No additional bone loss was noted 15 weeks after placement of the laser-microgrooved cylindric definitive abutment. Dense connective tissue was in intimate contact with the laser-microgrooved surface to the point of the soft tissue separation, and clear evidence of the junctional epithelium ending at the coronal-most position of the laser-microgrooved zone was identified.
