Dental Erasmus in Geneve


Last year I made a good decision: Erasmus!
If you have the opportunity I recomend you to live the experience. 

The most dificult thing in Geneva is to find a place to live because it is very expensive. I was lucky to be accepted in one of the residences: cité universitaire de Genève. My advise is to check very early and respect all their information and once you have the OK, you accept. With the new building D, it is easier to be accepted but anyway is very difficult.

There are basically two air companies that flies from Barcelona to Geneva (Switzerland): easyjet and swiss air. If you flight back and forth from geneva it's more expensive than bcn-gva. 






This is a picture of the university dental clinic that is divided in 3 floors:
  • 1rst floor: restauration and endodontics
  • 2nd floor: prosthodontics
  • 3rd floor: periodontics and orthodontics. 





 
Technologies that I could enjoy being in Switzerland:

  • RESEARCH LABORATORY



  • MICROSCOPY AND LASER


I am also happy to enjoy the holidays in Geneva, like "la fête de l'Escalade"  (December 12th)


Here there is some pictures that I like: the view form my room. Le mont Salève!!




Time to go..... 
If you have any question don't doubt to ask me ;)

Dental Veneers

I know it's  been a long time since my last post. But here I am enjoying of my first day of vacation. A long time ago I did a rotation program at school, we had to do some laboratory work for the teacher. What I did is:
1. I did a copy of a dental cast
2. I destroyed some teeth 
3. I build it up with green wax 





After recontructing the teeth, the teacher ask me to make a copy of that and prepare the case for veneers. 
At first I took a look on internet and I concluded some ideas of veneers. 

It is thin slices of porcelain that cover the buccal of the anterior teeth.
Other names:

  • Porcelain laminate veneers
  • Porcelain veneers
  • Horn lamellae


The discoverers were:

  • Buonocuore 50s
  • Rochette 60s
  • Bowen and Simonsen 80s


Materials:

  • Conventional feldspathic porcelain (ideal, more aesthetic)
  • Leucite-injecte reinforced feldspathic porcelain 
    • More rigid
    • Empress (representative system)
  • Aluminous Porcelain processed by computer.
    • CEVEC, Celay, procera.
    • More resistant and opaque
    • Not as much adhesion as feldspathic
  • Polymers or resins
Indications:
  • Color anomalies
    • Amelogenesis (Although isn't the most indicated)
    • tetracyclines
    • Fluorosis
    • stains
  • Form alterations
    • Microdontia
    • Convert the canine into lateral incisor (agenesis)
  • Abnormal structure or texture
    • Dysplasia
    • Abrasions
    • Coronary fractures 
  • Malpositions
    • Rotations
    • abnormal angulatio
  • Diastemas
It isn't indicated in this cases:
  • Inadequate Enamel (minimum 50%)
  • Margins outside of the enamel
  • devitalized teeth
  • Small clinical crown
  • Teeth with cavities or fillings
  • Poor oral hygiene
  • Erupting teeth
  • Fractures involving more than 2/3 coronal
  • Severe stains or bad habits such as:
    • bruxism 
    • onychophagia
  • Inadequate Occlusion 
  • Important Malposition 
Once we have all the necessary information, we can explain to the patient if he wants the veneers. First of all we have to do a diagnostic wax. It is like important to prepare the case. Here we have the cast copy. 



1) 3 Buccal horizontal guide grooves 0.3-0.4mm
the the TFC1 Touatti guide, TFC2 drills.


2) Vestibular reduction 
We mark with pencil to reduce not longer than desired.
Respecting the 2 planes with cylindrical cutter.
Average reduction of 0.5mm (0.7-0.8mm 0.6-0.7mm incisal and medial)
0.3mm Margin  chamfer
Reaching invisible areas without touching contact points

Tooth Extraction

Patient:  X.V
Age: 50
Diagnostic:
     - Partial edentulism 
     - Periodontal disease  
     - Calculum supragingival and subgingival

Our patient has:

   - Superior arch: second right molar, both canines and lateral incisors all with big restorations. Plus a partial superior prosthesis supported by the fractured canine and the molar.
   - Lower arch: the patient has in relative good condition from the first right premolar to the second left premolar and no prosthesis.   


Treatment plan:
- First phase: hygienic phase. We proceeded to do a tartrectomy.
- Second phase: Surgical phase. We removed the superior left canine (2.3) that had a crown fracture. 
- Third phase: prosthodontic phase. Reemplace missing tooth. For now the patient don't want to do the lower prosthesis because she can't afford it. We are waiting if one day is ready.
