Abstract

The hand is a powerful tool and its loss causes a severe psychological and physical drawback. A considerable number of people each year suffer finger or partial finger amputations as a result of malignant disease, trauma, and congenital deformity.

Prosthetic restoration is usually considered difficult for the whole or a part of the finger and it worsens if multiple fingers are involved. Additionally in patients with mixed connective tissue disorders with overlapping clinical features of scleroderma and arthritis any undue pressure from the artificial rings or vacuum fit of the prosthesis might cause further vasoconstriction that could worsen blood flow to extremities. This clinical report describes a simple and economical method for prosthetic rehabilitation of a patient with mixed connective tissue disease following digital loss using a custom made prosthesis with medical grade tissue adhesive as retentive aid.

Abstract

Aim: The aim of this study is to compare and evaluate the effects of auxillary grooves on retention of complete cast crown on molars. Method: Thirty mounted teeth were divided randomly into three groups of 10 each and grooves are placed using NOF104R diamond point. In group A, no groove is placed – control, group B, one groove is placed proximally in the centre of mesial surface – Test group. In group C, two groove is placed proximally, each in centre of mesial surface and distal surface - Test group. Castings were prepared luted and retention was checked using a Universal Testing machine Results were subjected to one way ANOVA and Student T Test. Results: Auxilary retentive features produces a significant increase in retention of complete cast crowns. Incorporation of two proximal grooves on the mesial and distal side produces the most retention as compared to one groove or conventional tooth preparation. Conclusion: Retentive features produces a significant increase in retention of complete cast crowns.
