Objective : The aim of this study was to evaluate the clinical outcome of autotransplantation of mature third molars to fresh molar extraction sockets using 3D replicas.
Materials and Methods : Ten patients underwent teeth autotransplantation. We observed the mobility, percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth duringtwo yearsfollowing up, which were transplanted into fresh molar sockets by using 3D replicas, and GBR when it is necessary.
Results : The average extra-oral time of donor tooth had been shortened to 1.65 min when used the 3D replica. Some probing depth of the transplanted tooth were deeper than 3 mm at 4 or 5 weeks temporarily. And one patient felt slight sensitive when chewing with soft food at 4 weeks, then disappeared. The clinical examination of the autotransplantation teeth during one year follow-up showed no sign of failure.
Conclusions : The tooth autotransplantationusing 3D replica is an effective method which can reduce the extra-oral time of the donor teeth and may result in less failure.
Clinical Relevance : The new 3D replica of donor tooth can make the surgery of tooth autotransplantation much easier, and improve it success rate.
Background: The aim of this study was to evaluate the clinical outcome of autotransplantation of mature third molars to fresh molar extraction sockets using 3D replicas. Methods: Ten patients underwent teeth autotransplantation with or without GBR. We observed the mobility, percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth during two years following up, which were transplanted into fresh molar sockets by using 3D replicas, and GBR when it is necessary. Results: The average extra-oral time of donor tooth had been shortened to 1.65 min when used the 3D replica. Some probing depth of the transplanted tooth were deeper than 3 mm at 4 or 5 weeks temporarily. And one patient felt slight sensitive when chewing with soft food at 4 weeks, then disappeared. The clinical examination of the autotransplantation teeth during one year follow-up showed no sign of failure. Conclusions: The tooth autotransplantation using 3D replica with or without GBR is an effective method which can reduce the extra-oral time of the donor teeth and may result in less failure.
Objective: A large maxillary odontogenic cyst could intrude into the maxillary sinus. The traditional approach following surgery for such a cyst is the Caldwell-Luc procedure However the traditional CDL procedure is associated with more complications and damage of the sinus mucosa. The purpose of this study was to assess a new method with easier operation, which not only prevented postoperative infection but also caused less damage to the maxillary sinus mucosa.Methods: A large odontogenic cyst in the maxillary sinus of 40 patients was diagnosed through radiographic imaging and postoperative histopathology. Twenty patients were treated with maxillary sinus saline irrigation after cyst resection surgery, while 20 patients underwent the traditional Caldwell-Luc procedure. The therapeutic efficacy was evaluated by clinical examination and radiographic imaging; the longest follow-up was 36 months.Results: The postoperative recovery of the 20 patients treated with sinus irrigation. Six patients had mild swelling (30%), 12 had moderate swelling (60%), and 2 had severe swelling (10%); 16 had mild pain (80%), 4 had moderate pain (20%), and 0 had severe pain (0%). Among the 20 patients treated by the Caldwell-Luc approach. Immediately postoperatively, 2 patients had mild swelling (10%), 12 had moderate swelling (60%), and 6 had severe swelling (30%); 10 had mild pain (50%); 6 had moderate pain (30%), and 4 had severe pain (20%). On the second day after surgery, a mild temperature elevation (38.0°C-39.0°C) was noted in 8 patients (40%) treated with the Caldwell-Luc procedure and 1 patient (5%) treated with saline irrigation.Conclusion: Sinus irrigation following large odontogenic cyst surgery involving the maxillary sinus can serve as an alternative to standard CDL and has the advantages of fewer complications, reduced trauma, restoration of the mucosa and more satisfactory results.
Objective
The aim of this study was to evaluate the performance of autotransplantation of a mature third molar to a fresh molar extraction socket using a 3D replica.
Materials and Methods
Ten patients underwent autotransplantation of teeth. We observed the mobility, percussion, radiography examination, the probing depth and the masticatory function of the transplanted teeth during one year following up, which were transplanted into fresh molar sockets by using a 3D replica, and GBR when it is necessary.
Results
The average extra-oral time of donor tooth had been shortened to 1.65 min. The clinical examination of the autotransplantation teeth during one year follow-up showed no sign of failure. Expect one patient feel slight sensitive when chewing with soft food at 4 weeks, and 3 points of probing depth deeper at different patients than 3mm and 1 points of probing depth deeper than 4mm at 4 weeks among them, and 1 points of probing depth deeper than 3mm at 5 weeks at the same patient.
Conclusions
The autotransplantation of teeth using 3D replica is an effective method which can reduce the extra-oral time of the donor teeth and the demand for the experience of a surgeon, and had a high success rate.
Clinical Relevance
The new 3D replica of donor tooth can make the surgery of tooth autotransplantation much easier, and improve it success rate.
