Autotransplantation of the Lower Posterior Teeth: A Comprehensive Review

Abstract

A new era in modern dentistry has emerged where tooth loss is no longer an issue as a result of rapid advancements in implantation and alveolar ridge reconstruction. Despite its wide range of indications, autotransplantation is dependent upon careful patient selection and a suitable technique to ensure successful results both functionally and aesthetically. It is possible to restore physiological occlusion, aesthetics, and masticatory function by varying implant length, diameter, surface, and design, along with autogenous, alogenous, alloplastic, or xenogenous bone substitutes. However, none of the technologies that are used in implant dentistry today can adapt to a child's growing jaw during adolescence. Thus, the young age of the patient restricts implants and creates a challenge for dentists wishing to replace missing teeth. Therefore, tooth autotransplantation can be a good option for treatment. Our objective in this review is to highlight the biological principles required for the successful autotransplantation of teeth. Limits, indications, and prognoses will be analyzed. Hopefully, with increased awareness and acceptance in the dental profession, autotransplantation will become another viable treatment option for those with compromised teeth who still have significant growth potential.

Autotrasplante dental como nuevo enfoque para rehabilitar espacios edéntulos

“…Sr. Editor, La caries, enfermedad periodontal, fracturas dentarias, iatrogenias y procesos endodónticos fallidos siguen siendo las causas más comunes que conducen a la pérdida de uno o varios dientes, generando espacios o brechas edéntulas que alteran la oclusión y el sistema estomatognático (1). Existen diversos tratamientos que permiten reemplazar las piezas perdidas devolviendo la funcionalidad y estética, entre ellos las prótesis dentales e implantes.…”

Unusual Indications of Teeth Transplantation: A Literature Review

“…The bulk of published literature on dental transplantation describes autogenous transplantation of teeth within various conditions and indications as a reliable treatment option [1][2][3][4][5][6][7][12][13][14][15][16][17][18][19][20][21]. Allogenic dental transplantation cases, where donor and recipient are two different individuals, are scarce in the medical literature due to several reasons.…”

“…Many publications stated that the recipient site must be free from any pathological activity in order to achieve successful transplantation [ 13 , 14 ]. At any rate, pioneering works exist that indicate the possibility of immediate dental transplantation into lesion-associated recipient sites after being managed appropriately [ 12 , 15 , 16 ].…”

“…Sometimes, patients refuse orthodontic approach as it entails significantly increased treatment time and costs caused by the presence of canine impaction [ 30 ]. In such scenarios, canine transplantation can offer a worthy option to restore its natural orientation in a faster, more expedient way [ 14 , 31 ]. Zufía et al reported an autotransplantation case of impacted maxillary canine combined with guided tissue regeneration, guided bone regeneration, and orthodontic treatment [ 32 ].…”

“…Many publications in the literature concerning transplantation of teeth assume that patient selection must ensure good general health with no medical issues, otherwise dental autotransplantation will be contraindicated [ 14 , 51 , 52 ]. Autotransplantation of teeth should be avoided in uncontrolled systemic conditions and endocrine disorders that may contribute to possible root resorption, e.g., hyperparathyroidism, calcinosis, Gaucher's disease, and Paget's disease [ 53 ].…”
