Effect of Loading Protocol on Peri-implant Soft Tissue Health (Clinical study)

Abstract

This clinical study evaluated the effect of type of loading on per-implant soft tissue health . Material & Methods: • 30 Implants were placed in upper premolar area using surgical guide and divided randomly according to the loading protocol. In the same day of the surgery, the final impression was taken. Patients in the control group (INFLP) received CAD/CAM PMMA (out of occlusion for 3 months). After 3 months the crown was replaced by CAD/CAM VITA ENAMIC crown (functional loading). • Patients in the other 2 study groups: group (IFLV) received CAD/CAM VITA ENAMIC crown (immediate functional loading).The occlusal parameters during the CAD procedure were adjusted to establish a light occlusal contact in centric occlusion. After the milling procedure, final adjustments of the crowns were performed inside the patient’s mouth with 200 micron articulating paper to establish a light contact in centric occlusion and ensure canine guidance in lateral excursive movements. • The other group (IFLP) received CAD/CAM PMMA crown (in occlusion for 3 months) followed by CAD/CAM VITA ENAMIC crown.
