各组正畸托槽在蚀刻15、30或60秒后附着在牙釉质上,在5、15分钟或24小时后剪切力剥离。蚀刻时间为15秒/剥离时间为5分钟的试样抗剪强度明显低于其他各组。有62%的试件在粘结后出现牙面损伤。因此,建议在粘接支架时常规进行15秒的蚀刻。如果要在5分钟内结扎支架,建议在30秒内进行蚀刻。60秒的蚀刻被认为太严重,不应该使用。
Groups of orthodontic brackets were attached to enamel after etching for 15, 30 or 60 seconds, they were debonded by shear forces after 5 or 15 minutes, or 24 hours. The 15 seconds etch/5 minutes debond time specimens had much lower shear strengths than other groups. Sixty-second specimens showed evidence of tooth surface damage after tie bonding. Fifteen seconds of etching is therefore recommended routinely for bonding brackets. If a bracket is to be ligated within 5 minutes of placement, 30 seconds etching is recommended. A 60-second etch is considered too severe and should not be used.
