Case 20: Stabilisation splint- Management of TMD pain
Temporo-mandibular joint disorders and its related masticatory muscle pain management is a challenging field on its own. Diagnosis of such cases are very tricky and one might take it for granted and miss the diagnosis if we fail to understand the concept of Occlusion. Referral practise in such situations take an upper hand and its advisable to refer the case to a specialist in TMD management.

This case was giving a history of chronic pain in the pre-auricular region and was having radiating neck and head aches. After a thorough examination of intra-oral and radiographic findings, we proceeded with TMJ and its Muscular assessment.

While doing so the patient had pain on palpation of disto-buccal to hamular notch region in the maxillary arch on one side. This gave us a hint on Pterygoid muscle soreness. Hence to rule out the discomfort caused by the Pterygoid sorenes, which is a major muscle in holding the joint in Centric relation, a stabilisation splint was fabricated immediately.

Within a couple of days the patient's symptoms vanished and then we referred for a thorough assessment with a TMD specialist for further management.



A stabilisation splint will deprogram the mandible and eventually makes the TMJ rest in centric relation. Its a viable treatment in TMD when the cause is related to a muscular origin. The canine guidance ramps in the stabilisation splint puts the least amount of load on to the masticatory muscles with only the temporalis muscle being tested during eccentric motion. In this way the lateral pterygoids which are most commonly affected in such TMD muscular problems will be completely rested and the soreness can be managed immediately.
Once the patient becomes comfortable, further occlusal analysis, facebow transfer and assessment of occlusal interference and need for an occlusal rehab can be planned on a definitive basis.

This case was done by me during my Post graduation.

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
