Background: Apart from high demand of dental implants among patients, there are many related factors affecting success of dental implants. The present study was conducted to assess complications associated with dental implants. Materials & Methods: This retrospective study was conducted on 180 dental implants inserted in 112 patients. In all patients, complications such as fracture of implant, loosening of screw, peri- implantitis, fracture of prosthetic part, mucocitis and ulcers were recorded. Results: Out of 112 patients, males were 68 in which 102 dental implants and females were 44 in which 78 dental implants were inserted. The difference was non- significant (P> 0.05). Out of 68 males, 12 and out of 44 females, 7 had complications. The difference was significant (P< 0.05). Common complications were fracture of implant in males (2) and females (1), loosening of screws in male (1) and female (1), peri- implantitis in males (3) and females (2), prosthetic part fracture in males (1) and females (1), mucocitis in males (4) and ulcers in male (1) and females (1). The difference was non- significant (P> 0.05). Conclusion: Complications in dental implants are not uncommon. Mostly fracture of implant, loosening of screw, peri- implantitis, fracture of prosthetic part, mucocitis and ulcers are found.
