| Abstract|| |
A multidisciplinary approach has often been utilized for esthetic rehabilitation of compromised dentitions. A thorough treatment plan is a prerequisite for achieving longevity in these conditions. This case report describes the management of a case of dental fluorosis with unesthetic gingival contours due to excessive vertical skeletal discrepancy in the maxilla, prognathism of maxillary anterior dentition accompanied with a short upper lip, by surgical intervention, followed by fixed orthodontics, endodontic treatment, gingival reshaping, and final restoration of the maxillary anterior dentition with porcelain restorations.

| Clinical Relevance to Interdisciplinary Dentistry|| |
- This case report highlights the importance of a holistic approach to achieve functionally and esthetically satisfying results when rehabilitating a case of dental fluorosis coupled with anterior vertical maxillary excess.
| Introduction|| |
Endemic fluorosis resulting from high fluoride concentration in groundwater is a public health problem in India. In general, the treatment plan involves an amalgamation of two or more faculties to ensure successful management of such situations. Along with the esthetic reconstruction, the functional harmony is of utmost importance for a definitive treatment outcome.
| Case Report|| |
A 26-year-old female patient complained of a forwardly placed upper jaw and excessive gum display [Figure 1]. Extraoral examination in frontal view showed increased lower face height, lip incompetence, short upper lip, hyperactive mentalis, and full maxillary incisor exposure. The profile view was convex, lips were protrusive, and mentolabial sulcus was deepened. Intraoral examination showed a full complement of teeth, short clinical crowns in relation to maxillary incisors, end-on molar relationships, presence of 5 mm overjet, and 4 mm overbite. Confluent pitting was seen on most of the surfaces of the teeth. A diagnosis of moderate dental fluorosis was made, based on history, clinical findings, and Dean's index.
Radiographic examination involved oral pantomograph showing endodontically treated maxillary incisors and left maxillary and mandibular second molars. Cephalometric analysis revealed dentoalveolar proclination of maxillary and mandibular anterior segments with anterior vertical maxillary excess of 4 mm [Figure 2].
Orthodontic consultation indicated an orthognathic surgery to correct the skeletal excess followed by fixed orthodontic treatment. The patient consent was taken before surgical intervention. Following which, maxillary anterior teeth were built up using composite resin (Ivoclar Vivadent, New York, USA) and the patient was undertaken for conventional fixed orthodontic treatment. Nine months later, the debonding of brackets was done, and the patient was referred for prosthodontic rehabilitation.
The pretreatment photographs and facebow record were made [Figure 3]. The diagnostic wax-up was done, and a silicone index (Aquasil Soft Putty, Dentsply, York, Pennsylvania, USA) was made for fabrication of temporary restorations. Postspace preparation followed by subsequent composite core build-up (ParaCore, Coltene, Ohio, USA) was done. Tooth preparations were carried out ensuring equigingival placement of margins after which temporization of maxillary anterior teeth was performed. The patient was locally anesthetized, and 2 mm of gingivectomy was performed in the maxillary anterior region using diode laser (EZLASE 940, Biolase, California, USA). The gingival margins of the maxillary central incisors and cuspids were kept apical to that of the lateral incisors [Figure 4].
Temporary crowns were taken off and final tooth preparations were carried out. Both cuspids were involved along with the maxillary incisors, and a subgingival finish line was opted for to ensure a natural emergence profile. Final temporization was done, and anterior group function was established along with uniform tooth contact in protrusion. The final wax patterns were carved in accordance with the adjusted temporaries [Figure 5]. The definitive restorations were CAD-CAM processed (Dentcare Zirconia, Kerala, India) [Figure 6].
Final cementation was carried out using resin cement (RelyX U200, 3M ESPE, Bengaluru, Karnataka, India) [Figure 7]. The patient was recalled 3 months later, and facial and dental components of her smile were evaluated [Figure 8] and [Figure 9].

| Discussion|| |
A variety of conditions affect the perception of excessive gingival display. These can be categorized as skeletal, alveolar, muscular, periodontal, and dental in origin.,
It was imperative for the patient to understand that deviation from the ideal was significant and it was difficult to fully remedy the problem. Treatment was undertaken only when the patient had realistic expectations.
The endodontic procedure was carried out, and a strategic establishment of length and angulation of the composite cores was done to make sure that the final crown contours conform to the desired anterior guidance of the restored teeth.
The plan of esthetic crown lengthening via periodontal contouring alone was unacceptable, and it was decided to use periodontal contouring to refine results following surgical intervention. For prosthetic rehabilitation, crown lengthening did contribute to both beauty and function since the stability of new restorations relied heavily on the establishment of adequate coronal retention and a healthy biologic width.
Bone sounding rather than direct visualization was used to determine the osseous morphology as it a more reliable method. The major advantages of laser therapy over traditional scalpel and bur treatment was its ability to induce immediate hemostasis, reduced postoperative pain and better soft-tissue healing.,
A facebow transfer ensured that the incisal plane was aligned parallel to the interpupillary plane. The lips are important as they create the boundaries of the smile, hence we had to seriously consider the correction of the facial composition, before we ventured into the correction of the dental composition.
Fricative sounds helped to determine the labiolingual position and length of the maxillary teeth. The provisional restorations played a crucial role to help confirm proper placement of the final incisal edge position, establishment of anterior guidance and incorporation of long centric. The right canine tip needed to be rounded off approximately 1 mm above the incisal plane to ensure anterior group function in the right excursive movement. Thus for functional purposes a minor esthetic compromise had to be made.
Strict adherence to golden proportion calculations is known to limit creativity and this may lead to cosmetic failure hence creating harmony and balance was done by eye through proper adjustment and evaluation of provisional restorations rather than utilization of any specific formula.
A key feature included in the shaping of the central incisors was the central dominance. Maxillary laterals are known to influence gender characterization, and hence in this particular case, their distal aspect was rounded off. Finally, the canine was shaped to bring out the soft and delicate personality of the patient and thus its labial prominence, and cusp tip was blunted.
For incorporating a youthful appearance, a defined incisal embrasure was established, and polychromatic shades with low chroma and high value were selected.
| Conclusion|| |
This case report demonstrates that the judicious application of oral and maxillofacial surgery, orthodontics and periodontal surgery accompanied by prosthodontic rehabilitation resulted in correction of excessive mucosal display that is predictable and long-lasting.
