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.

Inclusion criteria

1. Patients with missing single or multiple teeth in posterior maxilla. 2. Age more than 18 years. 3. 10 mm or more vertical bone height is present. 4. Good oral hygiene. 5. Patients willing to be present during the study follow up intervals. 6. Patients free from any systemic diseases. 7. 6 mm or more ridge width is present. 8. Crown height space of at least 8 mm. 9. Patients without any para-functional habits (bruxism and clenching).

Exclusion criteria

1. Patients with any pathological lesion or root tips at the planned surgical site. 2. Patients with inadequate bone height and thickness. 3. Smoking more than 14 cigarettes per day.14 4. Alcohol or drug abuse. 5. Patients with systemic diseases that absolutely contraindicate implant placement.

Design outcomes

Primary

MeasureTime frameDescription
Implant stability12 monthsImplant 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 monthsIt 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 depth12 monthsDepth 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 Loss12 monthsFor 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 Recordings12 monthsRelative bone density records will be collected from the bucco-palatal view of the cross-sectional plane using the greyscale bone measuring tool
