Iatrogenic injury to the maxillary sinus membrane is a common complication during direct sinus lift procedures.
The most common cause is perforation of the Schneiderian membrane using a tungsten-carbide round bur no.6.
We propose a safe technique in which an acrylic stone trimmer is used to create a window in the maxillary
antrum thereby minimizing the risk of injury to the delicate sinus membrane.

INTRODUCTION
T
he sinus lift procedure was introduced
by Boyne et al1 in early 1980s to
overcome the anatomic limitation and
gain vertical bone height in atrophic
areas of the posterior maxilla to facilitate
placement of dental implants.1,2 This procedure has
significantly contributed towards the application of
the dental implants. Even though sinus membrane
elevation is a relatively safe pre-prosthetic surgical
procedure, there are some potential problems
associated to the technique. The most prevalent
intraoperative complication is iatrogenic perforation
of the Schneiderian membrane (11%-56%).3 The
Schneiderian membrane of the maxillary antrum is a
thin membrane that consists of periosteum covered
with respiratory epithelium, which is delicate,
friable, and easy to perforate. Disruption of sinus
membrane leads to loss of graft material, early
implant failure, and interuption of normal sinus
physiological functions.4,5 The literature shows that
30% of sinus membrane perforation occurs with the

use of rotary instruments and drills before the
membrane is elevated.3 It is very difficult to repair a
tear or perforation in the sinus membrane by
suturing because of its inaccessibility and the friable
nature of the sinus lining membrane.6,7
The main purpose of this report is to demonstrate a new technique in which an antral opening is
created using an acrylic stone trimmer, which is
commonly used for prosthodontic laboratory purposes. This tool helps the clinician perform an
atraumatic and safe sinus lift procedure to augment
the posterior maxillary sinus floor using bovine
bone graft.
CASE REPORT
A 68-year-old woman reported to the Oral &
Maxillofacial Surgery Unit at SRM Dental College,
SRM University, Chennai, India, for implant rehabilitation of the edentulous upper right maxillary
molar region (#1-#4). Radiographic examination
(panoramic view) showed insufficient bony support
as a result of severe alveolar bone resorption and
pneumatization of maxillary sinus. The patient had
no history of medical or surgical contraindications
to undergo the surgical procedure. Therefore, a
lateral sinus lift procedure was planned to augment
the bone in the posterior maxillary sinus with
subsequent placement of root-form dental imJournal of Oral Implantology
