RESUMO
Aim: This study aimed to evaluate the efficacy of dehydrated amnion allograft with coronally positioned flap procedure in paired Miller's class I recession defects. Methods: A total of 51 subjects were included in the study with bilateral Miller's class I gingival recession defects. In the test group, patients were treated with an amniotic membrane (AM) with a coronally positioned flap, while in the control group, patients were treated with coronally positioned flap alone. Clinical parameters such as recession depth, recession width (RW), probing depth (PD), relative attachment level (RAL), width of keratinized gingiva (WKG), and thickness of keratinized gingiva (TKG) were recorded at baseline and after 5 years of follow-up. Result: The mean baseline recession was 2.95 ± 0.89 in the test group and 2.70 ± 0.85 in the control group, and both were statically non-significant. At the end of 6 months, all the parameters, when compared with the baseline, showed a significant improvement. Intergroup comparison showed the non-significant difference in all settings except the TKG. Conclusion: AM proved to help improve the TKG. This increase in thickness helps in the long-term maintenance of the gingival margin in Miller's class I recession defect.
RESUMO
AIM: The study aims to clinically and radiographically compare the bucco-lingual crestal bone changes after immediate and delayed placement of implants. METHODS: Two groups that consisted of fifty implants were considered for this study. In group A the implants were placed immediately post extraction, whereas, in group B implants placement were delayed by four to six weeks. All the implants were submerged within the alveoli confines. Bone grafts were only placed if the jumping distance was more than 1.5 mm. Barrier membrane was not placed in any of the cases. Bucco-lingual width was measured at the time of implant placement and during abutment placement after four to six weeks. Primary flap closure was ensured in all the cases. RESULTS: Thirty-one implants were placed in the mandible and nineteen were placed in the maxilla. All the implants achieved osseointegration. Immediate implant group showed a mean width of 8.80 mm (SD2.280) at the time of implant placement whereas, 7.60 mm (SD 1.871) after six months. Delayed implant group showed a mean width of 8.40 mm (SD1.673) at the time of implant placement, and 7.40 mm (SD 1.658) after six months. Intragroup showed statistically significant data (P<0.05). When the intergroup comparison of group 1 and group 2 was made at implant placement day and abutment placement day, it was found to be statistically non-significant. CONCLUSION: This study suggests that circumferential defect heals on itself without any guided bone regeneration in both the groups. The data suggests that the healing in both the group were equally good. The equally good results suggest placing the implant immediately post extraction. This saves the cost, time and most importantly the need for an extra surgery.
