Although significant advancements have been made in surgical techniques for reconstructing severely resorbed alveolar bone, achieving predictable regeneration remains a considerable challenge. Many conventional ridge augmentation methods require extended edentulous healing periods and multiple surgical interventions. This clinical study introduces a simplified approach to advanced ridge augmentation using a wide-head tent-pole screw (WHTPS), aimed at enhancing procedural efficiency and achieving predictable clinical outcomes.
Thirteen patients with severely vertically resorbed mandibular segments or completely edentulous alveolar ridges-each presenting with a minimum vertical bone defect of 5 mm-were included in this study. A single WHTPS was placed at the most severe bone defect site, followed by bone grafting and coverage with a resorbable membrane. Postoperative panoramic radiographs were taken immediately after surgery and again on the day of WHTPS removal, following a healing period of 3 to 6 months. An additional follow-up radiograph was obtained after final prosthesis placement, with an average follow-up period of 5.5 months, to assess changes in the augmented bone. Patients were monitored clinically for a period ranging from 8 to 20 months (mean: 14.9 months).
The average vertical bone gain immediately after surgery was 8.86 mm (SD ± 2.59 mm), while an average bone resorption of 1.49 mm (17.79%) was observed during the follow-up period.
A single WHTPS effectively stabilized the graft material in cases of severe alveolar bone loss, thereby preventing its resorption and displacement. Further clinical studies are necessary to validate its long-term effectiveness.
尽管在严重吸收的牙槽骨重建手术技术方面取得了重大进展，但实现可预测的再生仍然是一项重大挑战。许多传统的牙槽嵴增高方法需要较长的无牙愈合期和多次手术干预。本临床研究引入了一种使用宽头帐篷杆螺钉（WHTPS）进行高级牙槽嵴增高的简化方法，旨在提高手术效率并实现可预测的临床结果。
本研究纳入了13例下颌骨严重垂直吸收节段或完全无牙牙槽嵴的患者，每位患者的垂直骨缺损至少为5mm。在最严重的骨缺损部位放置一枚WHTPS，然后进行骨移植并用可吸收膜覆盖。术后立即拍摄全景X线片，在3至6个月的愈合期后，在取出WHTPS当天再次拍摄。在最终义齿植入后获得额外的随访X线片，平均随访期为5.5个月，以评估增高骨的变化。对患者进行了8至20个月（平均：14.9个月）的临床监测。
术后立即的平均垂直骨增量为8.86mm（标准差±2.59mm），而在随访期间观察到平均骨吸收为1.49mm（17.79%）。
在严重牙槽骨丧失的病例中，单枚WHTPS有效地稳定了移植材料，从而防止其吸收和移位。需要进一步的临床研究来验证其长期有效性。
