Without a proper intervention, a crushed alveolar process fracture can cause significant dimensional changes on affected hard and soft tissue that lead to difficult circumstances for post traumatic bone augmentation and dental implant placement. We present herein the cases of immediate guided bone regeneration ( GBR ) for the maxillary anterior alveolar process with comminuted fracture. Shortly after the hospital visit, guided bone regeneration was conducted for three patients using only xenograft material and bone fragments from traumatic site, without an additional donor site. Resorbable collagen membrane was used on the bone graft site, and titanium mesh was also used if significant bone loss were expected. Radiographic evaluation 6 months after GBR confirmed that all three cases had sufficiently preserved alveolar bone which is clinically required for implant placement. Dental implant installation was carried out for two patients and no specific findings were noted in follow‐up after the placement. In this method, additional operation sites for bone collection are not necessary and the number of surgical steps before implant placement can be reduced. Furthermore, this immediate intervention can effectively minimize the alveolar ridge shrinkage of anterior maxilla after injury.
