Designing smiles and Changing lives with Porcelain Laminate Veneers
Aesthetic dentistry can be life altering for the patient and immensely satisfying for the operating dentist. Understanding the psychology behind why the patient wants a different smile, diagnosing the problems with the existing smile, formulating a treatment plan and finally executing that plan to perfection are a few challenges that the aesthetic dentist faces. Here I present a case of diastema closures with Lithium Disilicate Veneers.
A 28 yr old male patient walked into our dental office saying that he wanted a smile makeover. He covered his face while smiling. There were spaces in the front teeth that he was unhappy about, as he felt that while speaking some saliva slipped out of those spaces. He had budget and time constraints as he was getting ready to see a prospective bride. He needed a solution that would be quick and with less maintenance in the future.
On examination the four maxillary central incisors had diastemata (Pic 1,2) Central incisors were not symmetrical. Existing shade and Gingival zeniths were acceptable and the occlusion was stable.
Orthodontic Treatment to close the diastemata.
Since the central incisors were not symmetrical, even after completion of adult orthodontics, we would need to re-establish central incisor dominance using veneers.
Direct Composite Veneers
A direct approach would let us control the aesthetic outcome with no dependence on a ceramist. Changes if any, could be easily made chairside. But it would mean a lot of chairside time apart from regular polishing and repair that would be needed every 6 months.
Indirect Lithium Disilicate veneers
Lithium Disilicate Veneers could restore the anterior teeth as per the golden proportions. They would need lesser treatment time (as compared to orthodontics), would have more predictable shade stability and lesser post operative appointments in the long term to polish or repair (as compared to direct composites).
Final treatment plan
With the patient’s informed consent, we planned to restore his smile using four Lithium Disilicate Veneers.
An aesthetic mock up was made by the lab [Pic 3]. With the help of a putty index [Pic 4] this was transferred to the patient’s mouth using Bis-Acryl material. The bis-acryl mock-up was bonded, changes were made according to aesthetics and phonetics. The temporary was polished and the patient was sent back home to evaluate the form and function.
We had recalls every week to check if the patient was satisfied with the trial smile and made the required changes till he was satisfied [Pic 5]. Once we got the patient’s go ahead, we recorded the approved smile through an impression [Pic 6]. Then we proceeded with the preparations. We achieved tissue retraction using retraction cords [Pic 7].
The impressions were made in Addition silicone material. The bite was recorded using ALU wax. The patient was temporized again till the next appointment. The trials were checked [Pic 8], textures were marked on the ceramic [Pic 9]. Any interferences in occlusion were eliminated and the trials were sent back to the lab for final glazing. For the bonding appointment all protocols were followed [Pic 10-16]
After completion of bonding, rubber dam sheet was removed [Pic 17] and post-operative instructions were given. One month recall appointment [Pic 18, 19] showed that oral hygiene was good. Patient was following all instructions very well. Most importantly, we found a new confidence in the patient’s smile [Pic 20]
Understanding what the patient’s psychology is extremely important in aesthetic smile makeovers. The dentist, the patient and the ceramist have to work as a team to get the best possible results. We must try our best to achieve minimally invasive dentistry. Keeping the tooth preparations in enamel gives us the best substrate to bond Lithium disilicate with predictability.
