目的比较聚合瓷嵌体与口内直接树脂修复临床疗效的差别。方法将符合纳入标准的86个患者随机分成两组。分别以聚合瓷嵌体、复合树脂充填的修复,随访2年,观察两种修复形式边缘密合,邻接恢复,牙周健康情况及术后牙体组织折裂率。结果聚合瓷嵌体冠组术后其边缘密合性、邻接恢复、牙周组织健康程度均明显优于树脂直接充填组(P<0.05)。结论聚合瓷嵌体冠能精确地恢复无髓牙的邻面外形,较复合树脂直接充填有助于患牙的牙周组织健康,降低无髓牙受力折裂的机率。
Objective To compare the clinical efficacy of polymeric inlays and oral direct resin repair. Methods Eighty-six patients meeting the inclusion criteria were randomly assigned to two groups. Respectively with the polymer porcelain inlay, composite resin filling repair, followed up for 2 years to observe the two forms of repair marginal adhesion, adjacent recovery, periodontal health and postoperative tooth tissue fracture rate. Results The marginal adhesion, adjoining recovery and periodontal tissue health were significantly better in the crown fusion group than those in the direct resin injection group (P <0.05). Conclusion Polycrystalline inlay crowns can restore the shape of the neoplasm of non-myelinated teeth accurately. Compared with the direct injection of composite resin, it can contribute to the periodontal health of the affected teeth and reduce the stress fracture of the non-myelinated teeth.
