基质细胞衍生因子-1α联合富血小板纤维蛋白对即刻种植患者种植牙骨组织再生的效果
Effect of stromal cell-derived factor-1α combined with platelet-rich fibrin on bone tissue regeneration around immediate implants
目的 探讨基质细胞衍生因子-1α(SDF-1α)对富血小板纤维蛋白(PRF)联合骨粉种植患者的骨组织再生的影响。 方法 选取2023年5月—2024年3月马鞍山市人民医院收治的120例种植牙患者,随机分为观察组和对照组各60例。对照组使用PRF联合人工骨粉,观察组在此基础上加用SDF-1α。比较两组患者术后12个月的骨密度、骨厚度、牙槽骨唇舌向宽度、种植体稳定性(ISQ)、探诊深度(PD)、龈沟出血指数(SBI)、美容效果,以及种植牙成功率、完全愈合率和局部感染率等指标。 结果 观察组治疗前后骨密度、唇侧根尖骨厚度、唇侧根中骨厚度、唇侧根冠骨厚度、骨宽度的差值均大于对照组(P <0.05)。观察组治疗前后PD、SBI的下降程度均大于对照组(P <0.05)。观察组ISQ评分高于对照组(P <0.05)。两组术后12个月牙体色泽评分和面部情况评分比较,差异均无统计学意义(P >0.05);观察组牙体外形评分及整体美观度评分均高于对照组(P <0.05)。两组种植牙成功率、完全愈合率和局部感染率比较,差异均无统计学意义(P >0.05)。 结论 SDF-1α联合PRF对种植牙患者具有积极的骨再生效果,能够有效提高骨密度和骨厚度,改善牙槽骨结构,增强ISQ,并对牙周健康有积极影响。该治疗方案在促进种植牙修复效果、提高治疗成功率方面具有较大临床应用潜力。
Objective To investigate the effect of stromal cell-derived factor-1α (SDF-1α) combined with platelet-rich fibrin (PRF) on bone tissue regeneration around immediate implants. Methods The study enrolled 120 patients with dental implants who were treated at our hospital between May 2023 and March 2024. These patients were randomly assigned to the observation group (60 patients) and the control group (60 patients). The control group received PRF combined with artificial bone powder, while the observation group was additionally treated with SDF-1α. Bone mineral density, bone thickness, buccolingual alveolar width, Implant Stability Quotient (ISQ), probing depth (PD), sulcus bleeding index (SBI), aesthetic outcome, implant success rate, complete healing rate, and local infection rate were compared between the two groups at 12 months postoperatively. Results The differences in bone mineral density, labial alveolar bone thickness at the apical, middle-root, and cervical levels, and bone width before and after treatment in the observation group were greater than those in the control group (P < 0.05). The reductions in PD and SBI after treatment were also greater in the observation group compared to the control group (P < 0.05). The ISQ of the observation group was higher than that of the control group (P < 0.05). At 12 months postoperatively, there were no statistically significant differences between the two groups in tooth color and facial appearance scores (P > 0.05). However, the observation group had significantly higher scores for tooth morphology and overall aesthetic appearance (P < 0.05). No significant differences were observed between the control and observation groups in terms of implant success rate, complete healing rate, or incidence of local infection (P > 0.05). Conclusion SDF-1α combined with PRF has a positive effect on bone regeneration in patients with dental implant by effectively increasing bone mineral density and bone thickness, improving alveolar bone structure, enhancing implant stability, and promoting periodontal health. This treatment regimen demonstrates significant clinical potential in optimizing implant restoration outcomes and increasing treatment success rates.
