Ref 4333-SinCrest Ø 3.0 - brown colour
Step 0 Gradually screw the device inside the dedicated guide hole.
The device has achieved the depth obtained by means of the drills
when the white mark emerges minimally during the progress of the
probe as compared to the grip (see figure n. 8).
Step 1 Turn the handle anti-clockwise by1/2 revolution and at the
same time implement an axial pressure, start the osteotomy with
"back and forth" turning movements by 1/2 turn until the distance
(0.5mm) between the tooth and the stroke is zero (see figure n. 9).
The SinCrest device has progressed by 0.5 mm in the apical direction.
By manually implementing pressure on the probe (see figure n. 10),
constantly check the residual strength of the maxillary sinus floor.
The progress in the apical direction of the probe shows that the bone
operculum has been fractured; unscrew the SinCrest device and
insert bio-material or directly the dental implant. In case of residual
bone floor strength detected by the probe, proceed to Step 2.
Step 2 Screw by 1/2 turn (each 1/2 turn equals a 0.5 mm progress
of the threaded component) after the tooth is engaged in the stroke
(see figure n. 11) and repeat the steps 1 and 2 until the fracture of the
maxillary sinus floor is reached.
The progress of the depth of the SinCrest device is indicated by the
emergence, as compared to the grip, of the 2mm white mark on the
probe (see figure n. 10).
Ref 4338-SinCrest drill HB Ø 3.2: this drill must be used in case of
hard bone encountered during the screwing stage of the SinCrest Ø
3.0 device. This drill does not require positioning a stop since it must
simply widen the hole without working in depth. The osteotomy may
be resumed by means of the SinCrest Ø 3.0 device. If bone is avail-
able, the surgical procedure may be continued as illustrated in the fol-
lowing steps so as to position a dental implant with a wide diameter.
Ref 4381-SinCrest drill Ø 4.0: the use of this drill must always be pre-
ceded by the SinCrest drill Ø 3.0 and SinCrest drill HB Ø 3.2. This drill
does not require a stop since it must simply widen the hole without
working in depth. To obtain a precise hole diameter, use the drill only
once until the stop stroke is achieved. Further uses may lead to a
poorer stabilization of the SinCrest device, in particular if little vertical
bone is available.
Ref 4357-RX pin Ø 4.0: confirms the correct angle and depth achieved
during osteotomy.
Ref 4334-SinCrest Ø 4.0 - black colour.
See the Ref 4333-SinCrest Ø 3.0
Ref 4340-SinCrest drill HB Ø 4.2: this drill must be used in case of hard
bone encountered during the screwing stage of the SinCrest Ø 4.0 de-
vice. This drill does not require positioning a stop since it must simply
widen the hole without working in depth. Prepare the site until the
desired depth is achieved. The osteotomy may be resumed by means
of the SinCrest Ø 4.0 device.
USAGE PROCEDURE
SINCREST MINI-KIT
Ref 4465 SinCrest Mini-Kit Ø 3.0.
Ref 4466 SinCrest Mini-Kit Ø 4.0.
To ensure correct centring, the use of the Ref 4337 SinCrest Drill Ø
3.0 with flat end and sharp tip must be preceded by a preparation by
means of an implant drill Ø 3.0mm until the predetermined depth of at
least 4mm, verifiable by means of a bulb-headed probe, is achieved
(see figure n. 12).
Proceed according to the surgical sequence starting from Ref
4337-SinCrest drill HB Ø 3.0

Stop positioning
8 stops are available for different depths (4-5-6-7-8- 9-10 and 11mm)
with laser marks for easier identification. The stops are organised
in sequence in the dedicated housings in the tray. Their positioning
on the Probe Drill Ø 1.2 and SinCrest drill Ø 3.0 takes place directly
by simply inserting the drill (see figure n. 13) mounted on the contra-
angle hand-piece, directly in the desired depth stop.
The stop already used may be temporarily positioned in the stop
housing, thus avoiding the direct contact with the operator's hands.
(see figure n. 14)
To avoid the accidental fall of the stops, slide the cover into the lock
position.
Washing and disinfecting
SinCrest Kit is not sterile when supplied. It must be disinfected,
washed and sterilised each time before it is used. Disinfect all the
SinCrest Kit devices by means of the dedicated germicide detergents
immediately after the surgical procedure to prevent cross contamina-
tion. Disassemble the Drill Gripper device to wash its internal parts
(see figure n. 15) and wash the inner cavity by with the help of a brush.
To disassemble the SinCrest device Ø 3.0 and Ø 4.0 use the Screw-
driver key in the Tray that unscrews the CONTAINER (see figure n.
16). Remove the PROBE component using the eject system on the
Screwdriver key as shown in figure n. 17 and the SPRING, then clean
the inner cavity with a brush.
To wash, use suitable detergents. Do not use hydrogen peroxide
(H2O2) nor chlorine-based detergents.
Wash the devices accurately with flowing water to remove the re-
sidual tissue with the help of a soft brush and check that they are not
damaged. Disinfect and wash the Tray each time immediately after
it has been used. Make sure that no residues remain in the drill and
tool housings; in certain cases, disassembling the tools is recom-
mended for better cleaning. When the Tray is washed in dedicated
tool-washers, place the tray diagonally for a better elimination of the
condensate steam.
Sterilization and storage
(see Device sterilisation and disinfection list)
Before proceeding with the sterilisation stage, correctly re-assemble
the components and make sure that the spring is repositioned as
shown in figure 16 (smaller diameter facing the internal part of the
device).
Make sure that the Drill Gripper device is not re-assembled during
the sterilisation, but only before using it. Use the dedicated SinCrest
Tray to arrange the surgical devices. Seal the tray or individual com-
ponents individually in a suitable sterilization bag.
Sterilisation should take place inside a steam steriliser at 121°C dur-
ing 30 min. always using validated sterilisation cycles according to
the laws in force. The maintenance of sterilisation is ensured by the
integrity of the bag: always check that it is not damaged before us-
ing it.
