User Report DENTAL ASIA SEPTEMBER / OCTOBER 2020 40 Bausch , known manufacturer of occlusion test materials, recently developed a new system combining traditional and digital registration of occlusal force and contacts. The OccluSense ® system contains a special kind of occlusion paper that depicts pressure conditions. The thin, flexible colour-coated electronic pressure sensor is inserted into a battery- operated handheld device, which then records the static and dynamic occlusal data of the patient and sends it to the OccluSense ® iPad-App through a local wireless network. Users can see the selective occlusal forces on the iPad via 3D column graphics. It also displays a 2D diagram of the pressure distribution percentage in a related single occlusal segment. Additionally, the colour coated sensor marks the occlusal contacts of the patient in red. CLINICAL APPLICATION In modern innovative dentistry, the dentist has to face different sets of problems. For instance, the range of materials used in prosthetics has changed. Removable dentures have soft plastic occlusal surfaces in contrast to fixed restorations commonly made of ceramics and extremely hard zirconium oxide. Additionally, dentists deal with different types of abutment and anchorages which pose different resilience. The abutment can either be a natural tooth or implant that can be directly affected by the overall periodontal and oral health status of the patient. When different materials and abutments are involved, the problem of checking the occlusion arises. The static contacts appear concealed even with the use of an occlusion foil containing more wax. This issue is especially common with highly compressed surfaces such as zirconium oxide restorations. Often, secondary contacts appearing in a striking colour may lead to misinterpretations. Additionally, the movement in the temporomandibular joint (TMJ) such as compression, distraction, and lateral excursion can also obscure the image. The innovative technology of OccluSense ® is able to show the type of masticatory force loaded on the single contact points. Users can read the pressure of each contact from the graphic display. OccluSense ® records occlusal contacts irrespective of the marking on prosthetic surfaces. Premature or missing contacts are detected precisely. Through optimisation display, clinicians can correct problematic occlusal conditions caused by dynamic occlusion and excessive latero-and medio- trusion forces. In fact, OccluSense ® can be used in manifold ways in everyday practice. For instance, it is also useful in the occlusal evaluation of new or old prosthetic restorations. Long-time denture wearers may have difficulty adjusting to a new denture. Mostly, extensive adjustment must be done for them to feel a correct function.
