Healing After Augmentation of Alveolar Ridge Using Collagen Membrane

Overview

One of the prerequisites for successful prosthetic implant therapy of patients is achieving the initial stability of the embedded implant, which largely depends on the width alveolar ridge, at the place of its installation. Regenerative therapy of the horizontal dimension of the alveolar ridge simultaneously with the installation of implants is carried out using biocompatible materials; a basket of thin ones substitutes and collagen membranes. Clinical application of the collagen matrix to date has shown successful regeneration soft tissue in corrective surgery of the oral mucosa, by increasing the volume of the gingiva, approximately as effective as the application of a connective tissue graft from the palate. In the current literature, there is no data on the cellular effects of the regeneration of soft, a especially bone tissue, after the application of a membrane with cross-linked collagen type I, u regenerative therapy of fenestrations, dehiscence and buccal contour augmentations bone lamellae, simultaneously with implant placement. Also, tissue monitoring mechanisms of regeneration of soft and bone tissue, has not been shown in the literature so far controlled and systematized results using the Primescan digital program scans and software analysis of soft tissue regeneration parameters, as well as their own correlations with CBCT and clinical analysis.

The physiological process of bone tissue resorption after tooth extraction results in significant by changing the initial dimension of the alveolar ridge, due to horizontal and vertical resorption of bone tissue.this process is monitored and by a significant reduction in the volume of soft tissue and the width of the keratinized gingiva.Successful implant therapy is considered when the initial stability is achived of the embedded implant, which largely depends on the width alveolar ridge, at the place of its installation. However, despite achieving the initial stability, inadequate width of the alveolar ridge, and what according to the surgical protocol is a minimum of 1.5 mm. it is the cause of later complications due to present bone resorption processes and peri-implant soft tissue reduction. Regenerative therapy of the horizontal dimension of the alveolar ridge simultaneously with the installation of implants is carried out using biocompatible materials; a basket of thin ones substitutes and collagen membranes. Clinical trials have shown high degree of success of the regenerative therapy of the thinned buccal bone lamella, its deficiencies, as well as occurrences of dehiscence and fenestration, the treatment of which is carried out simultaneously with by inserting an implant. Moreover, simultaneous regenerative therapy of the mentioned bone defects with the installation of implants reduces the risk of buccal bony lamella and soft tissue collapse. Recent review paper and meta-analysis showed complete bony healing of fenestrations and dehiscence regardless of whether a bone substitute with or without collagen is used membrane, which is not the case if the operative region is covered only by mucoperiosteal flap, without regenerative therapy. The primary goal of this research would be to determine the success of regenerative therapy bone and soft tissue from the buccal side.
