Figures & Tables

Figure 1.

(A–C) Pretreatment extra-oral photographs. (D—H) Pretreatment intra-oral photographs.

Figure 2.

(A) Pretreatment dental panoramic radiograph. (B) Periapical radiograph showing resorption on the apical surfaces of #12 and #21. (C) Lateral cephalogram. (D) CBCT section showing developing tooth #45 with ¾ root length.

Figure 3.

(A) Periapical radiograph taken 2 weeks post-autotransplantation. (B)Transplanted tooth secured with a flexible wire splint. (C) Composite build-up of the transplanted tooth 1-month post-autotransplantation.

Figure 4.

(A–E) Midtreatment intra-oral photographs.

Figure 5.

(A-C) Posttreatment extra-oral photographs. (D-G) Posttreatment intra-oral photographs.

Figure 6.

(A) Posttreatment panoramic radiograph. (B) Periapical radiograph of transplanted tooth showing good root length and pulp canal obliteration. (C) Lateral cephalogram. (D) 4-year follow-up of the transplanted tooth #45 showed blunting of the root apex and a localized concavity on the mesial aspect of the root. The tooth should be reviewed in the longer term to assess for any developing signs of root resorption.

Figure 7.

(A-C) Pretreatment extra-oral photographs. (D-H) Pretreatment intra-oral photographs.

Figure 8.

(A) Pretreatment panoramic radiograph. (B) Periapical radiograph showing decoronated #11 and crown attached; Resorption on the apical surfaces of #12 and #21. (C) Lateral cephalogram. (D) CBCT section showing developing tooth #35 with ⅔ root length and (E) Developing tooth #45 with ¾ root length.

Figure 9.

(A) Periapical radiograph taken 1 week post-autotransplantation; teeth #35 and #45 secured with a flexible wire splint. (B) Lower second premolars transplanted into the anterior maxilla region. (C) Composite build-up 2 months post-autrotransplantation.

Figure 10.

(A-E) Midtreatment intra-oral photographs.

Figure 11.

(A-C) Posttreatment extra-oral photographs. (D-H) Posttreatment intra-oral photographs.

Figure 12.

(A) Posttreatment panoramic radiograph. (B) Periapical radiograph of autotransplanted teeth showing good root length and pulp canal obliteration. (C) Lateral cephalogram. (D) 4-year follow-up of the transplanted teeth showing adequate root lengths and optimal intra-crestal bone levels. Pulp canal obliteration was seen in both transplanted teeth.
