Objective: To determine factors affecting dental implant failure in patients reporting to Periodontology department Khyber College of Dentistry, Peshawar.

Material and methods: This retrospective study was conducted on 50 consecutive cases having failed implants. Inclusion criteria were cases having age from 30 to 70 years, both gender and Pakistani nationals. Patients suffering from endocrine problems, chronic infectious disorders, periodontitis, using immunosuppressive drugs and pregnant females were excluded from study. Data like age, implant length, diameter and bone quality were recorded. The data were entered and analyzed in SPSS version 22. Descriptive statistics like mean and SD was calculated for continuous data and frequency and percentages were calculated for categorical variables. Factors for implant’s failure were stratified by gender using Chi-square test. P≤0.05 was considered significant.

Results: The males were 29(58%) and females were 21(42%). The mean age was 51.3±9.73 years. The most common site of failure was maxillary posterior (n=18, 36%) followed by mandibular posterior (n=13, 26%) then by maxillary anterior (n=12, 24%). Most failure was seen in implants having length less than 10mm (n=24, 48%) followed by >11.5mm (n=17, 34%). The most failed implants were <3.5mm diameter (n=22, 44%) followed by >4.5mm (n=17, 34%). The common age in which implant failure was seen was above 50 years (n=23, 46%).

Conclusion: Most common factors for implant failure were posterior maxillary area, shorter length, thin diameter and increasing age.
