Ceramic materials such as zirconia are being used more and more frequently in modern restorative dentistry. However, removing zirconia restorations with conventional contra-angle handpieces is a challenging and lengthy procedure. Added to this is the high wear on the burs, especially with monolithic material. In some cases, the bur has to be changed at one-minute intervals. To address this problem, W&H has developed a new product line specifically tailored for these applications.

In the medical history, the 55 year-old patient states that he has no systemic disease and is not taking any medication. The patient’s lifestyle is similarly unremarkable. The patient has a few tooth restorations and two implants (2nd and 4th quadrants). On the basis of current findings, gingivitis is identified in an otherwise stable periodontal condition on the reduced periodontium (stage III, grade A).

Osseodensification is a non-subtractive drilling technique that preserves and compacts bone. This procedure attempts to increase bone density, insertion torque and implant stability. The technique is suitable for horizontal augmentation in narrow alveolar ridges, as well as for vertical height gain via crestal sinus lift.

A 52-year-old patient presents at a prevention session. The patient has no systemic disease and is not taking any medication. He has had various dental treatments and also has two active carious lesions. In addition, the patient has four implants (2nd, 3rd and 4th quadrants). He is revealed to have early periodontal disease (stage IV, grade B). His periodontal condition is stable; a probe depth of 5 mm is only evident at the implant in region 36. Gingivitis is also identified.
