Figure 1 . Pre-treatment radiograph indicating split tooth #19 and significant infection around its mesial root and distal root surface of tooth #20.
Figure 2 . Extracted tooth #19 showing extension of the fracture line and the size of the radicular granuloma.
Figure 3 . A composite image illustrating (a) surgical closure using the socket seal technique after extraction of tooth #19 and (b) socket fill following extraction with radiolucent gap on the distal root surface of tooth #20, which represents pre-medicated collagen sponges.
Figure 4 . A composite figure illustrating (a) clinical view of site #19 6 months following extraction and GBR procedures and (b) radiographic evaluation of site #19 showing progressive healing and bone fill.
Figure 5 . Postoperative view of the implant following placement in a two-stage surgical approach.
Figure 6 . Postoperative clinical view of the implant site following closure of the surgical hole using the excised native soft tissue.
Figure 7 . Postoperative clinical view of the screw-retained implant crown following insertion.
Figure 8 . A composite figure illustrating clinical views of the implant-supported crown from the (a) buccal and (b) lingual aspects 2 years after treatment completion.
Figure 9 . CBCT radiograph obtained the year following completion of treatment, indicating progressive bone gain around the implant and the distal root surface of tooth #20.
Figure 10 . CBCT radiograph obtained 2 years following completion of treatment indicating adequate bone fill and maturation around the implant and distal root surface of tooth #20.
