    At the Harvard Meeting of 1978 the recommendation was obtained,“Only two kinds, Mandibular Subperiosteal Implant and Blade Vent Implant will be permissible provided they will be practiced based on adequate technology learned and judgment of good common sense and ethics of thought introduced”. However, there are many issues involved by Subperiosteal Implant as well. One of such issues will be the problem of initial fixation. In many cases Subperiosteal Implanting will be applied to Complete Edentulous cases and Multiple Teeth Deficiency cases which will difficult to cure throgh other methods of treatment. For that reason undercut will be less and no initial fixation of frames can be achieved. To cope with the situation there are various kinds of initial fixation countermeasures are reported. Hence, the author has classified and studied such countermeasures.
    1. The method to use metallic screws
    2. Combination use of Intraosseous Implanting to design stabilization.
    3. Method for fixation in which remaining teeth will be utilized to connect frames.
    4. Inner bone system.
    5. Endosseous Subperiosteal Implant.
    6. Method in which the bone undercut will be utilized.

    歯科インプラント体としての多くの欠点を解消するため, 骨親和性に優れた素材であるハイドロキシアパタイト(HAP)をブレード型チタニウムインプラント材に溶射した人工歯根が開発され, 一方, インプラント体植立時の初期固定を強固にし, 長期間顎骨内で安定した維持固定を保持するものとして形状記憶効果をもつTi-Ni合金を素材とするインプラント体が開発されている. さらにTi-Ni合金ブレード型インプラント体にハイドロキシアパタイトを溶射した複合インプラント体が試作されている. 本研究は, このように改良されたインプラント体と周囲組織の変化を組織学的に観察し, 歯科インプラント学領域になんらかの示唆を与えるために行ったものである. 材料および方法 成ニホンザルの下顎臼歯を抜去し抜歯窩の治癒後, 同部位にHAP溶射Ti-Ni合金インプラントを植立し, 同インプラント体頭部を支台とする固定性架工義歯を装着して6か月間機能させた試料を, 軟X線, 光顕および走査電顕によって観察した. また比較検討のため, 下顎小臼歯部にTi-Ni合金インプラント体(形状記憶合金インプラント)を植立, これについても上記と同様に組織学的観察を行った. 実験結果 比較対照に用いたTi-Ni合金インプラント体ならびにHAP溶射インプラント体の表面には海綿骨から増生する新生骨梁が密接し, これとインプラント体の間には線維性結合組織の介在はみられなかった. 密接するインプラント体-骨組織の界面には, 骨組織は溶射層に境界なく移行して化学結合と同様の像を示していた. このインプラント体と新生骨との接着面率はTi-Ni合金インプラントとHAP溶射インプラントのいずれにおいてもインプラント全面積の60%ないし80%であり, 残る40%ないし20%には露出する骨髄腔内の組織が接していた. 本研究に用いたインプラント体は, Ti-Ni合金インプラント体表面にHAPを溶射したものであるが, 形状記憶効果により屈曲変形する部分にはHAP溶射層はなく, 非変形部分には同表面に厚さ100μmのHAP溶射層を有しているので, 一部ではTi-Ni合金が露出した状態となっている. HAP溶射部分では, 化学結合状態で癒合し, 溶射層内には気孔を通して新生骨基質から連続する結合組織線維の侵入がみられた. インプラント体脚部の形状記憶効果により屈曲する部分では, 露出したTi-Ni合金の表面に線維性結合組織が介在することなく骨組織が密接していた. このインプラント体表面に接する骨縁は滑沢で, 骨基質の吸収像はまったく観察されなかった. この部分の新生骨には, 体表面に沿う平行に走る不規則な層板構造が観察された. Ti-Ni合金表面に接する骨組識の界面状態はTi-Ni合金ブレード型インプラント(形状記憶合金インプラント)と酷似した像を示していた. Ti-Ni合金インプラント(形状記憶合金インプラント)との比較検討を含めたHAP 溶射Ti-Ni合金インプラントの組織学的観察結果から, Ti-Ni合金と直接接する部分では新生骨はインプラント体表面に密接し, HAP溶射層と接する部分では新生骨は骨癒合をなすことが判明した. 結論 HAP溶射Ti-Ni合金インプラント体は長期間の機能下でも咀嚼咬合に適応して, 骨内で安定した維持固定が得られるものと推測された.

    A 36-year-old male driver consulted our clinic, complaining the right wrist joint pain on motion. Roentogenographic appearance showed multi-lobulated translucent focus at distal end of the right radius. Initially, curettage and packing with bone cement was performed. Histologically it was diagnosed as giant cell tumor of bone, which consisted of abundant multinucleated giant cells and a few stromal cells.
    Three months later, local recurrence of the right radius and two soft part tumors at the dorsal side of the right hand were found. Soft part tumors were resected and diagnosed as malignant giant cell tumor, which consisted of a few bizarre multinucleated giant cells and dominant proliferation of stromal cells partly arranged in a storiform pattern.
    Seven months after the initial operation, neither recurrence nor metastasis was found. Satisfactory active daily life was gained with moderate limitation of ROM at the right wrist joint and the first MP joint of the right thumb.

    Swift, accurate impression taking of the bone surface is an indispensable requirement for a successful subperiosteal implant. Therefore, the operability and features of various individual tray materials in combination with precision rubber impression materials were compared to establish an ideal impression taking method of the bone surface. The materials and methods employed for the cases were as follows:
    1) Materials for individual tray
    (1) Room temperature curing resin: Ostron 100 (GC)
    (2) Light-activated resin: Eporex Rebase (Nippon Oil& Fats Co., Ltd.)
    (3) Thermoplastic resin 1: Erkoplast (Erkodent)
    (4) Thermoplastic resin 2: heat forming (Shofu Inc.)
    2) Precision Impression Materials
    (1) Polysulfide rubber impression materials (Surflex, GC)
    (2) Vinyl silicone rubber impression materials (Coltex, Yoshida, Exaflex, GC; Express,3M)
    Four subperiosteal implant impression materials (Ostron 100, Eporex Rebase, Erkoplast and heat forming) were applied to the individual tray. As a result, it was found that heat forming was the ideal material from a clinical perspective. This is supported by superior operability without irritation or foul odor, and heat forming properties that allowed for even, sufficient thickness when compared to the other three materials mentioned above.

    Generally, removable partial denture has been clinically employed as prosthetic treatment for defects. However, there are many cases that the patients have not been satisfied with removable partial denture due to troublesomeness of mounting and removal, a sense of incongruity, a lowering of mastication efficiency, etc.
    Dental implanting is one of the means for dissolving such unsatisfaction, by virtue of its feature with which a fixed bridge work can be designed.
    This time, the author reports six Symptomatic cases with blade-vent implants applied to patients having free end defects and are unsatisfied with the denture setting, and one Symptomatic case of subperiosteal implanting which has been applied to a defective example after ceramic implanting.

    This was a clinico pathological and bone morphometric study on several bone graft materials on the antral floor which was elevated from below. Furthermore, the useful application of the mixture of these materials was discussed in the report. Seventeen patients (5 males, 12 females, age; 39~70 y, mean average 56.8 y) were used in this study. The bone substitutes were 4 individual kinds, Interpore®, OsteoGen®, Osteograf®, and Dembone® and mixed groups, 1) Interpore group (Interpore®:OsteoGen®:Dembone®=1:1:1), 2) Osteograf group (Osteograf®:OsteoGen®:Dembone=3:2:2), and 3) Natural teeth as the control group.
    As a result of implantation there was no significant sign of inflammatory reaction around the implants such as gingival redness or puffiness and mobility or percussion sensitivity of the implants.In addition, the pocket depth around the implants was 1 to 2 mm. The success of the sinus lift through implant osteotomy was confirmed at this time. Histopathologically, in the Interpore group, the average was 22.7% bone tissue (new bone 5.5%), 64.5% soft tissue, and 12.8% HA granules, while in the Osteograf group, the average was 13.5% bone tissue (new bone 1.4%), 83.8% soft tissue, and 2.4% HA granules. Therefore, all bone materials were found to maintain adequate bone quantity.

    Denture is constructed for esthetics and masticatory function after the loss of teeth. To obtain good retention and stability, various methods have been introduced. However in clinic, general practitioners encounter many denture cases that are very poor in retention and stability.
    For this reason, the button dentures with intra mucosal inserts have been studied by many implantologists since Dahl introduced it in dental clinic in 1943.But there are few articles about the technique itself and almost no report which studied the change of size and depth of the button hole.
    In this article, the author measured the dimension of the button holes of maxillary mucosa of the patient who had worn a button denture successfully for 8 years, and the following conclusions were obtained;
    1. Button denture must have good occlusal stability.
    2. There were no progressive mucosal inflammation and the inside of button holes were kept clean.
    3. The depth of the botton hole was not changed from 5 to 8 years postoperatively.
    4. There was no changed in diameter of the button holes in premolar region.
    5. The diameter of the button holes became a little larger mesiodistally in the molar region.
    6. The author believes that the button denture reported in this paper will keep pretty good stability and masticatory function for several more years.

    Basically there are two types of blade implants for endoosseous implantation,single-and double-headed, and either is chosen depending on the situation.
    On the presumption that this difference in the number of heads has an impact on the distribution of stress on the alveolar, we conducted stress analysis by photoelasticity examination, which is the most popular,on implants with single-and double-heads where they are planted horizontally and also where the necks are bent 20°. The photoelastic resin and hardener employed for the experiment are Epicoat 828 and triethylene-tetra-amine (TTA) respectively in the ratio of 100:8. The process of hardening was done at 50℃, and the mixture was cooled down slowly, taking four hours.
    In the experiment, single-and double-headed blades were planted in the mixture with the heads horizontal and the necks being bent 20° in the direction of the mesial point, and a vertical weight of 0.20, and 40 kg was given to the blades.From the point of view of practitioners,we report the following findings obtained through this stress analysis.
    From time to time we observe cases with several year histories after implantation in which the necks of metal blades are broken or cracked. Most of them are cases of single-head type, and the damage is often found near the botton of the implants especially when their necks are bent in the direction of the medial point.It can be said that stress is more likely to be concentrated causing fatigue of the metal of single-hended blades.

    In recent years, the utilization of biomaterials has increased and expanded in the dental and oral surgery fields. In many cases, good results could be gained. On the other hand, in a few cases, satisfactory results could not be gained. The implantation of biomaterials, particularly in maxilla, is very difficult and must be done carefully.
    With a few examinations, we report here a case which had received utilization of biomaterials in maxilla and followed by paresthesia of right upper lip, right perimaxillary inflammation and right maxillary sinusitis.

    A purpose of this study is the development of high performance bio-ceramic composite materials, which have excellent mechanical properties and high fracture toughness as several times of characteristics of the human bone. For the purpose, the hydroxyapatite (HAp), which had excellent bio-compatibility and biotic activity, was reinforced by carbon fibers (CF) having bio-adaptability. The microstructures and the mechanical properties were evaluated. The compressive strength of the bio-ceramic composite material manufactured by carbon fiber oxidized for 15 hours (CF-15/HAp) was excellent about 3 times of the of the bone, the Young's modulus was nearly equal to that of the bone and the microstructure showed the strong bonding between HAp and CF. Therefore, this CF-15/HAp composite material was considered to be effective on the utilization as a high performance biomaterial.

    The purpose of this study was to introduce an occlusogram which was 1:1 photographs of dental casts and to apply it in treatment planning and post-operative evaluation for implants. Occlusogram was taken by DSC-618-A PHOTOPET which is very useful in taking occlusograms accurately with gravure film.
    We picked one case out of the latest implanting cases and tried to analyze dental casts by using occlusogram for treatment planning and post-operative evaluation of the implant.
    As a result, the positional relationship of four elements:alveolar ridge, implant, superstructure and opposite teeth were superimposed according to demand and we were able to determine the right position for implant-insertion and to observe the positional relationship of the four elements from occlusal direction.
