Background: We compared and clinically evaluated suppuration, bleeding on probing (B.O.P.), adverse effects such as abutment screw loosening, crown loosening, fractured abutment and compared and evaluated radiographically the difference in crestal bone loss after placement of narrow diameter implant (NDI) compared with a regular diameter implant (RDI). Materials and methods: A total of 20 implants were placed (10 implants per group with 16 males and 3 females) under local anaesthesia in subjects requiring placement of mandibular and maxillary implants. Selected groups were grouped on the basis of diameter of implant used. The implants were evaluated for implant suppuration using gloved finger, bleeding on probing using periodontal probe, adverse events or complication like screw loosening, crown loosening , abutment loosening and crestal bone loss measured from the shoulder of implant to the first bone implant contact. Results: The inter-group comparison of implant suppuration, bleeding on probing and adverse events at different time intervals showed that the results for both groups were statistically non-significant (p-value at>0.05). The intra-group comparison of the changes in the crestal bone showed that the bone loss was highly significant on the distal side from 0 to 3 months, 0 to 6 months and 3 to 6 months in regular implants. Conclusion: Within the limitations of this study, it was concluded that the regular diameter implants showed a greater bone loss over a period of 6 months, more in the distal aspect than mesial side compared with narrow diameter implants.
