摘要:

背景:目前大量研究证实短种植体与常规种植体的成功率无明显差异,但对于超短种植体应用在上颌后牙骨量严重不足中的临床效果并不明确。

目的:短期观察超短种植体应用在上颌后牙区骨量严重不足中的临床效果。

方法:纳入18例上颌后牙骨量严重不足患者,其中男10例,女8例,年龄25-68岁,平均余留牙槽骨高度为3.19 mm,均进行超短种植体植入结合上颌窦内提升治疗。通过用锥形束CT观察种植体修复后12 个月的骨结合能力,以及种植体周围边缘骨水平变化的情况。

结果与结论:18例患者均完成12个月随访,植入的21颗种植体均获得良好骨结合,完成义齿修复,均未发生软组织炎症。随访修复后12个月,21枚种植体近、远中边缘骨高度变化分别为(-0.21±0.78),(-0.16±0.55) mm;种植体近、远中边缘骨高度与修复后即刻比较差异均无显著性意义(P > 0.05)。表明在上颌后牙骨量严重不足的情况中应用超短种植体可取得良好的骨结合,同时能够维持种植体边缘骨量稳定,但仍需长期临床观察。

Abstract:

BACKGROUND: Research on rough-surfaced implants has demonstrated similar survival rates for short and conventional-length implants. It is not clear whether ultrashort implant in limited alveolar bone of the posterior maxilla can achieve good clinical results.
OBJECTIVE: To evaluate the clinical effect of ultrashort implants in limited alveolar bone of the posterior maxilla.
METHODS: Eighteen patients with 21 ultrashort implants in limited alveolar bone of posterior maxilla (the mean residual alveolar height=3.19 mm) were included in the study, including 10 males and 8 females, aged 25-68 years. At 12 months after restoration, the patients were detected with cone-beam CT to evaluate the osseointegration and marginal bone level around the implant.
RESULTS AND CONCLUSION: All the 18 patients completed the 12-month follow-up, and the 21 pieces of implants had good osseointegration. No soft tissue inflammation was found. At 12 months after restoration, the marginal bone height in the mesial and distal was (-0.21±0.78) mm and (-0.16±0.55) mm, respectively. Implant marginal bone changes in the mesial and distal had no statistical difference (P > 0.05). Ultrashort implants in limited alveolar bone of the posterior maxilla can have good osseointegration, maintain the marginal bone mass around the implant, but still need long-term clinical observation.
