Introduction:
This study aimed to introduce a new, less morbid computer-aided design-computer-aided manufacture (CAD-CAM) protocol that limits the excessive anteromedial movement of the mandibular condyle in front of the eminence.
Methods:
Five patients were treated by surgical implantation of bilateral patient-specific polyether-ether ketone (PEEK) onlay eminoplasties; each implant was virtually designed using specific software and milled from medical-grade PEEK blocks. Intraoperatively, each implant was fixed with three mini-screws at the lateral aspect of the zygomatic arch. The follow-up period ranged from six months to two years.
Results:
The mean preoperative maximal incisal mouth opening was (48.8 mm) versus (36.8 mm) for the postoperative measurement, which was statistically significant.
Conclusion:
Patient-specific PEEK eminoplasty is an effective alternative for surgical treatment of chronic recurrent TMJ dislocation.

Ethers from Alcohols: Alcohol Dehydration and Williamson Ether Synthesis
Ethers can be prepared from organic compounds by various methods. Some of them are discussed below,
Preparation of Ethers by Alcohol Dehydration
In this method, in the presence of protic acids, alcohol dehydrates to produce alkenes and ethers under different conditions. For example, in the presence of sulphuric acid, dehydration of ethanol at 413 K yields ethoxyethane, whereas it yields ethene at 443 K.

Structure and Nomenclature of Ethers
Ethers are organic compounds with an ether functional group which is characterized by an oxygen atom connected to two — identical or different — alkyl, aryl, or vinyl groups. The C–O–C linkage in dimethyl ether — the simplest ether — has an approximately tetrahedral bond angle of 110.3 degrees. The oxygen atom is sp3- hybridized, with the C–O distance being about 140 pm.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
