Abstract
Purpose The aim of this study was to assess the esthetic outcome of immediate placed and/or immediate restored dental implants in an extraction socket in the anterior maxilla. Besides the focus of this study is on patient satisfaction. It was hypothesized that immediate placement and restoration is not inferior to conventional placement and/or restoration. Materials and Methods Eighty-two patients were randomly assigned to four different treatment groups. The groups differ from immediate/conventional placement to immediate/conventional restoration of implants. All implants were installed in extraction sockets with bony defects ranging from </> 5mm. The patients were included when the unrestorable tooth was a tooth out of the upper esthetic area. The patients were able to give an informed consent. The esthetic outcome was objectively rated using the Pink Esthetic Score/White Esthetic Score (PES/WES) and the Implant Crown Aesthetic Index (ICAI) by a blinded researcher who had not been involved in the treatment. The subjective score was rated with the Visual Analog Scale (VAS). Results Complete objective data was extracted from 73 patients. After one year an acceptable clinical PES/WES outcome was measured for 94% patients of group one, 94% of group two, 90% and 91% of group three and four. The total esthetic outcome was mainly influenced by the appearance of the implant crown (WES) and to a lesser extent by the peri-implant mucosa (PES). A significant difference in esthetic outcome was measured over time for every group. No significant difference was measured between the groups. Significant correlation was measured between both indices PES/WES and ICAI. Subjective outcome measures demonstrated a positive difference over time for one group. Conclusion Within the limitations of this study (sample size, follow-up duration), the results suggest that immediate placement of a restoration in a extraction socket with a bony defect of >/<5mm was not less favourable than conventional loading. This is in favour of the direct treatment way. Subjective results show really satisfied outcomes after one year.
