Comparative assessment of crestal bone level around non-hydrophilic and hydrophilic implants after immediate...

Immediate implant placement requires early healing and preservation of crestal bone; however, limited evidence exists regarding the comparative effect of hydrophilic implant surfaces on early bone healing and crestal bone level changes. Therefore, it is of interest to evaluate crestal bone level changes around hydrophilic and non-hydrophilic dental implants placed in immediate extraction sites. Hence, a total of 30 implants were allocated into two groups. Following atraumatic extraction, implants were placed, and crestal bone levels were assessed at baseline, 1, 3, and 6 months. The hydrophilic group demonstrated greater early bone-forming activity with reduced crestal bone changes at 1 month compared to the non-hydrophilic group. However, no statistically significant difference was observed between the groups at 3 and 6 months. Hydrophilic implants may therefore enhance early crestal bone formation in immediate extraction cases.
