A variety of esthetic restorative materials are available for restoring primary incisors. Knowledge of the specific strengths, weakness, and properties of each material will enhance the clinician's ability to make the best choice of selection for each individual situation. Intracoronal restorations of primary teeth may utilize resin composites, glass ionomer cements, resin-modified ionomers, or polyacid-modified resins. Each has distinct advantages and disadvantages and the clinical conditions of placement may be a strong determining factor as to which material is utilized. Full coronal restoration of primary incisors may be indicated for a number of reasons. Crowns available for restoration of primary incisors include those that are directly bonded onto the tooth, which generally are a resin material, and those crowns that are luted onto the tooth and are some type of stainless steel crown. However, due to lack of supporting clinical data, none of the crowns can be said to be superior to the others under all circumstances. Though caries in the mandibular region is rare, restorative solutions for mandibular incisors are needed. Neither stainless steel crowns nor celluloid crown forms are made specifically for mandibular incisors. Many options exist to repair carious primary incisors, but there is insufficient controlled, clinical data to suggest that one type of restoration is superior to another. This does not discount the fact that dentists have been using many of these crowns for years with much success. Operator preferences, esthetic demands by parents, the child's behavior, and moisture and hemorrhage control are all variables which affect the decision and ultimate outcome of whatever restorative treatment is chosen.
有多种美学修复材料可用于修复乳切牙。了解每种材料的具体优点、缺点和特性,将提高临床医生针对每种具体情况做出最佳选择的能力。乳牙的冠内修复可使用树脂复合材料、玻璃离子水门汀、树脂改性离子水门汀或聚酸改性树脂。每种材料都有明显的优缺点,放置的临床情况可能是决定使用哪种材料的重要因素。乳切牙进行全冠修复可能有多种原因。可用于修复乳切牙的牙冠包括直接粘结在牙齿上的(通常是树脂材料)以及粘结在牙齿上的某种类型的不锈钢牙冠。然而,由于缺乏支持性临床数据,在所有情况下都不能说哪种牙冠优于其他牙冠。尽管下颌区域的龋齿很少见,但仍需要针对下颌乳切牙的修复解决方案。不锈钢牙冠和赛璐珞牙冠都不是专门为下颌乳切牙制作的。修复龋坏乳切牙有多种选择,但缺乏足够的对照临床数据表明一种修复类型优于另一种。这并不否定牙医多年来一直成功使用许多这类牙冠的事实。操作者的偏好、家长的美学要求、孩子的行为以及湿度和出血控制都是影响所选修复治疗的决策和最终结果的变量。
