Current state of dental autotransplantation
2010
The aim of this study is to analyse the current situation in dental autotransplantations within the different therapeutic alternatives that the dentist has available to replace a tooth in the dental arcade. For some authors this is an option headed for failure, whereas for others, it is an alternative to keep in mind. In this study we analyse the factors related to the predictability of the technique, based on an analysis of research work published in the scientific literature up to date. We also present two clinical cases performed by our team and their subsequent evaluation. In spite of the satisfactory results seen when reviewing the existing literature, we cannot say that dental autotra…
Autogenous tooth transplantation : evaluation of pulp tissue regeneration
2010
Objective: The aim of this study was to assess the pulp survival that occur in transplants of autologous teeth, by comparing two surgical techniques: the conventional technique (autotransplantation for newly formed alveoli), and an alternative technique, (autotransplants for alveoli in the initial phase of healing). In each surgical techniques were applied, randomly, either saline solution or Emdogain ®. Study Design:The study group comprised 26 patents, in which 28 teeth were transplanted to recipient sockets prepared mechanically. Of the 28 teeth transplanted, 4 were intentional replants, and of the remainer, 11 had the apex closed and 13 open. The mean age at the time of transplantation …
Parathyroid Autotransplantation During Thyroid Surgery: A Novel Technique Using a Cell Culture Nutrient Solution
2016
Introduction: Parathyroid autotransplantation is an easy procedure with a low complication rate. We adopted the transplantation into the sternocleidomastoid muscle, which allows an easier and time-saving surgical procedure using the same surgical incision. Methods: In this study, we retrospectively reviewed the records of 396 consecutive patients, who underwent total thyroidectomy for benign thyroid disease. In all cases in which a parathyroid was damaged or inadvertently removed, the gland was transplanted; before the autotransplantation, the parathyroid tissue was put in a cell culture nutrient solution for 5 min, afterward fragmented, and then was transplanted in the sternocleidomastoid …
Children born after autotransplantation of cryopreserved ovarian tissue. a review of 13 live births.
2011
Abstract Introduction. Premature ovarian failure (POF) can occur naturally at an early age or be due to iatrogenic agents. Indeed, ovaries are very sensitive to cytotoxic treatment, especially to radiation and alkylating agents. Methods. Several options are currently available to preserve fertility in cancer patients and allow them to conceive when they have overcome their disease: embryo cryopreservation, oocyte cryopreservation, and ovarian tissue cryopreservation. Cryopreservation of ovarian tissue is the only option available for pre-pubertal girls and women who cannot delay the start of chemotherapy. Findings. Since the first live birth after autotransplantation of cryopreserved ovaria…
Fresh Human Orthotopic Ovarian Cortex Transplantation: Long-term Results
2006
An increasing number of young women are being diagnosed with cancer, and most cancer treatments have irreversibly negative effects on reproduction. Ovarian stimulation and preservation of oocytes or embryos is far from an ideal solution, in part because hormonal treatment may adversely affect some cancers. Another possibility is cryopreservation of ovarian tissue for later autotransplantation, but the ischemic damage caused by the procedure can lead to follicle loss. Using the ovarian medulla for orthotopic ovarian cortex transplantation might limit the risk of ischemia because the ovarian artery would assure a good blood supply. In addition, the medulla may have a role in follicular develo…
Third molar autotransplant planning with a tooth replica. A year of follow-up case report
2021
The advantages of dental autotransplantation and its high level of clinical success mean that it should be considered as a therapeutic option when replacing a lost tooth. In order to achieve optimum results, it is necessary to know the technique of dental autotransplantation, promoting its use whenever the clinical conditions to perform it are present. The objective of this article is to describe the technique in detail by means of a clinical case of a dental autotransplant whose donor tooth was a third unerupted molar. A 39-year-old male patient with no medical history of interest. On clinical examination, tooth 2.6 shows vertical fracture with indication of exodontia. A compatibility stud…
Prospective Study of Parathyroid Graft Function in Patients with Renal Hyperparathyroidism After Total Parathyroidectomy and Heterotopic Autotranspla…

Evaluation of the value of gradients for intact parathyroid hormone after total parathyroidectomy and heterotopic autotransplantation for renal hyperparathyroidism.Prospective long-term follow-up study.Teaching hospital, Germany.A total of 115 patients operated on for renal hyperparathyroidism between 1 August 1987 to 15 August 1997.100/115 had total parathyroidectomy with autotransplantation.Analyses of serum calcium, alkaline phosphatase, and intact parathormone in serum 1, 4, 8, 12, 18 and 24 months postoperatively and annually thereafter. Parathormone gradients were calculated as the ratio of the parathormone concentrations in the antecubital venous blood of the grafted and the non-graf…
Prospective evaluation of parathyroid graft function after total parathyroidectomy and heterotopic autotransplantation in renal hyperparathyroidism b…
1998
The value of gradients for intact parathyroid hormone (PTH) in the assessment of graft function after total parathyroidectomy/autotransplantation for renal hyperparathyroidism was evaluated in a prospective follow-up study. Altogether 99 patients who underwent operation from August 1, 1987 to December 31, 1996 were prospectively investigated and reexamined postoperatively, including analyses of serum calcium, alkaline phosphatase, and intact PTH in the antecubital venous blood of both arms. The postoperative course is known for all patients. Of the 99 patients included in the study, 95 underwent one to nine reexaminations (median three) over follow-up periods of 1 month to 5 years (median 2…
Operative Therapie des primären Hyperparathyroidismus im Neugeborenenalter
1988
This is a report on a neonatal primary hyperparathyroidism (NPHPT) treated by total parathyroidectomy and autotransplantation of parathyroid tissue into the forearm musculature. Histologically, the glands were composed of a "chief cell hyperplasia" of the parathyroid tissue. Clinical manifestation in neonates and differential diagnosis of HPT are discussed. Indication for operation and surgical procedure are described.
