Effect of different splinting methods and fixation periods on root development of autotransplanted immature third molars

Effect of additional surgical procedures on root development of transplanted immature third molars

“…A normal pulpal condition of the transplant was concluded in the event of positive sensitivity testing or of pulp obliteration with no signs of inflammatory root resorption or periapical radiolucencies. A normal periodontal condition of the transplant was defined as normal transplant mobility, a physiological percussion sound, pocket probing depths up to 3 mm, and absence of ankylosis or inflammatory root resorption 8 . All root length measurements were performed by one examiner on intraoral radiographs taken in a standardized right-angle, long-cone technique with a film-focus distance of 30 cm.…”

“…Measurements were performed with sliding calipers graded in tenths of a millimeter (Dentaurum, Pforzheim, Germany) to the nearest 0.1 mm. The root length of the transplant was defined as the distance between the midpoints of two lines connecting both cementoenamel junctions and the two most apical and lateral points of the roots 8 . As only maxillary transplants with fused roots were used in the present investigation, the method applied was the same for maxillary and mandibular third molars.…”

“…A recent study found these additional surgical procedures had a negative effect on the pulpal and periodontal condition of transplanted immature third molars, and a possible correlation with revascularization disturbances of the pulp due to insufficiency of the recipient site was suspected 7 . Impaired revascularization of a transplant has also been reported to lead to a nutritional deficit of Hertwig's epithelial root sheath (HERS) 4,8,15 , therefore a negative effect of free bone autografts or splitting osteotomy of the alveolar process on postoperative root development of transplanted teeth might be assumed. The aim of the present study was to compare the results after transplantation into a fresh extraction site with those after use of free bone autografts or splitting osteotomy with regard to final root length and root length increment.…”

Tooth replantation: an update

“…A recent evidencebased appraisal of the literature indicates that splint type and duration were not generally a significant variable in relation to healing outcomes [24]. Although, ankylosis and replacement resorption may be observed with a long-term splinting, significant improvements outcomes with short-term spliting have not been shown [25][26][27]. Now it's recommended that the tooth be splinted for up to two weeks contrary to six weeks as before [24].…”

“…Yani travma geçiren dişin fizyolojik hareketlere izin vermesi gerekmektedir 30 . Rijit splintlemenin periodontal ligamentte aşırı bir sı-kışma meydana getirerek periodontal neoanjiyogeziste bozulmaya sebep olduğu, mekanik uyaran ile revaskü-larizasyona yardımcı olan orta-hafif derecede diş hareketine izin veren splintlerin ise, ankiloz oluşturmadığı ve kök gelişiminde canlı kalması gereken hertwing epitel kınını koruduğu bildirilmiştir 41,42 . Fizyolojik hareketler periodontal ligamentteki kan akımını ve venöz dönüşü sağlayarak revaskülarizasyonu teşvik eder 43 .…”
