Comparative analysis of the results of using individual titanium frameworks and resorbable collagen membranes in alveolar bone reconstruction

Abstract

This article describes a method of directed bone regeneration (DBR) of alveolar bone using 3D printed individual titanium framework membranes (ITFMs). Using computer modelling and additive technologies, we have designed and manufactured ITFMs for directed bone regeneration. The use of such membranes made it possible to reduce the duration of operations and obtain a larger volume of bone regenerate. Barrier membranes made of cross-linked collagen with a long resorption time were used as a comparison group.Results. The use of ICTM for alveolar bone reconstruction allowed us to achieve a maximum bone regenerate height of 6.28 mm, while using Lamina collagen membrane – 2.75 mm. The median difference of bone height before and after surgery with ICTM was 3.605 mm, for Lamina – 1.33 mm. The obtained results allowed us to recommend the use of Lamina membrane for restoration of alveolar bone width and/or height within 3 mm. In case of combined defects of alveolar bone width and height of more than 3 mm, we recommend the use of customized 3D printed titanium frame membranes.
