Clinical evidence and Science 39 Within a study performed by Edinger et al. (2021) the impression was taken at the time of implant placement and after a submerged healing of two to three months the definitive crown bonded to a titanium base was placed at the second stage surgery (9). Three different implant brands (CAMLOG® SCREWLINE (61%), Straumann, Thommen) were included in this retrospective study. The outcome focused on the pink esthetic score including formation of papillae and the patient satisfaction with the treatment. The efficient procedure with only three treatment sessions to finally restore the gap and the good adaption of the mucosa to the final restoration led to a very high acceptance and satisfaction rate by the patients after three years of follow-up. Early loading in aesthetic zone In the anterior maxillary region, the patients have a need for early functional and aesthetical solutions. Kahramanoglu et al. (2019) provisionally restored CAMLOG® implants in the anterior region up to the first premolar after a healing time of three weeks. This was then exchanged to the final restoration after eight weeks (10). The clinical and radiological evaluation parameters were collected at yearly follow-ups until three years post implant placement. The early loading concept in the aesthetic zone with single tooth restorations showed promising results with only minor bone loss of 0.47 ± 0.75 mm and a survival rate of 100%. The early functional loading had also no negative effect on the soft tissue stability. KEY TAKE OUTS: LOADING PROTOCOLS Following an appropriate treatment protocol with adequate implant stability immediate loading, early loading as well as conventional delayed loading led to success of the implant restorations from the point of view of hard and soft tissue integration. The possibility of immediacy has positive side- effects like shortened treatment duration, improved aesthetics, and high patient acceptance.
