ObjectiveThe 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.Materials and MethodsTwenty‐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.ResultsAlveolar 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).ConclusionNo 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.

使用自体生牙颗粒与异种移植物保留牙槽嵴后的影像学变化：一项前瞻性对照临床试验


目的使用拔牙已被引入作为骨移植的一种选择。然而，目前的方法需要特殊的机器和解决方案，这需要大量的时间和成本。本研究的目的是评估自体生牙颗粒 （RTP） 的临床性能，RTP 是一种使用基本设备由磨牙制成的嫁接材料，用于牙槽嵴保留。材料和方法研究组和对照组（市售异种移植物）分别包括 23 例患者 （12 例研究/11 例对照），分别有 14 个和 13 个部位。在基线和 4 个月随访预约时进行放射学测量。此外，在手术完成时分发了一份关于在知道价格之前和之后接受的移植物类型（如果需要）的一般偏好的问卷调查，供患者回答。结果研究组和对照组的牙槽嵴宽度变化分别为 -1.03 ± 0.64 和 -0.84 ± 0.35。关于身高，研究组显示颊侧和舌侧的变化分别为 -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。两组之间无统计学意义差异。与其他移植材料相比，患者更喜欢生牙颗粒 （p = .01）。结论未进行粗针活检评估骨形成，应在以后的研究中进行。在其局限性内，目前的研究表明 RTP 移植物可以成为骨增强的替代移植物，在可用的情况下为临床医生提供一种新的具有成本效益的选择。
