The forecasting implant stability quotient (ISQ) coefficient of dental implants in different types of jaw bone

Abstract

We studied the efficiency stability rate of dental implants in different types of bone tissue. 48 patients were examined in clinic and determined the state of the jaw bone tissue with the help of cone-beam computed tomography (CBCT) in «Planmeca Romexis» software. The density of jaw bone tissue evaluated using Hounsfield index to quantify the scale of radiographic bone density. During dental implants placement and 6 months after, prior to orthopedic treatment, implants primary stability ratio was determined using the MEGA-ISQ device (South Korea). Based on studies in 48 patients tested in the field of dental implants installed I type of bone was in 14 patients, Hounsfield value of the index correspond to 1300 units. (M ± m), the implant stability coefficient after 6 months was as high as possible and amounted to 94.0 U.II type of bones noted in 12 patients, Hounsfield value of the index corresponds to 850 units. (M ± m), the coefficient of implant stability after 6 months was 84.0 U. Type III was diagnosed in 12 patients, the value of the Hounsfield index corresponded to 500 units. (M ± m), the coefficient of implant stability after 6 months was 80.0 U.10 patients were with IV type of bone tissue, the Hounsfield index corresponded to 380 units. (M ± m), the stability ratio of the implant during the operation after 6 months amounted to 63.0 U. Measuring the implant stability factor (ISF) gives clinician the opportunity to accurately assess each specific clinical situation as accurately as possible.

Цель исследования включала определение коэффициента стабильности дентальных имплантатов при разных типах костной ткани. В клинике обследовано 48 пациентов, у которых определяли состояние костной ткани челюстей на основании данных конусно-лучевой компьютерной томографии (КЛКТ) в программе «Planmeca Romexis». Плотность костной ткани челюстей оценивали при помощи индекса Хаунсфилда по количественной шкале рентгенологической плотности кости. Во время операции при установке дентальных имплантатов и через 6 месяцев перед проведением ортопедического лечения определяли коэффициент первичной стабильности дентальных имплантатов аппаратом «MEGA-ISQ» (Южная Корея). Измерение коэффициента стабильности имплантата (КСИ) дает клиницисту возможность максимально точно оценить каждую конкретную клиническую ситуацию.
