Is It Safe to Have Dental Implants After Orthognathic Surgery?
If you have already undergone jaw surgery — known clinically as orthognathic surgery — and are now considering dental implants to replace missing teeth or complete your smile restoration, you may be wondering whether the two treatments are compatible. It is entirely understandable to want clear information before exploring further options, and many patients across London ask exactly this question.
The relationship between dental implants after orthognathic surgery is a nuanced one. The answer depends on a range of individual clinical factors, including how long ago your jaw surgery took place, the extent of bone changes that occurred, your current oral health, and what your overall treatment goals are. While the combination of these two treatments is often possible and can yield excellent functional outcomes, it requires careful planning and assessment by a qualified dental professional.
This article aims to provide clear, balanced educational information to help you understand the considerations involved — so that you feel informed and prepared when discussing your options at a consultation.

Can you have dental implants after orthognathic surgery?
In many cases, dental implants after orthognathic surgery are considered safe and clinically appropriate, provided sufficient time has elapsed for jaw bone healing and stabilisation. Suitability depends on bone volume, soft tissue health, and surgical outcomes. A thorough clinical assessment is essential before any implant treatment is planned.
Understanding Orthognathic Surgery: What It Involves
Orthognathic surgery is a form of corrective jaw surgery carried out to address significant skeletal discrepancies — such as an underbite, overbite, crossbite, or asymmetry — that cannot be resolved with orthodontic treatment alone. The procedure involves repositioning the upper jaw (maxilla), the lower jaw (mandible), or both, to improve function, facial aesthetics, and in some cases, breathing and speech.
The surgery is typically performed under general anaesthesia by an oral and maxillofacial surgeon, often in combination with orthodontic treatment both before and after the procedure. Recovery can span several months, with full skeletal consolidation sometimes taking up to 12 to 18 months, depending on the nature and complexity of the surgery involved.
Because orthognathic surgery fundamentally alters jaw position and structure, it has a direct bearing on the bone environment into which dental implants would later be placed. This is why timing and post-surgical bone assessment are such important considerations when dental implants are being contemplated as part of a patient's longer-term restorative journey.
Understanding the extent and outcome of your jaw surgery is one of the first things a dental professional will want to establish before discussing implant suitability with you.
How Orthognathic Surgery Affects Jaw Bone Structure
One of the most important factors that determines whether dental implants are viable after orthognathic surgery is the condition of the jaw bone itself. Jaw surgery can alter bone dimensions, density, and vascularity — all of which are critical to successful implant integration.
During orthognathic surgery, sections of bone are cut and repositioned using plates and screws. Over time, these repositioned segments fuse and remodel. However, in some cases, the procedure can result in areas of reduced bone volume, altered blood supply, or slight changes to the bone's architecture. These changes may affect the quantity and quality of bone available for implant placement.
Bone grafting may sometimes be required prior to or at the time of implant surgery if bone volume is insufficient. This is a well-established clinical approach and is not uncommon in patients with a history of jaw surgery. A cone beam CT scan (CBCT) is typically used to evaluate bone dimensions and plan implant placement with precision.
The good news is that when orthognathic surgery has been performed successfully and healing is complete, the remodelled bone can often provide a sound foundation for dental implants — making careful assessment rather than automatic exclusion the appropriate approach.
The Importance of Timing: When Can Implants Be Considered?
Timing is perhaps the single most critical variable in determining when dental implants after orthognathic surgery can be safely considered. Attempting to place implants before the jaw has fully healed and stabilised could compromise both the implant outcome and the results of the original surgery.
As a general principle, most clinicians recommend waiting until the jaw bone has fully consolidated following orthognathic surgery before proceeding with implant placement. This typically means a minimum waiting period of 12 to 18 months post-surgery, though this will vary based on:
- The type and complexity of the jaw surgery performed
- Whether bone grafts were used as part of the orthognathic procedure
- The individual's rate of bone healing and overall health
- Whether orthodontic treatment following surgery has been completed
It is also worth noting that many patients undergo orthodontic treatment after jaw surgery to refine their bite, and this phase needs to be complete before implant positions are finalised — as tooth movement during orthodontics can affect the ideal implant site.
Your dental professional and, where relevant, your oral surgeon will work collaboratively to determine the most appropriate time to begin the implant planning process. You can learn more about the dental implant treatment process and what initial assessments involve.
Clinical Factors That Influence Implant Suitability
Beyond timing, a range of other clinical factors will be evaluated before dental implants can be recommended following orthognathic surgery. These include:
Bone volume and density: Sufficient bone height, width, and density are required to support implant fixtures securely. A CBCT scan provides detailed three-dimensional imaging to assess this.
Gum and soft tissue health: Healthy gum tissue is essential for implant success. Any signs of gum disease or soft tissue compromise will need to be addressed before implant treatment can proceed.
General medical health: Certain systemic conditions — such as uncontrolled diabetes or immune system disorders — and medications, including bisphosphonates, can influence healing and implant success rates. A thorough medical history review is always undertaken.
Smoking status: Smoking is a recognised risk factor for implant failure, as it impairs healing and increases infection risk.
Oral hygiene: Good home care habits are essential both before and after implant placement to protect against peri-implant complications.
Occlusion (bite): The relationship between the upper and lower teeth after jaw surgery must be assessed to ensure implants can be positioned and loaded correctly within the bite.
None of these factors are assessed in isolation — your clinician will consider your overall picture and discuss findings with you clearly and without pressure.
The Science Behind Osseointegration and Why It Matters Here
To understand why bone health is so central to implant success after orthognathic surgery, it helps to understand a process called osseointegration. This is the biological mechanism by which a dental implant — typically a small titanium fixture — becomes anchored within the jaw bone.
Titanium is a biocompatible material, meaning the body does not reject it. Over a period of weeks to months following implant placement, bone cells gradually grow onto and around the implant surface, creating a stable biological bond. This process is what gives dental implants their characteristic stability and longevity.
For osseointegration to succeed, several conditions must be met:
- There must be adequate bone volume surrounding the implant
- The bone must have a healthy blood supply to support cellular activity
- The site must remain free from infection during the healing period
- The implant must not be placed under excessive functional load too early
After orthognathic surgery, changes to the jaw's blood supply, bone density, or structure can potentially affect any of these conditions. This is why a thorough pre-implant assessment — including imaging and clinical evaluation — is so important in patients with a surgical jaw history. It ensures that osseointegration conditions are as favourable as possible before proceeding.
When a Professional Dental Assessment May Be Appropriate
If you have had orthognathic surgery and are considering dental implants, there are several situations in which seeking a professional dental evaluation sooner rather than later would be appropriate:
- You notice areas of missing teeth that are affecting your bite, chewing ability, or confidence
- You experience sensitivity, discomfort, or changes in the areas where implants are being considered
- You are uncertain whether enough time has passed since your jaw surgery for implant treatment to be appropriate
- Your orthodontic treatment following jaw surgery has recently been completed and you are ready to explore restorative options
- You have been told in the past that implants may not be suitable, but wish to receive an updated assessment
- You notice any swelling, pain, or changes in gum tissue around existing teeth or surgical sites
It is important to emphasise that experiencing any of the above does not necessarily indicate a problem — rather, these are simply circumstances where clinical input can provide clarity and guide next steps. A calm and thorough consultation with a qualified dental professional will always be the most reliable starting point.
If you have questions about implant assessment consultations, speaking directly with a clinician is a reliable way to receive guidance tailored to your specific circumstances.
Bone Grafting as a Supportive Option
In some patients who have had orthognathic surgery, the available bone at the intended implant site may be insufficient to support an implant fixture safely. This is not necessarily a barrier to implant treatment — rather, it is a clinical finding that can often be addressed through bone grafting.
Bone grafting is a well-established procedure in implant dentistry. It involves augmenting an area of deficient bone using grafting material — which may be sourced from the patient's own body (autograft), from a processed human donor source (allograft), from animal-derived materials (xenograft), or from synthetic options (alloplast). Over time, this material integrates with the existing bone and creates a more robust foundation for implant placement.
In patients with an orthognathic surgical history, the need for grafting is not uncommon, particularly where jaw repositioning has altered the dimensions of the alveolar bone — the ridge that supports teeth. The decision to graft and the choice of grafting material will depend on the degree of bone deficiency and other individual clinical factors.
Bone grafting adds a stage to the overall treatment timeline, but it significantly expands the number of patients who can ultimately benefit from dental implants as a long-term tooth replacement solution.
Maintaining Oral Health Before and After Implant Treatment
Whether or not you ultimately proceed with dental implants after orthognathic surgery, maintaining excellent oral health throughout is essential — both for protecting your existing teeth and for maximising the likelihood of a successful outcome if implant treatment does go ahead.
Practical oral health advice includes:
- Brushing twice daily with a fluoride toothpaste, using a technique recommended by your dental professional
- Interdental cleaning — using floss, interdental brushes, or a water flosser daily to remove plaque from between teeth
- Regular dental check-ups — attending routine appointments allows your dentist to monitor bone health, gum condition, and any changes around surgical sites
- Avoiding smoking — this is particularly important, as smoking significantly impairs healing and increases the risk of implant-related complications
- A balanced diet — limiting sugary foods and drinks reduces the risk of decay affecting teeth adjacent to planned implant sites
- Staying well hydrated — adequate hydration supports saliva production, which plays a key protective role in oral health
If you have had orthognathic surgery and wear retainers or other orthodontic appliances, maintaining these as instructed is also important for preserving the results of your jaw surgery — which in turn supports the bone environment for any future implant work.
Key Points to Remember
- Dental implants after orthognathic surgery are often clinically feasible but require careful individual assessment
- Timing is critical — most clinicians advise waiting at least 12 to 18 months after jaw surgery before implant placement is considered
- Bone volume, density, and soft tissue health are all evaluated before any implant treatment is planned
- Bone grafting may be recommended if available bone is insufficient — this is a common and well-established adjunct to implant treatment
- Smoking, systemic health conditions, and poor oral hygiene are factors that can affect implant success and will be discussed at consultation
- A thorough clinical assessment, including 3D imaging, is the essential first step in determining suitability
- Treatment planning in this context is often a collaborative effort involving dental implant clinicians and, in some cases, oral surgeons
Frequently Asked Questions
How long after jaw surgery do I need to wait before getting dental implants?
Most dental professionals recommend waiting a minimum of 12 to 18 months after orthognathic surgery before proceeding with dental implants. This allows time for the jaw bone to fully heal, remodel, and stabilise following the repositioning that occurred during surgery. In some cases, if orthodontic treatment is continuing post-surgically, implant placement would typically not be planned until that phase is complete. Your clinician will assess your individual healing progress and advise you on the most appropriate timing for your situation.
Will I definitely need a bone graft before implants after jaw surgery?
Not necessarily. Many patients who have had orthognathic surgery retain adequate bone volume for implant placement without any additional grafting. However, in cases where jaw repositioning has reduced available bone, or where bone density is lower than required, grafting may be recommended as a preparatory step. A detailed three-dimensional scan of your jaw will allow your dental team to assess bone dimensions accurately and advise you clearly on whether grafting is likely to be needed before any treatment begins.
Can orthognathic surgery affect the success of dental implants?
Orthognathic surgery can influence the bone environment in which implants are placed, which is why thorough pre-treatment assessment is so important. Changes to bone dimensions, vascularisation, or density following jaw surgery may present considerations — but in many cases, once healing is complete and the bone has stabilised, successful implant outcomes are achievable. Factors such as overall health, smoking status, and oral hygiene also play a significant role in implant success alongside surgical history.
What imaging is used to plan dental implants after jaw surgery?
A cone beam computed tomography scan (CBCT) is commonly used to plan dental implants, particularly in patients with a history of jaw surgery. This specialist form of 3D dental imaging provides detailed information about bone height, width, and density, as well as the proximity of anatomical structures such as nerves and the sinus cavities. This level of detail allows for precise, safe implant planning and helps identify whether bone grafting may be required before treatment proceeds.
Is it safe to have dental implants if I still have plates and screws from my jaw surgery?
In most cases, the titanium plates and screws used to stabilise bone during orthognathic surgery are either removed before implant placement or are positioned in areas that do not interfere with planned implant sites. Your dental and surgical team will review your surgical records and current imaging to assess whether any hardware is present that requires removal or might influence implant placement decisions. This is an important part of the pre-treatment planning process and will be discussed with you during your consultation.
Do dental implants after orthognathic surgery look and feel natural?
When dental implants are appropriately planned, placed, and restored, they aim to closely replicate the appearance and function of natural teeth, though individual outcomes will vary based on clinical circumstances. The crown or prosthesis placed on the implant is customised in shape, size, and shade to complement your existing teeth and the bite alignment achieved through your jaw surgery. Your dental professional will discuss realistic expectations with you during the planning process — helping you understand what can be achieved in your specific case.
Conclusion
The question of whether dental implants are safe after orthognathic surgery is one that deserves a considered, individual answer — and the reassuring reality is that for many patients, the combination of these two treatments can form part of a successful, comprehensive dental restoration journey.
Dental implants after orthognathic surgery are often clinically appropriate, but the path to treatment requires patience, thorough planning, and collaboration between dental professionals with relevant expertise. The key considerations — timing, bone quality, soft tissue health, and overall wellbeing — are all factors that a qualified clinician will explore with you in detail before any treatment is recommended.
If you have had jaw surgery and are wondering whether implants might be right for you, the most important step is to arrange a professional consultation so that your individual circumstances can be properly assessed. There is no one-size-fits-all answer, but with the right clinical evaluation, a clear and personalised treatment pathway can be established.
