[The results of increasing the thickness of soft tissues after using collagen matrices and connective tissue grafts].

The Study Aims: To evaluate and compare the growth of gingiva around dental implants following the use of collagen matrices and connective tissue grafts (CTG).

Materials And Methods: The study included 80 study participants, who were divided into four groups based on the type of material used to enhance gingival thickness. Two groups utilized collagen matrices, Fibro-Gide and FibroMatrix as materials, while the other two groups utilized CTG obtained from the hard palate or tubercle area of the maxilla as controls.

[Measuring methods of volumetric changes of soft tissues at dental implants site and tooth recessions site].

The article is a review of literature on various methods for measuring gingival thickness at implant site and tooth recession. The purpose of the study was to analyze existing methods for assessing volumetric changes in soft tissues based on literature data and give recommendations on the choice of methods. The authors analyzed available methods and identified limitations and recommendations for the use of different methods.

[Relative survival and cell adhesion of multipotent mesenchymal cells from primary teeth pulp on the surface membranes and sponges produced from collagen].

Objective: To study the behavior of SHED cell culture on different types of materials for the regeneration of periodontal tissues with different porosity.

Material And Methods: Porous collagen material Fibro-Gide (Geitstlich Pharma AG, Switzerland), designed to increase the volume of the gum and the barrier collagen membrane Bio-Gide (Geitstlich Pharma AG, Switzerland) were studied on SHED cultures. As a control sample, a Spongostan sponge made of gelatin (Johnson & Johnson Medical, UK) with the most pronounced porosity and wettability was used.

USE OF VOLUME-STABLE COLLAGEN MATRIX FOR SOFT TISSUE AUGMENTATION AT TEETH AND DENTAL IMPLANTS SITE.

The aim of this clinical report is to demonstrate the capabilities and the results of a porcine collagen matrix application to increase the soft tissue volume in the area of placed implant at 3.1 site and of implant-supported cantilever prosthesis at 3.2 site.
