In the case of single implant placement with immediate implant installing into immediate extraction socket, implant placement at the 3D-ideal position might be hard because of being various socket conditions. The case presentation of thirty-year-old man single implant restoration  with adjacent-anterior tooth movement for failing to installing the implant at 3D-ideal position is indicated below. The minor orthodontic recovery was simply performed with tooth separation elastics . Immediate implant installing into immediate extraction socket with autogenious bone graft. The socket was closed by palatal pedicle flap moved from palatal mucosa.   Only narrow space was available between single implant head and the medial tooth at second surgery. Separation elastic was used for proper space gaining. Healing abutment was replaced by provisional single restoration.  Separation elastics was used continuously. Proper space was gained for restoration for adjacen...

We would like to show our impression technique through our clinical case for implant-supported fixed partial denture (IS-FPD) with long inter-implant distance. Forty year-old female patient visited initially in 2004 for oral implant treatment. The impression method is indicated below. The points were that: 1. Reliable connections for each impression coping without deformation 2. Preparation in the study model before the impression. 3. Preparation of customized tray. 4. Enough rest time (about a day) for PVS impression material after the impression taking. Implants were placed at pemaxilla and pterygoid region in the maxilla in 2004. Provisional restorati remained palatal resin for resisting against distosional force was fabricated. Reinforced resin stick and plate were made for precise impression taking before the impression for IS-FPD with long inter-implant distance. The view before polyvinyl silicone impression. The impression was completed. Fron...

The case on fully edentulous maxilla of 62-year-old female patient received implant surgery with six implants containing two zygoma implants. The author would like to show a converting method from full denture used in healing period to provisional implant supported-fixed partial denture (IS-FPD). CT graphic view in the region of zygoma of the patient before  the second  surgery was performed. Pre-2nd-surgical view of the maxilla. Only palatal tissue conditioner was remained for the place reproducibility. Implants heads were indicated with silicone  material. Each site was hole drilled.  Three point material was remained for the place reproducibility. The implants cylinders were taken in the full denture. Around cylinders were filled with acrylic resin by the chair side setting. Occlusal view of the maxilla after the second surgery with abutments connection. Provisional IS-FPD was placed. Frontal view of the...

Z ygoma implant drills  are now available in two systems; normal and short: via Nobel Biocare Japan. We devised extra-short drilling system of Zygoma Implant for short inter-maxillary case or other needs such as more posterior placement, unnecessarily use with long drills from the beginning  and an other reason. These drills are used for within 40mm of zygoma implants; within 4 2.5mm  actually remitted. The length of these drills are 10mm shorter than existing short drilling system as a whole.  It is considered that c ombinational use of normal and/or short drilling system. Extra-short drill of pilot drill could be unnecessary but useful occasionally. Normal and short length drills are ready for zygoma implant. (From Zygoma Implant Manual, Nobel Biocare Japan, Tokyo Japan.)  From the right side: normal, short and extra-short drills. In the extra-short drills, round drill is marked at the point of 30, 35, 40mm.  T his mark...

A 87 years old female patient visited us for improving oral esthetics. Both lower incisors were replaced Procera all ceramic crowns. Maxillary full denture was renewed. The patient was satisfied with the treatment for esthetics. She looked younger than actual age. I felt teeth changed the mind. Anterior teeth exposure of the lower jaw are increasing with age. Lower anterior tooth become  important for daily esthetics.   ANTI-AGING FROM TOOTH!  87歳女性の患者さんが見た目の改善を求めて来院されたました。下顎の前歯に4本のプロセラオールセラミッククラウンと上顎に特注の総義歯を新製しました。実際の年齢より若くみえました。歯が心を明るく変えてくれたのだと感じました。下顎前歯の露出が年齢とともに増加傾向があります。下顎前歯も日常の審美では重要になります。アンチエイジングはまず歯から始めましょう！ Initial frontal visit. Lower inter-dental space was noticeable. 初診の前方観。下顎前歯間のスペースが目立つ。  After treatment. Black triangles disappeared. 治療後、黒くみえる歯間空隙は消失した。 Smile after treatment. 術後のスマイル Let us see another case. もう一つ症例を見てみましょう。 Restorations in lower anterior teeth increasing her oral esthetics.　ANTIAGING FROM TOOTH! 下顎...

We clinicians have been annoyed by the case of fully or partially failure implants in the edentulous maxilla because of difficulty on later follow-up and other alternatives for recovery.  Sixty seven-year-old  healthy at that time male patient who received the implants supported fixed partial denture (IS-FPD) with eight implants was treated beneath immediate loading approach in the maxilla in 2006. 上顎無歯顎のインプラント症例でインプラントのすべての、あるいは部分的失敗喪失はその後のフォローが難しい場合が多く我々臨床家を悩ませてきた。 提示した症例は男性67歳2006年当時は健康な状態の患者の上顎無歯学に８本のインプラントでクロスアーチのインプラント支持の固定性義歯が装着された。即時負荷の手法で治療が行われた。 Panoramic view of the patient in initial visit in 2006. 2006年時のパノラマX線写真。 Cross-arch IS-FPD was placed with eight implants in the maxilla. クロスアーチのIS-FPDは８本のインプラントに支持された。 Frontal view of the patient after the prosthesis delivery. 補綴装着時前方観。 An implant in right tuber-pterygoid was lost in 2012. After IS-FPD was broken between right lateral incisal region and central inciser, right two implants we...
