EXPERIMENTAL ASSESSMENT OF THE BONE CAVITY HEATING AT DIFFERENT SPEEDS DURING PREPARATION FOR DENTAL IMPLANTATION

The objective of the study was to evaluate level bone tissue heating experimentally during various high-speed and slow-speed protocols for preparation cavity dental implantation. Materials Methods: 8 samples skeletonized veal ribs (length 10.00–12.00 cm thickness 1.50–2.00 cm) were dissected, four cuts made according different speed at a distance 1.00–1.50 from each other. duration manipulation 15 s. Lindemann guide drill with diameter 2.20 mm (apex – 1.70 mm) length 35.00 (with limiter) used work without any cooling operating field. following parameters applied: 1000 rpm, 300 100 50 rpm; in all cases, torque surgical 35 N×cm. Bone temperature measured an electronic contact thermometer before immediately after manipulation. Results: Measurements showed that observed almost applied preparation. This fact can represent danger patient by increasing risk developing localized osteomyelitis alveolar ridge due trauma. This, turn, increase installed implant disintegration or development fiber integration. During seconds heated up most; average 5.64 ± 2.23 °С (М = 4.60 °С), value 3.00 10.30 °С. At less 3.79 1.76 °C (M 3.80 °C), values range 1.10–6.40 °C. canal 2.99 1.36 2.65 within 1.10–5.20 minimal 2.06 0.66 1.95 recorded 1.00–3.20 Considering most experimental studies, time (or its model) longer 1 min, while our such prolongation interaction impractical (the fully prepared s) cutter surrounding minimized, decision create mathematical regression model thermal reaction treatment. application created min use drills rpm N×cm could lead critical 62.50% 50.00% 25.00%. water did not impose tissue. Conclusions: data on when using speeds field obtained. safest method scheme
