The Article contains errors due to mistakes during Figure assembly. There is an overlap between Figure 4A “Titanium group” (a) and (b). The correct Figure 4 and accompanying legend appear below.

Immunohistochemical analysis of the expression of collagen I/III at 1, 2 and 3 weeks after implantation (DAB, ×200): (A) Expression of collagen I: (a) first week; (b) second week; (c) third week. Expression of collagen I in Mg–6Zn alloy group was significantly higher than the negative control group and the titanium alloy group postoperatively at 1 and 2 weeks. (B) Expression of collagen III: (a) first week; (b) second week; (c) third week. Expression of collagen III in Mg-6Zn alloy group was significantly higher than the titanium alloy group postoperatively at 1 and 2 weeks; negative expression of collagen III was also observed in titanium alloy group when compared with the negative control group postoperatively at 1 and 2 weeks. *Mg–6Zn alloy group versus negative control group (P < 0.05); #Mg–6Zn alloy group versus titanium alloy group (P < 0.05); ^titanium alloy group versus negative control group (P < 0.05).

In addition, there is a partial overlap between Figure 4B “Titanium group” (a) and Figure 5A “Titanium group” (a). The correct Figure 5 and accompanying legend appear below.

Immunohistochemical analysis of the expression of MMP-1/-13 at 1, 2 and 3 weeks after implantation (DAB, ×200): (A) Expression of MMP-1: (a) first week; (b) second week; (c) third week. Expression of MMP-1 in Mg-6Zn alloy group was significantly lower than the negative control group and the titanium alloy group postoperatively at 1 week; negative expression of MMP-1 was also observed in titanium alloy group when compared with the negative control group postoperatively at 1 week. (B) Expression of MMP-13: (a) first week; (b) second week; (c) third week. Expression of MMP-13 in Mg-6Zn alloy group was significantly lower than the negative control group postoperatively at 2 and 3 weeks. *Mg–6Zn alloy group versus negative control group (P < 0.05); #Mg–6Zn alloy group versus titanium alloy group (P < 0.05); ^titanium alloy group versus negative control group (P < 0.05).
