Oral Imaging - interpretation of the image 4: End

Study notes, thank the author.

Go to Shanghai to participate in the Chinese Stomatological Association 2018 Annual Meeting delayed a few days, today finished it together.
Implant evaluation

points: ① successful osseointegration - bone / implant surface without fibrous tissue ingrowth, direct contact between the bone and the metal implant surface; tip implant bone loss minimum ②; ③ peri-implant without a case; ④ the base station in conjunction with suitable fixing means.

A 2 years after planting, osseointegration success, note that no transmission between shadow and bone explants.
B immediately after planting buccal and lingual display position of an implant, and the implantation angle explants.

A. 24 explants around vertical bone loss, while 23 did not.
B. osseointegration failure. Note the surrounding body image transmission plant.
C. Display is not properly fixed to the base, there is a transmission image around the base, apical region has before transmission image.
Assess the site before planting inappropriate academic and clinical radiation may cause implantation failure and even more serious, leading to temporary or permanent nerve damage, and produce medical litigation.
Imaging assessment of impacted teeth.
Lower third molar, considerations
angle

crown: size, shape, and whether there is caries decay range, whether there is resorption (resorption) and its severity.
Root: number, shape, bent condition, the degree of development.

Pulling the left is a good root is consistent with a single pull direction or the bending direction. It is difficult to pull the right side of the bending direction opposite to the extraction direction root or root end enlargement.
Relationship with the mandibular canal apical: x-root sheet and the mandibular canal is usually due to close both the image caused by overlapping. Sometimes, however, there is indeed a close relationship between the two. Root canal in contact with the lower jaw is possible, in rare cases, the developing root are contained within the mandibular canal.

Imaging explain the relationship between the root and the mandibular canal

or CBCT beat it.
Imaging diagnosis of dental trauma.
Dental trauma type: dental defects, dislocation of the tooth, alveolar bone injuries, other injuries.
Dental defects comprising: a crown portion only (involving only the enamel, dentin, and enamel involved, enamel dentin and pulp involved, involving the enamel dentin and cementum, dentin involving enamel and cementum pulp), root off (with / without crown defect).
Dislocation teeth into: shock teeth (Concussion), subluxation, dislocation embedded teeth, the teeth projecting type dislocation (Extrusive luxation), lateral dislocation (Lateral luxation), full dislocation (Avulsion).
Alveolar damage includes: damage to the tooth socket, alveolar damage, related jaw fracture.
Imaging Explanation: between transmissive image ends; root shape change, the periodontal ligament space interrupts.



Three-dimensional image onto a two-dimensional, there are still limitations, they still can shoot CT CT to shoot it.

Temporomandibular joint imaging
temporomandibular joint positions in different states

A. initial closed position the opening position B. C. D. large opening position opening position.
Usually beat joint sheet (Hsueh bit slice), if necessary shot CBCT: ① the complete evaluation of the entire condition of joints, to determine any abnormality of bone diseases or the presence and location; ② when the patient was observed condyle and fossa when trismus status; ③ evaluation condyle, and the joint socket joint capsule damage.
Temporomandibular joint disorder syndrome imaging performance: ① condyle articular surface of the head and normal morphology; ② socket normal morphology; ③ increase or decrease the joint space. Wherein the gap increases only suggestive of infection; ④ when engaged condition after the shift or the joint head may be shifted before the glenoid fossa; ⑤ condyle reduced mobility. (UK 2011 guidelines in cases of imaging studies to prompt only soft tissue damage and no hard tissue damage and can not provide any information)

The next thing going to summarize the annual meeting, from the resin filling start. First established a Flag, we will share with you.
