Summary

The aim of this study is to review the long-term soft tissue stability and the long-term esthetic results of single crowns supported by tissue level implants placed in non-augmented healed sites. The hypothesis of the present study is that tissue level implants can achieve ideal esthetic outcomes in non-augmented healed sites.

Detailed description

Both successful implant-supported restorations and the peri-implant soft and hard tissues are vital determinants which may affect the short- and long-term aesthetic outcomes. For this reason, the pink aesthetic score (PES) was introduced for the evaluation of peri-implant soft tissues by Fürhauser in 2005 and modified by Belser as PES/WES in 2009. So far, a series of clinical studies have confirmed the suitability of PES/WES and PES index for the objective outcome assessment of the aesthetic dimension of anterior single-tooth implants. However, to our knowledge, studies with long term data of the aesthetic outcome evaluation in non-augmented healed sites of the anterior maxilla are still rare, for most of the papers published recently mainly focused on immediate implant placement after tooth extraction with only 1-5 years following up. In our previous study, we have evaluated the alterations of soft tissue around implant-supported single crowns in the anterior maxilla with original standard PES at the time of crown placement and 6 months post-loading .We have found that the aesthetic outcome of soft tissue around the single-tooth implant had improved significantly at follow-up compared with baseline according to PES assessment. However, the follow up time of the previous study was short (6-8 months), long time follow up is necessary to confirm the previous hypothesis and observations.

Conditions

• Poor Aesthetics of Existing Restoration

Interventions

Type	Name	Description
PROCEDURE	single crowns supported by implants	The implant placement procedures were planned based on clinical and radiographic evaluation. During the surgeries, the mid-crestal incision and intra-crevicular incision were made following local articaine infiltration anesthesia. No releasing incisions were made. After full-thickness flaps were elevated labially and lingually to expose the alveolar ridge, the implants were placed according to the standard surgical procedures defined by the manufacturer. After a healing time of 10-16 weeks, implant-level impressions were taken. The porcelain (Ivoclar-Vivadent AG, Schaan, Lichtenstein) fused to noble metal crowns were fabricated. Abutment screws were torqued to 15 Ncm. Crowns were cemented with HY-bond Glassionomer Cement
