Sinus augmentation using an dystopic autogenous tooth
This video showed a new, economical, easy-to-harvest and completely autogenous graft material for sinus floor elevation: crushed tooth material.
The speaker showed a case involving lateral sinus elevation, where the left upper first molar was absent, the second molar was present and the third molar was included. The third molar was extracted and cut with burs. The tooth slices were then placed into a manual bone mill. The milled tooth material was then mixed with water and bone particles which had previously been collected using a bone scraper.
The procedure was as follows:
- lateral osteotomy
- the graft material was compacted
- implants were placed and the flap was sutured
- a submerged healing period of four months was observed
Two control CBCT scans were taken, one immediately after surgery and another one 12 months later. The CBCTs recorded a bone volume gain of 1.63 and 1.46 cm3 respectively.
“The clinical success rate of this procedure in 55 patients and after a seven-year follow-up period was 100%”
It is well known that dentin material and bone have a similar composition: hydroxylapatite, type I collagen and H2O. The six-month histological evaluation showed that bone formation (osteogenesis) had taken place, with enamel and dentin particles encapsulated in both sinus and alveolar ridge augmentations (Pohl et al. 2016; Pohl et al. 2017). The speaker reported that the clinical success rate of this procedure in 55 patients and after a seven-year follow-up period was 100%.
