Prosthodontics
Terenyi Dental Clinic
The field of prosthodontics includes the restoration of severely damaged natural teeth as well as fixed or removable dental restorations designed to replace one or more missing teeth, or even complete tooth loss.
The goal of prosthodontics is to restore missing parts of the teeth or the entirety of the teeth while taking into account your unique preferences and facial harmony to achieve the best possible aesthetic and functional results.
Consequences of Tooth Loss
Dental Veneers
Dental veneers are extremely thin (0.2 – 0.8 mm) ceramic shells crafted with exceptional precision in a dental laboratory and bonded to the outer surface of the teeth.
Thanks to ceramic veneers, we can create a beautiful, aesthetic smile for our patients with minimal loss of natural tooth material.
When Do We Recommend It?
- -When you want to quickly improve the aesthetic appearance of your teeth.
- When you want to permanently change the color of your teeth (e.g., to correct discoloration in root canal-treated teeth).
- To eliminate differences in tooth alignment, gaps, or crowding without orthodontic treatment.
- To address enamel defects or other aesthetic issues.
- To restore damaged or heavily filled teeth.Material of Ceramic Veneers
The material of the veneers is IPS e.max® pressed ceramic, which has ideal physical properties for hardness and can be custom-designed to deliver precise and beautiful results.
Steps of the Procedure:
- Consultation, CT scan, oral examination, and treatment plan.
- Oral hygiene treatment, Guided Biofilm Therapy (GBT).
- Creation of a wax-up or digital model before any preparation begins to better visualize the expected outcome.
- Preparation under local anesthesia.
- Manual or digital impression-taking.
- Temporary veneer applied for the duration of the technical fabrication process.
- Bonding after trial fitting.
- Polishing and follow-up.
- Aftercare: Check-ups every six months, including GBT.
Dental Crown and Bridgework
A dental crown is a protective shell made of artificial material that restores the natural shape, color, and aesthetic appearance of a decayed or damaged tooth by fully covering the tooth's crown.
When Is a Crown Recommended?
- When the tooth is so decayed that it can no longer be restored with a traditional aesthetic filling.
- For the long-term protection of root canal-treated teeth (as root canal-treated teeth are more fragile than vital teeth).
- When the crown portion of the tooth is significantly damaged or partially missing, but the root is intact, allowing the tooth to be saved.
- For aesthetic purposes.
Material of Dental Crowns
Metal-Ceramic Crown/Bridge:
The framework of metal-ceramic crowns is made of metal and covered with ceramic.
While we increasingly strive to create metal-free restorations in our clinic, traditional metal-ceramic restorations made with nickel-free metal alloys are still available due to their excellent price-to-quality ratio and durability.
Advantages:
- Strong and durable, suitable for creating longer bridges.
- Covered with tooth-colored porcelain, providing a natural appearance.
- Designed using CAD-CAM technology, ensuring precise fit and alignment. In modern dentistry, traditional metal-ceramic restorations are increasingly being replaced by CAD-CAM titanium-ceramic restorations and the so-called titanium-frame hybrid bridges.
In modern dentistry, traditional metal-ceramic restorations are increasingly being replaced by CAD-CAM titanium-ceramic restorations and the so-called titanium-frame hybrid bridges.
Disadvantages of Metal-Ceramic Restorations:
- Metal Allergy: Metal-ceramic crowns contain metal, so for patients with confirmed metal allergies, we recommend alternative restorations.
- Appearance: The metal framework gives a grayish tone to the restoration, with low translucency. Additionally, the metal edge may lead to an unfavorable aesthetic appearance at the gumline over time.
- Metal-Free Restorations at Terenyi Clinic:
Metal-free restorations most closely resemble natural teeth. These restorations are made from tissue-friendly materials whose translucency and physical properties are highly similar to natural tooth material. In many cases, even dentists cannot distinguish between a natural tooth and a metal-free crown.
Beyond excellent aesthetic results, another advantage of these biological materials is that they help prevent future gum inflammation and avoid the formation of a dark crown margin. These biocompatible materials are also safe for patients with metal allergies.
Their hardness and tensile strength exceed those of metal-ceramic restorations. Computer-aided (CAD-CAM) design ensures uniquely precise fitting, resulting in exceptionally long-lasting dental restorations.
At Terenyi Clinic, we offer a variety of metal-free restorations. Each type of full-ceramic restoration has its own indication area, so we always select the most suitable option for your individual case to ensure the most beautiful and durable solution.
- Yttrium-reinforced zirconium oxide ceramics
- e-Max lithium disilicate ceramics
- Monolithic / transparent zirconia (Prettau, Prettau Anterior, Procera, Full Contour Zirconia)
- Procera zirconium
For front teeth and individual crowns requiring the highest aesthetic standards, we primarily recommend pressed ceramics or e-Max lithium disilicate crowns.
For bridges and areas subjected to higher stress, we prepare monolithic full-ceramic restorations.
Process for Creating a Dental Crown/Bridge:
- OP/CT Scan, Consultation, and Treatment Plan: Assessing individual needs.
- Preliminary Work: Includes photos, digital scans, study impressions, and shade selection.
- Preparation Under Local Anesthesia: Teeth are prepared as needed; this may include root canal treatment or placing a post structure if a significant portion of the tooth is missing.
- Taking Impressions: Impressions are made, and the bite relationship of the jaws is recorded. If necessary, facial arch registration and pin-point testing are performed.
- Impression Technique: Impressions can be taken using traditional manual methods.
- Temporary Crown/Bridge: While the final restoration is being fabricated (approximately 7-10 days), a temporary acrylic crown/bridge is created. This provides aesthetic appearance and protects the prepared tooth surface from external effects.
Replacement of an Old, Poorly Fitting Crown is Necessary if the Patient:
- Complains of unpleasant odor or taste under the crown.
- Experiences an imprecise seal of the crown edge.
- Finds the crown does not fit correctly in occlusion (too high or too low).
- Has improper contact points with neighboring teeth.
- Seeks replacement for aesthetic reasons.
A dental bridge is a fixed restoration used to replace one or more missing teeth, anchored on the teeth adjacent to the gap. It can be made for natural teeth or implants and, in the case of implants, is secured with screws.
Advantages of a Dental Bridge:
- Quick to complete and delivers a striking aesthetic result.
- Eliminates the gap and restores chewing function.
Disadvantages:
- The teeth adjacent to the gap are subjected to additional load.
- Requires preparation of the teeth bordering the gap.
- Can be difficult to keep clean.
- Over time, the bone and gum in the area of the missing teeth may shrink.
- In terms of material and preparation process, it is the same as for crowns.
Tooth Shaping/Preparation
Tooth preparation is the preparatory process in which the tooth is shaped to accommodate a future crown or bridge. During this process, decayed areas are removed, and sometimes old fillings are replaced with a new structure or reinforced with glass fiber or zirconium posts. At Terenyi Clinic, our doctors use a technique known as shoulder preparation.
In shoulder preparation, a distinct margin is created around the tooth, which serves as a clear boundary for the future crown's placement. This margin is visible during both digital scanning and traditional impressions. The advantages of restorations created with shoulder preparation include precise fitting that does not irritate the gums, reduced susceptibility to decay under the crown, and long-lasting results. This method also helps prevent gum inflammation and recession near the crown edge. During the preparation, only the minimal necessary portion of the tooth is removed, adhering to professional guidelines.
Crowns/Bridges on Implants
Dental restorations made for implants are similar in material and preparation to those made for natural teeth.
At Terenyi Clinic, they are secured using a method known as screw-retained fixation. After being fixed with the appropriate strength, the screw access hole is sealed with an aesthetic filling material, making it virtually unnoticeable. The advantages of this method include the ability for the dentist to remove the restoration at any time without causing damage, as well as the screw-retention process being gentle on the gums.
Partial or Complete Dentures
Removable dentures replace missing teeth and receded gums in cases of partial or complete tooth loss by resting on the gums. They occupy more space in the mouth compared to natural teeth.
At Terenyi Clinic, our primary focus is on fixed restorations secured on implants. However, we also create removable dentures as a temporary solution or, in rare cases, as a permanent restoration option.
Advantages:
- Rapid elimination of tooth loss, quick restoration of aesthetic and chewing functions.
- Elimination of facial sagging.
- Restoration of speech ability.
Depending on the extent, partial or complete dentures can be used to replace missing teeth. The material can be acrylic or metal-based plates. Special elements can be used to attach these dentures to existing natural teeth as part of combined restorations.
Dentures can also be fixed onto implants using ball retention or bar support. Depending on the duration of use, they can be temporary or permanent restorations. Components include: base plate, artificial gums, and artificial teeth.
However, since the base plate and artificial gums take up more space than natural teeth, adjusting to them can be difficult. Due to the continuous shrinkage and changes of the gums, sometimes it is necessary to assist in keeping the denture in place, for example, by using denture adhesives.
