I . Introduction

Poor oral function and detriment to self-esteem can debilitate millions of people who are partially or which are often used to treat this condition , may not completely restore function because of poor fit related to atrophy . As a result , dental implants have been developed to improve aesthetics and the function of mastication . These implants are metallic struts that are surgically [banner_entry_middle]

br placed in the jaw to support a dental prosthesis . Dental implants provide an alternative to the standard removable complete or partial dentures and improve function almost completely (see Olson JW , Dent CD Morris HF , Ochi S . Long-term assessment (5 to 71 months ) of endosseous dental implants placed in the augmented maxillary sinus . Ann Periodontol 2000 5 (1 :152-6

To be a candidate for the dental implant procedure , a patient must have sufficient bone in the maxillary and mandibular alveoli to support these posts . Unfortunately , after a prolonged period of being edentulous , the alveolar ridge that once supported the teeth becomes atrophic and sufficient bone may not be present for implants . To increase the amount of bone in the maxilla , the sinus lift procedure , or subantral augmentation , has been developed . This procedure involves placing bone-graft material in the maxillary sinus to increase the height and width of the alveolus (see Kasabah S , Krug J , Simunek A , et al : Can we predict maxillary sinus perforation ? Acta Med 46 :19 , 2003

The radiographic appearance of the maxilla after the sinus lift procedure is quite unusual because of the altered anatomy and the dense graft situated in the sinus . To radiologists unfamiliar with this technique , the unusual radiographic appearance can be a source of confusion and can be mistaken for osteomas , fibrous dysplasia , tumors and so forth . Because sinus lift has become a common procedure , it is important for radiologists to be familiar with this surgery and the manner in which the maxillary anatomy is altered . Most radiologists interpret routine sinus or head CT scans without knowledge of the dental history of the patient (see Olson JW , Dent CD , Morris HF , Ochi S Long-term assessment (5 to 71 months ) of endosseous dental implants placed in the augmented maxillary sinus . Ann Periodontol 2000 5 (1 :152-6

The objectives of this are to know about Maxillary Sinus Lift and Sinus Graft Surgery and learn about its procedures

II . Background

Augmentation of the maxillary sinus floor is a well documented technique and is generally accepted as a pure implantology procedure to facilitate placement of dental implants in the posterior atrophic maxilla . It was first introduced by Tatum1 and Boyne and James According to Tatum , The procedure consists of the preparation of a top hinge door to the lateral wall of the sinus . The door is luxated with the Schneiderian membrane to horizontal position . The space underneath the lifted door is filled with graft material… [banner_entry_footer]
