A 62-year-old patient came to Yarema Dental with severely damaged teeth in both the upper and lower jaws. For several years, he had been unable to chew hard foods properly, was forced to follow a soft-food diet, and was looking for a fixed solution that could restore his comfort, aesthetics, and confidence.
This was a particularly challenging clinical case because the patient had previously undergone head and neck cancer treatment, including surgery and radiation therapy. After such treatment, dental implant placement requires an especially cautious approach, as the tissues may heal more slowly and any unnecessary surgical intervention can increase the risk of complications.
The Yarema Dental team performed a full-mouth fixed rehabilitation of both jaws using digital treatment planning, guided implant surgery, Straumann BLC dental implants, and permanent monolithic zirconia prostheses.
As a result, the patient regained the ability to chew comfortably, speak with confidence, and smile again.
Initial Clinical Situation
The patient’s primary complaint was the inability to chew solid food properly. Due to extensive tooth destruction, he had been following a soft-food diet for years, significantly affecting his quality of life.
Clinical examination revealed:
- multiple old crowns with recurrent decay;
- root canal-treated teeth with a poor long-term prognosis;
- generalized cervical tooth destruction;
- an unfavorable prognosis for most of the remaining teeth;
- the need for full rehabilitation of both the upper and lower jaws;
- the patient’s desire to receive fixed implant-supported teeth instead of removable dentures.
For this patient, the problem extended far beyond dentistry. The inability to chew normally affected his nutrition, speech, social interactions, appearance, and overall self-confidence.
Why This Case Was Particularly Challenging
Dental implant placement after radiation therapy is far from a routine procedure. Radiation therapy to the head and neck can significantly affect both bone and soft tissues, reducing blood supply, slowing healing, and making tissues more vulnerable to surgical trauma.
For this reason, the treatment strategy focused on:
- minimizing surgical trauma;
- avoiding unnecessary incisions and invasive procedures;
- eliminating the need for bone grafting whenever it could be safely avoided;
- precisely planning the position of every implant before surgery;
- ensuring optimal load distribution across the implants;
- carefully monitoring healing throughout every stage of treatment;
- creating not only an esthetic smile but also a functional and long-lasting prosthetic restoration.
In complex clinical situations like this, success depends not on a single procedure but on the entire treatment workflow—from diagnosis and digital planning to surgical precision, implant selection, prosthetic rehabilitation, and long-term follow-up.
The Yarema Dental Approach: Planning the Final Teeth Before Placing the Implants
In full-mouth rehabilitation, the objective is not simply to place implants wherever bone is available. Each implant must be positioned to properly support the future prosthesis, withstand functional chewing forces, and achieve a natural esthetic outcome.
For this reason, treatment began not with surgery, but with comprehensive digital planning.
The clinical team evaluated:
- cone beam computed tomography (CBCT);
- intraoral digital scans;
- facial and smile photographs;
- lip position;
- the planned tooth shape;
- vertical dimension of occlusion;
- functional loading;
- the possibility of avoiding additional bone augmentation.
The patient’s future smile was first designed digitally. This made it possible to determine the ideal tooth position, shape, and proportions before surgery and to define the exact implant locations required to support the final restoration.
This philosophy is known as prosthetically driven implant planning: the final prosthetic outcome is designed first, and the surgical procedure is then planned to achieve it.
Digital Smile Planning
Digital technologies were used to integrate facial analysis, dental anatomy, and bone morphology into a single three-dimensional treatment plan.
Digital smile planning made it possible to:
- simulate the future smile;
- determine the ideal tooth proportions;
- evaluate tooth position in relation to the lips and facial features;
- balance esthetics with function;
- use the final prosthetic design as the guide for implant placement.
For the patient, this approach provided a clear understanding of the expected outcome before treatment even began.
For the clinical team, it ensured that implant placement was guided by the final prosthetic restoration rather than by bone anatomy alone.
Guided Implant Surgery: Precision for a Complex Clinical Case
Once digital planning was completed, custom surgical guides were fabricated. These patient-specific 3D guides accurately transferred the virtual treatment plan to the surgical field.
Instead of placing implants freehand, the surgical guide ensured that every implant was inserted exactly according to the preplanned position.
In this case, guided implant surgery was particularly important because of the patient’s history of radiation therapy. The more accurately the surgery is planned, the fewer unexpected challenges arise during the procedure.
The advantages of guided surgery included:
- highly accurate implant positioning;
- reduced surgical trauma;
- avoidance of unnecessary bone manipulation;
- predictable placement of temporary prosthetic restorations;
- complete control over the future prosthetic outcome before surgery.
Selection of Straumann BLC Implants
For this rehabilitation, Straumann BLC Roxolid SLActive implants were placed as part of the Straumann® Pro Arch treatment concept.
In this clinical case, the choice of implant system played a crucial role. The treatment required excellent primary implant stability, minimal surgical trauma, and predictable healing despite the patient’s complex medical history.
In the upper jaw, one previously placed and stable implant was preserved, while three additional implants were inserted.
In the lower jaw, four implants were placed. This configuration provided stable support for fixed full-arch restorations in both jaws.
Bone grafting was intentionally avoided. This clinical decision was made to reduce surgical trauma and minimize the potential risks associated with tissue healing following radiation therapy.
Immediate Fixed Temporary Teeth
One of the key stages of treatment was the placement of immediate fixed temporary prostheses following implant surgery.
This meant that the patient did not have to remain without teeth or wear removable dentures during the healing period.
The temporary restorations served several important purposes:
- restoring the appearance of the smile immediately after surgery;
- helping the patient adapt to the new bite;
- shaping the gingival contours;
- improving speech and overall comfort;
- allowing evaluation of the future tooth shape and esthetics;
- providing controlled functional loading during the healing phase.
During the following months, the clinical team closely monitored soft tissue healing, implant stability, occlusion, and the performance of the temporary restorations.
Permanent Zirconia Restorations
Three months after implant placement, osseointegration was carefully evaluated. All implants demonstrated excellent stability, with no signs of inflammation or mobility.
The fabrication of the definitive restorations then began.
To achieve maximum precision, digital scans were taken of:
- the implant positions;
- the healed soft tissue contours;
- the temporary prostheses;
- the patient’s occlusion;
- the final smile design parameters.
The definitive prostheses were fabricated from monolithic zirconia, a material well known for its exceptional strength, durability, and natural esthetics, making it an excellent choice for full-arch implant rehabilitation.
The final restorations featured:
- natural tooth morphology;
- harmonious shade matching;
- individualized pink esthetics for the gingival tissues;
- precise passive fit on the implants;
- balanced distribution of chewing forces;
- long-term comfort and function in everyday life.
Treatment Outcome
Following placement of the definitive restorations, the patient reported a remarkable improvement in his quality of life.
He regained the ability to:
- chew normally again;
- speak more comfortably;
- smile with confidence;
- live without removable dentures;
- feel more comfortable in social situations;
- return to a normal diet without constant restrictions.
This clinical case demonstrates that full-mouth implant rehabilitation can be successfully performed even after cancer treatment and radiation therapy.
However, cases like this require far more than a standard implant protocol. They demand individualized treatment planning, a multidisciplinary approach, advanced digital technologies, and exceptional surgical and prosthetic precision.
Expert Opinion from Yarema Dental
Full-mouth implant rehabilitation involves much more than simply replacing missing or severely damaged teeth. In complex clinical situations, it represents comprehensive medical rehabilitation that must consider bone quality, soft tissue condition, systemic health, occlusion, facial esthetics, and the long-term stability of the treatment outcome.
In this case, the Yarema Dental team combined advanced digital diagnostics, guided implant surgery, Straumann dental implants, immediate fixed provisional restorations, and definitive monolithic zirconia prostheses to restore not only the patient’s teeth but also normal function, comfort, and self-confidence.
For our team, this case illustrates how modern implant dentistry can successfully treat even highly complex patients when every stage of treatment is carefully planned and executed with precision, responsibility, and attention to detail.
Who May Benefit from This Type of Rehabilitation?
A consultation for full-mouth dental implant rehabilitation may be appropriate if you:
- have lost most of your teeth;
- have severely damaged teeth that cannot be predictably restored;
- have old crowns or bridges that no longer function properly;
- experience difficulty chewing food;
