Eight central incisors had a crown length of 8\u2009mm (T1) and the other half a length of 12\u2009mm (T2). All crowns were cemented on the titanium base using a resin cement. After cementation, the samples were placed in a thermocycler for 5000\u2009cycles. Fracture strength was measured using a universal test machine.
