Definitions
- Figure 8 is an elevational view of yet another alternative embodiment of the invention. Description of the Invention
- Leakage tests were performed over a thirty day period on samples of teeth using various forms of filling materials.
- a split chamber microbial leakage model was used wherein S. mutans or S. faecalis (see groups below), which were placed in the upper chamber, could reach the lower chamber only through the obturated canal.
- a lower chamber consisted of 15 ml of Basal Broth with Phenol Red indicator to which 1 % sucrose was added. The specimens were checked every 24 hours over a period of 30 days for a change in the color of the broth or of the pH indicator from red to yellow (metabolism as acid production), which indicated bacterial leakage.
- Group 7 consisted of fifteen teeth prepared and etched with a self etching primer, followed by application of a root canal sealant, followed by the vertical insertion of resin material (resin percha) in accordance with the invention (NT Resin Percha).
- Groups 8 and 9 were identical to Groups 6 and 7, respectively, except that unlike Groups 1 to 7 that used S. mutans bacteria, Groups 8 and 9 used S. faecalis bacteria. The results are shown in Table 1 below.
- Example 3 A composition comprising polycaprolactone in an amount of about 30%o, caprolactone (methacryloxy)ethyl ester (CMEE) in an amount of about 10%, tricalcium phosphate in an amount of about 30%, and zirconium oxide in an amount of about 10% was manufactured.
- the method of forming the composition involved heating the polycaprolactone (available from Union Carbide) at about 70°C to a softened state. The remaining ingredients were then added and mixed under the action of kneading, pressing, or mixing to blend into the polycaprolactone completely to form a homogenous dough. The formed compound was then ready for application to the carrier device.
- polycaprolactone available from Union Carbide
- compositions from Table 3 above were softened at about 80°C in a convection oven. While the materials were at a workable consistency, they were placed in 15 mm diameter and 1.2 mm thickness steel molds between two glass slides and were cooled down to bench temperature. Sample disks were formed and the glass slides and molds were removed. Some trimming was necessary to remove the flashes from the edge. Five discs were prepared for each test material. The sample disks were then mounted into a cold-cured acrylic mounting material in a splitable cylindrical TEFLONTM mold of a 20 mm diameter and about a 30 mm height, leaving one side of the disk exposed.
- the amount of fibers in the structural component preferably equals at least about 20% by weight (wt %) and preferably about 20 wt % to about 70 wt %.
- Possible reinforcing fibers which are preferably used in accordance with U.S. Pat. Nos. 4,717,341 and 4,894,012 to Goldberg et al.
