Peri-implant Bone Behaviour Using Two Drilling Techniques in Posterior Maxilla

Not Applicable

Completed

• Conditions: Implant

• Registration Number: NCT06770231
• Lead Sponsor: Mansoura University

Brief Summary

Two different drilling techniques in posterior maxilla immediate loading implant

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Implant stability	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)	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	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	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	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
