Distracción osteogénica del reborde alveolar: revisión de la literatura
Uno de los principales problemas para la colocación de implantes dentales es la presencia de hueso insuficiente que impide que sean de una longitud y/o de un diámetro adecuados. Dentro de los métodos que se usan para el aumento del reborde alveolar se incluye tan solo desde hace una década la aplicación de los principios de distracción osteogénica (DO). Esta técnica se basa en la separación gradual de dos fragmentos de hueso perfectamente vascularizados, entre los que se forma un callo de distracción que progresivamente se transforma en hueso maduro. Un científico clave en el desarrollo de esta técnica fue el traumatólogo ruso Ilizarov. Esta revisión bibliográfica evalúa la metodología, el …
Immunohistochemical Evaluation of Periodontal Regeneration Using a Porous Collagen Scaffold.
(1) Aim: To immunohistochemically evaluate the effect of a volume-stable collagen scaffold (VCMX) on periodontal regeneration. (2) Methods: In eight beagle dogs, acute two-wall intrabony defects were treated with open flap debridement either with VCMX (test) or without (control). After 12 weeks, eight defects out of four animals were processed for paraffin histology and immunohistochemistry. (3) Results: All defects (four test + four control) revealed periodontal regeneration with cementum and bone formation. VCMX remnants were integrated in bone, periodontal ligament (PDL), and cementum. No differences in immunohistochemical labeling patterns were observed between test and control sites. N…
Pre‐clinical evaluation of the effect of a volume‐stable collagen matrix on periodontal regeneration in two‐wall intrabony defects
Aim To histologically evaluate the effect of a new collagen matrix on periodontal regeneration. Materials and methods Two-wall intrabony defects were surgically created bilaterally distally to the maxillary first and third pre-molars in beagle dogs. The defects were randomly allocated to open flap debridement either with (test) or without (control) a volume-stable collagen matrix (VCMX). After 12 weeks, the dogs were euthanized, and the specimens histologically processed. Descriptive, histomorphometrical (vertical gain of periodontal tissues) and statistical analyses were then performed. Results Healing was uneventful in most cases. Residual VCMX was still present and showed integration int…
