I’ve recently asked J Okeson to mention studies supporting that iatrogenic effects of 24/7 full-coverage splints are caused by muscular adaptation. Here is the list he sent me:
Herring SW, Grimm AF, Grimm BR. Regulation of sarcomere
number in skeletal muscle: a comparison of hypotheses.
Muscle Nerve. 1984;7:161–173.
Williams PE, Goldspink G. Changes in sarcomere length and
physiological properties in immobilized muscle. J Anat.
1978;127(Pt 3):459–468.
Goldspink G. Cellular and molecular aspects of muscle growth,
adaptation and ageing. Gerodontology. 1998;15:35–43.
Hayatsu K, De Deyne PG. Muscle adaptation during distraction
osteogenesis in skeletally immature and mature rabbits.
J Orthop Res. 2001;19:897–905.

C, Meyer DC. Device for lengthening of a musculotendinous
unit by direct continuous traction in the sheep. BMC Vet
Res. 2012;8:50.

M et al. Effects of distraction on muscle length: mechanisms
involved in sarcomerogenesis. Clin Orthop Relat Res. 2002;

Relat Res. 2002;October(403 Suppl):S126–S132.

movement, muscle stiffness, and intramuscular connective
tissue content during surgical limb-lengthening: a study in

ORTHODONTICS THAT WORKS: 2-дневный курс с пошаговым разбором клинических случаев и практикой основных изгибов
When I overcome my moments of weakness, I think that it’s actually great to work in the epicentre of orthodontic quackery. You can help so many victims of splints, articulators, and fancy appliances.
Here is another victim of so-called Brad Pitt’s technique.
Do you know whether they sell extra broad intraoral mirrors together with these extra broad wires?

Happy New Year Everyone! A few minutes ago, I got a notification from the JCO. Our new paper is in print.

Hopefully, we delivered enough nails to the coffin of gnathology. Due to the copyright regulations, I can not share the PDF to a group. But you may contact me directly, and I send a copy to each of you personally.
All in all, subscribe to the JCO.

Analysis and prediction of condylar resorption following orthognathic surgery
Here is an interesting new study on a very important issue. Open access.
“The amount of mandibular advancement was the most important predictor for condylar resorption.”
