Abstract：
OBJECTIVE: The use of extracted teeth has been introduced as an option for bone grafting. However, the current method requires special machines and solutions, posing significant time and cost. The aim of this study was to evaluate the clinical performance of autogenous raw tooth particles (RTP), a grafting material made from a ground tooth using basic equipment, for alveolar ridge preservation.
METHODS: Twenty-three patients (12 study/11 control), having 14 and 13 sites were included for the study and control groups (commercially available xenograft), respectively. Radiographic measurements were taken at the baseline and the 4-month follow-up appointment. Furthermore, a questionnaire survey concerning the general preference of the type of graft to receive (if needed), before and after knowing the price, was distributed at the completion of the procedure for patients to answer.
RESULTS: Alveolar ridge width change was -1.03 ± 0.64 and -0.84 ± 0.35 for the study and the control groups, respectively. Regarding the height, the study group showed a buccal and lingual change of -0.66 ± 0.48 and -0.78 ± 0.81, respectively, while this was -0.78 ± 0.56 and -0.9 ± 0.41 for the xenograft group. There was no statistically significant difference between the groups. Patients preferred the raw tooth particles over other grafting materials (p = .01).
CONCLUSIONS: No core biopsies were taken to evaluate bone formation, which should be done in future studies. Within its limitations, the current study demonstrated that RTP graft could be an alternative graft for bone augmentation, offering a new cost-effective option for clinicians when available.

摘要：
目的：已将拔牙作为植骨的一种选择。然而,目前的方法需要特殊的机器和解决方案，构成显著的时间和成本。这项研究的目的是评估自体生牙颗粒（RTP）的临床表现，使用基本设备由地面牙齿制成的嫁接材料，用于牙槽骨的保存。
方法：23名患者（12名研究/11名对照），研究和对照组（市售异种移植物）包括14和13个部位，分别。在基线和4个月随访时进行射线照相测量。此外，关于接受的移植物类型的一般偏好的问卷调查（如果需要），在知道价格之前和之后，在手术完成时分发，供患者回答。
结果：研究组和对照组的肺泡脊宽度变化分别为-1.03±0.64和-0.84±0.35，分别。关于高度,研究组的颊部和舌部变化分别为-0.66±0.48和-0.78±0.81,而异种移植组为-0.78±0.56和-0.9±0.41。组间无统计学意义差异。与其他移植材料相比，患者更喜欢生齿颗粒（p=0.01）。
结论：没有进行核心活检来评估骨形成，这应该在未来的研究中进行。在其局限性内,目前的研究表明，RTP移植物可能是骨增强的替代移植物，为临床医生提供新的成本效益选择。
