Evaluation of symphysis donor site quantity by cone-beam computed tomography and its relation to anterior loop of mental foramen: an observational study

The mandibular symphysis bone block graft can be reliably selected as the donor site for a number of different augmentation procedures. However, there are restrictions owing to surrounding anatomical structures such as mental foramen and anterior loop. These vital structures should be considered using accurate CBCT evaluation. Presenting anterior loop of mental foramen is limiting symphysis bone block graft length and volume.
