: The current study aimed to compare the amount of interdental bone loss between early and immediate implant placements. : A total of 16 immediate implants and 16 early implants radiographs were included in the current research. The bone level was assessed at two different stages: at the extraction appointment (T1) and after three to six months of implant placement (T2). A line was drawn from the cemento-enamel junction connecting adjacent teeth to the interdental line connecting the interdental alveolar crest at both stages. The difference between measurements in the T1 and T2 stages is the bone loss measurement for the early implant group. For the immediate implant placement sites, the measurements were taken from the interdental bone crest to the implant platform level. : A Mann-Whitney U test was performed to evaluate the differences between both groups. The descriptive statistics of the T1 and T2 stages for both groups suggest that the bone loss in the T2 stage was generally higher than T1 stage. The immediate implant group showed higher bone loss compared to the early implant group. Moreover, there was significantly higher bone loss ( = 0.039) in the immediate implant group compared to the early implant group. : The results of this study indicate that immediate implant might have disadvantages over early implant in terms of bone loss after the extraction of maxillary and mandibular molar teeth.
: 本研究旨在比较早期种植和即刻种植之间的牙槽骨丧失量。 : 本研究共纳入 16 例即刻种植和 16 例早期种植的影像学资料。在两个不同阶段评估骨水平：拔牙时（T1）和种植后 3 至 6 个月（T2）。在两个阶段，从牙釉质-牙骨质交界线连接相邻牙齿的线到连接牙槽嵴顶的牙间线。T1 和 T2 阶段测量值之间的差异是早期种植组的骨丧失测量值。对于即刻种植部位，从牙间骨嵴到种植体平台水平进行测量。 : 采用 Mann-Whitney U 检验评估两组之间的差异。两组 T1 和 T2 阶段的描述性统计数据表明，T2 阶段的骨丢失通常高于 T1 阶段。即刻种植组的骨丢失量高于早期种植组。此外，即刻种植组的骨丢失量明显高于早期种植组（ = 0.039）。 : 本研究结果表明，在上颌和下颌磨牙拔牙后，即刻种植相对于早期种植可能在骨丢失方面存在劣势。
