Advantage of subgingival preparation


This is case with a full ceramic restoration with supragingival preparation. eventhough the book prescribes a supragingival preparation in non-esthetic region, if prefer subgingival preparation, because of this above picture.the problem with this that there is possibility of food accumulation or plaque formation, which if the patient not aware this leads to gingivitis which drastically reduces the tone of gingiva and increases the depth of the sulcus from which there is no turn back other than offering a new crown. so ot os better to give a equigingiva or subgingival preparation.


The picture above shows the subgingiva preparation. Tell the patient about its important in maintanance. the maintance is simple. tell the patient to massage the gingiva from the gingiva towards the crown after brushing with the paste as lubricant. by this way it enhances the tone of the gingiva and prevents any accumulation of the debris in the subgingival region.
