Thank you for choosing Coltène/Whaledent's Pindex
system. It has been designed and manufactured to provide you with
many years of reliable service.
The Pindex System is designed to assist in fabricating accurate
models and dies for use in the fabrication of dental restorations.
The Pindex System is used to accurately drill parallel holes into
the underside of the model. Precision Pindex Pins may then be
cemented into the parallel holes. Pins are selected based on
space available.
Precision pinning of dies and sections of the master model allows the
technician to disassemble and reassemble the model repeatedly
and accurately to facilitate the fabrication of restorations.
This owner's guide will provide step-by-step instructions for the
production of accurate models and dies.
I. Pre-drilling instructions
1. Master model is poured in stone or epoxy (Fig. 1).
2. Model base is trimmed perfectly flat on model trimmer
(Fig. 2), so that the model thickness from base to prepara-
tion margins is approximately 15 mm (Fig. 3).
3. Sections and dies are pre-planned and pin locations are
marked with a pencil on tooth side of model (Fig. 4) prior to
drilling holes (Fig. 5).
4. When two pins are in close proximity, it is important to allow suf-
ficient space for the placement of the sleeves (Fig. 6). If this is
not possible, a dual pin or Tri-Plus pin should be used (Fig. 7).
5. Each die or section must have either two pins or a dual pin
(Fig. 13).
II. Drilling pin holes
1. For best results use a slightly moist model.
2. Turn switch on; red pilot light will glow brightly.
3. Place model on work surface and align pencil marks with
the illuminated dot (Fig. 5).
Firmly hold the model with both thumbs and grasp the large
black ring with the remaining fingers. Slowly squeeze with even
pressure, allowing entire work table housing to slide downward
until the end stop is reached (the light will automatically switch
off). Sequentially drill all holes to full depth. Do not force;
advance slowly and let the drill do the cutting.
4. After all holes have been drilled, each hole which is to
receive a dual pin or Tri-Plus is notched lingually with a thin
separating disc (Fig. 8, 9 and 10).
5. The model and holes are thoroughly cleaned of debris with
compressed air.
III. Placing pins and sleeves
1. Place a small amount of cyanoacrylate cement into a
depression in a small piece of soft wax (Fig. 11).
2. Each Pindex Pin is lightly dipped into the cement and seated
into the appropriate pin hole. For convenience and accessibility,
the short Pindex Pins and dual pins are cemented first (Fig. 12).
The dual pin must be aligned so that the anti-rotational rib fits
into the groove in the model (Fig. 12). The long Pindex Pins are
then cemented into place (Fig. 13).
