the specific problems of each patient. This new cleaning technology is also effective when teeth are malaligned or very close together, and with surfaces that are not easily accessible and impossible to reach with a polishing cup and brush. We can also clean the tongue and palate. If the necks of the teeth are exposed, we can likewise deal with this without damaging the cementum or dentine. Whether a patient has gingivitis, periodontitis or peri- implantitis: AIRFLOW and PLUS powder allow us to work subgingivally down to a sulcus depth of up to 4 mm. Any- one who has ever caught rubber cups on orthodontic appliances and then administered a powder–water treat- ment jet will not want to do without this new method. Step 5: PERIOFLOW When it comes to removing subgingival biofilm, in 4 to 9 mm periodontal and peri-implant pockets, I recommend using PERIOFLOW. The PERIOFLOW nozzle has enabled the treatment of millions of periodontal pockets, and we have achieved excellent results in the case of peri-im- plantitis, for example. I recommend using it six to eight weeks after initial therapy. When doing so, it is important to ensure you do not work horizontally on the tooth and the pocket, but pocket by pocket, proceeding slowly and without pressure, ensuring an extremely gentle action. Working vertically is necessary here. Step 6: PIEZON If calculus is present, I opt for the latest technology: PIEZON. PIEZON NO PAIN is based on piezoceramic energy conversion of linear movements. Hand instru- ments are overshadowed here. PIEZON is not only highly precise, but also intelligent and minimally invasive. The PS tip is ideal for supra- and subgingival application, while the PI instrument can also be used on titanium or ceramic surfaces. The instrument is moved over the sur- face of the teeth without applying pressure (the PS instru- ment is held parallel to the tooth surface), to avoid any loss of tooth substance or changes to surface structures. Patients find this procedure very pleasant. Step 7: Control We must check that we have removed all biofilm and calculus. This is what patients expect of a professional in our field. I recommend performing this check with a fine probe and a pair of dental loupes. The chemical plaque check is followed by final examination and final diagno- sis by the dentist. Step 8: Recall Our aim is long-term stabilisation, preservation of tooth substance and avoidance of disease. This will only suc- ceed with regular recall. The patient should leave the dental surgery with a recall appointment, which must be scheduled at once based on the findings. This depends on numerous individual factors and risks, which include practical prophylaxis | the patient’s general anamnesis, diet, reconstructions, anatomical structures, cleaning habits and general state of oral hygiene. Conclusion We should ask ourselves every day: What is the ef- ficacy and benefit of each method? What is the effect of cleaning? What are the clinical parameters like? How much time can I take? What safety does the method of- fer me with hard- and soft-tissue and restoratives? What level of comfort can I offer patients? How do I guarantee the health of my patients? Hand instruments and conven- tional polishing do not provide satisfactory solutions, but GBT is already able to do so. GBT is a scientific concept for success at every den- tal surgery, offering intelligent guidance for every clini- cian. GBT is not only a safe and reliable procedure that smooths your path toward success, it also ensures even better treatment and dental prophylaxis results. I recom- mend that your entire team at the surgery try out GBT once—you will be delighted with it. prevention 1 2018 59
