A comparative study between the immediate and early implant on the aesthetic influences of the peri-implant soft tissues in the aesthetic area / 口腔疾病防治

ABSTRACT

Objective@# The aim was to compare and document the aesthetic influences on peri-implant soft tissues between the immediate and early implant placement in the aesthetic area. @*Methods @#22 patients with single anterior teeth missing were included and divided into 2 group. Group A (12cases): Following the extraction of teeth, 12 Zimmer implants were immediately placed into sockets. Group B (10 cases): 4~8 weeks after the extraction, 10 Zimmer implants were early placed into the healing sockets. Zirconia crowns were applied on the implants 6 months later after implantation. The peri-implant soft tissues in both group were examined and evaluated by pink esthetic score (PES) 6~12 months later. Analysis of the data was performed by software SPSS 13.0. @*Results @#The mean PES was 9.27 (clinical acceptance) for all of the implants. No significant were found for any of the parameters between the treatment modalities regardness of total PES or single PES. However there were significant differences in the following aspects: the correlation between periodontal disease and papilla, the correlation between gingival biotype and mesial papilla, the correlation between gingival biotype and alveolar process deficiency, the correlation between Implant location and midfacial soft tissue level. @*Conclusion@#There are no significant differences between immediate placement and early placement on the aesthetic outcome of peri-implant soft tissues. The aesthetic outcome are related to patients oral health condition and clinicians skills.
