A root submergence technique for pontic site development in fixed dental prostheses in the maxillary anterior esthetic zone

Abstract

PurposeThis case report discusses the effect of a root submergence technique on preserving the periodontal tissue at the pontic site of fixed dental prostheses in the maxillary anterior aesthetic zone.MethodsTeeth with less than ideal structural support for fixed retainer abutments were decoronated at the crestal bone level. After soft tissue closure, the final fixed dental prostheses were placed with the pontics over the submerged root area. Radiographic and clinical observations at the pontic sites were documented.ResultsThe submerged roots at the pontic sites preserved the surrounding periodontium without any periapical pathology. The gingival contour at the pontic site was maintained in harmony with those of the adjacent teeth, as well as the overall form of the arch.ConclusionsThe results of this clinical report indicate that a root submergence technique can be successfully applied in pontic site development with fixed dental prostheses, especially in the maxillary anterior esthetic zone.Graphical Abstract

Socket shield: A case report

“…This concept has been recently applied to teeth- or implant-supported fixed prostheses for pontic site development. [151617] On the basis of this background, a decision was made to leave the canine roots instead of performing a more invasive surgical procedure for extracting them. One of the main factors for the success of the SST is precisely that the root fragment does not come in contact with the external medium,[1] something that could facilitate the infection and also be an aesthetic problem.…”

Clinical Application of the Socket-Shield Concept in Multiple Anterior Teeth

“…Both vital tooth retention [ 21 , 22 ] and submergence of endodontically treated roots [ 23 , 24 ] have been recommended to prevent excessive resorption of the residual ridge. This concept has been recently applied to teeth- or implant-supported fixed prostheses for pontic site development [ 9 , 25 – 27 ]. Based on this background, a decision was made to leave the canine roots instead of performing a more invasive surgical procedure for extracting them.…”

Endodontic management of central incisor associated with large periapical lesion and fused supernumerary root: a conservative approach

“…[ 33 ] reported a 90% clinical success rate among 29 nonvital and 24 vital permanent incisor roots after more than 2 years of follow up, that were intentionally retained following a crown-root fracture. A submerged root underneath an old three-unit fixed dental prosthesis preserved the surrounding periodontium for 5 years without any periapical pathology [ 34 ]. Reames et al .…”
