Axial-wall inclination angle and vertical height interactions in molar full crown preparations John F. Bowley, et al. - Axial single-side inclination angles greater than 10° in 3- and 4-mm height-molars are detrimental to maximum surface area in full crown restorations. The 5-mm axial wall height with ?10° single wall has been shown to maximize the luting agent surface area between restoration and tooth structure [more...]
