Root submergence technique as a partial extraction therapy to preserve the alveolar ridge tissues: A systematic review and appraisal of the literature
The loss of alveolar ridge volume as a result of tooth
extraction has been noted in the literature since the 1960s.1-3
The full extent of why this happens is still not entirely understood,4 with a widely accepted explanation for the loss relating to factors that include trauma the extraction socket as a wound sees upregulation of inflammatory processes, resultant activation of osteoclastic activity, resorption of the extraction socket, and an eventual healing that
typically results in loss of tissue volume and architecture.5
Second, bundle boned removal of the tooth results in periodontal ligament (PDL) fibers being severed, loss of Sharpey fibers that insert into bundle bone, and a subsequent loss of the mineralized bone layer that lines the alveolus.4-6 At the buccal or facial aspect, the bone plate may consist entirely of bundle bone.
