THE METHOD FOR CLOSING EXTRACTION SOCKET, PART IV: CLOSING @THE MAXILLARY POSTERIOR REGION 抜歯窩閉鎖法パート IV:  上顎後方部における閉鎖 SPLIT PALATAL FLAP TO CLOSE THE RECIPIENT EXTRACTION SITE スプリット口蓋弁を使用する受容抜歯窩の閉鎖  When we perform immediate implant insertion to the immediate (or delayed) extraction socket, complete closing of the mucosa may be considered to be difficult.  Although several methods of the closing the extraction socket have been proposed, complete closing seems to be difficult clinically.  The method of split palatal flap technique  to close the immediate extraction socket may be  useful for a solution to the problem when the palatal flap is very thin . Advantages of the method are: 1) simple and easy procedures. 2) useful in the  maxillary posterior region that has the thin mucosa. Shortcomings are: 1) extensive flap elevation. 2)  morbidity with flap elevation with split incision such as bleeding. 3) sometim...

Classification of molar extraction sites for immediate dental implant placement: technical note. Smith RB, Tarnow DP. Int J Oral Maxillofac Implants. 2013 May-Jun;28(3):911-6. doi: 10.11607/jomi.2627. Department of Prosthodontics, Columbia University College of Dental Medicine, New York, New York 10155, USA. RSmith@SDNonline.com Dental implants may be successfully placed immediately into fresh extraction sockets when primary implant stability can be attained. This article presents a new classification system for molar extraction sites that describes extraction sockets based upon the bone available within the socket for stabilization of an immediately placed implant. Three categories--types A, B, and C--are employed: the type A socket, which allows for the implant to be placed completely within the septal bone, leaving no gaps between the implant and the socket walls; the type B socket, which has enough septal bone to stab...
