Master-Sep is one of the leading separating mediums in the market today. It is excellent for separating plaster from die stone. It seals the pores of the die stone, this in turn forms a tough protective coating that creates a smooth surface which gives excellent separation. The smooth flow of stone accurately duplicates every detail of the surface and gives a cleaner breakout thus making Master-Sep a perfect insulator and separator between the dental arch and the model base.

Position: Tooth position is a bio-mechanical exercise that dictates lip support and determines the firmness of muscle tone for facial muscle activity.

Dimension:  The clinical practicioner must carefully explain and guide the patient into recognizing there is a harmonious relationship between the size of anterior teeth and the size of the face.  Long teeth create at toothy appearance, small teeth on the other hand shows excessive pink gingival.  Scientific investigation indicates that the upper central should be one sixteenth the facial width for an optimum pleasing appearance.  Individual studies indicate that stock teeth may be too uniform and it would be prudent to select central, laterals and cuspids individually rather than from the carded set provided by some tooth manufacturers.

Shade:  Consider the patient’s age and complexion and select teeth with several shades to give each tooth a distinctive colour and texture.  The closer an object is to the eye, the lighter it seems.  Therefore, professional guidance is necessary to provide the patient with a tentative colour selection and get final acceptance at the try-in stage.

Form:  There is clinical evidence to indicate that harmony between tooth form and the shape of the face  is the exception and not the rule. The system of classifying faces as square tapering and avoid the corresponding carded tooth system attributed to it, may be easy to use and is widely accepted by the dental profession, however, it has no aesthetic merit or scientific basis.  Since there is a lack of natural standardization and the fact the edentulous arches are changing due to tooth removal, surgery and restoration, mold selection whether square tapered or avoid cannot be selected by the from of the residual ridge.  According to A. Nelson, the unchanging from of the central position of the palatal vault is the most reliable clue to the original from of the arch.  Therefore, correct alignment is far more important than correct mold of tooth for the patient.

Alignment:  Arrangement is the most dominating factor related to teeth and their aesthetic influence.  The only correct tooth position is where teeth were in nature.  Start with the maxillary centrals which are always in front of and on either side of the incisive papilla.  Don’t position upper anterior teeth on top of the ridge crest since it will cause facial functional loss.  Also, analyze both the vertical tooth position and the labio- lingual position while establishing phonetics.  The patient’s old dentures provide a lot of information or a photograph showing the natural teeth in a smile is also welcome. Alignment in relating teeth in their long axis or breaking their alignment follow examples found in natural teeth.  From studying natural dentition we can conclude there is a definite relation  between the form of the maxillary arch and the alignment form of the upper anterior teeth.  The arch then indicates the alignment of the natural teeth.

Final Waxing:  the polished surface area of a complete denture influences retention as well as aesthetics.  The wax around the teeth should indicate the form  of the gingival tissues.  Labial surface fullness is desirable without altering the original borders. The lower denture lingual surface should beconcave to provide a resting place for the tongue.  Some festooning can create a natural look. There is no fool proof formula for achieving a perfect result,  however, each clinician following accepted standards of practice can ensure patient satisfaction and make this experience more enjoyable and rewarding for all concerned.
