Aesthetic restoration of anterior teeth with implant supported restorations is one of the most difficult procedures to execute. Bone resorption following anterior tooth extraction often compromises gingival tissue levels for the implant restoration. In the last 10 years the focus has shifted from osseointegration, to creation of an implant borne restoration which is in harmony with the surrounding hard and soft tissue. Complete reconstruction of tooth and gingival related aesthetics remains the primary objective and in some instances can be very difficult to achieve.
采用种植体支持修复体对前牙进行美学修复是最难实施的操作之一。前牙拔除后的骨吸收常常会影响种植修复时牙龈组织的水平。在过去十年中，关注点已从骨结合转移到创建与周围软硬组织相协调的种植体支持修复体。牙齿和牙龈相关美学的完全重建仍然是主要目标，在某些情况下很难实现。
