摘要

目的:由于拔牙后不可避免的组织重塑,现行指南建议在颊骨较厚(>1 毫米)的患者中植入即刻种植体。本研究的目的是调查颊骨厚度对即刻种植体植入过程中骨吸收的影响,并对上述骨吸收的两种测量技术进行比较:本研究是一项前瞻性非随机对照临床试验。共有 30 颗种植体被分成颊骨薄和颊骨厚两个研究组。主要结果是通过锥形束扫描,对颊骨薄和颊骨厚患者术前、种植体植入后 2 个月和 18 个月的垂直骨变化进行放射学评估。次要结果包括颊骨板厚度的变化、边缘骨损失和粉色美学评分:由于每组均有一个早期失败案例,因此仅对 26 个种植体进行了统计分析。此外,厚种植体组中有 2 名患者退出了研究。锥形束计算机断层扫描测量显示,2 个月后,薄种植体组的垂直骨量损失为 1.09,厚种植体组为 0.85。薄骨组的颊骨板吸收为 0.39 毫米,厚骨组的颊骨板吸收为 0.52 毫米。薄骨组的颊骨板为 1.25 毫米,厚骨组的颊骨板为 1.88 毫米。PES没有显示出任何明显的差异,具有非常好的美学效果:在当前研究的限制条件下,两组患者种植后的颊骨板吸收量和随后获得的厚度都表明长期效果良好。事实证明,两种测量技术在测量颊骨板变化方面具有可比性和可靠性。https://classic.Clinicaltrials: gov/ct2/results?cond=&term=NCT04731545&cntry=EG&state=&city=&dist=。

Evaluation of buccal bone resorption in immediate implant placement in thin versus thick buccal bone plates: An 18-month follow-up prospective cohort study

Objectives

The current guidelines recommend that immediate implants be placed in patients with thick (>1 mm) buccal bone due to the inevitable tissue remodeling that follows tooth extraction. The aim of the current study was to investigate the effect of buccal bone thickness on bone resorption in immediate implant placement and compare two measuring techniques of the aforementioned resorption.

Materials

The present study was designed as a prospective nonrandomized, controlled clinical trial. A total of 30 implants were split between the two study arms, thin buccal bone and thick buccal bone. The primary outcome was to assess vertical bone changes radiographically by cone beam scans preoperatively, at 2 months and 18 months after implant placement in patients with thin and thick buccal plate. Secondary outcomes included the change in the thickness of the buccal bony plate, marginal bone loss, and pink esthetic score.

Results

Only 26 implants were statistically analyzed as one early failure was observed in each group. Furthermore, 2 patients of the thick group withdrew from the study. Cone beam computed tomography measurements revealed that at 2 months the vertical bone loss was 1.09 for the thin group and 0.85 for the thick group. The buccal bone plate resorption of the thin group was 0.39 mm while it was 0.52 mm for the thick group. The buccal bone plate was 1.25 mm in the thin group and 1.88 mm in the thick group. The PES did not show any significant difference with very good esthetic results.

Conclusion

Within the limitations of the current study, the amount of buccal bone plate resorption and the subsequent thickness obtained after implantation in both groups suggest successful long-term results. The two measuring techniques have proven to be comparable and reliable in the measurement of buccal bony plate changes.

期刊介绍: The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
