5 years of One-time therapy

Background

The progress in the new materials, and the study of the details of the technique, helped to develop protocols that today are known as precise and stable over time. With special focus interest in aesthetic areas, where the requirements of patients are very high and the need to refine with the final details of the case make it necessary to have the full range of solutions that guarantee long-term stability, high rate of survival and great stability of the soft peri-implant tissues.

Aim/Hypothesis

The objective of this article is to present the follow-up and re-evaluation of patients treated with immediate restorations using One abutment therapy, in a 5-year follow-up period.

Material and Methods

The realization of this study was carried out by a valuation of a working protocol of implant placement with immediate loading using ceramic reinforced PEEK (Elegance, Bredent, Senden, Germany) plus immediate loading. 48 Bredent implants blue SKY (Bredent Medical Group, Germany) were placed at healing bone. 32 SKY elegance abutments were placed as test group and 16 titanium abutment as control group. Analysis performed- Follow-up time- all measurements were done after 5 years of implant placement and compared with baseline time. Radiological analysis- Distances between platform to first bone contact were recorded. ISQ stability analysis- Stability measurements were made at day 0 + 65 ISQ were taken as minimum value needed. Mucogingival analysis and clinical findings- Bleeding index, insertion losses of periimplant mucosa or height loss were recorded. Values recorded as mean Sd and Median. Non-parametric Friedman test was applied to do the comparison between samples values.

Results

After analyzing and comparing the results, it was found that there are no significant differences between the measurements made for the period of origin (5 months) and the 5-year follow-up. In this way, the radiological analysis showed similar values recorded in mm 1.17 ± 0.87 for 5 months versus 1.21 ± 0.63 after 5 years. In relation to bleeding on probing, likewise, there were no significant differences between the periods analyzed. (P = 0.14)Finally, in the depth of insertion, the found values were similar after 5 years of follow-up. (4.11 ± 1.02 versus 3.96 ± 1.36).

Conclusion and Clinical Implications

With the limitations of this clinical study, it can be concluded that the technique of immediate loading on Elegance pillars was predictable and stable over time from an aesthetic and clinical point of view. The type of material used, together with One-Time-Therapy concept, allowed obtaining optimal clinical and aesthetic values.
