- Stomatognathic functional improvement in a patient with a canted occlusal plane and temporomandibular disorder treated with an edgewise appliance and miniscrewsby Kenji Hoshi, Toru Deguchi, Maki Goto, Toko Chida, Nobuo Takeshita, Ichiro Takahashi, Teruko Takano-Yamamoto on 22/10/2021 at 12:00 am
Generally, a canted occlusal plane results in esthetic problems, such as an asymmetric mandible with midline deviation, and functional problems, such as temporomandibular disorder (TMD). For many years, orthognathic surgery has been used to level a canted occlusal plane. However, similar effects might be achieved by intruding the posterior teeth using a miniscrew. This case report describes a patient with a canted occlusal plane, mandibular deviation, shifted dental midlines, and TMD treated with an edgewise appliance using miniscrews as anchorage.

- Risky businessby Laurance Jerrold on 01/10/2021 at 12:00 am
You are being sued for malpractice. The plaintiff said your treatment was negligent and caused significant injury. There is no claim for lack of informed consent. At trial, your defense attorney wants to present evidence that informed consent was given for the procedure and the known risks of the procedure. Obviously, the plaintiff objects and wants the court to preclude the admission of any such evidence because informed consent is not on the menu, only the claim for negligence. Can the information be entered into evidence and considered by the jury? Such is the making of Mitchell v Shikora, No.
- Missing participant outcome data in meta-analysis. Part 2by Loukia M. Spineli, Nikolaos Pandis on 01/10/2021 at 12:00 am
Modeling missing participant outcome data (MOD) in a meta-analysis has been advocated as conceptually and statistically advantageous to methods that manipulate the data before analysis by imputing or excluding MOD.1 In this column, we introduce the pattern-mixture model for an aggregate binary outcome. We also provide recommendations to handle MOD in meta-analysis properly.

- Pricelessby Peter M. Greco on 01/10/2021 at 12:00 am
A dentist who is among your strongest advocates referred Cindy to you to upright her mandibular right second molar before implant replacement of the adjacent first molar. Try as you might, you are having difficulty controlling the extrusion of the tooth as it moves. The second molar is restored with a crown, so you explain to Cindy that you’ll reduce the crown to prevent traumatic occlusion and facilitate movement. You realize you’ve perforated the crown soon after you start your handpiece. Fortunately, the tooth had been endodontically treated, so Cindy has no idea of what happened.
- Concern about possible inferior alveolar nerve compression after molar intrusionby Kai Xia, Liyuan Yu, Jun Liu on 01/10/2021 at 12:00 am
We read with great interest the case report by Pinho et al presenting a successful correction of skeletal open bite by miniscrew-assisted mandibular molar intrusion. (Pinho T, Santos M. Skeletal open bite treated with clear aligners and miniscrews. Am J Orthod Dentofacial Orthop 2021;159:224-33). We appreciated the case report, but we have a concern about possible inferior alveolar nerve (IAN) injury after molar intrusion, considering the molar roots in proximity to the IAN canal.

- Orthodontists’ role in the treatment of dentofacial deformities: Where we are and where we need to beby Jeffrey C. Posnick, Timothy J. Tremont, Leonard B. Kaban on 01/10/2021 at 12:00 am
Humans do not intuitively think in statistical terms and the brain tends to leap from specific information to general conclusions. Once a theory is formulated, we (eg, surgeons, orthodontists, scientists, professors, and students, etc) attempt to align the available evidence with the theory rather than test the hypothesis against existing facts. It is often easier to accept an unproven but perhaps popular or comfortable theory rather than implement change.
