METHODS: 32 subjects with the re- quirement of crown restoration treatment for the first molar were recruited into the study. The occlusion of the crown res- toration was adjusted by articulating paper during treatment , after treament the occlusal data were obtained by T - scan msystem to record the occlusion in the intercuspation. H 出e crown had premature contact or had no contact with an- tagonistic teeth , it was considered to be occlusal disharmony. Besides ,
