Interview: "Dynamic navigation links digital treatment planning to real-time surgical execution"— Dr Sanjay Jain

Dynamic navigation is reshaping implant dentistry by bringing real-time surgical guidance into the operating field. By integrating three-dimensional imaging, digital treatment planning, and optical tracking, the technology lets clinicians monitor implant drill position, angulation, and depth throughout surgery, helping translate a virtual plan into a more predictable clinical outcome.

Dr Sanjay Jain defended his thesis, “Safe and Accurate Immediate Implant Placement in the Posterior Maxilla: The Role of Dynamic Navigation in Transcrestal Sinus Augmentation”, on 12 May 2026, and he was awarded his PhD on 26 June 2026. His research addresses an important clinical question: how can real-time navigation improve precision and predictability when implant placement is complicated by anatomical constraints in the posterior maxilla?

In this interview on real-time surgical guidance, clinical accuracy and the evolving role of digital technologies in implant dentistry, Dr Jain discusses the clinical significance of dynamic navigation, its advantages and limitations, its role in education, and the possibilities emerging from integrating artificial intelligence, augmented reality, and robotic-assisted surgery.

The fundamental objective of implant dentistry has always been to place implants precisely while preserving anatomical structures and ensuring long-term biological and prosthetic success.

Traditionally, clinicians have relied on their anatomical knowledge, clinical experience and tactile perception to position implants. Static computer-guided surgery introduced greater predictability by transferring a virtual plan to the surgical field through a prefabricated guide. Dynamic navigation takes this process further by providing continuous visual feedback during surgery, supporting accuracy and helping clinicians maintain control of the planned trajectory.

Dynamic navigation is a significant advancement because it links digital treatment planning to real-time surgical execution.

The clinician can monitor the drill’s position, angulation, and depth in relation to the planned implant trajectory. If the drill deviates from the intended path, the system helps the operator identify and correct that deviation during the procedure.

The important distinction is that dynamic navigation does not simply tell us where an implant should be placed; it helps us execute the plan while retaining the flexibility to respond to clinical conditions. This combination of precision, visualisation, and adaptability makes the technology particularly valuable.

The posterior maxilla presents distinct anatomical and surgical challenges. Bone availability may be limited by the position of the maxillary sinus, and the quality and quantity of the residual alveolar bone can vary considerably between patients. When considering immediate implant placement and sinus augmentation, carefully assess available bone, sinus anatomy, and the proposed implant position.

Transcrestal sinus augmentation requires controlled manipulation of the sinus floor while minimising the risk of complications, particularly injury to the Schneiderian membrane. At the same time, the clinician must maintain an appropriate implant trajectory and achieve the primary stability necessary for the intended treatment protocol.

These procedures leave little room for imprecise execution.

Dynamic navigation monitors the instrument’s position and trajectory in real time, helping the clinician stay oriented to the preoperative plan.

However, navigation should be considered one component of a comprehensive treatment strategy. Appropriate case selection, detailed radiographic assessment, sound surgical technique and an understanding of sinus anatomy remain indispensable. The technology can support precision, but it cannot eliminate biological variability or surgical risk.

Each approach has its place in clinical practice, and the choice should be guided by the clinical situation, the clinician’s expertise and the available resources.

Freehand implant placement offers considerable flexibility and does not require a navigation system or a prefabricated guide. However, its accuracy depends heavily on the clinician’s experience, spatial judgement and ability to translate the treatment plan into the surgical field.

Static guided surgery provides a predetermined pathway through a surgical guide fabricated from digital planning data. It can offer high accuracy, but the guide may constrain intra-operative adjustments. If clinical circumstances differ from those anticipated during planning, modifying the trajectory can be difficult.

Dynamic navigation combines the benefits of digital planning with intra-operative flexibility. It continuously tracks the surgical instrument and displays its position relative to the planned trajectory, allowing the clinician to adjust as needed.

That said, dynamic navigation is not inherently superior in every clinical situation. Accuracy depends on several factors, including system calibration, patient registration, operator experience and the specific surgical protocol. Both static and dynamic guidance can support accurate implant placement when used appropriately. Select the method that best meets each case's clinical requirements.

The principal benefit is the potential to improve control over implant positioning. This is particularly relevant when working near critical anatomical structures, such as the inferior alveolar nerve, mental foramen, maxillary sinus or adjacent tooth roots.

Accurate implant placement also has implications beyond surgery. It influences the restorative emergence profile, prosthetic design, occlusal relationships and accessibility for oral hygiene. When implants are placed according to a well-designed prosthetic plan, the restorative phase becomes more straightforward and predictable.

Dynamic navigation may also support minimally invasive approaches, including flapless surgery, when the anatomy and clinical circumstances permit. Reduced surgical access can help minimise tissue trauma and post-operative morbidity in appropriately selected cases.

However, it is important to distinguish between the benefits of accurate navigation and the outcomes of the entire treatment protocol. Reduced discomfort, faster recovery and successful immediate placement or loading depend on multiple factors, including the patient’s condition, surgical complexity, primary stability and restorative planning. Navigation can contribute to these objectives, but it does not guarantee them.

Beyond implantology, dynamic navigation also has applications in endodontics and selected oral and maxillo-facial surgical procedures, including procedures involving orthognathic surgery. These applications further demonstrate the potential of real-time navigation across different areas of dentistry and surgery.

Implant positioning should start with the intended restoration rather than just the available bone. The implant must be placed to support appropriate emergence, function, cleansability, and long-term maintenance while respecting the surrounding anatomy.

Digital planning lets the clinician evaluate the proposed implant position relative to the final prosthesis and available bone. Dynamic navigation then helps transfer that plan to the surgical field.

This integration can be especially useful when small deviations in implant angulation or depth may complicate restorative treatment. Appropriate positioning may facilitate the use of suitable abutments, improve access for oral hygiene and support favourable biomechanical conditions.

Nevertheless, restorative success also depends on implant design, bone quality, soft-tissue management, occlusal planning and maintenance. Navigation improves the clinician’s ability to execute a plan; the plan's quality remains equally important.

Digital dentistry's strength lies in integrating different technologies rather than using individual devices in isolation.

A comprehensive workflow may begin with CBCT imaging to assess the anatomy and available bone. Intraoral scanning provides information about the dentition and soft-tissue surfaces, while digital planning software lets the clinician evaluate the proposed implant position relative to the restorative objective.

The resulting plan can then be transferred to the surgical environment through static guidance or dynamic navigation. Digital impressions, CAD/CAM workflows and prosthetic design can subsequently support the restorative phase.

When these components are properly integrated, communication among the implant surgeon, restorative dentist and dental technician becomes more efficient. Digital visualisation also helps the patient better understand the proposed treatment.

The challenge is ensuring that each stage is accurate and that the data are correctly aligned. Digital workflows are only as reliable as their underlying imaging, registration, planning and execution.

Doctoral research offers an opportunity to examine a clinical problem systematically, critically evaluate available evidence, and investigate how emerging technologies may improve treatment protocols.

My thesis, “Safe and Accurate Immediate Implant Placement in the Posterior Maxilla: The Role of Dynamic Navigation in Transcrestal Sinus Augmentation”, brings together two important areas of contemporary implantology: immediate implant placement and the use of real-time navigation in anatomically demanding situations.

The University of Szeged’s Albert Szent-Györgyi Medical School provided the academic setting for this research and its formal doctoral evaluation. The open defence was an important opportunity to present the work, discuss its scientific and clinical relevance, and engage with experts in the field.

My mentor, Dr Katalin Nagy, has led digital dentistry for several decades. Her academic guidance was invaluable in conducting this study. We combined rigorous academic input with documented clinical cases, following the University’s prescribed research protocols. This approach helped us examine the clinical application of dynamic navigation within a structured academic framework.

For me, research in this area ultimately connects technological innovation with clinically meaningful questions. The objective is not to adopt technology simply because it is new, but to understand where it offers measurable value, what its limitations are, and how to incorporate it responsibly into patient care.

One of dynamic navigation's most valuable aspects is the immediate visual feedback it provides. Implant surgery requires the clinician to interpret three-dimensional anatomy and translate that understanding into controlled hand movements. This can be difficult for trainees who are still developing spatial awareness and surgical confidence.

Navigation lets students see how the planned trajectory relates to the instrument's actual position. They can identify deviations, understand how changes in angulation and depth affect the instrument, and review their performance.

This creates opportunities for structured training, objective assessment and reflection. Experienced clinicians can also use the technology to refine their technique and evaluate surgical performance.

However, training should not become dependent on the display alone. Students must continue to develop anatomical knowledge, tactile awareness, surgical judgement and the ability to manage unexpected situations. Navigation should complement these fundamental skills, not replace them.

Cost is an important consideration. Dynamic navigation requires investment in the navigation platform, compatible instruments, software and maintenance. Clinics must also account for training, workflow integration and the time required to establish reliable protocols.

Beyond financial considerations, the technology demands careful calibration and accurate patient registration. Optical tracking must remain reliable throughout the procedure, and the clinical team must understand how to identify and address technical interruptions.

Another significant challenge is the learning curve. Dental education has traditionally emphasised visualising the operative area through direct or indirect vision. Dynamic navigation adds a new demand: clinicians must coordinate hand movements with information displayed on a monitor. Synchronising eye–mind–hand co-ordination can be challenging at first, particularly for operators accustomed to conventional visual guidance. Structured training and repeated practice are therefore essential for developing confidence and proficiency.

To broaden adoption, manufacturers and training institutions need to make the technology more accessible through appropriate educational programmes, reliable technical support, and efficient clinical workflows.

In markets such as India, adoption will also depend on whether the technology offers meaningful value for the patient population and the clinical setting. The decision to invest should be based on the practice’s case mix, treatment objectives and capacity to use the system effectively.

Ultimately, technology adoption should be driven by clinical need and demonstrable benefit rather than novelty alone.

These technologies can complement one another and further advance precision dentistry.

Artificial intelligence may assist with image analysis, anatomical segmentation, risk assessment, and treatment planning. These applications could help clinicians evaluate complex cases more efficiently, but their recommendations will need clinical validation and professional oversight.

Augmented reality could present navigation information more directly in the clinician’s field of view. This may reduce the need to alternate attention between the patient and a separate monitor, provided the technology can deliver reliable visualisation without compromising the operator’s view.

Robotic-assisted surgery may offer another layer of control and reproducibility. In combination with navigation, robotic systems could help clinicians maintain a planned trajectory while retaining appropriate clinical supervision.

The most promising future likely involves the coordinated use of these technologies within a validated digital workflow. Their success will depend not only on technical sophistication but also on safety, evidence, usability and integration into everyday clinical practice.

I would encourage clinicians to begin with a clear understanding of the clinical problems they want the technology to address.

A sound foundation in implant anatomy, treatment planning, surgical principles and restorative requirements is essential. Clinicians should then undertake structured training on the chosen navigation platform, understand its calibration and registration protocols, and practise in controlled settings before using it in increasingly complex clinical situations.

Clinicians should also establish a consistent digital workflow and develop contingency plans for technical interruptions. Clinicians should use navigation only within their competence and with appropriate patient selection.

Most importantly, clinicians should critically evaluate outcomes. Technology should improve decision-making and surgical execution in ways that matter to patients. It should not create a false sense of security or encourage operators to undertake cases beyond their capabilities.

Implant dentistry is moving towards increasingly integrated, data-driven and patient-specific treatment. Digital imaging and planning have already changed how we diagnose and prepare for implant procedures. Dynamic navigation extends those capabilities into the surgical phase by connecting the virtual plan with real-time clinical execution.

As navigation systems evolve and become more accessible, they may play an increasingly important role in complex implant procedures, education and quality assurance. Integrating artificial intelligence, augmented reality, and robotic assistance could further improve the consistency of digital workflows.

At the same time, the fundamental principles of implant dentistry will remain unchanged. Successful treatment requires accurate diagnosis, appropriate case selection, respect for biological limitations, sound surgical technique and a restoration designed around the patient’s needs.

The future is not about replacing the clinician with technology. It is about equipping clinicians with better information, improved visualisation and greater control so that they can make better-informed decisions.

Dynamic navigation is an important step in that direction. Its real value will ultimately be measured not by the sophistication of the technology, but by its contribution to safe, predictable and sustainable patient care.
