Résumé
ABSTRACT: Progressive periodontal disease causes loss of supporting structures of teeth resulting in deep bony defects. In this case a report of 22-year old female patient is being presented with clinical findings of vertical bone loss in two adjacent teeth, on distal surface of 2nd upper right premolar and mesial surface of upper right 1st molar. Root canal treatment, non-surgical periodontal therapy followed by guided tissue regeneration was carried out using decalcified freeze-dried bone allograft (DFDBA) and collagen membrane. Analysis of clinical and radiographic findings showed marked reduction in pocket depth up to 12mm with hard tissue repair on 3-month, 2-year and 5- year follow ups.
RESUMEN: La enfermedad periodontal progresiva provoca la pérdida de las estructuras de soporte de los dientes, lo que resulta en defectos óseos profundos. En este caso clínico se presenta un informe de una paciente de 22 años con pérdida ósea vertical en la superficie distal del segundo premolar superior derecho y en la superficie mesial del primer molar superior derecho. El tratamiento del conducto radicular, la terapia periodontal no quirúrgica seguida de la regeneración tisular guiada se llevó a cabo utilizando aloinjerto óseo liofilizado descalcificado (DFDBA) y membrana de colágeno. El análisis de los hallazgos clínicos y radiográficos mostró una marcada reducción en la profundidad de la bolsa de hasta 12 mm con reparación de tejido duro en seguimientos de 3 meses, 2 años y 5 años.

The interface of ligaments, tendons, and bones are susceptible to damage, often fail to heal themselves, and even cannot achieve a good prognosis after surgery. Interface tissue engineering is a comprehensive strategy to functionally connect soft and hard tissues to regenerate original anatomical functions and structures, thereby improving clinical efficacy. In this paper, the interface tissue engineering and composite tissue regeneration in soft tissue healing were systematically reviewed. The recent advances in interface engineering were summarized, based on the treatment of structural damage from two common soft tissue-bone connections (ligamentous bone connections, tendon bone connections), from the development of single tissue to composite tissue structures. The latest interface tissue engineering innovation structure design and potential clinical applications in recent years were reviewed. For future research, in-depth research on the mechanisms of interface development, regeneration, and internal environment balance, structure-function relationships, and biological processes that drive interface development, regeneration, and internal environment balance are still necessary. The innovative studies on interface tissue engineering have promoted the significance of the integration of tissue engineering and clinical, and the construction of complex tissues, so that it has broader significance for the future regeneration of total joints.
