Comparison Between Two Placement Concepts of Six Compressive

The aim of this study will be to compare two posterior implant positioning concepts of six compressive implants installed in completely edentulous maxilla and immediately loaded with screw retained prosthesis regarding implant stability and peri-implant tissue health (plaque index ,bleeding index and pocket depth )

Treatment and study plan

Implant

Procedure

six implants will be placed in the maxilla in the following area ( canine , premolar , molar )

Primary outcomes

  1. implant stability

    Time frame: 6 months

    Implant stability will be measured by ISQ using an Ostell device

Secondary outcomes

  1. plaque index

    Time frame: one year

    plaque index will be measured with periodontal probe according to the following score 0; absence plaque , score 1; plaque only detected by a probe passing through the smooth marginal surface of the implant, score 2; plaque can be recognized by naked eye, and score 3; plenty of soft matter.

  2. gingival index

    Time frame: one year

    gingival index and bleeding will be measured using periodontal probe according to the following score ; 0; no bleeding when a periodontal probe is passed along the mucosal margin, 1;isolated bleeding spots visible, 2; blood forms a confluent red line on the mucosal margin, 3;heavy or profuse bleeding

  3. Pocket Depth

    Time frame: one year

    Pocket Depth around implant will be measured by mm using periodontal probe
