INTRODUCTION
Dental implant surgery has revolutionized the field of dentistry by offering a reliable solution for replacing missing teeth and restoring oral function and esthetics. With advancements in implant materials and surgical techniques, dental implants have become the gold standard for tooth replacement, boasting high success rates and long-term stability. However, like any surgical procedure, dental implant surgery is not without risks, and complications can arise during or after the treatment.[1,2,3]
Understanding the nature and frequency of complications associated with dental implant surgery is crucial for ensuring optimal patient outcomes and improving clinical practices. Complications can range from minor issues such as postoperative discomfort and swelling to more serious problems like implant failure, infection, and peri-implantitis. Factors such as patient health status, surgical technique, implant design, and postoperative care can influence the occurrence and severity of these complications.[4,5,6]
Despite the widespread adoption of dental implants, there remains a need for comprehensive assessment and documentation of complications to guide clinicians in risk assessment, treatment planning, and patient management. Retrospective studies play a vital role in evaluating the real-world outcomes of dental implant surgery, providing valuable insights into the safety and efficacy of the procedure. By analyzing a large cohort of patients over a specified period, this research targets to identify common complications, assess their impact on treatment success, and explore strategies for minimizing risks associated with dental implant surgery.
MATERIALS AND METHODS
This retrospective research utilized patient records from a tertiary care center over a defined time frame. Records of patients who underwent dental implant surgery from 2015 to 2020 were reviewed, and data on patient demographics, medical history, surgical procedures, implant characteristics, and postoperative complications were collected and a total of 150 subjects were considered for the research. Complications were categorized based on their nature and severity, including criteria such as infection, implant failure, peri-implantitis, and others. Data analysis was performed to determine the frequency and distribution of complications and potential risk factors associated with their occurrence. Ethical approval was obtained from the institutional review board, and patient confidentiality was strictly maintained throughout the research period. This methodology allowed for a comprehensive assessment of complications in dental implant surgery, providing valuable insights into factors influencing treatment outcomes and areas for improvement in clinical practice.
RESULTS
The most common postoperative complication observed was infection, accounting for 15.3% of cases. This was followed by peri-implantitis (12.0%) and implant failure (8.0%). Prosthetic failure, nerve injury, sinus complications, and other complications were less frequent, each comprising less than 6% of cases. Notably, approximately two-thirds (66.7%) of patients experienced no complications following dental implant surgery [Table 1].
Table 1.
Frequency of postoperative complications
| Complication | Number of Cases | Percentage (%) |
|---|---|---|
| Infection | 23 | 15.3 |
| Implant failure | 12 | 8.0 |
| Peri-implantitis | 18 | 12.0 |
| Prosthetic failure | 8 | 5.3 |
| Nerve injury | 4 | 2.7 |
| Sinus complication | 6 | 4.0 |
| Other | 9 | 6.0 |
| No complications | 100 | 66.7 |
There was a notable trend of decreasing complication rates with increasing age. Infection rates were the highest in the 20–40 years age group (20.7%) and decreased progressively with older age groups. Similarly, implant failure and peri-implantitis rates followed a similar trend, with the highest rates observed in the youngest age group and decreasing with advancing age. The differences in complication rates among age groups were statistically significant (P < 0.05), indicating a potential association between age and postoperative complications in dental implant surgery [Table 2].

Comparison of complications by age group
| Age Group | Infection (%) | Implant Failure (%) | Peri-implantitis (%) |
|---|---|---|---|
| 20-40 years | 12 (20.7) | 5 (8.6) | 8 (13.8) |
| 41-60 years | 7 (12.1) | 3 (5.2) | 6 (10.3) |
| 61-80 years | 4 (6.9) | 4 (6.9) | 4 (6.9) |
| >80 years | 0 (0.0) | 0 (0.0) | 0 (0.0) |

DISCUSSION
The findings of this retrospective research provide valuable insights into the prevalence and distribution of postoperative complications following dental implant surgery. Understanding these complications is crucial for optimizing patient care and improving treatment outcomes.
The high incidence of infection observed in this research underscores the importance of strict adherence to surgical protocols and comprehensive perioperative care. Infection prevention strategies, such as preoperative antimicrobial therapy and meticulous surgical technique, are essential for reducing the risk of postoperative infections.[2,5,6]
Implant failure remains a significant concern, albeit with a relatively lower incidence compared to infection. Factors contributing to implant failure include inadequate osseointegration, peri-implant bone loss, and biomechanical overload. Attention to patient selection, proper implant placement, and appropriate prosthetic design are essential for minimizing the risk of implant failure.[4,5,6]
Peri-implantitis emerged as another prevalent complication, highlighting the importance of long-term maintenance and monitoring of dental implants. Peri-implantitis, characterized by inflammation and bone loss around dental implants, presents a significant challenge in implant dentistry. It not only compromises the stability of the implant but also poses a risk to adjacent teeth and supporting structures. Prevention and early detection of peri-implantitis through regular monitoring and maintenance protocols are crucial for preserving peri-implant tissue health and implant longevity. Additionally, treatment modalities such as mechanical debridement, antimicrobial therapy, and surgical intervention may be necessary to manage established peri-implantitis cases effectively.[3,5,7]
Addressing the issue of infection is paramount given its relatively high prevalence in this research. Postoperative infections can not only compromise the success of the implant but also pose risks to systemic health. Therefore, strategies such as meticulous surgical technique, prophylactic antibiotics, and strict adherence to aseptic protocols are imperative in reducing the incidence of infections.[1,2,4]
Moreover, the occurrence of implant failure underscores the multifactorial nature of this complication. Factors such as inadequate bone quality and quantity, improper implant placement, occlusal overload, and systemic conditions like diabetes can contribute to implant failure. Understanding these risk factors and implementing appropriate treatment protocols tailored to individual patient needs are essential for minimizing the risk of implant failure and ensuring long-term implant success.[5,6,7,8]
Furthermore, the association between age and postoperative complications raises important considerations in treatment planning and risk assessment. Younger patients may have higher metabolic demands and lifestyle factors that could predispose them to a greater risk of complications. Conversely, older patients may present with systemic conditions and reduced bone density, which may affect implant success.[9,10] Tailoring treatment approaches and closely monitoring patients based on age-related factors can help mitigate risks and optimize treatment outcomes across different age groups.
CONCLUSION
Overall, this research underscores the importance of comprehensive risk assessment, meticulous surgical technique, and vigilant postoperative care in minimizing complications and maximizing the success of dental implant surgery. Continued research and clinical vigilance are essential for advancing our understanding of implant-related complications and enhancing patient care in implant dentistry.
