No Support? An Easy Bite Technique

Occasionally there are situations where a severely worn upper dentition requires full coverage porcelain crowns, or where there is a lack of posterior support distal to the canines. After preparation, how is the bite with an appropriate vertical dimension of occlusion (VDO) determined? If the VDO is to be unchanged (ie, the teeth are not worn), and if the upper arch were to be treated, all the teeth to be crowned could be prepared with the exception of the upper central incisors. The bite can be taken using the unprepared upper centrals as the vertical stops. Then, the centrals can be prepared and picked up in the original bite, if needed.
