Mechanical analysis of design parameters of bonded bridges. 1. Effect of metal frame thickness and shape on peeling loads

Adhesion Bridges (acid-etched retainers) have many advantages comparing with conventional fixed prosthodontic treatments. Although they have been applied in many clinical cases, the rational guidance for the design of metal framework has not been studied in terms of resistance for pealing loads.In our study, the effect of thickness and shape of metal frameworks were evaluated by comparing pealing strength (maximum loads under pealing test) using Co-Cr alloy frameworks and acrylic resin block for the substitute for the human teeth. In the results, thicker metal framework showed greater pealing resistance and the proximal extension could be the help for increasing pealing strength.

Mechanical properties of various types of dental alloys were evaluated by measuring tensile strength, Vicker's hardness, elongation, 0.2% proof stress and modulus of elasticity. Specimens were made from dental casting alloys, dental alloys for ceramometal, chromium cobalt base metal alloys for casting, and wrought base metal alloys, respectively.It was expected that results of the test reveal the selection criteria of the dental alloys. The followings are the results of this test:1. Heat treatment has effect upon 0.2% proof stress of the alloys, but does not have upon modulus of elasticity. Required Time-Temperature for heat treatment should be obeyed strictly.2. Base metal alloy features high modulus of elasticity and low 0.2% proof stress thus its metal frame needs to be bulky when it is used for long-span bridge or adhesion bridge being subjected by severe occlusal force.3. High-gold dental alloy for ceramometal may not be suitable for long-span bridge.4. Chromium cobalt wrought alloy is suitable for the clasp of removable partial denture. But, care should be taken when the wrought wire is subjected to heat such as soldering. Severe heat treatment lowers 0.2% proof stress.5. The Pt added high gold casting alloy, namely MAX G, has superior 0.2% proof stress and high modulus of elasticity among the gold casting alloys. This indicates that MAX G is suitable for long-span and adhesion bridges.6. The gold alloys for ceramometal, namely TGB 50 and TGB 30, have superior 0.2% proof stress and modulus of elasticity among the gold alloys.

放電爆発法にて表面処理を施した各種金属と接着性レジンの接着強さに関する研究 ＩＩＩ 放電爆発法にて表面処理されたＮｉ‐Ｃｒ系合金と接着性レジン（Ｐａｎａｖｉａ）とのせん断接着強さについて

In the second report, it was found that the adhesion bridges and splints prepared by a method of electrohydraulic wire explosion could be sufficiently applied in clinical cases. In this report, therefore, the methods for promoting the adhesive strength of the adhesive resin (Panavia) to metal base were discussed. And it was examined whether the components of the two Ni-Cr alloys base metal affected of not the adhesive strength.The mean adhesive strengths of Panavia under shear to Ni-Cr alloys were relatively small compared with Super Bond C & B. Furthermore, there was difference in the shear strength between the two Ni-Cr alloys.However, the shear strengths were 110.0-154.3 kg/cm2From these results, it can be seen that the property of Panavia is clinically favourable since it is considered that Panavia has some surpassing features-the thin capsule of 19μ thickness, the easy manipulation, and the low adsorption. And it can be found that the surface treatment by electrohyraulic Ni-Cr wire explosion is clinically favourable irrespective of the compornents of Ni-Cr alloys.

This investigation was made to clarify the factors which had influences upon adhesive strength of the adhesion bridge to the enamel in the clinical conditions. Tension and shear force were applied onto the specimens for measuring the adhesion strength under the various conditions. The results obtained in this study were summarized as follows: 1) Film thickness of the resin and loading of 100 kg repeatedly on the adhesive resin effected onto the adhesive strength of the resin to enamel and Co-Cr dental alloy. The degree of influences varied, depending on the physical properties of the adhesive resin. 2) Even a slight movility in one abutment tooth decreased remarkably the retentive strength of the adhesion bridge. On the contrary, the movility of both abutment teeth increased it slightly. 3) The rotation force produced by applying load to the bucco-lingual direction decreased remarkably the retentive strength of the adhesion bridge compared with the vertical force.

Cast Ring Bridge の臨床 : 臼歯部接着性ブリッジの新しいデザイン

Recently, several designs have been reported for the adhesive bridge preparation for posterior teeth. Most of these designs are usually based on the principle not to grind the teeth. It may be, therefore, considered that the adhesive bridge constructed according to such designs would be liable to fail in service if it is applied to improperly selected cases or the adhesive procedure is inadequately performed. We designed a new type of adhesive bridge for posterior teeth which involves the necessary preparation on the limited region of enamel around the coronals. It was named Cast Ring Bridge. The Cast Ring Bridge was applied to more than 100 cases during 18 months and it was successful for most of the cases except for 2 cases in which the bridge fell off. The design of the Cast Ring Bridge and its applications for several cases in clinics are presented in this report.
