ABSTRACT

Aim: To compare the effectiveness of conventional/delayed loading (group I), early loading (group II) and immediate non occlusal loading (group III) of single implants by assessing peri-implant marginal bone level, width of attached gingiva and probing depth. Material and method: Thirty patients requiring single tooth replacement were selected from the OPD of Department of Prosthodontics & Crown and Bridge. In group I, 10 implants were placed at healed sites following standard two stage procedure of implant placement. In group II, 10 implants were placed at healed sites following which a healing abutment was placed at stage I surgery. Following which a definitive restoration was placed on definitive abutment 3 weeks after surgery. In group III, 10 implants were placed at healed sites following which a definitive abutment was placed at stage I surgery. The crestal bone was evaluated around the definitive abutment after placement of provisional/definitive restoration, at baseline (after loading) and 6 months using CBCT. Results: In group I the change in mean crestal bone level change from baseline to 6 months on buccal, lingual, mesial and distal sites were 0.47±0.14mm, 0.49±0.15mm, 0.49±0.14mm and 0.49±0.14mm respectively, in group II 0.50±0.09mm, 0.43±0.07mm, 0.45±0.08mm and 0.44±0.06mm respectively and in group III 0.43±0.08mm, 0.43±0.06mm, 0.39±0.06mm and 0.46±0.08mm respectively. Conclusion: The results are conclusive of the fact that the placement of definitive abutment at stage I surgery i.e. immediate loading results in a lesser vertical bone loss around implants followed by early loading and then by delayed loading.
