- 20. 20 Paraesthesia was found in 2 pt with body # in 2 wk and 1 month Fracture mobility was seen in 32 pt at 2nd week ,and 8 pt in 1 month Implant exposure was present only in 2 pt at 1 month No pain was observed after one month Significant increased in bite force
- 21. 21 Analysis of bite force
- 22. 22 Analysis of bite force condt… This finding correlate with the finding of Ellis and Throckmorton 1994 . Bioresorbable plate in mandibular # was efficacious enough to bear masticatory load during the osteosynthesis of bone.
- 23. 23 Resorbable plates in mandibular fracture is highly appreciating……. 1. Subsequent hydrolysis of plates and screw 2. Better evaluation of fracture healing 3. No need of repeat surgery for hardware removal
- 24. 24 Bell (2006) used bioresorbable plates for pt with mandibular and mid fascial #and found uneventful healing.
- 25. 25 Suronen et al . (1993) treated more than 200 pt with bioresorbable plates successfully and stated that use of bioresorbable fixatation can be consider routine and it will be definitely state of art at the beginning of millennium.
- 26. 26 Bio-resorbable plate have enough strength to bear masticatory force and can be used safely in mandibular fracture . High degree of skill is required . Not to damage the plate by applying too much pressure

Editor's Notes
- Women's demonstration for bread and peace - March the 8th, 1917, International Women's Day (IWD) is celebrated on March 8 every year.[3] It commemorates the movement for women's rights. While the first observance of a Women's Day was held on February 28, Petrograd, Russia February 28, 1909 in New York, March 8 was suggested by the 1910 International Woman's Conference to become an "International Woman's Day." After women gained suffrage in Soviet Russia in 1917, March 8 became a national holiday there. The day was then predominantly celebrated by the socialist movement and communist countries until it was adopted in 1975 by the United Nations.
