Introduction

The dental business’s fast technological developments current a major problem for clinicians. Thankfully, options now exist to assist them navigate this advanced panorama. This text outlines the medical journey from affected person evaluation to closing prosthesis supply, specializing in how digital expertise and a multidisciplinary method can result in optimum outcomes.

Affected person presentation and referral

The affected person, a 73-year-old feminine, was referred for session concerning a full higher denture and a partial decrease denture.

Key findings

• Higher arch: Periodontally compromised with a poor prognosis for all remaining enamel.
• Decrease arch: Retention of enamel Nos. 44, 43, 33, 34, and 37 (Common Tooth Numbering System enamel Nos. 28, 27, 21, 22, and 18) was potential regardless of some pocketing.
• Main concern: The affected person skilled vital discomfort and mobility within the higher anterior enamel, making chewing troublesome.

Referring clinician’s options

• Handle each arches concurrently for higher occlusion.
• Think about interim and closing prostheses.
• Coordinate surgical timing with denture readiness.

Denturist examination and remedy plan dialogue

Throughout preliminary examination, the affected person voiced sturdy opposition to a full higher denture with palatal protection on account of considerations concerning style alteration and discomfort. To handle sufferers’ considerations, we opted for an implant-supported mounted answer (teeth-in-a-day).

The affected person was then referred to Aspen Oral Surgical procedure, the place Maxillofacial Surgeon Dr. Martin Cloutier carried out a radical analysis and deliberate the following procedures:

Surgical intervention

1. Extractions: All maxillary enamel have been extracted.
2. Implant placement: Seven implants have been instantly positioned within the maxilla.
   1. Six implants achieved excessive major stability, enabling speedy perform.
   2. A seventh implant was positioned for potential inclusion within the closing prosthesis.

Rapid same-day conversion

After surgical procedure, I (Andriy Khomyn) carried out the chairside conversion of the All-on-X provisional prosthesis.

Steps

1. Provisional prosthesis: Tailored to the implant positions and secured with Multi-Unit Abutments (MUAs) for speedy perform.
2. Match and performance: Changes have been made to make sure correct match, perform, and esthetics.
3. Occlusal verification: Undue stresses have been minimized to guard the implants throughout therapeutic.
4. Night time guard: A transitional evening guard was supplied to scale back stress on the implants and promote optimum therapeutic.

The speedy answer restored perform and esthetics, tremendously enhancing the affected person’s confidence and luxury through the therapeutic section.

Six-month follow-up

Oral surgeon evaluate and closing torque check: Six months later, the affected person returned to Dr. Cloutier for analysis. He carried out a closing implant torque check to make sure implant integration and stability. The Multi-Unit Abutments (MUAs) have been retorqued to their advisable specs to verify the implant stability earlier than the fabrication of the ultimate prosthesis.

Digital workflow: scanning for the definitive prosthesis

On the identical day, the affected person returned to my workplace for the ultimate prosthesis workflow.

Pre-scan preparation

Short-term prosthesis evaluation: The non permanent mounted provisional was evaluated for match and performance.

Scanning course of utilizing the Shining Aoralscan Elite

A complete scan was carried out to report all anatomical landmarks, together with the palate, residual ridge, implant positions, and opposing arch. 

1. An in depth pre-op scan was carried out earlier than eradicating the non permanent prosthesis. This can be a very important step because the non permanent serves as a blueprint for the ultimate esthetics and occlusion.
   First, the prosthesis is scanned within the affected person’s mouth, adopted by transferring systematically from the anterior enamel to the posterior area on one facet, after which repeating the method on the opposite facet. I guarantee I seize all surfaces — the occlusal, buccal, and palatal. It is very important scan the delicate tissue contours across the prosthesis.

2. Tender tissue and opposing arch scans: After eradicating the non permanent prosthesis, I scanned the higher arch delicate tissues, together with the residual ridges and palate, to seize all anatomical particulars.
   I used clean, regular motions to make sure a whole scan with out gaps or stitching errors, specializing in areas that may immediately work together with the prosthesis for a transparent, detailed scan of the delicate tissue.
   Subsequent the opposing arch is scanned for occlusal alignment (Determine 1).

3. Implant Scan. Correct seating of scan our bodies is essential; even one scan physique that isn’t totally seated can disrupt all the digital workflow (Determine 2).
   First, I scan fiducial (reference) markers. These markers permit the scanning software program to precisely determine and align every implant’s place and orientation, guaranteeing exact digital mapping, which is crucial for implant-supported prosthesis design and fabrication.
   After the fiducial markers, I scan the scan our bodies and surrounding delicate tissue on one facet of the arch, then proceed to scan all remaining scan our bodies on the opposite facet.

4. Subsequent, I carry out the chew registration. We reinsert the non permanent prosthesis, guaranteeing correct seating previous to continuing.
   I ask the affected person to chew into their pure centric occlusion and hold their chew regular. Then, I take advantage of the scanner to seize the buccal surfaces of each arches, beginning on the midline and transferring in direction of the posterior areas on each side. The chew scan should present clear contact factors and alignment; any discrepancies are corrected with changes and rescanning (Determine 3).

Stitching and verification

The scans of the implant positions and delicate tissue have been digitally stitched to create a seamless mannequin.

Pre-op scan integration

The pre-op scan of the non permanent prosthesis was overlaid with the implant scan knowledge to information the ultimate prosthesis design.

I can manually examine the alignment to verify all the things is correct. If corrections are wanted, I can simply handle them at this level.

Lastly, all scan knowledge is exported as STL information and uploaded to Panthera Dental, with particular notes on tissue compression preferences, esthetic necessities, and the reference factors from the pre-op scan.

Ideas

• Take your time with the implant scan our bodies. That is the inspiration of all the case, so precision is vital.
• Make the most of your scanner’s AI to determine gaps or missed areas.
• At all times confirm the alignment of your scans earlier than sending them to the lab. Small errors now may cause main points later.

By following this workflow, I can make sure the prosthesis will match exactly, perform optimally, and meet the affected person’s esthetic expectations. The Shining Aoralscan Elite has grow to be an indispensable instrument in my follow, streamlining the method and enhancing outcomes for advanced implant instances like this one.

Laboratory section

The digital scans have been processed in exocad utilizing the non permanent prosthesis as a information to design the affected person’s closing smile. This method ensured the design mirrored the provisional’s esthetics and performance whereas enhancing tissue adaptation and compression. Two designs have been produced to guage tissue compression, because the intaglio floor of the ultimate shall be completed in extremely polished titanium.

Significance of intaglio floor design

The intaglio floor of the prosthesis (tissue-facing) was fastidiously designed to be flat or barely convex, which is crucial as a result of:

• It minimizes delicate tissue irritation and ensures even stress distribution.
• It reduces the chance of meals entrapment and tissue overgrowth by avoiding concave designs.
• This design promotes more healthy tissue and supplies a greater seal (Determine 4).

Prototyping with 3D printing

Two full-arch prototypes have been printed utilizing Rodin^® Titan resin and have been then used for medical evaluations. This allowed us to:

• Consider match: Verify correct seating on the implants and tissue adaptation.
• Confirm tissue compression: Verify the effectiveness of tissue help with out inflicting discomfort.
• Assess esthetics: Verify the ultimate smile’s look and alignment in relation to the affected person’s facial options.
• Guarantee implant match: Leveraging correct implant scan knowledge ensured that the bar would align completely with the implants, lowering stress and enhancing longevity.
• Information esthetics: The provisional prosthesis’ pre-op scan supplied a roadmap for replicating the specified smile, guaranteeing the affected person’s expectations for look have been met.

Full digital workflow for the manufacturing of the PFB

We have been capable of totally combine the photogrammetry scans from Andriy into our workflow, designing and manufacturing the PFB for his affected person.

The next scans (Figures 5, 6, 7, 8) have been despatched to Panthera as per the required scans to proceed with the design and manufacture of the PFB:

• Tissue scan;
• DESS scanbody;
• Put up-op temp on the mannequin; and
• Put up-op temp off the mannequin.

Utilizing the obtained information and a specialised splitting protocol, Panthera designed the implant bar and overlay with a straight milling line, guaranteeing no undercuts for streamlined manufacturing and exact match. The Panthera Fusion Bar (PFB) workflow gives varied choices when it comes to overlay manufacturing: most select to obtain the overlay’s STL file for in-house milling of their most well-liked materials. Alternatively, the overlay may be milled at Panthera for them — the choice Andriy selected for this case (Figures 9 and 10).

After design completion, Andriy reviewed the case within the on-line 3D Viewer. The bar is proven in relation to the overlay a cross-sectional view permits to see the bar’s dimension and form contained in the overlay, in addition to its place on the delicate tissues. On this case, the bar measured 6 mm at its highest level and three mm at its lowest. Upon Andriy’s approval, the case proceeded to manufacturing (Figures 11 and 12).

Milling and ending

Panthera gives varied choices for manufacturing instances. Andriy opted to have Panthera mill the zirconia. Panthera has additionally despatched the STL overlay to Andriy to mill or print any further overlays if wanted.

The Zirconia overlay was milled with Vita YZ^® ST. Andriy selected preparation A2 for the tooth base shade and Gingiva Gentle Pink (Determine 13 and 14).

The bar was trimmed, polished, and fitted on the mannequin which was printed by Mark Chan for this case.

Panthera gives a number of decisions for the bar end. Andriy selected the sandblast and anodizing choices. This supplies the floor texture advisable for cementation, and the anodizing minimizes the darkish gray titanium displaying by the zirconia overlay (Figures 15 and 16).

The bar and the milled zirconia overlay have been shipped to Andriy for his technician to finish the case (Figures 17 and 18).

Last prosthesis insertion

• Upon receiving the Panthera Fusion Bar, the bar and prosthesis have been evaluated and confirmed for optimum match and performance.
• The ultimate insertion went very easily, with none changes required.
• The decrease solid partial denture was modified to attain perfect chew administration, guaranteeing correct occlusion with the brand new higher prosthesis.
• To guard the implants and keep the occlusion, the affected person was supplied with a tough evening guard.

This workflow maximizes accuracy and effectivity, guaranteeing seamless digital seize, design, and closing prosthesis supply for full-arch implant instances. The graceful insertion of the Panthera Fusion Bar demonstrates the significance of exact scanning and cautious planning in reaching predictable outcomes (Figures 19-22).

Affected person evaluate

Following the process, the affected person shared this evaluate:

“I’m not one for writing opinions. There isn’t something extra I can say that hasn’t already been written in all of the others earlier than this one.

So I’m simply going to say thanks.

Andriy, you and your fantastic employees made a really distressing state of affairs so extremely straightforward. 

I do know it would sound a bit unusual underneath the circumstances, nevertheless it has been enjoyable.

To the individuals studying opinions to probably decide as to which denture clinic to go to — there isn’t a higher than Smile Care Denture Centre.

You may be so happy you probably did.

Thanks once more.”

This heartfelt evaluate displays the optimistic expertise and high quality care supplied all through the method, highlighting the influence of a supportive {and professional} group.

This part highlights the medical journey from affected person evaluation to the ultimate prosthesis supply (Determine 23).
