Porcelain & Composite Veneers - Bonding For Premium Dental Aesthetics

Porcelain Veneers

Premium Smile Enhancement

At Dental Aesthetics Athens, we are specialized in minimally invasive veneers, that should create dramatic and natural smiles. As our core principles highlight minimal invassiveness and structural integrity of healthy teeth, ceramic veneers serve these purposes finely.

Porcelain veneers are regarded the most conservative and aesthetic dental restorations. They restore aesthetics and function even with no tooth reduction / cutting.

 
PORCELAIN VENEERS - SUCCESS CRITERIA

  • Aesthetic enhancement with proper shade selection
  • Matching primary and complementary colour characteristics i.e transparency, opacity, fluor- and opalesence
  • Conservative tooth preparation
  • Functional scheme of occlusion
  • Balanced occlusion to avoid catastrophic fractures
  • 360-veneers on young patients with worn teeth due to grinding or clenching

PORCELAIN VENEERS VS PORCELAIN CROWNS

Up to recently, the only way to correct dental imperfections was to cover the tooth with a crown. However, such restorations are considered invasive nowadays. Therefore, in most cases porcelain veneers are the treatment of choice for any teeth , unless those, which bear crowns already.

In our clinic, each restorative treatment is ignited with and driven by the Aesthetic Analysis and DSD (see:aesthetic analysis). The designed outcome is faithfully transferred on to the natural teeth with the use of navigation indexes soaked with flowable trial composite. So, we are able to show you how the end result may look, and that is directly from the very beginning.

Limitations or contra-indications to ceramic veneers are considered pre-operatively with the Aesthetic&Functional Analysis (i.e. extreme malposition of teeth, need for periodontal therapy, need for additional treatments).

Cornerstone for such conservative, yet premium aesthetic restorations is the ultra durable bonding procedures, that have been introduced the last years

VENEERS - MATERIALS & INDICATIONS

Veneer is a thin layer of restorative material, which is bonded onto the front surface of teeth. Two main types of materials are utilized to fabricate a veneer, composite and dental porcelain (ceramic).

Composite veneers (see: composite veneers) are either intra-orally built-up with layering technique, or extra-orally milled by CAD/CAM setup, and later bonded to teeth. As opposed to composite veneer, its porcelain counterparts can only be indirectly fabricated regularly with CAD/CAM installation.

Major advantage is, that minimal preparation of the tooth (e.g. reduction) is regularly demanded. Most of the cases can be treated in ''no-cut no-drill'' approach.

Most veneer procedures can be carried out without anesthesia.

In heavy discolorations, matching the shade of a sole veneer and blending it into the color of the adjacent teeth sometimes appears problematic, hence pre-treatment with whitening procedures of the dentition is a prerequisite. Thus, minimally invasive tooth preparation can finally be operated.

Typically, a labial 0.3-0.5 mm of tooth reduction/cutting is required for a porcelain veneer.

However, in well selected cases, natural tissues can be fully preserved.

Especially,on retruded teeth no cutting is employed. As a result, treatment can be non-invasive and teeth can remain intact.

Porcelain (ceramic) veneers are also used to resurface teeth such as to make them appear straighter and with a pleasing alignment.

Porcelain veneers demand 2-3 visits.

ADVANTAGES OF PORCELAIN VENEERS AS COMPARED TO SYNTHETIC RESINS

  • New Glass-Ceramics are durable & unlikely to stain. Although in the last years new biomimetic synthetic resins have been produced with outstanding mechanical and optical properties, still porcelain exhibits unrivaled results in the long run.
  • High-Strength Glass-Ceramics can withstand greater forces as opposed to composite synthetic resins , therefore are to be mainly chosen for closing big diastemas
  • If large tooth modifications must be operated, ceramic veneers should be chosen over synthetic resins.
  • Ceramic or Glass-Ceramic veneers are regarded as the most conservative restorations with exquisite optical properties
  • They can produce prosthetic restorations with longevity and high success rates

DRAWBACKS OF PORCELAIN VENEERS IN COMPARISON TO SYNTHETIC RESINS

  • CAD/CAM ceramic ingots are monochromatic
  • Ceramic veneers are not easily repairable,should a catastrophic fracture occur
  • Shade registration and communication employs two operators, clinician and ceramist. Hence, colour re-produce is proven a very sensitive process

ALTERNATIVES TO PORCELAIN VENEERS

On extreme malpositions, orthodontics should primarily be used , or orthodontics followed by veneers.

At Dental Aesthetics we use pressed ceramics e-max (IPS IVOCLAR Inc) and feldspathic porcelain.

Composite Veneers

Premium Dental Aesthetics Can Be Cost-Effective

Composite veneers are minimally invasive restorations and broadly reputed as the direct, cost-effective, same-day technique for smile re-design.

New sophisticated composite veneers feature endurance, mechanical robustness and outstanding aesthetics. Biomimetics is their main property, as they exhibit similar optics, stiffness and elasticity with the natural teeth.

They can predictably repair shape deformities and tooth dis-colorations.

By definition, a composite veneer is a thin layer of synthetic resin, which is placed on the front surface of tooth to either improve appearance, or to comprehensively restore and mask multiple fillings.

Composite veneers can enhance brightness and correct shape of teeth so as to naturally blend with the whole dental synthesis. They harmoniously make up a mostly pleasant, healthier and younger smile.

 
COMPOSITE VENEERS-ADVANTAGES & INDICATIONS

  • They are easily repairable, should a fracture occur.
  • They can be applied in ''Same-day treatment'' approach
  • Mal-positioning of teeth can be corrected with composite veneers
  • They can precisely re-produce colour and size
  • Composite veneers can be used for diastema closure. Small spaces of up to 1.00-1.50mm can be closed with synthetic resins. Larger diastemas should be restored with their ceramic counterparts
  • Restoring the worn dentition. Individuals who clench or grind their teeth appear with shortened teeth resulting in a prematurely aged face. Due to their biomimetic elasticity and their color properties, synthetic resins can restore deformities in a mostly conservative approach
  • They can provide a variety of color, shape and symmetry to facilitate complete matching with any tooth
  • They exhibit good longevity due to fine resistance against shear and tensile forces .They can be finely polished and shined thus sustaining gloss in the long run with normal maintenance in regular re-calls

Design of composite veneers is navigated by appearance and function. Therefore, the intended result is visualized initially and that is prior to teeth preparations.

Limitations to the use of composite veneers can be extreme tooth-malposition, bleeding gums etc

Enrichement with nano-particles optimizes brand-new resins and their optical properties to such an extent , that oftentimes rival ceramics. Therefore, synthetic resins are considered the material of choice for immediate veneers

Cornerstone for such conservative, yet advanced restorations are the brand-new, state-of-the-art bonding agents exhibiting strong adhesion at the interface between tooth and restorative materials

In Dental Aesthetics we use micro-filler composites from Cosmedent Inc. USA and Asteria nano-filler composites by Tokuyama Inc. Japan.

Inlays & Onlays

Aesthetics for the Posterior Teeth

Role of Inlays & Onlays in smile makeovers

In tooth-wear cases inlays and onlays are used to increase the height of the posterior teeth on a fully non-invasive approach, thus facilitating lengthening front teeth.

Even in intact dentitions, onlays can be adhered to the posterior teeth to help provide space for longer front teeth , without compromising (eg drilling) healthy tissues.

Inlays & Onlays - Indications

When a tooth of any of these groups is excessively decayed, damaged or fractured, a direct restoration (a build-up) of conventional composite filling is often not applicable. In such cases, inlays & onlays made of porcelain or synthetic resins support the tissues successfully and with a long-term prognosis. The fabrication of those restorations provide a highly aesthetic outcome along with utmost ideal durability and strength.

The alternatives to such cases would be a crown, or root canal therapy and a post, all considered none-the-less outperformed and over-treating procedures.

Fabrication

Inlays & Onlays are fabricated with a CAD/CAM setup, that means a precise impression of the teeth is taken and the fabrication is custom made for the patient in the dental laboratory, while a temporary is in place.

Sophisticated synthetic resins (ie composites) exhibit outstanding mechanical and aesthetic properties, that almost confront ceramics. They are by default considered material of choice for the fabrication of inlays/onlays, unless contra-indications present.
