To evaluate the rupture length of the sinus membrane after applying a defined 1.2 mm defect comparing 3 different techniques: Summers lift, balloon-assisted technique (BASL), and hydrodynamic ultrasonic cavitational sinus lift (HUCSL).
Thirty fresh sheep heads (60 maxillary sinuses) were investigated. The sinus membrane was ruptured using a 1.2 mm pilot drill. Then Summers lift, BASL, and HUCSL were each performed on 20 sinuses, creating a 5 mm vertical lift of the sinus membrane. The length of the ruptured sinus membrane was measured before and after the experiment. The results of the different sinus lift techniques were compared using t tests.
The t test showed that the Summers lift leads to a significantly higher rupture length (P = .05) than BASL. The comparison between Summers lift and HUCSL showed a significantly higher rupture length with the Summers lift (P < .005). The same significance (P < .005) was found when BASL was compared with HUCSL. Comparing the increasing rupture length of the sinus membrane during the experiment, the t test showed a significantly greater rupture using BASL or the Summers lift compared with HUCSL.
The HUCSL technique yielded the lowest increase of rupture length compared with BASL and Summers lift. The technique therefore shows the lowest risk of a growing rupture of the sinus membrane in case of an iatrogenic puncture during preparation of the transcrestal approach.
通过比较三种不同技术（Summers 提升术、球囊辅助技术（BASL）和流体动力超声空化窦底提升术（HUCSL）），评估在制造一个确定的 1.2 毫米缺损后窦膜的破裂长度。
对 30 个新鲜羊头（60 个上颌窦）进行研究。使用 1.2 毫米的导向钻使窦膜破裂。然后分别对 20 个窦进行 Summers 提升术、BASL 和 HUCSL，使窦膜垂直提升 5 毫米。在实验前后测量破裂窦膜的长度。使用 t 检验比较不同窦底提升技术的结果。
t 检验显示，Summers 提升术导致的破裂长度显著高于 BASL（P = 0.05）。Summers 提升术与 HUCSL 的比较显示，Summers 提升术的破裂长度显著更高（P < 0.005）。当 BASL 与 HUCSL 比较时也发现了相同的显著性（P < 0.005）。比较实验过程中窦膜破裂长度的增加，t 检验显示与 HUCSL 相比，使用 BASL 或 Summers 提升术时破裂显著更大。
与 BASL 和 Summers 提升术相比，HUCSL 技术导致的破裂长度增加最低。因此，在经牙槽嵴入路准备过程中发生医源性穿刺时，该技术显示窦膜破裂扩大的风险最低。
