Introduction to each scaler:
Now, we will highlight key features of each Langer curette and those they share with Graceys. We would recommend the full set of Langer curettes, as each one allows ergonomic access with proper fulcrums to specific zones in the mouth. Use our comparison photos to get to know each one below:
Langer 1/2– This universal curette is modeled with similar shank design and lengths as the Gracey 11/12. It is recommended for mandibular posteriors, but its universal cutting edges allow it to be used anywhere with appropriate angulation and fulcrum. Clinicians may find it is best for straighter, upright fulcrums and around premolars, first molars, and second molars, as it does not have many complex shank bends and may not provide the best terminal posterior access.
Langer 3/4– This curette is made with similar shank design and lengths to the Gracey 13/14 curette. It is recommended for maxillary posteriors. However, it has multiple contra-angled shank bends, so it can also be useful and extended into any posterior areas which may require instrument extension or advanced fulcruming. In fact, some clinicians keep this particular curette in each prophy pack as well, for a well-rounded universal curette for posterior access at terminal molars.
Langer 5/6– This curette is designed with a similar shank to the Gracey 5/6 and is recommended for the anteriors and premolars. This one curette effectively replaces the Gracey 1/2, Gracey 3/4, and the Gracey 5/6.
Langer 17/18– A later addition to the original series, this curette is made shank bends similar to the Gracey 17/18. It is recommended for posteriors (both maxillary and mandibular). Clinicians may find it is helpful around the most difficult-to-access distal line angles at terminal molars, and even into furcations, as it has the most complex shank design and the most potential reach into difficult spaces (though it may require more advanced cross-arch or opposite arch fulcruming). We recommend it even for severe recession on the upper linguals which extends around to the distals, as these can be some of the trickiest areas to instrument.
Above we see a lineup of the Langers curettes beside their corresponding Gracey designs. Surely, implementing this unique and often-overlooked set of curettes will feel like a natural transition, as most clinicians are fully familiar with these shank designs. Give them a try, enjoy simpler setups, easier sharpening, and lower costs for full-mouth coverage!
