Introduction : An insufficient dimension of keratinised tissue is related to a shallow vestibular depth in many cases, which may prevent appropriate prosthetic rehabilitation and facilitate plaque retention. Thus, the aim of this study was to compare clinically vestibular extension alone or in combination with PRF membrane or amniotic membrane as graft materials for vestibuloplasty in mandibular anterior region. Materials and Methods: 30 patients were selected based on the presence of shallow vestibular depth and divided into three groups: Group I (vestibular extension), Group II (vestibular extension with PRF membrane) and Group III (vestibular extension with amniotic membrane). Clinical parameters recorded were: Vestibular Depth, Thickness of Keratinised gingiva, Plaque index, Gingival Index, Healing Index & Visual Analog Scale. Results: Amniotic group (p=0.005) showed the best reduction in PI score, whereas control group (p=0.02) showed a statistically significant difference in mean GI score. TKG depicted non–significant results. Mean VD and VAS scores depicted a statistically significant result. Better healing was observed in all the three groups but it was statistically non–significant, with Group III showing better results (p >0.05). Conclusion: Thus, vestibular extension when performed with amniotic membrane showed better results in as compared to vestibular extension alone or when performed with PRF membrane.
