Partial extraction therapies- A review

Abstract

The rehabilitation of missing anterior teeth is a big challenge to the prosthodontist. Ridge augmentation procedures are often needed to maintain a good emergence profile for a natural appearance. However the results of such procedures are often unpredictable in nature. Root submergence therapy has been implemented for many years and is found to be effective in preserving the alveolar bone-periodontal ligament complex, thus pre venting alveolar bone loss. The socket shield technique has been gaining popularity and is extensively practiced in the field of dental implantology. Modifications of this technique known as the proximal shield technique and pontic shield technique have been introduced in recent years and have provided promising results. These methods are used to maintain ridge contour by preserving tooth fragments to prevent bucco-palatal collapse of the alveolar ridge. This article is a review on these latest treatment modalities which are collectively known as The Partial Extraction Therapies.
