Current trends in implantology aim to reduce loading delay but not necessarily with osseo-integration. Procedures may be optimized in post-extraction implantation with immediate loading. Consequently, a transitional denture is not required and esthetics is improved. The psycho-social aspect improves and healing time is reduced, and thus, the neuro-physiological integration of the prostheses is facilitated.
Current literature reports similar success ratios when comparing immediate and delayed loading, but it only concerns rehabilitation of complete edentulous subjects. With this procedure, no post-extraction implantation study has been referenced. Immediate loading in post-extraction implantation also presents some disadvantages due to extreme anatomical and clinical variability. Consequently, this type of procedure requires an experienced practitioner. The lack of data may be explained by the lack of reproducibility of this procedure and the increased number of implants necessary as compared to the conventional procedures. Literature analysis reveals that the observation period of the studies was a maximum of 60 months. This relatively short period may not allow for validity, as the result criteria were implant durability and absence of complications. The implant’s bio-physiological state and surrounding tissue were rarely considered. An interesting alternative to this evaluation methodology uses the Misch criteria. Implant success is determined not only by its duration but also according to the evaluation of the surrounding periodontal tissue.
