目的 在过去的20年里，腭部种植体已被用于消除头盔磨损和建立固定支抗。本研究的目的是建立一种简便的腭部种植体植入方法和操作规程。 材料和方法 这项研究包括8名男性和15名女性患者，他们每人都在腭部植入了一个4.5x8 mm的阶梯形螺纹钛种植体，用于正畸目的。制备了含有金属钻头外壳的手术模板。根据上颌骨在旁正中平面石膏铸型层面上的放射学追踪，控制钻架的角度。植入物使用非侵入性技术(切开、皮瓣和缝线消除)放置，并留在黏膜处，以方便手术过程和减少手术。选择旁正中区域是为了避免腭缝的结缔组织，因为它被认为是种植植物的合适宿主部位。 结果 经过3个月的愈合，所有的种植体都是骨性结合的，在整个正畸治疗过程中没有种植体丢失。 讨论 腭部植入物可以有效地用于支抗维护和获得空间。 结论 三维手术模板的使用消除了错误的植入物放置，减少了坐椅时间，并最大限度地减少了对组织的损伤，同时增强了骨整合。
PURPOSE Palatal implants have been used in the last 2 decades to eliminate headgear wear and to establish stationary anchorage. The aim of this investigation was to establish a method and easy protocol for palatal implant placement. MATERIALS AND METHODS The study comprised 8 male and 15 female patients each having a 4.5 x 8-mm stepped screw titanium implant placed in the palatal region for orthodontic purposes. A surgical template containing metal drill housing was prepared. Angulation of the drill housing was controlled according to the radiologic tracing of the maxilla transferred to a plaster cast section in the paramedian plane. Implants were placed using a noninvasive technique (incision, flap, and suture elimination) and left transmucosally to facilitate the surgical procedure and reduce operations. The paramedian region was selected so as to avoid connective tissues of the palatine suture and because it was considered to be a suitable host site for implant placement. RESULTS After 3 months of healing, all implants were osseointegrated and no implant was lost throughout the orthodontic treatment. DISCUSSION Palatal implants can be used effectively for anchorage maintenance and space-gaining procedures. CONCLUSION Usage of a 3-dimensional surgical template eliminated faulty implant placement, reduced chair time, and minimized trauma to the tissues while enhancing osseointegration.
