Altering internal surface of putty impression material for better recording of tooth preparation margins
This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...
متن کاملTooth surface loss: Tooth surface loss: an overview
Pathological, non-carious loss of tooth tissue is an increasing problem to the dental profession, with young individuals especially at risk. This paper provides an overview of the problem with an emphasis on the possible causes, particularly those factors which may account for the increased incidence. The clinical appearance produced by the various aetiological factors is discussed and recommen...

متن کاملNoise in biopotential recording using surface electrodes
Electric events inside the human body cause potential differences on the skin. Surface electrodes can be used to measure these voltages. A surface electrode is in fact an electrochemical transducer. It converts the potential differences due to ion flows inside the human body into a measurable voltage. The measurement of bioelectric events is exposed to various sources of noise. The reactions th...
متن کاملRecording hand-surface usage in grasp demonstrations
Humans are expert graspers having mastered the use of their hands to grasp objects in different ways and for different purposes. Grasp data on how humans use their hands therefore provides an excellent resource to derive insights from human grasp behaviour which can be transferred to robotic hands. The important question is: what to record? We may record the demonstrated shape or configuration ...
