【摘要】：目的:本研究通过采用Vertise Flow自粘接流动树脂(VF)和Filtek?Z350Flowable Restorative(ZF)流动树脂修复牙颈部楔状缺损,观察比较修复后3个月、6个月、12个月的临床效果,探讨Vertise Flow自粘接流动树脂修复牙颈部楔状缺损的临床效果。方法:以大连医科大学附属第一医院口腔科诊断为楔状缺损的36名患者的80例患牙为研究对象,随机分为两组,实验组:采用Vertise Flow自粘接流动树脂充填;对照组:采用Adper?Easy One自酸蚀粘接剂加Filtek?Z350 Flowable Restorative流动树脂充填。纳入的病例要求缺损局限为牙釉质或为牙本质浅层,无明显牙髓刺激症状和无自发痛史,患牙半年内未做过修复、未受过外伤、未进行牙周或正畸治疗。将所有楔状缺损牙齿的牙体预备均只做改良型预备:金刚砂车针将洞壁磨粗糙,在釉质洞缘预备小斜面。本次试验,所有对象均不做垫底。牙体预备后用水完全喷洗,并用空气干燥5秒钟。实验组比色,隔湿,选用Vertise Flow自粘接流动树脂提供的量配端头将Vertise Flow流动树脂挤到洞内,用所提供的笔刷以适度的压力给整个洞壁和斜面涂敷Vertise Flow达15~20秒钟,用小笔刷清理周围多余材料,光固化灯照射20秒;继续重复上述步骤,每次厚度不超过2毫米,直至缺损处被完全修复。用金刚砂车针磨除唇颊面多余复合树脂,橡胶杯蘸抛光膏将牙面精修与抛光;对照组比色,隔湿,涂布Adper?Easy One自酸蚀粘接剂20秒,轻吹干5秒,光固化10秒,随后将Filtek?Z350 Flowable Restorative流动树脂注射入楔状缺损内,轻轻加压,分层固化,每层不超过2毫米,光固化灯照射20秒,继续重复注射、固化步骤,每次厚度不超过2毫米,直至缺损处被完全修复,用金刚砂车针磨除唇颊面多余复合树脂,橡胶杯蘸抛光膏将牙面精修与抛光。修复效果依据改良的Ryge标准进行评分,在修复后3个月、6个月、12个月分别进行观察记录。结果:修复后3个月,实验组和对照组所有修复体均为“alpha”,两组间比较P0.05,差异无统计学意义;修复后6个月,实验组有一颗牙齿透明度下降,有一颗牙齿修复体表面有凹陷,有一颗牙齿表面有砂砾感,分别记为“bravo”,对照组有一颗牙齿修复体表面有凹陷,有两颗牙齿边缘有裂隙,分别记为“bravo”,两组间比较P0.05,差异无统计学意义;修复后12个月,实验组牙齿透明度下降增加至两颗牙齿,表面有砂砾感增加至两颗牙齿,分别记为“bravo”,对照组边缘有裂隙增加至三颗牙齿,分别记为“bravo”,两组间比较P0.05,差异无统计学意义。结论:1.Vertise Flow自粘接流动树脂与Filtek?Z350 Flowable Restorative流动树脂修复牙颈部楔状缺损后3个月、6个月、12个月临床效果无明显差别。2.Vertise Flow自粘接流动树脂临床采用一步法,降低了临床操作难度,省时方便,是临床上修复楔状缺损的较好选择。
[Abstract]:Objective: to study the clinical effects of Vertise Flow self-adhesive flow resin (VF) and Filtek?Z350Flowable Restorative-ZF resin in repairing wedge-shaped defect of tooth neck after 3 months, 6 months and 12 months after repair. To investigate the clinical effect of Vertise Flow self-adhesive flow resin in repairing wedge-shaped defect of tooth neck. Methods: 80 teeth of 36 patients diagnosed as wedge-shaped defect in Department of Stomatology, affiliated first Hospital of Dalian Medical University were randomly divided into two groups: the experimental group was filled with Vertise Flow self-adhesive flowing resin; The control group was filled with Adper?Easy One self-etching adhesive and Filtek?Z350 Flowable Restorative flowing resin. The defect was limited to enamel or superficial dentin. There were no obvious symptoms of pulp irritation and no history of spontaneous pain. The affected teeth had not been repaired within six months without trauma and had not been treated with periodontal or orthodontic treatment. The teeth of all wedge-shaped defects were prepared only by modified method: Emery needle grinded the wall rough and prepared small oblique surfaces at the edge of the enamel hole. This experiment, all the objects do not do bottom. After tooth preparation, spray completely with water and dry with air for 5 seconds. In the experimental group, colorimetric, wet-proof, Vertise Flow self-adhesive flow resin was used to squeeze the Vertise Flow flowing resin into the hole, and the whole wall and inclined surface of the hole was coated with Vertise Flow for 1520 seconds with the brush provided. Clean up the excess material with a small brush and light curing lamp for 20 seconds. Repeat the above steps until the defect is completely repaired, each time no more than 2 mm thick. The excess compound resin of lip and cheek was grinded with Emery wheel needle, the tooth surface was refined and polished with rubber cup dip polishing paste, the control group was colorimetric, moisturized, coated with Adper?Easy One self-etching adhesive for 20 seconds, lightly blown dry for 5 seconds, and cured by light for 10 seconds. Filtek?Z350 Flowable Restorative flow resin was then injected into wedge-shaped defect, gently pressurized, layered solidified, no more than 2 mm per layer, irradiation of light curing lamp for 20 seconds, repeated injection, solidification steps, no more than 2 mm in thickness each time, Until the defect is completely repaired, remove the excess resin from the lip and buccal surface with a Emery wheel needle, dip the rubber cup in the polishing paste to finish and polish the tooth surface. The effect of restoration was evaluated according to the improved Ryge criteria and observed at 3 months, 6 months and 12 months after restoration. Results: three months after the restoration, all the prostheses in the experimental group and the control group were "alpha", the difference between the two groups was not statistically significant (P0.05), and the transparency of one tooth in the experimental group decreased 6 months after the restoration. One tooth had a sunken surface, one had a feeling of sand and gravel on the surface of one tooth, and one in the control group had a dent on the surface of the restoration, and two teeth had a fissure on the edge of the tooth, each of which was recorded as "bravo." There was no significant difference between the two groups (P 0.05). After 12 months of repair, the transparency of the teeth in the experimental group decreased to two teeth, and the feeling of gravel on the surface increased to two teeth, which were recorded as "bravo", respectively. The margin of the control group increased to three teeth, which were recorded as "bravo". There was no significant difference between the two groups (P0.05). Conclusion: there is no significant difference in clinical effect between Vertise Flow self-adhesive flow resin and Filtek?Z350 Flowable Restorative mobile resin in the repair of wedge-shaped defect of tooth neck. 2. Vertise Flow self-adhesive flow resin is a one-step method, which reduces the difficulty of clinical operation. It is convenient to save time and is a good choice to repair wedge-shaped defect in clinic.
