The most time-saving and aesthetic restoration type is an immediate temporary crown attached to the implant. However, this practice needs an insertion torque of 30 Ncm or more. This case did not meet this criterion. Therefore, the idea of using the coronal part of the extracted tooth as a temporary restoration was con- sidered. The gum level was marked with a permanent pen just before extraction (Fig. 4). Due to an extensive deep bite, there was no room to use a fibre splint in order to achieve retention via the neighbouring teeth. The only remaining alternative was to attach the extracted coronal part using light- cured composite. One of the neighbouring teeth and the extracted coronal part was carrying a ceramic laminate, whereas the tooth #22 was yet untreated. Therefore, the glazed surface of the ceramic resto- rations was roughened with diamond burs and nine per cent HFl acid was applied, followed by silane and bond application (Fig. 5). On the natural enamel of tooth #22 only orthophosphoric acid of 36 per cent was used for 30 seconds followed by a composite bonding material application (Fig. 6). The patient was advised to follow a soft diet and discharged (Fig. 7). During the three-month healing period, the crown was de- attached twice. However, these appoint- ments were also considered as an advantage as it al- lowed the clinician to add light curing composite ma- terial beneath the extracted crown. This way, a better crown profile was attained. When osseointegration was achieved, the soft-tis- sue loss was minimal and an acceptable tissue con- tour was observed (Fig. 8). The insertion angle of the implant was checked (Fig. 9). In order to not damage the delicate soft tissue which could cause aesthetic problems, the cover screw was removed without sur- gical intervention (Fig. 10). An open-tray impression post was inserted, an X-ray was taken to verify the fit Fig. 11a Fig. 11b Figs. 11a & b: Insertion of an open-tray impression post and X-ray. 24 implants 3 2017
