The effectiveness of the following procedures in improving the seating of full cast crowns were compared: internal escape channels, die spacing, occlusal venting, and a combination of die spacing with an escape channel. All techniques were shown to be similar in effectiveness. Die spacing produced the least consistent results. An internal escape channel, occlusal venting, die spacing, or a combination of an escape channel and die spacing did not influence the retention of full cast crowns.
内部排溢通道、代型间隙、咬合排气以及代型间隙与排溢通道的联合使用。结果表明，所有技术的效果相似。代型间隙产生的结果最不稳定。内部排溢通道、咬合排气、代型间隙或排溢通道与代型间隙的联合使用均不影响全冠的固位。
