INTRODUCTION Dental extraction many a time is ensued by bone remodeling process resulting in horizontal and vertical bone ridge reduction [1]. In cases where these ridges have been edentulous for a long time, insufficient residual bone volume may menace the optimal dental implant rehabilitation [2]. Hence, subsidiary surgical procedures may be executed to dispense the alveolar ridge with ample width and height to allow for the prosthetically driven implant placement. Therefore, several surgical techniques have been used to increase the residual bone volume, prior to or during implant placement [3]. Among these techniques, guided bone regeneration (GBR), ridge splitting, block graft (BG), or distraction osteogenesis remain the main methods to reconstruct atrophic ridges [4]. Autogenous bone is accoust to be the gold standard for grafting materials as it brings forth osteo conductive effects from growth factors contained in the graft [5]. For large autogenous grafts, intraoral and extra-oral donor sites have been used. These include the iliac crest, tibia, ramus and chin [4]. Harvest of autogenous bone from these sites requires a second surgery site and involves significant risk of neurological and vascular adverse events and post-surgery outcome [6]. Mandibular fracture has been reported during ramus and chin block grafting [7]. Allograft bone blocks (cortical or cancellous) are among one of the most foreseen procedures [8]. They can also be used in patients with congenitally missing tooth who may present with underdeveloped alveolar ridges [9]. Advantages are as follows:  They do not require a second surgery for autogenous bone block.  Quantity of bone block is not limited like in autogenous blocks.  Discomfort and morbidity to the donor site are avoided.  Therefore, it can be used as an alternative to autogenous bone which requires another surgery to harvest the graft and thus long chairside time. CASE REPORT A 22year male patient reported to the department with a chief complaint of missing teeth in maxillary anterior region which he wanted to get replaced with an implant. On clinical examination deficient horizontal defect was seen with a depth of 4mm and width of 8mm, so it was determined that horizontal ridge augmentation was needed to allow implant placement in a desired position in this site.
