Selected cases have been presented using different techniques to alter crestal levels. Self Regeneration or Autogenous bone grafts have been most successful in cases of three-wall and two-wall infrabony lesions. When a hemiseptal lesion occurs on the mesial of a tooth an uprighting procedure can be accomplished. When there is an adjacent tooth a forced eruption technique using orthodontic forces can be used. A surgical elevation technique has been presented which also has shown positive changes in bony topography.
已展示了一些采用不同技术改变嵴顶水平的选定病例。自体再生或自体骨移植在三壁和两壁骨下袋病变的病例中最为成功。当牙齿近中出现半侧牙槽骨病变时，可以完成直立操作。当有相邻牙齿时，可以使用正畸力的强制萌出技术。还介绍了一种手术提升技术，该技术也显示出骨形态的积极变化。
