目的:研究改良舌侧背板技术辅助Ⅳ类洞美学修复中对邻关系恢复的影响。方法:选择62例患者,随机分为两组。对照组:采用常规透明聚酯成形片;实验组:采用改良舌侧背板技术及解剖成形片,术后检查邻面接触情况,并结合X线片观察邻面成形效果。结果:实验组在邻面接触情况和邻面成形效果上满意度高,同对照组比较有显著性差异。结论:改良舌侧背板技术辅助Ⅳ类洞美学修复可以更好地恢复邻面形态、邻面接触区,建立良好的邻关系,其效果满意,可在临床中广泛应用。
Objective: To study the effect of ameliorated lingual back plate technique on the recovery of neighbors in the amending repair of type Ⅳ caves. Methods: Sixty-two patients were selected and randomly divided into two groups. The control group: the conventional transparent polyester formed tablets; experimental group: the use of modified lingual back plate technology and anatomic shaped tablets, postoperative examination of the adjacent surface contact, and combined with X-ray observation of the adjacent surface forming effect. Results: The satisfaction degree of the experimental group in the situation of the adjacent surface contact and the shape of the adjacent surface was high, and there was a significant difference compared with the control group. CONCLUSION: Ameliorative techniques of ameliorated lingual back plate can ameliorate the contact area and the adjacent contact area better, and the results are satisfactory. It can be widely used in clinical practice.
