Aim: The ultimate aim of this study was to evaluate the bone changes following immediate dental implant placement with autogenous bone graft at different time internals. Materials & Methods: This study was designed on prospective ideology and attempted genuinely in male and female patients of 25 years to 45 years. All patients with any kind of anomaly related to head and neck region was excluded from the study. All patients with any underlying systemic diseases were also taken as exclusion. At first, a total of 10 patients were selected those undergone replacement of single missing anterior teeth with immediate implants with autogenous bone graft. The alveolar bone loss was evaluated radiologically using cone beam computed tomography. This was attempted on different time intervals of 3 months, 6 months and 9 months. Informed consent was obtained from the patients those were willingly ready for participation. All four surfaces i.e; mesial, distal, buccal and lingual was analyzed for bone loss/levels by cone beam computed tomography. Statistical Analysis and Results: Statistical analysis was attempted by statistical software Statistical Package for the Social Sciences (SPSS). The obtained data was sent to appropriate statistical tests to achieve p values, mean, standard deviation, standard error an 95% CI. P ≤ 0.05 was considered as statistically significant. Out of 10 patients, males were 5 and females were 5. All selected and studied patients were divided into 4 age groups. 3 patients were falling in the age range of 25-29 years. 3 patients were falling in the age range of 30-34 years. Consequently we can presume that majority of the studied patients were of first two age groups. P value was found to be significant in group I & IV of age range 25-29 and 40-45 years. The calculated p value was 0.02 and 0.01 respectively. Conclusion: Within the limitations of the study, the authors concluded that there was noticeable bone loss on almost all surfaces of all studied immediate implants cases. Furthermore, these bone losses were in increasing pattern when seen after three months, six months and nine months of post operative phases with autogenous bone grafts. CBCT estimation also verified these bone losses accurately. These types of small and accurate detail can only be expressed by cone beam computed tomography.
