Abstract

PURPOSE

The fluid-dynamic technique is characterized by the hydraulic detachment of the mucosa and simultaneous filling of the sub-Schneiderian space, with a graft material of paste-like consistency.

MATERIALS AND METHODS

Authors performed 13 future site developments, on as many patients (4 men; 9 women; age 49.46 ± 12.44 years), using a nanocrystalline hydroxyapatite dispersed in an aqueous matrix as graft material. In the second stage, performed at 5.96 ± 1.72 months, 13 implants were placed after harvesting bone biopsies from the regenerated sites. The above samples were subjected to histological and histomorphometric analysis. The histomorphometric results were then compared with the bone density, measured in Hounsfield units.

RESULTS

The average percentage of vital bone was of 29.08% ± 14.7%, whereas the bone marrow and graft material were 59.75% ± 11.19% and 11.16% ± 10.88%, respectively. The percentage of vital bone has a significant correlation with the bone density of the recipient site (P = 0.003117). In contrast, the bone marrow (P = 0.08692) and the graft (P = 0.0799) do not show a significant correlation with this parameter.

CONCLUSIONS

The results suggest the validity of the method in the regeneration of bone volume in the subantral region.

摘要

目的

流体动力学技术的特点是黏膜水分离，同时用膏状稠度的移植材料填充施耐德氏下间隙。

材料与方法

作者对13例患者（4名男性；9名女性；年龄49.46±12.44岁）进行了13次未来位点开发，使用分散在水性基质中的纳米晶羟基磷灰石作为移植材料。在第二阶段，于5.96±1.72个月时进行，从再生位点采集骨活检后植入13枚种植体。对上述样本进行组织学和组织形态计量学分析。然后将组织形态计量学结果与以亨氏单位测量的骨密度进行比较。
