“…In a clinical study with bone graft in the maxilla, Rasmusson et al (13) reported an increase in ISQ values along the time, and recommended the use of small diameter drills for implant insertion, in order to generate high compression forces that allow higher stability, at least initially. Similarly, Glauser et al (14), in a study using RFA in 81 dental implants for a year, observed a continuous decrease of implant stability that finally failed. They concluded that low ISQ values after 1 to 2 months seem to indicate a higher risk for a future implant failure.…”

Background: Dental primary implant stability is considered essential in the success of the osseointegration process. The recent advent of the resonance frequency analysis (RFA) seems to effectively measure primary implant stability, although its relationship with implant survival has to be further established. Patients and Methods: Seventy patients with complete mandibular edentulism underwent dental implant rehabilitation by means of the placement of 68 dental implants within the interforaminal region and subsequent placement of an overdenture. Primary implant stability was measured by means of RFA and it was expressed in terms of imPrimary implant stability was measured by means of RFA and it was expressed in terms of implant stability quotient (ISQ) on the day of the implant insertion and at the time of the healing abutment placement in a conventional implant two-stage surgical procedure. Results: Overall implant survival rate was 97.1% at the end of the follow-up period. The mean ISQ value for 3.75 and 4.25 mm diameter implants was 78.4 ± 5.46 and 80.83 ± 5.35 respectively, at the time of the implant placement; and 76.68 ± 4.34 and 78.22 ± 6.87 respectively, at the second surgical stage. No statistical differences were observed in relation to changes in mean ISQ value along the healing process. Conclusions: No statistical differences in terms of primary and secondary implant stability measured by RFA exists between 3.75 mm and 4.25 mm diameter implants in the conventional implant two-stage surgical procedure in patients with non-atrophied edentulous mandible being restored with an overdenture. Furthermore, no statistical association between RFA and the implant insertion torque was observed for endosseous dental implant placement at the first surgical stage.

обзорыДентальная имплантация по праву имеет одно из ве-дущих мест среди методов лечения стоматологических забо-леваний. Велика ее роль в восстановлении качества жизни пациентов. Все шире и смелее в амбулаторной практике при-меняются реконструктивно-восстановительные операции на альвеолярных отростках челюстей и верхнечелюстной пазухе. Лавинообразно растет количество устанавливаемых стомато-логами дентальных имплантатов, расширяются показания к дентальной имплантации [1].Современное состояние имплантологии характеризуется различным уровнем решения клинических задач по восста-новлению утраченных зубов с помощью имплантатов. Дис-куссионным остается вопрос о сроках начала протезирования после непосредственной имплантации [1,2].Главное условие достижения остеоинтеграции -тесный контакт между костным ложем и поверхностью имплантата непосредственно в момент оперативного вмешательства [3]. Поэтому на хирургическом этапе имплантации необходимо учитывать плотность костной ткани и первичную стабиль-ность имплантата.Для измерения плотности костной ткани шире всего применяется рентгеновская денситометрия, позволяющая объективно оценить состояние кости до имплантации; изме-рив плотность костной ткани в области прогнозируемой уста-новки ДИ, можно предупредить отдаленные осложнения, определить сроки проведения дальнейших этапов восстанов-ления жевательной функции и при благополучных показате-лях -сократить их.Стабильностью считают способность системы функцио-нировать, не изменяя собственную структуру, и находиться в равновесии. В дентальной имплантологии используют поня-тие первичной и вторичной стабильности. Контакт между костью и имплантатом обеспечивает первичную, или механи-Тел.: +7 (926)

The goal of an implant supported reconstruction is to obtain optimal aesthetics and function. In order to achieve this, visualisation of the final restorative reconstruction is necessary prior to beginning treatment. The term 'restorative-driven' treatment planning has been used to identify this process. 1 It requires a team approach of specialists, who can develop a multidisciplinary treatment plan. It starts with an accurate diagnosis, which will lead to a prognosis of each individual tooth and the overall dentition. This information will help the clinician develop the treatment options suitable for tooth replacement. Only when the goals have been defined can the sequence of therapy be established. Working backwards from the wax-up of the final diagnostic model of the proposed treatment assists not only with the management of the complex case, but will help avoid mishaps. 2 Effective communication between the team and the patient is extremely important. Understanding the patient's expectations is key to a successful outcome. Deciding that these expectations are realistic requires a correct diagnosis and an inter-disciplinary treatment plan that is logical. This approach takes time and requires a comprehensive treatment discussion between the team members, and then a thorough case presentation to the patient. 3 Only then will the patient begin to understand the extent of their problem and the options available to reconstruct their mouth.
