We had been difficult to perform impression taking of patients with short inter-maxillary distance. There is an every method of an opened-tray or a closed-tray technique to take impression for screw-retained implant prosthesis (SRIP). We usually prefer to choose an opened-tray method for a point of view of precision. In impression taking for SRIP, there needs a space for impression copings with guide pins and a screw driver. Patients do not always have enough space although short guide pin (SGP) and short screw driver (SSD) can be available. When we use short guide pin, it is not nice to use for the reason being buried under the impression material. In these cases, we use the method for easy access to add the mark on the the head  of guide pin indicated below. The mark help to look for the head of SGP to remove from implant head in taking impression. Implant coping for wide-platform multiunit abutment, regular guide pin and SGP (Branemark system, Nobe...

We would like to introduce sinus membrane elevator nice to use and cheap. Dental cement plugger of daily  clinical setting  is improved to be sinus membrane elevator. And also the price of this instrument is ￥2000 ($20 as 100 yen/ 1 dollar).  Dental cement plugger is an instrument code no. 03-0016 and #14,   YDM Corporation, Tokyo Japan. We always call it "stopper" in our clinic. A cement plugger of our daily clinical setting. Original apex of the instrument. Both lateral side of the apex is cut to be more thiner for easy access to narrow sinus window.  Commercially available sinus instruments. Not always to use these all the instruments in surgery. Live surgery with the instrument. Radiographic view of the patient two years later.

Immediate loading procedure of implants into immediate extraction socket in the upper one side canine to first molar is documented. Forty-eight female patient of smoking habit requested implant therapy with immediate implant insertion and provisional restoration. 上顎左側犬歯から第一第臼歯までの抜歯即時インプラント埋入即時荷重法をドキュメントします。非喫煙者である48歳女性が当院でのインプラント治療を希望した。 Pre-operative occlusal view of the patient.  Live surgery. Post-operative panorama-radiographic view. Healing caps were attached for suture and provisional restoration. Before placement of final implant-supported restoration. Multiunit abutments (Branemark system, Nobel Biocare AB) were seen. Enough mucosal healing around the abutments was observed.  A porcelain fused metal implant-supported fixed partial denture IS-FPD) was  placed three months after the surgery Peri-apcal radiographs in setting of IS-FPD.  

 A female patient of thirty-five years old referred our clinic for implant treatment in the site of upper lateral incisor, which had been fractured. The treatment sequences were indicated below.　 35歳女性が破折した上顎側切歯のインプラント治療を求めて来院した。治療過程を下記に示す。 The tooth extraction and implant insertion immediately. （抜歯と即時インプラント埋入） Minor bone graft.　（骨移植） Immediate provisional restoration.（即時プロビジョナル仮の歯の作製） Final restoration after implant healing period (4~6months) .  （4〜6ヶ月後の最終補綴） Pre-operative frontal view of the patient. Occlusal view. Live surgery Suture with no tension of the flap and immediate implant provisional. Procera custom titanium abutment and all ceramic crown. The titanium abutment in place. Procera all ceramic crown was cemented four months after the surgery. Esthetic smile of the patient was re-established. The peri-apical radiographic view of the patient on final restoration in place.

Ten years and five months of a female patient referred our clinic for orthodontic treatment.  Diagnosis: Class II, lower anterior crowding. Movement period: 24 months.  Retainer: lingual wire bonding lower canine to canine. Implants for orthodontic anchorage were not used for the parental will.  Lower intrusion might be suitable rather than  upper incisors intrusion for future facial esthetics. 初診時10歳５ヶ月女性の患者さんが矯正治療を希望し来院しました。診断は2級下顎前歯叢生でした。動的治療期間は24ヶ月。保定装置は下顎前歯ワイヤー接着による保定。固定用インプラントは患者さんの希望で使用されなかった。上顎前歯の圧下より下顎前歯の圧下が将来のお顔の審美性のためには有効であろう。 Original frontal view of the patient. Incisor crowding was observed in the lower dentition.  Original panoramic view of the patient. There were E-spcae  in the lower  dentition.  Lower incisors intrusion were performed using 020 Australian wire AJ Wilcock . Debonding was done. Good smile was observed after orthodontic movement completion. ...
