Dense hydroxylapatite is a synthetic, biocompatible, immunologically inert material that can establish a chemical union with bone when placed in intimate contact in histologic studies. The following is a preliminary report of the use of preformed dense, non-resorbable hydroxylapatite blocks as a grafting material for use in advancement and vertical lengthening of the bony chin associated with orthognathic surgical procedures. In rare instances where an autogenous bone graft would be required for vertical lengthening without any advancement of bony pogonion, the need is obviated by utilization of the hydroxylapatite solid block.
致密羟基磷灰石是一种合成的、生物相容性好、免疫惰性的材料，在组织学研究中，当与骨紧密接触时，它能与骨形成化学结合。以下是一份初步报告，介绍了使用预制的致密、不可吸收的羟基磷灰石块作为移植材料，用于正颌外科手术中下颌骨的前移和垂直延长。在极少数情况下，需要自体骨移植来进行垂直延长而不使下颌骨前缘前移，使用羟基磷灰石固体块可避免这种需求。
