Case Report

A 23-year-old female patient presented to our practice with a concern of a discolored anterior tooth and also complained of proclination in her anterior teeth even after orthodontic correction.

On examination

Discolored 11 with no pain, sensitivity and tenderness.
Proclined maxillary anterior teeth and spacing between 21 & 22.
Low frenum attachment.

*Figures 1 to 6 Pre-operative images showing discoloration of 11 and proclined anterior teeth showing spacing with 11,12 and 21,22.*

Radiographic examination was done for 11 which indicated a periodical radiolucency.

After the complete examination, patient was explained about the various treatment options, the number of visits required and the finances involved. She was also informed about her gingival and frenum positioning and a need to undergo additional procedures of laser assisted frenectomy and gingivoplasty to correct the gingival zenith. Initially patient was reluctant about the entire procedure, however after proper counselling with visual aids, agreed to go ahead with the treatment.

Treatment plan

Complete oral prophylaxis
Root canal procedure for 11 followed by a zirconia layered with ceramic crown
Frenectomy and gingivectomy for correction of gingival zenith
Lithium di-silicate veneers with 12,21,22 and added enameloplasty with 13

Procedure Summary

According to the plan, a thorough oral prophylaxis was done.
The discolored tooth (11) shade (A3) was recorded for further comparison using VITA classic shade guide. The adjacent natural tooth shade was also recorded (B1).

*Figure 7 Shade selection of discolored teeth; Figure 8 shade selection of adjacent tooth with the help of VITApan classic shade guide and gray card for color balance.*

Impressions and wax mockups were made, ready to give the patient an idea of the end result through the trial run. Patient was quite impressed with the result and decided to go forward with the treatment.

As planned 11 was treated endodontically.
The laser assisted correction of the gingival zenith and low frenum attachment was performed.

*Figures 11,12 Laser frenectomy and gingival zenith correction followed by planned RCT with 11, intentional RCT with 21 and teeth preparation of 11, 12, 21, 22.*

Tooth preparation was done for 11, 12, 21, 22, while doing the preparation there was a need for an intentional RCT in 21 to compensate for the proclination.
This was followed up giving a set of temporaries on the prepared teeth using Protemp 4. Patient was very happy with the idea of what the final outcome would be.
As planned, the Zirconia layered with ceramic crown for 11 and Lithium Disilicate veneers for 12, 21, and 22 were received from the lab, which were then tried out intraorally.

*Figures 13-16 The lab work received Lithium disilicate veneers with 12, 21, 22 & 11 zirconia layered with ceramic.*

After a satisfactory trial, the prosthesis were made ready for cementation.
Zirconia crown was cleaned with Ivoclean (Ivoclar) for 20 seconds and rinsed thoroughly with water. Silane coupling agent (MonobondPlus, Ivoclar) was applied and allowed to air dry for 60 seconds, followed by application of a dual cure bonding agent (Palifique Universal bond, Tokuyama).
The lithium disilicate veneers were etched with 5% hydrofluoric acid for 20 seconds (Ceramic etching gel, Ivoclar Vivodent) followed by the silane coupling agent (Monobond Plus, Ivoclar) and a dual cure bonding agent (Palifique Universal Bonding agent, Tokuyama).

Meanwhile rubber dam isolation was done; etching was carried out with 37% phosphoric acid for 15-20 seconds; teeth were air dried. A Dual cure bond (Palifique Universal Bonding agent, Tokuyama) was applied. The prosthesis was cemented intraorally using a dual cure adhesive resin cement (RelyX Ultimate adhesive Resin Cement, 3M). The excess was removed after a 5 second tack cure, after which the final curing was completed.
