The book starts out with an analysis based on hundreds of examples of the indications and contraindications; a serious attempt is made to offer practitioners the fullest possible guarantees for placing an endo-osseous implant correctly. A preliminary examination is made, on a case by case basis, of the bone structure of the jaw; this examination, carried out scrupulously before the operation, is aimed at establishing the shape of the partially or totally edentulous crests, their width, height and relationship with underlying anatomical structures which must be avoided when making the incision and fitting the blades.
There is a whole chapter on sup-periostal implants. This chapter logically precedes the one on implants extending into the pterygoid process; this is latest proposal for subperiostal skeletal implants, based on the need to ensure stability of the prosthesis “in an upper arch with extensively resorbed bone”.
