The objectives of the present study were to determine whether the application of low intensity pulsed ultrasound could affect the formation and maturation of bone and suture after rapid palatal expansion in dogs.In 6 adolescent male beagle dogs, a rapid palatal expansion appliance was placed in attached to the bilateral permanent canine and third premolars and the expansion continued for 3 weeks. The appliance in each dog was still placed for another 4 weeks as a retainer and remover thereafter. Two types of bone labeling materials (tetracycline and calcein) were subcutaneously injected during expansion and immediately before sacrifice. Eight weeks after the removal of the expansion appliance, the animals were sacrificed and the dissected palatal specimens were evaluated histologically and bone morphometrically. The following results were obtained.(1) The application of low intensity pulsed ultrasound tended to inhibit the relapse of inter canine width as well as inter premolar width after rapid palatal expansion in male adolescent dogs.The application of low intensity pulsed ultrasound activated the formation and maturation of newly expanded mid-palatal suture in male adolescent dogs.These results suggest that the application of low intensity pulsed ultrasound would be effective for retention after rapid palatal expansion in adolescent.

为探讨低强度脉冲超声对犬腭部快速扩弓后骨和缝的形成和成熟的影响，在6只青春期雄性比格犬的双侧恒尖牙和第三前磨牙上放置快速扩弓器，持续扩弓3周。在每只狗中的器具仍然放置另外4周作为保持器和移除器。在扩张期间和处死前即刻皮下注射两种类型的骨标记材料（四环素和钙黄绿素）。在取出扩张器后8周，处死动物，并对解剖的腭标本进行组织学和骨形态学评价。获得了以下结果。(1)低强度脉冲超声的应用有抑制雄性幼犬快速扩腭后犬齿间宽度和前磨牙间宽度复发的趋势，低强度脉冲超声的应用激活了新扩腭的中、后牙槽骨的形成和成熟。这些结果表明，低强度脉冲超声的应用将是有效的保留后，快速青少年腭部扩张。
