Several methods have been proposed for preparing the tooth for porcelain laminate veneer but each of them still has some problems. This study was undertaken to examine the general characteristics in preparation to find further modification. The reduction-thickness, aspects of the prepared surface and easiness of manipulation were evaluated by ten operators for three preparation methods (IDA, KOD, LVS). At the cervical region, a small tapered diamond point could successfully give a desired reduction-thickness close to the published standard. The reduction, however, generally tended to be less than the values desired by the standard at the middle and incisal regions even with the specified instruments and technique for each method. It was found from the results that it was easy and safe to prepare by placing the guide grooves perpendicularly to the tooth axis rather than along it. Further improvements maybe necessary for the configuration of the guide grooves involving their number and site as well as for the grinding instruments and technique.
