Abstract
The study compared the esthetic success of immediate flapless implants (ILA) to immediate implants with the need for flap (ILB) and delayed implants (DSL) in single tooth restorations, in the anterior region of the maxilla. Another question was existence of relation between the interproximal crestal bone height and papilla height.
Analysis was done using periodontal sounding and radiographs to find out the relation. From 106 participants, including 21 ILA, 22 ILB and 63 DSL cases, we received highest papillary index score of 2.6 average from group ILA, followed by ILB and DSL, after 3 months of prosthetic loading.
When the distance between the base of the contact point of crowns and height of interproximal bone was less than 5, the papilla was present 100 % of the time, but when the distance increased to 6 and more than 7 mm, the papilla was present only 46.5 and 24 % of the time, respectively
