Base plate wax used for teeth arrangement is amorphous in nature and its manipulation complete denture problems articulation of teeth induces stresses. Waxes are sensitive to temperature changes and shrink considerably upon cooling, inducing more stresses.

These stresses and the resulting strains cause tooth movement. This movement will disturb the planned denture occlusion.

Addressing problems in complete dentures.

It has been suggested that a suitable synthetic wax with constant physical properties and a spray of thin plastic film capable of instantly holding the teeth in desired positions in wax complete denture problems be of great help in preventing tooth movement [ 24 ].

Also the waxed trial dentures must be flasked immediately to avoid any changes due to wax expansion or contraction.

Flasking and type of investing material There is evidence to indicate that vertical shifting of teeth occurs complete denture problems investing. Expansion of and heat liberated by the setting investing material second pour is sufficient to move the teeth in wax [ 25 ].

Grant had shown tooth movements of 0.

He also suggested that distortion of the original gypsum cast, resulting from pressures developed during processing, induced further errors in complete denture problems [ 26 ]. Tooth displacement could however be decreased because the plaster set expansion will compensate partially for the polymerization shrinkage of acrylic resin [ 12 ].

Many studies have evaluated the relationship between the investing material and the vertical occlusal changes that occur during processing [ 14 - 18 ]. The materials studied were; laboratory silicone, used as a layer to cover all the complete denture problems teeth and an all gypsum investing technique.

Except Marcroft, [ 14 ] who reported occlusal accuracy obtained with a layered silicone rubber mold to be markedly superior to that of the usual method of processing in complete denture problems molds made of gypsum products, all the others did not report any significant difference in vertical tooth movement between the two materials [ 15 - 18 ].

Different results have been obtained regarding the influence of silicone on linear displacement of teeth. Mainieri [ 15 ] had reported that the horizontal movement of teeth was more lingual in the silicone technique. Lechner however, reported that investing material does not influence linear distances anteroposterior as long as artificial teeth can be kept in position by the virtue of the existence of mesio-distal contacts [ 27 ].

It is well known that use of stone matrix will help prevent shifting of the teeth during complete denture problems and facilitates easy separation of the investment from the finished denture. Another factor that can cause dimensional change in resin is the monomer-polymer complete denture problems.

Addressing problems in complete dentures.

Higher polymer content can yield a dry mixture, resulting in a material mass with complete denture problems to convert monomer into polymer. Alternately, excess monomer content may produce higher complete denture problems due to excessive polymerization. It was hypothesized that changes in monomer-polymer ratio from that recommended by the manufacturer might cause linear displacement of teeth.

However, the results did not report any change [ 23 ].
