Abstract

OBJECTIVES To compare the histomorphometric outcomes of biopsies collected from the antrostomy and from the alveolar crest of the maxillary sinus after a sinus-lift procedure. MATERIAL AND METHODS In 12 volunteers, sinus floor elevation was performed using collagenated corticocancellous porcine bone. Nine months after the surgery, 2 biopsies, 1 from the alveolar crest and 1 from the antrostomy, were collected for histological analysis. RESULTS Biopsies from 11 patients were available for histological analyses (n = 11). At the alveolar crest sites, the percentage of mineralized bone was 40.1 ± 14.1%, of bone marrow was 40.1 ± 18.0%, and of the xenograft was 14.7 ± 15.2%. Small amounts of soft tissue were found. At the antrostomy sites, the percentages of mineralized bone, bone marrow, and xenograft were 26.0 ± 10.8%, 23.4 ± 17.0%, and 28.2 ± 15.7%, respectively. Soft tissue was represented by 19.7 ± 19.4%. CONCLUSION Higher amounts of mineralized bone and bone marrow were found in the alveolar crest compared with the antrostomy.

窦底抬高和Anthromy愈合：一项人类组织形态计量学临床研究。

目的比较上颌窦窦窦造瘘术后和上颌窦牙槽嵴活检的组织形态计量学结果。材料和方法在12名志愿者中，使用胶原皮质松质猪骨进行窦底抬高。术后9个月，收集2例活检，1例来自牙槽嵴，1例取自胃窦造口术，用于组织学分析。结果11例患者的眼压可用于组织学分析（n=11）。在牙槽嵴部位，矿化骨的百分比为40.1±14.1%，骨髓的百分比为4.01±18.0%，异种移植物的百分比为14.7±15.2%。在窦造口术部位，矿化骨、骨髓和异种移植物的百分比分别为26.0±10.8%、23.4±17.0%和28.2±15.7%。软组织占19.7±19.4%。结论与胃窦造瘘术相比，牙槽嵴内矿化骨和骨髓含量较高。
