Abstract

A medical implant and a method of implanting a medical implant are disclosed. The medical implant (20) is elongate and for fixation in a patient, and comprises an apical bone anchoring portion (200) for bone apposition, and an unthreaded coronal portion (210), wherein said coronal portion (210) has a length (L2) exceeding or equaling a length (L1) of said apical portion (200), and wherein said apical portion (200) has a maximum outer diameter (D1) that is equal to or larger than a maximum outer diameter (D2) of said coronal portion. In a method of implanting a medical implant, an apical part is affixed in the zygomatic bone, and a coronal part is positioned outside the maxilla in the mucous membrane.

Description

PRIORITY INFORMATION

[0001] This application is a continuation of U.S. patent application Ser. No. 13 / 003,260, filed Mar. 31, 2011, which is the 371 National Phase of PCT / EP2008 / 005585, filed Jul. 9, 2008, the entirety of which is hereby incorporated by reference herein.FIELD OF THE INVENTION

[0002] This invention pertains in general to the field of medical implants and methods for implantation of such implants. In particular, the invention relates to dental implants and methods for their implantation.BACKGROUND OF THE INVENTION

[0003] Various types of medical implants are known, e.g. as anchoring elements that are intended to be implanted in patients' jaws. Upon implantation these anchoring elements support e.g. dental restorations via a connection interface.

[0004] Due to various reasons, such as diseases, bone quality may be poor in certain bone regions of a patient. In edentulous or partly edentulous patients jaw bone tissue may be highly resorbed. Therefore it may be difficult or impos...
