Suggestions for post insertion are as follows : 1 . the stress can be reduced by counterrotating the dowel one - fourth turn after resistance to installation has been detected . 2 . the channel should be cleaned thoroughly before post insertion . 3 . because accurate post fit is important to maximize both retention and support , the screw post should be used with the matched post / reamer syste ; and accurate contrangle drilling should be maintained 3 .由于根柱和根柱孔的精密吻合，对于固位及力量传递的支持有重要的影响，因此打桩时要精确做到根柱孔的乡钻制，对于偏斜的弯机要避免使用，而且要选用同号组合配对的钻针。
