Zygomatic bone is one of the facial bones, which forms the prominence of the cheek. It helps in formation of walls of bony orbit, temporal, and infratemporal fossa. Nowadays, the importance of this bone is highlighted in several clinical conditions. In dental implants, when there is no adequate bone volume permitting their anchorage, zygomatic implants are long screw-shaped implants developed as a partial or complete alternative to bone augmentation procedures for the severely atrophic maxilla.1 The potential main advantages of zygomatic implants could be that bone grafting may not be needed and a ?xed prosthesis could be ?tted sooner.Cone Beam Computerized (CBCT) of 30 patients (15 males and 15 females) above 40 years of age who underwent radiological evaluation for implant placement in posterior atrophic maxilla were selected as the study participants with edentulism for more than 1 year. The inclusion criteria of the study was partially edentulous or completely edentulous patients with maxillary atrophied posterior region. The exclusion criteria was tumours, trauma and those with systemic complications. Informed consent was obtained from the patients before radiograph.In the study population, 39.2% were males and 60.7% were females. In relation to CBCT variation of zygomatic bone length among males. Most prevalent (30%) zygomatic bone length is observed to be 40mm females. Most prevalent (50%) zygomatic bone length is observed to be 43mm among males. Most prevalent (50%) zygomatic bone width is observed to be 4.5mm to among Females. Most prevalent (30%) zygomatic bone width is observed to be 5 mm among males. Within the limits of the study it was found that the majority of male population 30% has zygomatic bone length 40mm and in Female population 50% has 43 mm. Most prevalent (50%) zygomatic bone width is observed to be 4.5 mm and 5mm in females (30%).
