Results of bone grafting using a xenogenic cortical plate BiOTECK

BACKGROUND: The fundamental condition that determines the effectiveness of treatment, with immediate and long-term positive results, is the amount of bone tissue in the jaws at the proposed implantation site. Defects in the dentition to a large extent and severe atrophy of the bone tissue of the jaws due to the loss of teeth significantly limit the use of dental implantation. It is reasonable to expand the indications for the use of dental implants in cases of atrophy of the jaw bone tissue in the installation site. This 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.

AIM: This study aimed to analyze the results of a jawbone graft using a BiOTECK xenogeneic cortical plate.

MATERIALS AND METHODS: The test group consisted of 22 patients (11 men and 11 women) with jawbone atrophy. All patients underwent bone graft surgery using a BiOTECK xenogeneic cortical plate (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 dental implant installation (6 months after osteoplastic surgery), and prior to the start of the orthopedic stage of treatment (12 months after osteoplastic surgery).

RESULTS: The cone beam computed tomography data were analyzed and statistically processed to obtain the results. It was revealed that the values of the “bone densitometry” indicator increased 6 months after the bone graft using the BiOTECK xenogeneic cortical plate, and the values of the “densitometric density of jaw bone tissue” indicator increased.

Immediately after bone grafting using the BiOTECK xenogeneic cortical plate, the thickness of the bone tissue of the upper jaw increased by an average of 5.0±0.1 mm and that of the lower jaw increased by an average of 3.9±0.1 mm. In the first stage of the dental implant surgery (6 months after osteoplastic procedure), due to 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: 13.9%), and the thickness of the bone tissue of the alveolar process of the lower jaw decreased by 0.8±0.2 mm and amounted to 6.6±0.3 mm (bone resorption rate: 10.3%).

CONCLUSION: The clinical and X-ray results obtained 1 year after installing dental implants and performing bone graft surgery using the BiOTECK xenogeneic cortical plate indicate a stable volume of marginal bone tissue in the area of alveolar crest reconstruction.
