Introduction: Sufficient volume of bone is of prime importance for successful osseointegration of dental implants. Mandibular ramus acts as a good source of cortical bone graft without much complications, as seen most commonly while harvesting bone graft from mandibular symphysis or body. Aim: To evaluate maximum extent and different dimensions (length, height, thickness, surface area and volume) of cortical bone graft that can be harvested from ascending ramus of mandible maintaining safe zone from anatomical vital structures by using CBCT. Materials and Methods: The retrospective CBCT analytical study has been carried out in the Department of Oral and Maxillofacial Surgery, Guru Nanak Institute of Dental Sciences and Research, Kolkata, West Bengal, India. CBCT of 30 patients have been used to study 55 sites of ascending ramus of mandible. The CBCTs have been collected from Institutional archive. The studies were done in NNT viewer software. Results: The mean length of cortical bone graft that can be harvested from mandibular ramus was found to be 14.49±2.66 mm, whereas the mean height and thickness was 6.40±2.07 mm and 3.04±0.61 mm respectively. The mean surface area was found to be 308.88±75.37 sq mm, whereas volume was 272.15±92.02 cu mm. Each of the dimensions were compared among genders, sides and different age groups (18-29 years, 30-45 years and 45 years age group). Statistically significant difference was found for surface area and volume among genders, with males having greater dimension than female. Conclusion: Mandibular ramus can be a great option for harvesting cortical bone graft for alveolar ridge augmentation procedures. [ABSTRACT FROM AUTHOR] |
