Abstract

Abstract:

Objective

To observe the clinical effect of the restoration of a single upper missing tooth with immediate implant placement and non-functional prosthesis in the aesthetic area.

Methods

Seven consecutive patients with un-savable single teeth in the aesthetic zone were included. Teeth were extracted and replaced with immediate implant and non-functional provisional crowns. Suitable permanent abutments were chosen and porcelain-fused-metal or allceramic restorations were made on the abutments after 6 months. Patients were followed up 1 year after crown insertion. The marginal bone level around the implant and Pink Esthetic Score （PES）value immediately after crown insertion and 1 year later were measured for comparison.

Results

The success rate of implant was 100%， mesial and distal peri-implant bone changes were （0.79 ±0.48）mm and （0.71 ± 0.46）mm respectively. The average PES value was （8.6 ± 1.3） and （11.1± 1.8）， respectively. Significant difference was found by Walcoxon analysis （P =0.027）.

Conclusions

For strictly selected cases， single-tooth immediate implant and immediate nonfunctional prosthetsis is an effective method. Good appearance can be achieved and the esthetics of peri-implant soft tissue can be improved over time.
