Case 44: All on 4 maxillary arch- System- Straumann implants

 As i have discussed the pros of an all on 4 implants with immediate loading in my previous cases, I am directly going ahead with a case discussion here. The patient had a history of single maxillary metal based complete denture opposing a natural dentition form 3.5 to 4.5 with an RPD for the posteriors. He did present with a root stump in 4.7 After CBCT analysis, we decided to go in for an all on 4 procedure as the patient was not satisfied with the removable maxillary denture.

The system chosen was Straumann Roxolid SLA active. The entire procedure was carried out under local anesthesia. And the impression copings were splinted using pattern resin and a trayless impression was made with addition silicone. Further jigtrial and  jawrelation followed by try-in was carried out. Final prosthesis was torqued over the multi-unit abutments at 15 NCM as all the abutments were angulated to 15 degree for anteriors and 30 degrees for posteriors.

Screw access holes were closed with teflon followed by flowable composite. and occlusion assessed and adjusted. Further treatment involving extraction of 4.7 with a new cast partial denture for the lower was planned by the GP who referred the case for implants to me.











This case 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
