Inarticulation of complete dentures processed by the compression molding technique

Changes in Vertical Dimension of Complete Dentures due to Rebasing with Different Techniques

“…If at all there is plethora of doubt in mind with regards to the shift of teeth in processed dentures, it has been addressed in this project work. A number of variables in respect of changes in occlusion 1,[3][4][5][17][18][19][20][21][22] have been widely debated.…”

“…It has been observed that the commonly followed compression molding procedure causes migration [1][2][3][4][5] of artificial teeth in the mold. The resultant shift adversely affects the planned occlusion which is manifested by the loss of incisal pin contact with the incisal table of the articulator.…”

Influence of different metal flask systems on tooth displacement in complete upper dentures

“…Teeth could be an important factor in the distortion of dentures, as small changes in tooth position may sometimes cause an increase in the vertical dimension. A previous study reports that a 1.0‐mm increase in the incisal guide pin may be the result of 0.25 mm in tooth movement 10 . Many other factors may interfere with tooth displacement, such as flask cooling method 11 , base thickness 12 , curing cycle 13 , mould expansion 14 , type of commercial acrylic resin 15 , flask closure system 16–18 , flask cooling method 11 and deflasking 19 .…”

Teeth movement in denture and implant-supported prosthesis influenced by microwave flask systems

“…A dimensional vertical change of 0.25 mm in the posterior region would result in an increase of 1 mm in the vertical position of the incisal pin. 4 In addition, the teeth displacement 3,5 can also cause interferences that induce traumatic occlusion, responsible for the irregular distribution of stresses to the support tissues, causing discomfort and affecting the patient's masticatory function. Dimensional changes of the acrylic resin base occur during the polymerization and deflasking procedure.…”
