ABSTRACT:
Precision attachment partial dentures have been used
successfully on natural tooth abutments since 1920. There is
significant number of patients who could benefit from this
treatment option, both short and long term. However, lack of

provide an overview and a simplified approach to this treatment
modality by a clinical case report.

INTRODUCTION
Esthetically and functionally successful prosthetic rehabilitation requires careful attention and meticulous
treatment planning. Precision attachments offer considerable advantages in dentistry because of their
flexibility. The use of precision attachments adds a new dimension to dental treatment and also broadens
the referral base of a dental surgeon.1 Successful restoration of the dentition requires plenty of contemporary
and conventional treatment techniques and planning and attachment retained partial dentures are one such
kind of treatment modality in prosthodontics.2 Precision attachments could be extracoronal and intracoronal.
Intracoronal describes an attachment within the confines of the cusps and normal proximal axial contour or
within the normal contours of the crown of a tooth.3 Extracoronal is that attachment which exists outside, or
external to, the crown portion of a natural tooth. The extracoronal attachment projects outside the crown
and provides either a rigid or resilient connection between the teeth and the prosthesis. Attachment-retained
cast partial dentures facilitate both esthetic and functional replacement of missing teeth. Studies have shown
a survival rate of 83.35% for 5 years, of 67.3% up to 15 years, and of 50% when extrapolated to 20 years.4 This
paper describes a case report of a patient with maxillary and mandibular bilateral distal extension Kennedys

DISSCUSSION:
Dr. Herman Chayes first reported the invention
of attachment in early 20th century. To the late 20th
century, with growing technology the attachment
has been applied to the superstructure of implant5.
Precision attachment has exceptional feature of
being a removable prosthesis with improved
aesthetics, less post-operative adjustments and
better patient comfort and psychology are drastically
improved. 6 They are mostly indicated in long
edentulous spans, distal extension bases and non
parallel abutments.
Stress control on the abutment is an essential
factor for the success of distal extension cast partial
denture which is achieved through dual impression
technique, broad coverage , stable denture base ,
rigid design , physiologic shimming, splinting of
abutments, proper selection of attachments.7-8
The recommended procedure has several
advantages over the conventional prosthesis. In this
case report abutments were of adequate clinical
crown height to receive attachment; multiple
abutments were splinted anterior to edentulous span
to aid in better distribution of stresses. As the cast
partial denture is a fixed removable type,
maintenance of the oral hygiene is relatively easy.
Added to this the laboratory procedures are simple
due to the available preformed prosthetic
components and the treatment is economical. By the
end of the treatment patient comfort and psychology
had drastically improved and started participating
in social activities.

Conclusion:
A comprehensive evaluation, multi-disciplinary
approach and a sequential treatment plan, worked
out in harmony with the patients aesthetic demand
, perceptions, and periodic recall preventative
therapy is important for a long-term successful
outcome of fixed removable precision attachment
retained removable partial denture.
