It is apparent that tooth movement is enhanced by procedures that elevate the remodeling of alveolar bone, and of periodontal and gingival fibrous tissues. The periodontally accelerated osteogenic orthodontics (PAOO) also termed as Wilckodontics, involves full-thickness labial and lingual alveolar flaps accompanied with limited selective labial and lingual surgical scarring of cortical bone (corticotomy). Most of the authors suggest that the RAP is the major stimulus for alveolar bone remodeling, enabling the PAOO. However, we propose that detachment of the bulk of dentogingival and interdental fibers from coronal part of root surfaces by itself should suffice to stimulate alveolar bone resorption mainly on its PDL surfaces, leading to widening of the periodontal ligament space which largely attributes to accelerated osteogenic orthodontics. Moreover this limited fiberotomy also disrupts transiently the positional physical memory of dentition (PPMD), allowing accelerated tooth movement. During retention period, a new biological and physical connectivity is generated that could be termed as new positional memory of the dental arch.
很明显,通过提高牙槽骨、牙周和牙龈纤维组织重塑的程序可增强牙齿移动。牙周加速成骨正畸术(PAOO)也称为威尔克正畸术,涉及全厚唇侧和舌侧牙槽黏膜瓣,并伴有皮质骨(皮质切开术)有限的选择性唇侧和舌侧手术瘢痕形成。大多数作者认为快速骨改建(RAP)是牙槽骨重塑的主要刺激因素,促成了PAOO。然而,我们提出,从牙根表面的冠部大量分离牙齦和牙间纤维本身就足以刺激牙槽骨主要在其牙周膜表面吸收,导致牙周膜间隙增宽,这在很大程度上归因于加速成骨正畸术。此外,这种有限的纤维切断术还会暂时破坏牙列的位置物理记忆(PPMD),从而允许牙齿加速移动。在保持期,会产生一种新的生物和物理连接,可称为牙弓的新位置记忆。
