background and aim . vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. in the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increa...

Ridge atrophy accompanied by the pneumatization of maxillary sinus in the maxillary posterior region may lead to inadequate bone height, thereby precluding implant placement. Therefore, it may be mandatory to perform a sinus membrane elevation procedure and augmentation in the bone. The present study aimed to introduce a novel modification method for sinus floor elevation using a gelatin sponge...

The extraction of posterior teeth and subsequent pneumatization of the maxillary sinus compromises osseointegrated implant placement in the posterior maxilla and necessitates associated surgical procedures like sinus floor elevation (sinus lift) and maxillary ridge augmentation. Sinus lift and bone grafting is the procedure of choice when the crestal bone height (CBH) is less than the shortest ...

In the midto late Seventies, Tatum (1977) reported on a procedure of sinus elevation to enable dental implants to be placed in the maxilla where insufficient bone was present due to sinus enlargement. Clinically, this procedure has shown some promise. To date, Lozada and James (1988) have been able to report on tissue recovered with a trephine from a sinus elevation site at the time of implant ...

Implant placement in the posterior maxilla often requires elevation of the sinus floor, which can be achieved through either the modified Caldwell-Luc or the crestal osteotome technique. The objectives of this study were to evaluate (a) the resistance to perforation of maxillary sinus membranes obtained from formaldehyde-fixed cadavers in vitro, (b) the frequency and extent of membrane perforat...

BACKGROUND Various techniques are available for elevating the sinus membrane. The aim of this study is to evaluate three methods of indirect sinus floor elevation regarding elevation heights of 7 mm on the outcomes of membrane perforation, length of perforation, and time required to perform the procedure. METHODS Three different methods for indirect sinus lifting, bone added osteotome sinus f...

A transalveolar approach for sinus floor elevation with subsequent placement of dental implants was first suggested by Tatum in 1986. In 1994, Summers described a different transalveolar approach using a set of tapered osteotomes with increasing diameters. The transalveolar approach of sinus floor elevation, also referred to as 'osteotome sinus floor elevation', the 'Summers technique' or the '...
