Aesthetic Rehabilitation using Feldspathic Veneers
Smile enhancement involves synergy between pink and
white aesthetics. It is very important in complex cases to have
control of each procedure, namely, restorative, surgical and
laboratory, to achieve success in the whole rehabilitation.
The team of clinicians and the technician have many ways
of transforming the soft and the hard tissues predictably.
In this case, a 22-year-old female with an inclination
of the midline and gummy smile wanted to improve it.
Shifting the linear axes of the teeth and correcting the soft
tissues is a delicate procedure that must be very precise.
Initial photos of the patient showing the bilateral asymmetrical line of the gingiva.
In this case clinical crown lengthening was planned in order to resolve the asymmetry of the gingiva followed by full arch bleaching for 3 weeks.
In order to communicate with the patient, a mock up realization can play an important role for
the patient and the clinician to understand and visualize the final result.
The correction of the midline and the linear axes of the teeth can be easily seen in the smile photos after the mock-up procedure.

Enamel preservation is the key to porcelain-veneer success as the bonding in this tooth structure is the most durable. Preparation over the mock up can help reducing only the tooth volume needed for the technician to create thin feldspathic laminates. A special silicon index that allows midfacial visualization simultaneously to incisal reduction control is used to measure clearance from the ideal final shape.
Double cord impression technique was used in this case in combination with PVS impression material.
In order to transfer to the laboratory the horizontal plane and vertical midline of the face, the OneBite® system was used. This system consists of 2 straight bars that lock to each other and an arch.

Wash bake using pure transparent ceramic.
Correction of the opacity in areas where dentine is missing with opaque dentin ceramic.

Final formation of dentin.
Fluorescent dentin. Opaque dentin.
Incisal opalescence. Blueish transparent interproximal.
Mamelons. Fluorescent mamelons.
Final formation of the mamelons. Pure transparent to create dentinoenamel junction.
Final formation of transparency. High value enamel on the line angles.
Luster ceramic on the middle third of the teeth.
Transparent blue to create depth illusion on the middle third of the teeth.
Isolation of the field with rubber dam helped moisture control during the veneer adhesive cementation. After the procedure, the excess cement was removed using a scalpel n.12
Immediately after the rubber dam removal, the tissues are slightly irritated.
Final result lateral views.

It is important for the maintenance of the therapeutic result to provide the patient with a night guard in order to protect the veneers.
In this case, an intraoral digital impression was taken and a splint was fabricated using CAD/CAM technology without any analog procedures.
Nondas Vlachopoulos was born in Toronto, Canada.
He graduated from the school of dental technology in 1985.
He then acquired a BSc Hons from the School of Dental Technology of
the Technological Educational Institution of Athens (1989).
In 1990, he established his own dental laboratory "AestheticLab" in
Athens. Since 2001, he has been Opinion Leader for Noritake Dental,
Ivoclar Vivadent and MPF Brush Co. in Greece.
Since May 2014, he has been an editorial reviewer at the AACD’s
Journal of Cosmetic Dentistry (jCD).
He specializes in aesthetic all-ceramic and implant restorations.
His laboratory collaborates with the Dental School of the National
and Kapodistrian University of Athens, Greece and its postgraduate
programs of Dental Prosthodontics and Dental Surgery, as well as
with the Department of Prosthodontics of the Eastman Institute of
Oral Health of the University of Rochester, USA.
Since September 2015, he has been cooperating with the practical
education of the Postgraduate program leading to a Master of Science
Degree in Dental Biomaterials/Materials of Dental Technology.
The program is operated by The Department of Dental Technology of
the Technological Institution of Athens in conjunction with the Dental
School of the National & Kapodistrian University of Athens.
Nondas Vlachopoulos is leading many educational hands-on courses
in Greece and worldwide (USA, South America, Europe,
Asia and Middle East). He is invited to lecture on dental aesthetics at
international meetings and congresses. He has published articles
in Greek and international Dental Technology journals.
Dimitrios Spagopoulos graduated as a dentist from the University of
Athens. In 2013 he continued his studies in the postgraduate program
of Operative dentistry at the University of Athens. At the same time
he has been working in the field of esthetic, restorative and adhesive
dentistry as a private practitioner.
In addition he has presentations in local and international conferences
as well as various articles on the subject of esthetic and restorative
