A randomised clinical trial was carried out in order to determine whether changes in the abutment design result in improved quality of the peri-implant mucosal tissue according to the parameters attachment strength, sotft tissue stability and developmemt, and maintenance of bone levels. Twenty-nine patients were included. They received 2, non-adjacent endosseous implants replacing missing teeth in the aesthetic zone. Subsequently, conventional (control) and experimental abutments (with an additional macro groove of about 0.5 mm in depth ) were placed. After 6 weeks and 1 year the effect of the 2 different abutment designs were measured according to the specified parameters. In addition, patients’ and dentists’ satisfaction concerning the muco-gingival results were compared. It was concluded that the 2 abutments produced no significantly different effect on muco-gingival aesthetics. On the basis of additional comparative research between Caucasian and Indian individuals it was concluded that the gingival biotype could best be determined quantitatively.
