situations and few missing teeth in either upper arch or lower arch. In such partial edentulous situations, implant prosthodontics has paved the way for contemporary dentistry, although conventional removable prosthodontics has been a treatment consideration where implant therapy is not possible due to local or systemic factors or economic reasons.2 While replacing missing teeth, our primary goal should be to restore function and preservation of oral tissues and esthetics. Numerous removable partial dentures (RPDs) are made where negligence to abovementioned factors occurs while attention is paid in mere replacement of missing teeth. This results in detrimental effect on remaining natural dentition.3 Prosthodontic rehabilitation of distal extension partially edentulous situations remains challenging. The support of distal extension RPD is derived from edentulous ridge and terminal abutment teeth. The terminal abutments act as fulcrum while functional movements of RPD as well as retentive clasps exert force on abutment teeth which may jeopardize the periodontium of these teeth.4 The advent and success of semi-precision and precision attachments in dentistry have improved the field of dentistry tremendously. Attachment retained RPD is the treatment therapy that can facilitate both functional and esthetic requirements of patients. The few retrospective studies available show a survival rate of 83.3% for 5 years, of 67.3% up to 15 years, and of 50% when extrapolated to 20 years.5,6 Staubli7 has classified attachments as: Class 1a: Solid, rigid, nonresilient Class 1b: Solid, rigid, lockable with U-pin Class 2: Vertical resilient Class 3: Hinge resilient Class 4: Vertical and hinge resilient Class 5: Rotational and vertical resilient Class 6: Universal, omniplanar. Selection of precision attachment should be based on physiologic, functional, and esthetic need of prosthesis. Primary indication of attachment retained partial denture is esthetics. When partial denture is essential for distal extension situations, the precision attachment is most equitable and definite means of distributing stresses. 1-3Senior Lecturer, 4Specialist Prosthodontist 1-3Department of Prosthodontics, Sudha Rustagi College of Dental Sciences and Research, Faridabad, Haryana, India 4Department of Prosthodontics, Dental Care Clinic, PHC, New Delhi Municipal Council, New Delhi, India
