5. WELL-DEFINED INCISAL EMBRASURES In an aged or worn dentition caused by incisal loss of length, the incisal embrasures become smaller or may even disappear. To create a youthful smile these teeth have to be lengthened & the embrasures need to be recreated. The incisal embrasure between the central incisors are the smallest in size & the sharpest in shape. The incisal embrasure between the Centrals & the laterals are relatively larger with a wider angle. The largest incisal embrasure lies between the lateral & the canine.
CASE REPORT:
A 72-year old lady visited our clinic complaining of thinned down & discoloured central incisors .She wanted to restore her two central incisors back to its full length & thickness. On examination her smile had a flat reverse curve due to incisal edge loss. The Central Incisors had thinned down incisal edges, the left central incisor had a discoloured class 3 filling, and the inner chromatic dentin was stained palatally giving the tooth a brownish appearance.
TREATMENT PLAN:
1. Removal & replacement of the old composite restoration in 21.
2. Restoring the thinned enamel & incisal edges in 11, 21 with LiDi laminates of low translucency to match the adjacent PFM restorations
PROCEDURE:.
A digital mock-up was done & shown to the patient using DTS Pro software (Fig8.1) to help her visualise the post-op result in a better way. The same results were transferred in her mouth with the help of a wax mock-up(Fig8.2,8.3,8.4) & the incisal edge position was reconfirmed with the help of phonetics, videos & photos.
0.5 mm depth cuts were made through the temporaries for a conservative prep (Fig9.1), the old Cl3 was replaced & immediate dentin sealing was also carried out at this stage. The prep was modified such that the Cl3 was included in it. This ensures that there is no marginal leakage
& discolouration around the veneer in future. Impressions were made using A silicone putty & light-body with a single step. Both Upper, Lower impressions & an Alu wax bite was sent to the lab and the patient was temporised using the same putty index.
Rubber dam isolation was carried out. The veneers were cleaned thoroughly & stabilised using a putty bed. This was followed by etching the intaglio surface of the veneer with 9%HF for 10-15 secs followed by rinsing & air drying. This was followed by applying a coat of the silane coupling agent.
As the prosthesis was now ready for bonding the intraoral steps for bonding were carried out. 37% phosphoric acid was applied to the tooth surfaces of the central incisors for 20 secs. followed by rinsing thoroughly & the surface was air dried. Universal bonding agent (Single bond universal 3M) was applied & air dried to a thin uniform layer.
