Case 18: Two Implant supported manibular overdenture

 Sometimes, we come across patients who never accept a removable dentures and request for some form of fixed or semi-fixed( attachment supported) prosthesis. In this case the patient had adequate bone for a complete implant supported fixed rehabilitation but, economical constraints prevented him from getting it done. Instead he opted for two implant supported overdenture.

After CBCT analysis, I decided to go ahead with the fabrication of complete dentures first, followed by placement of two Standard diameter platform Biohorizon Implants with OD Secure attachments immediately loaded and picked up on to the denture chair side. OD secure attachments are versatile and I personally love their different emergence heights and their sizes.


The entire procedure was done under local anesthesia with a minimal flap exposure only to expose the site where the implants were planned. After the osteotomy completion. paralellism was checked with paralleling pins. Excellent primary stability was achieved and the OD secure abutments were torqued to 30Ncm and the denture was prepared for chair side pick up of the attachment housing.



 OD secure attachment kit normally has 4 different sleeves each of different retentive capacitites. Here since it was an immediate loaded over denture, I decide to choose the pink sleeve which has minimum retentive capacity and safe enough for immediate loading.

After placing the sleeve inside the housing, the complex is placed over the abutment just after placement of the protective ring as shown in the image. This prevents any excess resin to trap under the abutment and protects the site.

Chair side pick up acrylic resin which was auto-polymerising resin was used to pick up the retentive complex over the OD secure attachment. After the acrylic was set, the denture is removed and excess resin is trimmed off and occlusion assessed.

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
