An implant post in the bone is only the beginning. What matters just as much — and is often less visible to patients — is where that post goes: the angle, the depth, and the precise three-dimensional position relative to the surrounding teeth, the nerve, and the final crown that will sit on top.
Get the position right, and the implant functions naturally, cleans easily, and looks like it belongs. Get it wrong, and even a perfectly integrated implant can produce a crown that is hard to clean, sits awkwardly in the bite, or causes problems years down the track.
This is why the planning that happens before surgery matters as much as the surgery itself. And it is why, for many cases, we now use a digital planning workflow and a surgical guide — a custom 3D-printed device that puts the plan into physical form on the day.
Freehand vs Guided Placement: What the Difference Actually Means
Dental implants have been placed freehand — based on X-rays, clinical experience, and careful judgement in the moment — for decades. For many straightforward single-tooth cases in experienced hands, freehand placement remains a reasonable approach. It is worth being honest about that rather than suggesting that anything less than full digital planning is inadequate.
The difference with guided placement is this: the implant position is decided on a computer, in three dimensions, before surgery begins. A custom surgical guide — fabricated specifically for your anatomy — is then fitted over your teeth or gums on surgery day. The guide contains a precisely positioned sleeve that physically directs the drill to the planned angle and depth.
This means the plan made on the computer translates directly into where the drill goes. The surgeon is not interpreting a 2D X-ray or estimating angles in the moment — the geometry is built into the guide itself.
What guided surgery improves is planning precision and predictability. It allows the position to be driven by the final restoration (the crown) rather than by what feels right during surgery. This is called restoratively-driven implant placement, and it tends to produce better aesthetic and functional outcomes, particularly for front teeth and complex cases.
What it does not do is eliminate surgical risk, guarantee a particular outcome, or remove the need for clinical skill. The guide directs placement — but healing, bone quality, aftercare, and the dentist’s judgement all still shape the result.
The Digital Workflow at Sunny Dental Buderim: Step by Step
Here is how the process works in practice.
Step 1: Intraoral Scan (In-House)
The starting point is a precise digital map of your teeth and gums. We take this in-house using an intraoral scanner — a wand that scans your mouth and builds a 3D model in seconds.
No trays, no impression material, no gag reflex from a tray full of putty. The digital scan is more comfortable than traditional impressions, and the resulting model is immediately available for planning.
Step 2: CBCT 3D Scan (Referred Out)
A standard dental X-ray is two-dimensional. It gives useful information, but it cannot show depth — how much bone exists in three dimensions, exactly where a nerve runs, or the precise contour of the sinus.
For implant planning, we use a Cone Beam CT (CBCT) scan, which produces a full 3D image of the jaw. This is where we refer you to a local medical imaging provider — typically within the Sunshine Coast area.
We refer this out for a straightforward reason: dedicated imaging equipment, operated by imaging specialists, produces better quality scans than an in-house unit we might use occasionally. The CBCT scanner at a radiology centre is their primary tool. It is calibrated, maintained, and operated by people who do this all day. For a procedure where the 3D anatomy matters as much as it does in implant surgery, this is the right call.
The cost of a CBCT scan is typically in the range of $250 to $600, depending on the provider and the scope of imaging needed. We will tell you what to expect before we refer you, and this cost is disclosed in your written treatment plan before any decisions are made.
Step 3: Planning Software Merges Both Scans
Once we have your intraoral scan and your CBCT, the two datasets are merged in planning software. This gives us a complete picture: the shape of your teeth and gums overlaid on the 3D bone anatomy underneath.
In this environment, we can position the implant virtually — seeing exactly where it sits in relation to your bone, your nerve, your sinus, and the final crown. The crown position is planned first, and the implant position is worked backwards from there. This is what “restoratively-driven” means.
We can visualise clearances, check angulations, and test different positions before committing to anything.
Step 4: Surgical Guide Fabricated
Once the position is confirmed, the surgical guide is fabricated — typically by a dental laboratory using 3D printing. It is a custom-fit device, made specifically for your anatomy, that fits precisely over your teeth or gum tissue.
The guide contains a metal sleeve positioned at the planned angle. On surgery day, the drill passes through this sleeve. The geometry of the guide does the work of translating the digital plan into physical reality.
Step 5: Surgery Day with the Guide
The guide fits into place at the start of the procedure. Surgery then proceeds as described in our full guide to what to expect on implant surgery day — local anaesthetic, preparation of the site, placement of the implant post.
The difference from freehand placement is that the drill pathway is directed by the guide rather than by judgement alone. In many guided cases, the incision can be smaller — because the position is already confirmed, extensive access to verify landmarks is less necessary. Surgical time is often shorter for the same reason.
What a Surgical Guide Adds to Cost and Why It May Be Worth It
A surgical guide is an additional item in your treatment. The guide itself is fabricated by a laboratory, and that cost is passed on. The imaging referral (CBCT) is also a cost that does not exist in a freehand approach.
We do not give a blanket price for the guide here, because it varies depending on the laboratory used, the complexity of the case, and what your health fund covers. The guide will be itemised in your written treatment plan, along with everything else, before you commit to treatment.
What the additional cost tends to buy you:
- Restoratively-driven positioning — the crown drives the plan, not the other way around
- Smaller incisions in many cases — less disruption to surrounding tissue
- Shorter surgical time in many cases — because the plan is already locked in
- More predictable outcomes for complex anatomy — particularly near nerves, sinuses, or where bone volume is limited
Whether the guide is worth the additional investment is a conversation we have with each patient based on their specific case. For some straightforward single-tooth restorations in ideal positions, freehand placement by an experienced clinician is appropriate. For others, the guide is the right tool.
When Surgical Guides Matter Most
Guided surgery tends to add the most value in cases where the margin for error is smallest.
Multiple implants in the same arch. When several implants need to work together to support a bridge or full-arch restoration, the relative angulations matter. A guide ensures they are planned and placed as a system.
Full-arch rehabilitation. Cases involving All-on-4 or similar full-arch approaches rely on the implants being positioned to carry the entire load of a full-arch restoration. Digital planning and guides are standard for these cases.
Proximity to important anatomy. When the planned position is near the inferior alveolar nerve (which runs through the lower jaw) or the maxillary sinus (above the upper back teeth), a guide reduces the likelihood of encroaching on these structures.
Front teeth. The aesthetic demands of front tooth implants are significant. A millimetre of difference in position can affect how the crown emerges from the gum and how symmetrical it looks relative to adjacent teeth. Restoratively-driven planning is particularly valuable here.
Limited bone volume. When bone is narrow or reduced in height, the implant position may need to thread a precise path. A guide helps achieve this.
Honest Limits: What Guided Surgery Cannot Guarantee
Guided surgery improves planning. It does not change the biology.
An implant still needs bone to integrate with. It still depends on your healing capacity, your general health, and how well you follow aftercare instructions. Smoking still significantly increases the risk of failure. Poor oral hygiene after placement can still lead to peri-implantitis, regardless of how precisely the implant was positioned.
Some cases are also beyond what we handle at Sunny Dental, and we say so. Dr Louis George and Dr Jeremy Collins are general dentists with training and experience in implant surgery — they are not specialists in oral surgery, periodontics, or prosthodontics. Cases that require specialist input — significant bone grafting, complex sinus lifts, certain systemic health factors — will be referred appropriately. We would rather refer early than push through a case that carries more risk than we can comfortably manage.

Frequently Asked Questions
Does guided surgery cost more than freehand placement?
Yes, in most cases. The CBCT scan (referred out, typically $250–$600) and the fabricated surgical guide are both additional items. These costs are itemised in your written treatment plan before you agree to anything. Whether the additional investment is appropriate for your case is something we discuss at consultation.
Do I really need a CBCT scan?
For cases where we are using a surgical guide: yes. The guide is fabricated from the merged CBCT and intraoral scan data — without the CBCT, there is no meaningful 3D anatomy to plan from. Planning an implant position from a 2D X-ray alone and then fabricating a guide from that would not give you the benefit the guide is supposed to provide.
For simpler cases where guided surgery is not indicated, a CBCT may still be recommended to assess bone volume and identify important anatomy — but the decision is made case by case.
How long does the planning process take before surgery?
After your consultation, you will be referred for a CBCT scan. Once we receive the scan data, planning and guide fabrication typically take a few weeks. We will give you a realistic timeline at your consultation. We do not rush this step — good dentistry takes time, and the planning stage is where much of the work happens.
Is the surgical guide uncomfortable to wear during surgery?
The guide sits over your teeth or gums. You will not feel it in the same way you feel the procedure itself — the area is anaesthetised. Some patients notice the presence of the guide; most find it unremarkable. If you have concerns about comfort, raise them at your consultation.
What happens to the guide after surgery?
It is a single-use device for your specific procedure. It is not reused for future appointments.
Can guided surgery be done with sedation?
Yes. The presence of a surgical guide does not change what sedation options are available to you. If anxiety is a factor for you, discuss sedation with us at your consultation. Our Practice Manager Dwi George is a Registered Nurse and manages sedation in-house — this is covered in detail on our dental implants page.
Putting It Together
Digital implant planning and surgical guides are not about making a simple procedure unnecessarily complex. They are about making a precise procedure more predictable — planning in three dimensions, on a computer, before surgery begins, and carrying that plan through to execution with a custom-fit guide.
For the right case, this approach means the final crown sits where it was planned to sit, the position works with the bite, and the geometry makes cleaning straightforward for decades. That is the point of doing it.
