[Reparative potential of bone tissue and associated influencing factors]. / Reparativnyi potentsial kostnoi tkani i vliyayushchie na nego faktory.

OBJECTIVE: The aim of the sthudy. To study the influence of general and local factors on the regenerative potential of bone tissue to optimize augmentation mechanisms in the treatment of jaw atrophy. MATERIALS AND METHODS: The influence of general and local factors on the regenerative potential of the bone during the augmentation operation of the alveolar process (part) of the jaw in 68 patients was studied. The survival rate of dental implants and the incidence of complications after completion of dental rehabilitation in the long-term follow-up period (more than 5 years) were evaluated. 18 indicators were studied, which were evaluated by qualitative and quantitative methods. The study of the effect of indicators on regeneration was carried out using an accurate Fischer test for conjugacy tables. The assessment of the strength of the influence was calculated as the ratio of the chances of developing an unfavorable outcome of bone grafting and dental implantation. RESULTS: He highest chances of developing adverse outcomes were found in smoking patients with diabetes mellitus, high body mass index, low survival of bone walls, severe bone atrophy (5.6 and higher class according to Cawood & Howell), three-dimensional bone defect, in the absence of 3 or more bone walls, the presence of subcompensated and decompensated psychological state the patient. In the course of histological examination, the influence of these factors on the mechanisms of reparative osteogenesis morphologically manifested a lower degree of progress of regenerative processes and a lower degree of maturity of bone tissue. CONCLUSION: To reduce the chances of developing an unfavorable outcome, in the presence of negative general and local factors, it is not advisable to use dental implantation simultaneously with bone augmentation procedures. In order to reduce the pathophysiological impact of negative factors during sinus lifting, increase the proportion of autosteal material for potentiating the metabolic activity of bone tissue, as well as prescribe antioxidant, antihypoxant and membrane stabilizing therapy before surgery and in the early postoperative period.

Carboxytherapy for the elimination of pain symptoms (or arthralgia) among the elderly persons with the pathology of the temporomandibular joint.

Temporomandibular arthralgia is difficult to treat, painful and often relapses. 48 patients (19 men and 29 women) aged 61-72 years, suffering from the syndrome of pain dysfunction of the temporomandibular joint, were under observation. In 1st (control) group of patients (18 people), NSAIDs indomethacin in tablet form of 25 mg 3 times a day were used for 9 days. In patients of the 2nd (main) group (30 people), the method of invasive carboxytherapy was used, consisting in subcutaneous injection of carbon dioxide with a volume of 3 ml of 5 procedures every other day. On the 3rd, 9th and 15th days of follow-up, invasive carboxytherapy was more effective than the use of a nonsteroidal anti-inflammatory agent by 8.9; 36,5 and 37%, respectively. The high efficiency of the method of invasive carboxytherapy for the elimination of pain symptoms in pain dysfunction was shown, which was 22,86% on day 3; 64,29% on day 9 and 68,16% on day 15 of observation. The method of invasive carboxytherapy can be used in the complex treatment of patients with pain dysfunction of the temporomandibular joint.

[Age-related and post-extraction atrophy of the jaws and modern possibilities for restoring the masticatory apparatus in the elderly people.]

The data of clinical examination of 3 329 people (1 760 men and 1 569 women) living in various regions of the Russian Federation (St. Petersburg and Leningrad region, Moscow and Moscow region, Krasnodar Territory) are presented. The aim of the investigation was to study the frequency of tooth loss and clinical manifestations of atrophy of the alveolar processes (parts) of the jaws in patients of older age groups to assess the possibility of dental rehabilitation using orthopedic structures on dental implants. The study of the prevalence and degree of atrophy showed that in the older age group, patients of senile age were more dominated by 4 and 5 degrees of atrophy, the frequency of their occurrence was about 20-30%. The incidence of grade 6 atrophy was also higher than in other age groups, it was found in 17,22% of men and 17,81% of women in the upper jaw and 22,18% and 15,79% in the lower jaw, respectively. Despite the fact that the number of patients in older age groups with complete or partial loss of teeth does not tend to decrease, at the present stage of development of dentistry and dental implantology, the possibility of restoring the integrity of the masticatory apparatus with the use of artificial supports is possible in virtually all clinical cases. The presence of comorbid or multimorbid pathology is not an absolute contraindication, but is only a temporary factor that postpones dental rehabilitation until the general somatic status of the patient is stabilized.

[Features of clinical flow of odontogenic periostitis of maxilla and jaw in the people of different age].

This article presents the results of medical reports retrospective analysis of 605 patients that came to multisectoral maxillofacial hospital with acute odontogenic periostitis of maxilla and jaw by emergency or according to urgent indications in 2008-2011. The age-related features of prevalence and principal reasons of development and clinical aspects of localization of odontogenic periostitis of maxilla and jaw within the people of different age are shown.
