The Lateral Border of Scapula for Alveolar Ridge Reconstruction: A Prospective Clinical Study.

Purpose: The purpose of this prospective clinical study was to evaluate the efficiency of alveolar ridge reconstruction with the lateral border of scapula (LBS) prior to implant placement and to assess onlay graft retention and bone resorption during a short term of function.

Materials And Methods: A total of 25 partially or fully edentulous patients with severe alveolar bone atrophy received ridge reconstruction with grafts harvested from the LBS. Histologic analysis of bone grafts was performed.

[PERIFOCAL TISSUE REACTIONS TO IMPLANTATION OF THE SAMPLES OF HYDROGEL MATERIAL BASED ON POLYACRYLAMIDE WITH THE ADDITION OF THE CELLULOSE (AN EXPERIMENTAL STUDY)].

Tissue reactions to the grafting of samples of composite hydrogel based on polyacrylamide and cellulose of different origin (plant and bacterial) were studied in 48 laboratory outbred rats and 24 rabbits of chinchilla breed. The observations were carried out on Days 5, 14, 45 and 90 after placement of implants in the muscle, joint cavity, deep defects of the articular cartilage and subchondral bone. The study has revealed no migration and degradation of the samples.

[Morphopathogenesis of the amniotic membrane after its transplantation in the course of experimental conjunctiva plasty].

The paper contains the results of an experimental study of the clinical healing of the standard wound defect in the bulbar conjunctiva of rabbit after conjunctiva-plasty involving the use of the human amnion transplant; there is also a description of a histological study of reparative processes in the adjacent tissues and a description of morphological changes occurring in the transplant during the healing process. The study was made on 14 rabbits (28 eyes). It was established that the wound-surface healing occurs, beneath the amnion transplant, without a pronounced inflammation, scarring or immunologic-rejection reaction; its sequence is typical of inflammation and compensatory processes with the formation, in the outcome, of the conjunctiva coating of the eyeball, whose color and composition are ordinary.
