Abstract
The SUMICIKON channel saw become available.This method, in which a new saw and an ordinary drill are used together, permits standardized bone channeling.
The only channel bar method of the SUMICIKON's primary fixing situation was better than another blade-vent implant, that some clinical statistics of PERIO TEST reported satisfactory results in clinical use.
And the clinical situation of postoperation is influenced by a good or poor bone channeling.
Then we researched some effects of the inner cooling channel saw. Here is the report concerning the circulation efficiency of cooling water,1)inner cooling saw, 2) outer cooling saw.
The method of examination: We made a piece for experiment, glass plate and metal plate, with channeling hole far insertion. We filled that hole with colored water, used methods 1) and 2), channeling the image at 600 r.p.m. with a low speed engine, filmed the circulation efficiency of the color by the inter cooling channel saw with a CCD (8 mm video) camera, graphically processed this with Macintosh II ci with Raster ops 24 STV(video board), and measured a gray histogram scale with Ultimage 1.4.1.
Result
1. Inner cooling method 0 sec.=37.86 (S.D.=0.91), 1 sec.=40.52(S.D.=1.03), 2 sec.=86.16(S.D.=0.94), 3 sec.=104.95(S.D.=0.96)
2. Outer cooling method 0 sec.=45.96 (S.D.=2.20),1 sec.=37.36(S.D.=2.35),2 sec.=34.90(S.D.=2.06),3 sec.=42.78(S.D.=1.95), 4 sec.=57.51(S.D.=2.18),5 sec.=112.07 (S.D.=1.96) Those results of inner cooling saw method were better than outer cooling method.
