Elevating A Smile After Orthodontics Using Feldspathic Porcelain Veneers

When a patient desires to elevate their smile after finishing their orthodontic treatment, dental practitioners can depend on restorative materials to help achieve their desired aesthetic goals. Minimal preparation with feldspathic porcelain veneers is an ultra-conservative choice for aesthetic treatment that can enhance the shape and color of teeth. When tooth preservation is the patient's priority, the combination of supportive orthodontics, minimal preparation, and good communication with the dental lab technician is key to accomplishing these aesthetic goals.
CC: “I just finished my Invisalign and hate my smile. They’re straight, but I have translucent, chipped edges. I want white, straight across teeth” This case shows a method in elevating a patient’s smile, by rejuvenating shape and color, using aesthetic principles and materials, when orthodontics alone can’t fulfill a desired result.

Elevating A Smile After Orthodontics Using Feldspathic Porcelain Veneers

Chief Complaint: “I don’t like the gaps between my teeth, and I want to have a beautiful white smile”

Open gingival embrasures, or “black triangles”, are caused by gingival recession, which occurs when the gum recedes away from the teeth. Gingival recession stems from a variety of different factors including, but not limited to, aging, abrasive dental hygiene methods, and gum or bone disease. This issue, no matter the origin, can cause a person to become insecure about their teeth and the overall look of their smile.

Previous dental history included a 5-unit bridge placed on teeth 23-27 which now presented loose and deemed to be no longer acceptable to the patient.

Most recent dental therapy done at NYUCD included newly placed implant crowns on teeth 3, 14, 19 and 30.
A comprehensive treatment plan was established in order to address the patient’s goals/expectations without sacrificing oral function. The treatment plan included feldspathic porcelain veneers on teeth 4-13, 20, 21, 28, 29, extraction of teeth 23/26 and a PFM bridge #22-27.

Laser Gingivectomy and Polychromatic

Gingival symmetry and biologic width play a vital role in the perception of an overall pleasing smile. When planning procedures such as soft tissue crown lengthening, the successful outcome of a direct restoration will be related to the ability of the clinician to control the surgical site. The use of lasers provide benefits that not only enable the dentist to better visualize the site but allows for better control in contouring soft tissue, keeping a harmonious esthetic and functional relationship between the soft tissues of the periodontum and the tooth structure to be restored.

The Effect of Milling and Sintering Methods on the Translucency of Polychromatic Zirconia Ceramics

The purpose of this in-vitro study was to investigate and compare the effects of speed sintering and slow sintering duration on the translucency of zirconium oxide ceramics using ZirCAD MT Multi blocks and discs, and Katana STML blocks and discs via spectrophotometry. The null hypotheses were 1) there was a difference between slow sintering and speed sintering, and 2) there was a difference between the two Zirconium materials in translucency.

Esthetic Rehabilitation of Maxillary Anterior Teeth Using a Minimal Invasive Approach: A Case Report

A 31-year-old male presented for rehabilitation of his missing maxillary central and lateral incisors. The treatment rendered demonstrates the restoration of severely facially-inclined implants in the esthetic zone. The final prosthesis included the fabrication of a multilayered cement-retained zirconia partial denture (FPD) replacing #7-10 teeth with pink porcelain and full coverage crowns on maxillary canines.

The Use of Angulated Screw Abutments in the Esthetic Zone: A Case Report

A 46-year-old male presented for rehabilitation of his maxillary central and lateral incisors. The teeth were periodontally compromised and deemed non-restorable. Extraction of teeth #7-10 was recommended followed by a screw-retained implant-supported fixed dental prosthesis (ISFDP) and crowns on teeth #6 and #11. Inclination of implants #7 and #10 was too facially and did not allow for a conventional screw-retained prosthesis. Thus, this case report describes an alternative design that facilitated the fabrication of a screw-retained ISFPD.

Esthetic Rehabilitation of Maxillary Anterior Teeth

A 50-year-old female presented for replacement of her existing maxillary anterior crowns. Her chief complain was the unnatural appearance of her smile and perception of aged appearance due to the lack of incisal display.
Clinical examination revealed:
-PFM crowns #7-#10, which depicted nonesthetic appearance (axes, shade, form, proportions, texture, etc.)

Optimizing Esthetics and Function of Anterior Maxillary Teeth Using Lithium Disilicate Ceramic Restorations:  A Case Report 

45-year-old patient presented with a chief complaint of “I’m not happy with my front teeth appearance. I have fillings on my front teeth, and they have different colors”

  • The patient presented with multiple composite resin restorations, performed due to previous caries and black triangles as a result of history of periodontal disease
  • Patient’s expectation: achieve a natural smile with a higher value and uniform shade of anterior teeth.

A New Beginning: Creating Esthetic Results with Non-Ideal Parameters

As the importance of esthetics continues to become more prevalent in our society, clinicians frequently face the task of creating the seamless smile for their patients. Although it is very easy to say, there are numerous clinical variable that are taken into consideration when addressing a patient’s esthetic complaint. The objective of this case is to exhibit how to manage non-ideal situations while creating an esthetically pleasing smile.
In this case, many factors played a role in the treatment planning process and during treatment. The patient ES in this case presented with lingual tipping of #8, three missing anterior teeth, and an occlusal cant. However, with proper treatment planning, great esthetics can be achieved. FPDs/crown were fabricated using esthetic zirconia and the patient was overjoyed with the final result.
