[Effect of dental implants with conditioned surface based on sodium hydroxide in patients with osteoporosis]. / Otsenka éffektivnosti primeneniia dental'nykh implantatov s konditsionirovannoi poverkhnost'iu na osnove gidroksida natriia u patsientov s osteoporozom.

The problem of improving the efficiency of implantological treatment of patients with osteoporosis (OP) today remains relevant due to the high frequency of postoperative complications. Among the main factors affecting the success of dental implant treatment, the nature of the implant surface is essential. Patients with adentia and OP especially relevant in use of dental implants with optimized surface, air conditioned component influencing bone remodelling. OBJECTIVE: Evaluation of the effectiveness of dental implants with a conditioned surface based on sodium hydroxide in men with osteoporosis. MATERIAL AND METHODS: The study included 60 men 54-65 years of age in need of dental implants of which 40 were diagnosed with OP. Patients with OP were divided into groups: I - 20 men without antiresorptive therapy; II - 20 men taking ibandronate 150 mg monthly, calcium and vitamin D (1000 mg/800 IU daily). The control group consisted of 20 men 54-65 years without OP. Microarchitectonics of the mandible was studied using cone-beam computed tomography and histomorphometry. Implants with bioactive surface based on sodium hydroxide (NaOH) were used. RESULTS: The results showed that the success of osseointegration is due to the qualitative parameters of the bone tissue of the perceived bed and the initial level of remodeling processes and does not depend on the conditioning of the implant surface NaOH. Comprehensive antiosteoporotic therapy with bisphosphonates and calcium supplementation with vitamin D leads to restoration of micro-alveolar part.

[Features of restoration of chewing efficiency in patients over 50 years with complete absence of teeth and alveolar bone atrophy.]

The base of osteoporosis is an imbalance of bone remodeling processes, with a predominance of the resorption phase that in the maxillofacial region is manifested by a partial and complete absence of teeth with a decrease in the volume of bone tissue of the jaws and a violation of its microarchitectonics. Atrophy of the alveolar bone reduces the degree of fixation of the removable prosthesis, can develop various diseases of the underlying mucosa. In this regard, the installation of dental implants as a support for removable orthopedic structures is relevant, however, in patients with osteoporosis, the risk of complications in the early and late postoperative period remains high to 44%. Objective: to improve the efficiency of dental implantation in patients with osteoporosis. 80 men over 50 years old with complete absence of teeth on the lower jaw with alveolar atrophy and osteoporosis were under observation. Carried out condition monitoring of the micro alveolar bone in patients with osteoporosis without a comprehensive antiosteoporotic therapy and in patients receiving ibandronate for 1 tablet (150 mg), 1 time a month with calcium 1 000 mg and vitamin D (cholecalciferol) 800 IU daily. It was found that taking antiresorptive therapy for 3 months improves the quality of the alveolar bone, increases the effectiveness of dental implantation in patients with complete absence of teeth and atrophy of the alveolar part.
