Synopsis presentation/ dentistry dental implants

  1. 1. INDIAN DENTAL ACADEMY Leader in continuing dental education www.indiandentalacademy.com www.indiandentalacademy.com
  2. 2. www.indiandentalacademy.com
  3. 3.  NEED FOR THE STUDY:  Adequate bonding of acrylic resin teeth to denture base is necessary as it increases the strength and durability of the denture since the teeth become an integral part of the prosthesis  In most instances the bonding seems to be satisfactory but still failures do occur www.indiandentalacademy.com
  4. 4. www.indiandentalacademy.com
  5. 5.  The most common type of denture failure occurs between an acrylic resin teeth and the denture base. which may be attributed to a lesser ridge lap surface area available for bonding ,or the direction of stresses encountered during function  Many methods have been experimented to increase the bond strength between teeth and denture like mechanical bonding or chemical bonding www.indiandentalacademy.com
  6. 6.  Gilhereme saavedra etal, studied with Use of a methyl methacrylate –based adhesive on the denture tooth base seems to facilitate increased bond strength of the acrylic resin tooth to the denture base. Water storage and thermo cycling reduced the bond strength of acrylic resin teeth to denture base resin when compared with dry testing conditions. www.indiandentalacademy.com
  7. 7.  J.L.CUNNINGHAM and I.C. BENINGTON studied on the Physical modification and alginate mould seal contamination of the tooth surface had no significant effect on the bond strength.wax contamination of the tooth surface had highly detrimental effect on the bond. www.indiandentalacademy.com
  8. 8.  J.L.CUNNINGHAM and I.C. BENINGTON concluded that A significantly stronger bond was obtained when the resin was packed late in the dough stage, and a superior bond, in all cases, when high impact resin was used. www.indiandentalacademy.com
  9. 9.  J.L.CUNNINGHAM , inferred that The shear bond strength of denture teeth bonded to denture base material can be considerably enhanced by the application of a suitable bonding agent. it can be postulated that the bonding agent increases the Wettability of the tooth surface and may have a solvent effect, which favours a more effective diffusion of the monomers of the denture base polymer into the tooth. www.indiandentalacademy.com
  10. 10.  K.H.CHUNG, C.Y.CHUNG proved that Acrylic tooth surface pre-processed surface treatment with grinding plus sand blasting and processed with a heat-polymerized denture base provided the greatest bond strength between acrylic tooth and denture base. www.indiandentalacademy.com
  11. 11.  The purpose of the study is to check the bonding strength of the acrylic teeth to the denture base after various surface condition methods.  Which tooth will be having maximum strength the one treated with “monomer” or the one in which is surface treated with “silane” coupling agent. www.indiandentalacademy.com
  12. 12.  7.1 SOURCE OF DATA:  The proposed study is an in-vitro study and all the materials will be collected from the market through commercial channels.  96 artificial acrylic posterior teeth (1st pre- molars and 1st molars of mandibular left side) are planed on the ridge lap area up to the cervical region, using a lathe and polished with silicon carbide discs. These specimens are divided into 3 groups of 16 specimens each. www.indiandentalacademy.com
  13. 13.  7.2 METHOD OF COLLECTION OF DATA:  The acrylic teeth are fixed in gypsum blocks with planed ridge lap surfaces exposed. Poly vinyl chloride rings with height 18mm are fixed in the gypsum and filled with molten wax. After de-waxing the planed surfaces are conditioned using materials mentioned above and then acrylised with heat cure acrylic resin. After thermo cycling, they are checked for shear bond strength using an Instron Universal Testing Machine www.indiandentalacademy.com
