“…Patients should be advised to consume soft foods within 4 weeks after the operation. Furthermore, the application of a mini titanium plate can effectively prevent the occurrence of mandibular fracture ( 23 ) and avoid serious complications (fractures) in patients with high fracture risk.…”

Background A quantification of the residual bone mass of the mandible (B/A) was utilized in this study to examine the correlation between mandibular fracture and residual bone mass. To improve the clinical utilization rate and reduce the incidence of iatrogenic mandibular fractures, the B/A ratio calculation should be simplified. Material and Methods Data were collected from the Yanbian University Hospital on 175 cases of mandibular fracture with third molar (M3), 67 normal cases without fractures and 20 cases of impacted teeth extraction. Twenty cases of iatrogenic mandibular fracture were collected, and the case records and panoramic radiographs of the patients were recorded. Results The average B/A ratio of mandibular angle fracture group was 0.61±0.10.The value of B/A was found to be statistically significant in terms of whether M3 emerged from alveolar bone ( P = 0.001), location (horizontal P < 0.001, vertical P < 0.001), the degree of impaction ( P < 0.001), the number of roots ( P < 0.001), the difference in impaction ( P < 0.001), and the fracture type ( P = 0.002). The average B/A ratio of normal group was 0.62±0.10. In the statistical results of the B/A value of normal patients, M3 involving alveolar bone ( P < 0.001), position classification ( P < 0.05), degree of impaction ( P < 0.001) and presence or absence of a root ( P < 0.05) were statistically significant. The average B/A ratio of iatrogenic mandibular angle fracture group was 0.28±0.08. The average B/A ratio of the extraction group for impacted teeth was 0.62 ± 0.09. Conclusions There is a high risk of mandibular angle fracture when the (B/A) value of the residual bone height (B) in the mandibular M3 area compared to the mandibular bone height (A) in the M3 area is less than 0.4. Key words: Residual bone height (B/A), mandibular angle fracture, tooth extraction risk, panoramic radiographs, third molar, orthopedics.

“…Most late lower jaw fractures occur while chewing more consistent foods, such as bread, nuts and meats, when the masticatory forces required to grind food can cause severe trauma to the already weakened bone by surgery. Most cases report that at the moment of late mandible fracture, the patient hears a "crack" on the affected side during chewing, accompanied by pain, a rapid evolution to edema and trismus, with or without malocclusion and paresthesia (3) (1) (12).…”

Extraction of lower third molars is one of the most common procedures performed in oral surgery, may undergo intraoperative and post complications, with an incidence that ranges from 3.47% to 9.1%, including: bleeding, pain, dental or bone fractures, displacement of teeth or fragments, subcutaneous emphysema, nerve damage, edema and infection. Treatment depends on the fracture characteristics, maxillomandibular fixation and surgical treatment by means of fracture reduction and fixation. This article was carried out based on a search in online databases, such as PUBMED, written in Portuguese and English. Late mandibular fracture after extracion of third molars occurs between the 2nd and 6th week after surgery, most of which occur during chewing more consistent foods can cause severe trauma to the bone weakened by surgery. For this reason, the need to inform operated patients about postoperative care and the limitation of masticatory strength for 2 months after surgery, so that there is an adequate bone repair in the operated region. we conclude the importance of guiding patients on the risks inherent in the surgery to which the patient will be submitted, as well as guiding the postoperative care, necessary both in writing and verbally, to avoid any post-surgical complications or legal implications that may occur.

“…Several clinical methods have been proposed to upright tilted second or third molars; these can be divided into two categories: (1) pushing the tilted molars backwards by a spring soldered to bands on the first or second molars [6] or a tipback cantilever [7] and (2) pulling the tilted molars backwards from the distal side by TADs (Temporary anchorage devices) inserted into the retromolar region [8].…”

Protracting lower second molars and uprighting horizontally impacted third molars is a significant orthodontic challenge in patients who require the extraction of severely decayed first molars. Here, we describe the use of biomechanics to upright 90 • -tilted lower third molars following second molar protraction. Herein, we introduce a technique for uprighting the lower third molars by (1) the placement of superelastic nickel titanium archwires, (2) bonding, and (3) repositioning of a buccal tube in a tilted position to compensate for the efficiency of Ni-Ti (nickel-titanium) wire. The treatment mechanics used for our two cases showed that even severely impacted third molars can be uprighted by routine continuous straight-wire techniques. This technique proved to be a simple, efficient and reliable treatment option for uprighting horizontally impacted third molars.
