To describe a shift from injectable resin composite technique to composite resin computer-aided design and computer-aided manufacturing (CAD/CAM) veneers in addressing esthetic concerns associated with diastemas between anterior lower teeth in a clinical case.
Among several techniques proposed for direct resin composite restoration, the "Injectable resin composite technique" has gained popularity for its time-efficiency, reduced technique sensitivity, and diminished reliance on clinician skills. However, challenges such as staining and the need for frequent polishing follow-ups may prompt the consideration of more stable alternatives such as indirect veneer restorations. While ceramic veneers offer superior mechanical and optical properties, resin ceramic veneers, especially those milled from CAD/CAM resin ceramic blocks, offer advantages such as rapid, cost-effective production, simplified intra-oral repairs, less susceptibility to fracture, superior stress absorption, and requires minimal tooth preparation, making them an appealing option for many patients. Moreover, a fully-digital approach not only streamlines the process but also saves time and labor while ensuring the delivery of high-quality restorations to patients.
In addressing a patient's dissatisfaction with constant polishing of direct resin composite restorations, a shift to resin composite CAD/CAM veneers was implemented. Utilizing a fully-digital approach with CAD/CAM resin ceramic restorations successfully restored both esthetics and function.
While the injectable resin composite technique achieves immediate esthetic results, its low color stability necessitates frequent polishing sessions. The replacement of direct resin composite restorations with CAD/CAM resin composite veneers becomes a viable option for patients seeking more stable restorations that require fewer follow-ups. This transition addresses both esthetic concerns and the need for enduring solutions in restorative dentistry.
通过临床病例描述一种从注射型树脂复合技术向复合树脂计算机辅助设计和计算机辅助制造(CAD/CAM)贴面的转变,以解决前牙下牙间隙美观问题。
在直接树脂复合修复的几种技术中,“注射型树脂复合技术”因其省时、降低技术敏感性和减少对临床医生技能的依赖而广受欢迎。然而,诸如染色和需要频繁抛光随访等挑战可能会促使考虑更稳定的替代方案,如间接贴面修复。虽然陶瓷贴面具有优越的机械和光学性能,但树脂陶瓷贴面,特别是由 CAD/CAM 树脂陶瓷块铣削而成的贴面,具有快速、经济高效的生产、简化的口腔内修复、较少的易碎性、更好的应力吸收等优点,并且需要最小的牙齿预备,因此对许多患者来说是一个有吸引力的选择。此外,全数字化方法不仅简化了流程,还节省了时间和劳动力,同时确保向患者提供高质量的修复体。
在解决患者对直接树脂复合修复体频繁抛光的不满时,采用了树脂复合 CAD/CAM 贴面的方法。使用 CAD/CAM 树脂陶瓷修复体的全数字化方法成功地恢复了美观和功能。
虽然注射型树脂复合技术可立即获得美观效果,但它的颜色稳定性较低,需要频繁进行抛光处理。用 CAD/CAM 树脂复合贴面代替直接树脂复合修复体成为那些寻求更稳定、需要更少随访的修复体的患者的可行选择。这种转变既解决了美观问题,也满足了修复牙科中持久解决方案的需求。
