Predictable and effective surgical techniques that aim to increase the width of keratinized gingiva, relocate the mucogingival junction, and deepen the vestibule often involve soft tissue autografts; however, soft tissue autograft supply is limited and its harvesting is associated with patient morbidity. With a strip autograft and xenogeneic collagen matrix (XCM) technique combination, autograft harvest requirements and patient morbidity are reduced. In this histologic evaluation, 12 strip autograft/XCM biopsy samples were compared with 3 reference samples of palatal strip autografts. Tissue morphology, keratin, and collagen expression appear identical, indicating that the combined grafting technique provides desired and physiologically normal keratinized gingiva.
旨在增加角化龈宽度、重新定位黏膜牙龈交界并加深前庭沟的可预测且有效的外科技术通常涉及软组织自体移植；然而，软组织自体移植的供体有限，且其采集与患者的发病率相关。采用带状自体移植与异种胶原基质（XCM）技术相结合的方法，可减少自体移植的采集需求和患者的发病率。在本次组织学评估中，将12个带状自体移植/XCM活检样本与3个腭部带状自体移植的参考样本进行了比较。组织形态、角蛋白和胶原蛋白表达看起来相同，这表明联合移植技术可提供理想的、生理上正常的角化龈。
