Case 29: Full mouth rehabilitation with Maxillary All on 6 and Mandibular PFM full arch prosthesis

 When the vertical dimension is collapsed and there are no posterior occluding teeth, a re-organised approach is needed to rehabilitate such situations.
A complete protocol involves:
1. Diagnostic impression and Facebow transfer, Centric record.
2. Full arch diagnostic mock up based on Pankey mann Schuyler's technique.
3. Establishing an ideal anterior guidance and occlusal plane restoration
In this case we had to complete the above three steps and then Implant planning was carried out for the maxillary arch which needed extraction of hopeless remaining maxillary teeth.
4. transitional Denture was fabricated after the Implant surgical phase and they were lined with soft-liner
5. After 5 months a hybrid prosthesis was fabricated replicating the occlusal scheme which was done during the planning phase.


The first phase involved the restoration of lower occlusal plane.






Once the lower plane is completed, the next phase involves the placement of 6 implants in the maxillary arch. The surgical phase for this case was carried out by a Surgeon and the case was referred back to me for the completion of the remaining prosthetic full mouth rehabilitation.

So an interim denture was fabricated to maintain the VD and the re-organised occlusion. 
During the Prosthetic phase for the implants, a Hybrid Prosthesis was decided for the maxillary arch, despite explaining the patient the advantages of a Malo-Bridge.
This prosthetic phase for the upper arch involves, placement of healing collars, Trayless splinted impression of the arch, Jig trial, Trial prosthesis and final prosthesis.
In this case there was labial access hole in the prosthesis which could have been prosthetically handle with a Malo bridge. That was a small limitation, however the lip profile made it less significant.










The entire prostheitc phase was done by me at Parasu Dental Hospital.Chennai

Case 45: Cementation protocol for an emax- lithium disilicate crown

Case 45: Cementation protocol for an emax- lithium disilicate crowns The chances for dislodgement of an all ceramic especially a glass ceramic is possible when isolation is not maintained during it cementation. Here is a case with a dislodged emax crown which was done somewhere else a year ago. Bonded restorations normally have an excellent durability and longevity if luted following proper cementation protocols. So what do we do to achieve that protocol? Step 1: Isolate the tooth or teeth using a Heavy rubber dam and use of either Brinker clamps or Tie floss can be done to expose the finish line margin. In this case the margini was supra-gingival and hence a tie-floss technique was employed. Step 2: Treating the cementing surface of the crown. Use of ultrasonics to remove any excess cement flecks attached to the crown is removed. Ideally if u have aluminium oxide air blast it can be used once. Later use 9% or 10% Hydro fluoric acid and etch the glass surface for 90 sec

infective endocarditis & its dental prophylaxis..

Definition Subacute Bacterial Endocarditis (SBE) is a bacterial infection that produces growths on the endocardium (the cells lining the inside of the heart). Subacute bacterial endocarditis usually (but not always) is caused by a viridans streptococci (a type of bacteria); it occurs on damaged valves, and, if untreated, can become fatal within six weeks to a year. Description Endocarditis has traditionally been classified as acute or subacute based upon the pathogenic organism and the clinical presentation. This distinction has become less clear, however, and the less specific term "infective endocarditis" is now more commonly used. Most patients who develop infective endocarditis have underlying cardiac disease, although this is frequently not the case with intravenous drug abusers and hospital-acquired infections. Important factors that determine the clinical presentation are: 1.the nature of the infecting organism 2.whether the infection is superimposed upon preexisting a

Case 50: Full mouth rehabilitation-Digital Dentistry-Digital Smile Design of a patient with Amelogenesis Imperfecta. Amelogenesis imperfecta is a developmental defect where the developement of enamel is affected. The condition may vary from simple white flecks of enamel hypoplasia to severe pitting with brown-yellow discolored teeth. Here is a patient who was a teenager and was emotionally & psychologically affected because of his unesthetic teeth. Reason is, he had amelogenesis imperfecta which was severe involving all his teeth with yellow brown discolorations along with pitting in the posterior teeth. Transforming smile and improving his psychological level can be achieved by first gaining the confidence and trust. This emotional dentistry can be fulfilled by Digital Smile design. As discussed in many of my cases, I use Adobe photoshop for my smile designing part. The very same day the patient walked in, photographs and videos were taken to plan the smile and re-enforce th
