KATO DENTAL CLINIC IMPLANT CENTER HAND DRIVER FOR PREPARATION OF ZYGOMA IMPLANT BED We introduce the hand driver divised by Dr. Satoshi Kato for zygoma implant bed preparation.  The purpose of using the instrument is for precision making the entrance of zygoma in the surgery. The instrument makes sure the entrance of zygoma, which is easy to slip with the mechanical round drill in the surgery.  If the instrument is used, the operation type is not according to conventional Dr. Branemark drill sequences. At first, if the implant trajectory roughly determined in the surgery, the hole of a little bit less 3.5mm diameter hole can be made on the alveolar starting point.  And second, from the sinus window along the implant trajectory that will be placed, sinus membrane could be reflected and pushed to the area of zygoma entrance. With using the hand instrument with round or precision drill, we can make sure the point of entrance of zygoma. And...

Is silicone putty economical for making impression? I try to calculate unit cost for PVS materials with comparison. This is GC PVS putty material. It costs for 7837 yen without tax. The capacity is 278ml + 278m;=556ml. This is PVS injection type and price of 5432 yen/48ml. The unit price of the putty type is 14.1 yen/1ml (0.13 dollar/1ml). The injection type of unit price is 113.2 yen/1ml (1.03 dollar/1ml). 113.2/14.1=8.01. It seem to be eight times of price difference.  It was calculated as 110 Japanese Yen = 1 USA dollar. When we make impression with PVS, it might be nice to use as much putty as possible and as little injection as possible without sacrifice of accuracy.  APPENDIX: This is Zerosil PVS impression material used as our clinical setting. It costs 13570 yen/500ml+500ml=1000ml. The unit price of the material is 13.57yen/1ml (0.123 dollar/1ml) .  The unit price of Zerosil PVS material may be roughly pertinent to th...

katosika.dental We approve the much using of silicone material in taking impression for single implant restoration until now. But we have been looking for any-what good method of economical. We would like to introduce a economical method to make single implant restoration using now. This is a key to use silicon putty around implant copings with little flow silicon material that is used at first to flow onto implant coping. This method allows to save your clinic total silicon cost and time. 1) Preparation of impression copings and per-apical radiographic check. 2) Disposable impression tray that has opened window on the implant abutments. 3) Silicon putty and Poly-venyl silicon material for injection. The impression making starts from pouring PVS flow material onto implant abutment around and waiting until hardening. After the hardening, mixing of putty and puts the putty around the implant abutments and whole tray. Radiographic examination for fitting check between coping an...

https://katosika.dental/ B one graft exposure could be possible although meticulous handling for soft tissue that will be covered. This problem always annoy clinicians. This report describes my experience for recovering of exposure on the graft surface. I don't hope that readers could copy my experiences, my ideas and figures that is showed below as themselves' originals (31th October 2016). Healing of bone graft Incorporating of the grafts happens in concert with a process of initial remodeling and resorption, which is associated with a loss of bone volume. The amount and rate of resorption depends on many factors, such as dimensions of the bone graft, the quality of bone, the quality of the recipient site, biomechanics properties and fixation to surrounding bone. Reviewing the stages of revascularisation and healing bone graft is essential to understand their behaviour and outcome. When the bone graft is first placed the area, the cortical portion of the bone is av...

katosika.dental We approve the much using of silicone material in taking impression for implant bridge until now. But we have been looking for any-what good method of economical. We would like to introduce a economical method using now. This is a key to use silicon putty around implant copings with regular flow silicon material. This method allows to save you total silicon cost and time. 1) Preparation of impression copings with fixing to abutment head of the implants. 2) Impression tray that has opened window on the implant abutments. 3) Silicon putty and Poly-venyl silicon material for injection. The impression taking starts from mixing of putty and puts the putty around the implant abutments. Injection silicone pouring to the tray without window-opening partitioned by a little bid putty. And we seat the tray to the dentition before hardening. The clearance between the abutment putty and the tray might be filled with injection silicon. Abutments side of the  impression...
