The results of bone grafting using a xenogenic cortical plate BioOst

Abstract

The fundamental condition that determines the effectiveness of treatment, immediate and long-term positive results, is the amount of bone tissue of the jaws in the places of the proposed implantation [1,2,3]. Defects in the dentition of a large extent and severe atrophy of the bone tissue of the jaws due to the loss of teeth significantly limit the use of the method of dental implantation[4,5]. It is reasonable to expand the indications for the use of dental implants in case of atrophy of the jaw bone tissue in the places of their installation allows the optimization of surgical techniques aimed at increasing the volume of the jaw bone tissue, such as the use of new osteoplastic materials for guided bone regeneration [6, 7] Purpose of the Study: the objective is to analyze the results of a jawbone graft using a BiOTECK xenogeneic cortical plate. Research Materials and Methods The test group consists of 22 patients (11 men and 11 women) with jawbone atrophy. All patients underwent a bone graft surgery using a BiOTECK xenogeneic cortical plate (manufactured by BiOTECK, Italy). In the course of the study, all patients with jawbone loss underwent a dynamic clinical and X-ray examination during the following stages: - during the dental implant surgery planning stage aimed at determining the volume of the bone tissue available and identifying the associated conditions and diseases (prior to conducting an osteoplastic procedure); - prior to the installation of dental implants (6 months after the osteoplastic surgery); - prior to the start of the orthopedic stage of treatment (12 months after the osteoplastic surgery). Results The CBCT data were analyzed and statistically processed to obtain the results. It was revealed that the values of the bone densitometry indicator went up 6 months after the bone graft using the BiOTECK xenogeneic cortical plate (manufactured by BiOTECK, Italy), the values of the densitometric density of jaw bone tissue indicator increased. Immediately after the bone graft using the BiOTECK xenogeneic cortical plate (manufactured by BiOTECK, Italy), the thickness of the bone tissue of the upper jaw was increased by an average of 5.0 0.1 mm. The thickness of the bone tissue of the lower jaw was increased by an average of 3.9 0.1 mm. By the time of the first stage of the dental implant surgery (6 months after the osteoplastic procedure), due to the observed resorption, the thickness of the bone tissue of the alveolar process of the upper jaw decreased by 1.1 0.1 mm and amounted to 6.8 0.1 mm (bone resorption rate was 13.9%), the thickness of the bone tissue of the alveolar process of the lower jaw decreased by 0.80.2 mm and amounted to 6.60.3 mm (bone resorption rate was 10.3%). Conclusion The clinical and X-ray results obtained 1 year after installing dental implants and performing the bone graft surgery using the BiOTECK xenogeneic cortical plate indicate a stable volume of marginal bone tissue in the area of the alveolar crest reconstruction.
