Table 1 Evaluation criteria of occlusal contact distribution in MIP using a 100-µm articulating paper

4 (Excellent)

Good occlusal contact distribution; occlusal contacts between supporting cusps and opposing fossae or ridges

3 (Good)

Individual occlusal contact points missing or are deviated, but the occlusal contacts on the main supporting cusp and crown are still functional

2 (Satisfactory)

Occlusal contacts present on other parts of the occlusal surface, but no occlusal contacts on the supporting cusps

1 (Unsatisfactory)

Distribution detrimental to crown stability or no occlusal contacts
