摘要：

背景：研究发现采用舌侧凹槽加邻面流体树脂牙体预备方法制作玻璃纤维夹板，用其固定松动前牙可达到较为理想的临床固定修复效果。
目的：观察两种牙体预备方法制作玻璃纤维夹板固定松动前牙5年基牙与夹板脱黏率及固定修复效果。
方法：根据慢性牙周病诊断标准，并严格按照牙周夹板固定适应证选取经过牙周基础治疗后需纤维夹板固定的94例Ⅱ-Ⅲ度前牙松动患者，根据松动患牙间是否进行邻面固定分为2组，邻面未固定组采用舌侧凹槽牙体预备方法，邻面固定组采用舌侧凹槽加邻面流体树脂牙体预备方法进行纤维夹板固定。随后5年中定期临床复诊或电话随访，对固定修复效果进行评价。
结果与结论：5年中定期临床复诊或电话随访显示，邻面固定组76例基牙与夹板脱黏7例，邻面未固定组18例基牙与夹板脱黏12例，均已经进行再固定。与邻面未固定组相比，邻面固定组5年后两组患牙的探诊深度、附着丧失明显改善(P  < 0.05)，牙槽骨高度占根长的百分比增加(P < 0.05)，患者自觉舒适无异物感。结果证实，采用舌侧凹槽加邻面流体树脂牙体预备方法制作玻璃纤维夹板固定松动前牙的5年观察固定效果较好。

Abstract:

BACKGROUND: Studies have found that the glass fiber splint which is embedded into the groove on the lingual surface of the affected tooth plus fluid resin fixation between the gap of mobile teeth can achieve more satisfactory clinical effects on the stabilization of loose front teeth.
OBJECTIVE: To observe the clinical effects of glass fiber splints prepared using two tooth preparation methods on splinting loose front teeth and their debonding rate through a 5-year follow-up visit.
METHODS: Ninety-four chronic periodontal disease patients, who had received periodontal treatment, were enrolled in this study for their loose front teeth of degree II-III. All the enrolled patients were good candidates for periodontal splinting strictly in accordance with the indications for periodontal splinting. According to whether the fluid resin was used to seal the gap between the mobile teeth, the 96 patients were divided into two groups: patients undergoing glass fiber splint + fluid resin between the mobile teeth served as experimental group, and those only undergoing glass fiber splint as control group. All the patients were followed by regular clinical referral or telephone follow-up for 5 year, to evaluate the fixed effects.
RESULTS AND CONCLUSION: During the 5 years of regular clinical referral or telephone follow-up, seven of the 76 cases and 12 of the 18 cases were found in the experimental and control groups, respectively, to have debonding between the abutment and the splint. Compared with the control group, the probing depth and attachment loss of affected teeth were improved significantly (P < 0.05), and the percentage of alveolar bone height accounting for the root length increased significantly in the experimental group (P < 0.05) after 5 years of follow-up. Patients in the experimental group felt comfortable without foreign body sensation. The results confirmed that the glass fiber splinting plus fluid resin fixation between the gap of mobile teeth was a better treatment for loose front teeth during the 5-year follow-up.
