Ridge preservation following tooth extraction is essential for maintaining the alveolar bone structure and facilitating successful dental implant placement. Various techniques have been proposed for this purpose, but there remains a need for comparative analysis to determine their efficacy.
This clinical and radiographic study compared two different techniques for ridge preservation: Technique A and Technique B. Fifty patients requiring tooth extraction were randomly assigned to either Technique A or Technique B group. Clinical parameters including pain, swelling, and soft tissue healing were evaluated postoperatively. Radiographic assessments were conducted to measure the dimensional changes in the alveolar ridge at baseline and after 3 months using cone-beam computed tomography (CBCT).
In the Technique A group, postoperative pain scores averaged 2.3 (±0.5) on a visual analog scale (VAS), while in the Technique B group, the average pain score was 2.5 (±0.6). The swelling was minimal in both groups with no significant difference. Soft tissue healing was satisfactory in both groups. Radiographically, the mean vertical bone loss was 1.2 mm (±0.3) in the Technique A group and 0.9 mm (±0.4) in the Technique B group, with a statistically significant difference ( < 0.05).
Both Technique A and Technique B demonstrated favorable outcomes in terms of postoperative discomfort and soft tissue healing. However, Technique B showed superior preservation of vertical ridge dimensions compared to Technique A. Therefore, Technique B may be considered more effective for ridge preservation following tooth extraction.
拔牙后牙槽嵴保存对于维持牙槽骨结构和促进种植牙成功植入至关重要。为此已提出了多种技术，但仍需要进行比较分析以确定其疗效。
本临床和影像学研究比较了两种不同的牙槽嵴保存技术：技术A和技术B。50例需要拔牙的患者被随机分配到技术A组或技术B组。术后评估包括疼痛、肿胀和软组织愈合等临床参数。使用锥形束计算机断层扫描（CBCT）进行影像学评估，以测量基线时和3个月后牙槽嵴的尺寸变化。
在技术A组中，术后疼痛评分在视觉模拟量表（VAS）上平均为2.3（±0.5），而在技术B组中，平均疼痛评分为2.5（±0.6）。两组肿胀均最小，无显著差异。两组软组织愈合均令人满意。影像学上，技术A组平均垂直骨吸收为1.2 mm（±0.3），技术B组为0.9 mm（±0.4），差异有统计学意义（<0.05）。
技术A和技术B在术后不适和软组织愈合方面均显示出良好的效果。然而，与技术A相比，技术B在垂直牙槽嵴尺寸保存方面表现更优。因此，技术B可能被认为在拔牙后牙槽嵴保存方面更有效。
