Basis Implants: A Literature Review

It is a challenging procedure to rehabilitate an atrophied edentulous jaw by placing conventional

implants. Although various bone augmentation procedure like ridge augmentation, sinus lift are in

practice but it may lead to the morbidity of donor’s site. Sometimes patient is not willing for such

extensive surgical procedures. In such cases basal implants is a viable treatment option. Basal

implants derive support from the basal bone area which usually remains free from the infection and

less prone to resorption. This article discusses about the review literature of basal implants.

Key words: Basal Implants, Bone augmentation, Sinus lift, BOI Implants, BCS Implants

Introduction

Implant placement in severely atrophic jaws is

Furthermore, patients are

sometimes reluctant to undergo such extensive procedures. Basal implants were essentially developed

for use in atrophied jaw bones and are also called lateral implants or disk Implants. These implants

are not differentiated by the way they are placed and also by the way forces are disseminated.

“Basal Implant” is a term used in reference to the principles of utilizing basal bone areas which is free of infection and resorption[2], 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 [Figure1].

History

Basal implants were developed and improved in various stages, by the German and French dentists primarily. Single-piece implant was first developed and used by Dr. Jean-Marc Jullietin 1972[4]. His design was available in two sizes .Dr.Gerard scortecci, a French dentist in the mid 1980s presented an improved basal implant system complete with matching cutting tools. Two types of implants were developed by him, called “Diskimplants”, with internal and later external connectors attached to

Basal cortical bone has a much faster and stable repairing capacity.

Works well in compromised bone situations – Bone augmentation / grafting, sinus lifting and nerve trans-positioning procedures can be avoided. These implants particularly take advantage of the

bone available to avoid bone augmentation procedures. Whereas for conventional implants, the

available bone has to be modified by augmentation procedures to suit the implants.

Better distribution of masticatory forces – The basal implants are imbedded in high quality basal

bone. Hence, the masticatory forces get distributed to the cortical bone areas that are highly resistant

to resorption and have a very high repairing capacity.

Peri-implantitis incidence – Peri-implantitis is the common etiology behind failure of conventional

implants. This occours mostly due to the roughness of the implant surface along with the interface

problems between the multiple parts of the implant. The monobloc smooth surface basal implants
