Orthodontic retention remains a critical component in maintaining the outcomes of orthodontic treatment, particularly in adult populations where relapse is common. Traditionally, fixed and removable retainers have been the standard of care for post-treatment stabilization. However, recent evidence supports the use of dental implants as an adjunctive or alternative method for long-term orthodontic retention.
From increased biomechanical reliability to reduced patient compliance concerns, implants are redefining retention strategies in adult orthodontics.

This review explores current literature that evaluates the use of dental implants for maintaining post-orthodontic alignment and occlusion.
Understanding Orthodontic Retention: Clinical Importance and Challenges
Orthodontic retention refers to the phase following active orthodontic treatment, during which the results are stabilized and maintained. Without adequate retention, the teeth often revert to their original positions due to periodontal ligament memory, continued growth, or neuromuscular influences. The orthodontic retention phase is, therefore, crucial in securing treatment outcomes, especially in adults and cases involving complex malocclusions.
The most common retention strategies involve the use of fixed bonded wires or removable acrylic plates. These devices, however, are subject to wear, patient non-compliance, and failure over time.
Additionally, challenges such as gingival inflammation and plaque accumulation around fixed retainers have raised questions about the long-term viability of traditional retention methods. As a result, alternative strategies – including the use of osseointegrated implants – are being explored to address these limitations.
Dental Implants as Anchorage Devices in Orthodontics
Dental implants have been employed as stationary anchorage units during orthodontic treatment for over two decades. Their non-movable nature and excellent biomechanical stability offer clinicians a highly effective anchorage system, especially in adults.
Implants can withstand the multidirectional forces applied during orthodontic mechanics without displacement, making them a reliable tool in difficult tooth movements.
More recently, studies have assessed their utility beyond active orthodontic therapy, specifically in the retention phase. Implants, once integrated, become a permanent fixture within the alveolar bone. This permanence offers a unique opportunity to utilize implants as abutments for retainers or prostheses that contribute to long-term stabilization of occlusion and alignment.
Review of Clinical Evidence Supporting Implant-Assisted Retention
Several peer-reviewed studies have evaluated the effectiveness of implants in both orthodontic anchorage and long-term retention. A 2016 study evaluated osseointegrated implants subjected to orthodontic forces over three years. The researchers concluded that the implants remained stable and effective as abutments for permanent prostheses following treatment, indicating their viability for orthodontic retention.
Further studies assessed single implants loaded immediately after placement and utilized for orthodontic anchorage. The long-term follow-up confirmed implant survival and stability, suggesting that early loading under orthodontic force does not impair osseointegration or longevity. These findings support the hypothesis that implants can successfully transition from active orthodontic devices to long-term retention units.
Case Reports and Longitudinal Studies
Beyond randomized trials, case studies provide insight into real-world applications. One such report discussed the management of a 23-year-old female with a Class II Division 2 malocclusion and a unilateral scissors-bite. Mini-implants were used to assist in complex tooth movements. The treatment results, including facial profile and dental alignment, were maintained for several years, demonstrating the durability of implant-assisted retention strategies in managing complex orthodontic cases.
Moreover, research on retrieved mini-implants has shown that surface deterioration and chemical composition changes occur with prolonged use, specifically beyond six months. While this indicates limitations for temporary mini-implants, it also underscores the stability of fully osseointegrated implants used as permanent retainers. Clinicians must thus carefully differentiate between temporary anchorage devices (TADs) and conventional implants when considering their long-term application in orthodontic retention.
Implant Placement Considerations for Retentive Purposes
Using implants for orthodontic retention necessitates meticulous treatment planning. Factors such as implant positioning, timing of placement, and biomechanical loading must be tailored to each patient’s needs. Anterior mandibular implants may be indicated in cases of severe crowding relapse, while posterior implants can help maintain vertical control in deep bite correction.
Furthermore, implant-retained prostheses or bar systems can be custom-fabricated to serve as permanent retainers. These solutions offer improved aesthetics, reduced risk of compliance-related failure, and the potential to simultaneously address edentulous spaces, providing dual functionality.
However, careful patient selection is paramount. Ideal candidates are typically adults with fully matured skeletal growth and stable periodontal health. Radiographic analysis and 3D imaging aid in precise planning, ensuring that implant placement supports both functional and esthetic objectives of retention.
Comparing Implant Retention to Conventional Methods
When comparing dental implants to traditional retention methods, both advantages and limitations emerge. Conventional fixed retainers are simple, cost-effective, and minimally invasive, but they are prone to breakage and plaque accumulation. Removable appliances, while hygienic, suffer from poor compliance.
In contrast, implants eliminate compliance issues and offer superior mechanical stability. They can serve as fixed abutments for customized splints or bridges that inherently preserve tooth position. Yet, implant procedures are invasive and more costly, and improper placement may lead to unfavorable esthetic or periodontal outcomes.
A recent study evaluated the long-term success of different fixed retainers over a 10- to 15-year period. Although favorable outcomes were observed, retention effectiveness varied significantly depending on wire design and bonding technique. This variability underscores the need for alternative strategies such as implants, especially in high-risk cases or when retention failure has previously occurred.
Long-Term Prognosis and Maintenance
The long-term prognosis of implant-assisted orthodontic retention appears promising when strict clinical protocols are followed. Osseointegration must be achieved prior to functional loading, and patients should be monitored routinely to detect any peri-implant pathology. Oral hygiene instruction, professional maintenance, and radiographic assessments are critical in preserving implant health.
Emerging technologies, including digital workflows and guided implant surgery, have further enhanced the precision of implant placement for orthodontic retention purposes. These innovations allow for optimized positioning that ensures biomechanical efficiency and aesthetic harmony, contributing to long-term treatment stability.
