Abstract

Abstract:

BACKGROUND: Light-cured resin is a new kind of material with beautiful color, high strength, wide range of applications, easy-to-use and inexpensive features. Patients are willing to accept it because of less or no grinding of the teeth.
OBJECTIVE: To observe the effect of light-cured resin to fill the interdental space between maxillary anterior teeth.
METHODS: A total of 32 patients aged 21-52 years were enrolled, 107 teeth with 75 oversized maxillary spaces, including 15 males and 17 females. One space between bilateral central incisors was found in 14 cases; three spaces between bilateral central incisors, left lateral incisor, and left canine were found in three cases; three spaces between bilateral central incisors, right lateral incisor, and right canine were found in two cases; four spaces between left central incisor, left lateral incisor, left canine, right central incisor, and right lateral incisor were found in three cases; three spaces between bilateral central incisors and lateral incisors were found in six cases; four spaces between left central incisor, left lateral incisor, right central incisor, right lateral incisor, and right canine were found in four cases. All the oversized maxillary spaces were filled with light-cured resin. Then, crown morphology, adaptation, color, degree of wear and loosening were observed during follow-up.
RESULTS AND CONCLUSION: After 3-year follow-up, 17 of 32 cases were successful in tooth repair: the crown morphology and tooth adaptation were good, and there was no prosthesis loosening or detachment and discoloration. The tooth space was repaired basically in another nine cases: the crown morphology and tooth adaptation were not good enough, no prosthesis loosening or detachment was found, but there were some defects at the gingival margin and contact surface of teeth as well as mild discoloration. Tooth repair failed in the other six cases with worse crown morphology and adaptation, prosthesis loosening or detachment, and severe discoloration, which need to be repaired again.
