A NOVEL TECHNIQUE OF MAXILLARY MOLAR CLASS I RESTORATION INCORPORATING RESIN-COMPOSITE UNDER DENTAL OPERATING MICROSCOPE

抄録

Amalgam has been used as the standard material for filling cavities in posterior teeth for over a century. However, there is growing concern over the use of amalgam restorations due to the possible release of mercury into the body. Therefore, clinicians are increasingly choosing resin composites for esthetic restorations as an alternative to amalgam. However, it remains difficult to reconstruct the individual tooth shape and achieve functional and individual occlusion while working in the oral cavity. In addition, both the accuracy of the reconstructed tooth shape and the risk of secondary caries are known to be significantly affected by the skill of the clinician. Therefore, we have devised a novel technique to achieve the treatment goal of reconstructing the individual tooth shape and improve outcomes. All the procedures involved in this technique are performed using a microscope. Dental microscopy greatly improves both anatomical precision and hermetic sealing; consequently, it may help maintain the long-term stability of treated teeth.
