切牙

Methods Twenty-four extracted teeth block were bonded with Ni-Cr alloy and 24 resin block were bonded with Ni-Cr alloy by two kinds of adhesive material. Those were Gluma comfort bond and Single bond. Those bonding complexes were stored in normal saline solution for 72 hours.

用两种通用型粘结剂（G1uma comfort bond与Single bond）分别将24颗离体牙试块与Ni-Cr合金粘结，24个树脂试块与Ni-Cr合金粘结，生理盐水中储存72h后分别测量抗拉伸强度和抗剪切强度。
