This study evaluated the immediate provisionalization of mini-implants with friction-engaging abutments in the mandibular anterior region. A total of 43 mini-implants placed in 30 consecutive patients had a survival rate of 100% over a follow-up period of 1 to 4 years. The overall change in marginal bone level from definitive restoration delivery to 1 year for a single-tooth mini-implant replacement was 0.17 0.42 mm, demonstrating bone gain. The mean changes in marginal bone level on the mesial and distal aspects were 0.18 0.46 mm and 0.16 0.40 mm, respectively, also representing bone gain. The difference between the mesial and distal change in bone level was not statistically significant (P = .93). The peri-implant soft tissue remained relatively unchanged at 1 year posttreatment.
