Alveolar bone augmentation before implant placement is a safe and effective treatment option for the reconstruction of a deficient alveolar ridge. According to recent research, permanent teeth have been used as bone graft materials, with studies confirming their clinical and histological results. This study aimed to evaluate the efficacy of alveolar ridge augmentation with autogenous tooth roots and staged implant placement, and peri-implant tissue stability in augmented sites. A total of 20 augmentations with autogenous tooth roots on mandibular alveolar ridges in 15 patients were performed. After 6 months, the ridge width (RWa) and ridge width gain (RWg) were measured. Titanium dental implants were placed in grafted sites and loaded 10 weeks after placement. Clinical parameters (bleeding on probing-BOP; probing depth-PD; mucosal recession-MR; and clinical attachment level-CAL) were assessed 2 months (T1), 3 years (T2), and 5 years (T3) after implant loading. The mean RWa was 6.71 ± 0.74 mm, and the RWg was 3.15 ± 0.54 mm, respectively. No statistically significant differences were observed for clinical parameters (BOP, PD, MR, and CAL) among different time points ( > 0.05). Autogenous tooth roots represent a viable solution for alveolar ridge augmentation and implant placement, providing a stable environment for peri implant tissues.
种植体植入前的牙槽骨增量是重建牙槽嵴缺损的一种安全有效的治疗选择。根据最近的研究，恒牙已被用作骨移植材料，多项研究证实了其临床和组织学结果。本研究旨在评估自体牙根牙槽嵴增量及分期种植体植入的疗效，以及增量部位种植体周围组织的稳定性。对15例患者的下颌牙槽嵴进行了共20次自体牙根增量。6个月后，测量牙槽嵴宽度（RWa）和牙槽嵴宽度增加量（RWg）。在移植部位植入钛牙种植体，并在植入后10周进行加载。在种植体加载后2个月（T1）、3年（T2）和5年（T3）评估临床参数（探诊出血-BOP；探诊深度-PD；黏膜退缩-MR；以及临床附着水平-CAL）。平均RWa为6.71±0.74mm，RWg分别为3.15±0.54mm。不同时间点的临床参数（BOP、PD、MR和CAL）之间未观察到统计学显著差异（>0.05）。自体牙根是牙槽嵴增量和种植体植入的可行解决方案，为种植体周围组织提供了稳定的环境。
