The meta-analysis was performed using RevMan 5.4 software from the Cochrane Collaboration, with &lt;i&gt;p&lt;/i&gt; ≤ 0.05.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;A total of 14 studies were included. Both thin and ultrathin crowns demonstrated durability under thermomechanical loading for 5 years during clinical simulation. The fatigue survival rates under stepwise loading presented conflicting findings, which may be attributed to variations in procedural methodologies or cementation protocols. The mechanical strength of thin and ultrathin crowns was sufficient to endure occlusal stresses exceeding 1100 N. However, the fracture resistance of thin and ultrathin crowns was found to be statistically significantly lower than that of thick ceramic crowns (&lt;i&gt;p&lt;/i&gt; = 0.01 and &lt;i&gt;p&lt;/i&gt; ≤ 0.001, respectively). Furthermore, all crowns cemented with conventional cement exhibited statistically significant weakness compared to those bonded with resin cement (&lt;i&gt;p&lt;/i&gt; ≤ 0.001). Lithium disilicate and nano lithium disilicate crowns revealed more stable optical properties than zirconia-reinforced lithium silicate, and all exhibited more staining with longer exposure time to colored drinks. Resin ceramic crowns revealed the highest microleakage rate compared with zirconia and composite crowns.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Laboratory evidence suggests that thin and ultrathin ceramic crowns exhibit favorable survival rates and fracture resistance.

After cleaning, the zirconia blocks in groups iv–viii were applied with MDP primer. The blocks in each group were cemented together with resin cement (G-Cem Linkforce). Subsequently, each bonded zirconia block was sectioned using a water-cooled diamond saw into microsticks (1 × 1 × 9 mm³).
