Anatomy of the temporomandibular joint appears to have an important role in understanding masticatory system and diseases. Although many articles have reported about the temporomandibular joint anatomy, there is a few reports describing the relations between basic anatomy and clinical condition.
We reviewed current articles about temporomandibular joint anatomy, aimed for clarifying the relations between basic and clinical findings.
Part 1:
We reported about the subject of the condylar osteology, especially, relations between the condylar shape, size and functions: As results, it was appeared that individual functional changing in the masticatory life change the condylar shape and size with demand of function and metabolic changes.

We reviewed current articles about temporomandibular joint anatomy, aimed for clarifying the relations between basic and clinical findings.
Part 2:
We introduced articles about the subject of osteology of the temporal part of the temporomandibular joint, especially, morphology and functions of the eminence and each slopes in the temporal fossa. These articles showed the relation between individual morphological change and the masticatory system, and necessity of establishment of the method for examination where the condylar path through the eminence slope during various mandibular movements.

The preparation of abutment teeth during full mouth reconstruction must be undertaken based on a plan of a series of treatments which leads up to final placement of the prosthesis. This plan begins with the initial prosthetic preparations which include the diagnosis, devising a treatment plan, periodontal and endodontic treatments, oral surgery, and orthodontic treatment. The treatment crowns are then fabricated, the impressions taken, and the proper condylar position, vertical dimension, and occlusal plane, including measurements of mandibular movements, are also determined. The laboratory procedures are then carried out as well as remounting. In addition to preparing the abutment teeth following basic principles, the following points must also be taken into consideration.
1. The shape of the abutment tooth must be simple.
2. The prepared surface of the abutment tooth must be smooth.
3. The orientation of the abutment teeth must be parallel if at all possible.
4. The occlusal surface, vertical dimension, and arch form of the abutment teeth must be in harmony.
5. Auxiliary retentive mechanisms must be included in the abutment teeth.
