Restoring function in balanced oral environments Dr Clarence Tam An active 76 year-old partially-dentate patient, presented for treatment. Despite functioning well and satisfactorily with a chrome cobalt partial denture, her chief concern revolved around the closure of the open contact between teeth 34 and 35, while simultaneously treating caries diagnosed on 34D and marginal failure on the MO composite restoration. She reported xerostomia because of the anticholinergic effect of her amitryptaline intake - her home care regime now includes both GC Dry Mouth Gel as well as GC Tooth Mousse Plus®, used morning and evening. All in all, this Essentia™ direct restoration represents what is possible with modern bonded dentistry - the simultaneous achievement of conservation of tooth structure, whilst improving aesthetics at the same time. 1. Pre-operative situation featuring an old composite restoration on 34O and an open contact between 34 and 35 leading to gingival and patient cognitive irritation from the chronic food trap. 2. Excavation of the old restoration and uncovering the top of the proximal carious lesion showing clear extension past the DEJ into dentine. 3. Completed Class II preparation and sectional matrix assembly in place on 34DO. 4. Mini 0.25mm horizontal layers, individually fully-cured were created using A2 G-ænial™ Flo X, for precision lining the base of the Class II proximal box floor and cavosurface region. 5. Marginal ridge layered to full anatomic height using Essentia™ LE. 6. Dentine mass composed of Essentia™ DD placed and sculpted. 7. Essentia™ Modifier RBM was used in the dentine fissures prior to layering of enamel. 8. Mid-Mesial lobe layered using Essentia™ LE. 9. Final post-operative view showing integration with occlusion, closure of open contact and compatibility of contours and restoration with existing chrome cobalt partial denture.
