Clinical evaluation of a new extraction method for intentional replantation

Abstract

Purpose: Intentional replantation (IR) is a suitable treatment option when nonsurgical retreatment and periradicular surgery are unfeasible. For successful IR, fracture-free safe extraction is crucial step. Recently, a new extraction method of atraumatic safe extraction (ASE) for IR has been introduced. Patients and Methods: Ninety-six patients with the following conditions who underwent IR at the Department of Conservative Dentistry, Seoul National University Bundang Hospital, in 2010 were enrolled in this study: failed nonsurgical retreatment and periradicular surgery not recommended because of anatomical limitations or when rejected by the patient. Preoperative orthodontic extrusive force was applied for 2-3 weeks to increase mobility and periodontal ligament volume. A Physics Forceps was used for extraction and the success rate of ASE was assessed. Results: Ninety-six premolars and molars were treated by IR. The complete success rate (no crown and root fracture) was 93% (n = 89); the limited success rates because of partial root tip fracture and partial osteotomy were 2% (n = 2) and 5% (n = 5), respectively. The clinical and overall success rates of ASE were 95% and 100%, respectively; no failure was observed. Conclusions: ASE can be regarded as a reproducible, predictable method of extraction for IR.

Clinical outcome of intentional replantation with preoperative orthodontic extrusion: a retrospective study

“…A few studies have been conducted on this approach to prevent root fracture and protect PDL during IR techniques (Kany , Choi et al . , Choi & Bae ). In this clinical study, no extraction failure was recorded, and no bone resorption and deep periodontal pocket were found after IR of those teeth extracted with partial osteotomy.…”

“…The teeth that received repeated nonsurgical root canal treatments and had multiple relatively large and physically weak roots, or little coronal crown structure to grasp because of substantial decay or existing core restorations were indicated for the preoperative orthodontic extrusion before the extraction procedure (Choi et al . ).…”

“…Recently, an improved atraumatic safe extraction (ASE) method for IR was suggested (Choi et al 2010). It recommended preoperative orthodontic extrusion for 2-3 weeks before surgery to increase tooth mobility and volume of PDL, which would allow easier extraction and reduce root resorption and ankylosis.…”

Cone-Beam Computed Tomography Study of Incidence of Distolingual Root and Distance from Distolingual Canal to Buccal Cortical Bone of Mandibular First Molars in a Korean Population

“…Recently, intentional replantation of mandibular first molar was reported by a new atraumatic, safe extraction method. In this method, preoperative orthodontic extrusion increases tooth mobility and extraction by using physics forceps to make easier extraction (22,23). If apicoectomy is unfeasible, intentional replantation could be the final treatment option to save the mandibular first molar.…”

Tooth replantation: an update

“…Lately, Choi et al suggested that using physics forceps could be considered as a reliable extraction instrument for a successful intentional replantation [14,15].…”
