 µm, approximately equivalent to that of Blue, Komet, Stuttgart, Germany (Kim et al, 2010a)] in glass ceramic (Vita Mk II, Vita) is extensive, propagating as deep as 114 µm beneath the surface at cutting speeds and depths similar to those used clinically (Song et al, 2008a,b;Song and Yin, 2009). Furthermore, subsurface damage increases linearly with cutting speed (the speed at which the bur moves across the surface at constant rpm) and depth of cut (Song and Yin, 2009).…”

Performance of Dental Ceramics: Challenges for Improvements

The clinical success of modern dental ceramics depends on an array of factors, ranging from initial physical properties of the material itself, to the fabrication and clinical procedures that inevitably damage these brittle materials, and the oral environment. Understanding the influence of these factors on clinical performance has engaged the dental, ceramics, and engineering communities alike. The objective of this review is to first summarize clinical, experimental, and analytic results reported in the recent literature. Additionally, it seeks to address how this new information adds insight into predictive test procedures and reveals challenges for future improvements.

“…Abrasive grinding using diamond burs in a dental air turbine is one method available for making such adjustments; however, the effects of this type of adjustment on all‐ceramic restorations are not yet fully understood. Previous researchers have demonstrated that surface and subsurface damage can arise from diamond bur machining of ceramic under simulated dental operatory conditions 1–4 . To date, most of this damage has been characterized in terms of the mode of machining damage, specifically the brittle and ductile modes of material removal 5 …”

“…Previous researchers have demonstrated that surface and subsurface damage can arise from diamond bur machining of ceramic under simulated dental operatory conditions. [1][2][3][4] To date, most of this damage has been characterized in terms of the mode of machining damage, specifically the brittle and ductile modes of material removal. 5 Ceramics, with their low-thermal conductivity and inherent brittleness, are known to be susceptible to thermal shock damage.…”
