简要总结
Two different drilling techniques in posterior maxilla immediate loading implant
详细描述
One of the surgical techniques used to enhance the primary stability of implant in low density bone was the undersized drilling technique, which has been introduced to locally optimize poor density of bone by using a final drill diameter considerably smaller compared with the implant diameter.
On the other hand, a novel hollow drill with a single drilling systems was designed. Single drilling technique shortens surgical times, removes the smallest amount of bone during implant site preparation, reduces bone damage and micro fractures, and speeds up the healing process. Additionally, because of the hollow shape, bone core may be harvested and used as an autogenous bone grafting material.

结局指标
主要结局
Implant stability
时间窗: 12 months
Implant stability will be assessed at the time of implant insertion and at 3, 6 and 12 months after surgery.
Modified Sulcus Bleeding Index (mBI)
时间窗: 12 months
It will be measured at 3,6 and 12 months post-operatively. Clinical signs and symptoms of inflammation of peri-implant mucosa will be graded using criteria of modified sulcus bleeding index (mBI).
Peri-implant probing depth
时间窗: 12 months
Depth of the peri-implant sulcus will be recorded initially at the time of loading, 3, 6 and 12 months following implant loading by a graduated periodontal probe with light force to avoid undue tissue damage and over-extension into the healthy tissue
Marginal Bone Loss
时间窗: 12 months
For the calculation of marginal bone loss (MBL), the implant will be used as a reference by adjusting the cross-sectional and panoramic long axis in the center of the implant and bisecting it
Bone Density Recordings
时间窗: 12 months
Relative bone density records will be collected from the bucco-palatal view of the cross-sectional plane using the greyscale bone measuring tool
