KOS SINGLE PIECE DENTAL IMPLANTS…
SIMPLE, COST EFFECTIVE & PREDICTABLE
Dr. Prasanth Pillai MDS (OMFS), FICD
Single piece implants have been introduced recently in the field of Dental
Implantology. Though not applicable in all situations, single piece implants work well in D1 &
D2 bone and makes the entire gamut of procedures involved very practical, simple and
economical… not just for the implantologist, but for the patient too.
Recently I have introduced KOS implants (“King of Single Piece" – Swiss Implants introduced
by Dr. Ihde Dental, Germany & Switzerland) into my implant practice. I have seen that it has
brought about a dramatic and favorable change in my implant practice scenario. Therefore, I felt I
should share this information with all of you.

are more complex… very often screws
Maintenance is very simple… (when used) are to be tightened at periodic

conventional bridgework between the implant and the abutment.
However, it is to be kept in mind that KOS Single piece implants are not indicated in all cases &
they are to be used only in cases where there is good D1 / D2 bone.
KOS Implants are approved by the European Union and due to be approved by the US-FDA shortly.
Three other systems introduced by Dr. Ihde Dental are BCS, BOI & the Leone (Two Piece) Implant
systems. These along with KOS are able to provide excellent implant solutions in all types of
edentulous situations, avoiding complex surgical procedures.
KOS Implants: The Allfit® KOS® dental implant system is made of the highly fracture-
resistant Ti6Al4V ELI titanium alloy pursuant to ASTM F136. Single-piece implants
with apical compression thread and straight, flexible or angled solid abutment. Suitable
for crowns, bridges and bar connectors. The compression screw design facilitates
immediate prosthetic loading, provided the surgical placement was done correctly
(insertion of the restoration within three days or less). The salient features of KOS
implants are:* Perfectly manufactured precision implant with double-sandblasted
• * Highly fracture-resistant titanium alloy.
• * Single-piece implant with apical compression screw thread.
• * Straight solid abutment.
• * Facilitates immediate loading if the surgical placement was correct.
