Preprosthetic Surgeries and its Protocol for Complete Dentures: A Review.

In day-to-day dental practice many patients needing an ideal prosthodontic treatment plan are left dissatisfied due to unfavorable oral tissue conditions which cannot be improved without resorting to preconditioning of the oral tissues by means of surgical procedures. The Preprosthetic surgeries is performed to Prepare the soft and hard tissues of the upper and lower jaws to receive a comfortable prosthesis that will restore oral function, aesthetics, and facial form. Preprosthetic surgeries are group of soft and hard tissue procedures carried out in the oral cavity to create an architecture which is conducive for fabricating prostheses and improving their long-term prognosis. These procedures serve the needs of prosthodontists who plan replacements for missing teeth and associated tissues. A complete denture must restore function of the jaws (mastication of food, speech and swallowing) which can be achieved by creating proper supporting structures for subsequent replacement. Furthermore, prevent damage to adjacent structures by creating favorable tissue structures using surgical interventions like for example in a severely bony deficient mandible, it is essential to provide bone bulk for strength and protection for the neurovascular bundles in bony dehisced mandibular canals. In the maxilla, ideally an arched palatal vault has to be provided. [ABSTRACT FROM AUTHOR]
