A polyvinyl siloxane putty index (Affinis; Coltene) was fabricated with the existing crown that was anatomically intact before the extraction [Figure 1a]. A screw-retained polyetheretherketone (PEEK) based interim abutment was placed on the implant [Figure 1b] and the hole was created in the putty index corresponding to the abutment screw access hole [Figure 1c]. Teflon tape and an interim abutment was picked up using a Bisacryl resin (Protemp 4; 3M ESPE) [Figure 1d]. The interim abutment was then attached to the laboratory analog and flowable composite resin (Z350 XT Flowable, 3M ESPE) was added to fill up the voids and the emergence profile was shaped using composite finishing kit. The interim restoration was finished and polished [Figure 1e] and screwed onto the implant [Figure 1f].

A 27-year-old woman reported with a history of trauma, leading to a fracture of her right maxillary central incisor [Figure 2a]. A PEEK-based interim abutment was placed [Figure 2b]. The polycarbonate shell crown (3M ESPE) of the most appropriate size was selected from the available stock [Figure 2c] and tried over the abutment for possible adjustments and fitting. The voids were filled-up with flowable composite resin [Figure 2d]. The restoration was finished and polished using composite finishing and polishing discs (Soflex, 3M ESPE) [Figure 2e] and the interim crown screwed onto the implant [Figure 2f].

A 55-year-old man reported with a dislodged prosthetic crown on the maxillary left canine [Figure 3a]. The PEEK interim abutment was placed on the implant [Figure 3b] and the crown was adjusted and perforated corresponding to the abutment screw access hole [Figure 3c]. The abutment was then picked up with Bisacryl resin (Protemp 4; 3M) as described in technique 3 [Figure 3 d and e]. The finished and polished crown was screwed onto the implant [Figure 3f].

A 42-year-old woman reported with a veneered tooth that was fractured at gingival level during a car accident [Figure 4a]. A PEEK interim abutment was placed over the implant [Figure 4b]. The veneer was carefully separated from the bonded tooth by trimming the tooth portion from the palatal aspect using the diamond rotary instruments [Figure 4c] and positioned onto the interim abutment. The height of the abutment was trimmed to accommodate the veneer [Figure 4d]. The flowable composite resin was light polymerized and the whole interim crown was unscrewed and placed on the laboratory analog [Figure 4e]. The excess resin was trimmed off, finished, and polished [Figure 4f] and the crown was screwed onto the implant [Figure 4g].

A 46-year-old male visited with a concern of traumatic injury to anterior teeth resulted in the fracture of his maxillary right central incisor at gingival level and partial fracture of left central incisor [Figure 5a]. Titanium interim abutment was placed [Figure 5b]. The broken natural crown was trimmed from the palatal aspect to keep the facial surface intact [Figure 5c] and positioned in relation to the interim abutment. The height of the abutment was trimmed to accommodate the crown [Figure 5d]. The crown was sequentially treated with a phosphoric acid etchant and a bonding agent and subsequently picked up along with the interim abutment using flowable composite resin similar to technique 4 [Figure 5e]. After finishing and polishing [Figure 5f], the interim crown was screwed onto the implant [Figure 5g].

The maxillary right central incisor of a 65-year-old male was fractured at the cervical level [Figure 6a]. The root was removed with partial extraction therapy and an implant (Biohorizons) of size 4.2 mm x 15 mm was placed immediately in the socket [Figure 6b]. A closed tray (alternately open tray can be used) impression of the implant was made [Figure 6c]. The final stone cast was fabricated, and an interim crown was fabricated with composite resin in the laboratory [Figure 6d]. The interim crown was screwed onto the implant [Figure 6e].
