The study also aimed to evaluate the wound healing, duration of the procedure, and level of gingival laceration associated with the use of these two instruments. The study was a randomized controlled clinical trial involving 26 patients requiring nonsurgical tooth extractions bilaterally. The subjects were randomized into two groups: the study group, where flexible periotomes were used to break the periodontal ligament, and the control group, where conventional periotomes were used. A total of 52 extractions were performed, either for orthodontic or implant placement purposes. After the extractions, the researchers evaluated the level of gingival laceration, duration of the procedure, and wound healing on postoperative days 1 and 7. Any complications that arose were also noted. The study group (flexible periotome) and control group (conventional periotome) were compared, and the results showed that the flexible periotomes required a shorter duration of time (around 4 minutes) compared to conventional periotomes (7 minutes). Additionally, gingival lacerations were found to be less severe in the study group. In conclusion, the use of flexible periotomes was found to be more efficient in atraumatic dental extractions compared to conventional periotomes. This study highlights the importance of using newer technology to perform atraumatic extractions, particularly in the era of implantology where there is an increased demand for such procedures.展开更多

In order to prevent this reduction or at least recompense the loss of bone dimensions, the alveolar ridge preservation (ARP) technique was developed. Objectives: This research studied the vertical and horizontal bone dimensional changes as a result of non-molar teeth extraction alone against extraction with alveolar ridge preservation utilizing composite (bioceramics/collagen) graft by cone-beam computed tomography radiographies analyses. Material and Methods: This research was a randomized split-mouth controlled trial. 12 patients need extraction of the maxillary non-molar teeth were enrolled and allocated into 2 groups. 12 sockets after atraumatic extraction were filled with a composite graft in the role of the test group, 12 sockets left to unassisted healing after atraumatic extraction without any graft materials in the role of the control group. Two CBCT radiographs were taken at baseline and at 4 months after extraction for comparison. Both vertical and horizontal resorptions of the alveolar ridge were analyzed between test and control group by CBCT radiographs. Results: 4 months after extraction, there was a mean of vertical alveolar bone resorption compared with the baseline (0.56 ± 0.15 mm) in the test group and (1.47 ± 0.30 mm) in the control group. Whereas it was a mean of horizontal alveolar bone resorption compared with the baseline (0.90 ± 0.16 mm) in the test group and (2.26 ± 0.30 mm) in the control group. Therefore, there was a significant difference between the two groups. Conclusions: Within the limitations of this research, we demonstrated that the osteogen-plug technique significantly decreased the reduction of the bone dimensional in comparison to the tooth extraction alone, and showed that the dimensional change of the alveolar ridge after tooth extraction was minimized by using an osteogen-plug.展开更多
