Digital Smile Design, SmileCloud, and Partial Extraction Therapy with Dr. David Attia
How digital treatment planning, CBCT segmentation, facial scanning, and biologically driven implant concepts are changing anterior esthetic dentistry.
The Future of Implant Dentistry Is Not Just Digital. It Is Biologically Driven.
In anterior implant dentistry, successful treatment planning is no longer limited to placing an implant where bone happens to exist. The restorative plan, smile design, facial architecture, soft tissue contours, occlusion, and biologic preservation strategy all need to be integrated before treatment begins.
In this episode of the Dental Digest Podcast, Dr. Melissa Seibert speaks with Dr. David Attia about the evolution of digital implant planning and the clinical importance of creating a true virtual patient. Rather than viewing a CBCT, intraoral scan, facial photo, and wax-up as disconnected records, Dr. Attia describes a workflow where these data sets are stacked into one interdisciplinary planning environment.
The conversation then moves into one of the most important biologic questions in esthetic implant dentistry: how do we preserve the hard and soft tissue architecture that makes an anterior implant look natural? Dr. Attia explains partial extraction therapy, socket shield therapy, pontic shield therapy, and root submergence as tools for preserving the patient’s existing periodontal tissues instead of trying to rebuild them after collapse.
Why the Virtual Patient Changes Multidisciplinary Dentistry
Anterior implant dentistry is not a single-procedure discipline. It requires restorative thinking, surgical precision, esthetic diagnosis, orthodontic awareness, periodontal respect, and a clear understanding of the patient’s facial envelope. Dr. Attia’s central premise is that digital dentistry becomes most powerful when it helps the entire team plan from the same clinical reality.
SmileCloud, CBCT Segmentation, and Data Stacking
Dr. Attia describes using platforms like SmileCloud alongside CBCT segmentation, intraoral scans, standardized photography, and facial scanning to create a more complete digital patient. The value is not simply that the software is impressive. The value is that it allows the restorative dentist, surgeon, orthodontist, and technician to visualize the same treatment plan before the patient is in the chair.
By aligning an STL scan with facial photographs, facial scans, and CBCT data, the team can better evaluate tooth position, restorative contours, proposed provisionals, surgical guides, crown lengthening guides, and esthetic limitations. In more complex rehabilitations, this workflow becomes less of a luxury and more of a clinical communication system.
The Double-Edged Sword of AI Smile Simulation
One of the more nuanced moments in this episode is Dr. Attia’s discussion of AI-driven smile simulation. These tools can help patients visualize a proposed outcome, but they also create ethical risk if the simulated result ignores biologic limitations. A beautiful digital preview can become misleading if bone, soft tissue, occlusion, restorative space, or surgical feasibility have not been properly considered.
This is one of the most clinically important distinctions in the episode: digital dentistry should not be used merely to sell dentistry. It should be used to diagnose more completely, treatment plan more responsibly, and communicate limitations more clearly.
Partial Extraction Therapy as Biologic Preservation
The second major theme is partial extraction therapy. Dr. Attia emphasizes that partial extraction therapy is not synonymous with socket shield alone. It is an umbrella category that includes socket shield therapy, proximal shields, pontic shields, and root submergence. Each technique uses retained root structure, in whole or in part, to preserve the periodontal tissues associated with that root.
Instead of extracting a tooth and then attempting to regenerate the collapsed ridge, partial extraction therapy asks whether the clinician can preserve the existing facial and interproximal architecture. In the anterior esthetic zone, where papillae and facial contours are difficult to recreate, this preservation-first philosophy can be transformative.
Why Prosthetics Can Ruin Good Surgery
Dr. Attia repeatedly returns to the relationship between surgery and prosthetics. In his view, surgical success in the anterior zone is inseparable from provisionalization and the final restorative outcome. A well-executed partial extraction therapy case can still fail esthetically if the provisional or final prosthesis violates the soft tissue contours, overloads the site, or fails to respect the biologic space created during surgery.
For clinicians, the practical message is clear: anterior implant treatment planning cannot be reduced to implant position alone. The emergence profile, provisional design, tissue support, restorative contours, and occlusal environment need to be planned as part of one system.
Clinical Takeaways
- Create the virtual patient: Combine CBCT data, intraoral scans, facial scans, photographs, and digital wax-ups to create a more complete interdisciplinary treatment plan.
- Use digital tools ethically: AI smile simulations can be powerful, but they must be constrained by biologic reality, restorative feasibility, and patient-specific limitations.
- Stack data for better communication: SmileCloud-style workflows allow surgeons, restorative dentists, orthodontists, and technicians to evaluate the same plan in a shared digital environment.
- Think beyond socket shield: Partial extraction therapy includes socket shields, proximal shields, pontic shields, and root submergence, each with distinct clinical indications.
- Preserve before rebuilding: In the anterior esthetic zone, retaining healthy root structure can preserve facial and interproximal tissue architecture that is difficult to regenerate later.
- Respect the prosthetic phase: Provisionalization and final restorative design can protect or destroy the biologic gains created during surgery.
Key Questions This Episode Helps Answer
- How does SmileCloud help with implant treatment planning? It allows clinicians to stack photographs, intraoral scans, CBCT data, facial scans, wax-ups, and proposed restorations into a shared digital planning environment.
- When is digital smile design most valuable? It is especially valuable in esthetic cases, rehabilitations, multidisciplinary treatment plans, and anterior implant cases where tooth position, tissue architecture, and facial esthetics must be coordinated.
- What is partial extraction therapy? Partial extraction therapy is a group of techniques that preserve all or part of a non-restorable tooth root to maintain the periodontal tissues associated with that root.
- What is the socket shield technique? Socket shield therapy retains a prepared buccal root fragment to help preserve facial bone and soft tissue contours during implant therapy.
- Why does provisionalization matter in anterior implant dentistry? The provisional restoration or custom healing abutment helps preserve the emergence profile, soft tissue support, and esthetic architecture during healing.

Dr. Melissa Seibert: Hey, I want to tell you about something I put together for you. I created a free PDF guide that walks you step-by-step through the injection molding technique. I love this technique because it is one of the best ways to get predictable, beautiful, and highly aesthetic anterior composites. You're actually injecting the composite directly into the tooth using a clear template which makes it far more consistent and efficient. If you like this guide, I've made it super easy.

Hey, welcome to Dental Digest. This is a podcast with the mission of enabling you to stay on the cutting edge of evidence-based dentistry. And I'm your host, Dr. Melissa Seibert. This is part one of a two-part series with Dr. David Attia, an educator leading the charge in digital and implant dentistry. In this first conversation, we'll explore how technologies like SmileCloud, CBCT segmentation, and facial scanning are transforming multidisciplinary care, giving us the ability to virtually stack data and plan cases with more precision.
Dr. Attia also unpacks biologically-driven concepts that are reshaping the way we think about aesthetics in the anterior zone. Dr. Attia earned his dental degree from Griffith University and went on to complete a postgraduate diploma in orthodontics and dentofacial orthopedics at the City of London Dental School. He then pursued a master's in oral implantology at Goethe University in Frankfurt, focusing his thesis on full-arch implant rehabilitation techniques while serving as a surgical mentor for Australian students.
As a core instructor for the Australian College of Dental Practitioners' graduate diploma of oral implants, Dr. Attia brings a multidisciplinary approach to patient care and actively teaches and mentors dentists in advanced surgical implant techniques.
Dr. Melissa Seibert: We're going to talk all about managing treatment planning and treating implants in the anterior aesthetic zone, which is not nearly the same pathway as the posterior zone. When you are evaluating an anterior case for implant therapy, what role do digital smile design and CBCT integrated planning play in establishing not just osseointegration, but a harmonizing aesthetic outcome?
Dr. David Attia: I think our fundamental principles from when we were doing analog dentistry and implant dentistry as we know it being a restoratively driven treatment still hold true. None of that has changed. We just have better equipment. We just have better tools. We still strive for the same restoratively driven aesthetic outcomes, but utilizing smile design, as you mentioned, as well as digital technology has become somewhat of a game changer.
Things like SmileCloud, in addition to CBCT segmentation, along with utilizing 3D smile principles that we can then export into ready-made provisionals or pickup provisionals has really streamlined the process. For me, the integration in my practice, especially when it comes to multidisciplinary care, has been a game changer.
We're able to do facial scans, CBCT, intraoral scans, align and stack all the data, and then with CBCT segmentation, spit out our surgical guides if we need surgical guides, spit out our partial extraction therapy guides if we're doing partial extraction therapy, and essentially streamline the process before the patients walk in through the door.
Dr. Melissa Seibert: Talk to me about SmileCloud. I don't use it yet, but I've heard amazing things about it. Can you actually walk me through how you're using it?
Dr. David Attia: Patients walk in, we gather all our records. We'll gather a CBCT, an intraoral scan, and a full set of photos. I take 12 standardized extraoral photos in my practice. We take a set of intraoral photos, the standard six orthodontic intraoral photos. If I'm working in the aesthetic zone, I'll take closeups of the anterior segment, retracted, taped together, occlusal views to show contours, et cetera.
When we import our photos into SmileCloud, and oftentimes complement that with a facial scan, I can then go ahead and align the extraoral photos with the intraoral scans. We use a three or four-point alignment process. Then essentially, the STL will align with the facial photo.
Recently they've released SmileCloud Yes. Effectively from one 2D full face photo, you can create an AI segmentation of what the patient will look like talking. Now, if you can execute that dentistry, it's a great tool. If you can't execute that dentistry, it's really sending patients a message that this is what's possible when it may not be possible, particularly if there are biological limitations that have not been taken into consideration.
For me, I've got all that data and I can work on that patient as if they were in my chair, but in a virtual treatment room. I bring in my technician. I bring in my restorative dentist. I bring in my CBCT. I align all the data from everything to pre-op, wax-up, surgical guides. Everything is stacked all in one platform.
Dr. Melissa Seibert: When you're talking about data, you mean taking the STL, the three-dimensional scan from your intraoral scanner, and stacking that on top of the CBCT so everything else is in alignment?
Dr. David Attia: That's exactly what we're talking about, as well as the extraoral photos. You're able to align a 3D intraoral scan with a 2D image. Then I'll factor in the facial scan. The facial scan provides me with a safety net. If the photos weren't taken the correct way or there's an orientation shift, the facial scan helps us proceed in a facially driven manner.
Dr. Melissa Seibert: What are you using for your three-dimensional face scans?
Dr. David Attia: We recently got a RayFace. There are also apps you can use. There's an app called Clone, Q-L-O-N-E, and they've created a dental version. You can export in PLY and STL. If you've got Modjaw, you can then add your Modjaw into that as well, which I think is the next step, particularly with full rehabilitation.
Dr. Melissa Seibert: What are the cases where SmileCloud would be worthwhile versus where you're wasting your money?
Dr. David Attia: I think all aesthetic cases, all rehab cases. If you're working on a single tooth where a patient doesn't really want to do anything with the rest of the teeth, you can get away with using other technology. However, if you're wanting to stack data, see pre-op, provisional, final, tissue changes, integration with CBCT, and segmentation for surgical guides, it's all in one place. It's all in one platform.
We do a lot of multidisciplinary cases now where ortho, perio, restorative, or ortho, perio, surgical are involved. To be able to know exactly where my restorative dentist wants crowns or veneers, and for that to drive my crown lengthening, and for us to stack all this data together, keeps everyone on the same page every step of the way.
Dr. Melissa Seibert: Now that we've talked about it, let's talk about partial extraction therapy.
Dr. David Attia: Partial extraction therapy is, for me, one of the game changers in my clinical practice. I was very lucky in the sense that when I started incorporating partial extraction therapy, we had set protocols. We had a recipe. We had a sequence that needed to be followed to minimize complications and maximize success.
We always say surgery marries pros. With partial extraction therapy, that could not be more true. I've had complications with partial extraction therapy where the catalyst was the prosthetic, partly because I was not in control of the prosthetic. I can do everything that I can in surgery and with provisionalization, but if the final prosthetics are not done correctly, we can end up in hot water really quickly.
In the aesthetic zone, my first go-to will be partial extraction therapy. Adjacent implants, partial extraction therapy. Pontic sites, partial extraction therapy, wherever possible. For me, it means that I'm doing less grafting. I'm providing patients with what we call ultimate preservation. I think preservation is the ultimate form of regeneration.
Dr. Melissa Seibert: Here's my definition of partial extraction therapy, also known as the socket shield technique. Once you lose the tooth, you're going to lose a lot of the bone because the periodontal ligament is one of the sources of the blood supply to the bone. We often see hard tissue defects, which can become particularly problematic in the aesthetic zone. This is a technique where we are intentionally leaving part of the anterior root structure behind. Tell me if I got that correct.
Dr. David Attia: A couple of modifications. Howie Gluckman's definition is that partial extraction therapies are not just one therapy. It's a number of therapies which involve the decoronation of a tooth that is no longer restorable or indicated for extraction, preserving the root either completely or in part so that we preserve the periodontal tissues associated with that tooth or root.
You might preserve the buccal. That's a socket shield. You might preserve the interproximal. That's a proximal shield described by Joseph Kahn. You might preserve the whole root. That's root submergence. So when we talk about partial extraction therapy, we're not just talking about socket shield. We're talking about a range of therapies that are available to us in various clinical scenarios.
An anterior tooth needs to be removed. It is not periodontally involved. There is no PA pathology. The tooth is vital. It's just broken down and decoronated. In this case, we can perform a socket shield, which is retaining the buccal fragment of a root 1.2 to 1.5 or 1 to 1.2 millimeters in thickness with an internal bevel to create restorative space for the prosthetic components, with the apex of the root completely removed and all organic material within the tooth removed.
The tooth can be root canal treated. You can still do partial extraction therapy. The tooth can have chronic periapical pathology. You can perform partial extraction therapy. We know from the literature that immediate implant placement in chronic infected sites works if you clear out the pathology.
One variation is extending the socket shield into the proximal areas. This provides PDL support to the interproximal bony peaks, which subsequently provides blood supply for the overlying papilla. In cases where you have adjacent implants, this is critical.
Sometimes we get cases where you've got an hourglass or type four anterior socket topography where immediate implant placement in conjunction with socket shield is not possible. That brings us to something called the pontic shield. You perform your socket shield technique, but instead of placing the implant immediately because you don't have apical bone, you graft the socket with what we call a pontic shield and come back later after the material has turned over.
If I can preserve, it means that the implant placement becomes a straightforward process. The key in all of these cases in the aesthetic zone is provisionalization. If I can't get primary stability in an immediate implant and I can't at least put a custom healing abutment, the benefit of immediacy is no longer there. The benefit of immediacy is the provisionalization, whether it be a customized healing abutment or a provisional restoration. Preserving the soft tissues is the name of the game when it comes to implants in the aesthetic zone.
