Unique, Cost-effective and Retentive Removable Prosthesis to Rehabilitate Long Span Kennedy's Class I Edentulism with Custom Attachment System: A Case Report.

Aim: This case report describes about a distinctive custom-made attachment on the abutment teeth to improve the retention and stability of the removable partial denture (RPD). It also throws light on the cost-effective method for altering the abutment teeth with the aid of the crowns and custom-made attachments.

Background: Achieving retention in Kennedy's class I bilateral edentulism usually affects the abutment teeth's periodontal health and eventually the retention is compromised. Distal extension edentulism also affects patient's masticatory efficiency. The rehabilitation of a patient with the long span Kennedy's class I condition complicates the problem because of the unavailability of enough abutments to support the prosthesis. Conventional removable prosthesis with clasps and cantilever fixed partial prosthesis are not advisable in this situation for the same reason.

Case Description: A case with Kennedy's class I modification 1 partially edentulous arch with 1st and 2nd molars missing along with central incisors was rehabilitated with an inexpensive custom attachment using die pin and sleeve for giving a fixed prosthesis on abutment teeth and removable prosthesis with missing teeth.

Conclusion: This technique has advantages of retention better than conventional RPDs, protection of abutment health by restoring it with crown, easy to place and remove and very cost-effective.

Clinical Significance: The entire technique demands less skill compared to semi precision and precision attachments.
