32-year-old patient with no relevant medical history was referred to us having lost an implant on tooth 46 following an infection.
The patient presented with a very pronounced defect with a height to the dental nerve of 2.40 millimetres, which precluded the placement of short implants.
We discounted the possibility of lateralisation of the dental nerve due to the extent of hypaesthesia in the nerve, and the poor quality of the soft tissues, being difficult to improve at such a height.
Extended defect

We proceeded to perform bone augmentation surgery with the 3D reconstruction through tunnelisation technique, using autologous bone taken from the mandibular rmus and conforming it as described by said technique.
You can see the implant surgery 1 year after the graft in this post.
