Abstract

Background: Immediate implant placement to simultaneously replace mono-radicular teeth at the time of extraction has gained wide acceptance as a reliable and predictable treatment option. Application of this option in replacement of molars has presented a difficult challenge both surgically and prosthetically.
Aim of the study: The current study aimed to investigate the efficacy of wide diameter implants in the immediate replacement of mandibular molars over a period of 24 months.
Methods: Thirty implants were utilized in the immediate replacement of mandibular molars in a one stage surgical procedure following the atraumatic extraction of the teeth. The implants were restored after three months and followed-up at 12 and 24 months to evaluate the crestal bone loss around them.
Results: A survival rate of 96.6% was evident at the end of the study period (24 months) with a mean crestal bone loss of 0.33-mm at 12 months and 0.19-mm at 24 months with a total mean crestal bone loss of 0.52-mm during the study period.
Conclusion: Wide diameter implants are a reliable and predictable means to immediately replace mandibular molars with stable long-term prognosis with the consideration of proper extraction procedures and maintenance of the socket architecture.
