Basal implants offer treatment options for cases that cannot be treated with conventional implants by utilizing basal bone areas that are free of infection and resorption. There are various types of basal implants including screw, disk, and plate forms that are inserted from the lateral aspect of the jaw. Basal implants have advantages over crestal implants like immediate loading, avoiding bone grafting, and extremely low failure rates due to their smooth surfaces limiting bacterial colonization. Prosthetic rehabilitation with basal implants aims to provide esthetics, hygiene, and prevent overload osteolysis through appropriate occlusal schemes.

REHABILITATION BY
BASAL IMPLANTS

2. Implantology starts where others gave up. Basal implants also offer a
unique opportunity for the implantologist to treat cases which cannot
be treated with the conventional implant systems.
Dr. Bhupendra Rizal

3. • “Basal Implant” is a term used in reference to the principles of utilizing
basal bone areas which is free of infection and resorption, and the
employing of the cortical bone areas. The load bearing tolerance of the
cortical bone is many times higher than that of the spongious bone

5. There are four basic types of basal implants available
II Disk Form.
IV Other Forms.
Both of the types can be further categorized into-
I. Screw Form
a. Compression Screw Design (KOS Implant)
b. Bi-Cortical Screw Design (BCS Implant)
c. Compression Screw + Bi-Cortical Screw Design (KOS Plus Implant)
Dr. Bhupendra Rizal

6. Triple disc BOI implants with or without beveling ,
larger disc at the bottom

7. Basal Disk Implant / Basal Osseointegrated Implant (BOI);
Bi-Cortical Screw (BCS) Implant
KOS Implant with Compression Screws; b. KOS+ Implant with
Compression and Bicortical Screws
Dr. Bhupendra Rizal

8. a) Basal Osseo-integrated Implant (BOI)
b) Trans-Osseous Implant (TOI)
c) Lateral Implant
3) Plate Form
a) BOI-BAC Implant
b) BOI-BAC2 Implant
4) Other Forms
a) TPG Implant (Tuberopterygoid)
b) ZSI Implant (Zygoma Screw)

10. BOI and BCS Implant Morphology
Disk of dimension of 9 mm × 12 mm or
10 mm × 14 mm with lengths 10–13.5
mm. The disk is usually 0.6 mm in height
The BCS has been developed up to 12
mm diameter and can be inserted
immediately into extraction socket.

Rizal

11. KOS and KOS Plus Implant Morphology
• These implants are designed like
compression screws, i.e.; these
implants when screwed into the
bone will compress the cancellous
bone surrounding the implant to
form more compact and dense bone

12. Advantages of basal implants
 Immediate loading
 Avoidance of bone grafting
 Single piece implantology
 Basal / Cortical bone support
 Minimally invasive (‘key hole’ implantology)
 Solutions for unfavourable bone situations
 Extremely low failure rates
 Virtually no incidence of Peri-implantitis…
Dr.
Bhupendra
Rizal

13. • BOI(Lateral basal implants):-
is inserted from the lateral aspect
of the jaw bone and it require
minimum bone height of 3 mm.
• Peri-implantitis incidence :Peri-implantitis
is the single most common cause for failure of
conventional implants. Judicious use of
monobloc, smooth surface basal implants
eliminate the threat of peri-implantitis by
almost 98%.
Dr.
Bhupendra
Rizal

14. Revolutionary designs and features of the basal implants help the implantologist in treating a wide
variety of cases which cannot be attempted with the conventional two / three – piece crestal implants.
Many of the implants have smooth surface designs which do not permit bacterial colonization on the
implant surfaces which in turn brings down the incidence of peri-implantitis considerably.
Dr.
Bhupendra
Rizal

15. Prosthetic Rehabilitation
• The aim of prosthetic rehabilitation is to provide esthetics, enable
hygiene practice and mainly to avoid overload osteolysis.
• Esthetics is taken care of by following the three FPs given by Dr. Carl
E. Misch. Overload osteolysis is prevented by providing appropriate
occlusal schemes which can be bilateral balanced, group function,
mutually protected and lingualized occlusion.
