“…Temperature rise during sustained drilling could be explicated by lack of cooling fluid in the deep part of the osteotomy and the blockage caused by bone residue on the drill's cutting edge. Using slower speeds exaggerates this blockage and reduces the drill's cutting efficiency, resulting in more time required to prepare the bone bed and further heat generation (38), which in turn affects the bone tissue viability as proposed in the current study.…”

BACKGROUND: Viability of the harvested bone during osteotomy preparation is affected by the generated heat, which in turn is related to drilling speed and time; this bone viability is considered an indicator of the quality of the harvested autograft. STUDY OBJECTIVE:The aim of this study was to assess the effect of two different drilling speeds on bone cell viability of bone harvested during osteotomy preparation. MATERIALS AND METHODS:A split mouth randomized controlled clinical trial was carried out on 8 patients, 16 mandibular premolar /molar edentulous ridge sites, using a trephine bur, 8 osteotomies were drilled using a speed of 1000 rpm (Control Group) and the other 8 using 400 rpm (Test Group), implants were placed, the harvested bone viability was evaluated histologically in both groups. RESULTS:The histological assessment revealed better viability features in samples harvested using 1000 rpm (Control Group). CONCLUSION: Drilling at 1000 rpm seems to yield stronger autologous bone viability than drilling at 400 rpm.

“…The presence of sufficient primary stability of the implant, along with other factors such as minimally traumatic surgical technique (14)(15)(16)(17) and the macro-and micro-geometry of the fixture (18)(19)(20) , has been considered as critical factor in achieving and maintaining implant osseointegration. However, it is more difficult to define and control the various variables that influence the achievement of sufficient primary stability.…”

Objectives: The present study evaluated the effect of different insertion torque types on stability of tapered implants with knife-edge thread design. Subjects and methods: Twenty four Patients were randomly assigned into three groups according to the peak torque value recorded during implant insertion: Group 1: low torque application (<30 N/cm). Group 2: medium torque application (30< IT <50 N/cm). Group 3: high torque application (>50N/cm). Dental implants were evaluated clinically and radiographically. (IT) and (ISQ) values were recorded during implant insertion for each group. ISQ values were recorded also at 3 and 6 months. Crestal bone level were recorded using RVG at baseline, 3months and 6months. Bone density were recorded by CBCT at baseline and at 6 months after surgery. Results: There was a positive correlation between Overall Torque and stability after 3 and 6 months. A general linear relationship between insertion torque and implant stability. High Torque group showed the higher crestal bone loss and bone density than the other groups. Conclusion: Knife edge threaded design implant showed a satisfactory stability including implants inserted with low torque. High torque group showed the highest stability and increasing in bone density, but also it showed the highest crestal bone loss.

Purpose. Various parameters can influence temperature rise and detection during implant site preparation. The aim of this study is to investigate local temperature values in cortical and corticocancellous bovine bone during early stages of piezoelectric implant site preparation. Materials and Methods. 20 osteotomies were performed using a diamond tip (IM1s, Mectron Medical Technology, Carasco, Italy) on two different types of bovine bone samples, cortical and corticocancellous, respectively. A standardized protocol was designed to provide constant working conditions. Temperatures were measured in real time at a fixed position by a fiber optic thermometer. Results. Significantly higher drilling time (154.90 sec versus 99.00 sec; p < 0.0001) and temperatures (39.26°C versus 34.73°C; p = 0.043) were observed in the cortical group compared to the corticocancellous group. A remarkable variability of results characterized the corticocancellous blocks as compared to the blocks of pure cortical bone. Conclusion. Bone samples can influence heat generation during in vitro implant site preparation. When compared to cortical bone, corticocancellous samples present more variability in temperature values. Even controlling most experimental factors, the impact of bone samples still remains one of the main causes of temperature variability.
