The Langer Curettes were designed to take the shank designs of the Gracey Curettes and combine them with the universal blade, thus allowing utilization of the same instrument for both mesial and distal surfaces. Langer Curettes have the following characteristics:
In addition to these characteristics, the Langer Curettes have a slightly shorter and thicker terminal shank. Thus, this makes them a little less flexible and much more effective on larger, tenacious calculus deposits. Langer Curettes can be ordered in standard, After Five and Mini Five designs. Figures 26‑29 show the types of Langer Curettes that are available.
The suggested areas of use are as follows:
1/2 Langer – Mandibular Posterior (both mesial and distal) (Figure 30)
3/4 Langer – Maxillary Posterior (both mesial and distal) (Figure 31)
5/6 Langer – Anterior and Premolar teeth (Figure 32)
17/18 Langer – Posterior (Figure 33)
