INTRODUCTION
T
he success of an implant is primarily
dependent on the diagnosis of the
preexisting conditions of the patient
and also on the treatment planning.
The essential aspect of treatment planning is proper assessment of an implant site
through examination, palpation, and radiographic
methods. Different radiographic methods have
been used to evaluate the bone quantity and
architecture at the proposed implant site, ranging
from conventional to 3-dimensional models.1 The
assessment of implant sites and their further
evaluation can be enhanced by using radiograph
templates with radio-opaque markers for placement
of implants at proposed implant sites.2-6
Precise and appropriate placement of a dental
implant with proper angulation to achieve desired
esthetic and functional results has always been a
challenge to an implantologist. Implantology is a
multidisciplinary field; therefore, a team approach
between a maxilla-facial surgeon and a prosthodontist is essential in the precise and effective
rehabilitation of the patient. Any communication
gap between the surgeon and prosthodontist leads
to confusion at the time of implant placement
regarding the position or angulation of an implant.
This confusion can make an implant unrestorable,
especially in the anterior maxillary region.7

Position, angulation, implant diameter, and
length of an implant need to be decided before
the surgery is planned. A thorough review of the
literature reveals several techniques of fabrication of
surgical guide stents for the placement of an
implant.3-17 The surgical guide stent described in
the literature cannot (1) guide the drill to the full
depth, (2) give a picture of implant inclination
within bone, (3) indicate the shape of the implant
required in accordance with bone architecture at
the proposed implant site, or (4) help achieve
postrestoration esthetics in immediate restoration
cases. These surgical guides only aid in positioning
of the implant.
Hence, there is a need for an analog technique
to fabricate a surgical guide that allows placement
and restoration of an implant in a precise,
predetermined position and allows esthetic restoration immediately after surgery.
This article describes a technique of fabrication
of a surgical guide stent that enables the surgeon to
maintain the predetermined angulation of an
implant at the proposed site and at the same time
provides information about the implant diameter
and angulation of the abutment required for
esthetic restoration.
PROCEDURE
1. An irreversible hydrocolloid impression is made,
from which a cast is poured into dental stone.
2. Using a pin index system, the removable die of
the proposed implant site is prepared.
3. Bone mapping is done under local anesthesia,
and the distance of insertion into soft tissue is
measured on the labial and lingual aspects of
the alveolar ridge at varying vestibule depths.
