 Treatment procedure Each patient will receive 2 screw-type Straumann Institut Straumann AG, Basel, Switzerland standard implants Ø4.1 mm, with SLA surface in the canine region of the mandible with an interconnecting line approaching parallelism with the terminal mandibular hinge axis. The implant lengths will be 10mm and 12mm. The choice of implant length will be dictated by the preoperative radiographic assessment of bone height in the canine region and drilling distance with the principal concern achieving primary stability.
