Abstract

Prosthetic rehabilitation of a missing tooth with tilted abutments is yet an enigmatic and less unconventionally sought-after treatment strategy. Many methods have been previously reviewed over the years. This clinical report aims to integrate the principles of the segmented fixed dental prosthesis into a digital workflow. It elucidates the rehabilitation using a split-pontic design that mitigates the issue of developing a common path of insertion without much compromise to the tooth preparation to derive parallel prepared walls. This prosthetic design rather incorporates a common path of insertion into the pontic in the form of a key-keyway non-rigid connector design.

Highlights

Many methods have been previously reviewed over the years. This clinical report aims to integrate the principles of the segmented fixed dental prosthesis into a digital workflow. It elucidates the rehabilitation using a split-pontic design that mitigates the issue of developing a common path of insertion without much compromise to the tooth preparation to derive parallel prepared walls
A missing tooth complicates the oro-facial dynamics leading to various compensatory mechanisms that lead to enigmatic circumstances for prosthetic rehabilitation, especially when done after a prolonged delay [1]
One such issue is the drifting of the adjacent teeth to mitigate the prosthetic space. This leads to the abutment teeth tipping into an angular-assumed position for which accentuated tooth preparation is required to facilitate an aligned path for placing the fixed prosthesis with rigid connectors [2]

Summary

Introduction

A missing tooth complicates the oro-facial dynamics leading to various compensatory mechanisms that lead to enigmatic circumstances for prosthetic rehabilitation, especially when done after a prolonged delay [1]. One such issue is the drifting of the adjacent teeth to mitigate the prosthetic space. This leads to the abutment teeth tipping into an angular-assumed position for which accentuated tooth preparation is required to facilitate an aligned path for placing the fixed prosthesis with rigid connectors [2].
