| Abstract ： | 「緒言」 PMMAレジンは義歯床用材料として, その操作性の良さから日常広く用いられている. このレジン床の補強法として大きい床面積を持つものや床が両側性に渡る場合などには, 強度の向上を図る目的でレジン床内部に金属線を埋入することがある. しかしながら, この方法では義歯破折線が補強線に沿って多発する傾向も見受けられ, この原因のひとつとして補強線とPMMAレジンとが物理的に結合していることや設置方法などが挙げられる. そこで今回, 我々は当教室の松尾らが歯科界に導入したモーダル解析法を用いて金属線に4META即時重合レジンをコーティングしてPMMA床用レジン中に埋入した実験試料について動態観察を行ったので報告する. 「実験装置及び方法」 1. 実験試料 1) 床用材料 (1) 加熱重合型PMMAレジン GC社製クイックアクロン(以下PMMA) (2)加熱重合型接着性レジン サンメディカル社製メタデント(以下METADENT) |

| Abstract ： | Abstract : For the purpose of reinforcement, a metal wire is sometimes placeed in the acrylic resin base of a denture. This method has a drawback : Breakage frequently occurs along the reinforcing wire. It is presumably caused by a simply physical connection between th reinforcing wire and the resin. It is slso attributable to the arrangement of the wire. To delve into the causes of the breakage, we studied relative movement of the resin to the reinforcing wire (we studied dynamic relations between the resin and the reinforcing wire) in the samples below by using a method of modal analysis. Furthermore, breaking tests and resonance frequency tests were performed to examine differences in dynamic movement and bending strenght between the samples. 1. Materials 1) Types of denture base material (1) Heat-curing PMMA resin : Quickacron (hereinafter referred to as PMMA). (2) Metal bonding self-curing resin : Metafast (hereinafter referred to as 4-META). 2) Types of reinforcing wire (1) Wire : manufactured by Nihon Shiken kogyo company (hereinafter referred to as Co). (2) Net : Sankin Net manufactured by Sankin kougyo (hereinafter referred to as NET) (3) Stranded wire : Stainless steel wire used in orthodontic treatment, manufactured by Yamahachi Shizai Kogyo company (hereinafter referred to as Yoli). 3) Samples The samples were fabricated with combinations of the resins and wires of each type given above. (1) 4-META-Co, 4-META-NET, and 4-META-Yoli : these samples were made by embedding each type of wire in PMMA after primary treatment and coating with 4-META (2) METADENT-Co, METADENT-NET, and METADENT-Yoli : these sampleshave a different type of wire in METADENT. (3) PMMA-Co, PMMA-NET, and PMMA-Yoli : Each of these three kinds of samples has a different type of wire in PMMA (4) One PMMA and one METADENT were set aside as controls. 2. Results 1) Observation of movement In Mode 1, all the samples showed the bending mode, while in Mode 2 a conmpound mode of bending and twisting was observed in every sample. 2) Breaking tests Differences in strength were notable depending largely on the quality as well as form of the metal rather than on the type of denture base material. 3) Resouance frequency In Model, all the sample had a frequency band of 250Hz, while in Mode 2, 4Khz was common. |
