ABSTRACT
Introduction: Preservation of alveolar dimensions after tooth extraction is crucial to achieve optimal esthetic and functionalprosthodontic results. With the increasingly frequent use of dental implants to replace non-restorable teeth, preservation ofthe existing alveolus is essential to maintain adequate bone volume for placement and stabilization of the implants. The aimof the study was to clinically and radiographically compare and evaluate autogenous dentin as bone graft with demineralizedfreeze-dried bone allograft (DFDBA) and extraction socket left alone for healing.Materials and Methods: Ethical clearance was obtained for the study. A written informed consent was taken from all theparticipants. A total of 45 randomly selected adult patients were divided into three groups: (1) Extraction socket with graftmaterial placement: Autogenous dentin (natural tooth dentin) as a bone graft (15 participants). (2) Extraction socket with graftmaterial placement: DFDBA as a bone graft (15 participants). (3) Extraction socket to be left alone for healing (15 participants).The cases were examined at 3, 6, and 9 months post-intervention. For each visit, clinical and radiographic assessmentradiovisiography was done to access the bone tissue healing. The mean buccolingual bone ridge width and height werecompared both clinically and radiographically. The data collected were subjected to statistical analysis using SPSS 22.0.ANOVA and paired t-test were carried out for comparing the mean bone buccolingually on the radiograph. All P < 0.05 wereconsidered to be statistically significant.Results: The mean buccolingual ridge width measured by Vernier caliper for the I group was 7.13 ± 0.91, for II group, it was6.20 ± 0.86, and for the III group was 5.33 ± 0.61. The difference between the groups was statistically significant at 9 months.The mean height of the bone measured by radiograph showed that for I group, it was 6.33 ± 0.88, for II group, it was 6.13 ± 0.83,and for the III group, it was 5.33 ± 0.61. The difference in the mean outcome was significant between I and III as well as II andIII groups.Conclusion: The results of the grafted sites showed statistically significant difference compared to non-grafted sites.The alveolar ridge preservation shows reduction in buccolingual shrinkage. The present investigation shows thataugmenting the extraction socket with biomaterials may have the possibility to limit the buccolingual and coronalapical shrinkage.
