NCT03674762

Brief Summary

Aim: to evaluate and compare radiographic marginal bone loss (MBL) and soft tissue parameters around submerged/two-stage and nonsubmerged/one-stage single implants with same tapered body design and surface, same thread design and distance, and same collar surface (laser-microgrooved), after 3 years of loading.

SEQUENTIAL
Model Details: The cases were randomly divided into two groups as two-stage/submerged, and one-stage/nonsubmerged. Thus, in each patient, the two implants (submerged and nonsubmerged) were placed randomly in the left and right hemi-mandible or in the left and right hemi-maxilla
