Soft Tissue Augmentation Techniques in Implants Placed and Provisionalized Immediately: A Systematic Review

Table 6

Survival rate of implant and survival rate of suitable aesthetic results. Total exposure time corresponds to the sum of exposure time of implants that survived the follow-up time, exposure time to the failure of implants lost during the observation time, and exposure time up to the end of follow-up time for the implants that did not complete the observation period due to any reason.
