Abstract
INTRODUCTION
The state of dental implantation is characterized by high efficiency and a significant spectrum of possibilities when replacing dentition defects. At the same time, prevention of complications of dental implantation associated with the loss of bone tissue around dental implants is of great importance are gaining. It leads to a reduction of both the durability and the period of use of orthopaedic structures supported by dental implants. The aim of the study was to increase the effectiveness of orthopaedic treatment of patients with bounded edentulous spaces with the help of non-removable denture structures supported by dental implants.
MATERIAL AND METHODS
49 patients aged 30 to 44 years with bounded edentulous space in the upper jaw were examined using clinical (examination, palpation, percussion) and special (computed tomography, resonance-frequency analysis of implant stability) diagnostic methods. Patients were placed 68 dental implants. After 6 months of the osseointegration period, all patients were divided into two groups according to the choice of loading protocol by permanent orthopaedic structures.
RESULTS
Six months after the implants were placed, bone loss was observed in patients from both study groups at the level of 0.823 ± 0.029 mm and 0.612 ± 0.022 mm. The greatest changes regarding the stability of dental implants were noted in patients of both groups in a year. Thus, in group I, where patients had metal ceramic crowns, 6 months after implantation a statistically significant loss of bone tissue (1.297 ± 0.049 mm) was noted. The maximum value reached 1.8 mm. And in group II, where orthopaedic treatment was performed by gradually increasing the occlusal load on the dental implant, a statistically significant (p <0.05) increase in the investigated index (0.651 ± 0.038) was not observed.
CONCLUSIONS
The gradual load on the dental implant, in conditions of insufficient bone mineral density, helps to maintain a constant amount of bone around it and prolong the life of the orthopedic structure in general.
