Outline of Final Research Achievements

With the purpose of qualitative assessment of the volume change of labial tissue over time after implant treatment applied with bone and soft tissue augmentation in maxillary anterior region, the following results are reached:
As for the volume change of labial hard and soft tissue of implant site over time, it is possible to perform excellent assessment with CBCT imaging in terms of reliability and validity.
In delayed placement cases with bone and soft tissue augmentation, the ratio of width of hard and soft tissue was about 1:1. The total tissue width was 2.8mm.In immediate placement cases, when the placement was performed with only bone augmentation, a resorption of labial tissue relative to the gap width between implant bodies and extraction sockets was observed. However, when the placement was performed with both bone and soft tissue augmentation, tissue resorption was compensated, and mucosal contours were maintained in a manner close to pre-op status.
