Alveolar bone remodeling after tooth loss results in reduced ridge dimensions in horizontal and vertical planes. To prevent this, various authors have proposed different ridge preservation techniques. A collagen plug is a novel material that has shown promising results in preserving the alveolar bone. PRP has also yielded favorable outcomes in wound healing and promoted osteoinduction and osteoconduction Thirty patients of both sexes with an age range of 30-18 years requiring bilateral extraction of teeth with similar tooth root anatomy in the maxilla or mandible were included in the study. The extraction of teeth was carried out atraumatically. The patients' arches were randomly divided and labeled as the test or control sides. Bone width was measured on both sides. A collagen plug, with PRP, was placed, and the extraction socket was sutured on the test side. The control side was just sutured. A baseline RVG was taken to record the apico-coronal height. The patients were recalled after 10 days for suture removal and evaluation of wound healing. Parameters were re-evaluated at three and six months postoperatively. The data were subjected to t-test and one-way ANOVA. The height of the crestal bone on the grafted side was more when compared to the non-grafted side three and six months after tooth extractions, and the difference was statically significant (P<0.001). No statistically significant difference was seen in the width of the alveolar bone three and six months after tooth extraction (P>0.05). Collagen and PRP provided reasonable socket preservation as simple and inexpensive options as compared to other materials.
牙齿缺失后牙槽骨重塑会导致牙槽嵴在水平和垂直方向上尺寸减小。为防止这种情况，众多学者提出了不同的牙槽嵴保存技术。胶原塞是一种新型材料，在保存牙槽骨方面已显示出有前景的结果。富血小板血浆（PRP）在伤口愈合方面也产生了良好效果，并促进了骨诱导和骨传导。本研究纳入了30例年龄在18 - 30岁之间、需要在上颌或下颌双侧拔除牙根解剖结构相似牙齿的患者，男女不限。牙齿拔除过程中尽量减少创伤。将患者的牙弓随机分组并标记为试验侧或对照侧，测量两侧的骨宽度。在试验侧放置含有PRP的胶原塞，然后缝合拔牙窝，对照侧仅进行缝合。拍摄基线根尖片以记录根尖 - 冠方高度。10天后召回患者进行拆线及伤口愈合评估。术后3个月和6个月重新评估各项参数。数据采用t检验和单因素方差分析。拔牙后3个月和6个月，植骨侧的牙槽嵴顶骨高度高于未植骨侧，差异具有统计学意义（P<0.001）。拔牙后3个月和6个月，牙槽骨宽度未见统计学显著差异（P>0.05）。与其他材料相比，胶原和PRP作为简单且廉价的选择提供了合理的拔牙窝保存效果。
