Abstract

In cases of severe alveolar bone atrophy in the posterior maxillary area, which has only a thin sinus floor, the autogenous tooth bone graft block (ABTB) was used to wrap the implant to enhance its primary stability and osseointegration in the sinus. These cases with four years of clinical follow-up demonstrate the applicability of the ABTB in maxillary sinus membrane elevation to improve the outcomes of implant placement.

  • Fig. 2 The occlusal view of the autogenous tooth bone graft block, which was made from the root portion of the extracted tooth.

  • Fig. 3 The sinus lateral window was opened and the membrane was elevated.

  • Fig. 4 The autogenous tooth bone graft block was adapted onto the implant.

  • Fig. 5 The autogenous tooth bone graft block was adapted into the sinus.

  • Fig. 6 The implant was simultaneously installed through the alveolar bone and into the autogenous tooth bone graft block.

  • Fig. 7 The lateral window was repositioned.
