Full Mouth Reconstruction for Severe Dental Erosion
This case demonstrates a comprehensive approach to treating severe dental erosion complicated by periodontal involvement. A 68-year-old female patient presented with painful, worn lower teeth caused by chemical erosion from wine and soda consumption. Through multidisciplinary planning involving diagnostic wax-up, crown lengthening, osseous surgery, and full mouth reconstruction with monolithic zirconia crowns, the patient's natural teeth were preserved and function was restored.
Patient Overview
Patient MS is a 68-year-old female who sought treatment for severe dental deterioration affecting her lower teeth. The patient was concerned about progressive tooth wear and wanted to address the problem before the teeth became too compromised to restore. She maintained an active lifestyle and had a busy schedule that required careful treatment planning and phasing.
Chief Complaint
The patient reported that her lower teeth were painful and worn down. She expressed concern about the progressive nature of the wear and stated that she would like to take care of them before they became too small to cap. The pain and visible wear were affecting her quality of life and confidence.
Diagnostic Findings
Clinical examination revealed severe chemical erosion of the dentition resulting from habitual holding of wine and soda in the mouth. The erosion had caused significant loss of tooth structure, particularly affecting the lower teeth. Additionally, the patient presented with periodontal involvement of the teeth due to a large torus and bony exostosis. These anatomical features trapped food around the teeth, creating localized periodontal defects that contributed to the overall deterioration. The combination of chemical erosion and periodontal involvement created a complex clinical situation requiring multidisciplinary treatment planning.
Treatment Options Considered
Three primary treatment options were evaluated for this patient. The first option was complete dentures, which would involve extraction of the remaining dentition and replacement with removable prosthetics. The second option considered was dental implants following extraction of the compromised teeth. The third option was full mouth reconstruction at increased vertical dimension, which would require selective crown lengthening and osseous surgery but would preserve the patient's natural teeth.
Selected Treatment Plan
Full mouth reconstruction with increased vertical dimension was selected as the treatment of choice. This plan was chosen specifically to prevent tooth loss and preserve the patient's natural dentition. The treatment would involve selective crown lengthening and osseous surgery performed by a periodontist, followed by comprehensive restorative treatment to restore function, comfort, and aesthetics. This approach addressed both the erosion damage and the periodontal complications while maintaining the patient's natural tooth roots.
The decision to pursue full mouth reconstruction over removable dentures was based on the superior functional and psychological outcomes associated with fixed restorations. While removable dentures are better than nothing, they are not a good substitute for real teeth. The patient's teeth, though severely compromised, were salvageable with proper planning and multidisciplinary treatment.
Procedures Performed
Treatment began with a comprehensive diagnostic wax-up to visualize the end result and plan the required changes to vertical dimension. This diagnostic phase was critical for determining how much to open the vertical dimension and how much bone would need to be removed to achieve ideal tooth proportions and position.
The periodontist was guided on the specific amount of bone to remove during the crown lengthening and osseous surgery procedures. This collaboration ensured that the surgical phase would create the proper foundation for the final restorations. Communication between the prosthodontist and periodontist was essential to achieve the planned outcome.
Following the surgical phase, provisional acrylic restorations were fabricated based on the diagnostic wax-up. These provisionals were tested, adjusted, and modified until both the patient and doctor approved the aesthetics, function, and comfort. This testing phase allowed refinement of the treatment before final restoration fabrication.
Once the provisional phase confirmed the treatment design, final cementation of the permanent restorations was completed, restoring the full arch with fixed crowns.
Materials and Technologies Used
Since the patient specifically desired a bleached, non-translucent appearance, monolithic zirconia crowns without layering were selected for the final restorations. Monolithic zirconia provided the strength necessary for full coverage crowns while delivering the bright, opaque aesthetic the patient requested. The material choice eliminated the risk of chipping associated with layered restorations while providing durability and the desired cosmetic result.
Clinical Challenges
Despite the complexity of the case, all phases of treatment proceeded very smoothly. The various treatment phases were carefully planned and scheduled around the patient's busy lifestyle. The collaborative approach between the prosthodontist and periodontist, combined with thorough diagnostic planning and provisional testing, allowed the treatment to progress without significant complications.
Final Outcome
The patient was pleased with the improved aesthetics, function, and comfort achieved through the full mouth reconstruction. The treatment successfully eliminated the pain she had experienced and restored proper tooth contours and vertical dimension. She reported receiving numerous compliments from friends and neighbors who commented on her improved smile, with some expressing interest in having their own teeth bleached.
The full mouth reconstruction with monolithic zirconia crowns successfully preserved the patient's natural teeth and resolved both the pain and wear issues caused by the severe chemical erosion and periodontal involvement. Function was fully restored, allowing the patient to eat comfortably and speak normally.
An important secondary benefit of the treatment process was patient education. By discovering and discussing the etiology of the erosion, the patient became aware of the destructive habits that had caused the damage. This awareness helped the patient avoid continuing behaviors that could compromise the longevity of the restorations.
Clinical Lesson for Other Dentists
This case demonstrates that complex, multidisciplinary treatment can lead to life-changing outcomes when no other good option exists. Understanding that preservation of natural teeth is possible in cases of severe erosion requires specialty training in prosthodontics. Determining how much to open vertical dimension and how much bone to remove to achieve ideal tooth proportions requires experience with diagnostic wax-ups performed with the end result in mind.
Other specialists may not know where to start planning a case of this complexity. The prosthodontic approach involves comprehensive diagnosis, detailed planning with the final outcome visualized from the beginning, and coordination with other specialists such as periodontists who provide clinical crown lengthening. This multidisciplinary approach is essential to successfully execute treatment of this nature.
Additionally, discovering and addressing the etiology of dental destruction can make patients aware of habits to avoid, which is crucial for long-term treatment success. In this case, educating the patient about the damaging effects of holding acidic beverages in the mouth was as important as the technical aspects of the restoration.

Frequently Asked Questions
What causes severe dental erosion from beverages like wine and soda?
Dental erosion occurs when acidic beverages are held in the mouth, allowing the acid to dissolve tooth enamel and underlying tooth structure. Wine and soda are particularly damaging because of their low pH. The habit of holding these beverages in the mouth rather than swallowing them immediately prolongs acid contact with the teeth, leading to severe wear over time. Once patients understand this mechanism, they can modify their habits to protect their teeth or any dental restorations.
Can severely worn teeth be saved, or do they always need to be extracted?
Severely worn teeth can often be saved through full mouth reconstruction when properly planned. Even when teeth appear very short or damaged, techniques such as crown lengthening and osseous surgery can expose more tooth structure and create adequate space for restorations. The key is comprehensive diagnosis and planning with the end result in mind. Prosthodontic training provides the knowledge to determine when teeth can be preserved and what procedures are needed to achieve a successful outcome.
What is involved in opening the vertical dimension during full mouth reconstruction?
Opening vertical dimension means increasing the height between the upper and lower jaws when the teeth are together. When teeth are severely worn, the vertical dimension often collapses, and the jaws close too far together. During reconstruction, the vertical dimension is carefully increased through the design of the new restorations. This requires diagnostic wax-ups to plan the appropriate amount of opening and provisional restorations to test the new dimension before final restorations are made. The process ensures proper function, aesthetics, and comfort.
Why choose monolithic zirconia crowns instead of other materials?
Monolithic zirconia crowns are fabricated from a single piece of zirconia material without layering of porcelain on top. For patients who desire a bright, opaque, bleached appearance, monolithic zirconia delivers excellent aesthetics while providing superior strength. The material eliminates the risk of chipping that can occur with layered restorations where porcelain is bonded to a zirconia core. Monolithic zirconia is particularly well-suited for full mouth reconstructions where durability and consistent aesthetics are priorities.
How does a torus or bony exostosis contribute to periodontal problems?
A torus or bony exostosis is a bony growth that protrudes into the mouth, often along the inside of the lower jaw or the roof of the mouth. When these growths are large, they create areas where food easily becomes trapped around adjacent teeth. The trapped food creates localized areas of inflammation and periodontal breakdown. Osseous surgery can remove or reduce these bony prominences, eliminating the food traps and allowing better access for cleaning. This addresses the periodontal component of complex cases and improves long-term prognosis.
