A guide device is provided that can interact with a number of sleeves of a
tooth template. The guide device can include a handle part, a support
part, and a guide part. The handle part can include first and second
parts. The first part can be connectable to the second part, and the
second part can include a space having a variable size. The variable size
of the space can be determined by the position of the first part relative
to the second part. The supporting part can be sized and configured to
engage the space of the handle for allowing selective positioning of the
supporting part relative to the handle part. The guide part can be
connectable to the supporting part with the guide part being operative to
align a tool for use in the dental treatment.
