Matriz extracelular para manejo de alvéolos st1 y st2 serie de casos

Abstract

Introduction: Post-extraction alveolar ridge dimensional loss represents a clinical challenge because it may compromise bone availability for future rehabilitative procedures. Alveolar preservation and regeneration techniques minimize these changes through the use of biomaterials that promote clot stability and maintenance of the alveolar contour. Extracellular matrix has attracted interest due to its biocompatibility and its potential to support cell migration and proliferation. Objective: To assess dimensional changes in ST1 and ST2 sockets treated with extracellular matrix in patients treated at the dental clinics of Santo Tomás University in Bucaramanga, Colombia, through tomographic follow-up at 3 and 6 months. Materials and Methods: A descriptive case series was conducted. Nine extraction sockets treated with extracellular matrix were analyzed, including five ST1 and four ST2 sockets according to the Steigmann classification. Radiomorphometric measurements were obtained from baseline, 3-month, and 6-month tomographic scans. Dimensional changes were evaluated in comparison with baseline measurements. Results: The sockets exhibited favorable radiomorphometric outcomes. ST1 sockets showed greater dimensional stability, whereas ST2 sockets demonstrated greater variability in the cervical and central regions, possibly associated with buccal fenestration. Conclusion: Extracellular matrix demonstrated promising clinical and radiomorphometric performance in the management of ST1 and ST2 sockets. Due to the small sample size and the absence of a control group, these findings should be considered preliminary evidence. Controlled studies with larger sample sizes and long-term follow-up are required.
