Abstract:

BACKGROUND: Because of the good physical and chemical properties, the quartz fiber post is considered as a prefer alternative to metal posts.
OBJECTIVE: To evaluate clinical effect and safety of MACRO-LOCK quartz fiber post restoration for residual root and crown.
METHODS: The patients with large-area anterior defect were randomly divided into 2 groups: quartz fiber post group: following complete root canal therapy, MACRO-LOCK quartz fiber post, ULPDENT resin adhesive, PULPDENT dual cure resin core material were used to restore tooth post and core, and then all-ceramic crowns or metal ceramic crown was applied; control group: cast metal teeth crown restoration was performed. The patients were followed up for 6 months and 3 years for observation of restoration effects.
RESULTS AND CONCLUSION: During the 3-year follow-up, there was 1 case of post and core loss, 1of broken fiber post, and no root fracture in the quartz fiber post group. The successful rate of the quartz fiber post group was higher than that of the control group during the 3-year follow-up (P < 0.05). The findings indicate that MACRO-LOCK quartz fiber post has a good long-term effect and safety to restore residual roots and crowns.
