Abstract

Background: Dental implants have become the standard of care for the replacement of missing teeth, offering high success rates and long-term functional and aesthetic outcomes. Despite advancements, implant failures still occur due to infection, mechanical complications, or inadequate osseointegration, raising concerns regarding the feasibility of re-implantation into previously failed sites. Understanding the differences in survival outcomes between implants placed in failed sockets and those in fresh bone is critical for optimizing patient management and improving prognosis.


Objective: This study aimed to compare the survival rates of implants placed in previously failed implant sockets with those placed in fresh, undisturbed bone sites.


Materials and Methods: This prospective study was conducted at [Hospital Name & Department] between [Date] and [Date]. A total of 63 systemically healthy patients aged 18–65 years were enrolled and divided into two groups: Group A (31 patients) received implants in previously failed sockets after 8–12 weeks of healing and necessary debridement or augmentation; Group B (32 patients) received implants in fresh bone without prior site compromise. Standard screw-type implants with lengths of 10–13 mm and diameters of 3.5–4.5 mm were utilized. Postoperative follow-up included clinical assessments and radiographic evaluations over 24 months. Smokers, poorly controlled diabetics, and individuals with other systemic risks were excluded.


Results: The mean age of the participants was 43.8 ± 9.1 years. Group A had a slightly higher mean age (45.2 ± 8.7 years) compared to Group B (42.5 ± 9.4 years). Male participants comprised 58.7% (n=37) of the study population. Implant failure rates were higher in Group A at 19.4% compared to 9.4% in Group B. The overall implant success rate was 85.7%. Bone augmentation was required more frequently in Group A (70.9%) than in Group B (25.0%). Smoking and diabetes were significant risk factors for implant failure, with smokers representing 100% of the failed cases (p<0.01) and controlled diabetics showing a 66.7% failure rate (p=0.02).


Conclusion: Implant survival was higher in fresh bone compared to previously failed implant sockets, although both approaches showed acceptable clinical outcomes. Smoking, diabetes, and the need for bone augmentation significantly compromised implant success, emphasizing the necessity for rigorous preoperative assessment and individualized patient management.
