Atrophic edentulous ridges often pose a challenge for successful rehabilitation using endosseous dental implants. The solution to this is bone augmentation procedures. This case report chronicles the management of an atrophic posterior mandibular ridge by a ridge-split technique along with simultaneous implant placement. It also highlights the importance of maintaining an adequate zone of keratinized mucosa around the implant which was accomplished by means of an apically repositioned flap in the second stage surgery. A two year follow up reveals healthy implants and a fully functional dentition. Hence the ridge-split procedure can provide a simpler approach to augmentation compared to traditional complex techniques that require an additional donor site which raises the risk of morbidity. This approach also reduces the total treatment time which is beneficial for both the patient and the surgeon.
